When Probiotics Guidelines Differ: A Practical Guide For Clinicians And Researchers, Geoffrey A Preidis, Hania Szajewska, Marla Cunningham, Howard Bauchner, Daniel J Merenstein

Faculty, Staff and Students Publications

Many professional organizations publish clinical practice guidelines for the use of probiotics in gastrointestinal disorders. Generally, no two guidelines align perfectly, and some differ markedly. These discrepancies occur because clinical practice guidelines are not purely mechanical outputs of data synthesis. They are shaped by structured interpretation, value judgments, and predefined thresholds for uncertainty. These elements become particularly visible when effect sizes are small, heterogeneity is high, and outcomes vary in clinical relevance-as is the case with probiotic research. This article examines why discordance among probiotic guidelines is predictable and provides practical guidance for clinicians who must decide among conflicting recommendations …

BACKGROUND: There are few prospective studies of mycophenolate mofetil (MMF) versus cyclophosphamide (CYC) for pediatric lupus nephritis (pLN) and none evaluating rituximab (RTX).

METHODS: The Prospective Pediatric Lupus Nephritis Registry (ProPeL-R) enrolled patients <  21 years within 4 weeks of an initial kidney biopsy diagnostic of pLN. Demographic, clinical, and laboratory data were collected prospectively at enrollment, 3 months, 6 months, and then every 6 months thereafter for up to 5 years of follow-up. For this study, we compared patients receiving initial therapy with corticosteroids (CS) and either MMF (n = 33) vs. CYC (n = 18), and those treated with CS, either MMF or CYC, with RTX (n = 20) vs. without RTX (n = 51).

RESULTS: Histology consisted of 18% class III; 35% class IV; 25% mixed class; and 22% pure class V. Eighty-two percent were female. No significant differences in response or infection rates were identified between those receiving MMF or CYC. There was a significant increase in combined complete (CR) and partial response (PR) at 24 months with RTX use. Overall CR rates at 6 and 24 months were 35% …

Kawasaki disease (KD) and Multisystem Inflammatory Syndrome in Children (MIS-C) are systemic inflammatory diseases sharing clinical and laboratory features. Gastrointestinal (GI) symptoms are common presenting features of both conditions. We aimed to determine the association of GI symptoms and clinical features and outcomes for KD and MIS-C. The International Kawasaki Disease Registry enrolled contemporaneous KD and MIS-C patients <  18 years of age from 42 sites from January 1, 2020, through October 31, 2023. The association of GI symptoms (abdominal pain, vomiting and diarrhea), demographics, clinical and laboratory features, and cardiac involvement were determined using ordinal logistic regression incorporating interaction terms with diagnosis. We included 883 KD and 1827 MIS-C patients with confirmed diagnostic criteria. The presence of at least one GI symptom (vomiting, abdominal pain, diarrhea) was more prevalent for MIS-C patients (88% versus 57%; p <  0.001). A greater number of GI symptoms was significantly associated with older age and higher adiposity, presentation with shock, intensive care unit admission, inotropic support, and greater immunomodulatory therapy. Greater number of GI symptoms was significantly associated with higher peak markers of inflammation and organ dysfunction, and higher peak NT-proBNP and lower left ventricular ejection fraction, but not with coronary artery involvement. There were few differences related to diagnosis group. A greater number of presenting GI features is associated with features that may indicate a more severe form of KD and MIS-C, including cardiac involvement, and may merit increased attention.

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Urinary tract and kidney infections are potential complications in pediatric chronic kidney disease (CKD), especially among patients with congenital anomalies of the kidney and urinary tract (CAKUT). We characterized the prevalence of self-reported infections from childhood through young adulthood; evaluated risk factors; and quantified the association with CKD progression.

METHODS: Infections in the past year were self-reported at annual Chronic Kidney Disease in Children (CKiD) study visits. Age-specific infection prevalences were stratified by sex and CKD diagnoses (glomerular, non-glomerular non-CAKUT, CAKUT low-risk for infections, and three CAKUT high-risk categories: reflux nephropathy, obstructive uropathy, and other high-risk). Repeated measures logistic …

Ceftaroline Pharmacokinetics On Ecmo, A Pediatric Case Report., Kathryn Pavia, Ashton Bellamy, Alaina Burns, Allison Scott, Ethan A. Poweleit

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: In-vitro studies suggest that patients on extracorporeal membrane oxygenation (ECMO) may struggle to achieve therapeutic ceftaroline exposure to treat infections due to antibiotic sequestration within the ECMO oxygenator; however, there are no published data regarding ceftaroline concentrations from patients supported by ECMO.

