Methotrexate impaired in-vivo matured mouse oocyte quality and the possible mechanisms
Authors: Tian Ning , Lv Dan-yu , Yu Ji , Ma Wan-yun
Published: December 2019

Background: Methotrexate (MTX) is an antifolate agent which is widely used in clinic for treating malignancies, rheumatoid arthritis and ectopic pregnancy. As reported, MTX has side effects on gastrointestinal system, nervous system and reproductive system, while its potential damages on oocyte quality are still unclear. It is known that oocyte quality is essential for healthy conception and the forthcoming embryo development. Thus, this work studied the effects of MTX on the oocyte quality. Results: We established MTX model mice by single treatment with 5 mg/Kg MTX. Both morphological and molecular biology studies were performed to assess the in-vivo matured oocytes quality and to analyze the related mechanisms. The in-vivo matured oocytes from MTX-treated mice had poor in-vitro fertilization ability, and the resulting embryo formation rates and blastocyst quality were lower than the control group. We found that the in-vivo matured MTX-treated mouse oocytes displayed abnormal transcript expressions for genes of key enzymes in the folate cycles. MTX increased the rate of abnormal chromosome alignment and affected the regulation of chromosome separation via disrupting the spindle morphology and reducing the mRNA expressions of MAD2 and Sgo1. MTX reduced the DNA methylation levels in the in-vivo matured oocytes, and further studies showed that MTX altered the expressions of DNMT1 and DNMT 3b, and may also affect the levels of the methyl donor and its metabolite. Conclusions: MTX impaired the in-vivo matured mouse oocyte quality by disturbing folate metabolism and affecting chromosome stability and methylation modification.

Published: December 2019

Background: Prolonging working careers is a key policy goal in Europe, but reaching this goal is complex. Occupational health services are in the best position to contribute towards prolonging working careers, through preventing illnesses that cause work disability and early pensions. Impacting on the trajectory between illness and work disability requires continuity of care, enabled through identifying those at risk and their follow-up. We aimed to determine whether a combined educational and electronic reminder system could improve the recording of patient primary healthcare visits and follow-up of patients at risk of work disability or with work related illnesses in occupational health care, and through this, to impact on sickness absence rates. Methods: This study is a pragmatic cluster randomized controlled trial using medical record data. An occupational primary healthcare provider’s units in Finland were randomized into an intervention group consisting of both education and electronic reminders, and a control group with usual care using minimization methods. Data on patient visits were extracted from routine patient registers collected by Pihlajalinna Työterveys from 2015 to 2017. Process indicators were collected from the electronic system. Data were cleaned and analysed intention-to-treat using ANCOVA. Results: There was no significant difference between intervention and control sites in terms of sickness absences of different duration. Process indicators suggested that there was a change in physicians’ practice following the educational component of the intervention. Conclusion: Education with an electronic reminder can change physicians’ practice, but longer term follow-up is needed to determine whether this impacts on patients’ sickness absences.

Published: December 2019

Background Rapid control of cholera outbreaks is a significant challenge in overpopulated urban areas. During late-2017, Kinshasa, the capital of the Democratic Republic of the Congo, experienced an increase in cholera cases that showed potential to spread throughout the city. A novel targeted water and hygiene response strategy was implemented to quickly stem the outbreak. Methods We describe the first implementation of the cluster grid response strategy carried out in the community during the cholera outbreak in Kinshasa, in which water and hygiene response activities targeted cholera case clusters. Interventions, which focused on emergency water supply, household water treatment and safe storage, home disinfection and hygiene promotion, were organized using a grid approach. We also performed a preliminary community trial study to assess the temporal pattern of the outbreak, before and after response interventions were implemented. Cholera surveillance databases from the Ministry of Health were analyzed to assess the spatiotemporal dynamics of the outbreak using epidemic curves and cartography. Results From January 2017 to November 2018, a total of 1,712 suspected cholera cases were reported in Kinshasa. During this period, the health zones most affected included Binza Météo, Limeté, Kokolo, Kintambo and Kingabwa. Following implementation of the response strategy, the weekly cholera case numbers in Binza Météo, Kintambo and Limeté decreased by an average of 57% in two weeks and 86% in four weeks. The total weekly case numbers throughout Kinshasa Province dropped by 71% at four weeks after the outbreak peak. Conclusion During the 2017-2018 period, Kinshasa experienced a sharp increase in cholera cases that showed potential to rapidly spread throughout the city. To contain the outbreak, water and hygiene response interventions targeted case households, nearby neighbors and public areas in case clusters using a grid approach. Following implementation of the response, the outbreak in Kinshasa was quickly brought under control. A similar approach may be useful to quickly interrupt cholera transmission in other urban settings.
LEFT VENTRICULAR HYPERTROPHY AND LEFT ATRIAL DILATATION AS MARKERS OF MALIGNANT ARRHYTHMIAS DEVELOPMENT
Authors: Shushkovska Yuliia , Afanasiuk Oksana
Published: December 2019

