Melioidosis is a major neglected tropical disease with high mortality, caused by the Gram-negative bacterium Burkholderia pseudomallei (Bp). Microbiological culture remains the gold standard for diagnosis, but a simpler and more readily available test such as an antibody assay is highly desirable. In this study, we conducted a serological survey of blood donors (n = 1,060) and adult melioidosis patients (n = 200) in northeast Thailand to measure the antibody response to Bp using the indirect hemagglutination assay (IHA). We found that 38% of healthy adults (aged 17–59 years) have seropositivity (IHA titer ≥ 1:80). The seropositivity in healthy blood donors was associated with having a declared occupation of rice farmer and with residence in a nonurban area, but not with gender or age. In the melioidosis cohort, the seropositivity rate was higher in adult patients aged between 18 and 45 years (90%, 37/41) compared with those aged ≥ 45 years (68%, 108/159, P = 0.004). The seropositivity rate was significantly higher in people with diabetes (P = 0.008). Seropositivity was associated with decreased mortality on univariable analysis (P = 0.005), but not on multivariable analysis when adjusted for age, diabetes status, preexisting renal disease, and neutrophil count. This study confirms the presence of high background antibodies in an endemic region and demonstrates the limitations of using IHA during acute melioidosis in this population.

Published: October 2018

The prevalence and intensity of soil-transmitted helminth (STH) infections in schoolchildren from Corn Islands (Nicaragua) were examined to detect mono- or poly-STH infected children, measuring different intensity levels, and to elucidate measurably increased odds of being anemic. A total of 341 stool samples provided by 2- to 15-year-old children were examined using a concentration technique and a Kato–Katz slide. Intensity of infection was expressed as eggs per gram (epg) of feces to classify light, moderate, or heavy intensity infection. A finger-prick blood sample was obtained from each student in the field. Soil-transmitted helminth prevalence was 54.3%, with Trichuris trichiura as the most prevalent species (48.9%). The combination T. trichiura/Ascaris lumbricoides (12.6%) was the most common. When T. trichiura or A. lumbricoides appeared as a single infection, light or moderate intensity infections were seen, whereas when multiple species were identified, heavy infections were present. Anemia was detected in those with any kind of STH infection (42.7%), with statistically significant differences (P = 0.004) when compared with uninfected individuals (28.2%). Polyparasite infection with one parasite species at moderate intensity and the other parasite species at light intensity or absent was found to be a significant factor for the odds of being anemic (odds ratio = 2.07). The present study reveals a high level of STH transmission requiring a deworming control program in Corn Islands and pointing to the need of improving the education and sanitary conditions of the population to avoid environmental contamination and reinfection.

Scrub typhus and Japanese spotted fever—both rickettsial diseases—are endemic and notifiable in Japan and may cause a fatal outcome without prompt treatment. Here we present the first case of a concurrent sympatric infection of both diseases with grade II evidence. A 67-year-old woman, after a single event of potential exposure to the pathogens, presented with a 12-day history of fever, pharyngeal pain, papulo-erythematous rash, and pronounced fatigue. Her erythematous rash was distributed on her trunk and extremities, palms, and soles and eventually progressed to purpura. Fever persisted until doxycycline was administered on day 12. A significant > 4-fold increase in immunoglobulin G and immunoglobulin M titers against multiple serotypes of Orientia tsutsugamushi and Rickettsia japonica were revealed by indirect immunoperoxidase assays. These clinical and serological data, even in the absence of molecular or isolation evidence, provided grade II evidence that this was a concurrent infection of sympatric scrub typhus and Japanese spotted fever.

