Published: April 2022

BackgroundGiven the scarcity of resources, the increasing use of emergency departments (ED) represents a major challenge for the care of emergency patients. Current health policy interventions focus on restructuring emergency care with the help of patient re-direction into outpatient treatment structures. A precise analysis of ED utilization, taking into account treatment urgency, is essential for demand-oriented adjustments of emergency care structures.MethodsTemporal and seasonal trends in the use of EDs were investigated, considering treatment urgency and hospital mortality. Secondary data of 287,119 ED visits between 2015 and 2017 of the two EDs of Charité Universitätsmedizin Berlin, Campus Charité Mitte and Campus Virchow Klinikum were analyzed.ResultEDs were used significantly more frequently on weekends than on weekdays (Mdn = 290 vs. 245 visits/day; p &lt; 0.001). The proportion of less urgent, outpatient emergency visits on weekends was above average. Holiday periods were characterized by at least 6, and at most 176 additional ED visits. In a comparison of different holidays, most ED visits were observed at New Year (+68% above average). In addition, a significant increase in in-hospital mortality on holidays was evident among inpatients admitted to hospital via the ED (3.0 vs. 3.2%; p &lt; 0.001), with New Year's Day being particularly striking (5.4%).ConclusionThese results suggest that, in particular, the resource planning of outpatient emergency treatment capacities on weekends and holidays should be adapted to the increased volume of non-urgent visits in EDs. Nevertheless, treatment capacities for the care of urgent, inpatient emergencies should not be disregarded and further research projects are necessary to investigate the causes of increased mortality during holiday periods.

Published: April 2022

IntroductionA reproducible, standardised model for cutaneous scar tissue to assess therapeutics is crucial to the progress of the field. A systematic review was performed to critically evaluate scarring models in both animal and human research.MethodAll studies in which cutaneous scars are modelling in animals or humans were included. Models that were focused on the wound healing process or those in humans with scars from an existing injury were excluded. Ovid Medline® was searched on 25 February 2019 to perform two near identical searches; one aimed at animals and the other aimed at humans. Two reviewers independently screened the titles and abstracts for study selection. Full texts of potentially suitable studies were then obtained for analysis.ResultsThe animal kingdom search yielded 818 results, of which 71 were included in the review. Animals utilised included rabbits, mice, pigs, dogs and primates. Methods used for creating scar tissue included sharp excision, dermatome injury, thermal injury and injection of fibrotic substances. The search for scar assessment in humans yielded 287 results, of which 9 met the inclusion criteria. In all human studies, sharp incision was used to create scar tissue. Some studies focused on patients before or after elective surgery, including bilateral breast reduction, knee replacement or midline sternotomy.DiscussionThe rabbit ear scar model was the most popular tool for scar research, although pigs produce scar tissue which most closely resembles that of humans. Immunodeficient mouse models allow for in vivo engraftment and study of human scar tissue, however, there are limitations relating to the systemic response to these xenografts. Factors that determine the use of animals include cost of housing requirements, genetic traceability, and ethical concerns. In humans, surgical patients are often studied for scarring responses and outcomes, but reproducibility and patient factors that impact healing can limit interpretation. Human tissue use in vitro may serve as a good basis to rapidly screen and assess treatments prior to clinical use, with the advantage of reduced cost and setup requirements.

Published: April 2022

BackgroundVideo-assisted thoracoscopic surgery (VATS) has been widely performed for patients with lung cancer. Splenic rupture after VATS lung procedures is a very rare and serious event.Case PresentationWe reported a case with hemodynamic instability after left lower VATS lobectomy. There was no evidence of diaphragmatic injury during the surgery. Computed tomography (CT) showed spleen injury and large amount of fluid in the abdominal cavity. Emergent laparotomy was performed, and splenic rupture was diagnosed. The patient underwent splenectomy, with two lacerations at the diaphragmatic surface of the spleen. The patient did well postoperatively and was discharged from the hospital on postoperative day 5.ConclusionThere are few similar cases reported in the literature. Persistent hemodynamic instability due to the rupture of spleen is life-threatening. In the situation of unexplained hypotension during VATS procedures (especially left-sided approaches), the possibility of splenic injury and rupture should be considered. Abdominal ultrasonography and/or CT examinations should be carried out for prompt diagnosis and treatment of such rare complication.

