Article Abstract
Background: This study focuses on the development of a neural network model to predict perceived sleep quality using data from wearable devices. We collected various physiological metrics from 18 participants over four weeks, including heart rate, physical activity, and both device-measured and self-reported sleep quality.
Objectives: The primary objective was to correlate wearable device data with subjective sleep quality perceptions.
Methods: Our approach used data processing, feature engineering, and optimizing a Multi-Layer Perceptron classifier.
Results: Despite comprehensive data analysis and model experimentation, the predictive accuracy for perceived sleep quality was moderate (59%), highlighting the complexities in accurately quantifying subjective sleep experiences through wearable data. Applying a tolerance of 1 grade (on a scale from 1-5), increased accuracy to 92%.
Discussion: More in-depth analysis is required to fully comprehend how wearables and artificial intelligence might assist in understanding sleep behavior.

Background: Although opioid analgesics may influence sleep in patients with chronic pain, the association between strong opioid use and sleep characteristics remains unclear. This study aimed to explore differences in sleep status among chronic pain patients with varying levels of opioid use.
Methods: A total of 29 patients with chronic non-cancer pain who had been under treatment for more than 6 months were included.

Aim: To systematically review randomized controlled trials evaluating the efficacy of sleep-oriented non-pharmacological interventions for delirium prevention in intensive care units.
Methods: We searched PubMed, Web of Science, Scopus, and the Cochrane Library for randomized controlled trials evaluating the efficacy of sleep-oriented, non-pharmacological interventions for delirium prevention in intensive care units published in English between 2019 and 2024. The methodological quality of the included studies was independently evaluated by two researchers using the Joanna Briggs Institute tool.

Background: Major depressive disorder (MDD), anxiety disorders, and self-harm are substantial contributors to the global disease burden, exacerbated by the COVID-19 pandemic.
Methods: We used Global Burden of Diseases Study (GBD) 2021 to estimate global, regional, and national prevalence, mortality, and disability-adjusted life years (DALYs) for MDD, anxiety disorders, and self-harm from 1990 to 2021. Annual percentage changes were calculated for pre-pandemic (1990-2019) and pandemic (2019-2021) periods.

Department of Public Health and Infectious Diseases, Pulmonology Unit, Policlinico Umberto I, "Sapienza" University of Rome, 00185 Rome, Italy.
Purpose: Asthma and obstructive sleep apnea (OSA) are two respiratory diseases that often may coexist, resulting in Alternative Overlap Syndrome (aOVS), which is still underestimated and underdiagnosed.
Objectives: This state-of-art review aims to describe the current evidence on aOVS, including its pathophysiology, clinical, functional and therapeutic implications. A secondary objective is to assess whether aOVS can be identified as a distinct endophenotype needing personalized diagnostic and therapeutic strategies.
