Atypical connectome topography and signal flow in temporal lobe epilepsy.

Temporal lobe epilepsy (TLE) is the most common pharmaco-resistant epilepsy in adults. While primarily associated with mesiotemporal pathology, recent evidence suggests that brain alterations in TLE extend beyond the paralimbic epicenter and impact macroscale function and cognitive functions, particularly memory. Using connectome-wide manifold learning and generative models of effective connectivity, we examined functional topography and directional signal flow patterns between large-scale neural circuits in TLE at rest.

Change in the food environment and measured adiposity in adulthood in the Christchurch Health and development birth cohort, Aotearoa, New Zealand: A birth cohort study.

This study investigated associations between change in the food environment and change in measured body mass index (BMI) and waist circumference (WC) in the Christchurch Health and Development Study (CHDS) birth cohort. Our findings suggest that cohort members who experienced the greatest proportional change towards better access to fast food outlets had the slightly larger increases in BMI and WC. Contrastingly, cohort members who experienced the greatest proportional change towards shorter distance and better access to supermarkets had slightly smaller increases in BMI and WC.

Atypical connectome topography and signal flow in temporal lobe epilepsy.

Temporal lobe epilepsy (TLE) is one of the most common pharmaco-resistant epilepsies in adults. While hippocampal pathology is the hallmark of this condition, emerging evidence indicates that brain alterations extend beyond the mesiotemporal epicenter and affect macroscale brain function and cognition. We studied macroscale functional reorganization in TLE, explored structural substrates, and examined cognitive associations.

DNA methylation patterns at birth predict health outcomes in young adults born very low birthweight.

Background: Individuals born very low birthweight (VLBW) are at increased risk of impaired cardiovascular and respiratory function in adulthood. To identify markers to predict future risk for VLBW individuals, we analyzed DNA methylation at birth and at 28 years in the New Zealand (NZ) VLBW cohort (all infants born < 1500 g in NZ in 1986) compared with age-matched, normal birthweight controls. Associations between neonatal methylation and cardiac structure and function (echocardiography), vascular function and respiratory outcomes at age 28 years were documented.

Behavioral and emotional characteristics of Canadian children with obesity and moderate-severe sleep-disordered breathing treated with positive airway pressure: longitudinal changes and associations with adherence.

Study Objectives: Behavioral characteristics and outcomes of positive airway pressure (PAP) therapy in children with obesity and moderate-severe sleep-disordered breathing (SDB) have not been reported. Our aims were to 1) determine baseline behavioral/emotional symptoms of this population and characterize changes over time with PAP, and 2) examine associations between baseline behavioral/emotional symptoms and PAP adherence.

Methods: This multicenter prospective cohort study of children with obesity prescribed PAP for moderate-severe SDB assessed PAP adherence (≥ 4 h/night, >50% of nights, usage diaries, downloads) and compared behavioral/emotional characteristics with parent- and child-reported Conners Rating Scale (Conners) and the Child Behavior Checklist (CBCL) at baseline and 1 year after PAP prescription between adherent and nonadherent participants; scores at baseline were compared retrospectively between adherence groups.
