Higher caregiver-adverse childhood experiences (ACEs) have been associated with multiple adverse pediatric outcomes. However, no studies have examined links between caregiver ACEs and infectious outcomes like antibiotic prescriptions or infection-related clinical encounters.

Hepatitis C virus (HCV) testing is recommended for all adults 18 years and older to increase identification of those with infection and facilitate prompt referral for curative antiviral therapy. While critical to promote elimination, this strategy excludes a key demographic group who are clearly at risk of undetected HCV infection and who could benefit from early treatment: adolescents. In this paper, we review the available data on the burden of HCV and the close association with injection drug use, discuss the rationale of universal testing in adolescents and, finally, present data from a quality improvement project implementing HCV testing into routine adolescent health visits.

Hepatitis B virus (HBV) antiviral administration and adherence are essential to reach the World Health Organization's 2030 hepatitis elimination goals. As HBV treatment guidelines are now simplified and expanded, adherence to treatment will be critical, but challenges to adherence are poorly studied. After introducing tenofovir disoproxil fumarate (TDF) monotherapy to expectant mothers with high-risk HBV in Kinshasa, DRC, we conducted semi-structured interviews to understand medication adherence behaviors, to complement pill counts and measurement of TDF metabolite levels. Key facilitators of adherence identified included trust in healthcare workers, a better understanding of HBV, and family support. Identified barriers included fear of stigma and low health literacy. Knowledge about HBV disease remains low, underscoring the importance of ongoing education of clinic staff and patients alike.

There are several antimicrobial options for treating urinary tract infection in children. Although cefdinir is commonly used, better options exist. We developed an intervention bundle to reduce the use of cefdinir in favor of cephalexin. The intervention bundle decreased cefdinir use by 19.1% while use of cephalexin increased by 19.8%.

Respiratory syncytial virus (RSV) poses a global health challenge, particularly among younger children. While the disease burden in Japan has been preliminarily quantified in short-term or inpatient settings, a comprehensive understanding of outpatient settings at a national level is still lacking.

Of 319 children with invasive candidiasis, 67 (21%) transitioned from intravenous to enteral antifungal therapy. Eight (12%) transitioned back to intravenous antifungal therapy, one due to perceived treatment failure defined by clinical progression or worsening. Global treatment response at study completion was success in 66 participants transitioned to enteral therapy.

Eosinophilic meningoencephalitis caused by Angiostrongylus cantonensis has been reported in several southern U.S. states and Hawai'i. We present the first locally acquired human cases of A. cantonensis meningoencephalitis in three children in Florida, occurring between June 2021 and January 2022. Clinicians should be attuned to this possible diagnosis in this region.

A cluster of macrolide-resistant Mycoplasma pneumoniae causing community-acquired pneumonia was observed in children in North Dakota in 2024. Suspicion was raised by non-response to macrolides, with confirmation via a PCR assay. Prompt improvement occurred after initiation of alternative antibiotics.

To determine if healthcare-associated (HA)-RSV is associated with worse outcomes, this multicenter cohort study studied 26 children with HA-RSV and 78 matched non-HA-RSV patients of whom 58% and 55%, respectively, had >2 comorbidities. Overall, 39% of HA-RSV versus 18% of non-HA-RSV patients required respiratory support escalation (aOR 5.1, CI95 1.4,19.1).

Anaerobe-targeted antibiotic (ATA) therapy may adversely impact the developing neonatal microbiome. We describe utilization patterns, potential indications, and related outcomes of ATA therapy in neonatal intensive care units across the US over 13 years. While overall antibiotic use decreased, ATA use was unchanged. Potentially associated indications were inconsistent.

Previous investigations into clinical signs and symptoms associated with influenza types and subtypes have not definitively established differences in the clinical presentation or severity of influenza disease.

Gram-negative bloodstream infections are associated with significant morbidity and mortality in children. Increasing antimicrobial resistance (AMR) is reported globally, yet efforts to track pediatric AMR at a national level over time are lacking.

Rising proportions of antimicrobial resistance (AMR) have been observed in both Staphylococcus aureus and Enterococcus spp. isolates.

Large-scale epidemics in countries with high birth rates can create a concerning scenario where pregnant people are more likely to transmit the virus. Additionally, increased international mobility has made arboviruses a growing problem for travelers. The increased risk of vertical transmission has been related to maternal viremia near delivery. Such transmission leads to severe infection of newborns and may be associated with subsequent neurological impairment including cerebral palsy. This case series provides an overview of clinical and laboratory findings in pregnant individuals with confirmed CHIKV infection as well as the clinical effects on their newborn emphasizing the severity of neonatal chikungunya.

The safety of casirivimab+imdevimab (CAS+IMD) (anti-SARS-CoV-2 monoclonal antibodies [mAbs]) in pediatric outpatients with COVID-19 was evaluated in a randomized, phase 1/2/3 trial. Consistent with adults, CAS+IMD was generally well tolerated with low drug-induced immunogenicity rates. The findings support development of next-generation anti-SARS-CoV-2 mAbs for at-risk pediatric patients.

Primary adjunctive therapy with corticosteroids have been shown to reduce coronary artery abnormalities in high-risk Kawasaki Disease (KD) patients in Japan (RAISE study). We evaluated their effect on outcomes in North American patients with high-risk KD.

While clinical risk factors for RSV bronchiolitis are well established, data on socioeconomic risk factors is lacking. We explored the association of parental education, income, and employment status on an infant's risk of hospitalization for RSV bronchiolitis.
