Évaluation assistée par IA des psychotraumatismes liés aux lahars dans la commune du Prêcheur aux Antilles françaises
Authors: Jehel Louis , Guidère Mathieu 
Published: July 2024

Objectifs Les catastrophes naturelles ont des conséquences importantes sur la santé mentale. Les données recueillies auprès de la population offrent une occasion unique de surveillance après les catastrophes pour aider à identifier les besoins de soutien psychologique. L’objectif de cette étude est : 1) d’identifier les aspects psychopathologiques pour la commune du Prêcheur soumise au risque de lahars (laves volcaniques) ; et 2) de phénotyper les aspects psychopathologiques à partir des données recueillies auprès de la population.
Méthode Nous avons appliqué une méthode de psychophénotypage assistée par l’intelligence artificielle (IA) sur les données de 40 personnes sur une durée de 20 mois, pour extraire les aspects psychopathologiques et psychiatriques liés aux aléas naturels traumatisants (lahars). Ensuite, nous les avons comparées aux résultats de tests psychométriques mesurant l’état global de santé mentale ainsi que l’état de stress posttraumatique.
Résultats La rumination et la négativation figuraient parmi les aspects psychopathologiques les plus importants identifiés. De plus, nous avons noté la présence de la reviviscence et de l’évitement comme dimensions psychiatriques de base au fil du temps. Parmi celles-ci, l’évitement cognitif et l’évitement émotionnel ont été identifiés et semblent avoir émergés après la catastrophe.
Conclusion Nous avons proposé une nouvelle approche de surveillance syndromique pour la santé mentale basée sur les données numériques qui peut soutenir les approches conventionnelles en fournissant des informations supplémentaires utiles dans le contexte d’une catastrophe. D’autres études sont nécessaires pour mieux contrôler les biais, identifier les associations avec des instruments valides et explorer des méthodes de calcul pour un ajustement continu du modèle d’analyse assisté par IA.

Authors: Echater Sara , Hasnaoui Mohammed , Barrimi Mohammed 
Published: July 2024

Introduction L’usage des substances psychoactives chez les médecins résidents est un problème sous-estimé, mal connu et grave en raison de ses conséquences négatives sur la santé des médecins ainsi que pour la santé et la sécurité des patients dont ils ont la charge.
Objectif L’objectif de ce travail est d’étudier la prévalence et les facteurs associés à la consommation des substances psychoactives (SPA) chez les médecins résidents au niveau des différents centres hospitaliers universitaires du Maroc.
Méthode Nous avons réalisé une étude transversale multicentrique descriptive et analytique portant sur les médecins résidents des 7 centres hospitaliers universitaires du Maroc. Les médecins résidents ont été sollicités à participer de manière volontaire en remplissant un autoquestionnaire anonyme sur Google Forms, lequel leur a été envoyé par courriel.
Résultats Le questionnaire a été rempli par 310 médecins résidents, soit 11,07 % de la population totale des médecins résidents au Maroc. Parmi les participants, 16,1 % (n = 50) ont déclaré consommer une ou plusieurs substances psychoactives, dont 11,1 % (n = 37) du tabac, 10 % (n = 31) de l’alcool et 6,1 % (n = 19) du cannabis. Les consommations d’ectasy et de cocaïne ont été observées chez 0,7 % (n = 2) pour chaque substance. En outre, 11,9 % (n = 37) des médecins résidents ont des troubles psychiatriques, et 3,2 % (n = 10) ont déjà fait au moins une tentative de suicide. La consommation de substances psychoactives chez les médecins résidents était statistiquement significativement associée au sexe masculin (4,59 [2,20-9,57] ; p = 0,000), ainsi qu’à la spécialité chirurgicale (0,48 [0,26-0,88] ; p = 0,017).
Conclusion Au terme de ce travail, nous avons constaté que la consommation des substances psychoactives est fréquente chez les médecins résidents d’où la nécessité des mesures de prévention et de soutien adaptées pour ces derniers.

Background
Non-alcoholic fatty liver disease (NAFLD) is intricately linked with dietary patterns and metabolic homeostasis. Therefore, the present study focused to investigate the relation between dietary patterns and cardiometabolic risk factors related to fatty liver in NAFLD patients.

