Rythm

BACKGROUND: Machine learning and deep learning techniques are now used extensively for atrial fibrillation (AF) screening, but their use for AF crisis forecasting has yet to be assessed in a clinical context. AIMS: To assess the value of two machine learning algorithms for the short-term prediction of paroxysmal AF episodes. METHODS: We conducted a retrospective study from an outpatient clinic. We developed a deep neural network model that was trained for a supervised binary classification, differentiating between RR interval variations that precede AF onset and RR interval variations far from any AF...

BACKGROUND: The transport sector is a male-dominated, sedentary, accident-prone occupation with limited opportunities for healthy meals and exercise breaks. Since stress is a recognized risk factor in the development of addiction and addiction relapse susceptibility, we explored relationship between stress perception and self-reported lifestyles with Health-related Quality of Life (HRQOL) among long distance Bus Drivers in Lagos State. METHODS: 200 randomly enlisted commercial drivers from bus terminals in Lagos State were interviewed face-to-face using a validated structured questionnaire...

Does the timing of when children, youth and adults participate in physical activity, sedentary behaviour (e.g. screen time) and sleep matter when it comes to their overall health? This special issue of Health Promotion and Chronic Disease Prevention in Canada includes four papers that present evidence and recommendations on the timing of movement behaviours: three separate systematic reviews exploring the associations between health indicators and the timing of physical activity, sedentary behaviour and sleep; and a commentary that discusses the importance of this evidence in terms of practice, policy and research...

Sleep disturbances are extremely common (40-86%) in children and adolescents, especially those with autism spectrum disorders (ASD) and are often among the first symptoms identified by parents at a very early stage of their child's development. These abnormalities are among the main parental concerns when having a child with ASD and have a significant impact on the quality of life of patients, their parents, and more broadly their siblings. Sleep disorders are essentially abnormalities of the sleep-wake rhythm - primarily sleep onset insomnia or nocturnal awakenings (with difficulty falling back to sleep)...

INTRODUCTION: Sleep disorders are prevalent in patients with a neurocognitive disorder, and diagnosis and treatment in these patients remain challenging in clinical practice. METHODS: This narrative review offers a systematic approach to diagnose and treat sleep disorders in neurocognitive disorders. RESULTS: Alzheimer's disease is often associated with circadian rhythm disorders, chronic insomnia, and sleep apnea-hypopnea syndrome. Alpha-synucleinopathies (e...

OBJECTIVE: Sleep health is a major public health concern because of its correlation with physical and mental health, and it may be particularly altered in medical students. This study aims: i) to examine the sleep characteristics of French medical students and their knowledge about basic sleep hygiene rules and; ii) to examine the correlations between sleep quality and academic performances, as well as between sleep quality and sleep knowledge. METHODS: Students from 4th, 5th and 6th years of medicine, of the Faculty of Paris Diderot, voluntarily responded to an online questionnaire including PSQI and multiple-choice quizzes (MCQ) about basic sleep hygiene rules...

INTRODUCTION: Insomnia is a sleep disorder that particularly affects teenagers. Its psychic and physical consequences are major and make it a public health priority. The main purpose of the study was to provide contemporary data on adolescent sleep and to explore the intrications between insomnia and mood disorders while investigating the chronotype responsibility. METHOD: A battery of questionnaires was offered to 1,036 French teenagers, enrolled in secondary school, aged between 12 and 20 years old and living in urban areas for middle school students and in rural areas for high school students...

Quality of life in the workplace is something that nursing students have to think about. During their internships in particular, they have been able to get an idea of what awaits them in the field, and they have no shortage of ideas and proposals for improving their future working conditions, and thus the quality of care provided to patients.

In 1992, the Laboratory of Human Physiology at the University of Parma (Italy) publish a study describing "mirror" neurons in the macaque that activate both when the monkey performs an action and when it observes an experimenter performing the same action. The research team behind this discovery postulates that the mirror neurons system is the neural basis of our ability to understand the actions of others, through the motor mapping of the observed action on the observer's motor repertory (direct-matching hypothesis)...