Tropical anemia can have multiple causes, whether socioeconomic, dietary, or infectious. In the Bolivian Chaco, soil-transmitted helminthiases (STH), malaria, and Chagas disease are potential infectious causes of anemia among school-aged children (SAC). Following years of preventive chemotherapy with mebendazole, the prevalence of STH among SAC living in that area is now negligible, whereas protozoan infections are still highly prevalent (81%); Hymenolepis nana is the most frequent intestinal helminth (∼13%). We present results of hemoglobin (Hb) assessment and the association between parasitic infections and Hb levels of that SAC population. Overall, 511 SAC (girls:boys ratio 1:1, mean age 9.4 years [95% confidence interval {CI}: 9.3–9.5]) had Hb levels measured by using a point of care testing (HemoCue® Hb 301 System; HemoCue, Angelhome, Sweden). The prevalence of anemia was 23% (117/511), with mean and median Hb level = 12.2 g/dL (95% CI: 12.1–12.3; range 9.2–15.4 g/dL). By multivariate analysis, H. nana infection was associated with an increased risk of anemia (odds ratio 2.9, 95% CI: 1.5–5.7, P = 0.002). Two samples (0.5%) were positive for Trypanosoma cruzi and none for Plasmodium spp. by polymerase chain reaction of the 439 children tested. Anemia is still a concern among SAC living in the Bolivian Chaco. Our findings call for a greater attention to fecal–oral emerging pathogens, such as H. nana, and highlight the importance of water, sanitation, and hygiene improvements for disadvantaged population such as those living in the Bolivian Chaco.

Enteric fever is a systemic bacterial infection in humans that is endemic in Cambodia and for which antibiotic resistance is increasingly reported. To guide public health programs, this qualitative study sought to explore community perceptions on transmission and treatment. Participant observation was carried out in hospital settings, pharmacies, and at a community level in Phnom Penh. In-depth interviews 39 and one focus group discussion were carried out with blood culture–confirmed enteric fever patients and purposively selected key informants. Informants were theoretically sampled based on initial themes identified using abductive analysis. Nvivo 11 was used for thematic coding. An urgent need to address health literacy concerning the transmission of enteric fever was identified, as lay informants did not link the disease and its symptoms to bacterial contamination of foods and drinks but rather to foods considered “bad” following humoral illness interpretations. As a result, lay informants considered recurrence of enteric fever preventable with appropriate dietary restrictions and Khmer traditional medicines. This study also reveals pluralistic health-care–seeking behavior. For initial and mild symptoms, patients preferred home treatment or traditional healing practices; limited household finances delayed treatment seeking. When symptoms persisted, patients first visited drug outlets or private practitioners, where they received a mix of nonessential medicines and one or more antibiotics often without prescription or confirmation of diagnosis. Inappropriate use of antibiotics was common and was related to diagnostic uncertainty and limited finances, factors which should be addressed during future efforts to improve the uptake of appropriate diagnostics and treatment of enteric fever.
Pirzad’s Diasporic Transnational Subjects in “A Day Before Easter”
Authors: Yaghoobi Claudia
Published: October 2018

In “A Day Before Easter,” Zoya Pirzad highlights the fact that despite the forced dislocation and the necessarily hybrid existence of Armenians in Iran, Armenians have by and large adopted a monolithic notion of who they are. Bringing the characters’ diasporic consciousness to light, this article argues that Iranian Armenian identity reflects the cultural clashes that are an inevitable consequence of such an interweaving of cultures and histories across religious and ethnic divides. However, the lived reality for Iranian Armenians has changed over time. Taking into account the Armenians’ forced relocation and their citizenship in Iran, this article considers Pirzad’s new generation as diasporic transnational subjects.

El propósito principal de esta investigación fue evaluar la relación entre la espiritualidad, la búsqueda de sensaciones y las conductas sexuales de alto riesgo, con la intención de corroborar o descartar la espiritualidad como variable moderadora en esta relación. Para poner a prueba el modelo de moderación, se utilizó una muestra de 563 adultos puertorriqueños mayores de 21 años de edad, seleccionados por disponibilidad. La edad promedio de los participantes fue de 33,83. El diseño utilizado fue no experimental de tipo transversal correlacional. Según nuestros resultados, se encontró una relación baja, negativa y estadísticamente significativa entre la espiritualidad y las conductas sexuales de alto riesgo. A pesar de esto, se evidenció que, en este estudio, la espiritualidad no ejerce suficiente impacto como para disminuir la relación que existe entre la búsqueda de sensaciones y las conductas sexuales de alto riesgo.

