Diagnosis and Treatment of Iron Deficiency and Iron Deficiency Anemia in Children and Adolescents: Recommendations of the Polish Pediatric Society, the Polish Society of Pediatric Oncology and Hematology, the Polish Society of Neonatology, and the Polish Society of Family Medicine

Background/Objectives. Iron deficiency is one of the most common nutritional deficiencies worldwide and is the leading cause of anemia in the pediatric population (microcytic, hypochromic anemia due to iron deficiency). Moreover, untreated iron deficiency can lead to various systemic consequences and can disrupt the child’s development. Methods/Results. Therefore, a team of experts from the Polish Pediatric Society, the Polish Society of Pediatric Oncology and Hematology, the Polish Neonatology Society, and the Polish Society of Family Medicine, based on a review of the current literature, their own clinical experience, and critical discussion, has developed updated guidelines for the diagnosis, prevention, and treatment of iron deficiency in children from birth to 18 years of age. These recommendations apply to the general population and do not take into account the specifics of individual conditions and diseases.

88 Evaluating the impact of ChatGPT-4 on medical abstracts

Abstract Background Since its launch in November 2022, ChatGPT has received recognition for its use in medical writing. Some even suggested it could write scientific abstracts. However, its real-life effectiveness to help researchers improve conference abstracts remains unexplored. Objectives To evaluate whether ChatGPT 4.0 could improve the quality of abstracts submitted to a medical conference by clinical researchers with various experiences. Design/Methods In October 2023, we conducted an experimental study involving 24 international researchers who provided one “original” abstract intended for submission at the 2024 Pediatric Academic Society (PAS) conference. Our research team created a prompt asking ChatGPT-4 to improve the quality of the abstract while adhering PAS submission guidelines. Researchers received the revised version and were tasked with creating a “final” abstract. The quality of each version (original, ChatGPT and final) was evaluated by the researchers themselves using a numeric scale (0-100). Additionally, three co-investigators assessed abstracts blinded to the version. The primary analysis focused on the mean difference in scores between the final and original abstracts. We also compared scores of the three versions and determined the proportion of researchers reporting ChatGPT's impact on their abstract and its acceptance probability. For an effect size of 0.7, it was estimated that we needed at least 20 pairs of abstracts. Results Abstract quality varied between the three versions with mean scores of 82, 65 and 90 for the original, ChatGPT and final versions, respectively. Overall, the final version displayed significantly improved quality compared to the original (mean difference 8.0 points; 95% CI: 5.6-10.3). Of note, 3 (14%) abstracts remained unchanged between final and original versions. Independent ratings by the co-investigator confirmed statistical improvements (mean difference 0.94 points; 95% CI: 0.44-1.44). Researchers identified minor (n=10) and major (n=3) factual errors in ChatGPT’s abstracts. However, 18 (75%) participants reported that ChatGPT contributed to the enhancement of their final abstract. Ten (42%) participants believed it improved their abstract's chances of acceptance. Eighteen (75%) researchers reported being uncomfortable using ChatGPT version for submission. Conclusion While ChatGPT 4.0 does not produce abstracts of better quality then the one crafted by researchers, it serves as a valuable tool for researchers to enhance the quality of their own abstracts. The utilization of such tools is a potential strategy for researchers seeking to improve their abstracts.

15 Predictive validity of two developmental screening tools at the 18-month visit and neurodevelopmental consultation at an average age of 8 years