One of the pressing problems of modern cardiology is the study of the etiological and risk factors for sudden cardiac death (SCD). Arrhythmias, which in most cases correlate with signs of myocardial hypertrophy, are important for its occurrence. The most common cause of left ventricular hypertrophy (LVH) is hypertension. However, an equally important trigger mechanism for malignant arrhythmias is coronary heart disease (CHD). It is known that LVH is considered as an independent risk factor for cardiovascular complications. Methods. The study design included an assessment of the effect of cardiac remodelling, the degree of LVH, and the degree of dilatation of left atrium (LA) on the development of malignant disorders of rhythm and conduction of the heart (DRCH). 78 patients with II degree of hypertension were examined. Patients were divided into two groups depending on the presence of CHD. In each group, there were malignant rhythm and conduction disorders. The control group consisted of 20 healthy people. Results and discussion. The stages of LVH were equally represented in both groups, but the concentric LVH, the initial degree of LVH, and the dilatation of LA predominated. In patients with malignant DRCH, a moderate degree of LVH predominated. Significantly, more likely malignant DRCH occurred in the second group and presented with high-grade ventricular extrasystoles, prolonged QT interval, and sinus node weakness syndrome.
EFFECTIVENESS OF CORRECTION OF DISCUSSION OF CARBOHYDRATE METABOLISM IN RATS WITH CRANIOCEREBRAL INJURY
Authors: Semenenko Sviatoslav , Semenenko Andrii
Published: December 2019

The development and introduction into practice of emergency neurology of new drugs capable of influencing secondary neuronal damage in patients with traumatic brain injury (TBI) has made a significant impact on the recovery of such patients. Aim of the work was to evaluate the magnitude of cerebroprotective action of amantadine sulfate in terms of impaired carbohydrate metabolism of the brain against the background of experimental TBI. Materials and methods. The experimental model of severe TBI was caused by the action of a carbon dioxide flow under pressure, which was created using a gas balloon of pneumatic gun. The therapeutic effect of amantadine sulfate on TBI model was evaluated with a 5 mg/kg dose. The pseudo-operated animals and control group received 0.9 % NaCl solution at a dose of 2 ml/kg with IV administration. Results. The obtained results confirm the formation of a hypo-energetic state in the brain cells of rats on the background of TBI, which is probably a consequence of the suppression of the processes of oxidative phosphorylation and its conjugation with tissue respiration. TBI is accompanied by activation of anaerobic glycolysis and inhibition of aerobic glucose oxidation, proving that there is an imbalance between the levels of lactate and pyruvate intermediates. 8-day infusion of rats with traumatic brain injury of amantadine sulfate, inhibited anaerobic glycolysis hyperactivation, stimulated tissue respiration processes, reduced signs of lactic acidosis and development of secondary alteration of brain cells by non-oxidized products. Conclusions. In the course of the experiment, it was found that the treatment of rats, with TBI model, with 0.9 % NaCl solution did not significantly contribute to the restoration of impaired energy metabolism (p<0.05) and did not reduce the manifestation of metabolic acidosis in the damaged brain (p<0.05). The use of amantadine sulphate in TBI rats significantly corrects carbohydrate metabolism disorders than 0.9 % NaCl solution and contributes to the reduction of metabolic acidosis in the damaged brain (p<0.05).
THE INFLUENCE OF RATS-MOTHERS FOOD RATION WITH NUTRIENT DEFICIENCY ON THE STRUCTURAL-FUNCTIONAL STATE OF THE LIVER OF THEIR TWO MONTHS OFFSPRING
Authors: Kuznetsova Milena
Published: December 2019

