Desafios para a cooperação nacional e internacional na psicologia latinoamericana: uma análise do sistema RedALyC, 2005-2007. A cooperação e a coautoria nas publicações científicas são preditores consistentes de qualidade e impacto, porém, têm-se apontado que a tendência às mesmas depende da área disciplinar e da região. Por meio de um estudo das publicações latinoamericanas em psicologia indexadas no Sistema Redalyc entre 2005 e 2007, obtiveram-se dados para avaliar a cooperação nacional e internacional na psicologia latinoamericana. Os resultados sugerem que é necessário consolidar redes de cooperação e modificar práticas de pesquisa e publicação conjuntas, de modo que se fortaleça a cooperação na publicação de trabalhos de pesquisa em psicologia na América Latina.

A emergência da noção de comportamento simbólico em neuropsicopatologia
Authors: Verissimo Danilo Saretta
Published: May 2017

Neste artigo, apresentamos a noção de comportamento simbólico conforme estudos em neuropsicopatologia das primeiras décadas do século passado realizados, particularmente, no seio de investigações sobre as afasias. Tomamos como eixo condutor a presença da noção em questão na primeira obra de Merleau-Ponty, "A estrutura do comportamento". Com base nas pesquisas de Gelb e Goldstein, o filósofo apropria-se da semântica do símbolo e caracteriza a corporalidade humana a partir da sua capacidade de ultrapassar o caráter imediato das situações vividas. Mostramos, ainda, que a circunscrição do comportamento simbólico esteve condicionada a mudanças teórico-metodológicas que tornaram possível a passagem de concepções localizacionistas a atitudes globalistas diante dos eventos patológicos de origem cerebral.

Published: May 2017

Trata-se de pesquisa clínica acerca da experiência de ouvir vozes, centrada na análise do funcionamento de um grupo de ouvidores de vozes em um Centro de Atenção Psicossocial (CAPS). Verificamos que o exercício de construção de narrativas sobre o ouvir vozes aplicado em um dispositivo grupal produz como efeito um aumento do engajamento dos participantes nos desafios decorrentes de seu adoecimento, auxiliando na criação de alternativas que promovam a sustentação do cotidiano. O grupo se assevera, consequentemente, como um meio profícuo de avançar, coletivamente, na elaboração de soluções singulares e de criar uma comunidade de trabalho voltada para uma experiência que se caracteriza essencialmente por não ser passível de ser compartilhada.

Published: May 2017

Nesse estudo, investigaram-se as associações entre habilidades sociais e aceitação-rejeição em estudantes universitários. Foram estudados 126 estudantes universitários do curso de Educação Física de uma instituição de ensino superior particular de uma cidade do interior do estado de São Paulo. Para fins de avaliação foi utilizado um Inventário de Habilidades Sociais (IHS) e uma Medida Sociométrica que avalia a aceitação ou rejeição do estudante por seus colegas de classe para as atividades de sair e estudar. A aceitação para ambas as situações não foi explicada por nenhuma faceta das habilidades sociais para os homens. Já nas mulheres, foi explicada somente pela medida de autoexposição a desconhecidos. Essa pesquisa elucida algumas das condutas socialmente hábeis de homens e mulheres universitários que podem ser empregadas em treinamentos em habilidades sociais para se evitar a rejeição entre pares, e maximizar a aceitação.
Cenários experimentais: efeito sobre a emoção e o comportamento pró-social
Authors: Pilati Ronaldo
Published: May 2017

Emoções antecedentes ao comportamento pró-social são influenciadas pela forma como os eventos são interpretados. Estudos têm demonstrado que a atribuição de incontrolabilidade do comportamento de alguém está associada à produção de estados afetivos de simpatia ou pena. Esta asserção teórica tem sido corroborada por meio do uso de cenários de simulação experimental. O objetivo deste estudo é avaliar o efeito que a variação dos cenários, como a proximidade social do protagonista e as normas sociais subjacentes ao cenário, possuem sobre a relação atribuição-ajuda. Foi desenvolvido um estudo com 24 cenários do qual participaram 547 estudantes universitários. Os resultados indicaram que, independentemente do cenário, a percepção de incontrolabilidade levou a emoções simpáticas (ou de compaixão) que, por sua vez, estão associadas a uma maior intenção de ajuda. Além disto, cenários que emulam normas de reciprocidade estão associados à maior intenção de ajuda
Cidadania e inserção laboral assistida: a experiência do trabalho formal de adolescentes pobres
Authors: Silva Victor Hugo da
Published: May 2017

Investiga o cotidiano de adolescentes pobres partindo do relato do processo de entrada no mercado de trabalho. Participaram 15 adolescentes, sexo masculino, estudantes do Ensino Médio, de famílias de baixa renda, com 18 meses de inserção profissional, assistidos por instituição que capacita, insere e acompanha adolescentes no mercado de trabalho formal numa capital brasileira. Os dados foram coletados através de entrevistas semiestruturadas. Os resultados, considerando que a inserção profissional é uma forma de exercício da cidadania, mostram que: a inserção assistida no mercado de trabalho formal não constitui garantia absoluta de proteção aos seus direitos; as redes sociais às quais se vinculam podem ocultar violações de direitos ao se basear em relações de clientelismo; a assimilação de valores sociais do contexto de relações do ambiente laboral pode implicar afastamento do grupo de pares. Entretanto, os adolescentes avaliaram positivamente o acompanhamento fornecido pela instituição.