Abstract Background The Canadian Paediatric Society (CPS) recommends an enhanced 18-month well-baby visit incorporating a developmental screening tool to stimulate discussion with parents, and notes that a widely used tool is the Nipissing District Developmental Screen (NDDS). For early detection of autism spectrum disorder, the CPS notes that a commonly used screening tool is the Infant Toddler Checklist (ITC). Objectives To examine the predictive validity of the ITC and NDDS at the 18-month visit using later neurodevelopmental consultation as the criterion measure; and examine whether positive developmental screening was associated with health care utilization (HCU). Design/Methods Using a prospective design, parents completed the ITC and the NDDS at the 18-month visit in primary care practices. Seven types of HCU were collected from health administrative databases, via linkage using the child’s health insurance number, including: neurodevelopmental consultation, special paediatric consultation, scheduled primary care visit billings, unscheduled primary care or minor visit billings, other non-primary care visit billings, hospitalizations, and emergency department visits. Covariates included child and family characteristics. We calculated screening test properties (using neurodevelopmental consultation as the criterion) and used multivariable negative binomial regression to estimate rate ratios (RR) for each of the 7 types of HCU. Results For both the ITC (n=1460) and NDDS (n=802) cohorts, mean age at screening was 18 months and mean age at follow up was 8 years. Of the ITC cohort, 11% were screen positive, 2.6% had a neurodevelopmental consultation. A positive ITC had 40% sensitivity (95% CI 24%-57%), 90% specificity (95% CI 88%-91%), 10% false positive rate (95% CI 9%-12%). A positive ITC was associated with 6 of 7 types of HCU, including neurodevelopmental consultation (RR=2.78, 95% CI 1.37-5.67). Of the NDDS cohort, 36% were screen positive, 2.5% had a neurodevelopmental consultation. A positive NDDS had a sensitivity of 50% (95% CI 27%-73%), specificity of 65% (95% CI 61%-68%), false positive rate of 35% (95% CI 31%-40%). A positive NDDS was associated with only 1 of 7 types of HCU: unscheduled primary care or minor visit billings 1.24 (95% CI 1.01, 1.53, p=0.04). Conclusion The predictive validity of the ITC was stronger than the NDDS due to high specificity and low false positive rates. The low sensitivity of the ITC is similar to other screening tools used at 18 months, highlighting the importance of ongoing developmental surveillance. The false positive rate of the NDDS is unacceptably high for a screening tool.

Development and validation of a pediatric internationally agreed ultrasound knee synovitis protocol (PIUS-knee) by the PReS imaging working party

ObjectivesTo identify an optimal pediatric musculoskeletal ultrasound (MSUS) protocol for the detection of knee arthritis in patients with juvenile idiopathic arthritis (JIA) including a comparison with existing protocols. Secondary aims were to correlate MSUS-identified B-Mode (BM) and Power Doppler-Mode (PD) synovitis with clinical findings.MethodsConsecutive JIA patients with confirmed knee arthritis after clinical examination underwent a thorough MSUS study protocol which included views identified and consented by the Pediatric Rheumatology european Society (PReS) Imaging Working Party for the detection of synovitis. In total eight views including measurement of the suprapatellar recess were included. Scoring of synovitis followed the pediatric OMERACT criteria (BM and PD severity grading 0 to 3). Interobserver reliability of BM and PD was tested before study begin. Previously published MSUS protocols for knee synovitis were also identified from the literature and their scan protocols compared to identify differences in sensitivity for synovitis according to the number and specific type of views included. Finally, a clinically applicable MSUS protocol for knee synovitis could be proposed.ResultsIn 114 patients with clinically active knee inflammation, BM positivity (grading ≥ 1) was most frequently detected in the suprapatellar longitudinal and transverse scans performed in any positioning (frequency 97–99% in suprapatellar longitudinal in 30° or neutral respectively). PD positivity was however higher in these views performed in 30° flexion compared to neutral. Intrasynovial PD positivity (grading ≥ 1) was most frequently detected in the lateral parapatellar (69%, sensitivity 0.68, specificity 0.98), medial parapatellar (frequency 67%, sensitivity 0.67, specificity 1.0), the longitudinal lateral (68%, sensitivity 0.67, specificity 0.98) and suprapatellar transverse in 30° (frequency 64%, sensitivity 0.64, specificity 1.0). A combination of five views was the most sensitive for BM and PD synovitis. The suprapatellar recess size was analyzed by age and gender. For each group, the recess was wider in knees with arthritis than without (p < 0.001). Interobserver reliability of BM and PD positivity showed 85% agreement, with kappa 0.74 (very good). Three published studies with knee synovitis MSUS protocols were identified, which included a range of 1–3 views. Evaluation of the sensitivity of positive PD findings of each of these protocols reached a range of 53–83%; the highest sensitivity (91%) was achieved with the 5 views as identified by this study. These five views were therefore combined to form the Pediatric Internationally agreed Ultrasound (PIUS) knee protocol.ConclusionBM and PD positivity reliably correlated with the identification of pathological findings in knees of patients with JIA. From an internationally agreed protocol of eight images, a combination of five showed the greatest sensitivity for synovitis. This protocol, termed ‘PIUS-Knee’ performed well when compared to existing protocols.

