Delirium is a critical issue in the intensive care unit (ICU), and the correct diagnosis and treatment of this disorder by the ICU team are doubtful on many occasions due to a lack of information. This research is intended to test the awareness and control of ICU delirium by the ICU nurses. A nonexperimental, quantitative, descriptive, cross-sectional study was conducted using a previously adopted and translated to Arabic and validated questionnaire. The sample include nurses who work in ICUs of 10 Palestinian hospitals (private and public) located in the West Bank and Jerusalem participated in this study; each gave consent to be part of this study. Approval was received from the Palestinian Ministry of Health and the Ethical Committee at Birzeit University. Version 19 of the Social Sciences Statistical Package (SPSS) software was used to analyze the data. The results showed that ICU nurses hold moderate to low levels of knowledge and lack of adequate clinical experience to handle delirium. Delirium is a common complication in the ICU that increases morbidity and mortality and increases the length of ICU stay, therefore the cost of health care rise and the quality of life is decreased. In clinical practice, there are no assessment guidelines and protocols for patients with delirium.

PURPOSE OF REVIEW: We review the ways in which stem cells are used in psychiatric disease research, including the related advances in gene-editing and directed cell differentiation. RECENT FINDINGS: The recent development of induced pluripotent stem cell (iPSC) technologies has created new possibilities for the study psychiatric disease. iPSCs can be derived from patients or controls and differentiated to an array of neuronal and non-neuronal cell types. Their genomes can be edited as desired, and they can be assessed for a variety of phenotypes. This makes them especially interesting for studying genetic variation, which is particularly useful today now that our knowledge on the genetics of psychiatric disease is quickly expanding. SUMMARY: The recent advances in cell engineering have led to powerful new methods for studying psychiatric illness including schizophrenia, bipolar disorder, and autism. There is a wide array of possible applications as illustrated by the many examples from the literature, most of which are cited here.

Schizophrenia is a devastating mental illness with a strong genetic component that is the subject of extensive research. Despite the high heritability, it is well recognized that non-genetic factors such as certain infections, cannabis use, psychosocial stress, childhood adversity, urban environment, and immigrant status also play a role. Whenever genetic and non-genetic factors co-exist, interaction between the two is likely. This means that certain exposures would only be of consequence given a specific genetic makeup. Here, we provide a brief review of studies reporting evidence of such interactions, exploring genes and variants that moderate the effect of the environment to increase risk of developing psychosis. Discovering these interactions is crucial to our understanding of the pathogenesis of complex disorders. It can help in identifying individuals at high risk, in developing individualized treatments and prevention plans, and can influence clinical management.
