Complications of the Bacillus Calmette-Guerin vaccine as an early warning sign of inborn errors of immunity: a report of 197 patients.

Background: According to the WHO's recommendation for developing countries, Bacillus Calmette-Guerin (BCG) vaccination has been implemented in some countries as part of national vaccination programs at birth. Although it is generally considered safe, some complications may occur; including BCGitis (local) or BCGosis (systemic), ranging from mild like local abscesses to fatal impediments like osteomyelitis and disseminated BCG infection. This study aimed to determine the spectrum of inborn errors of immunity (IEI) in BCG-vaccinated neonates experiencing local or systemic complications.

Interferon therapy in alpha and Delta variants of SARS-CoV-2: The dichotomy between laboratory success and clinical realities.

The COVID-19 pandemic has caused significant morbidity and mortality worldwide. The emergence of the Alpha and Delta variants of SARS-CoV-2 has led to a renewed interest in using interferon therapy as a potential treatment option. Interferons are a group of signaling proteins produced by host cells in response to viral infections.

Clinical and genetic characterization of a progressive RBL2-associated neurodevelopmental disorder.

Retinoblastoma (RB) proteins are highly conserved transcriptional regulators that play important roles during development by regulating cell-cycle gene expression. RBL2 dysfunction has been linked to a severe neurodevelopmental disorder. However, to date, clinical features have only been described in six individuals carrying five biallelic predicted loss of function (pLOF) variants.

Association of NLRP3 single nucleotide polymorphisms with juvenile idiopathic arthritis: a case-control study.

Background: Although juvenile idiopathic arthritis (JIA) is one of the most common pediatric rheumatologic diseases, the exact etiology of JIA remains unclear. Genetic factors, including variations in the NLRP3 gene, have been implicated in the pathogenesis of autoimmune diseases. Therefore, we aimed to investigate the association between NLRP3 polymorphisms and JIA.

Misdiagnosed for 14 Years: Adenosine Deaminase 2 (ADA2) Deficiency in a Teen Mimicking Polyarteritis Nodosa.

The deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive disorder caused by loss of function mutations in the ADA2 gene (previously the CECR1 gene) on chromosome 22q11. The clinical spectrum of the disease is remarkably broad, and its presentations mimic features of polyarteritis nodosa, such as livedoid rash, hematological abnormalities (e.g.

Pediatric asthma and COVID-19 vaccination: unveiling patterns of hesitancy and acceptance.

Background: The global COVID-19 pandemic, declared in January 2020, necessitated urgent preventive measures, with vaccination as a key strategy. Despite progress in vaccine development and distribution, widespread hesitancy persists, impeding global disease control efforts. This study specifically explores COVID-19 vaccine hesitancy and acceptance among Iranian children with asthma, aiming to understand factors unique to this subgroup.

Effect of meal replacements formula on lipid profiles: A systematic review and meta-analysis of randomized controlled trials.

Background: Although some evidence shows the beneficial effects of meal replacements (MRs) on dyslipidaemias, it is not completely clear. Therefore, we investigate the possible effects of total and partial MRs on lipid profiles.

Methods: For this systematic review and meta-analysis, we searched MEDLINE, Web of Science, SCOPUS, and Embase.

Enhancing Late Retinopathy of Prematurity Outcomes with Fresh Bone Marrow Mononuclear Cells and Melatonin Combination Therapy.

Introduction: Retinopathy of prematurity (ROP) is a vasoproliferative disease affecting premature neonates with life-lasting impacts. This study aims to investigate the long-term functional outcomes and alterations in neural retina architecture following the intravitreal transplantation of bone marrow mononuclear cells (BMMNC) in the rat models of ROP, and to evaluate the effect of adjunctive therapy with melatonin.

Methods: 32 neonate rats were employed.

Sex Differences on the Pharmacokinetics of Drugs for Children with Chronic Kidney Disease: A Narrative Review.

Effective optimal pharmacotherapy requires a comprehensive understanding of the drug's pharmacokinetic properties. Chronic kidney disease (CKD) influences medication pharmacokinetics. However, whether sex differences exist in the pharmacokinetics of drugs for children with CKD is unknown.

Carbapenem resistance in gram-negative pathogens in an Iranian hospital: high prevalence of OXA-type carbapenemase genes.

Background: The widespread dissemination of carbapenem-resistant Gram-negative bacteria poses a significant threat to global public health.

Purpose: This study aimed to investigate the prevalence of carbapenem resistance in Gram-negative bacteria isolated from patients at the Children's Medical Center Hospital, Tehran, Iran, to understand the molecular mechanisms underlying this resistance.

Methods: During the period spanning from June 2019 to June 2020, 777 Gram-negative bacterial strains were isolated.

Nanomedicine marvels: crafting the future of cancer therapy with innovative statin nano-formulation strategies.

Statins, traditionally used for managing hyperlipidemia and cardiovascular diseases, have garnered significant interest for their potential anti-cancer properties. Research indicates that statins can inhibit critical processes in cancer development, such as apoptosis, angiogenesis, and metastasis. Despite their promising anti-cancer effects, the clinical application of statins in oncology has been hampered by their inherent low solubility and bioavailability.

LncRNA MALAT1 as diagnostic and prognostic biomarker in colorectal cancers: A systematic review and meta-analysis.

Objective: This study investigated the relationship between the long non-coding RNA Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1) expression and colorectal cancer (CRC) using a thorough systematic review and meta-analysis.

Methods: Under the PRISMA guidelines, a systematic review was conducted on studies published from the databases' inception to September 18, 2023. Prognostic value and diagnostic accuracy were explored.

Cancer Trends in Inborn Errors of Immunity: A Systematic Review and Meta-Analysis.

Background: Patients with inborn errors of immunity (IEI) are susceptible to developing cancer due to defects in the immune system. The prevalence of cancer is higher in IEI patients compared to the immunocompetent population and cancers are considered as an important and common cause of death in IEI patients.

Objectives: To systematically review demographic, genetic and cancer-related data of IEI patients with a history of malignancy.

Three cases of autoinflammatory disease with novel NLRC4 mutations, and the first mutation reported in the CARD domain of NLRC4 associated with autoinflammatory infantile enterocolitis (AIFEC).

Background: Gain of function (GOF) mutations in NOD-like receptor family CARD-containing 4 protein (NLRC4) gene induce a wide spectrum of autoinflammatory phenotypes. Currently, we categorize them into four groups: familial cold autoinflammatory syndrome (FCAS)4, autoinflammatory infantile enterocolitis (AIFEC), NLRC4-macrophage associated syndrome (MAS), and neonatal-onset multisystem inflammatory disease (NOMID). The rarity and complexity of the disease necessitate the description of new cases and a reexamination of our understanding of the condition.