Arsenic in Rice: A Call to Change Feeding Substitution Practices for Pediatric Otolaryngology Patients.

Rice products are ubiquitous in the diets of American children and are often utilized to thicken feeds as part of treatments for gastroesophageal reflux disease in infants. However, a 2015 Food and Drug Administration investigation demonstrated that they contain unsafe levels of inorganic arsenic. Inorganic arsenic exposure has been linked to serious health issues including skin, lung, and bladder cancer. Smaller children are put at higher risk due to the increased arsenic-to-weight ratio compared to adults, threatening their development in multiple ways. Other thickeners offer cost-effective, safer alternatives. With this communication, we aim to raise awareness of this issue within the otolaryngology practice thereby bringing us abreast of the best practices of the pediatric and gastrointestinal medical societies who have recommended against the use of rice for thickening feeds, instead advocating for alternate natural thickening agents like wheat or oatmeal.

Current state of quality improvement research across cardiac ICUs: a Pediatric Cardiac Intensive Care Society (PCICS) survey.

Outcomes for children with heart disease improved over the past decades. Quality improvement (QI) research in paediatric cardiac critical care is a key driver of improvement. The availability and variability of QI research across the field is unknown. This project represents a step in understanding the role. The Pediatric Cardiac Intensive Care Society (PCICS) can serve to support institutions' needs, drive collaborations, and utilise available infrastructure at member institutions for improvement work. The PCICS Quality Improvement and Safety Committee developed a survey to assess the state of QI research. The survey was disseminated over several months and available via QR code at the World Congress of Pediatric Cardiology and Cardiac Surgery in 2023. Fifty-eight respondents completed the survey representing at least 38 unique institutions. Most respondents participated in QI research (52/58, 90%). Most QI projects were single centre (41% of respondents), and of those, the majority were from a minority of institutions (13 institutions [34% of total institutions]). QI support is available at slightly more than half of units, and 55% (32/58) have access to a QI specialist. QI support and rate of publications is significantly lower for small/medium units as compared to large units. Respondents suggested most interest from PCICS in networking with other members with similar project ideas (50/58, 86%). PCICS member institutions are committed to QI research, with limitations in support, local specialists, and networking. Increasing connectivity and accessibility to QI resources may reduce burden to individual members and institutions to achieve QI research.

Validation of the Diabetomics CovAB SARS-CoV-2 antibody test in children: comparison with serology.

Recently a study determining the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in unvaccinated children in NJ (Katic et al. 2023. Pediatric Academic Societies Meeting; Washington, D.C. https://2023.pas-meeting.org/searchbyposterbucket.asp?bm=Public+Health+%26+Prevention&t=Public+Health+%26+Prevention&pfp=Track) was conducted using a gum swab method for antibody detection. The Diabetomics CovAB test, which qualitatively identifies antibodies to SARS-CoV-2 spike protein, is a point-of-care, low-cost test, that is easy to administer in children. While this test provides sensitive and specific results in adults [US Food and Drug Administration (FDA). 2022. Center for devices and radiological health. EUA authorized serology test performance. Available from: https://www.fda.gov/medical-devices/covid-19-emergency-use-authorizations-medical-devices/eua-authorized-serology-test-performance], data on its accuracy in children is lacking. As a follow-up to the above-mentioned study, we compared the results of the gum swab test to a serologic antibody test. We found that the gum swab test was inferior to serology but was fairly sensitive and specific with a high positive predictive value. While the test is not ideal for diagnostic purposes in children it can be a valuable tool for public health officials and pediatricians to understand the extent of past health interventions.

