Cardiovascular phase, especially diastole, influences attention and the event-related potential (ERP) of the right hemisphere of the brain. Depression and schizophrenia are characterized by attentional deficits, unique lateralization of brain function, and deviant phase relationships of biological oscillators. In the present study, the ERP was recorded during stimulation triggered by diastole and systole in control (n = 16), depressed (n = 16), and schizophrenic (n = 9) subjects. Fifty tones were presented and subjects were instructed to count them silently. Previous findings were supported of delayed latencies and increased amplitude in depressed patients and decreased amplitudes and delayed latencies in schizophrenics. An exaggerated effect of diastole on the ERP in the right hemisphere was observed in depressed patients, however, no cardiovascular effect on the ERP was apparent in schizophrenic patients. Results suggested that heart/brain networks are tightly coupled in normal controls, perhaps "overdriven" in depressed patients, and uncoupled in schizophrenics.

Background: To investigate the effect of Midnight-noon Ebb-flow combined with five-element music therapy in the continuous nursing of patients with chronic wounds.
Methods: From March 2022 to November 2023, we recruited 50 eligible chronic wound patients and randomly divided them into two groups according to a random number table: the experimental group (n = 25) and the control group (n = 25). The control group was treated with conventional nursing measures.
Stigma, Depression, and Attitudes Towards Seeking Psychological Help Among Nurses: The Role of Personal Stigma as an Inconsistent Mediator.
J Eval Clin Pract
February 2025
Department of Biostatistics and Medical Informatics, İnönü University Faculty of Medicine, Malatya, Turkey.
Rationale: Identifying whether perceived stigma or personal stigma more significantly affects nurses' attitudes towards seeking psychological help is essential for effectively addressing current challenges and facilitating early intervention for the well-being of nurses and their patients.
Aims And Objectives: The aim of this study was to explore the mediating roles of personal stigma and depression in the relationship between perceived stigma among nurses and their attitudes towards seeking psychological help.
Methods: The sample of this descriptive cross-sectional study consisted of 302 nurses working in a university hospital in southern Turkey, selected using the purposive sampling method, between April 1 and May 1, 2021.
Effect of psilocybin versus escitalopram on depression symptom severity in patients with moderate-to-severe major depressive disorder: observational 6-month follow-up of a phase 2, double-blind, randomised, controlled trial.

Centre for Psychedelic Research, Division of Psychiatry, Department Brain Sciences, Imperial College London, United Kingdom.
Background: Psilocybin therapy (PT) produces rapid and persistent antidepressant effects in major depressive disorder (MDD). However, the long-term effects of PT have never been compared with gold-standard treatments for MDD such as pharmacotherapy or psychotherapy alone or in combination.
Methods: This is a 6-month follow-up study of a phase 2, double-blind, randomised, controlled trial involving patients with moderate-to-severe MDD.
Advancement in utilization of magnetic resonance imaging and biomarkers in the understanding of schizophrenia.

Historically, psychiatric diagnoses have been made based on patient's reported symptoms applying the criteria from diagnostic and statistical manual of mental disorders. The utilization of neuroimaging or biomarkers to make the diagnosis and manage psychiatric disorders remains a distant goal. There have been several studies that examine brain imaging in psychiatric disorders, but more work is needed to elucidate the complexities of the human brain.
