Characteristics of Sleep Paralysis and Its Association with Anxiety Symptoms, Perceived Stress, PTSD, and Other Variables Related to Lifestyle in Selected High Stress Exposed Professions.

Sleep paralysis (SP) is a hypnagogic or hypnopompic state associated with the inability to move while conscious. Recurrent isolated sleep paralysis (RISP) is a type of REM parasomnia. Individuals experiencing anxiety disorders, PTSD, exposure to chronic stress, or shift work are at risk of developing this sleep disorder.

Risk factors of sleep paralysis in a population of Polish students.

Background: Sleep paralysis (SP) is a transitional dissociative state associated with the REM sleep phase that affects approximately 28.3% of the student population during their lifetime. The reasons for the high prevalence of SP in the student population are not entirely clear.

Disruptions within gut microbiota composition induced by improper antibiotics therapy as a probable trigger factor for development of depression - Case Reports.

A growing body of evidence confirms that immune activation and low-grade inflammation could be defined as risks factors for the development and progression of mood episodes. A suggested mechanism leading to immune-inflammatory imbalance is the change in gut microbiota composition provoked by intestinal permeability. Three cases of patients with first episode of depression: a 30-year-old man and two 41 and 46-year-old women are presented in the study.

Oxidative Stress Biomarkers as a Predictor of Stage Illness and Clinical Course of Schizophrenia.

Pro/antioxidant imbalance has been reported in schizophrenia (SZ). However, the results of studies are inconsistent and usually do not include other factors that are highly affected by oxidative stress (OS).This cross-sectional study aimed to determine the serum levels of OS markers and their potential connection with schizophrenia.

Pro/Antioxidant State as a Potential Biomarker of Schizophrenia.

To allow better diagnosis and management of psychiatric illnesses, the use of easily accessible biomarkers are proposed. Therefore, recognition of some diseases by a set of related pathogenesis biomarkers is a promising approach. The study aims to assess the usefulness of examining oxidative stress (OS) in schizophrenia as a potential biomarker of illness using the commonly used data mining decision tree method.
