Analyzing scored sleep is a fundamental prerequisite to understanding how sleep changes between health and disease. Classically, this is accomplished by manually calculating various measures (e.g., percent of non-rapid eye movement sleep) from a collection of scored sleep files. This process can be tedious and error prone especially when studies include a large number of animals or involve long recording sessions. To address this issue, we present SleepInvestigatoR, a versatile tool that can quickly organize and analyze multiple scored sleep files into a single output. The function is written in the open-source statistical language R and has a total of 25 parameters that can be set to match a wide variety of experimenter needs. SleepInvestigatoR delivers a total of 22 unique measures of sleep, including all measures commonly reported in the rodent literature. A simple plotting function is also provided to quickly graph and visualize the scored data. All code is designed to be implemented with little formal coding knowledge and step-by-step instructions are provided on the corresponding GitHub page. Overall, SleepInvestigatoR provides the sleep researcher a critical tool to increase efficiency, interpretation, and reproducibility in analyzing scored rodent sleep.

Prevalence of Obstructive Sleep Apnea in Vietnamese Children with Attention Deficit Hyperactivity Disorder (ADHD).
Pulm Ther
January 2025
Bio-Medical Research Center, Lam Dong Medical College, Dalat, Vietnam.
Introduction: Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder among children with attention deficit hyperactivity disorder (ADHD). This study aims to determine the prevalence of OSA in children with ADHD, compare the differences in clinical characteristics between children with ADHD-OSA and those without OSA (ADHD-nonOSA), and to identify the correlation between OSA and ADHD in children.
Methods: This cross-sectional descriptive study was conducted on 524 children with ADHD, aged 6-12 years, at the Vietnam National Children's Hospital from October 2022 to September 2023.
Background: Polysomnography (PSG) is resource-intensive but remains the gold standard for diagnosing Obstructive Sleep Apnea (OSA). We aimed to develop a screening tool to better allocate resources by identifying individuals at higher risk for OSA, overcoming limitations of current tools that may under-diagnose based on self-reported symptoms.
Methods: A total of 884 patients (490 diagnosed with OSA) were included, which was divided into the training, validation, and test sets.
Using machine learning models to identify severe subjective cognitive decline and related factors in nurses during the menopause transition: a pilot study.
Menopause
January 2025
From the School of Nursing and Rehabilitation, Shandong University, Jinan, Shandong, China.
Objective: This study aims to develop and validate a machine learning model for identifying individuals within the nursing population experiencing severe subjective cognitive decline (SCD) during the menopause transition, along with their associated factors.
Methods: A secondary analysis was performed using cross-sectional data from 1,264 nurses undergoing the menopause transition. The data set was randomly split into training (75%) and validation sets (25%), with the Bortua algorithm employed for feature selection.
Association of self-monitoring performance of cognitive performance with personal diurnal preference when sleep-deprived.

Research Center for Overwork-Related Disorders, National Institute of Occupational Safety and Health, Kawasaki, Japan.
In modern society, many workers struggle with sleep deprivation due to their work schedules and excessive workloads. Accurate self-awareness and self-monitoring abilities are crucial for workers to adopt risk-coping strategies and protective behaviors when fatigued. The current study examined the relationship between chronotypes and self-monitoring performance during 24 h of sleep deprivation.

Background: Evidence supports the common incidence of sleep disturbance in opioid use disorder (OUD) as a potential marker of disrupted orexin system functioning. This study evaluated the initial safety and tolerability of a challenge dose of lemborexant, a dual orexin antagonist, as an adjunct to buprenorphine/naloxone.
Methods: Patients (18-65 years old) with OUD receiving sublingual buprenorphine/naloxone, with a Pittsburgh Sleep Quality Index total score of 6 or higher, were recruited from outpatient clinics.
