La santé des travailleurs âgés en Europe
Authors: Sirven Nicolas , Sermet Catherine 
Published: March 2021

Cette étude propose de dresser un bilan de l’état de santé des travailleurs âgés entre 50 et 60 ans dans 14 pays européens, à partir des données individuelles de l’enquête Share (2006-2007). L’analyse procède à des comparaisons internationales en s’appuyant sur plusieurs mesures de l’état de santé – objectives et subjectives – , et pour lesquelles l’effet confondant des caractéristiques sociodémographiques est pris en compte. Bien que le recours à plusieurs mesures de santé ne permette pas de dégager un schéma européen bien tranché, deux résultats principaux émergent. D’une part, on constate une importante hétérogénéité des situations entre les pays d’Europe en matière d’état de santé des travailleurs de 50-59 ans. D’autre part, les actifs occupés français comptent parmi les travailleurs de 50-59 ans les plus souvent en mauvaise santé.
L’insomnie et son double littéraire, figure de l’inquiétante étrangeté
Authors: Le Toullec Éric 
Published: March 2021

En psychanalyse, la dimension symptomatique de l’insomnie ne peut aller de soi, il s’agit d’en élucider le sens caché et d’interroger sa dimension inconsciente. Car l’insomnie met en échec toute forme d’interprétation immédiate. Alors, de quoi vient-elle nous parler ? L’hypothèse d’une écriture de l’insomnie dans les formations de l’inconscient nous permet d’en aborder la problématique dans les champs conjoints de la clinique et de la littérature. À partir d’une nouvelle d’Alice Munro, extraite de son dernier recueil intitulé Rien que la vie ( Dear Life, 2012 en anglais), nous avons étudié la relation entre l’insomnie d’une adolescente et la question de la castration dans son rapport au père. « Nuit » – c’est le titre de la nouvelle – fait également référence au texte du conte d’E.T.A. Hoffmann, « L’homme au sable » ( Contes nocturnes, 1817), commenté par Freud dans « L’inquiétante étrangeté » (1919), et nous avons donc interrogé le lien de l’insomnie avec la notion freudienne de l’inquiétante étrangeté.
Rêves traumatiques et cauchemars d’exilés
Authors: Baldet Isabelle 
Published: March 2021

La difficulté à dormir, voire son impossibilité, la répétition de cauchemars horrifiques et la ténacité de terreurs nocturnes sont souvent les motifs qui conduisent les réfugiés d’un cao (centre d’accueil et d’orientation) à se présenter à « l’accueil-psy », proposé depuis trois années par des psychanalystes bénévoles. Écouter cette plainte et leur proposer de raconter ce qui hante leurs jours et leurs nuits est une façon d’entrer de plein fouet dans des existences que la vie a cruellement malmenées et de mettre à l’épreuve la théorie freudienne du rêve, du traumatisme et de la pulsion de mort.
L’analyse de l’activité en sciences de l’éducation : entre aspirations scientifiques et exigences pragmatiques
Authors: Albero Brigitte 
Published: March 2021

En clôture de ce numéro, cette contribution a pour but de discuter les positions épistémologiques des articles proposés. Elle contextualise l’approche adoptée dans certains travaux (l’analyse du cours d’action) en relation avec les principales caractéristiques de la discipline (sciences de l’éducation) et avec d’autres approches qui ont en commun l’intérêt pour l’analyse de l’activité. La première partie rapproche l’apport de ces travaux d’une caractéristique structurelle spécifique de la discipline, à savoir l’interrelation étroite entre dimensions épistémique, praxéologique et axiologique, propre à l’acquisition humaine des connaissances. Le postulat invoqué par certains auteurs d’une capacité d’autonomie également distribuée chez tous dans l’acquisition des connaissances est ensuite interrogé. Dans une deuxième partie, les travaux sont situés par rapport à l’intérêt, récent dans la discipline, pour le concept d’ « activité » et la production d’une diversité d’approches qui tendent davantage à coexister qu’à dialoguer. La question se pose alors de l’absence d’intérêt dans nombre d’études pour le rôle et la fonction toujours plus déterminants des objets techniques dans les formes actuelles de l’acquisition des connaissances. La troisième partie rapproche des travaux fondateurs dans le domaine, des cadres théoriques, des concepts et des méthodes susceptibles de constituer un corpus commun aux différentes approches de l’analyse de l’activité, référé aux caractéristiques structurelles de la discipline.
Hydroxychloroquine dosing and toxicity
Authors: Al Adel Fadwa , Shoughy Samir S. , Tabbara Khalid F. 
Published: March 2021

