Self-Reported Violence Experienced by Swiss Prehospital Emergency Care Providers.

Workplace violence is a serious and increasing problem in health care. Nevertheless, only few studies were carried out concerning this topic and then mainly in English-speaking countries. The objectives were to describe the acts of violence experienced by prehospital emergency care providers (PECPs) in the western part of Switzerland between January and December 2016 and to assess the consequences for subsequent PECPs behaviors. An observational cross-sectional study, carried out using an online survey, has been sent to all 416 PECPs in the Canton of Vaud, in the western, French-speaking, part of Switzerland. The survey contained items of demographic data and items to assess the type and consequence of violence sustained. This was classified as five types: verbal assault, intimidation, physical assault, sexual harassment, and sexual assault. 273 (65.6%) PECPs participated in the survey. During 2016, workplace violence was reported by 229 survey participants (83.9%). Most declared to be the victim of such violence between one and three times during the year. In all cases of violence described, the patient and/or a relative initiated aggressive behavior in 96% of cases. Verbal assaults were the most common (99.2% of all acts), followed by intimidation (72.8%), physical assault (69.6%), and sexual harassment (16.3%). Concerning physical assault, PECPs were predominantly victims of spitting and/or jostling (50%). After a violent event, in 50% of cases, the PECPs modified their behavior owing to the experience of workplace violence; 82% now wear protective vests, and 16% carry weapons for self-defense, such as pepper sprays. Seventy-five percent changed their intervention strategies, acting more carefully and using verbal de-escalation techniques or physical restraints for violent patients. Workplace violence is frequent and has significant consequences for PECPs. In order to increase their own security, they increased their protection. These results illustrate their feelings of insecurity, which may have deleterious effects on work satisfaction and motivation. Trial Registration.

Coping with multiple adversities: Men who sought medico-legal care because of physical violence from a partner or ex-partner.

Objectives: To describe male victims of physical violence by an intimate partner who consulted a medico-legal unit, and information available on their perpetrators; to characterize the violent events and their contexts. Little research exists on male victims of physical intimate partner violence seeking medical care. Method: Based on Heise’s ecological framework, mixed methods were used to analyze quantitative and qualitative data collected during 122 medico-legal consultations attended by 115 men who sustained physical violence by an intimate partner from 2006–2012. Results: Quantitative and quantitative data collected from male victims concurred in showing that many of such victims, as well as their partners, faced at the time of the assault multiple adversities and challenges at individual and relationship levels. Among male victims, 26% had no paid job. Among perpetrators, 34% were third-country nationals subject to restricted residence permits. Health issues, worries about money or work combined with complex and conflictive family situations were often in the background of violent events. In a few cases, however, male victims reported no other problems than their partner’s assault. Conclusions: Our findings point out gender-specific aspects of female-to-male physical partner violence. The most common feature is that violence was experienced as one among several adversities. Even though wounds sustained by male victims were not necessarily severe, their emotional suffering was frequent. When underage children were involved, their situation was particularly noteworthy. Interventions with male victims of intimate partner violence should include protection of minors as a priority and as an incentive for fathers to seek help

Effect of growth media modifications on cell biomass and polyunsaturated fatty acids (PUFAs) production from Shewanella frigidimarina

Polyunsaturated fatty acids (PUFAs) are chemically present as esters, ethers, glycerides glycolipids, phospholipids, phosphonolipids, glycosphingolipids, sulpholipids and lipoproteins in storage oils andmembranes lipids. Marine microorganisms such as Shewanella frigidimarina are important sources of polyunsaturated fatty acids with promising biomedical applications, commercial value and the potentialability to be used in the bioremediation of environments contaminated with petroleum hydrocarbons. The growth media dependency of S. frigidimarina in terms of its growth behavior in response to modifications made to the media as well as its potential to produce PUFAs was evaluated. S. frigidimarina was cultured in conventional shake-flasks and controlled bioreactors with a batch-type procedure using different media compositions. The media used included artificial sea water, modifiedartificial sea water 1, modified artificial sea water 2, Luria Bertani, modified Luria Bertani, sodium pyruvate-yeast (PYS) and marine broth. The highest cell biomass was obtained from artificial sea water media with an optical density (OD600) value of 0.15 and subsequent studies were carried out using this medium. To evaluate the potential for PUFA production, RNA transcripts of polyketide synthases (PKS) genes were isolated and reverse-transcriptase polymerase chain reaction (RT-PCR) with S. frigidimarina specific primers carried out. The results of the successful RNA extraction and subsequent RT-PCR revealed that modifications made to growth media compositions can affect the potential for PUFA production.Keywords: Polyunsaturated fatty acids, Shewanella frigidimarina, media modificatio

La prévention et le sexting : un état des lieux

Le développement social et relationnel des adolescent-e-s et des jeunes adultes s’effectue aujourd’hui avec celui d’Internet et des nouvelles technologies. Dans ce contexte, les interactions et la transmission d’informations numériques sont facilitées et peu restreintes, ce qui peut mener à un certain nombre d’enjeux en termes d’usage des technologies et de gestion de l’image numérique. Le sexting fait partie de ces problématiques. Cette pratique pouvant, de manière générale, se définir comme l’échange électronique de matériel personnel à caractère sexuel ou intime, peut parfois mener à des situations dramatiques lorsque, par exemple, le contenu d’un message est transféré sans consentement à d’autres personnes. Après avoir mené une première recherche exploratoire qualitative sur la pratique du sexting chez les jeunes, la thématique de la prévention relative au sexting s’est avérée particulièrement intéressante à approfondir. En effet, très peu de jeunes ont rapporté se rappeler de messages ou campagnes de prévention autour du sexting spécifiquement. Au vu de ces résultats, nous avons considéré qu’il était essentiel d’établir un état des lieux de l’offre préventive sur la thématique du sexting, plus particulièrement dans le canton de Vaud, afin de vérifier les dires de certains jeunes sur le manque d’intervention et de discussion sur le sexting et ses possibles dérives. A travers cet état des lieux et ce rapport, nous proposons donc un catalogue permettant de répertorier et d’offrir une vue d’ensemble des différents acteurs-trices et ressources à disposition dans le cadre de la prévention relative à la pratique du sexting auprès des jeunes