Background

The potential of chemotherapy as salvage treatment after failure of neoadjuvant chemoradiotherapy for locally advanced rectal cancer (LARC) has never been explored. We conducted a single-center, retrospective analysis to address this question.

Patients and Methods

Patients with newly diagnosed LARC who were inoperable or candidates for extensive (i.e., beyond total mesorectal excision [TME]) surgery after long-course chemoradiotherapy and who received salvage chemotherapy were included. The primary objective was to estimate the proportion of patients who became suitable for TME after chemotherapy.

Results

Forty-five patients were eligible (39 candidates for extensive surgery and 6 unresectable). Previous radiotherapy was given concurrently with chemotherapy in 43 cases (median dose: 54.0 Gy). Oxaliplatin- and irinotecan-based salvage chemotherapy was administered in 40 (88.9%) and 5 (11.1%) cases, respectively. Eight patients (17.8%) became suitable for TME after chemotherapy, 10 (22.2%) ultimately underwent TME with clear margins, and 2 (4.4%) were managed with a watch and wait approach. Additionally, 13 patients had extensive surgery with curative intent. Three-year progression-free survival and 5-year overall survival in the entire population were 30.0% (95% confidence interval [CI]: 15.0–46.0) and 44.0% (95% CI: 26.0–61.0), respectively. For the curatively resected and “watch and wait” patients, these figures were 52.0% (95% CI: 27.0–73.0) and 67.0% (95% CI: 40.0–84.0), respectively.

Conclusion

Systemic chemotherapy may be an effective salvage strategy for LARC patients who fail to respond to chemoradiotherapy and are inoperable or candidates for beyond TME surgery. According to our study, one out of five patients may become resectable or be spared from an extensive surgery after systemic chemotherapy.

Published: May 2017

Purpose

Few population studies have examined patterns of systemic therapy administration in metastatic pancreatic cancer (MPC) or the predictors associated with specific treatment choices.

Patients and Methods

We assessed 4,011 consecutive MPC patients who received chemotherapy between January 2005 and December 2015 at academic, private, and community-based oncology practices subscribing to a U.S.-wide chemotherapy order entry system capturing disease, patient, provider, and treatment data. Multivariate analyses of these prospectively recorded characteristics identified significant predictors of specific therapeutic choices.

Results

Overall, 100 different regimens were used in first-line treatment of MPC. First-line gemcitabine monotherapy usage fell steadily from 72% in 2006 to 16% in 2015. This steep decline mirrored increases in first-line usage of both 5 fluorouracil, leucovorin, irinotecan and oxaliplatin (FOLFIRINOX) and gemcitabine + nab-paclitaxel. Younger male patients were more likely to receive FOLFIRINOX as first-line treatment, whereas patients treated at community practices and by oncologists with lower MPC patient volume were more likely to receive gemcitabine plus nab-paclitaxel (all p ≤ .05). Among all patients receiving first-line chemotherapy for MPC, 49% went on to receive second-line therapy and 19% received third-line therapy; administration of second- and third-line therapies increased steadily over the time course of follow-up. Younger patients and those treated by oncologists with higher MPC patient volume were more likely to receive second- and third-line therapies.

Conclusion

This population-based study provides insight into treatment patterns of MPC in the U.S. Usage patterns varied greatly according to patient and provider characteristics.

Published: May 2017

Background

Monoclonal antibodies (mAb) targeting PD-1/PD-L1 have revolutionized melanoma treatment, yet data regarding effectiveness and tolerability across age groups is limited. We sought to determine the impact of age on overall survival (OS), progression-free survival (PFS), and rates of immune-mediated toxicities in patients treated with anti–PD-1/anti-PD-L1 mAb at two academic medical centers.

Methods

We retrospectively collected data on all patients with metastatic melanoma treated with anti-PD-1/PD-L1 mAb between May 2009 and April 2015. We used Kaplan-Meier and Cox regression analyses to assess OS and PFS and identify factors associated with these outcomes. We also compared rates of autoimmune toxicity across age groups.

