Anthropometric differences between twins at birth and their association with later cognitive performance

Journal of Child Psychology and Psychiatry, EarlyView.
Background Past studies indicate significant associations between birth anthropometrics, such as relative birthweight or head circumference, and later cognitive performance. Using twin data, we investigated whether these associations are confounded by genetic and environmental factors.

Chronic insomnia, REM sleep instability and emotional dysregulation: A pathway to anxiety and depression?

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The world‐wide prevalence of insomnia disorder reaches up to 10% of the adult population. Women are more often afflicted than men, and insomnia disorder is a risk factor for somatic and mental illness, especially depression and anxiety disorders.

Feasibility and usability of three consecutive nights with self‐applied, home polysomnography

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary In‐laboratory polysomnography, the gold‐standard for diagnosing sleep disorders, is resource‐demanding and not conducive to multiple night evaluations. Ambulatory polysomnography, especially when self‐applied, could be a viable alternative. This study aimed to assess the feasibility and reliability of self‐applied polysomnography over three ...

The N-soliton solutions of the n-component generalized Sasa-Satsuma system: Riemann-Hilbert method

Nuclear Physics B
Using the Riemann-Hilbert method, the paper systematically investigates the n-component generalized Sasa-Satsuma system. By utilizing the Tu scheme, we systematically construct the n-component generalized Sasa-Satsuma integrable hierarchy, and obtain the

The Interplay Between Emotion Dysregulation and Repetitive Thoughts in Insomnia Disorder: The Impact of Worry, Rumination and REM Sleep Instability

Journal of Sleep Research, EarlyView.
ABSTRACT While previous research has identified emotional dysregulation and repetitive thinking as contributors to insomnia, the interplay between these factors remains unclear. Building upon data previously collected in our laboratory, this exploratory study extends prior findings by examining the mediating role of rumination, worry and rapid eye ...

One‐Session Cognitive Behavioural Therapy for Insomnia in Integrated Primary Care: A Preliminary Study

Journal of Sleep Research, EarlyView.
ABSTRACT Chronic insomnia is commonly reported in primary care settings. One‐session cognitive behavioural therapy for insomnia (CBT‐I) is a brief intervention designed to fit the fast‐paced nature of primary care but has not been studied in this context.

A nonlocal problem for fourth order hyperbolic equations with multiple characteristic

Electronic Journal of Differential Equations, 2002
In this paper, we study fourth order differential equations with multiple characteristics and dominated low terms. We prove the existence and uniqueness of a Riemann function for this equation, and then provide an integral representation of the general ...

Prescription of Psychotropic Drugs for Chronic Insomnia in Primary Care

Journal of Sleep Research, EarlyView.
ABSTRACT Insomnia is the most prevalent sleep disorder in adults, representing a major public health problem. Healthcare management in a specific area first requires analysing its current practices and issues. We conducted a retrospective observational study of over 100,000 patients from two large primary care databases in the public healthcare ...

Risks Associated With Benzodiazepine Long‐Term Use in Chronic Insomnia: A Systematic Review and (Network) Meta‐Analysis

Journal of Sleep Research, EarlyView.
ABSTRACT This systematic literature review evaluated the risks of using benzodiazepine medications for more than 3 months in adults with chronic insomnia. Chronic insomnia is defined as ongoing dissatisfaction with sleep quantity or quality, causing significant distress and impaired functioning during the day.