The aim of this study was to determine the influence of rats-mothers food ration with nutrient deficiency on the morphology and functional status of the liver of their two months offspring. Materials and methods. The experiments were performed on the offspring of WAG population rats, which was prenatal under nutritional deficiency. The offspring of rats (26 specimens) were divided into two groups, 50 % of the rats constituted the control group (i.e., their mothers received the vivarium baseline diet), the other 13 animals were in the 2nd (main) group. The young rats were removed from the experiment two months after birth by decapitation. Morpho-functional condition of the liver of the offspring rats treated with pregnancy deficiency of fat and carbohydrate diet was evaluated according to the results of immunohistochemical study of markers of liver vascular endothelium damage - endothelial synthase of nitric oxide (eNOS) and inducible nitric oxide synthase (iNOS) and biochemical study of liver tissue homogenates (studied fractional composition of lipids and organ glycogen). Results. It was found that the nutritional deficiency of rats-mothers had a significant effect on the structural and functional state of the liver of their bi-monthly offspring, which was manifested by a decrease in the level of endothelial synthase expression, which indicated a high degree of damage to the liver endothelium. Biochemical study of liver homogenates revealed signs of impaired secretion and reuptake of lipids, which were manifested by an increase in CL, TG and EFAs accumulation, as well as a decrease in liver PL and glycogen, which indicated the presence of pronounced disorders of carbohydrate and lipid metabolism. Conclusions. The obtained data allow us to establish the negative nature of the effect of deficiency of fats and carbohydrates in the diet of rats-mothers on the structural and functional state of the liver of their bi-monthly offspring. This condition was accompanied, both by signs of liver vascular endothelial damage and metabolic disorders, this all suggests that the identified disorders may be a risk factor for fatty hepatosis as well as liver cirrhosis in the future.
Factors affecting the liquidity of commercial banks in India: a longitudinal analysis
Authors: Bhati Shyam , De Zoysa Anura , Jitaree Wisuttorn
Published: December 2019

This paper examines the long-term effect of various regulatory, bank-specific and macroeconomic factors on the determination of liquidity in Indian banks. For this purpose, the study uses a random effect panel data regression model and tests it with data on Indian banks for 21 years, covering the period from 1996 to 2016. The model considers the effect of regulatory factors, cash reserve ratio, and statutory liquidity, and incorporates four different liquidity ratios specific to the Indian banking scenario. The results of the analysis show contrasting relationships between the independent variables and the dependent variables measured by four liquidity ratios.It is interesting to note that Indian banks rely more on asset-based liquidity and less on liability-based liquidity. More specifically, the most important liquidity ratio of L1 (liquid assets to total assets ratio) showed a significant relationship with macroeconomic variables of discount rates, call rates, foreign exchange reserve, exchange rate with US dollar, consumer price index and gross domestic product. L1 also showed a significant relationship with bank-specific variables of capital to total assets and bank size. However, the regulatory factors of cash reserve ratio and profitability determined by return on equity (ROE) and non-performing assets were not found to have any effect on liquidity of Indian banks.
Idiopathic Aplastic Anemia in Children and Adults: Diagnosis, Treatments, and Management - A Review
Authors: Alqahtany Fatmah S.
Published: December 2019