PURPOSE:
To assess the ocular toxicity in patients on high doses of hydroxychloroquine (HCQ) per weight, as per the latest American Academy of Ophthalmology (AAO) screening guidelines for HCQ toxicity.

METHODS:
This is a multi-center study looking at consecutive patients attending the ophthalmology clinics at a tertiary hospital and a private clinic in Saudi Arabia. A data collection sheet was used to collect patient's information regarding the dose per body weight, duration of HCQ use and any risk factors associated with the use of the medication as per the latest AAO guidelines for HCQ screening. Ancillary testing including fundus photography, automated visual field (10-2) and spectral domain ocular coherence tomography were done. Further testing with fundus auto-fluorescence and multifocal ERG were done when needed. The presence or absence of toxicity was recorded.

RESULTS:
A total of 63 patients were included in the study, 58 females and 5 males. The average patient age was 45 years (range 18–72). The mean dosage of HCQ was 3.9 mg/kg. Fourteen (22%) patients were on doses higher than 5 mg/kg. The duration of treatment ranged from 1-30 years (average 8.3). Thirty six (57%) patients were on the drug for more than 5 years. We found only one (1.58%) patient with HCQ toxic retinopathy over a mean of 8 years treatment period.

CONCLUSION:
A significant number of our patients were found to be on doses of >5 mg/kg of HCQ, which may put them at a higher risk for retinal toxicity. Low dose HCQ such as 100 mg tablets should be made available to help physicians in adjusting the dose as per the latest reported guidelines by the AAO.
Back to the future in traumatic fracture shapes of lumbar spine
Authors: Fusini Federico , Colò Gabriele , Risitano Salvatore , Massè Alessandro , Rossi Laura , Coniglio Angela , Girardo Massimo 
Published: March 2021

Introduction:
Nonosteoporotic burst vertebral fracture could commonly be treated with conservative or surgical approach. Currently, decision-making process is based on thoracolumbar (TL) AO spine severity injury score. However, some factors could affect posttraumatic kyphosis (PTK) and could be taken into account. The aim of the present study is to identify if axial and sagittal fracture shape and initial kyphosis are the risk factors for PTK.

Materials and Methods:
All consecutive patients treated between 2016 and 2017 for TL vertebral fracture with conservative treatment were retrospectively evaluated in the study. Only type A3 and A4 vertebral fractures were included in the study. Patients suffering from osteoporosis or other metabolic bone disease, aged above 60 years old were excluded from the study. Initial and 6 months X-ray from injury were analyze to evaluate local kyphosis and region of injury while initial assessment was performed with computed tomography to better identify fracture type and in some cases magnetic resonance imaging to exclude posterior ligament complex injury. Axial and sagittal view of the vertebral plate was analyzed and classified in three shapes according to fragment comminution and dislocation. Statistical analysis was performed trough STATA13 software. Student's t-test was used to evaluate the differences between initial and follow up kyphosis; odds ratio (OR) was used to evaluate the role of initial kyphosis, vertebral sagittal and axial fracture shape as a risk factor for PTK. Kruskal–Wallis test was used to assess the differences among vertebral shape fractures and final kyphosis. Fisher's exact test was used to assess the differences between fracture patterns and final kyphosis.

Results:
An initial kyphosis >10° (OR 36.75 P = 0.015), shape c vertebral plate (OR 147 P = 0.0015), and sagittal shape 3 (OR 32.25 P = 0.0025) are strongly related with PTK. Kruskal–Wallis test revealed a statistically significant difference among axial fracture shape (P < 0.0001) and sagittal fracture shape (P = 0.004) and also for initial kyphosis >10° (P < 0.0001). Fisher's exact test showed a significant difference for final kyphosis among pattern c3 and other patterns of fracture (P = 0.0001).