New US DHHS Guidelines for Feeding of HIV Exposed Infants: Uptake, Practice Variability and Concerns

Abstract Background Approximately 5000 infants are born to mothers living with HIV annually in the US. In the past, the Center for Disease Control (CDC), American Academy of Pediatrics (AAP), and US Department of Health and Human Services (DHHS) have recommended that people living with HIV (PWH) not breast/chest feed their infants. Recent changes published in January 2023 in the “Section on Infant Feeding for Individuals Living with HIV” in the US DHHS HIV Guidelines, now include that individuals with HIV who are on antiretroviral therapy (ART) with a sustained undetectable viral load (VL) and who choose to breastfeed should be supported in this decision. We evaluated the uptake of these guidelines, and practice variability across providers who care for such mothers and infants. Methods We surveyed Pediatric Infectious Diseases Society members who practice clinically in the US, via an internal email list serve. The ten-question survey assessed uptake of the updated DHHS guidelines and respondents’ clinical practice in three key areas that are subject to interpretation in the guidelines: VL control, mixed feeding, and ART prophylaxis. We used descriptive statistics to examine guideline uptake and variability in practice. We used inductive qualitative thematic analysis to identify themes in open-ended survey responses. Results Of 915 individuals who opened the survey, 165 responded and 129 were included in the final analysis. Respondents represented 86 US clinical centers. Uptake varied: 14 respondents (10.8%) were unaware of the new guidelines, 103 (79.8%) had implemented or were planning to implement the new guidelines, and 12 (9.3%) were not planning to implement the guidelines. The table summarizes variability in pre-delivery VL suppression and mixed feeding criteria used by 117 respondents who are either planning/already implementing guidelines or who are unaware of guidelines. Areas of concern revealed by thematic analysis included insufficient data to support guidelines and lack of specific criteria for implementation. Conclusion We identified substantial heterogeneity in provider uptake and comfort with new breastfeeding guidelines among US pediatric infectious diseases practitioners, and variability in assessment of safety to breastfeed. Further research is essential to explore patient preferences, define necessary follow-up, and address provider concerns regarding insufficient data to support guidelines and lack of specific criteria for implementation.

National Institutes of Health COVID-19 Treatment Guidelines Panel: Perspectives and Lessons Learned.

In March 2020, the White House Coronavirus Task Force determined that clinicians in the United States needed expert treatment guidelines to optimally manage patients with COVID-19, a potentially life-threatening disease caused by a new pathogen for which no specific treatments were known to be effective. The U.S. Department of Health and Human Services requested that the National Institutes of Health (NIH) take the lead in expeditiously convening a panel of experts to create "living" guidelines that would be widely accessible and capable of frequent updating as important new information became available. The purpose of this article is to expand on the experiences of the NIH COVID-19 Treatment Guidelines Panel (the Panel) over the past 4 years, summarize the Panel's final recommendations for COVID-19, highlight some challenges and unanswered questions about COVID-19 management, and inform future responses to public health emergencies. The Panel was formed in March 2020, and the first iteration of the guidelines was released in April 2020. Now that the public health emergency has ended, the NIH COVID-19 Treatment Guidelines have sunsetted. This role will now fall to professional societies and organizations, such as the American College of Physicians, the Infectious Diseases Society of America, the Pediatric Infectious Diseases Society, and the World Health Organization, all of which have been active in this area.

Prevalence and Impact of Recurrent Rejection on Pediatric Heart TransplantRecipients: APHTS Multi-Institutional Analysis.

Studies evaluating the prevalence and impact of recurrent rejection (RR) in pediatric heart transplant (HT) are sparse. The purpose of this study was to describe prevalence and impact of RR on cardiac allograft vasculopathy (CAV) and graft loss after pediatric HT. Data on HT from January 1, 2000, to June 30, 2020, in the Pediatric Heart Transplant Society database were included. Freedom from RR (≥2 rejection episodes) was compared by era (early: 2000-2009; current: 2010-2020). Outcomes for children experiencing RR were compared with those experiencing 0 or 1 rejection episodes and by type of RR (antibody-mediated rejection [AMR], acute cellular rejection [ACR], mixed [ACR/AMR]). Of 6,342 HT recipients, 1,035 (17%) experienced RR. In the current era, pediatric HT recipients were less likely to experience RR (P< 0.001). Freedom from CAV was similar for those experiencing RR to those experiencing 0 or 1 episode (96.6% vs 95.3% vs 96.6%); and similar regardless of the type of RR (AMR, ACR, or mixed) (65.5% vs 82.9% vs 100%) (P > 0.05). Freedom from graft loss was significantly lower for those experiencing RR to those experiencing 0 or 1 episode (56.3% vs 72.3% vs 82.3%) and lower for those experiencing recurrent mixed rejection or recurrent AMR compared with those experiencing recurrent ACR (65.3% vs 50% vs 81.8%). Black children experiencing RR subsequently had lower freedom from CAV and graft loss than White children (P< 0.05 for all). Although prevalence of RR has decreased, children experiencing RR are at greatly increased risk for losing their graft, particularly those who have recurrent mixed or antibody-mediated rejection.

