Neonatology (Perinatology)
Oral administration of bone marrow-derived mesenchymal stem cells attenuates intestinal injury in necrotizing enterocolitis   (3,154 times)
Yeong Seok Lee, Yong Hoon Jun, Juyoung Lee
Clin Exp Pediatr. 2024;67(3):152-160.   Published online February 19, 2024
Question: What is the optimal dose of bone marrow-derived mesenchymal stem cells (BM-MSCs) for treating necrotizing enterocolitis (NEC), and is orally administered BM-MSC effective?
Findings: High (1×106 cells) or multiple BM-MSC doses showed similar effects as low (1×105 cells) doses of intraperitoneally administered BM-MSCs. Furthermore, orally administered BM-MSCs were as effective as intraperitoneally administered BM-MSCs.
Meaning: Orally administered low-dose BM-MSCs are a potential treatment for NEC.
Neurology

Raffaele Falsaperla, Silvia Marino, Carla Moscheo, Lucia Giovanna Tardino, Simona Domenica Marino, Concetta Sciuto, Piero Pavone, Giovanna Vitaliti, Federica Sullo, Martino Ruggieri
Clin Exp Pediatr. 2023;66(8):350-356.   Published online June 14, 2023
Question: What are the current palliative care protocols, palliative course, and implementable palliative care programs for hospitalized pediatric patients with neurological diseases in Italy?
Finding: We studied 34 newborns with nervous system diseases, all of whom had a poor prognosis.
Meaning: Despite current legislation in Italy, no palliative care network has been implemented. Given the vast number of patients with neurological conditions, standardized palliative care guidelines and protocols are required.

Maryam Barzin, Shirin Yaghoobpoor, Maryam Mahdavi, Behnaz Abiri, Majid Valizadeh, Fereidoun Azizi, Pooneh Dehghan, Farhad Hosseinpanah
Clin Exp Pediatr. 2024;67(12):694-703.   Published online September 12, 2024
Question: What is the prevalence of HTN among adolescents enrolled in the TLGS according to 3 different accepted definitions (4th report, ESH, and AAP-CPG). Also, what is the ability of each of these definitions in predicting early adulthood CIMT, as a surrogate for cardiovascular disease events?
Finding: The highest and lowest prevalence of stage 1 HTN was observed with the AAP-CPG (17.7%) and ESH (8.8%), respectively. Similarly, the highest and lowest prevalence of stage 2 HTN was noted with the AAP-CPG (1.5%) and ESH (0.8%), respectively. The highest to lowest predictive abilities belonged to the 4th report, ESH, and AAP-CPG, respectively.
Meaning: Among the various definitions of pediatric HTN, the 4th report offered the best ability to predict a high CIMT during early adulthood, followed by the ESH and AAP-CPG.

Construction and validation of predictive models for intravenous immunoglobulin–resistant Kawasaki disease using an interpretable machine learning approach   (3,094 times)
Linfan Deng, Jian Zhao, Ting Wang, Bin Liu, Jun Jiang, Peng Jia, Dong Liu, Gang Li
Clin Exp Pediatr. 2024;67(8):405-414.   Published online July 23, 2024
Question: Is there a reliable model to predict intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD)?
Finding: We constructed 5 machine learning models to predict IVIG-resistant KD. Extreme gradient boosting (XGBoost) model was superior to logistic, support vector machine, light gradient boosting machine and multiple layers perception models. The SHAP (SHapley Additive exPlanations) value interpreted the contribution of each feature in XGBoost model.

Seroprevalence of maternal peripartum human T-cell lymphotropic virus type-1 infection: a systematic review and meta-analysis of the Nigerian literature   (2,847 times)
Abdulrasheed Usman, Muhammad Hamis Musa, Bukhari Isah Shuaib, Olayemi Balogun, Mukhtar Adeiza
Clin Exp Pediatr. 2023;66(7):307-316.   Published online December 22, 2022
The peripartum period is an important transmission time for human T-cell lymphotropic virus-1 (HTLV-1) infection, mainly via breastfeeding and partly through the placental tissues of carrier mothers. Although most HTLV-1–infected individuals are asymptomatic, fetal and childhood infections often result in several diseases with disappointing treatment outcomes. An estimated HTLV-1 burden in Nigeria among perinatal women must be determined to enable rational planning of a comprehensive health care intervention.

Clin Exp Pediatr. 2023;66(11):485-492.   Published online October 24, 2023
Question: Would students with reading disorder have a significantly higher prevalence of attention-deficit/hyperactiveimpulsive disorder (ADHD) symptoms than neurotypical students?
Finding: Students at risk of reading disorder exhibited significant ADHD symptoms compared with those not at risk of reading disorder according to all presentations of teacher assessments versus only for predominantly inattentive presentations of the parental assessments.
Meaning: Students with reading disorder have a significantly higher prevalence of ADHD symptoms than neurotypical students. Sex, parental education level, average family income, and children’s school affiliation significantly influenced reading disorder prevalence.

Trends in food allergen immunotherapy in Korea after changed national regulations   (2,785 times)
Tae Won Song
Clin Exp Pediatr. 2024;67(4):201-202.   Published online November 21, 2023
National regulations, academic guidelines, and clinical trends in food allergen immunotherapies (FA-AIT) differ among countries and have changed rapidly. Current officially approved FA-AIT are oral immunotherapy (OIT) using heated milk/egg in Korea and peanut OIT using standardized products in the United States and Europe. FA-AIT should be administered by specialist physicians with experience administering oral food challenge tests and managing severe allergic reactions inside and outside research settings.
