World Journal of Gastroenterology 2006年第14期12卷 2243-2244页

AIM： To assess the actigraphy, an ambulatory and continuous monitoring of wrist motor activity fitted to study sleep/wake patterns in hepatic encephalopathy （HE）. METHODS： Twenty-five cirrhotic patients （17 M, 8 F, mean age 56± 11 years, 24/25 alcoholic, Child-Pugh A, B, C： 2, 6, 17） were included. The patients were classified into 3 groups： stage 0 group （n = 12）, stage 1-2 group （n = 6）, and stage 3-4 group （n = 7） of encephalopathy. Over three consecutive days, patients had clinical evaluation 3 times a day with psychometric test, venous ammoniemia, flash visually evoked potentials （VEP）, electroencephalogram and continuous actigraphic monitoring for 3 d, providing 5 parameters： mesor, amplitude, acrophase, mean duration of activity （MDAI） and inactivity （MDII） intervals. RESULTS： Serum ammonia and VEP did not differ among the 3 groups. Electroencephalography mean dominant frequency （MDF） correlated significantly with clinical stages of HE （r=0.65, P=0.003）. The best correlation with HE stage was provided by actigraphy especially with MDAI （r= 0.7, P〈10^-4） and mesor （r= 0.65, P〈 10^-4）. MDAI correlated significantly with MDF （r= 0.62, 0.004） and was significantly shorter in case of HE compared to patients without HE （stage 0： 5.33± 1.6 min; stage 1-2：3.28±1.4 min; stage 3-4：2.52±1.1 min; P〈0.05）. Using a threshold of MDAI of less than 4.9 min, sensitivity, specificity, positive predictive value, negative predictive value for HE diagnosis were 85%, 67%, 73% and 80%, respectively. CONCLUSION： Actigraphy may be an objective method to identify HE, especially for early HE detection. Motor activity at the wrist correlates well with clinical stages of HE. MDAI and mesor are the most relevant parameters.

Rational and Continuous Measurement of Emotional-Fingerprint, Emotional-Quotient and Categorical vs Proportional Recognition of Facial Emotions with M.A.R.I.E., Second Half

Open Journal of Psychiatry 2024年第4期14卷 400-450页

Context: The advent of Artificial Intelligence (AI) requires modeling prior to its implementation in algorithms for most human skills. This observation requires us to have a detailed and precise understanding of the interfaces of verbal and emotional communications. The progress of AI is significant on the verbal level but modest in terms of the recognition of facial emotions even if this functionality is one of the oldest in humans and is omnipresent in our daily lives. Dysfunction in the ability for facial emotional expressions is present in many brain pathologies encountered by psychiatrists, neurologists, psychotherapists, mental health professionals including social workers. It cannot be objectively verified and measured due to a lack of reliable tools that are valid and consistently sensitive. Indeed, the articles in the scientific literature dealing with Visual-Facial-Emotions-Recognition (ViFaEmRe), suffer from the absence of 1) consensual and rational tools for continuous quantified measurement, 2) operational concepts. We have invented a software that can use computer-morphing attempting to respond to these two obstacles. It is identified as the Method of Analysis and Research of the Integration of Emotions (M.A.R.I.E.). Our primary goal is to use M.A.R.I.E. to understand the physiology of ViFaEmRe in normal healthy subjects by standardizing the measurements. Then, it will allow us to focus on subjects manifesting abnormalities in this ability. Our second goal is to make our contribution to the progress of AI hoping to add the dimension of recognition of facial emotional expressions. Objective: To study: 1) categorical vs dimensional aspects of recognition of ViFaEmRe, 2) universality vs idiosyncrasy, 3) immediate vs ambivalent Emotional-Decision-Making, 4) the Emotional-Fingerprint of a face and 5) creation of population references data. Methods: M.A.R.I.E. enables the rational, quantified measurement of Emotional Visual Acuity (EVA) in an individual obse
