AI Article Synopsis
- Delirium is a serious complication linked to increased health risks and costs, prompting a focus on prevention, particularly through the study of sleep disturbances.
- This literature review examines the relationship between sleep disturbances and delirium, highlighting that while associations exist, no definitive causality has been established; thus, more robust evidence is necessary.
- The study suggests that both nonpharmacological and pharmacological approaches could help prevent delirium, recommending screening for sleep issues in at-risk patients, but calls for further research to solidify these findings.
Article Abstract
Background: Delirium is considered a severe complication. It increases morbidity and mortality and represents a major financial burden for healthcare systems. Thus, prevention becomes a focal point of research. Sleep disturbances have been linked to the occurrence of delirium. Consequently, several interventions that target a possible connection have been studied in recent years.
Objective: This narrative literature review explores the published data for an association between delirium and different types of sleep disturbances, the pathophysiological interactions and prevention methods.
Material And Methods: A literature search was carried out utilizing PubMed, the Cochrane Library, Livivo and Google Scholar.
Results: Although an association between several types of sleep disturbances and delirium has been shown, no causality has been proven so far. Nevertheless, several pharmacological and nonpharmacological interventions for delirium prevention have been attempted; however, the level of evidence is insufficient at this point.
Conclusion: Further research is required to prove causality between sleep disturbances and delirium. Nonpharmacological interventions should be used in construction and maintenance of intensive care units and hospitals. Pharmacological interventions could be effective for prevention but further research is needed. Screening patients at risk of delirium for sleep disturbances and antihistaminergic/anticholinergic medication seems beneficial.

Background: Non-motor symptoms, including depression, anxiety, sleep disturbances, pain and cognitive dysfunction, are a much more important predictor of quality of life than the severity of dystonia.
Objectives: To assess the effect of Botulinum toxin on non-motor symptoms and quality of life in patients with adult-onset idiopathic focal dystonia.
Methods: Patients aged > 18 years diagnosed with idiopathic focal dystonia were recruited in this longitudinal cohort study.
European central hypoventilation syndrome consortium description of congenital central hypoventilation syndrome neonatal onset.

Unlabelled: It is known that in most cases of congenital central hypoventilation syndrome (CCHS), apnoeas and hypoventilation occur at birth. Nevertheless, a detailed description of initial symptoms, including pregnancy events and diagnostic tests performed, is warranted in infants with neonatal onset of CCHS, that is, in the first month of life. The European Central Hypoventilation Syndrome Consortium created an online patient registry from which 97 infants (44 females) with CCHS of neonatal onset and PHOX2B mutation from 10 countries were selected.

Comparison of NoSAS score with STOP-Bang and Berlin scores in predicting difficult airway.
BMC Anesthesiol
January 2025
Department of Anesthesiology and Reanimation, Faculty of Medicine, Suleyman Demirel University, Operating Room, Floor:1, Cunur, Isparta, 32260, Turkey.
Background: This study aimed to compare the effectiveness of the NoSAS, STOP-Bang, and Berlin scoring systems, which are utilized to predict obstructive sleep apnea syndrome (OSAS), in forecasting difficult airway management. Additionally, the study sought to determine which of these scoring systems is the most practical and effective for this purpose.
Methods: Following the ethics committee approval, preoperative NoSAS, STOP-Bang, and Berlin scores were calculated for 420 patients aged 18 years and older who were scheduled for tracheal intubation.

Introduction: Sleep plays a crucial role in health, well-being, and academic performance. Despite the recognized importance of good sleep for students, there is a need for a deeper understanding of the sleep problems faced by university students to inform effective campus support services and interventions. This study aimed to evaluate sleep quality among university students by assessing differences in key sleep parameters between sex and age groups.
