Transcranial magnetic stimulation (TMS) is applied both in research settings and clinically, notably in treating depression through the dorsolateral prefrontal cortex (dlPFC). We have recently shown that transcranial alternating current stimulation of the dlPFC partially entrains muscle sympathetic nerve activity (MSNA) to the stimulus. We, therefore, aimed to further explore the sympathetic properties of the dlPFC, hypothesizing that single-pulse TMS could generate de novo MSNA bursts.

Background: Almost 40% of individuals at ultra-high risk (UHR) for psychosis experience persistent attenuated psychotic symptoms (APS) yet it is unclear (1) whether they share overlapping clinical and functional outcomes compared to individuals who transition to psychosis, (2) when symptom and functioning trajectories begin to diverge between UHR individuals with different clinical outcomes, and (3) whether non-remission (persistent APS or transition) can be predicted using baseline and/or longitudinal data.

Study Design: Participants were drawn from 2 randomized clinical trials: Neurapro (n = 220; discovery sample) and STEP (n = 180; external validation sample). First, 12-24 month symptoms and functioning were compared between UHR individuals with persistent APS, sustained remission, or transition to psychosis.

Over the last decade metagenomic sequencing has facilitated an increasing number of virome-scale studies, leading to an exponential expansion in understanding of virus diversity. This is partially driven by the decreasing costs of metagenomic sequencing, improvements in computational tools for revealing novel viruses, and an increased understanding of the key role that viruses play in human and animal health. A central concern associated with this remarkable increase in the number of virome-scale studies is the lack of broadly accepted "gold standards" for reporting the data and results generated.
