Objectifs : Le délai door in-door out (DIDO) représente la durée de séjour au service d’urgence (SU) des patients pris en charge pour un syndrome coronarien aigu ST+ (SCAST+), avant transfert en centre de cardiologie interventionnelle (CCI). Le DIDO ne devrait pas dépasser 30 minutes. Notre objectif était d’évaluer le DIDO dans le réseau des urgences Sud Île-de-France (RESSIF).
Matériel et méthodes : Étude épidémiologique, rétrospective, multicentrique comparant le DIDO entre 2014 et 2015 (période 1), puis en 2016 (période 2) dans deux hôpitaux sans CCI, l’hôpital de Longjumeau et l’hôpital d’Arpajon. En 2016 était appliqué dans notre protocole régional SCAST+ le « réflexe électro-oculotéléphonique » (REOT), avec l’objectif de diminuer le DIDO : dès l’électrocardiogramme qualifiant (ECGq), avant tout traitement ou obtention du CCI de transfert, le médecin urgentiste appelle le service d’aide médicale à l’urgence (SAMU) pour l’envoi immédiat d’un service mobile d’urgence et de réanimation (SMUR) secondaire.
Résultats : Entre les deux périodes, le délai DIDO médian n’a pas été modifié significativement (–16 min [4–42] ; p = 0,06). Le délai entre ECGq et appel du SAMU n’était pas significativement différent avant et après application du REOT (15 [8–34] vs 9 min [6–26] ; p = 0,12). Le DIDO était supérieur ou égal à 30 min en période 1, contre 6 % en période 2 (p = 0,11).
Conclusion : Le DIDO du RESSIF n’a pas été significativement modifié. Il n’y a pas eu d’impact significatif du REOT sur le DIDO, mais notre étude manque de puissance. Le REOT pourrait être évalué plus largement dans les SU. Un réseau de soins impliquant les SAMU, SMUR, SU et CCI avec protocoles partagés est essentiel pour le pronostic des SCAST+.

OBJECTIVETraumatic brain injury (TBI)—the “silent epidemic”—contributes to worldwide death and disability more than any other traumatic insult. Yet, TBI incidence and distribution across regions and socioeconomic divides remain unknown. In an effort to promote advocacy, understanding, and targeted intervention, the authors sought to quantify the case burden of TBI across World Health Organization (WHO) regions and World Bank (WB) income groups.METHODSOpen-source epidemiological data on road traffic injuries (RTIs) were used to model the incidence of TBI using literature-derived ratios. First, a systematic review on the proportion of RTIs resulting in TBI was conducted, and a meta-analysis of study-derived proportions was performed. Next, a separate systematic review identified primary source studies describing mechanisms of injury contributing to TBI, and an additional meta-analysis yielded a proportion of TBI that is secondary to the mechanism of RTI. Then, the incidence of RTI as published by the Global Burden of Disease Study 2015 was applied to these two ratios to generate the incidence and estimated case volume of TBI for each WHO region and WB income group.RESULTSRelevant articles and registries were identified via systematic review; study quality was higher in the high-income countries (HICs) than in the low- and middle-income countries (LMICs). Sixty-nine million (95% CI 64–74 million) individuals worldwide are estimated to sustain a TBI each year. The proportion of TBIs resulting from road traffic collisions was greatest in Africa and Southeast Asia (both 56%) and lowest in North America (25%). The incidence of RTI was similar in Southeast Asia (1.5% of the population per year) and Europe (1.2%). The overall incidence of TBI per 100,000 people was greatest in North America (1299 cases, 95% CI 650–1947) and Europe (1012 cases, 95% CI 911–1113) and least in Africa (801 cases, 95% CI 732–871) and the Eastern Mediterranean (897 cases, 95% CI 771–1023). The LMICs experience nearly 3 times more cases of TBI proportionally than HICs.CONCLUSIONSSixty-nine million (95% CI 64–74 million) individuals are estimated to suffer TBI from all causes each year, with the Southeast Asian and Western Pacific regions experiencing the greatest overall burden of disease. Head injury following road traffic collision is more common in LMICs, and the proportion of TBIs secondary to road traffic collision is likewise greatest in these countries. Meanwhile, the estimated incidence of TBI is highest in regions with higher-quality data, specifically in North America and Europe.
Syringobulbia in pediatric patients with Chiari malformation type I