Published: October 2018

Se examinó el efecto del ingreso económico de las personas al descuento del valor relativo de recompensas demoradas y probables. Se expuso a 40 adultos jóvenes de ingreso económico alto y 40 de ingreso económico bajo a una tarea de descuento temporal o probabilístico con recompensas de diferente magnitud, utilizando un procedimiento de ajuste de la magnitud. Se obtuvieron las tasas de descuento y áreas bajo la curva por grupo de ingreso económico. Globalmente, se encontró que los participantes con ingreso alto descontaron menos las recompensas demoradas que los participantes con ingreso bajo en todas las magnitudes de la recompensa demorada. En descuento probabilístico, cuando la magnitud de la recompensa probable fue relativamente pequeña, los participantes con ingreso alto descontaron menos su valor; a medida que aumentó la magnitud de la recompensa probable, no hubo diferencias en el descuento de la recompensa entre grupos de participantes.
Two Surgeon Approach for Complex Spine Surgery: Rationale, Outcome, Expectations, and the Case for Payment Reform
Authors: Bauer Jennifer M. , Yanamadala Vijay , Shah Suken A. , Sethi Rajiv K.
Published: October 2018

There is an increased trend in complex spine deformity cases toward a two attending surgeon approach, but the practice has not become widely accepted by payers. Multiple studies have shown that spine surgery complications increase with the duration of case, estimated blood loss, and use of transfusions, as well as in certain high-risk populations or those requiring three-column osteotomies. Dual-surgeon cases have been shown to decrease estimated blood loss, transfusion rate, surgical times, and therefore complication rates. Although this practice comes at an uncertain price to medical training and short-term costs, the patient's quality of care should be prioritized by institutions and payers to include dual-surgeon coverage for these high-risk cases. Because we enter an era where the value of spine care and demonstrating cost-effectiveness is essential, dual surgeon attending approaches can enhance these tenets.

Published: October 2018

The American Academy of Orthopaedic Surgeons has developed the Appropriate Use Criteria (AUC) for the Management of Developmental Dysplasia of the Hip in Infants up to Six Months of Age: Intended for Use by General Pediatricians and Referring Physicians. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The Management of Developmental Dysplasia of the Hip in Infants up to Six Months of Age: Intended for Use by General Pediatricians and Referring Physicians AUC clinical patient scenarios were derived from indications typical of patients presenting with developmental dysplasia of the hip in clinical practice. The 24 patient scenarios and four treatments were developed by the Writing Panel, a group of clinicians who are specialists in this AUC topic. Next, a separate multidisciplinary, Voting Panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a 9-point scale to designate a treatment as Appropriate (median rating, 7 to 9), May be Appropriate (median rating, 4 to 6), or Rarely Appropriate (median rating, 1 to 3).

Authors: Caballero David R. , Rosado Nayibe
Published: October 2018

A troublesome pronunciation issue for Spanish EFL learners is the past -ed ending of regular verbs. Neuro linguistic Programming (NLP) is a perspective integrating neurology, language and programming which are key for processing information and for responding to learners’ styles with the potential to help EFL teachers address this pronunciation issue. This paper reports a study conducted in two subsequent terms with 43 students at a university language institute: two groups taught using standard pronunciation techniques and two using NLP techniques preceded by oral tasks in which they were encouraged to pronounce regular verbs in the past. Data collected included students self-recorded pronunciation tasks, a survey to elicit students’ motivation and satisfaction and a teacher’s log with insights about students’ attitude and response to the strategy. Analysis of the data showed that after the first implementation, the NLP group improved their pronunciation a 30%, the standard one improved a 10%. During the second implementation, the NLP group showed an improvement of 23.7% pronunciation accuracy in task 1 and a 24.6% in task two compared to the standard group. The findings suggest that teacher’s use of NLP techniques into their classroom instruction have a positive impact on students’ pronunciation of the past ending of regular verbs.