Results

Of 254 patients, 57 (22.4%) were <50 years old, 85 (33.5%) were age 50–64, 65 (25.6%) were age 65–74, and 47 (18.5%) were ≥75 years. Across age groups, no differences existed in median OS (age <50: 22.9 months, age 50–64: 25.3 months, age 65–74: 22.0 months, age ≥75: 24.3 months) or PFS (age <50: 4.1 months, age 50–64: 6.5 months, age 65–74: 5.4 months, age ≥75: 7.9 months). The presence of liver metastases and elevated pre-treatment lactate dehydrogenase (LDH) were associated with reduced OS. Presence of liver metastasis, pretreatment LDH, BRAF mutation, and type of melanoma correlated with PFS. Overall, 110 patients (43.3%) experienced immune-mediated toxicities; 25 (9.8%) had colitis and 26 (10.2%) had endocrine toxicity. Rates of colitis, hepatitis, and pneumonitis did not differ across age groups.

Conclusion

We demonstrated that patients could safely tolerate anti-PD1/PDL-1 mAb therapy and achieve similar outcomes regardless of their age.

Published: May 2017

Background

Distress screening is mandated by the American College of Surgeons Commission on Cancer; however, there is limited literature on its impact in actual practice. We examined the impact of a pilot distress screening program on access to psychosocial care.

Methods

Edmonton Symptom Assessment System (ESAS) screening was routinely conducted at our community-based medical oncology program. Patients who screened positive for severe distress were sent to a social worker for triage and referred to the appropriate services if indicated. We compared the proportion of patients who had ESAS completed, the proportion of patients who screened positive, and the number of patients who had social work assessment and palliative care consultation over the preimplementation (September 2015), training (October/November 2015), and postimplementation (December 2015) periods.

Results

A total of 379, 328, and 465 cancer patients were included in the preimplementation, training, and postimplementation periods, respectively. The proportion of patients who completed ESAS increased over time (83% vs. 91% vs. 96%). Among the patients who had completed ESAS, between 11% and 13% were positive for severe distress, which remained stable over the three periods. We observed a significant increase in social work referrals for psychosocial assessment (21% vs. 71% vs. 79%). There was also a trend towards an increased number of palliative care referrals (12% vs. 20% vs. 28%).

Conclusion

Our community-based cancer center implemented distress screening rapidly in a resource-limited setting, with a notable increase in symptom documentation and psychosocial referral.

Biomarkers of diverse pathophysiologic mechanisms may improve risk stratification for incident or progressive diabetic kidney disease (DKD) in persons with type 2 diabetes. To evaluate such biomarkers, we performed a nested case-control study (n=190 cases of incident DKD and 190 matched controls) and a prospective cohort study (n=1156) using banked baseline plasma samples from participants of randomized, controlled trials of early (ACCORD) and advanced (VA NEPHRON-D) DKD. We assessed the association and discrimination obtained with baseline levels of plasma TNF receptor–1 (TNFR-1), TNFR-2, and kidney injury molecule–1 (KIM-1) for the outcomes of incident DKD (ACCORD) and progressive DKD (VA-NEPHRON-D). At baseline, median concentrations of TNFR-1, TNFR-2, and KIM-1 were roughly two-fold higher in the advanced DKD population (NEPHRON-D) than in the early DKD population (ACCORD). In both cohorts, patients who reached the renal outcome had higher baseline levels than those who did not reach the outcome. Associations between doubling in TNFR-1, TNFR-2, and KIM-1 levels and risk of the renal outcomes were significant for both cohorts. Inclusion of these biomarkers in clinical models increased the area under the curve (SEM) for predicting the renal outcome from 0.68 (0.02) to 0.75 (0.02) in NEPHRON-D. Systematic review of the literature illustrated high consistency in the association between these biomarkers of inflammation and renal outcomes in DKD. In conclusion, TNFR-1, TNFR-2, and KIM-1 independently associated with higher risk of eGFR decline in persons with early or advanced DKD. Moreover, addition of these biomarkers to clinical prognostic models significantly improved discrimination for the renal outcome.

Published: May 2017

Simulation of streamflow is one of important factors in water utilization. In this paper, a linear statistical model i.e. Seasonal Autoregressive Integrated Moving Average model (SARIMA) is applied for modeling streamflow data of Astore River (1974 – 2010). On the basis of minimum Akaike Information Criteria Corrected (AICc) and Bayesian Information Criteria (BIC) values, the best model from different model structures has been identified. For testing period (2004-2010), the prediction accuracy of selected SARIMA model in comparison of auto regressive (AR) is evaluated on basis of root mean square error (RMSE), the mean absolute error (MAE) and coefficient of determination (R2 ). The results show that SARIMA performed better than AR model and can be used in streamflow forecasting at the study site.
Impact of Humoral Immune Response and Absorption Effect on Dynamics of Dengue Virus
Authors: Perera S.D. , Perera S.S.N.
Published: May 2017