Heart transplantation for pediatric patients with malignant arrhythmias: Indications and Outcomes

BackgroundArrhythmias can lead to cardiac arrest (CA) and heart failure. When intractable, heart transplant (HTX) can become the only viable treatment. This rare, high-risk cohort has not been reported as a distinct group. ObjectiveCharacterize the outcomes of pediatric patients listed for HTX with the primary indication being malignant arrhythmia (MA). MethodsUsing the Pediatric Heart Transplant Society prospective registry, we identified all patients <18 years-old listed between 2014-2022. MA as the listing indication was categorized into primary tachy-arrhythmia (PT), inherited arrhythmia (IA), congenital heart disease (CHD) and cardiomyopathy (CM) with secondary arrhythmia. Demographic, listing and transplant data were analyzed. ResultsAmong 4630 patients listed and 3317 transplanted, MA was the indication in 63 (1.4%) and 49 (1.5%), respectively. MA patients were categorized as PT in 11, IA in 4, CHD in 6 and CM in 42. When compared to the non-MA cohort, patients listed for MA were older (mean (SD) age 10.6 (6.2) vs. 6.1 (6.2) years, p<0.01), more likely to present with a CA (43% vs. 11%, p<0.01), and less likely to be in the intensive care unit (40% vs. 58%, p<0.01) or on inotropes (30% vs. 60%, p<0.01) at listing. Outcomes including waitlist mortality, transplantation, post-transplant survival and freedom from rejection were comparable to the non-MA cohort. ConclusionPatients with MA constitute a small proportion of those listed for HTX in childhood. CM was the most common category, while IA and PT were rare. Their waitlist mortality and post-transplant outcomes were comparable to the non-MA cohort.

Assessing vaccine hesitancy among healthcare providers in Brazil: the influence of vaccine status and professional experience

ObjectiveAssess the occurrence of vaccine hesitancy among pediatricians and their patients and identify potential predictors to mitigate hesitancy among them. MethodsThe study is a cross-sectional survey using an online questionnaire sent to pediatricians affiliated with the Brazilian Society of Pediatrics. The data was analyzed using statistical methods such as exploratory factor analysis, principal component analysis, correspondence analysis, and generalized linear mixed models. ResultsA total of 982 respondents, with a majority being females (77.4%), participated in the research. Among them, the proportion of pediatricians with complete vaccine status was 41.14%, while 90.6% had undergone medical residency. Furthermore, 9.3% worked in public healthcare settings, 30.4% in private settings, and 60.3% in mixed healthcare settings. The analysis revealed a significant association between vaccine status and pediatricians’ misconceptions about COVID-19 vaccines, with those having complete vaccine status showing lower misconceptions (mean difference of -0.15, p = 0.010). Moreover, pediatricians with medical residency experience exhibited fewer misconceptions about COVID-19 vaccines (mean difference of -0.33, p = 0.002). Additionally, correspondence analysis unveiled the presence of two distinct profiles among pediatricians, showcasing variations in vaccine education, professional experience, and vaccine confidence perceptions. ConclusionThe study highlights the influence of vaccine status and medical residency experience on pediatricians’ attitudes and misconceptions about vaccines, emphasizing the need for targeted educational interventions to promote vaccine confidence and combat hesitancy within the healthcare provider community.

Neonatal hypoglycemia: a review of the current diagnostic and management guidelines

Neonatal hypoglycemia is the most common metabolic disorder during the neonatal period. Despite its frequency of occurrence, there is no specific glucose concentration that defines it. Various symptoms and clinical manifestations characterize it, and its complications are related to its severity and duration. This review aims at comparing the recommendations of the American Academy of Pediatrics, the Pediatric Endocrine Society, and the Academy of Breastfeeding Medicine regarding the risk factors, the diagnosis, and the management of hypoglycemia. The complexity of hypoglycemia management and the research questions that need to be answered are highlighted by comparing the three guidelines. Preventing neonatal hypoglycemia by monitoring the maternal glucose concentrations, exploring and defining the optimal glycemic targets, investigating the long-term benefits after following these guidelines, and searching for less invasive diagnostic and therapeutic tools may help healthcare professionals make informed decisions to achieve better outcomes for these neonates.