Conclusions:
A burst type lumbar vertebral fracture affecting a patient with initial local kyphosis >10° and comminution and displacement of vertebral plate and vertebral body is at high risk to develop a local kyphosis >20° in the follow-up if treated conservatively.
Uma Proposta Metodológica para a Atribuição da Responsabilidade sobre a Origem das VTCDs baseada na Correlação de Componentes Simétricas
Authors: Ribeiro Ferreira Adrian , De Oliveira José Carlos , Oliveira Rezende Paulo Henrique 
Published: February 2021

As Variações de Tensão de Curta Duração (VTCDs) são fenômenos responsáveis por alterações do valor eficaz das tensões de suprimento por tempos inferiores a 3 minutos. Muito embora sua duração seja relativamente pequena, as mesmas exercem grande influência no funcionamento das cargas e podem, até mesmo, interromper processos produtivos. Neste particular, as regulamentações aplicáveis ao estabelecimento dos padrões de qualidade, a nível nacional e internacional, apresentam diretrizes e limites para vários outros indicadores, todavia, quanto ao fenômeno aqui considerado, à nível de distribuição, no âmbito brasileiro, estes foram recentemente contemplados pelo PRODIST-ANEEL. Muito embora ainda em estágio incipiente, fica evidenciado que, conjuntamente com as diretrizes normativas, a questão da identificação da responsabilidade das VTCDs, visando, sobretudo, consubstanciar as análises dos processos envolvendo reclamações por consumidores e eventuais medidas corretivas, suscitam a necessidade de mecanismos para uma clara atribuição quanto a origem do fenômeno, isto é, se o evento é advindo da rede de suprimento ou do próprio consumidor. Este ponto se apresenta como cerne do presente trabalho, que apresenta uma proposta de metodologia e avalia a eficácia dos resultados para os fins ora postos.

Published: February 2021

Este artigo apresenta um algoritmo de prote¸c˜ao diferencial de barramentos baseado no conceito da potˆencia instantˆanea. Esta grandeza ´e utilizada para determinar os sinais de opera¸c˜ao e restri¸c˜ao em uma formula¸c˜ao baseada nas l´ogicas 1-de-1 e 2-de-2, comumente utilizadas em rel´es comerciais. Ainda, esta t´ecnica contempla um refor¸co harmˆonico no seu sinal de restri¸c˜ao para faltas externas. A avalia¸c˜ao do algoritmo proposto ´e feita utilizando uma subesta¸c˜ao de barra dupla com disjuntor simples (230 kV), modelado no Alternative Transients Program (ATP). Os resultados obtidos mostram que o tempo de decis˜ao do m´etodo proposto pode ser na grande maioria dos casos a metade da fun¸c˜ao tradicional, baseada em correntes, considerando inclusive diferentes instante de falta, resistˆencias de falta e tipos de falta. Tamb´em, pode ser constatado que o algoritmo oferece confiabilidade para atuar corretamente diante de faltas evolutivas. Na pr´atica, a rapidez de decis˜ao da t´ecnica apresentada permite reduzir eventuais danos por propaga¸c˜ao de curtos-circuitos, representa uma maior margem de seguran¸ca para os transformadores de corrente quando saturados e se encaixa com os requerimentos de rel´es comerciais para garantir atua¸c˜oes corretas.