Dengue infection represents a global threat causing 50-100 million infections per year and placing half of the world’s population at risk. Even though how infection is controlled and cured rather remains a mystery, antibodies are thought to play a major role in clearing the virus. In this paper, we study the dynamics of dengue virus with humoral immune response and absorption effect. The proposed model incorporates a time delay in production of antibodies. The basic reproduction number R0 is computed and a detailed stability analysis is done. It was found that the model has 3 steady states, namely, infection free equilibrium, no immune equilibrium and the endemic equilibrium. Conditions for R0 were developed for the local stability of these 3 equilibrium states. The global stability was studied using appropriate Lyapunov function and LaSalle’s invariance principle. We then established a condition for which the endemic equilibrium point is globally asymptotically stable. Also it was observed that the virus count goes to negligible levels within 7-14 days after the onset of symptoms.

This research work seeks to find out the incidence that the educative software called Interactive Physics has on the students’ academic performance. The experiment will consider students who are studying their first semester in the Agronomy School, classroom “1”, at the Natural Resources College of ESPOCH. The class will be divided in two subgroups with whom an interactive simulator program will be used and it will allow students to develop skills within the collaborative learning method of Physics, specifically, the Newton’s Laws. The hypothesis is the following: making and applying the guideline called Dynamic by using the Interactive Physics influences the first semester Agronomy students’ academic performance. The above mentioned dynamic guide was used in one of the groups in order to analyze their academic performance. The other group did not use it. Then, through the statistical Chi-Squared test and the Normalized Z-score, the existence of high correlation concerning the students’ academic performance when using the didactic guide Interactive Physics was evidenced. As a conclusion it can be said that the use of this methodology improves students’ academic performance.

The marine circulation of Cintra bay located at Dakhla Oued Eddahab area (south of Morocco 23°08’N-16°20’W) has been studied from October to November 2016 by 2D hydrodynamic model. This study aims to understand the marine circulation of this bay and its hydrodynamic functioning. Mainly governed by wind and semidiurnal M2 tides, currents are generally strong in intensity (mainly > 0.5 m.s-1 ) outside the bay. Inside the bay, their intensity are less than 0.3 m.s-1 and generally oriented to the south of the bay due to the influence of the trade winds (NE). Due sometimes to the influence of W and/or SW winds, the coastal circulation of the bay is oriented from the south to the north, impacting its northern part.

Published: May 2017

We study the transient two-dimensional flow problems related to the recharge of groundwater using an approach based on the physics of water transfer in the whole domain, including both the saturated and the unsaturated zones. Such a domain is limited by the soil surface and by the lower impervious boundary of the aquifer. The flow problem is solved using a numerical iterative procedure based on the alternate directions implicit finite differences method. To simulate the water transfer in an unsaturatedsaturated porous medium, we developed a mathematical model based on a single flow equation used for both zones. To this end, the unsaturated and saturated zones are regarded as only one continuum and the Richards equation is used for both zones. The simulated results were validated by the calculation of the mass balance, then on values obtained by an experimental model of 160 cm length and 50 cm in height. The numerical model reproduces in a satisfactory way the experimental results giving the spacetime evolution of the level of water table.

Published: May 2017

In Morocco, the quality of water gathered in dams is deteriorating considerably due to different sources of pollution. One of the consequences of this situation is the presence of nutrients , particularly phosphorus and nitrogen, in the water. This, however, indicates an advanced state of eutrophisation of waters. This phenomenon causes an imbalance in the ecosystem with an anarchic development of seaweeds and an intense consumption of oxygen at the bottom of lakes. The present study aims to present the results of the optimization of the choice of the pumping area of the waters of the BAB LOUTA dam in TAZA region, Morocco. This dam is the dam that provides the city of TAZA with drinking water. The results of physico-chemical analyses (dissolved Oxygen, Turbidity, Manganese, pH, and the temperature) were taken according to a vertical deep profile for a duration that spreads from March 2016 to March 2017.

Wavelet analysis is a relatively new technique, an enormous interest in the application of wavelets has been observed in the recent years. In this paper, we use the wavelet analysis on the upwelling index based on sea surface temperature data from 1993 to 2014 along the Moroccan Atlantic coast, mainly at Cape Cantin, Cape Ghir, Cape Juby, Dakhla and Cape Blanc. We noticed that from Jan 1993 to Oct-1998 and from Sep-2007 to Nov 20014, the upwelling in the five research latitudes increases with fluctuations. The period of Upwelling varies sensitively with the change of time scale. The value of upwelling index in the five latitudes appears similar and present an obvious period of one year in all latitudes studied. This study can be considered an important tool for time series analysis, which can help the studies concerning the upwelling variability.