Aplastic Anemia (AA) is also known as idiopathic aplastic anemia (IAA) and the production
of new blood cells ceases in AA, which leads to an abnormal hematological syndrome such as pancytopenia
and suppression of hypo-cellular bone marrow. The pathophysiology of AA in most cases is
immune-mediated and is stimulated by type 1 cytotoxic T cells. Reliable early diagnostic tests of IAA
are not yet available, therefore most of the cases are identified in advanced stages. Recently, abnormal
immune response and hematopoietic cell deficiencies are defined genetically, such as in target cells of
telomere repair gene mutations and by the dysregulation of T-cell activation pathways. Importantly,
anti-thymocyte globulins and cyclosporine-associated immunosuppression are successful treatments
for restoring blood cell production in most of the cases, however, clonal hematologic diseases remain
challenging. In the current review, we have discussed the common practices in the treatment, pathophysiology,
diagnosis, and management of AA.
A Localization Scheme for Underwater Acoustic Wireless Sensor Networks using AoA
Authors: Toky Archana , Singh Rishi P. , Das Sanjoy
Published: December 2019

Background:

Underwater Acoustic Sensor Networks (UWASNs) have been proposed for the hard oceanographic application where human efforts are not possible. In UWASNs localization is a challenging task due to unavailability of Global Positioning System (GPS), high propagation delay and the dynamic mobility of the sensor nodes due to ocean dynamics.

Objective:

To address the issues related to the localization of the sensors for the network deployed under water. This paper presents a localization scheme specially designed for UWASNs.

Methods:

In this paper, we propose a localization scheme using Angle-of-Arrival (AoA) technique
for UWASNs. The proposed localization scheme is divided into Angle estimation phase, Projection
Phase and Localization phase. The angle estimation phase estimations the angle of the signal arriving
at the sensors. The projection phase converts the 3-Dimensional localization problem in equivalent
2-Dimensional by projecting the sensor nodes to a virtual projection plane. In the localization
phase, the position of the sensor nodes is estimated based on the Angle-of-Arrival and distance
from neighboring nodes information.

Results:

The simulation result shows that the proposed scheme provides a high localization ratio and Localization coverage with less energy consumption.

Conclusion:

A distributed range-based localization scheme for UWASNs using AoA technique is presented. The localization scheme projects the sensor nodes to a virtual plane and calculates the angle of signals initiated by the reference nodes. The scheme provides a great success in node localization and network coverage.

A exigência do exaurimento da justiça desportiva: inconstitucionalidade ou mitigação do princípio da inafastabilidade da jurisdição?
Authors: Lemos Edson , Anjos Rafael Maas dos
Published: December 2019

A exigência do exaurimento da justiça desportiva configura afronta ao princípio da inafastabilidade da jurisdição? A resposta a esse questionamento é o foco do presente estudo. No meio jurídico, desde há muito, verifica-se o ajuizamento de demandas judiciais que possuem por objeto conflitos na seara da justiça desportiva. Para o conhecimento do conflito na via judicial e o recebimento de eventual ação, é necessário passar pelo exame de uma questão preliminar: verificar se o litígio já se esgotou na seara desportiva ou se restou superado o prazo legal para seu exame. Nesse contexto, conforme se verá, a exigência do esgotamento de determinada quaestio na justiça desportiva configura a mitigação do princípio da inafastabilidade da jurisdição, e não a sua inconstitucionalidade. Buscar-se-á mapear os fundamentos constitucionais respectivos, dando-se destaque para o direito desportivo, além de analisar o direito de ação, sua origem, importância e relação com o princípio do acesso à justiça. Discorrer-se-á acerca do contencioso desportivo, a fim de encontrar subsídios capazes de esclarecer que a disposição do art. 217, § 1º, da Constituição Federal não fere o comando contido no art. 5º, XXXV, também da Carta Magna, podendo ambos os dispositivos constitucionais conviverem em harmonia.
Development and Evaluation of an HIV-Testing Intervention for Primary Care: Protocol for a Mixed Methods Study
Authors: Apers Hanne , Vuylsteke Bea , Loos Jasna , Smekens Tom , Deblonde Jessika , Van Beckhoven Dominique , Nöstlinger Christiana
Published: December 2019

Background

Late diagnosis of HIV fosters HIV transmission and may lead to hidden HIV epidemics. In Belgium, mathematical modeling indicates a high prevalence of undiagnosed HIV infections among men who have sex with men of non-Belgian origin and among sub-Saharan African migrants. Promotion of HIV testing facilitates early diagnosis, but diagnostic opportunities are missed in primary care.