The Clinical Lens: It is time to start using the right test for febrile young infants

Abstract Fever among infants in the first months of life is a common clinical conundrum facing all clinicians who treat children. Most well-appearing febrile young infants have viral illnesses. However, it is critical to identify those at risk of invasive bacterial infections, specifically bacteremia and bacterial meningitis. Clinicians must balance the risks of missing these infections against the harms of over-investigation. Procalcitonin testing is currently the best diagnostic test available to help guide management, and the Canadian Paediatric Society Position Statement on the management of febrile young infants recommends procalcitonin-based risk stratification. However, in many clinical settings, procalcitonin is either unavailable or has a turnaround time that is too long to aid decision-making. Clinicians who care for febrile young infants must have rapid access to procalcitonin results to provide best-evidence, guideline-adherent care. The wider availability of this test is essential to reduce unnecessary invasive testing, hospitalizations, and antibiotic exposure and could reduce system-wide resource utilization.

An Evidence-Based Measure to Assess Self-Efficacy Among Adolescents With Type 1 Diabetes Mellitus in Jordan.

The purpose of the study was to assess self-efficacy among adolescents with type 1 diabetes mellitus and to identify its contributing factors using a new measure based on the International Society for Pediatric and Adolescent Diabetes Guidelines: the Type 1 Diabetes Mellitus Self-Efficacy Scale (T1DM-SES). A descriptive, cross-sectional design was used to collect data from 161 adolescents ages between 12 and 18 via an online questionnaire survey, including demographic and management-related variables and the 21 items of T1DM-SES. Results demonstrated that adolescents had high self-efficacy levels regarding the basic needs to manage their diabetes and relatively moderate and low levels regarding more sophisticated needs, such as adjusting insulin dose to correct fluctuated glucose levels, covering carbohydrates, and managing ketoacidosis at home. Adolescent females and adolescents who have working mothers or caregivers demonstrated higher levels of self-efficacy, whereas adolescents who have another family member with T1DM reported lower levels. Assessing adolescents' self-efficacy using evidence-based measures is crucial for informing health education plans. There should be a greater focus on acquiring the advanced knowledge and skills necessary for adolescents to manage the constantly evolving challenges of diabetes management. Access to health care and sufficient health insurance coverage that encompasses modern technology are fundamental for the effective management of T1DM.

T cell responses and clinical symptoms among infants with congenital cytomegalovirus infection.

BACKGROUNDCongenital cytomegalovirus (cCMV) infection can cause developmental impairment and sensorineural hearing loss (SNHL). To determine the relationship between immune responses to cCMV infection and neurologic sequelae, T cell responses were compared for their connection to clinical symptoms at birth and neurodevelopmental outcomes.METHODSThirty cCMV-infected and 15 uninfected infants were enrolled in a single-center prospective observational case-control study. T cell pp65-specific cytokine responses; CD57, CD28, and PD-1 expression; and memory subsets were compared.RESULTSInfected neonates (73% symptomatic at birth) lacked pp65-specific cytokine-secreting T cells, with elevated frequencies of CD57+, CD28-, and PD-1+CD8+ T cells and effector memory subsets. Though frequencies overlapped between cCMV symptom groups, asymptomatic infants had higher frequencies of CD57+PD-1+CD8+ T cells. Neonates with subsequent developmental delay lacked detectable CMV-specific T cell responses, with patterns resembling those of uninfected infants. Two children with progressive SNHL had high frequencies of PD-1+CD8+ T cells over the first year compared with children without progressive SNHL.CONCLUSIONSimilar to published reports, neonatal viral antigen-specific cytokine-secreting T cell responses were not detected, but overall patterns indicate that globally differentiated memory CD8+ T cell populations were induced by cCMV infection, with higher frequencies of terminally differentiated PD-1+CD8+ T cells potentially associated with asymptomatic infection. In this cohort, a lack of in utero T cell differentiation was associated with developmental delay, and high frequencies of PD-1+CD8+ T cells persisted only in children with progressive SNHL. Further work is needed to define the specificity of these T cells and their mechanistic connection to these outcomes.FUNDINGThis study was funded through an intramural research award at Nationwide Children's Hospital, the Pediatric Infectious Disease Society Fellowship Award funded by Stanley and Susan Plotkin and Sanofi Pasteur, the Abigail Wexner Research Institute at Nationwide Children's Hospital, and the Pichichero Family Foundation Vaccines for Children Initiative Research Award from the Pediatric Infectious Diseases Society Foundation.

