The Dynamic Interaction Between Psychological Health and Sleep Symptoms Following Adolescent Concussion.

Objectives: To evaluate changes in psychological symptoms and sleep quality at three clinically relevant milestones following adolescent concussion: while symptomatic, at symptom resolution, and about 2 months after symptom resolution.

Study Design: We conducted a secondary analysis of a multisite, longitudinal investigation of adolescent concussion recovery. Participants enrolled < 21 days following concussion and completed self-report questionnaires (Patient-Reported Outcomes Measurement Information System [PROMIS] Pediatric Global 25 anxiety and depressive symptom domains, and the Pittsburgh Sleep Quality Index [PSQI]) at three time points: visit 1 (symptomatic), visit 2 (<14 days after symptom resolution), and visit 3 (2 months after symptom resolution).

Factors Influencing Parental Decisions on Respiratory Syncytial Virus Immunoprophylaxis.

Objectives: New respiratory syncytial virus (RSV) immunizations for infants and pregnant mothers recently became available to prevent severe RSV disease in infants. We aimed to determine the primary reasons for parental RSV immunization decisions. We further sought to evaluate the associations between vaccine receipt and source of health care information and trust in one's health care provider.

A human iPSC-derived midbrain neural stem cell model of prenatal opioid exposure and withdrawal: A proof of concept study.

A growing body of clinical literature has described neurodevelopmental delays in infants with chronic prenatal opioid exposure and withdrawal. Despite this, the mechanism of how opioids impact the developing brain remains unknown. Here, we developed an in vitro model of prenatal morphine exposure and withdrawal using healthy human induced pluripotent stem cell (iPSC)-derived midbrain neural progenitors in monolayer.

Anti-miR oligo-mediated detection of human salivary microRNAs for mild traumatic brain injury.

Mild traumatic brain injury (mTBI), often resulting from traffic accidents, workplace incidents, sports, or recreational activities, is a neurological condition that significantly impacts the daily lives of many individuals. The absence of reliable biomarkers and the non-specific nature of mTBI symptoms pose challenges for accurate diagnosis, leading to undetected cases and potential long-term consequences. Current diagnostic approaches, including neuroimaging, serum biomarkers, and cognitive assessments, suffer from cost, invasiveness, and sensitivity limitations.

Association of Longitudinal Oral Microbiome Activity and Pediatric Concussion Recovery.

Mild traumatic brain injury (mTBI) results in a constellation of symptoms commonly referred to as a concussion. It is unclear why certain individuals experience persistent symptoms. Given the growing evidence linking the microbiome with cognition and inflammation, we examined whether longitudinal microbiome patterns were associated with concussion symptoms.

Tailored Anti-miR Decorated Covalent Organic Framework Enables Electrochemical Detection of Salivary miRNAs for Mild Traumatic Brain Injury.

MicroRNAs (miRNAs) play pivotal role as biomarkers for various diseases, with salivary miRNAs offering a non-invasive diagnostic tool. For mild traumatic brain injury (mTBI), salivary miRNAs like miR-let7a, miR-21, and miR-30e show promise for early detection of subtle injuries lacking reliable indicators. To advance the detection of mTBI-related salivary miRNAs, this study integrates anti-miRNA and miRNA hybridization-based sensing with the development of a nanoscale covalent-organic framework (COF) platform.

Preliminary Evidence for Neuronal Dysfunction Following Adverse Childhood Experiences: An Investigation of Salivary MicroRNA Within a High-Risk Youth Sample.

: Adverse childhood experiences (ACEs) are potent drivers of psychopathology and neurological disorders, especially within minoritized populations. Nonetheless, we lack a coherent understanding of the neuronal mechanisms through which ACEs impact gene expression and, thereby, the development of psychopathology. : This observational pilot study used a novel marker of neuronal functioning (brain-derived micro ribonucleic acids, or miRNAs) collected via saliva to explore the connection between ACEs and neuronal gene expression in 45 adolescents with a collectively high ACE exposure (26 males and 19 females of diverse races/ethnicities, with six cumulative ACEs on average).

A Pilot Study of Saliva MicroRNA Signatures in Children with Moderate-to-Severe Traumatic Brain Injury.

: Traumatic brain injury (TBI) is a leading cause of death and disability in children. Currently, no biological test can predict outcomes in pediatric TBI, complicating medical management. This study sought to identify brain-related micro-ribosomal nucleic acids (miRNAs) in saliva associated with moderate-to-severe TBI in children, offering a potential non-invasive, prognostic tool.

Associations of Maternal Breastmilk microRNAs and Infant Obesity Status at 1 Year.

Infant consumption of human milk (HM) is associated with a reduced risk of overweight and obesity, but the reasons for this relationship are not completely understood. There is emerging evidence that micro RNAs (miRNAs) regulate infant development and metabolism, but the associations between HM miRNAs and infant growth remain poorly understood. We examined the relationship between HM miRNA consumption and infant obesity in 163 mother-infant dyads to determine (1) if miRNA profiles differentiate infants with obesity, and (2) if individual miRNAs accurately predicted infant obesity status at one year of age.

Milk levels of transforming growth factor beta 1 identify mothers with low milk supply.

Human milk is optimal for infant nutrition. However, many mothers cease breastfeeding because of low milk supply (LMS). It is difficult to identify mothers at risk for LMS because its biologic underpinnings are not fully understood.

Infant Saliva Microbiome Activity Modulates Nutritional Impacts on Neurodevelopment.

Neurodevelopment is influenced by complex interactions between environmental factors, including social determinants of health (SDOH), nutrition, and even the microbiome. This longitudinal cohort study of 142 infants tested the hypothesis that microbial activity modulates the effects of nutrition on neurodevelopment. Salivary microbiome activity was measured at 6 months using RNA sequencing.

Saliva microRNA Profile in Children with and without Severe SARS-CoV-2 Infection.

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) may impair immune modulating host microRNAs, causing severe disease. Our objectives were to determine the salivary miRNA profile in children with SARS-CoV-2 infection at presentation and compare the expression in those with and without severe outcomes. Children <18 years with SARS-CoV-2 infection evaluated at two hospitals between March 2021 and February 2022 were prospectively enrolled.
