Neural correlates of irritability in a community sample of children.

J Affect Disord 2021 Jun 5;292:223-226. Epub 2021 Jun 5.

Murdoch Children's Research Institute, Melbourne, Australia; Department of Paediatrics, University of Melbourne, Melbourne, Australia; School of Psychology, Deakin University, Geelong, Australia.

Irritability has been associated with aberrant patterns of neural activation, yet little is known about structural brain correlates of irritability. As such, we aimed to investigate associations between irritability and gray matter volume (GMV) in a community sample of children enriched for irritability. The sample comprised children (n=162) aged 9-11 years with and without Attention-Deficit/Hyperactivity Disorder (ADHD), participating in a cohort study with magnetic resonance imaging data available.

Maternal posttraumatic stress and FKBP5 Genotype interact to predict trauma-related symptoms in preschool-age offspring.

J Affect Disord 2021 May 26;292:212-216. Epub 2021 May 26.

Department of Psychiatry, University of Connecticut School of Medicine, Farmington, CT, United States. Electronic address:

Background: Children of parents with posttraumatic stress (PTS) face heightened risk for developing emotional and behavioral problems, regardless of whether they experience a traumatic event themselves. The current study investigates whether child FKBP5, a stress relevant gene shown to interact with child trauma exposure to increase risk for PTS, also moderates the well-established link between maternal PTS and child symptoms.

Methods: Data are derived from a longitudinal lab-based study for which 205 dyads of trauma-exposed mothers and their preschool-age children from a sample enriched for violence exposure provided DNA samples and completed measures of maternal and child trauma-related symptoms. Read More

Everyday interactions support toddlers' learning of conventional actions on artifacts.

J Exp Child Psychol 2021 Jun 12;210:105201. Epub 2021 Jun 12.

Department of Psychology, University of Chicago, Chicago, IL 60637, USA.

Children learn to perform actions on artifacts in their environments from infancy, but the ways caregivers support this learning during everyday interactions are relatively unexplored. This study investigated how naturalistic caregiver-child teaching interactions promoted conventional action learning in toddlers. Caregivers of 32 24- to 26-month-old children taught their children to perform novel target actions on toys. Read More

Hum Vaccin Immunother 2021 Jun 15:1-6. Epub 2021 Jun 15.

Serum Institute of India Pvt Ltd, Pune, India.

Currently, most licensed vaccines against SARS-CoV-2 infection are approved for adults and not for children.

Parent responsiveness mediates the association between hyporeactivity at age 1 year and communication at age 2 years in children at elevated likelihood of ASD.

Autism Res 2021 Jun 15. Epub 2021 Jun 15.

Program for Early Autism Research, Leadership, and Service (PEARLS), University of North Carolina, Chapel Hill, North Carolina, USA.

Studies suggest that higher parent responsiveness is associated with higher child language abilities. Infants and toddlers later diagnosed with autism spectrum disorder (ASD) often display hyporeactivity to sensory stimuli, which has also been associated with lower child communication abilities and lower parent responsiveness. Yet, whether parent responsiveness mediates the relationship between child hyporeactivity and later communication outcomes remains unexplored. Read More

The effect of congenital blindness on resting-state functional connectivity revisited.

Sci Rep 2021 Jun 14;11(1):12433. Epub 2021 Jun 14.

Biological Psychology and Neuropsychology, Institute for Psychology, University of Hamburg, Von-Melle-Park 11, 20146, Hamburg, Germany.

Lower resting-state functional connectivity (RSFC) between 'visual' and non-'visual' neural circuits has been reported as a hallmark of congenital blindness. In sighted individuals, RSFC between visual and non-visual brain regions has been shown to increase during rest with eyes closed relative to rest with eyes open. To determine the role of visual experience on the modulation of RSFC by resting state condition-as well as to evaluate the effect of resting state condition on group differences in RSFC-, we compared RSFC between visual and somatosensory/auditory regions in congenitally blind individuals (n = 9) and sighted participants (n = 9) during eyes open and eyes closed conditions.

