We designed and validated a system for determining the state of sleep or wakefulness in both term and preterm infants. The system is based on independent assessments of behavioral and electroencephalographic (EEG) patterns. Overall agreement between observers in coding individual behavioral patterns was 77.6%. Agreement between observers in coding EEG patterns was 87.4%. Designation of an infant's state is made by combining concurrent behavioral and EEG scores into a single two-number code. The distribution of sleep state for eight infants greater than 36 wk postconceptional age (PCA) was the following: quiet sleep (QS), 30.4%; active sleep (AS), 50.0%; indeterminate sleep (IS), 11.4%, and wakefulness (W), 7.5%. The distribution of sleep state for 15 infants less than 36 wk PCA was as follows: QS, 18.9%; AS, 52.9%; IS, 16.4%; and W, 10.5%. Our experience with the system suggests that it is useful for relating sleep state to physiologic variables during neonatal experimental studies.

The dorsolateral prefrontal cortex (dlPFC) is increasingly targeted by various noninvasive transcranial magnetic stimulation or transcranial current stimulation protocols in a range of neuropsychiatric and other brain disorders. The rationale for this therapeutic modulation remains elusive. A model is proposed, and up-to-date evidence is discussed, suggesting that the dlPFC is a high-level cortical centre where uncertainty management, movement facilitation, and cardiovascular control processes are intertwined and integrated to deliver optimal behavioural responses in particular environmental or emotional contexts.

Diabetes mellitus (DM) is a debilitating disorder that impacts all systems of the body and has been increasing in prevalence throughout the globe. DM represents a significant clinical challenge to care for individuals and prevent the onset of chronic disability and ultimately death. Underlying cellular mechanisms for the onset and development of DM are multi-factorial in origin and involve pathways associated with the production of reactive oxygen species and the generation of oxidative stress as well as the dysfunction of mitochondrial cellular organelles, programmed cell death, and circadian rhythm impairments.

Background: Malaria continues to be an important threat to public health and infects millions of children under 5 years of age each year. Although Ethiopia has set targets for at-risk group interventions to eradicate and manage malaria, the illness is still a serious public health problem in areas where it is endemic, especially in the unique lowlands in the Borena zone.
Objective: This study aimed to determine the prevalence of malaria and associated factors among children in Borena's pastoral communities, Oromia Regional State, southern Ethiopia, in 2022.
Sleep problems and parental stress among caregivers of children and adolescents enrolled in a digital mental health intervention.

Introduction: Caregivers of children with mental health problems such as anxiety, depression, and attention-deficit/hyperactivity disorder often experience heightened sleep problems, largely due to their children's disrupted sleep, and increased parental stress. Evidence suggests that mental and behavioral health care for children and adolescents has the potential to positively affect their caregivers; however, this has not been investigated in the context of pediatric digital mental health interventions (DMHIs). Therefore, the current study used caregivers' self-report measures to determine whether caregivers whose children are involved in a DMHI exhibit improvements in sleep problems and parental stress after initiation of their children's care.
