Patients with psychiatric disorders exhibit general autonomic dysregulation and elevated cardiovascular risks, which could be indexed by heart rate variability (HRV). However, HRV is susceptible to age and other patient-specific factors. This study aimed to investigate the HRV profile and age-related variations, as well as the potential influence of sex, BMI, and HR on HRV in psychiatric populations.

Article Synopsis
  • - The study investigates how the conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) by TET proteins affects the brain, particularly in postnatal mice lacking Tet genes in excitatory neurons.
  • - Mice without these Tet genes show lowered 5hmC levels, changes in dendritic spine structure, and significant memory deficits, implying a critical role of 5hmC in cognitive function.
  • - Analysis reveals that changes in 5hmC and gene expression are linked to genes tied to synapse development, emphasizing the importance of 5hmC in brain function and health.

Background And Hypothesis: The time taken for an individual who is at the clinical high-risk (CHR) stage to transition to full-blown psychosis may vary from months to years. This temporal aspect, known as the timeframe for conversion to psychosis (TCP), is a crucial but relatively underexplored dimension of psychosis development.

Study Design: The sample consisted of 145 individuals with CHR who completed a 5-year follow-up with a confirmed transition to psychosis within this period.

Psychosis is recognized as one of the largest contributors to nonfatal health loss, and early identification can largely improve routine clinical activity by predicting the psychotic course and guiding treatment. Clinicians have used the clinical high-risk for psychosis (CHR) paradigm to better understand the risk factors that contribute to the onset of psychotic disorders. Clinical factors have been widely applied to calculate the individualized risks for conversion to psychosis 1-2 years later.

Article Synopsis
  • The study aimed to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) on negative symptoms and neurocognitive impairments in first-episode psychosis patients, as current treatments are unsatisfactory.
  • A randomized controlled trial (RCT) was conducted with 85 patients, comparing active rTMS treatment to a sham treatment over four weeks, leading to the identification of two dimensions: neurocognitive functions and negative symptoms.
  • Results showed that while both groups improved, significant reductions in negative symptoms were observed only in the active rTMS group, particularly benefiting patients with severe negative symptoms.

Aim: Although many studies have explored the link between inflammatory markers and psychosis, there is a paucity of research investigating the temporal progression in individuals at clinical high-risk (CHR) who eventually develop full psychosis. To address this gap, we investigated the correlation between serum cytokine levels and Timeframe for Conversion to Psychosis (TCP) in individuals with CHR.

Methods: We enrolled 53 individuals with CHR who completed a 5-year follow-up with a confirmed conversion to psychosis.