Methods
This cross-sectional study included 117 individuals whose body mass index (BMI) threshold of 25 or above diagnosed with NAFLD by magnetic resonance imaging. The hospital database was used to review the patients’ medical records such as lipid parameters, and fasting blood sugar. Anthropometric measurements and body composition were measured by researchers. Likewise, data from 24-h dietary recalls of individuals were collected to analyze their energy and nutrient intakes besides calculating dietary insulin index (DII), dietary insulin load (DIL), dietary glycemic index (DGI), and dietary glycemic load (DGL).

Results
Participants consuming diets with distinct levels of DII, DIL, DGI, and DGL exhibited variations in dietary energy and nutrient intake. Specifically, differences were noted in carbohydrate intake across quartiles of DII, DIL, DGI, and DGL, while fructose consumption showed variability in DGL quartiles (p ≤ 0.05). Moreover, sucrose intake demonstrated distinctions in both DII and DGL quartiles (p ≤ 0.05). No statistical difference was found in biochemical parameters and the fatty liver index among different levels of DII, DIL, DGI, and DGL (p > 0.05). After adjusting for potential confounders, participants with a higher DGI had four times greater odds of developing metabolic syndrome compared to those in the bottom quartile (OR, 4.32; 95% CI [1.42–13.11]).

Conclusion
This study provides initial evidence of the intricate association between dietary factors and NAFLD, emphasizing the necessity for further research including prospective designs with larger sample sizes, to garner additional insights.
Acute effects of voluntary isometric contractions at maximal shortening vs. ballistic stretching on flexibility, strength and jump
Authors: Hernández-Trujillo J. Artemi , González-Rivera María Dolores , Romero-Franco Natalia , González-Hernández Jorge M. 
Published: July 2024

Background
Isometric training is used in sport, conventional physical activity and rehabilitation. Understandably, there is a great deal of research related to its effect on performance. It is known that the length of the muscle at the moment of contraction is a determinant of strength levels. In the literature we find research on isometric training in short muscle lengths, although it has not been studied in maximally shortened positions or the acute effects that occur after its application. Ballistic stretching (BS) is also popular in sport. Their execution involves actively reaching maximally shortened muscle positions. So far, isometric training has not been compared with protocols involving ballistic stretching. Considering the above, the aim of the present study was to investigate the effects of BS and voluntary isometric contraction at maximal shortening (VICAMS) on range of motion, strength and vertical jump.

Methods
The study involved 60 healthy, physically active individuals (40 and 52 years old) who were randomly assigned to three groups: BS, VICAMS and a control group (CG). To assess acute effects, before and after the intervention, active range of motion (AROM), maximal voluntary isometric force (MVIF) and countermovement jump height (CMJ) were determined.

Results
Time main effects and time*group interactions were found for all variables (p < 0.001). Between-group differences were shown for the VICAMS group after the intervention, with statistically significant higher AROM values compared to the other groups. MVIF values were also higher in the VICAMS group. Intra-group differences were observed for the VICAMS and Ballistic groups, as values on all variables increased from baseline. For the CMJ, intra-group differences showed that both the VICAMS and BS groups improved values compared to baseline values.

Conclusions
The application of VICAMS induced acute improvements over BS in AROM, MVIF and CMJ. These results are important for coaches seeking immediate performance improvement and offer an optimal solution to the warm-up protocol.
Reducing nonuniqueness in finite source inversion using rotational ground motions
Authors: Bernauer M. , Fichtner A. , Igel H. 
Published: May 2014

AbstractWe assess the potential of rotational ground motion recordings to reduce nonuniqueness in kinematic source inversions, with emphasis on the required measurement accuracy of currently developed rotation sensors. Our analysis is based on synthetic Bayesian finite source inversions that avoid linearizations and provide a comprehensive quantification of uncertainties and trade‐offs. Using the fault and receiver geometry of the Tottori 2000 earthquake as a test bed, we perform inversions for two scenarios: In scenario I, we use translational velocity recordings only. In scenario II, we randomly replace half of the velocity recordings by rotation recordings, thus keeping the total amount of data constant. To quantify the noise‐dependent impact of rotation recordings, we perform a sequence of inversions with varying noise levels of rotations relative to translations. Our results indicate that the incorporation of rotational ground motion recordings can significantly reduce nonuniqueness in finite source inversions, provided that measurement uncertainties are similar to or below the uncertainties of translational velocity recordings. When this condition is met, rupture velocity and rise time benefit most from rotation data. The trade‐offs between both parameters are then strongly reduced, and the information gain nearly doubles. This suggests that rotational ground motion recordings may improve secondary inferences that rely on accurate information about rise time and rupture velocity. These include frictional properties of the fault, radiation directivity, and ground motion in general.