OBJECTIVES: Time-dependent effects of alpha-lipoic acid/nifedipine/glimepiride combination on diabetic neuropathies were investigated in rats. 7 groups (n=9) of rats were used. MATERIALS AND METHODS: First and second groups were apparently normal and diabetic rats respectively, and were administered 1mL/kg distilled water. The rest of the groups were diabetic and administered 10mg/kg glimepiride at night-time (8:00 pm). Groups 4-7 were administered additional 20mg/kg nifedipine at morning-time (8:00 am), while groups 5-7 were also administered 100mg/kg alpha-lipoic acid (ALA) in the morning, afternoon and night-time respectively (8:00 am, 2:00 pm and 8:00 pm)...

Mouse behavior is a primary outcome in evaluations of therapeutic efficacy. Exhaustive, continuous, multiparametric behavioral phenotyping is a valuable tool for understanding the pathophysiological status of mouse brain diseases. Automated home cage behavior analysis produces highly granulated data both in terms of number of features and sampling frequency. Previously, we demonstrated several ways to reduce feature dimensionality. In this study, we propose novel approaches for analyzing 33-Hz data generated by CleverSys software...

Background: Atrial fibrillation surgical radiofrequency ablation (AFSA) during mitral valve surgery (MVS) has almost completely superseded the Cox-Maze procedure for the treatment of atrial fibrillation. Methods: We retrospectively analyzed 100 patients who underwent MVS + AFSA in our institution from January 2008 to June 2017. We compared the effectiveness of AFSA in patients who underwent LAA exclusion to those who did not. Moreover, we analyzed the role of preoperative AF duration (≤ or >1 year) and medial-lateral left atrial dimensions (ML-LAD) (≤ or >6 cm)...

OBJECTIVE: The circadian rhythm is the most important of the main rhythms that affect our daily lives and has a significant role in the efficiency of a lot of drugs used in anesthesia. The aim of this study is to prove whether circadian rythm has an effect on spinal anesthesia and, if any, its effect on postoperative analgesic request by retrospectively studying the patients operated under spinal anesthesia. METHODS: We conducted the study on patients operated on inguinal hernia and anorectal surgery under spinal anesthesia in general surgery room...

INTRODUCTION: According to many studies, exposure to air pollution increases cardiovascular morbidity and mortality. It has also been shown that the frequency of heart rhythm disorders in Region wallonne is very high. OBJECTIVES: The objective of this study is to test the hypothesis of a link between rhythm disorders measured by cardiac holters and data from devices measuring the concentration of air pollutants present in ambient air. METHODOLOGY: The health data were obtained via the Erasme hospital's cardiology center...

Mycotoxins are secondary metabolites produced by a variety of fungi that contaminate food and feed resources, and are capable of inducing a wide range of toxicity. Here, we studied the developmental and behavioral toxicity in zebrafish (Danio rerio) embryos and larvae exposed to three mycotoxins: beauvericin (BEA), Enniatin A (ENN A), and Ennitain B (ENN B). Zebrafish embryos were collected after fertilization, treated individually from 1 to 6 dpf with BEA at 8, 16, 32 and, 64 μM and for both enniatins at 3...

Time is a key element of nursing. This is true for professional practice as well as for training. During practice placements, students discover the reality of a profession in which different temporalities come together, their own, as well as those of the patients and the institution. First year and third year students share their experience.

Les données recueillies lors de crises et tragédies passées prouvent que les problèmes de sommeil survenant durant ou peu de temps après un événement traumatique sont reliés à une probabilité accrue de développer des symptômes psychiatriques durables. Or la pandémie COVID-19 et ses conséquences à moyen et long-terme combinent plusieurs facteurs de risque pour le sommeil, tant pour les intervenants de la santé que la population générale. Notre relevé mensuel des publications scientifiques qui combinent COVID-19 et sommeil/insomnie entre janvier et juillet 2020 révèle un taux de croissance comparable pour les articles qui portent plus précisément sur la santé mentale mais aucune ne porte sur les résultats d'une intervention...

OBJECTIVE: There is a growing interest in psychiatry regarding melatonin use both for its soporific and chronobiotic effects. This study aimed to evaluate factors impacting the daily-dose. METHODS: In a university department of psychiatry in Paris (France), we conducted a posteriori naturalistic observational study from April 03, 2017 to January 31, 2018. We assessed links between sociodemographic and clinical characteristics and daily dose of melatonin (the daily-dose of melatonin initiation and the daily-dose at Hospital discharge)...