Published: April 2022

Objectives: Radon, a radioactive gas, is among the leading causes of lung-cancer worldwide. While public health authorities emphasize radon’s health risks, there are spas across Europe which claim health benefits of radon. This study investigates how websites of European radon spas frame radon gas, in order to understand the potential controversy between “radon as carcinogen” and “radon as cure,” and its potential impact on public health interventions.Methods: A two-phased frame analysis of websites of radon spas (n = 26) situated in the European Union.Results: Five frames are identified, which present radon as a 1) source of health, 2) natural gas, 3) (non) risk, 4) luxury and 5) fountain of youth. These five partly overlapping frames are at times in clear contrast with the ways in which radon is presented in a public health context.Conclusion: Being aware of the existence and contents of radon frames, which potentially challenge or contradict public health interventions, helps responsible authorities in designing more effective campaigns and interventions.

Résumé introductif Il s’agissait dans le cas de cette étude d’explorer par une technique d’associations verbales comment des entraîneurs et des jeunes joueurs percevaient l’idée de cohésion, avec l’hypothèse largement vérifiée par ailleurs que les mots que les sujets associent à certains phénomènes, comme la cohésion dans l’équipe entre autres, pourraient être considérés comme porteurs des traces (d’indicateurs) de l’univers représentationnel des sujets et des opérations cognitives sous-jacentes. L’étude a consisté en un recueil de données qui visait à mettre au jour les différents lexèmes (mots) utilisés par des entraîneurs et des jeunes joueurs pour exprimer l’idée de « cohésion dans l’équipe ». L’échantillon (N = 480) était composé de 240 entraîneurs et de 240 joueurs de 14/17 ans. À l’aide de classifications ascendantes hiérarchiques (méthode de Ward) nos résultats sont présentés sous forme de dendogrammes et laissent apparaître que les entraîneurs perçoivent la cohésion au travers de comportements nettement interactifs (parler, communiquer et échanger). Quant aux jeunes joueurs ils expriment la cohésion surtout à travers des sentiments tels qu’être indulgents, disciplinés, compréhensifs, respectueux, solidaires et soudés .

Résumé introductif Ce chapitre explore le lien entre le langage et l’identité sociale (Tajfel, 1978, 1981 ; Tajfel et Turner, 1979) à travers le concept de marqueurs socio-langagiers (Scherer et Giles, 1979). Les deux études présentées portent sur l’effet des marqueurs socio-lexicaux sur les attitudes des participants, selon qu’elles soient structurées préalablement ou non. Les résultats mettent en évidence 1/ l’emploi de lexiques différents selon le groupe d’appartenance du locuteur ; 2/ un effet des marqueurs socio-lexicaux dans la construction d’opinion ; 3/ un effet des marqueurs socio-lexicaux, proche d’une menace de l’identité sociale, dans le cas d’attitude structurée par une appartenance groupale. Les implications théoriques et appliquées de ces résultats sont discutées .
Une cartographie des recrutements du personnel de la banque centrale européenne en temps de crise (2005-2011)
Authors: Dufour Julien 
Published: April 2022

La crise financière de 2007-2009 survient dans un contexte de ralentissement des recrutements du personnel de la Banque centrale européenne (BCE) en comparaison des périodes précédentes marquées par son déploiement institutionnel. De par son ampleur mondiale et son intensité, elle suscite un accroissement considérable de la charge de travail de son personnel et conduit l’institution à accroître sensiblement le rythme de ses recrutements. L’analyse des profils recrutés donne à voir un espace social spécifique, préfigurant notamment l’un des changements institutionnels majeurs qu’est l’ajout de la surveillance bancaire en 2014.
Pediatric Eyelid and Canalicular Lacerations: Epidemiology and Outcomes
Authors: Huang Jonathan , Rossen Jennifer , Rahmani Bahram , Mets-Halgrimson Rebecca 
Published: April 2022

Purpose:
To characterize the epidemiology of eyelid lacerations, identify risk factors for canalicular involvement, and describe postoperative complications following laceration repair.

Methods:
All patients undergoing eyelid laceration repair at a tertiary care, level I trauma center children's hospital from November 2010 to April 2021 were identified by a Current Procedural Terminology code search. Patient characteristics, surgical characteristics, and surgical outcomes were collected via chart review. Univariate analysis and multivariate logistic regression were performed to identify risk factors for canalicular involvement and postoperative complication.