The aims of study were to evaluate the effect of sowing time in summer season on agronomic characteristics of sweet corn grown in summer season in Northwest Paraná, Brazil. The experiments were conducted in 2011, and 2012, in both years, the sowing was carried out on ST1: 09/05; ST2: 09/19; ST3: 10/03; ST4: 10/17, and ST5: 10/31. The experimental design was a randomized block design in a 5 × 2 factorial scheme, consisting of sowing time and two corn hybrids, with four replicates. The evaluated variables were plant height, leaf area index and yield of commercial ears, in which the effects of sowing times were studied through regression analysis, and effects of hybrids and agricultural years were studied by F-test. Sowing times promoted reductions in phenology of hybrids, but did not provide variations in degree-days accumulation by hybrids. The maximum leaf area index (3.82) was estimated for 10/04. In year 2011, the maximum plant height (2.17 m) and yield (13.0 Mg ha-1) were estimated for 10/06, and 10/03, respectively. While, in year 2012, the maximum height (2.22 m) and yield (12.85 Mg ha-1) were obtained on 10/09 and 10/11, respectively. The hybrid RB6324 showed greater yield potential, independent of year.

Published: October 2018

Tomato (Solanum lycopersicum L.) is a crop whose cultivation is of great importance in economic and social aspects. However, the development of efficient and low-cost technologies is essential for the growth of agricultural activity in the region. Among the most studied technologies, the production of quality seedlings in organic substrates is highlighted. In this context, the objective was to evaluate the development of tomato seedlings produced with organic substrates, using the decomposed stem of babassu palm and goat manure, using the multidimensional technique with the help of canonical functions associated with growth analysis. The treatments consisted of 25%, 50% and 75% sand aggregates, 25% to 50% sand addition, 25% to 50% sand and commercial substrate, established in a completely randomized design with 28 treatments and four replications in a 7 × 4 factorial scheme, the first factor consisting of seven substrates and the second of four evaluation periods (7, 14, 21, 28 days after emergence). Were analyzed shoot length and main root length; dry mass of the aerial part and of the root system and leaf area. These variables were analyzed through multidimensional analysis with the help of canonical functions and growth analysis. In general, the substrates consisting of goat manure and sand were superior to the substrates consisting of the decomposed palm tree stem and the commercial substrate. The alternative substrate formed by the mixture of goat manure, in the proportion of 25% of sterilized sand + 75% goat manure, constitutes the best option for the production of tomato seedlings.

Published: October 2018

The present study aimed to characterize the growth of Handroanthus heptaphyllus seedlings in a nursery, planted under different container volumes and doses of controlled release fertilizer (CRF), and to verify whether the responses obtained in the nursery are confirmed in the field. For the production of seedlings in the nursery, three volumes of container (180 and 280 cm3 polypropylene tubes and 500 cm3 polyethylene bags) and four CRF doses (0, 4, 8, and 12 g L-1 of substrate) were used. At 180 d after emergence, height (H), stem diameter (SD), H:SD ratio, shoot dry weight, root dry weight, total dry weight, Dickson Quality Index, leaf area, root length, and fluorescence of chlorophyll a were evaluated. The same treatments were evaluated again in the field 540 d after planting, and the survival, increase in H and SD, as well as shoot dry weight, leaf area, chlorophyll fluorescence, and chlorophyll index (a, b and total) were measured. In the nursery, seedlings of H. heptaphyllus responded positively to the volume of the container, as well as the base fertilization using CRF. However, when planted in the field, the plants that received the best nutritional conditions in the nursery showed good performance and was favored in the field. Thus, in the production of quality seedlings, the use of containers of the type polypropylene tubes with 180 cm3, and basic fertilization with 12 g L-1 of CRF conditions that enable growth of H. heptaphyllus in the field are recommended.