Published: April 2018

OBJECTIVESyringobulbia (SB) is a rare entity, with few cases associated with Chiari malformation type I (CM-I) in the pediatric population. The authors reviewed all pediatric cases of CM-I–associated SB managed at their institution in order to better understand the presentation, treatment, and surgical outcomes of this condition.METHODSA prospectively maintained institutional database of craniovertebral junction abnormalities was analyzed to identify all cases of CM-I and SB from the MRI era (i.e., after 1984). The authors recorded presenting symptoms, physical examination findings, radiological findings, surgical treatment strategy, intraoperative findings, and outcomes. SB cases associated with tumors, infections, or type II Chiari malformations were excluded.RESULTSThe authors identified 326 pediatric patients with CM-I who were surgically treated. SB was identified in 13 (4%) of these 326 patients. Headache and neck pain were noted in all 13 cases. Cranial nerve abnormalities were common: vagus and glossopharyngeal nerve dysfunction was the most frequent observation. Other cranial nerves affected included the trigeminal, abducens, and hypoglossal nerves. Several patients exhibited multiple cranial nerve palsies at presentation. Central sleep apnea was present in 6 patients.Syringomyelia (SM) was present in all 13 patients. SB involved the medulla in all cases, and extended rostrally into the pons and midbrain in 2 patients; in 1 of these 2 cases the cavity extended further rostrally to the cerebrum (syringocephaly). SB communicated with the fourth ventricle in 7 of the 13 cases.All 13 patients were treated with posterior fossa decompression with intradural exploration to ensure CSF egress out of the fourth ventricle and through the foramen magnum. The foramen of Magendie was found to be occluded by an arachnoid veil in 9 cases. Follow-up evaluation revealed that SB improved before SM. Cranial nerve palsies regressed in 11 of the 13 patients, and SB improved in all 13.CONCLUSIONSThe incidence of SB in our surgical series of pediatric patients with CM-I was 4%, and all of these patients had accompanying SM. The SB cavity involved the medulla in all cases and was found to communicate with the fourth ventricle in 54% of cases. Posterior fossa decompression with intradural exploration and duraplasty is an effective treatment for these patients.

OBJECTIVEIncreased understanding of the consequences of traumatic brain injury has heightened concerns about youth participation in contact sports. This study investigated the prevalence of high school and collegiate contact sports play and concussion history among surgical department chairs.METHODSA cross-sectional survey was administered to 107 orthopedic and 74 neurosurgery chairs. Responses were compared to published historical population norms for contact sports (high school 27.74%, collegiate 1.44%), football (high school 10.91%, collegiate 0.76%), and concussion prevalence (12%). One-proportion Z-tests, chi-square tests, and binary logistic regression were used to analyze differences.RESULTSHigh school contact sports participation was 2.35-fold higher (65.3%, p < 0.001) for orthopedic chairs and 1.73-fold higher (47.9%, p = 0.0018) for neurosurgery chairs than for their high school peers. Collegiate contact sports play was 31.0-fold higher (44.7%, p < 0.001) for orthopedic chairs and 15.1-fold higher (21.7%, p < 0.001) for neurosurgery chairs than for their college peers. Orthopedic chairs had a 4.30-fold higher rate of high school football participation (46.9%, p < 0.001) while neurosurgery chairs reported a 3.05-fold higher rate (33.3%, p < 0.001) than their high school peers. Orthopedic chairs reported a 28.1-fold higher rate of collegiate football participation (21.3%, p < 0.001) and neurosurgery chairs reported an 8.58-fold higher rate (6.5%, p < 0.001) compared to their college peers. The rate at which orthopedic (42.6%, p < 0.001) and neurosurgical (42.4%, p < 0.001) chairs reported having at least 1 concussion in their lifetime was significantly higher than the reported prevalence in the general population. After correction for worst possible ascertainment bias, all results except high school contact sports participation remained significant.CONCLUSIONSThe high prevalence of youth contact sports play and concussion among surgical specialty chairs affirms that individuals in careers requiring high motor and cognitive function frequently played contact sports. The association highlights the need to further examine the relationships between contact sports and potential long-term benefits as well as risks of sport-related injury.

Published: April 2018

Abstract
We show that neutron star (NS) binaries can be ideal laboratories to probe hidden sectors with a long-range force. In particular, it is possible for gravitational wave (GW) detectors such as LIGO and Virgo to resolve the correction of waveforms from ultralight dark gauge bosons coupled to NSs. We observe that the interaction of the hidden sector affects both the GW frequency and amplitude in a way that cannot be fitted by pure gravity.