AbstractThis paper presents the NOW regional coupled ocean‐atmosphere model built from the NEMO ocean and WRF atmospheric numerical models. This model is applied to the tropical Indian Ocean, with the oceanic and atmospheric components sharing a common ¼° horizontal grid. Long experiments are performed over the 1990–2009 period using the Betts‐Miller‐Janjic (BMJ) and Kain‐Fritsch (KF) cumulus parameterizations. Both simulations produce a realistic distribution of seasonal rainfall and a realistic northward seasonal migration of monsoon rainfall over the Indian subcontinent. At subseasonal time scales, the model reasonably reproduces summer monsoon active and break phases, although with underestimated rainfall and surface wind signals. Its relatively high resolution results in realistic spatial and seasonal distributions of tropical cyclones, but it fails to reproduce the strongest observed cyclone categories. At interannual time scales, the model reproduces the observed variability associated with the Indian Ocean Dipole (IOD) and the delayed basin‐wide warming/cooling induced by the El Niño Southern Oscillation (ENSO). The timing of IOD occurrence in the model generally matches that of the observed events, confirming the influence of ENSO on the IOD development (through the effect of lateral boundary conditions in our simulations). Although the KF and BMJ simulations share a lot in common, KF strongly overestimates rainfall at all time scales. KF also overestimates the number of simulated cyclones by a factor two, while simulating stronger events (up to 55 m s−1) compared to BMJ (up to 40 m s−1). These results could be related to an overly active cumulus parameterization in KF.

Published: May 2014

ObjectiveTactile spatial acuity is routinely tested in neurology to assess the state of the dorsal column system. In contrast, spatial acuity for pain is not assessed, having never been systematically characterized. More than a century after the initial description of tactile acuity across the body, we provide the first systematic whole‐body mapping of spatial acuity for pain.MethodsWe evaluated the 2‐point discrimination thresholds for both nociceptive‐selective and tactile stimuli across several skin regions. Thresholds were estimated using pairs of simultaneous stimuli, and also using successive stimuli.Results and interpretationThese two approaches produced convergent results. The fingertip was the area of highest spatial acuity, for both pain and touch. On the glabrous skin of the hand, the gradient of spatial acuity for pain followed that observed for touch. On the hairy skin of the upper limb, spatial acuity for pain and touch followed opposite proximal–distal gradients, consistent with the known innervation density of this body territory. Finally, by testing spatial acuity for pain in a rare participant completely lacking Aβ fibers, we demonstrate that spatial acuity for pain does not rely on a functioning system of tactile primary afferents. This study represents the first systematic characterization of spatial acuity for pain across multiple regions of the body surface. Ann Neurol 2014;75:917–924

Authors: Wen Zhenhai , Ci Suqin , Hou Yang , Chen Junhong 
Published: May 2014

AbstractA one‐pot/one‐step synthesis strategy was developed for the preparation of a nitrogen‐doped carbon nanoarchitecture with graphene‐nanosheet growth on the inner surface of carbon nanotubes (CNTs). The N‐graphene/CNT hybrids exhibit outstanding electrocatalytic activity for several important electrochemical reactions as a result of their unique morphology and defect structures, such as high but uniform nitrogen doping, graphene insertion into CNTs, considerable surface area, and the presence of iron nanoparticles. The high‐yield synthetic process features high efficiency, low‐cost, straightforward operation, and simple equipment.

