Implications of attention‐deficit/hyperactivity disorder diagnostic timing on mental health service utilisation in young adult females: A population‐based record linkage cohort study

JCPP Advances, EarlyView.
Abstract Background Sex differences in the frequency and timing of attention‐deficit/hyperactivity disorder (ADHD) diagnosis exist. While there are multiple known individual and wider consequences for young females with delayed or undiagnosed ADHD, little is known about mental health service utilisation (HSU) impacts.

Seasonal Characteristics of Mesoscale Convective Systems Over the Philippines

International Journal of Climatology, EarlyView.
This study examines how mesoscale convective systems (MCSs) over the Philippines are most frequent during boreal summer, while those in winter are longer‐lived and more intense due to cold surges and enhanced easterly moisture transport. Intraseasonal oscillations, such as the Madden‐Julian Oscillation (MJO) and the Boreal Summer Intraseasonal ...