The present research had the objective to use the factor analysis in the evaluation of the competitive capacity of three native species from the Carajás National Forest in competition with different plant densities of the Urochloa brizantha grass. The experiment was conducted in a greenhouse and consisted in planting pots with the native species Bauhinia longipedicellata, Mimosa acutistipula and Solanum crinitum in competition with the exotic grass Urochloa brizantha. The exotic grass was established at densities ranging from 1 to 5 plants per pot, composing a 3 × 5 factorial arrangement with four replications that were delineated completely at random. Data were submitted to factor analysis for further analysis of variance and Tukey’s test at a 0.05 level of significance with the extracted factors. The effects of U. brizantha densities were evaluated by regression analysis. Out of the four extracted factors, three could be interpreted and were defined as vegetative growth index, infestation density index and physiological quality index. The Solanum crinitum species was slightly greater than the others in terms of vegetative growth rate and physiological quality. Generally speaking, native species maintain their vegetative growth in competitive conditions with up to two Urochloa brizantha plants; above that, the vegetative growth index tends to zero, while the infestation density index becomes positive.

Currently, the management practices employed in Brazilian sugarcane plantations have contribute to soil physical degradation and, few studies considering the effect of cover crop associated with conservationist soil tillage systems to control or even reverse this process. Therefore, with the aim to assess the impact of cover crop and tillage systems on the least limiting water range (LLWR) and the S index in two soils of different textures used for sugarcane production, a fieldwork was carried out in two sugarcane plantations in the state of São Paulo, Brazil. The experimental design is a split-plot with four repetitions. The main factor consisted of soil cover vegetation: cover crop and fallow, and the second factor, the tillage system: minimum tillage and conventional tillage. The data of this study demonstrated that clayey and medium-textured soil are sensitive to the management systems used. The use of cover crop promoted an increase of LLWR (average incremental rate of 105% for clayey and 100% for medium-textured soil) and S index (average incremental rate of 16% for clayey and 10% for medium-textured soil). The maintenance of soil under fallow represented restrictive conditions for the growth/development of the plants due to the degradation of the soil structure. In addition, conservation management systems, such as minimum tillage, resulted in better soil physical quality when associated with cover crop. Finally, the clayey and medium-textured soil, show good S index during the first cycle of sugarcane cultivation.

Published: October 2018

Rice, the major crop sustaining approximately half the world population, has been extensively reported to be sensitive to saline conditions. However, the genetic and physiological understanding related to long-term salinity stress remains unclear so far. The aim of this study was to evaluate the mechanisms of salinity tolerance in a salinity-tolerant variety of rice, Nona Bokra, and to detect the chromosomal regions responsible for it. We utilized chromosome segment substitution lines (CSSLs) carrying segments from Nona Bokra in the genetic background of a salt-sensitive variety Koshihikari by investigating the plant growth, grain productivity, and ion contents in plants subjected to long-term salinity stress. Comparison of plant growth and grain yield of CSSLs grown under long-term saline conditions suggests that the salinity tolerance of Nona Bokra involves the improvement of plant dry matter, panicle number, and percentage of ripened grains. Nona Bokra has the chromosomal regions for the improvement of the panicle number on chromosome 2 and the percentage of ripened grains on chromosome 6 or 10 under salinity conditions. It was suggested that these chromosomal regions were related to Na+ and Cl- exclusion. Low Na+ and Cl- contents in whole plant at full heading stage would be vital for improving the yield under long-term saline conditions.

