Background/Objectives: Orthosomnia has become a concern in the field of sleep medicine. The purpose of this cross-sectional study was to estimate the prevalence of orthosomnia in the general population. Methods: We collected data from 523 participants via the Generalized Anxiety Disorder Scale, Anxiety and Preoccupation about Sleep Questionnaire, and Athens Insomnia Scale. Additionally, we gathered information about participants' use of commercial sleep-tracking wearable devices. Results: We developed a four-criteria algorithm to identify cases of orthosomnia: ownership of a wearable sleep-tracking device, AIS score ≥ 6, GAD-7 score ≤ 14, and APSQ score ≥ 40 or APSQ score ≥ 35 or APSQ score ≥ 30, for conservative, moderate, and lenient prevalence estimates, respectively. One hundred seventy-six (35.8%) (95% CI 34.6–40.1%) participants regularly used sleep-tracking devices. The prevalence rates of algorithm-identified orthosomnia in the study sample were: 16 participants (3.0%, 95% CI 1.6–4.5%), 45 participants (8.6%, 95% CI 6.2–11.0%), 73 participants (14.0%, 95% CI 10.9–16.9%) for the for conservative, moderate, and lenient prevalence estimates, respectively. Individuals with orthosomnia were not significantly different in terms of age and sex. The cases consistently had higher AIS scores than non-cases across all APSQ cutoffs, indicating more severe insomnia symptoms, with significant differences observed at each cutoff point. Conclusions: This study offers initial insights into the prevalence of orthosomnia within our sample at a specific time. The findings reveal notable rates of orthosomnia among individuals using sleep-tracking devices; however, we must acknowledge the limitations inherent in a cross-sectional design.

Staging platform (SP) uses a modified Gates Glidden (GG) to help retrieve separated instruments deep in the root canal. However, GG drills may cause damage or severe dentin loss. A 46‑year‑old male patient was referred to the endodontic postgraduate clinics complaining of pain on biting related to the mandibular right second molar (#47). The preoperative periapical radiograph of #47 showed a previously initiated root canal treatment with an approximately 8‑mm separated instrument in the apical third of a curved mesiolingual canal. A nickel–titanium (NiTi) rotary file size 25/0.04 was flattened with a carbide bur. The modified file was then used to create a centered SP. After SP was achieved, an ultrasonic tip was used at lower power for the trephination of dentin. The fragment became loose, and retrieval was achieved. The use of a modified NiTi rotary file presented a safe and alternative option to establish SP for instrument retrieval instead of using GG drills. [ABSTRACT FROM AUTHOR]

Chronotype is an established concept designed to capture the internal clock's phase in real-life conditions. It is vital in many aspects of daily life and can interfere considerably with numerous factors in a given population. Recognizing nonmodifiable and modifiable factors is crucial for identifying covariates of interest when studying the link between chronotype and health status. To date, chronotype and its related factors have not been extensively investigated. The present study aimed to explore the association of chronotypes with meal frequency, physical activity, and demographic factors among the Saudi population. This cross-sectional web-based questionnaire involved 1369 adults (aged 18 years and above) from the general public in Saudi Arabia and was conducted between March and May 2019. Chronotype was assessed using the reduced version of the original Horne and Ostberg morningness-eveningness questionnaire (MEQ). Meal frequencies and demographics data (age, gender, marital status, place of residence, educational level, employment status, income) were obtained. Physical activity level was also obtained using the international physical activity questionnaire. The MEQ scores group individuals into three categories: morning-type, neither-type, and evening-type. The neither-type individuals represented 41.6% (95% confidence interval [CI], 37.5% − 45.6%) of the study population, followed by the morning-type (34.1%; 95% [CI], 29.8% − 38.4%), then the evening-type (24.3%, 95% [CI], 19.6% − 28.9%). Chronotype was significantly associated with age, marital status, employment status and monthly income (All p < 0.05). Significant associations between chronotype with meal frequencies (number of meals per day, breakfast frequency, lunch frequency, and dinner frequency) and physical activity were also observed (All p < 0.05). This study highlights that meal frequencies and physical activity levels are associated with chronotype distribution. Furthermore, demographics, including age, marital status, employment status, and income, were associated with chronotype distribution. [ABSTRACT FROM AUTHOR]

Nomophobia, often known as a 21st-century disorder, is a recent condition that has received considerable attention, with numerous studies conducted to better understand it since it was first introduced in 2008. To better understand the present research status and prospects to assist practitioners, policymakers, and funding agencies in protecting the population from nomophobia-related harm, a bibliometric study of nomophobia-related publications was conducted. We used Scopus and dimensions.ai to perform a search between 2008 and 2022. The HistCite, R software, and VOSviewer were used to analyze the data and extract relevant keywords indexed in medical databases using mesh heading phrases. Between January 2008 and April 2022, 1,781 papers, 30 datasets, two grants, six patents, four clinical trials, and five policy documents were identified. The bulk of the articles included in this review were published after 2017 with the majority written in English. Most of the research focuses on determining the prevalence of nomophobia in various populational groups, such as students, clinical samples, and the general adult population. Several studies examined the possible association between nomophobia symptoms and other psychiatric or physical health issues, such as changes in sleep, learning and attention, academic performance, coping strategies, etc. The current body of research knowledge of nomophobia in the main includes epidemiologic and diagnostic effort that has provided mixed results regarding its assessment and prevalence rates, and appreciable data on its treatment and prevention are lacking.