Published: May 2014

ABSTRACTThe fundamental rheological properties of a wide molar mass Mw range of poly(butylene succinate)s (PBSs) are investigated. For entangled samples and a reference temperature of 140°C, the shear viscosity is described by the Carreau–Yasuda model. The plateau modulus is estimated at 1.5 × 105 Pa, the average activation energy of PBS melt is
, and the critical molar mass for entanglement Mc is found to be 16,000 g mol−1 (PS equivalent). The dilute solution properties of PBS are also studied. A size exclusion chromatography equipped with a triple detection system is used to estimate the Mark–Houwink–Sakurada (MHS) parameters of PBS in solution in chloroform at 30°C. The exponent a and the coefficient K of the MHS relationship are found to be 0.71 ± 0.1 and 39.94 × 10−5 ± 6.31 × 10−5 dL g−1(g mol−1)−a, respectively. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

Authors: Pan Xiaoyong , Peng Ling , Liu Yong , Wang Jie 
Published: May 2014

ABSTRACTIn this work, high‐performance multifunctional composites were obtained by melt blending silver deposited tetrapod‐like zinc oxide whiskers (Ag‐ZnOw) with polystyrene (PS). The chemical, spectroscopic, antibacterial, mechanical, and morphological properties of the PS/Ag‐ZnOw composites were carefully investigated and discussed. The obtained PS/Ag‐ZnOw composites characterized remarkable antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Moreover, it is found that impact strength of the composite increase with increasing nanofiller concentration (up to 0.25 wt %). Morphological characterization of the impact fractured surface of composites revealed that toughening was achieved through uniform filler distribution in the polymer matrix, and anchoring effect was imparted by the tetrapod‐like shape of ZnO whiskers. © 2014 Wiley Periodicals, Inc.

Spectrofluorimetric analysis of ethopabate in veterinary formulations with application to residue determination in chicken muscles and liver
Authors: Nasr Jenny Jeehan , Shalan Shereen 
Published: May 2014

ABSTRACTEthopabate is a veterinary drug used in the prophylaxis and treatment of coccidiosis in chickens. The presence of drug residues in edible tissues can be dangerous to human consumers. It may cause direct toxic effects, allergic reactions and increased bacterial resistance. A highly sensitive, simple and rapid spectrofluorimetric method was developed for the determination of ethopabate in its veterinary formulations. The proposed method is based on measuring the native fluorescence of ethopabate in water at 364 nm after excitation at 270 nm. The fluorescence–concentration plot was rectilinear over the range of 2–100 ng/mL, with a limit of detection of 2.9 ng/g and a limit of quantification of 9.8 ng/g for ethopabate. The method was successfully applied to the analysis of ethopabate in its commercial veterinary formulations and the results were in good agreement with those obtained with the reference method. The method was extended to the determination of ethopabate residues in chicken muscles and liver, and the results were satisfactory. The recoveries obtained were in the 108.36–113.42% range. No organic solvents are used in the procedure, so it can be considered a type of ‘green’ chemistry. Copyright © 2014 John Wiley & Sons, Ltd.

ABSTRACTThe objective of this study was to isolate antimicrobial peptides from Capsicum baccatum seeds and evaluate their antimicrobial activity and inhibitory effects against α‐amylase. Initially, proteins from the flour of C. baccatum seeds were extracted in sodium phosphate buffer, pH 5.4, and precipitated with ammonium sulfate at 90% saturation. The D1 and D2 fractions were subjected to antifungal tests against the yeasts Saccharomyces cerevisiae, Candida albicans, Candida tropicalis, and Kluyveromyces marxiannus, and tested against α‐amylases from Callosobruchus maculates and human saliva. The D2 fraction presented higher antimicrobial activity and was subjected to further purification and seven new different fractions (H1–H7) were obtained. Peptides in the H4 fraction were sequenced and the N‐terminal sequences revealed homology with previously reported storage vicilins from seeds. The H4 fraction exhibited strong antifungal activity and also promoted morphological changes in yeast, including pseudohyphae formation. All fractions, including H4, inhibited mammalian α‐amylase activity but only the H4 fraction was able to inhibit C. maculatus α‐amylase activity. These results suggest that the fractions isolated from the seeds of C. baccatum can act directly in plant defenses against pathogens and insects. © 2014 Wiley Periodicals, Inc.

ABSTRACTAn unprecedented complementarity of electronic circular dichroism (ECD) and vibrational circular dichroism (VCD) spectroscopic techniques is demonstrated by showing that each technique reveals the structure of a different molecular segment. Using a flexible molecule of biological significance we show that the synergetic use of ECD and VCD yields more complete structural characterization as it provides improved and more reliable conformer resolution.