PATIENT PRESENTATION: Here we present an analysis of ceftaroline pharmacokinetics in a 5-y-old patient supported on ECMO due to influenza-associated necrotizing pneumonia.

RESULTS: A total of nine concentrations were analyzed, including three concentrations prior to cannulation and six on ECMO. ECMO cannulation was associated with a relatively small change in the volume of distribution (0.17 L/kg to …

Multivariable logistic regression models, adjusted for age, sex, and body mass index z-score, …

Peritoneal Dialysis Catheter Complications In Neonates With Kidney Failure., Shannon Reinert, Maanasa Yarlagadda, Alexander Bondoc, Donna Claes, Stefanie Riddle, Meredith P. Schuh

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Neonates with kidney failure require placement of a peritoneal dialysis catheter (PD-C) shortly after birth. PD-C malfunction and peritonitis, both common in this population, are associated with PD failure. The aim of this study was to describe our center's PD-C-related practices and outcomes in neonates with kidney failure.

METHODS: We performed a retrospective chart review of neonates who required kidney replacement therapy (KRT) within the first 30 days of life from 01/2018-12/2023. We evaluated for PD-C duration, PD-C replacement or revision, and peritonitis.

RESULTS: Twenty-four neonates had PD-C placed for chronic dialysis at a median of 9.7 days and …

An Evaluation Of Southern Nevada’S Pediatric Care Ecosystem, David Damore, Tina Quigley, Nick Fiore

Policy Briefs and Reports

In 2024, The Lincy Institute and the Nevada Health and Bioscience Corporation released a report prepared by the consulting firm Tripp Umbach detailing the case for a stand-alone children’s hospital in Southern Nevada. Shortly thereafter, Intermountain Health announced it would build Nevada’s first such facility in Las Vegas, expected to open in 2030. To complement the hospital’s development, The Lincy Institute undertook an independent evaluation of the regional pediatric care landscape. The analysis draws on secondary data and discussions with advocates, health system administrators, practitioners, and providers. The report examines:

• Fiscal, resource, and workforce challenges underlying Nevada’s poor population-level pediatric …

Strengthening Health System-Community Partnerships To Address Pediatric Social Needs: A Qualitative Study, Joy Friedman, Melissa A. Alderfer, Kelsey Higgins, Aaron Carpenter, Jennifer Sciolla, Sarah E. Wawrzynski

Department of Pediatrics Faculty Papers

IntroductionStructural and social conditions influence pediatric health outcomes. Successful implementation of social needs screening and referral programs depends on community-based organizations (CBOs) to provide resources that address health-related social needs (HRSN). We explored current practices and perspectives of health care workers and CBO representatives on improving health system-CBO partnerships.MethodsParticipants were purposively recruited from a variety of health care settings involved in HRSN screening and CBOs delivering resources in the community. Participants completed semi-structured interviews. Qualitative thematic analysis was used to summarize data.ResultsTen key informants participated (six health care workers and four CBO representatives). Four themes were identified: 1) mismatches in …

Black race and Hispanic ethnicity are associated with higher mortality in severe combined immunodeficiency (SCID) following hematopoietic cell transplantation (HCT), though mechanisms remain unclear. We evaluated 796 children with SCID who received nonsibling HCT between 1982 and 2020 using data from the Primary Immune Deficiency Treatment Consortium. Overall survival for Black (aHR 2.47, 95%CI 1.64, 3.71) and Asian/Pacific Islander patients (aHR 1.82, 95%CI 1.00, 3.30) was significantly lower compared with non-Hispanic White patients, while Hispanic patients had lower event-free survival (aHR 1.83, 95%CI 1.27, 2.63) compared with non-Hispanic White patients. Even after adjusting for age and infection, Black patients with …

Posaconazole Target Attainment In Critically Ill Children: A 15-Year Single-Center Retrospective Analysis., Kathryn Pavia, Addison M. Pritchett Ms, Jennifer Goldman