Results:
A total of 165 patients were identified, of whom 136 had at least 1 week of follow-up and were further assessed for postoperative complications. The most common mechanisms of injury were dog bites (62, 38%), falls (33, 20%), and being struck by an object (22, 13%). Eyelid margin involvement was present in 108 patients (65%) and canalicular involvement in 77 patients (47%). Risk factors for canalicular involvement were hook-related injury, eyelid margin involvement, and lower eyelid injury. Thirty-three patients (24%) had postoperative complications, most commonly ptosis (7, 5%), premature stent loss (7, 5%), and eyelid margin notching (6, 4%). There was no association between postoperative complication and antibiotic use, delayed repair, or wound class.

Conclusions:
Hook-related injury, eyelid margin involvement, and lower eyelid injury are risk factors for canalicular involvement. Postoperative complications of eyelid lacerations are generally minor and are not associated with perioperative factors. Close postoperative follow-up is needed to monitor for complication development.

Sandhill Crane Colt Survival in Minnesota
Authors: Severud William J. , Wolfson David , Fieberg John , Andersen David E. 
Published: April 2022

Abstract
Age-structured population models require reliable estimates of cohort-specific survival rates, yet vital rates of younger age classes are often difficult to estimate because of the logistical challenges of monitoring young animals. As part of a study of sandhill cranes Antigone canadensis in the zone of contact between breeding distributions of the Eastern Population and Midcontinent Population in Minnesota, we monitored first summer survival of 34 sandhill cranes (hereafter colts) by using very-high-frequency and global positioning system–global system for mobile communications transmitters. We estimated daily survival probabilities from 19 to 120 d posthatch by using a generalized linear model accounting for interval censoring, resulting in an estimated period survival rate of 0.52 (90% CI, 0.36–0.71) over summer (100 d). Estimated daily probabilities of survival increased as colts became older and fledged (at 70–75 d posthatch), when they presumably became less vulnerable to predation. Causes of mortality were mostly unknown aside from one case of a collision with a vehicle. There is a scarcity of published colt survival rate estimates for sandhill cranes, and what is available varies widely by study site. Region-specific sandhill crane colt survival rate estimates can inform future management efforts and inform population dynamics research and overall natural history knowledge of sandhill cranes.

La Côte d’Ivoire s’est engagée, avec l’appui de ses partenaires techniques et financiers, dans un ambitieux programme de construction de petits collèges ruraux, dits « de proximité » (moins de 5 km de trajet), afin de répondre à la croissance rapide des effectifs en 6ème et de réduire les inégalités villes-campagnes. La loi instituant la scolarité obligatoire jusqu’à 16 ans (2015) fait du collège le cycle terminal de l’école de base et induit une réforme profonde, dont les collèges de proximité sont le laboratoire et la préfiguration.
Homocysteine and atrial fibrillation: novel evidences and insights
Authors: Ivanov Valeriy , Smereka Yuliia , Rasputin Volodymyr , Dmytriiev Kostiantyn 
Published: April 2022

Atrial fibrillation (AF) is one of the most prevalent rhythm disorders worldwide, with around 37.574 million cases around the globe (0.51 % global population). Different studies showed a high informative value of different biomarkers, including such related to the systemic inflammation, biomechanical stress and fibrosis. In this review article we aimed to study only the relation of homocysteine to the AF development. Homocysteine is a sulfur-containing amino acid, that is produced in the process of methionine metabolism. Which is a non-canonical amino acid, that is derived from the food proteins. From the scientific point of view there is a relation between hyperhomocysteinemia and myocardial fibrosis, but these mechanisms are complicated and not sufficiently studied. Homocysteine regulates activity of the ion channels through their redox state. Elevated homocysteine level can condition electrical remodeling of the cardiomyocytes through the increase of sodium current and change in the function of rapid sodium channels, increase of inwards potassium current and decrease in amount of rapid potassium channels. High homocysteine concentration also leads to the shortening of the action potential, loss of the rate adaptation of the action potential and persistent circulation of the re-entry waves. In a series of experimental studies on mice there was an association found between the homocysteine level and activity of vascular inflammation. Elevation of homocysteine level is an independent factor of the thromboembolic events and AF relapses. Population studies showed, that homocysteine is an independent risk factor for AF. So, homocysteine is an interesting target for up-stream therapy.