Published: April 2018

Abstract
We report a possible current sheet region associated with a small-scale magnetic reconnection event by using the spectral and imaging observations of the Interface Region Imaging Spectrograph (IRIS) and the magnetograms obtained by the Solar Dynamics Observatory on 2016 August 08. The length and width of the current sheet region are estimated to be from 1.4 ± 0.1 Mm to 3.0 ± 0.3 Mm and from 0.34 ± 0.01 Mm to 0.64 ± 0.09 Mm, respectively. The evolutions of the length of the current sheet region are positively correlated with that of the width. These measurements are among the smallest reported. When the IRIS slit scans the current sheet region, the spectroscopic observations show that the Si iv line is broadened in the current sheet region and the plasma has a blueshifted feature at the middle and a redshifted feature at the ends of the current sheet region. The maximum measured blueshifted and redshifted Doppler velocities are −20.8 ± 0.9 and 34.1 ± 0.4 km s−1, respectively. Additionally, the electron number densities of the plasma in the current sheet region are computed to be around 1011 cm−3 based on the spectrums of the two O iv lines. The emergence, movement, and cancellation of a small sunspot with negative polarity are observed during the formation and shift of the current sheet region. We suggest that the occurrence and evolution of the magnetic reconnection are driven by the movement of the small sunspot in the photosphere.
L’héroïsme de la femme dans l’épopée africaine : un regard critique de <i>Soundjata ou l’épopée mandingue, Emperor Shaka The Great : A Zulu Epic</i> et <i>Nsongo’a Lianja : l’épopée nationale des Nkundo</i>
Authors: Mukenge Arthur , Nkaongami Josue B. 
Published: April 2018

The Heroism of women in the African Epic: A critical analysis of Sundiata or the mandingo Epic, Emperor Shaka The Great: A Zulu Epic and Nsongo’a Lianja: The national Epic of the Nkundo. In African epics, female figures perform salient heroic roles that are, unfortunately, not widely recognised and celebrated, as notions of bravery and heroism are understood from a male perspective. Against this backdrop, this study adopts new critical and conceptual approaches to interrogate existing narratives, discourse and ideas on/or about female heroism. By focusing on selected epics, this work incorporates perceptions about women in folktales whose themes comment and reflect on the presentation of female characters and the roles they execute in society. The present contribution critically examines the role of supernatural forces in female characters’ commitment and heroism; not only protecting Soundiata, Shaka, and Lianja in accomplishing their destinies but also showcasing the activities, traditions, belief systems and culture of the Mandingo, Zulu, and Mongo in their respective societies.
Management perceptions regarding factors impacting privatisation of parastatals in a developing country
Authors: Mazibuko Noxolo E. , Smith Elroy E. , Tshuma Eddie 
Published: April 2018

Background: Worldwide, the ownership of public organisations has been transferred to the private sector through privatisation. The poor performance of public organisations has necessitated privatisation of these organisations. Aim: This article explored management perceptions regarding factors impacting the privatisation of parastatals in a developing country, namely Zimbabwe. Setting and method: A comprehensive literature study provided the theoretical framework for this research. Primary data were collected by means of a survey obtaining 301 self-administered structured questionnaires from 27 parastatals in Zimbabwe. Seven null-hypotheses were tested using advanced statistical techniques such as regression and correlation analyses. Results and conclusions: Factors identified in this study that could impact privatisation of parastatals in Zimbabwe are stakeholder consultation, stable macroeconomic conditions, government transparency and a well-developed privatisation process plan. If privatisation is implemented effectively, it could lead to increased organisational performance, effective governance and economic empowerment. It also appeared that variables such as union consultation, role ambiguity, political intervention, attractiveness to foreign investment and government commitment do not exert a significant influence on perceptions of privatisation. Practical guidelines were also provided to enhance the implementation of privatisation in parastatals.
The subjective well-being of day labourers in South Africa: The role of income and geographical location
Authors: Blaauw Phillip F. , Botha Ilse , Schenck Catherina 
Published: April 2018

Background: The informal economy in South Africa provides employment to large numbers of people who would otherwise have no opportunity to earn a living. Yet informal activities, such as day labouring, generate highly uncertain returns. Although it seems reasonable to conclude that day labourers would be dissatisfied with their lives, this is not necessarily the case as several factors contribute to people’s subjective well-being. Aim: This study is in response to a call for more research on the subjective well-being of marginalised groups in South Africa’s informal labour market. Setting: The day labour market in South Africa, whose members congregate at hiring sites hoping to be picked up by passers-by in need of temporary, casual workers. Methods: Using Sen’s Capability Approach, the study builds on earlier research conducted on the general well-being of day labourers in South Africa, with specific focus on their subjective well-being and geographical location. The results from a countrywide survey of 3830 day labourers were used in a regression analysis to compare the subjective well-being among day labourers across the nine provinces of South Africa. Results: There are statistically significant differences in the well-being of day labourers across the nine provinces. Economic variables play a role in both objective and subjective measures of well-being, while attitudinal and comparison variables are significant for the objective and subjective measures, respectively. Conclusions: Although they have to operate in harsh conditions, day labourers in South Africa display agency by choosing to migrate to richer provinces in search of greater economic opportunity and reward. However, these potential gains are often negated by increased levels of competition and thus depressed wage levels. How to nurture marginalised groups’ abilities to exercise agency and take more control of their lives represents fertile ground for researchers in future.