Manuscripts, Articles, Book Chapters and Other Papers

Posaconazole is a triazole antifungal agent used for prophylaxis and treatment of invasive fungal diseases. Posaconazole has high inter-individual variability in dose-exposure relationship and benefits from therapeutic drug monitoring (TDM). Adult studies report particularly high rates of subtherapeutic exposure among intensive care unit (ICU) patients related to changes in physiology during critical illness. The rates of subtherapeutic posaconazole exposure among critically ill children in ICU's are unknown. This single-center retrospective analysis at a large freestanding children's hospital used TDM results from 2010 to 2025 obtained while patients were undergoing care in a pediatric ICU. Therapeutic targets were ≥ 1.0 mg/L …

BACKGROUND: Slower chronic kidney disease (CKD) progression allows more time for transplant preparation. Whether differences in CKD progression by race/ethnicity associate with preemptive or living donor transplantation in youth has not been well studied.

METHODS: We examined the association between time spent with low eGFR (between 10-30 mL/min/1.73 m²) and odds of preemptive or living donor transplantation among youth with CKD. eGFR was estimated using the bedside Schwartz (if < 18 years) and CKD-EPI 2021 equations (if ≥ 18 years) and the CKiD U25 equation in sensitivity analysis. Time spent with low eGFR was compared by race/ethnicity.

RESULTS: Among 333 youth with CKD (median age 11 years [IQR 7,14]), median time spent with low eGFR was 28.8 months. 77% were preemptively waitlisted, and 45% received preemptive …

Patient-Specific Computational Fluid Dynamics Modeling Of Airway Collapse In Infants With Robin Sequence., Gautam Jalori, Michael Barbour, Michael Bindschadler, Kelly Evans, John P. Dahl, Alberto Aliseda

Manuscripts, Articles, Book Chapters and Other Papers

Robin Sequence (RS) is a congenital condition in which patients experience dynamic, periodic obstruction or collapse of the upper airway due to an underdeveloped jaw and a posteriorly displaced tongue. Current clinical techniques for evaluating airway obstruction do not provide quantifiable data and fail to account for the dynamic nature of obstruction or collapse. There is no standardized criterion to characterize obstruction or collapse severity. This study presents the first method that extracts airway motion from 4-dimensional computed tomography and performs a patient-specific, moving-mesh computational fluid dynamics (CFD) analysis of RS patients with complete airway collapse or obstruction. To quantify …

Using Early And Periodic Screening, Diagnostic, And Treatment (Epsdt) To Improve Access To Obesity Pharmacotherapy: A Practical Guide For Clinicians Caring For Youth With Obesity Across United States Medicaid Programs:, Jaime M. Moore, Valerie M. O'Hara, Cassie Totman, Brooke Sweeney, Sarah Hampl, Alaina P. Vidmar

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Coverage of obesity pharmacotherapy for youth varies substantially across state Medicaid programs. This variability limits access to evidence-based treatment for pediatric obesity. The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit is a federally mandated Medicaid provision requiring coverage of medically necessary services for individuals under age 21, even when such services are not included in standard state Medicaid benefits. Despite its broad scope, EPSDT remains underutilized due to limited awareness and operational complexity.

METHODS: We developed a clinician-facing, practice-oriented framework to operationalize EPSDT for pediatric obesity treatment. This approach integrates (1) review of federal EPSDT policy and …

Vomica And Respiratory Distress: A Complicated Lung Hydatid Cyst In A Child., Riccardo Guanà, Antonella Peduto, Maria Grazia Sacco Casamassima, Marco Denina, Marco Petraz, Cristina Giuliano, Giuseppe Farruggio, Lucia Gerbaudo, Fabrizio Gennari

Manuscripts, Articles, Book Chapters and Other Papers

Hydatid cyst, caused by Echinococcus infection, is the most common parasitic lung infection in children. Giant cysts are generally the result of a late diagnosis and are associated with a high risk of spontaneous rupture and life-threatening complications, including anaphylactic shock. We present the complex management of a large, complicated hydatid cyst of the lung in an 11-year-old boy in a nonendemic area. This case highlighted the specific work-up and surgical treatment of lung cysts as well as the differential diagnosis to consider when treating pulmonary masses or pneumonia.