Effect of Perinatal Vitamin D Deficiency on Lung Mesenchymal Stem Cell Differentiation and Injury Repair Potential.

Am J Respir Cell Mol Biol 2021 Jun 14. Epub 2021 Jun 14.

The Lundquist Institute, 117316, Pediatrics, Torrance, California, United States;

Stem cells, including resident lung mesenchymal stem cells (LMSCs), are critically important for injury repair. Compelling evidence links perinatal vitamin D (VD) deficiency to reactive airway disease; however, the effects of perinatal VD deficiency on LMSC function is unknown. We tested the hypothesis that perinatal VD deficiency alters LMSC proliferation, differentiation, and function, leading to an enhanced myogenic phenotype. Read More

Maternal age at first childbirth and geographical variation in HBV prevalence in Cameroon: Important role of mother-to-child transmission.

Clin Infect Dis 2021 Jun 14. Epub 2021 Jun 14.

Unité d'Épidémiologie des Maladies Émergentes, Institut Pasteur, Paris, France.

Background: The prevalence of hepatitis B virus (HBV) infection varies geographically around the world. However, the underlying reasons for this variation are unknown. Using a nationally representative population-based sample from all 58 administrative divisions in Cameroon, we examined the association between median maternal age at first childbirth in a preceding generation, a proxy for the frequency of mother-to-child transmission (MTCT) of HBV in a region, and the risk of chronic HBV infection, defined as positive surface antigen (HBsAg), in the index generation.

Developing Empirical Latent Profiles of Impulsive Aggression and Mood in Youths across Three Outpatient Samples.

J Clin Child Adolesc Psychol 2021 Jun 14:1-16. Epub 2021 Jun 14.

Department of Psychiatry, Virginia Commonwealth University.

: Aggression with impulsivity and reactivity (AIR) may distinguish a subset of youth from those with attention problems, rule-breaking behavior, or mood disorders, potentially with differential treatment response. Yet, DSM-5 and ICD-10 do not include an AIR diagnosis. Thus, we empirically grouped youths into profiles based on AIR, manic, depressive, rule-breaking, and self-harm behaviors; examined which profiles replicated across three samples; and characterized profile sets on demographic and clinical features.

The influence of individual characteristics and non-respiratory diseases on blood eosinophil count.

Clin Transl Allergy 2021 Jun 3;11(4):e12036. Epub 2021 Jun 3.

Department of Women's and Children's Health Paediatric Research Uppsala University Uppsala Sweden.

Background: Blood eosinophil (B-Eos) count is an emerging biomarker in the management of respiratory disease but determinants of B-Eos count besides respiratory disease are poorly described. Therefore, we aimed to evaluate the influence of non-respiratory diseases on B-Eos count, in comparison to the effect on two other biomarkers: fraction of exhaled nitric oxide (FeNO) and C-reactive protein (CRP), and to identify individual characteristics associated with B-Eos count in healthy controls.

Methods: Children/adolescents (<18 years) and adults with complete B-Eos data from the US National Health and Nutritional Examination Surveys 2005-2016 were included, and they were divided into having respiratory diseases ( = 3333 and  = 7,894, respectively) or not having respiratory disease ( = 8944 and  = 15,010, respectively).

Metabolomic Characterization of Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS).

Front Neurosci 2021 28;15:645267. Epub 2021 May 28.

Child and Adolescent Neuropsychiatry Unit, Department of Biomedical Sciences, University of Cagliari, Cagliari, Italy.

Introduction: PANS is a controversial clinical entity, consisting of a complex constellation of psychiatric symptoms, adventitious changes, and expression of various serological alterations, likely sustained by an autoimmune/inflammatory disease. Detection of novel biomarkers of PANS is highly desirable for both diagnostic and therapeutic management of affected patients. Analysis of metabolites has proven useful in detecting biomarkers for other neuroimmune-psychiatric diseases. Read More
