Accepting multiple conditions in psychiatry: From comorbidity to multimorbidity.

The concept of multimorbidity in psychiatry refers to the coexistence of multiple health conditions without conceptualizing a central disorder referring to a patient-centered approach that views every diagnosis equally. It emphasizes a shift from focusing on an index disorder to considering interrelated symptoms crucial in psychiatry due to frequent multimorbidity patterns. In clinical practice, multimorbidity guides patient-centered care helping to address the holistic needs of patients and challenging the organization of mental health care.

Validation of the French version of the Munich ChronoType questionnaire and associations between chronotype and physiological parameters.

Assessing chronotype is essential in clinical and research environments, but the Munich ChronoType Questionnaire (MCTQ), a widely utilised tool, is not available in French. Therefore, we carried out an observational monocentric study to validate the French MCTQ against the sleep diary for sleep schedules, the Morningness-Eveningness Questionnaire (MEQ) for chronotype, and polysomnography measures. We utilised the mid-sleep point on free days (MSF), adjusted for sleep debt (MSFsc), to gauge morningness/eveningness.

Unraveling the Life History of Past Populations through Hypercementosis: Insights into Cementum Apposition Patterns and Possible Etiologies Using Micro-CT and Confocal Microscopy.

The "teeth-as-tools" hypothesis posits that Neanderthals used their anterior teeth as a tool or a third hand for non-dietary purposes. These non- or para-masticatory activities (e.g.

Sleep timing, workplace well-being and mental health in healthcare workers.

Introduction: Healthcare workers face an elevated risk of burnout, sleep disorders, and mental health issues, potentially stemming from the misalignment of their circadian rhythm due to nonstandard work schedules. This cross-sectional survey aims to examine the connections between sleep timing, workplace well-being (including burnout and absenteeism), and mental health outcomes (specifically depression and poor sleep) in healthcare workers. Additionally, the survey takes into account individual and professional factors, as well as the interaction with work schedules.

Dental sleep medicine education among undergraduate dental students in France.

Introduction: Dental sleep medicine (DSM) is an emerging discipline that studies the oral and maxillofacial causes and consequences of sleep-related problems. DSM is of upmost importance given the major medical challenge it represents. Therefore, to verify whether the future generation of dentists would be ready to face this challenge, the main objective of this study was to assess the degree of involvement of the French dental schools in teaching DSM at the undergraduate level.

From improved sleep regularity to reduced sleep complaints and mental health conditions: a population-based interventional study using a smartphone-based virtual agent.

Study Objectives: To explore the effect of sleep regularity on sleep complaints and mental health conditions (i.e. insomnia, fatigue, anxiety, and depressive symptoms) in a population-based interventional study using a smartphone-based virtual agent.

A Brief History of Tooth Wear.

Historical publications that have significantly improved the understanding of tooth wear mechanisms are reviewed with a focus on descriptions of the lesions, the evolution of their classification systems, and considerations addressing the main risk factors. Surprisingly, most important advances are often the oldest. Likewise, they are currently only marginally known, which requires a major dissemination effort.

An Ultra-Short Measure of Excessive Daytime Sleepiness Is Related to Circadian Biological Rhythms: The French Psychometric Validation of the Barcelona Sleepiness Index.

The Barcelona Sleepiness Index (BSI) is an ultra-short instrument with several advantages for assessing excessive daytime sleepiness (EDS). The present study was performed to analyze the validity of the French version of the BSI in screening for EDS. We conducted a cross-sectional study on a population of students using an online questionnaire.

Factors associated with dental erosions in gastroesophageal reflux disease: a cross-sectional study in patients with heartburn.

Background And Aim: Dental erosion (DE) represents a frequent condition in adults and the elderly. The gastroesophageal reflux disease (GERD) is considered an important endogenous factor causing dental erosions. The objective of this study was to assess the prevalence of DE in GERD patients and to establish the correlation between pathogenic intrinsic and extrinsic factors of DE and their relation to GERD.

Development of a standardized evaluation of endobuccal adverse events induced by repeated tongue protrusion with both a dedicated questionnaire and an endobuccal examination.

Introduction: A new approach to treat obstructive sleep apnea (OSA) is upper airway stimulation therapy (UAS). Electrical pulses applied to the hypoglossal nerve induce tongue protrusion, increase airway patency and decrease the frequency of apneic and hypopneic events. Thus, the main objective of this study was to design a standardized evaluation of endobuccal adverse events induced by repeated tongue protrusion with both a dedicated questionnaire and an endobuccal examination.

Cementochronology, to cut or not to cut?

One of the continuing problems in paleopathology and paleoepidemiology is an inability to accurately age adult skeletons. Accurate age estimations are critical to the proper evaluation of population health and are necessary in circumventing certain aspects of the osteological paradox. Cementochronology is most likely the only age indicator in anthropology that directly considers a continuously growing tissue and does not require either complex statistical manipulations or the use of a reference population.

Mineral density of hypomineralised and sound enamel.

Molar Incisor Hypomineralisation (MIH) is a structural anomaly that affects the quality of tooth enamel and has important consequences for oral health. The developmentally hypomineralised enamel has normal thickness and can range in colour from white to yellow or brown. The purpose of the present study is to compare the mineral density of hypomineralised and normal enamel.

Understanding bruxism in children and adolescents.

Screening for the various forms of bruxism in children and adolescents requires a sound knowledge of the physiopathology of this parafunction in addition to the etiologic and associated factors and comorbidities. The international literature contains various suggestions for suitable treatment. The optimal therapeutic approach often involves multidisciplinary management of these young patients.

Determination and validation of criteria to define hypercementosis in two medieval samples from France (Sains-en-Gohelle, AD 7th-17th century; Jau-Dignac-et-Loirac, AD 7th-8th century).

Objective: The main aim of this article was to develop different visual criteria allowing for an objective definition of hypercementosis (cementum hyperplasia). This preliminary study must notably show how to better understand at a later stage the significance of its frequency as well as its aetiologies, especially in past populations.

Materials And Methods: we set up a study protocol (macroscopic and photographic observations) on material consisting of 2 medieval samples from France (1) Sains-en-Gohelle sample-SG (AD 7th-17th century; 407 individuals; 5756 teeth observed, 319 with hypercementosis) which was used to develop the different criteria for defining hypercementosis (2) Jau-Dignac-et-Loirac sample-JDL (AD 7th-8th century; 55 individuals; 709 teeth observed, 24 with hypercementosis) which was used to test the reproducibility of the criteria.

Human tooth wear in the past and the present: tribological mechanisms, scoring systems, dental and skeletal compensations.

This review of human tooth wear describes the fundamental mechanisms underlying this process. Using the tribological approach they can be systematised and this in turn aids our understanding of them. In past populations wear was ubiquitous, intense, abrasive and physiological as it was related to their food and their technologies.
