Pharmacogenomics polygenic risk score: Ready or not for prime time?

Pharmacogenomic Polygenic Risk Scores (PRS) have emerged as a tool to address the polygenic nature of pharmacogenetic phenotypes, increasing the potential to predict drug response. Most pharmacogenomic PRS have been extrapolated from disease-associated variants identified by genome wide association studies (GWAS), although some have begun to utilize genetic variants from pharmacogenomic GWAS. As pharmacogenomic PRS hold the promise of enabling precision medicine, including stratified treatment approaches, it is important to assess the opportunities and challenges presented by the current data.

Continuous Infusion of Dexmedetomidine for Maintenance of Sedation in an Aggressive Adolescent with Autism Spectrum Disorder in the Emergency Department.

Background: The treatment of aggressive behavior and agitation in pediatric patients with autism spectrum disorder (ASD) in the emergency department is topical and challenging.

Case Presentation: We described an adolescent with autism spectrum disorder treated ten times in the pediatric emergency department for severe episodes of aggressiveness and agitation. After resolving the acute phase of these behavioural crises, sedation was maintained with a continuous infusion of dexmedetomidine to prevent the resurgence of agitation and to organize discharge properly, considering the family's needs.

Preanalytical Stability of 13 Antibiotics in Biological Samples: A Crucial Factor for Therapeutic Drug Monitoring.

The stability of antibiotic preanalytical samples is a critical factor in therapeutic drug monitoring (TDM), a practice of undoubted importance for the proper therapeutic use of antibiotics, especially in complex management patients, such as pediatrics. This review aims to analyze the data in the literature regarding the preanalytical stability of some of the antibiotics for which TDM is most frequently requested. The literature regarding the preanalytical stability of amikacin, ampicillin, cefepime, ceftazidime, ciprofloxacin, daptomycin, gentamicin, levofloxacin, linezolid, meropenem, piperacillin, teicoplanin, and vancomycin in plasma, serum, whole blood, and dried blood/plasma spot samples was analyzed.

Multiplex array analysis of circulating cytokines and chemokines in COVID-19 patients during the first wave of the SARS-CoV-2 pandemic in Milan, Italy.

Background: The systemic inflammatory syndrome called "cytokine storm" has been described in COVID-19 pathogenesis, contributing to disease severity. The analysis of cytokine and chemokine levels in the blood of 21 SARS-CoV-2 positive patients throughout the phases of the pandemic has been studied to understand immune response dysregulation and identify potential disease biomarkers for new treatments. The present work reports the cytokine and chemokine levels in sera from a small cohort of individuals primarily infected with SARS-CoV-2 during the first wave of the COVID-19 pandemic in Milan (Italy).

An ecological study shows increased prevalence of autism spectrum disorder in children living in a heavily polluted area.

The burden of autism spectrum disorder (ASD) is increasing worldwide with genetic, epigenetic, and environmental factors being possibly responsible for the observed epidemiological figures. In the setting of environmental exposure, the city of Taranto, in Southern Italy, represents an interesting case study as it hosts well inside the city one of the biggest steel plants in Europe. This is a cross-sectional ecological study carried out in the year 2020 in the province of Taranto designed to estimate the burden of ASD in the municipalities of Taranto and Statte, classified as high environmental risk areas (Contaminated Site of National Interest-SIN), compared to the other 27 municipalities of the same province.

Cerebral Synchronization Between Mothers and Their Newborns During Breastfeeding.

Breastfeeding is a fundamental biological function in mammals, allowing the progeny to develop in a physiological way. A physical and emotional dialog between mothers and offspring during breastfeeding has been described as part of the attachment relationship, and a synchronicity between maternal and neonatal brains can be hypothesized. This study aimed to assess if neonatal and maternal cortical areas activated during breastfeeding are functionally synchronized since the second day of life.

Interleukin-1 blockade in patients with Wiskott-Aldrich syndrome: a retrospective multinational case series.

Up to 70% of patients with Wiskott-Aldrich syndrome (WAS) develop autoimmune and inflammatory manifestations. Dysregulation of interleukin 1 (IL-1) may be involved in their pathogenesis, yet there is little evidence on treatment with anti-IL-1 agents in these patients. We conducted a multicenter retrospective analysis of 9 patients with WAS treated with anti-IL-1 agents (anakinra or canakinumab).

Infantile and Very Early Onset Inflammatory Bowel Disease: A Multicenter Study.

Objectives: This study described disease characteristics and long-term outcomes in patients diagnosed with very early onset inflammatory bowel disease (VEOIBD) (diagnosed before 6 years of age) and infantile-IBD (before 2 years).

