Article Synopsis
  • - The study investigates attention problems in children born preterm (<30 weeks gestation) from ages 2 to 5, analyzing factors that influence these attention trajectories and their relationship to ADHD diagnoses.
  • - Using data from 608 infants in a large prospective study, researchers found that while most children displayed low initial attention problems, there were notable individual differences in symptom progression over time.
  • - The findings indicate that children with higher initial attention issues and faster increases in symptoms are at a greater risk for an ADHD diagnosis, highlighting the need for tailored interventions based on individual characteristics.

Manipulation of the superficial musculoaponeurotic system (SMAS) has become a mainstay of face lifting procedures. Traditionally, the various surgical approaches to the SMAS have been classified as either "low" or "high" SMAS techniques, the former of which, while expeditious, have been criticized for suboptimal upper midface rejuvenation. High SMAS techniques, by contrast, are lauded for their ability to improve upper midface contours, but may carry increased surgical risk, particularly in the hands of less experienced aesthetic surgeons.

Article Synopsis
  • The study evaluated the Modified Checklist for Autism in Toddlers (M-CHAT) to determine its accuracy as a screening tool for autism in a large sample of nearly 3,400 children from the ECHO program, particularly focusing on both term and preterm children.
  • Results indicated that while the M-CHAT showed high specificity (88-99%), its sensitivity was relatively low (36-60%), suggesting it is better at identifying low-risk children rather than accurately diagnosing those at higher risk for autism.
  • Overall, the findings support the use of M-CHAT as a valuable tool for identifying developmental delays and behavioral concerns in children, even though it has limitations in detecting all cases of autism risk effectively.

An increasing number of researchers are looking to understand the factors affecting microbial dispersion but are often limited by the costs of commercially available air samplers. Some have reduced these costs by designing self-made versions; however, there are no published sampler designs, and there is limited information provided on the actual construction process. Lack of appropriate reference material limits the use of these self-made samplers by many researchers.

Prior research has identified epigenetic predictors of attention problems in school-aged children but has not yet investigated these in young children, or children at elevated risk of attention problems due to preterm birth. The current study evaluated epigenome-wide associations between neonatal DNA methylation and attention problems at age 2 years in children born very preterm. Participants included 441 children from the Neonatal Neurobehavior and Outcomes in Very Preterm Infants (NOVI) Study, a multi-site study of infants born < 30 weeks gestational age.

Although improved knowledge on the movement of airborne plant pathogens is likely to benefit plant health management, generating this knowledge is often far more complicated than anticipated. This complexity is driven by the dynamic nature of environmental variables, diversity among pathosystems that are targeted, and the unique needs of each research group. When using a rotating-arm impaction sampler, particle collection is dependent on the pathogen, environment, research objectives, and limitations (monetary, environmental, or labor).

Children born less than 30 weeks gestational age (GA) are at high risk for neurodevelopmental delay compared to term peers. Prenatal risk factors and neonatal epigenetics could help identify preterm children at highest risk for poor cognitive outcomes. We aimed to understand the associations among cumulative prenatal risk, neonatal DNA methylation, and child cognitive ability at age 3 years, including whether DNA methylation mediates the association between prenatal risk and cognitive ability.

Background/aim: Progesterone receptor antagonists have been found to provide significant extension of life and considerable palliative benefits in a large variety of very advanced cancers. Most of these treated cancers lack the classical nuclear progesterone receptor (nPR). The hypothesized targets are membrane (m) PRs to inhibit progesterone induced blocking factor (PIBF).

Importance: Use of the Modified Checklist for Autism in Toddlers, Revised With Follow-Up, a 2-stage parent-report autism risk screening tool, has been questioned due to reports of poor sensitivity and specificity. How this measure captures developmental delays for very preterm infants may provide support for continued use in pediatric care settings.

Objective: To determine whether autism risk screening with the 2-stage parent-report autism risk screening tool at age 2 years is associated with behavioral and developmental outcomes at age 3 in very preterm infants.

Epigenetic age acceleration is a risk factor for chronic diseases of ageing and may reflect aspects of biological ageing. However, few studies have examined epigenetic ageing during the early neonatal period in preterm infants, who are at heightened risk of developmental problems. We examined relationships between neonatal age acceleration, neonatal morbidities, and neurobehavioral domains among very preterm (<30 weeks gestation) infants to characterize whether infants with early morbidities or different neurobehavioral characteristics had accelerated or decelerated epigenetic ageing.

Background: Very preterm infants are at high risk for neurodevelopmental impairments. We used a child-centered approach (latent profile analysis [LPA]) to describe 2-year neurobehavioral profiles for very preterm infants based on cognitive, motor, and behavioral outcomes. We hypothesized that distinct outcome profiles would differ in the severity and co-occurrence of neurodevelopmental and behavioral impairment.