Multipole radiation in a collisonless gas coupled to electromagnetism or scalar gravitation

We consider the relativistic Vlasov-Maxwell and Vlasov-Nordstr\"om systems which describe large particle ensembles interacting by either electromagnetic fields or a relativistic scalar gravity model. For both systems we derive a radiation formula analogous to the Einstein quadrupole formula in general relativity.Comment: 21 page

Current prevalence of self-reported interpersonal violence among adult patients seen at a university hospital emergency department in Switzerland.

To evaluate the current prevalence of self-reported interpersonal violence amongst patients consulting at the emergency department (ED) of a university hospital and to describe the characteristics of the violence sustained. Ours was a cross-sectional study using a modified version of the Partner Violence Screen questionnaire, which was distributed to every patient over 16 years old consulting at the ED between the 1st and 30th September 2016. Excluded were those incapable of decision-making, unable to understand owing to language difficulties, or in police detention. Questions pertained to violence endured during the year prior to their attendance at the ED and, where relevant, the date, place, and type of violence (physical or psychological), the perpetrator and the means used (firearms or other weapons). Demographic details were taken from the hospital records. Of 628 patients included (participation rate 86%), 19% were victims of violence, for 27% of whom it was the motive for ED attendance. The median age of these victims of violence was 28 years (interquartile range 22–43), 39% were female, 71% single and 38% foreign nationals. Typical characteristics of self-reported violence were: (1) violence sustained within the previous 24 h (26%); (2) perpetrators unknown (35%); (3) occurrence at a café, bar, restaurant or nightclub (32%); (4) use of knives (19%); (5) prior consumption of alcohol by the victims themselves (28%). Females were more susceptible to domestic violence than males (45 vs 7%), the latter mostly reporting public violence (64 vs 43% in women). The prevalence of self-reported interpersonal violence has reached one patient in five in our ED. Our results underline the importance of screening for this, as well as providing the means to offer specific follow-up. &nbsp

Decay and Continuity of Boltzmann Equation in Bounded Domains

Boundaries occur naturally in kinetic equations and boundary effects are crucial for dynamics of dilute gases governed by the Boltzmann equation. We develop a mathematical theory to study the time decay and continuity of Boltzmann solutions for four basic types of boundary conditions: inflow, bounce-back reflection, specular reflection, and diffuse reflection. We establish exponential decay in $L^{\infty}$ norm for hard potentials for general classes of smooth domains near an absolute Maxwellian. Moreover, in convex domains, we also establish continuity for these Boltzmann solutions away from the grazing set of the velocity at the boundary. Our contribution is based on a new $L^{2}$ decay theory and its interplay with delicate $$ decay analysis for the linearized Boltzmann equation, in the presence of many repeated interactions with the boundary.Comment: 89 pages

Enfants exposés à la violence dans le couple parental : étude rétrospective des données récoltées auprès de 430 mères et pères de 654 enfants âgés de 0 à 17 ans, lorsque ces parents avaient consulté l’Unité de médecine des violences du CHUV suite à un événement violent dans le couple survenu entre 2011 et 2014

[Préface (extraits)] L'étude menée par l'équipe de l'Unité de médecine des violences (UMV) entrouvre la porte de la chambre des enfants, afin d’amener un éclairage supplémentaire sur la nature et les circonstances de l’exposition des enfants à la violence dans le couple parental. Elle montre comment les enfants sont directement concernés dans la violence qui a lieu dans leur foyer. Souvent atteints psychiquement et physiquement, il n'est pas rare qu'ils aillent jusqu’à s'interposer au milieu de ces rapports de violence en se mettant eux-mêmes en danger lorsqu’ils prennent la défense de la victime, le plus souvent d'ailleurs leur mère. Dans d'autres cas, ils et elles intériorisent les modèles genrés d'auteur ou de victime auprès desquels ils grandissent et puisent leur identité. Les prérequis favorables à une transmission intergénérationnelle de la violence dans le couple sont renforcés par cette immersion quotidienne

Excitation Thresholds for Nonlinear Localized Modes on Lattices

Breathers are spatially localized and time periodic solutions of extended Hamiltonian dynamical systems. In this paper we study excitation thresholds for (nonlinearly dynamically stable) ground state breather or standing wave solutions for networks of coupled nonlinear oscillators and wave equations of nonlinear Schr\"odinger (NLS) type. Excitation thresholds are rigorously characterized by variational methods. The excitation threshold is related to the optimal (best) constant in a class of discr ete interpolation inequalities related to the Hamiltonian energy. We establish a precise connection among $d$, the dimensionality of the lattice, $2\sigma+1$, the degree of the nonlinearity and the existence of an excitation threshold for discrete nonlinear Schr\"odinger systems (DNLS). We prove that if $\sigma\ge 2/d$, then ground state standing waves exist if and only if the total power is larger than some strictly positive threshold, $\nu_{thresh}(\sigma, d)$. This proves a conjecture of Flach, Kaldko& MacKay in the context of DNLS. We also discuss upper and lower bounds for excitation thresholds for ground states of coupled systems of NLS equations, which arise in the modeling of pulse propagation in coupled arrays of optical fibers.Comment: To appear in Nonlinearit