Methods: Cases from 21 centers worldwide diagnosed with VEOIBD (2008-2018), with minimum 2 years of follow-up, were retrospectively reviewed.

Results: The cohort included 243 patients (52% males, median follow-up of 5.

Performance of 16S rRNA Gene Next-Generation Sequencing and the Culture Method in the Detection of Bacteria in Clinical Specimens.

Effective treatment of infectious diseases requires prompt and accurate bacterial identification and tailored antimicrobial treatments. Traditional culture methods are considered the gold standard, but their effectiveness diminishes for fastidious and hard-to-grow microorganisms. In recent years, molecular diagnostic tools such as 16S rRNA gene next-generation sequencing (16S NGS) have gained popularity in the field.

Effect of early post-hematopoietic stem cell transplant tacrolimus concentration on transplant outcomes in pediatric recipients: One facility's ten-year experience of immunosuppression with tacrolimus.

Acute graft-versus-host disease (GVHD) is a common life-threatening complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), ranking as the second leading cause of death among recipients, surpassed only by disease relapse. Tacrolimus is commonly used for GVHD prophylaxis, but achieving therapeutic blood levels is challenging, particularly in pediatrics, due to the narrow therapeutic window and the high interindividual variability. The retrospective study conducted at IRCCS "Burlo Garofolo" in Italy aimed to assess the impact of early post-HSCT tacrolimus levels on transplant-related outcomes in pediatric recipients.

The Italian Consensus Conference on the role of rehabilitation for children and adolescents with leukemia, central nervous system tumors, and bone cancer, part 2: general principles for the rehabilitation treatment of motor function impairments.

In Italy, 1400 children and 800 adolescents are diagnosed with cancer every year. About 80% of them can be cured but are at high risk of experiencing severe side effects, many of which respond to rehabilitation treatment. Due to the paucity of literature on this topic, the Italian Association of Pediatric Hematology and Oncology organized a Consensus Conference on the role of rehabilitation of motor impairments in children/adolescents affected by leukemia, central nervous system tumors, and bone cancer to state recommendations to improve clinical practice.

Systematic review of the complement components as potential biomarkers of pre-eclampsia: pitfalls and opportunities.

Unlabelled: The complement system (C) is a crucial component of the innate immune system. An increasing body of research has progressively shed light on the pivotal role of C in immunological tolerance at the feto-maternal interface. Excessive C activation or impaired C regulation may determine the onset of pregnancy-related pathological conditions, including pre-eclampsia (PE).

Vertical Parasagittal Hemispherotomy in a Pediatric Case of Epilepsy Due to Rasmussen Encephalitis: 2-Dimensional Operative Video.

Hemispherotomy is an effective disconnection technique for the treatment of different forms of drug-resistant epilepsy due to encephalopathies with unilateral hemispheric involvement.1-8 We describe the case of a 6-year-old child affected by Rasmussen encephalitis who underwent right vertical parasagittal hemispherotomy.9 The goal of the procedure was to isolate the basal ganglia region by interrupting the interhemispheric and intrahemispheric white matter connectivity.

Successful treatment of cortical visual impairment in children using anti-amblyopia treatment despite the absence of amblyopia: a case report.

Background: Cortical visual impairment (CVI) is a verifiable visual dysfunction that cannot be attributed to disorders of the anterior visual pathways or any potentially co-occurring ocular impairment. Given the limited knowledge on the most effective interventions for visual impairment resulting from CVI, this case report provides valuable insights into an example of successful implementation of anti-amblyopia therapy in a patient with CVI.

Case Presentation: This case report presents a 5-year-old girl with CVI secondary to hypoxic-ischemic injury, resulting in visual impairment, dyspraxia, and abnormal visual evoked potential testing.

Translation and cultural adaptation of the Italian version of the Paediatric Palliative Screening Scale.

Unlabelled: The number of children eligible for Paediatric Palliative Care has dramatically increased over the years, with few tools that can help with early identification. The Paediatric Palliative Screening Scale is a dedicated German, English, and Portuguese screening tool. We aimed to translate and perform a cultural adaptation to the Italian setting of the Paediatric Palliative Screening Scale.

Siglec-1, an easy and contributory inflammation marker in rheumatology.

Objectives: Inflammatory markers such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are poorly informative about interferon (IFN)-related disorders. In these conditions, the measure of the interferon score (IS), obtained by measuring the expression of IFN-stimulated genes, has been proposed. Flow cytometry-based assays measuring sialic-acid-binding Ig-like lectin 1 (Siglec-1) expression could be a more practical tool for evaluating IFN-inflammation.
