Background: Recent proteomic studies have documented that Long COVID in adults is characterized by a pro-inflammatory signature with thromboinflammation. However, if similar events happen also in children with Long COVID has never been investigated.

Methods: We performed an extensive protein analysis of blood plasma from pediatric patients younger than 19 years of age Long COVID and a control group of children with acute COVID-19, MIS-C, and healthy controls resulted similar for sex distribution and age.

Introduction: Central nervous system (CNS) infections represent some of the most critical pediatric health challenges, characterized by high mortality rates and a notable risk of long-term complications. Despite their significance, standardized guidelines for endocrinological follow-up of CNS infection survivors are lacking, leading to reliance on the expertise of individual centers and clinicians.

Materials And Methods: Prospective monocentric observational study conducted at the Fondazione Policlinico Universitario Agostino Gemelli in Rome, Italy.

: Respiratory viral infections (RVIs) exhibit seasonal patterns influenced by biological, ecological, and climatic factors. Weather variables such as temperature, humidity, and wind impact the transmission of droplet-borne viruses, potentially affecting disease severity. However, the role of climate in predicting complications in pediatric RVIs remains unclear, particularly in the context of climate-change-driven extreme weather events.

We provide preliminary evidence that, also in children, Long coronavirus disease (COVID) may be characterized by a proinflammatory signature. Ten Long COVID patients, 7 convalescent subjects after COVID infection and 4 healthy controls were enrolled. When adjusted for sex, children with long COVID had statistically significant differences in the levels of Flt3L, CD5, uPA, CCL23, CD40 and TGFα.

Article Synopsis
  • A study conducted in Rome, Italy, aimed to investigate the long-term outcomes and predictors of Long Covid in children aged 0-18 who had confirmed SARS-CoV-2 infections, assessing them at various intervals up to 36 months post-infection.
  • The findings revealed that approximately 23.2% of the children were diagnosed with Long Covid by 3-6 months, with significant risk factors including age over 12, presence of comorbidities, infection with original variants, and being female.
  • Vaccination was found to reduce the risk of developing Long Covid and reinfections, particularly in older children, while infection with earlier SARS-CoV-2 variants was linked to longer durations of Long Covid symptoms.

Article Synopsis
  • Recent increases in migration have led to more unaccompanied foreign minors (UFMs) entering Italy, prompting the need for accurate age assessments by pediatricians, guided by updated 2020 protocols that prioritize minors' well-being.
  • A survey of 344 Italian pediatricians revealed that only 38.9% have conducted age assessments, with only 14.2% fully knowledgeable about the procedures, while many others had limited or no knowledge.
  • There is a noted gap in awareness and resources regarding a multidisciplinary approach to age estimation, indicating a need for better education and resource allocation to assist UFMs and enhance healthcare practices.

We investigated if children with Long COVID (n=14) have activated platelets compared with healthy controls (n=14). Platelet activation and secretion markers were investigated by flow cytometry using MoAbs directed against P-selectin, CD63, and PAC-1 in quiescent platelets and in platelets stimulated with 10-µM adenosine diphosphate and 25-µM protease activated receptor 1-activating peptide. Circulating platelets of patients with Long COVID had significantly increased expression of the activation marker cytometry using MoAbs directed against P-selectin ( P = 0.

Background: Toxoplasmosis is a parasitic infection caused by Toxoplasma gondii and is responsible for gestational and congenital infections worldwide. The current standard therapy is based on the administration of Spiramycin to prevent trans-placental transmission. Other therapies are being studied to reduce the rates of foetal transmission and symptomatic congenital infection.

Background: Nowadays children live in a digital world, exposed to relevant risks for their health and safety. The aim of this study is to investigate the use of multimedia devices in a sample of children and adolescents.

Methods: The study was performed between November 2018 and June 2019 in a third-level University Hospital, recruiting children and adolescents during general or specialistic follow-up visits.

We performed this study to evaluate factors associated with antibiotic prescriptions in children with adenovirus infection, since no studies have attempted to address this aspect in the pediatric population. Retrospective study of children younger than 18 years of age tested positive for adenovirus on a syndromic nasopharyngeal test from 2018 to 2023. We compared the need of pediatric intensive care unit (PICU), invasive ventilation, and other respiratory support, viral etiologies, clinical presentations, imaging, and laboratory results in the precovid (2018-2019) and covid (2020-2022) period.

Background: Cardiopulmonary exercise testing (CPET) is a noninvasive and nonexpensive diagnostic tool, that provides a comprehensive evaluation of the pulmonary, cardiovascular, and skeletal muscle systems' integrated reactions to exercise. CPET has been extensively used in adults with Long COVID (LC), while the evidence about its role in children with this condition is scarce.

Methods: Prospective, case-controlled observational study.

Introduction: Procalcitonin and presepsin have been suggested to be able to discriminate bacterial and viral infections, also in children. This scoping review aims to better explore the available evidence around the potential role of these biomarkers in the subgroup of children with respiratory infectious diseases.

Methods: We performed a systematic scoping review of studies published until March 2023 in the following bibliographic databases: PubMed, EMBASE, Cochrane and SCOPUS.

Fever is among the most common reason for medical assessment and antibiotic prescription in practice. The aim of this study was to evaluate positive and negative predictive values of rapid nasopharyngeal swabs for respiratory pathogens to discriminate viral from bacterial infections. We prospectively tested children with signs and/or symptoms of infections (e.

Severe plasmodium falciparum infection can induce respiratory distress and clinical ARDS in children, requiring intensive care admission and respiratory support. We present 3 cases of imported malarial acute respiratory distress syndrome requiring noninvasive ventilation in the pediatric intensive care unit, in the absence of any cerebral involvement. Radiological features and their relationship with severe hematological complications are also illustrated.

By exploring real-life management of children diagnosed with PPCC, the International Post-COVID-Condition in Children Collaboration (IP4C) aimed to provide guidance for future PPCC care.

Methods: We performed a cross-sectional international, multicenter study on used PPCC definitions; the organization of PPCC care programs and patients characteristics.

We aimed to investigate if children with their first UTI and a concomitant positive blood culture have a higher risk of abnormalities. We performed a retrospective study of children younger than 18 years of age with their first UTI. Multivariate logistic regression and receiver operating characteristic (ROC) curves were used to evaluate if positive blood cultures are associated with urinary abnormalities.

Unlabelled: Currently, it remains unclear why some children develop invasive group A Streptococcus (iGAS) and how to manage this condition. Therefore, to explore available works in the literature, we performed a scoping review aiming to analyze the current literature on clinical presentation of different illnesses outcomes of iGAS, with a specific focus on predictors of invasive infection, including an assessment of the prodromal stages of the disease and the possible presence of previous non-invasive GAS infections in children that later developed iGAS.

Methods: We conducted a systematic search on PubMed and SCOPUS of all pediatric studies reporting iGAS cases, following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist.