Published: October 2018

The avocado (Persea americana), an edible fruit, is one of the main agricultural products in many tropical regions. Avocado fruit is rich in fat, and commercialized for fresh consumption and industrially processed leaving seed as a major residue. Avocado seed from the industry is worthy of attention for certain industrial applications and feasibility. Transforming avocado seed lipids into ecologically friendly or sustainable materials suitable for the cosmetic industry is promising from the perspective of green and environmental protection. The oil contents and fatty acid compositions of the seeds of 16 avocado accessions collected from southern China were investigated, revealing significant differences among most of the accessions. Seventeen fatty acids were identified and quantified by gas chromatography-mass spectrometry in the seeds of all 16 avocado accessions. Linoleic (40.14%), palmitic (23.54%), and oleic acids (16.23%) were the major fatty acids in the seeds, and the total contents of unsaturated fatty acids in the seeds were all higher than those of saturated fatty acids. The biochemical properties of the avocado seed oils relevant to their application in industrial practice were examined [e.g., the acid (3.74 mg KOH/g oil), iodine (124.09 g I2/100 g oil), peroxide (49.83 meq H2O2), and saponification (167.98 mg KOH/g oil) values]. Furthermore, the bar soap containing avocado seed oil was made, and its physicochemical properties (pH and foamability) were evaluated.
The analysis of conditions for testing mileage of military vehicles
Authors: Luty Witold , Mieten Marcin
Published: October 2018

The study discusses the issue of determining the conditions for testing the mileage of a vehicle. Lifetime tests are the crucial element of qualification tests. This type of research verifies the resistance of vehicles and elements of their on-board equipment to vibrations and shocks resulting from the interaction of uneven surface during the movement. Certain test conditions can be straightforwardly determined and verified e.g. weather conditions or a type of the road/surface. The problem appears when the tests are to be conducted in field conditions (off-road). At the set driving speed, the level and frequency structure of dynamic loads of elements of a vehicle drive system depend mainly on a surface profile and its viscoelastic conditions. Either the profile or the characteristics of ground foundations change over the time depending on various factors. The paper attempts to assess the interaction of a ground surface of selected field roads on a vehicle. The result of direct measurement of the vertical acceleration captured on a drive axle and on a vehicle’s frame above the axle was addressed. The measurement results were analyzed within the context of possible planning of vehicle test requirements with the application of the method of testing mileage under the field conditions.

A Frequency Domain-Based Sensitivity Study of a Submarine Manoeuvring Model
Authors: Giles Siobhan , Valentinis Francis
Published: October 2018

A frequency domain-based analysis of a submarine maneuvering model has been completed and used to study the effects of parameter uncertainty. The maneuvering model of the BB1-X submarine has been analyzed for the purpose of understanding the consequences of reduced input fidelity. Inputs were varied individually and ranked based on the resulting deviation from the original model. The model was also reduced to include fewer degrees of freedom or dynamic effects and compared with the original fully detailed model. The intention of this study is to determine which data are most crucial to the accurate maneuvering simulation of a submarine. Depending on the application of such a model, certain accuracies may be sacrificed to reduce resource requirements and save cost. The results of this study give some guidance as to which types of parametric data need to be the most detailed. Although the results will not give exact sensitivities for all submarine maneuvering models, it will give an indication of which areas should be focused on.

1. Introduction

Producing a maneuvering model of a submarine must always be a balance between desired model fidelity and available resource and time. Depending on the purpose of a particular model, fidelity may be sacrificed in certain areas in the interests of reducing computational time or data input requirements. Before making this reduction, however, it is important to understand how various simplifications will affect the overall dynamic characteristics. If this is well understood, the process of creating models that are fit for purpose can be streamlined.

The parametric data for a maneuvering model are often produced through experimental work or computational fluid dynamics (CFD) simulations. A certain amount of force and moment data can provide sufficient information to calculate a set of hydrodynamic coefficients which are used to populate a maneuvering model. The higher the data requirements, the longer these processes take. When reducing the extent of parametric data required, it is desirable to reduce detail in a manner which has minimal effect on the maneuvering model, and therefore, it is important to know which of the hydrodynamic coefficients are the most significant. For submarines, there is very little documented information about this in the open literature. An effort to describe the significance of some coefficients was first attempted by Ray et al. (2010). Ray provides an analysis of the hydrodynamic coefficients and their effect on a longitudinal zigzag maneuver. The analysis, however, focuses on eight coefficients and vertical plane motion only. The analysis in this report is significantly more comprehensive.
Basilar Artery Occlusion: Clinical Management and Therapy
Authors: Sparaco Marco
Published: October 2018

