Differential diagnosis and comparison of diagnostic algorithms in children and adolescents with autoimmune encephalitis in Spain: a prospective cohort study and retrospective analysis.

Background: The usefulness of current diagnostic approaches in children with suspected autoimmune encephalitis is unknown. We aimed to assess the diagnosis of autoimmune encephalitis in clinical practice and to compare the performance of two international diagnostic algorithms (one intended for patients of any age [general], the other intended for paediatric patients), with particular emphasis on the evaluation of patients with probable antibody-negative autoimmune encephalitis because this diagnosis suggests that immunotherapy should be continued or escalated but is difficult to establish.

Methods: We did a prospective cohort study that included all patients (<18 years of age) with suspected autoimmune encephalitis recruited at 40 hospitals in Spain whose physicians provided clinical information every 6 months for 2 years or more.

Homozygous variant in translocase of outer mitochondrial membrane 7 leads to metabolic reprogramming and microcephalic osteodysplastic dwarfism with moyamoya disease.

Background: Impaired mitochondrial protein import machinery leads to phenotypically heterogeneous diseases. Here, we report a recurrent homozygous missense variant in the gene that encodes the translocase of outer mitochondrial membrane 7 (TOMM7) in nine patients with microcephaly, short stature, facial dysmorphia, atrophic macular scarring, and moyamoya disease from seven unrelated families.

Methods: To prove the causality of the TOMM7 variant, mitochondrial morphology, proteomics, and respiration were investigated in CRISPR/Cas9-edited iPSCs-derived endothelial cells.

UGT1A1 and BLVRA allele and genotype variants in neonatal patients with hyperbilirubinemia in southern China.

We explore the allele and genotype distribution of UGT1A1 and BLVRA variants in individuals affected by neonatal hyperbilirubinemia in southern China. Blood specimens were collected from 240 neonates: 126 cases of hyperbilirubinemia and 114 healthy controls. Serum levels of total protein, albumin, bilirubin (total and direct), urea nitrogen, creatinine, and other biochemical parameters were quantified using a biochemical analyzer.

Predictors for spontaneous remission in childhood chronic immune thrombocytopenia.

This study examined the factors associated with spontaneous remission in children with chronic immune thrombocytopenia (ITP). We retrospectively analyzed the medical records of patients diagnosed with ITP from January 1988 to December 2019 at our institute. A total of 104 children with chronic ITP were identified.

Risk factors and disease trajectories of recurrent immune thrombocytopenia in children.

This retrospective study aimed to analyse the course and outcome of recurrent immune thrombocytopenia (ITP) in children and to identify factors associated with recurrence. A total of 497 newly diagnosed ITP children with platelet <30 × 10/L between January 1988 and December 2019 were included. Recurrent ITP was defined as a new event of thrombocytopenia after at least 3 months of remission without treatment.

Exploring noninvasive matrices for assessing long-term exposure to phthalates: a scoping review.

The phthalic acid esters (PAEs) are one class of the most abundant and frequently studied pseudo-persistent organic pollutants. Noninvasive urine is an effective substrate for evaluating PAE exposure, but repeated sampling is needed to overcome this bias. This adds much work to on-site collection and the cost of detection increases exponentially.

Health hazards of preconception phthalate exposure: A scoping review of epidemiology studies.

There is a close relationship between preconception health and maternal and child health outcomes, and the consequences may be passed down from generation to generation. In 2018, Lancet published three consecutive articles emphasizing the importance of the preconception period. Phthalic acid ester (PAE) exposure during this period may affect gametogenesis and epigenetic information in gametophytes, thereby affecting embryonic development and offspring health.

The developmental phenotype of motor delay in extremely preterm infants following early-life respiratory adversity is influenced by brain dysmaturation in the parietal lobe.

Background: Research indicates that preterm infants requiring prolonged mechanical ventilation often exhibit suboptimal neurodevelopment at follow-up, coupled with altered brain development as detected by magnetic resonance imaging (MRI) at term-equivalent age (TEA). However, specific regions of brain dysmaturation and the subsequent neurodevelopmental phenotype following early-life adverse respiratory exposures remain unclear. Additionally, it is uncertain whether brain dysmaturation mediates neurodevelopmental outcomes after respiratory adversity.

Very Long-Term Functional Outcomes and Dependency in Children With Anti-NMDA Receptor Encephalitis.

Objectives: To assess the daily function of children with anti-N-methyl-d-aspartate receptor encephalitis (NMDARe) after a minimal follow-up of 5 years.

Methods: Patients 18 years and younger by the time of disease onset, whose serum and CSF were studied in our center between 2013 and 2017, were included in the study. Patients' daily life function was assessed by their physicians using a 15-domain question format (Liverpool Outcome Score).

MOG Antibodies Restricted to CSF in Children With Inflammatory CNS Disorders.

Objectives: To assess the clinical significance of myelin oligodendrocyte glycoprotein antibodies (MOG-abs) restricted to CSF in children with inflammatory CNS disorders.

Methods: Patients included 760 children (younger than 18 years) from 3 multicenter prospective cohort studies: (A) acquired demyelinating syndromes, including acute disseminated encephalomyelitis (ADEM); (B) non-ADEM encephalitis; and (C) noninflammatory neurologic disorders. For all cases, paired serum/CSF samples were systematically examined using brain immunohistochemistry and live cell-based assays.