Authors: Oliveira Lima Yuri , De Toledo Silva Fabiana Aparecida , Caneloi dos Santos Ricardo 
Published: February 2021

Índices de qualidade da energia elétrica relacionam-se com os níveis de tensão, corrente e frequência do sistema elétrico. Com o aumento do número de equipamentos eletroeletrônicos, muitas questões relacionadas a qualidade de energia ganham destaque, visto que a esses equipamentos são bastante sensíveis as variações de tensão. Variação de Tensão de Curta Duração (VTCD) é uma condição a ser investigada, já que a mesma pode causar sérios danos aos equipamentos. A VTCD é definida como um evento com no máximo 3 minutos, impactando de forma significativa a amplitude da tensão, divididas em: afundamento de tensão, elevação de tensão ou interrupção. Os chaveamentos de grandes blocos de carga e as faltas nos sistemas elétricos são eventos que mais contribuem para a VTCD. Para analisar os efeitos da VTCD nas redes elétricas, este artigo propõe uma forma sistemática para mapear áreas críticas em termos de VTCD. Um grande número de simulações foi executado no sistema IEEE de 14 barras disponível do PSCAD, considerando diferentes tipos de faltas em cada barra do sistema adotado. Baseado nos resultados observados, foi possível observar áreas vulneráveis, onde uma falta pode resultar em valores de tensão fora dos limites pré-estabelecidos, impactando negativamente o consumidor final.
Resveratrol (3,4ʹ,5-trihydroxy-trans-stilbene) or caffeic acid phenethyl ester supplementation prevents premature ovarian insufficiency due to chemotherapy
Authors: Ersahin Suat S. 
Published: March 2021

IntroductionThis study was planned to investigate the protective effect of resveratrol (RSV), caffeic acid phenethyl ester (CAPE), and coenzyme Q10 (CoQ10) on chemotherapy-induced premature ovarian insufficiency (POI).Material and methodsTwenty-eight female rats were divided into four groups with 7 rats in each group. The groups consisted of a vehicle-treated control group (group 1), rats treated with chemotherapy followed by intraperitoneal RSV injection (group 2) or rats treated with chemotherapy followed by CoQ10 (group 3), or rats treated with chemotherapy followed by intraperitoneal CAPE injection (group 4). Cisplatin was administered intraperitoneally once daily at doses of 2.0 mg/kg for 10 days. Rats in groups 2, 3, and 4 were given RSV (100 mg/kg, i.p.), CoQ10 (20 mg/kg, oral), and CAPE (10 mg/kg, i.p.) respectively. Five animals in the sham group underwent laparotomy for ovarian weight measurements on the first day of cisplatin injection. Animals in the treatment and control groups were sacrificed two weeks later, and their ovaries were excised for histopathological analysis. Serum levels of anti-Mullerian hormone (AMH) were also analyzed.ResultsRats in groups 2 and 4 showed vaginal smears under estrogenic effect. At the end of the second week, the total body weight and ovarian weight of the animals in group 1 increased. Significantly higher mean follicle count was detected in groups 2 and group 4 compared to group 3. The ovaries of the rats in the control group showed follicles in all stages of development. While the ovaries of the rats in the RSV or CAPE showed significantly decreased numbers of primordial follicles they showed increased numbers of early growing follicles.ConclusionsBoth RSV and CAPE administration might improve follicle survival and AMH production in rats with chemotherapy-induced POI but further research is necessary.

Masinloc, Zambales: Augustinian Recollect Mission (1607-1902)
Authors: Romanillos Emmanuel Luis A. 
Published: February 2021

Zambales carved a special niche in Augustinian Recollect mission history. Recollects evangelized Mariveles, then part of Zambales, where their protomartyr Miguel de la Madre de Dios met his death. Rodrigo de San Miguel later set up five towns. In 1607, Andrés del Espíritu Santo founded Masinloc and then proceeded to create Casborran [Alaminos], Bolinao, Balincaguin [Mabini] and Agno in Pangasinan. Blessed Francisco de Jesús resided there before his 1632 martyrdom in Nagasaki. We recall the successful defense of Masinloc in 1649 against 600 Moro pirates by the natives headed by Father Francisco de San José. Its parish priest José Aranguren became Manila archbishop in 1845. In the wake of the Revolution, the returning Agustín Pérez was welcomed by his parishioners. He restored the Catholic worship and urged Aglipayans to return to the fold. In 1902, Father Pérez left due to a conflict with its anti-friar mayor. Thus, ended its Recollect history. But the legacy of Christian faith lives on. The parish church of 1745 is a witness to the zealous Recollect evangelization and the people’s steadfast Catholic faith.