Deciphering the role of lactate as aprognostic indicator in pediatric diabetic ketoacidosis.

Serum lactate levels have been recognized as arobust marker for predicting disease severity and survival in many critically ill children but consensus is lacking regarding its utility in diabetic ketoacidosis. This study aimed to investigate the relationship between initial lactate levels and disease severity in pediatric patients presenting with diabetic ketoacidosis. This single-center retrospective descriptive study involved pediatric patients with diabetic ketoacidosis in the pediatric emergency department between January 2022 and April 2023. Patients were diagnosed using the International Society for Pediatric and Adolescent Diabetes 2022 guidelines. Among the 112 patients included in the study, 41 (36.6%) were classified as mild, 42 (34.8%) as moderate and 32 (28.6%) as severe acidosis. Astatistically significant difference was observed between the time to resolution and clinical severity of diabetic ketoacidosis (p < 0.001). Elevated lactate levels of 2.5 mmol/L or above were detected in 37.5% (42/112) of our patients and asignificant increase in clinical severity was observed as lactate levels increased (p < 0.001). Correlation analysis revealed no significant relationship between lactate levels and time to resolution of diabetic ketoacidosis or length of intensive care unit stay. Multivariate analysis demonstrated asignificant association between lactate levels and severity of acidosis (p: 0.046). Although there is an association between the severity of acidosis and lactate levels in diabetic ketoacidosis, contrary to expectations, this relationship was not found to be associated with adverse outcomes. An important point not to be overlooked by pediatricians is that elevated lactate levels in diabetic ketoacidosis may not always herald poor outcomes.

Risk perceptions of Italian paediatricians for the impact of climate change on children’s health

BackgroundsThis study delves into the risk perceptions of Italian pediatricians concerning climate change's impact on children's health. Given children's heightened vulnerability to climate-related health risks, comprehending these perceptions is crucial. A review of pertinent literature establishes the framework, emphasizing six key factors influencing children's susceptibility to climate-related health hazards.MethodsMethodologically, the study utilized a survey tool developed collaboratively with the Italian Society of Pediatrics (SIP), garnering responses from a representative sample of Italian pediatricians.ResultsFindings indicate a high level of awareness among respondents regarding climate change and its health implications, with a majority attributing it primarily to human activity. Pediatricians recognize various current and anticipated health impacts of climate change, notably concerning illnesses linked to outdoor air quality. Despite acknowledging their role in addressing climate-related health concerns, respondents also cite barriers to engagement, including time constraints and knowledge gaps. However, they express interest in resources like professional training and policy statements to bolster their capacity for effective communication and advocacy.ConclusionsComparisons with prior studies highlight the consistency of findings across diverse contexts and underscore the significance of integrating climate and environmental health education into medical training. Overall, this study sheds light on pediatricians' perspectives in tackling the convergence of climate change and children's health, pinpointing avenues for enhancing their involvement in climate advocacy and mitigation efforts.

Recommendations for Reducing the Environmental Impact of Inhalers in Portugal: Consensus Document

This consensus document addresses the reduction of the environmental impact of inhalers in Portugal. It was prepared by the Portuguese Council for Health and the Environment and the societies representing the specialties that account for these drugs' largest volume of prescriptions, namely the Portuguese Society of Pulmonology, the Portuguese Society of Allergology and Clinical Immunology, the Portuguese Society of Pediatrics, the Portuguese Society of Internal Medicine, the Portuguese Association of General and Family Medicine and also a patient association, the Respira Association. The document acknowledges the significant impact of pressurized metered-dose inhalers on greenhouse gas emissions and highlights the need to transition to more sustainable alternatives. The carbon footprint of pressurized metered-dose inhalers and dry powder inhalers in Portugal was calculated, and the level of awareness among prescribing physicians on this topic was also estimated. Finally, recommendations were developed to accelerate the reduction of the ecological footprint of inhalers.