In order to improve the knowledge of the functioning of tropical rainfall forests in the Congo basin ,a study on the quantification of the stocks of carbon in coarse woody debris was done in Likouala’s area, in Republic of Congo. To achieve this goal,14 squares plots of 50mx50m had installed on the whole study area, including ten plots in primary forest and four in secondary forests. The method used was to make an inventory of woody debris lying on the ground or Log and snags in the different study plots. There sults of this study revealed average stocks of 603.45kg MS.ha -1 in primary forests, 468.64 kg MS.ha-1 in secondaryforestsand392.68 kgMS.ha- 1 in agroforestry, with no significant differences between stocks in primary forests and secondary forests (P = 0.05). In addition this study revealed that carbon stocks varied from one locality to another in all the study area, as well as between the experimental plots (p = 0.005). This study helps to understand that the Chablis played a key role in the production of large woody debris.

The objective of this work is to identify the components of the knowledge to be taught relating to the concept of chemical bonding and its associated concepts in specialized reference books intended for the cycle of bachelor's and preparatory classes. The reference works analyzed were chosen in such a way that the publishing years covered a long period. Examination of these works revealed that there is a clear discrepancy in the content of instruction. The definitions of chemical bonding in reference books depend on the dates of publication of each book. In addition, the set of concepts associated with chemical bonding appears to have several definitions that are sometimes different in the background and may cause learning barriers.

Objective: The objective of this study is to identify the plant species and to characterize the vegetation of the Ouoghi forest reserve in the commune of Savè (Center-Benin). Method and results: Floristic and forest inventories were carried out through 144 relevés in according to the Braun-Blanquet method. A total of 246 plant species were identified. They belong to 178 genera and 63 families. Multivariate analyzes with the Community Analysis Package (CAP) software made it possible to individualize 3 vegetation formations comprising 8 plant groups. This is the shrub savannah with Prosopis africana and Pennisetum polystachion, the tree savannah with Hymenocardia acida and Pennisetum polystachion, the tree savannah to Vitellaria paradoxa and Pennisetum polystachion, the tree savannah to Pterocarpus erinaceus and Hyptis suaveolens, the woodland savannah with Daniellia Oliveri and Chromolaena odorata, the woodland savannah at Isoberlinia doka and Pennisetum polystachion, the woodland savannah at Daniellia oliveri and Andropogon tectorum and the tree flood savannah to Daniellia oliveri and Leersia hexandra. The floristic and structural parameters change from one group to another. Thus, the specific richness varies from 49 to 153 species and the diversity of families is between 22 and 49 with a predominance of Leguminosae. The density varies from 95 to 275 stems / ha, basal area from 2.35 to 8.44 m² / ha. Conclusion and application of results: The study evaluated the floristic diversity of the Ouoghi reserve. In addition, it indicated the need for its integral protection for its dynamics towards dry dense forest vegetation. Sustainable management of this site needs implication of local population.
A New Interpretation of Geodynamic Context and Typology of Moroccan Anti-Atlas Silver Deposits
Authors: Amina Wafik , Abderahmane Ramdani , Nouaman El Aouad , Mohamed El Ghazali
Published: May 2017

The argentiferous deposits in the Anti-Atlasic chain in Morocco are encased in the meta-sedimentary, volcanic-sedimentary and volcanic terrains of the Neoproterozoic, structured and schistosed during the Pan-African orogenesis. These deposits are associated with terminal Neoproterozoic rhyolites and granitoids. The deposits of Zgounder, Imiter and Bou Madine have similarities; Structurally are controlled and associated with faults; The source of the mineralization is generally magmatic or crustal. Precipitation of the mineralization would result from the mixing of mineralized fluids with meteoric waters or brine pools. The silver deposits in the Anti-Atlas are characterized by a number of criteria, which confirm their orogenic character. These deposits are associated with orogenic accretion events in relation to Pan-African orogenesis during the Neoproterozoic. Mineralization is syn- to post-peak metamorphism, controlled and associated faults, with veins that can have significant vertical extensions. The pressure gradients, and temperature metamorphism, indicating an orogenic environment, with metamorphic facies greenschist in general. These deposits can all be linked to an argentiferous mega-event during the Upper Neoproterozoic and thus define an argentiferous metallogenic province.