Association of Neonatal Antibiotic Exposure with Long-Term Growth Trajectory Faltering in Preterm-Birth Children.

Introduction: Preterm neonates often receive a variety of duration of antibiotic exposure during admission. The aim of the study was to evaluate whether neonatal antibiotic exposure is relevant with longitudinal growth problems in preterm-birth children.

Methods: This prospective study enrolled 481 infants who were born <32 weeks of gestation, discharged, and longitudinally followed from corrected age (CA) 6-60 months.

The Quartile Levels of Thyroid-stimulating Hormone at Newborn Screening Stratified Risks of Neurodevelopmental Impairment in Extremely Preterm Infants: A Population Cohort Study.

Background: To evaluate whether thyroid-stimulating hormone (TSH) measured during newborn screening (NBS) at birth and at discharge can be surrogate markers for neurodevelopmental impairment (NDI) in extremely preterm infants.

Methods: The population cohort enrolled infants born <29 weeks' gestation in 2008-2020 in southern Taiwan. Infants with a maternal history of thyroid disorders and infants who required thyroxine supplementation during hospitalization were excluded.

Antibody Investigations in 2,750 Children With Suspected Autoimmune Encephalitis.

Objectives: To assess the frequency and types of neuronal and glial (neural) antibodies in children with suspected autoimmune encephalitis (AE).

Methods: Patients younger than 18 years with suspected AE other than acute disseminated encephalomyelitis, whose serum or CSF samples were examined in our center between January 1, 2011, and April 30, 2022, were included in this study. Samples were systematically examined using brain immunohistochemistry; positive immunostaining was further investigated with cell-based assays (CBA), immunoblot, or live neuronal immunofluorescence.

Alleviative Effect of Extract on Peripheral Neuropathy in Ovariectomized Diabetic Mice.

In diabetes mellitus, has been reported to ameliorate blood sugar levels and inhibit inflammation through its polyphenol and flavonoid contents. However, its effect on diabetic peripheral neuropathy (DPN) remains unknown. This study aimed to investigate the effect of extract (FFE) on DPN in ovariectomized diabetic mice.

Associating phthalate exposure during pregnancy with preschooler's FMI, ABSI and BRI trajectories via putative mechanism pathways.

Phthalates are well-known obesogens, but a few studies have explored their impacts on the childhood fat mass index (FMI), body shape index (ABSI) and body roundness index (BRI). Information from 2950 participants recruited in the Ma'anshan Birth Cohort was analyzed. The relationships between six maternal phthalate metabolites and their mixture and childhood FMI, ABSI and BRI were investigated.

Neonicotinoid Imidacloprid Affects the Social Behavior of Adult Zebrafish by Damaging Telencephalon Neurons through Oxidation Stress, Inflammation, and Apoptosis.

The neonicotinoid imidacloprid is a widely used insecticide worldwide. We assessed the effects of acute and chronic imidacloprid exposure on the social behavior of adult zebrafish. We assembled simple apparatus to detect 2D locomotion: a single camera capture system and two specially designed water tanks.

The associations between prenatal phthalate exposure and childhood glycolipid metabolism and blood pressure: An updated systematic review and a pilot meta-analysis of prospective cohort studies.

This is the first pilot meta-analysis on the association of prenatal phthalate exposure with childhood cardiometabolic risks. A systematic literature search was performed in MEDLINE, Web of Science and CNKI (Chinese National Knowledge Infrastructure) until June 5, 2023. A total of seven studies with 5746 children (2646 girls and 3100 boys) were finally included.

B7-H3 but not PD-L1 is involved in the antitumor effects of Dihydroartemisinin in non-small cell lung cancer.

Dihydroartemisinin (DHA), an active antimalaria metabolite derived from artemisinin, has received increasing attention for its anticancer activities. However, little is known about the anticancer mechanisms of DHA, although the existing data define its antimalaria effects by producing excessive reactive oxygen species (ROS). In this study, we showed that DHA effectively suppresses in vitro and in vivo tumor growth of non-small cell lung cancer (NSCLC) without perceptible toxicity on heart, liver, spleen, lung, and kidney tissues.

Associations between Early Thyroid-Stimulating Hormone Levels and Morbidities in Extremely Preterm Neonates.

Introduction: High-end cutoffs of thyroid-stimulating hormone (TSH) have been emphasized for hypothyroidism therapy in extremely preterm infants, but the significance of low TSH levels remains unknown. This study hypothesized that the spectrum of TSH levels by newborn screening after birth signifies specific morbidities in extremely preterm neonates.

Methods: The multicenter population cohort analyzed 434 extremely preterm neonates receiving TSH screening at 24-96 h of age in 2008-2019.

Predictors of Remission in Severe Childhood Immune Thrombocytopenia.

Childhood immune thrombocytopenia (ITP; platelet count < 100 × 10/L) is the most common bleeding disorder in children. A total of 3-5% of children with ITP face a greater risk of bleeding, resulting in significant morbidity and mortality. Childhood ITP is often benign and self-limited; however, children with severe ITP (platelet count < 30 × 10/L) require investigation and monitoring.