Basilar artery occlusion is a potentially life-threatening subset of the larger category of posterior circulation strokes, carrying > 80% fatality rate without treatment. This condition accounts for about 1% to 4% of all ischemic strokes and is generally related to local atherothrombosis or cardioembolism.Diagnosis can be challenging because presenting symptoms are often non focal, such as headache, dizziness, and vertigo. The onset of the symptomatology can be abrupt without preceding events, abrupt with prodromal symptoms, or progressive and stuttering. Finally, the severity of clinical presentation may range from isolated cranial nerve palsies to tetraplegia, locked-in state, or coma.If basilar artery occlusion is readily recognized and confirmed with the aid of neuroimaging, intravenous thrombolysis or endovascular treatment can be undertaken immediately in order to recanalize the occluded artery and thus reduce mortality and improve outcome.
LES ENJEUX INTERSECTIONNELS DE LA DEMANDE DE SERVICES DE SANTÉ MENTALE AU CANADA
Authors: Gaborean Florina , Negura Lilian , Moreau Nicolas
Published: October 2018

Dans cet article, nous présentons, selon le cadre théorique féministe intersectionnel, une étude visant à mieux comprendre les dynamiques identitaires qui influencent la demande de services de santé mentale des jeunes femmes francophones vivant en situation minoritaire ainsi que les effets croisés de celles-ci sur les facteurs déclencheurs de la dépression, la perception des symptômes et le parcours thérapeutique. Notre analyse révèle que l’imbrication de plusieurs catégories d’inégalité complexifie l’accès aux services de santé mentale des jeunes femmes dépressives en situation minoritaire tout en favorisant l’émergence de stratégies de lutte et de résistance. Le croisement des catégories identitaires de genre, d’âge et de langue parlée produit des effets compensatoires sur la demande de services de santé mentale. Alors que l’image sociale positive de la jeunesse les fait hésiter dans la demande de services, celle liée à l’identité féminine légitime, la dépression et les faiblesses qui pourraient en découler. Les femmes mettent en oeuvre des stratégies pour pallier les inégalités d’accès aux services de santé mentale en français et trouver les services qu’elles considèrent appropriés pour leur problème spécifique. Au lieu de favoriser la discrimination ou la marginalisation, cette imbrication d’appartenances identitaires multiples permet le renforcement du pouvoir d’agir des jeunes femmes francophones.
MODÈLES D’INTERVENTION MÉDICAL ET ENVIRONNEMENTAL AUPRÈS DES PERSONNES MANIFESTANT UN TROUBLE GRAVE DU COMPORTEMENT, QUELLES SONT LES DIVERGENCES?
Authors: Longtin Véronique , Paquet Maxime
Published: October 2018

L’inclusion des personnes présentant une déficience intellectuelle ou un trouble du spectre de l’autisme et manifestant des troubles graves du comportement demeure un défi. Les pratiques soutenues par les ressources d’hébergement de la communauté se rapportent parfois encore à des traditions institutionnelles. Cet article vise à comparer les sujets d’études récentes associées aux modèles d’intervention médical et environnemental pour en déceler des divergences. Une analyse thématique inductive des titres et résumés de 113 articles a permis de les classifier sous 12 catégories émergentes et ainsi, de proposer des orientations de recherche futures basées sur des lacunes de couverture des sujets recensés.