Since the end of the 19th century, cutaneous leishmaniasis (CL) has been regarded as a public health problem in our country, Morocco. The aim of this study is to describe the clinical and epidemiological profile and posttherapeutic evolution of patients with cutaneous leishmaniasis in the Ain Dfali’s health center. We carried out a study based on the use of records and the observation of patients with cutaneous leishmaniasis between January 2006 and December 2015. Also, we collected 132 cases of cutaneous leishmaniasis. The mean age of patients was 19.8 years with extremes from 6 months to 61 years. The sex ratio was 0.76 M / F. The mean duration of lesions was 1.6 months with extremes of 2 weeks to 10 months. Fall preponderance was noted (41.6%). The most frequent clinical appearance was that of a single ulcero-pulmonary nodule (61%) (71.9%) and was seated on the face (57.5%). The diagnosis was mentioned clinically and confirmed by direct parasitological examination. Glucantime® was the treatment of choice that was used intralesionally. The post-therapeutic evolution was favourable with almost a complete disappearance of lesions. This took place in a period varying from 3 to 8 weeks at the price of unsightly scars in 19 patients. Cutaneous leishmaniasis continues to pose a real public health problem in our country. The emergence of severe and resistant forms throughout the world should encourage the multiplication and strengthening of prophylactic measures.

In Biaka, theestimated values were: L = 140,7 mm, K = 0,68 year -1, Φ' = 4,13, Z = 1,52year -1, M = 0,91 year -1, F = 0,61 year -1 and E = 0,40 year -1 . Aboisso specimens have a higher growth performance index (Φ') than Biaka's and a weak longevity (tmax = 2 years) compared to Biaka (tmax = 4.41 years). Shrimps are under exploited in the locality of Biaka (E 0.5). Total mortality is higher in Aboisso than in Biaka. However, the survival rate recorded in Aboisso (S = 0.003 years) is lower than that of Biaka (S = 0.22 years). Recruitment is continuous throughout the year, with two peaks (a major peak in September and a minor peak in February) in Aboisso. As for Biaka, the presence of a normal distribution indicates that recruitment is single. These results will serve as a database for rational management of A. scabra.
Antibiotics consumption in the Eastern Region Of Libya 2012-2013
Authors: Khalifa A , Bukhatwa S , Elfakhri M
Published: May 2017

Background: Drug utilization studies conducted in Libya during the period 1991-2013, have pointed out the irrational use of antibiotics as a common practice that costs the health system more than 7.7 million Libyan Dinars / year. The aim of this study is to assess the trend of antimicrobial consumption in the Eastern region of Libya during 2012 – 2013.

Methods: Antimicrobial consumption data from the years 2012 and 2013 were obtained mainly from Benghazi office, Medical Supply Organization (MSO; the only official drug-importing body in Libya). This study is concerned with antibiotics imported only to the Eastern region of Libya, population of which represents approximately 35% of total Libyan population. The WHO, Anatomical-Therapeutic-Chemical (ATC) classification and the Defined Daily Dose (DDD) methodology were used to calculate antibiotic consumption. The total antimicrobial consumption data were calculated as DDD/1000 inhabitants/day.

Results: Total utilization of antibiotics decreased dramatically from 15.47 DDD/1000 inhabitants/day in 2012 to 4.30 DDD/1000 inhabitants/day in 2013 which in turn shows a significant decline compared to 41.72 DDD/1000 inhabitants/day during the period 1991-1993. Consumption of penicillins decreased from 19.902 DDD/1000 inhabitants/day during 1991-1993 to 1.896 DDD/1000 inhabitants/day during 2012-2013 with pattern of amoxicillin/clavulanic acid consumption equals to 3 times ampicillin consumption and is the highest compared to all penicillins. This was accompanied by a prominent increase in consumption of amphenicols and fusidic acid during 2012-2013 noting that fusidic acid consumption was the highest among all antibiotics.

Conclusion: MSO since 2011 (post 17th February 2011 revolution) lost its control on importing medicines due to receiving many drugs as donations from different international sources without acceptable level of coordination. This has been reflected on drug purchasing policy of MSO during 2013, which failed to regain the previously accepted level of DDD/1000 inhabitants/day antibiotics consumption. The decreased consumption of penicillins together with increased consumption of amphenicols and fusidic acid complies with the pattern of antibiotic resistance reported previously in Libya. Similar studies should be conducted to evaluate national drug consumption under normal conditions to be compared with regional and international data.
Barbárie e Heresia: um perspectiva religiosa para o estudo da História das Guerras - século VI
Authors: Boy Renato Viana
Published: May 2017

História das Guerras, de Procópio de Cesareia (490-562), narra as guerras promovidas pelo imperador bizantino Justiniano, visando à restauração dos antigos domínios imperiais no Mediterrâneo. Nessas narrativas, o historiador apresenta fundamentos ideológicos que justificam as ações militares do império. Entre eles, está o fato de os antigos territórios romanos estarem então sob domínio bárbaro e estes romperem com uma unidade romana. Um elemento fundamental na constituição dessa unidade estava no pertencimento da população à religião cristã, livre de práticas heréticas.Assim, a luta contra os bárbaros apresentava também um aspecto de defesa do cristianismo contra outros tipos de culto, em especial, o arianismo. A proposta aqui é analisar como Procópio articula uma aproximação entre os conceitos de barbarie e heresia na História das Guerras, justificando ascampanhas de Justiniano como o ataque de um Império cristão a populações bárbaras e heréticas.
La Imagen del Dragón en Beowulf, Historia Peredur Vab Efrawc y Völsunga Saga
Authors: Barreiro Santiago , Russo Luciana Cordo
Published: May 2017

