METHOD PubMed, Embase, and PsycINFO were searched, and studies were selected that 1) identified patients with unipolar major depression, 2) made diagnoses of psychosis based on the presence of delusions or hallucinations, 3) characterized… 
MIIKA NIETOLA: The Risk Factors, Clinical Characteristics and Outcomes of Psychotic Depression
Major depression with psychotic features (psychotic depression, PD) is a severe mental disorder characterized by depression and psychotic symptoms. Despite grave symptoms and high mortality, PD has
Prevalence and clinical profiles of comorbid anxiety in first episode and drug naïve patients with major depressive disorder.
TLDR
The study showed that the prevalence of comorbid anxiety in FEDN patients with MDD is very high and it was found that two clinical variables, suicide attempt and psychosis, are risk factors for comor bid anxiety inFEDn patients withMDD.
Sex differences in psychotic and non-psychotic major depressive disorder in a Chinese Han population.
TLDR
Analysis of variance showed that female patients were older compared with male patients in NPD group, but there were no significant differences in demographic and clinical variables between female and male PD patients, and no sex difference has been observed in the either PD or NPD patients.

Changes in glial gene expression in the prefrontal cortex in relation to major depressive disorder, suicide and psychotic features.