Published: October 2018

Le test de Zulliger est un test projectif à administration collective basé sur la technique des taches d’encre. L’objectif de cet article est de discuter de la pertinence de l’utilisation du test de Zulliger au Québec par le biais d’une recension de la littérature. Dix-sept études comparatives ou transculturelles sont présentées et donnent du support à cette discussion. Les réflexions effectuées suggèrent que le test de Zulliger est un instrument économique, rapide, simple, profond et polyvalent. Cela tend à justifier la pertinence de son utilisation au Québec ainsi que la pertinence des études sur le sujet.
L’INFLUENCE DES ÉMOTIONS INTÉGRALES POSITIVES SUR LE RAISONNEMENT DÉDUCTIF ET INDUCTIF
Authors: Gosselin Jérémie , Blanchette Isabelle
Published: October 2018

Nous avons évalué la façon dont des participants raisonnent sur un contenu positif lié à leur historique affectif. Deux groupes (parent; non parent) effectuaient des tâches de déduction et d’induction dont les contenus étaient neutre, émotif-général et émotif-lié à la parentalité. Les participants évaluaient le niveau d’émotivité des contenus. Le groupe parent avait une performance équivalente pour la déduction au groupe non parent sur le contenu émotif-lié à la parentalité, malgré un niveau d’émotivité plus élevé. Les résultats appuient partiellement la conclusion que le raisonnement est influencé différemment selon que les émotions soient liées ou non aux expériences personnelles.
La réception de Vatican II à travers les lettres circulaires des supérieures générales de la Congrégation de Notre-Dame de Montréal : 1959-1970
Authors: Laperle Dominique
Published: October 2018

Ce texte désire faire comprendre le poids des lettres circulaires des supérieures générales comme médiation de la réception du concile Vatican II. La lecture et l’interprétation du concile à travers ce type d’intercession témoignent de la singularité du processus pour chaque communauté apostolique féminine qui possède un charisme et une spiritualité qui lui est propre. De la phase préparatoire à la période conciliaire, de l’application du décret Perfectae caritatis en passant par l’adoption des nouvelles constitutions, les lettres circulaires attestent des questionnements qui tiraillent les religieuses durant la période d’adaptation, des réflexions spirituelles qui les accompagnent et aussi des solutions particulières qu’elles adopteront.
Nueva teoría sobre la depresión: un equilibrio del ánimo entre el sistema nervioso y el inmunológico, con regulación de la serotonina-quinurenina y el eje hipotálamo-hipófiso-suprarrenal

La hipótesis sobre las causas de la depresión basada en la acción de la serotonina y del sistema inmunológico, propone que ciertos tipos de estrés distorsionan la relación entre la actividad del sistema inmunitario innato y la del sistema nervioso central.El estrés causado por una infección o el estrés psicológico excesivo activan receptores de tipo toll, como el TLR-4, el factor de transcripción NF-kB, el inflamasoma NLRP3, así como la secreción de interleucina 1 beta (IL-1β) e interleucina 6 (IL-6); esto causa, en primer lugar, los síntomas generales de enfermedad que aparecen con cualquier infección, pero también los síntomas característicos de la depresión como disforia y anhedonia.Las evidencias indican que, si el estímulo persiste o se repite en las siguientes 24 horas, se activa la enzima indolamina 2,3-dioxigenasa (IDO) de la vía metabólica de la quinurenina, lo cual incrementa la síntesis del ácido quinolínico y reduce la síntesis de serotonina. El ácido quinolínico activa los receptores de N-metil-D-aspartato (NMDA) en el sistema nervioso central y estimula la secreción de, entre otras, las interleucinas IL-6 e 1L-1β, las cuales promueven la hiperactividad del eje hipotálamohipófiso-suprarrenal y refuerzan la desviación del metabolismo del triptófano hacia la producción de ácido quinolínico, así como de las interleucinas de la inmunidad innata, con lo cual se reduce más la síntesis de serotonina y se consolida el proceso depresivo.Este proceso puede ser iniciado por las interleucinas estimuladas por una infección, así como por algunas vacunas o por un estrés psicológico excesivo que active el eje hipotálamo-hipófiso-suprarrenal simultáneamente con la respuesta inmunológica innata, con lo que se provocaría un proceso de inflamación estéril en el sistema nervioso central.