La presencia de monstruos con forma de gusano o serpiente que descansa sobre un tesoro y se opone a algún héroe es un motivo presente en la literatura medieval. Posee diferentes configuraciones en textos como Beowulf, Völsunga Saga e Historia Peredur vab Efrawc. Nuestro análisis comprende un estudio del vocabulario específico (haciendo énfasis en la etimología y el campo semántico), la función narrativa (inserción en la estructura del relato, finalidad y motivaciones) y el carácter social y cultural de cada texto. Concluimos que, sobre un grupo de motivos literarios comunes basados en un rechazo a la acumulación, cada dragón fue construido de modo distinto en cada obra; la Völsunga Saga se enfoca en los elementos genealógicos y de parentesco, mientras que Beowulf demuestraun núcleo más aristocrático-político, y en Peredur el dragón es esencialmente parte de una trama de aventuras.
Sanctitas in Somnium: elementos oníricos da santidade segundo o Replicatio Sermonum ad Prima Conversione, de Valério do Bierzo

A Antiguidade Tardia é considerada uma época de transformações entre os mundos clássico e medieval.Dentre os diversos aspectos que podemos analisar e que a caracterizam como um período de transição entre dois períodoshistóricos, destacamos neste artigo o objeto dos sonhos, a maneira como são descritos e interpretados em uma baliza temporal específica que congrega referenciais clássicos e vislumbra elementos inéditos, que espreitam novas nuances referentes àsmudanças sócio-econômicas da Hispania. O artigo centraliza a abordagem do sonho em um documento de alcunha de Valério doBierzo, no reino hispano-visigodo, no século VII.
Raul Glaber: um historidor na Idade Média (980/985-1047)
Authors: De Almeida Néri Barros
Published: May 2017

Embora chamada Histórias, a obra de Raul Glaber pouco foiconsiderada em seu caráter historiográfico. A força de uma concepção de Idade Média como época marcada por grandes deficiências, perdas e carências lançou para segundo plano aquela que as evidências mais imediatas fazem pressupor se tratar da razão fundamental do manuscrito: a composição de texto pertencente a um gênero narrativo particular. Para alguns, a suposta “barbarização” da sociedade teria marcado o declínio dos gêneros narrativos antigos que na Idade Média deles conservariam praticamente apenas o nome. Este texto pretende discutir esses pressupostos e a relevância que pode ter para o historiador medievalista um texto de história tão fracamente difundido em seu tempo como as Histórias de Raul Glaber.
Literatura e Leituras do Milenarismo em Georges Duby (1919-1996)

Pecado, Penitência e Ordenamento Social no Romance de Melusina
Authors: Amaral Flávia Aparecida
Published: May 2017

O objetivo deste artigo é discutir como a noção do pecado é tratada em uma obra do século XIV, o Romance de Melusina ou a História dos Lusignan. A glória e poder alcançados por essa família aparecem como fruto de ações não meritórias, que fazem com que o autor esteja em uma constante tensão ao apresentar tanto a linhagem quanto sua fundadora, Melusina, na condição de pecadora/penitente. Quando discutimos essa característica da história dos Lusignan, percebemos a tensão dopróprio autor em relação à figura de Melusina e de sua condição sobrenatural. A partir da natureza da relação de Raimundo e Melusina, casal que protagoniza a história do encontro feérico, aponta-se também para uma ideia de ordenamento social presente nanarrativa.
Tipología de las Campañas Militares ocurridas en la Frontera Luso-Extremeña durante la Guerra de Sucesión Castellana a la muerte de Enrique IV (1475-1479)
Authors: Casillas Carlos Jesús Rodrígues
Published: May 2017

Tradicionalmente la Guerra de Sucesión que enfrentó a Juana e Isabel por el Trono de Castilla se ha venido estudiando desde las campañas militares que se llevaron a cabo en la franja geográfica de la zona del Duero. Sin embargo, la frontera entre Castilla y Portugal fue un espacio marcado por el signo de la violencia de forma constante durante todo el conflicto sucesorio. Por desgracia, todavía son escasos los estudios que hacen referencia a la actividad militar desarrollada en dicho marco geográfico para los años de 1475 a 1479, por lo que este estudio tratará de realizar una aproximación al análisis y relevancia estratégica de las distintas operaciones militares que se vinieron dando durante ese contexto de beligerancia generalizada entre Castilla y Portugal.
A Casa e o Patrimônio da Rainha de Portugal D. Filipa de Lencastre: um ponto de partida para o conhecimento da casa das rainhas na Idade Média
Authors: Silva Manuela Santos
Published: May 2017

Desde o momento do seu matrimónio, as rainhas de Portugalgozavam de rendas próprias que obtinham da aplicação de jurisdição sobre determinadas vilas que pertenciam ao património da coroa. Esses rendimentos sustentavam o guardaroupa da rainha e sobretudo a sua casa, isto é, o conjunto de senhoras e de oficiais que cada rainha juntava em sua volta para o seu serviço e companhia. Ao casar com a filha primogénita do duque inglês de Lancaster, João I, rei de Portugal, preocupou-se de imediato em montar uma casa à sua rainha, dando-lhe para isso meios adequados. Por mérito do rei e da rainha ou da sua administração, o seu reinado significou um período de reformas no funcionamento da casa das rainhas.
De instrumento a Víctima: miedo al Rey y Privanza en la Crónica de Pedro I del Canciller Ayala
Authors: Devia Cecilia
Published: May 2017

Se emprende aquí el estudio de un tema que se reitera en la Crónica de Pedro I del Canciller Ayala: el miedo al rey, estrechamente ligado a la función simbólica de la violencia. Sedestaca la relación entre el miedo al rey y los privados, en especial su paso de instrumento a víctima, tomando como ejemplo el caso de Juan Alfonso de Alburquerque, quien siendo al comienzo del reinado de Pedro I el principal ideólogo y brazo ejecutor de gran parte de las acciones violentas del rey, pasa a convertirse en su principal destinatario, al no ser más funcional a los deseos y necesidades del monarca.

A história em trajes de brocado. Forma, tempo e processo em Johan Huizinga e Herbert Grundmann.
Authors: Aubert Eduardo Henrik
Published: May 2017

Este artigo tem por objetivo realizar uma leitura detalhada das obras O outono da Idade Média, de Johan Huizinga, e Movimentos religiosos na Idade Média, de Herbert Grundmann, a partir de um núcleo de problemas teóricos fundamentais no panorama de crise do historismo em que elas se inserem. A opção por um tratamento conjunto dos dois livros se justifica como um meio de delimitar a diversidade das respostas dadas pela práxis historiográfica aos problemas que então se lhe colocavam.
A perspectiva filosófica do conceito de essência (quod quid est) em Jonh Duns Scot: o problema da quod quid est singular.
Authors: Carrara Maurício Alves
Published: May 2017

O conceito de essência, durante a Idade Média, não foi concebido de forma una nos mil anos da era medieval. A partir do século XIII, com a entrada da obra Metafísica de Aristóteles o conceito de essência começou a tomar contornos mais realistas. John Duns Scot (c.1226-1308) desenvolve este conceito com bases em Aristóteles e Avicena, mas se diferencia dos dois. Scot passa a entender a essência como algo próprio dos últimos indivíduos. Assim, ele faz de outro modo em relação aos seus anteriores na Idade Média. Este artigo tem por propósito apresentar esta originalidade do Doctor Subtilis em relação ao seu conceito de essência (quod quid est).
Der Heiligen Leben (Vidas de Santos): poder e espaço nas legendas de Margaretha von Antiochien e Barbara
Authors: Silva Daniele Gallindo Goncalves
Published: May 2017

No que tange ao conceito de poder, muito se afirma tendo como parâmetro as teorias desenvolvidas por Michel Foucault e Pierre Bourdieu. Ambos os autores também se aventuraram a pensar o conceito de espaço. Contudo, neste artigo pretendemos escapar desse lugar comum ao dialogar com os pensamentos de Heinrich Popitz, sociólogo alemão, e com a abordagem de estudo do espaço proposta pelo ‘Spatial turn’. Focando os dois relatos contidos na Der Heiligen Leben sobre Margaretha von Antiochien e Barbara, procuraremos, assim, compreender as construções discursivas no que diz respeito à relação entre poder e espaço.
As "Esparsas" no Cancioneiro Geral de Garcia de Resende: Forma e conteúdo
Authors: Fernandes Geraldo Augusto
Published: May 2017

As esparsas são uma das formas poéticas de que se valeram os poetas palacianos portugueses presentes no Cancioneiro Geral de Garcia de Resende, editado em 1516. Sua característica é ser monostrófica, servir ao improviso e ao desenvolvimento de máximas, exempla, ditos, caros ao homem medieval. De forma fixa, as esparsas propiciaram possibilidades variadas de gênero e de conteúdo, aliando tradição e inovação. No Cancioneiro de Resende, distinguem-se quatro espécies de conteúdos temáticos.