Objective

The intervention study aims to enhance provider-initiated HIV testing by GPs. This protocol presents the conceptual development, implementation, and evaluation of an HIV-testing intervention for Flemish general practitioners (GPs).

Methods

A mixed methods evaluation design is used. Guided by a simplified intervention mapping approach, an evidence-based intervention was developed in collaboration, guided by an interdisciplinary advisory board. The intervention consisted of an evidence-based tool (ie, “HIV-testing advice for primary care”) to support GPs in provider-initiated HIV testing. A modified stepped-wedge design compare two different intervention levels: (1) online dissemination of the HIV-testing advice and (2) dissemination with additional group-level training. Both conditions were compared against a control condition with no intervention. The effect of the intervention was measured using Poisson regression for national surveillance data. The primary outcome was the number of HIV diagnoses made by GPs. Secondary outcomes were HIV diagnoses among groups at risk for undiagnosed HIV, distribution of new diagnoses by CD4 cell count, number of HIV tests prescribed by GPs, and rate of new diagnoses by tests. To evaluate the intervention’s implementation, the GPs’ fidelity to the intervention and the intervention’s feasibility and acceptability by GPs were assessed through (web-based) surveys and in-depth telephone interviews.

Results

The study was funded in 2016 and ethically approved in January 2017. The implementation of the intervention started in January 2017 and ended in December 2018. Data was completed in October 2019 and was the starting point for the ongoing data analysis. The results are expected to be published in the second half of 2020.

Conclusions

Results of the intervention study will provide useful information on the intervention’s effectiveness among Flemish GPs and can inform further development of official testing guidelines. Limitations of this real-life intervention approach are potential spill-over effects, delay in access to surveillance data, and little detailed information on HIV-testing practices among GPs.

El presente artículo analiza el vínculo entre Internet –fuente abundante de información– y el apego partidista, a partir de la evaluación de tres encuestas. Los autores encontraron que efectivamente los elementos se relacionan; sin embargo, ese vínculo está mediado por la edad, lo que relega a Internet a ser más un medio que un factor. Siendo así, y tomando en cuenta un enfoque psicológico del voto, se puede asumir que los ciudadanos están relativamente poco informados y que el apego partidista determina su conducta electoral.

El modelo territorial del Estado en España y sus problemas actuales
Authors: Aragón Reyes Manuel
Published: December 2019

Después de revisar el tratamiento que la doctrina española ha otorgado al modelo territorial del Estado Español (en especial las aportaciones de Juan José Solazábal), en el artículo se analiza, desde la doble perspectiva del derecho constitucional y la política constitucional, la situación actual del Estado autonómico. Se afirma la necesidad de aclarar y resolver de manera definitiva el modelo territorial español al tiempo que preservar su actual extensión territorial, para lo cual el autor expone las razones que llevan a excluir como opciones viables la confederación, el pacto con la corona y el derecho de autodeterminación. Como alternativa, el autor propone el Estado autonómico, modelo original, aún inacabado, que no sería igual al federal (con el cual carece de sentido sostener una distinción radical) ni al regional. El Estado autonómico permitiría una solución al problema territorial español, pues su flexibilidad y otras características admiten en mejor manera cierto grado de asimetría territorial y "una equilibrada integración entre dicha asimetría y la necesaria unidad estatal". En el artículo se analizan rigurosamente tanto las cuestiones teóricas como el procedimiento de reforma constitucional que podría llevar a la adopción plena del Estado autonómico en España.

Este trabalho descreve a primeira ocorrência de um granito peraluminoso na região de Porto Alegre, denominado Granito São Geraldo. Neste estudo foram realizadas análises petrográficas (microscopia óptica e eletrônica) e de química mineral (microssonda eletrônica) em lâminas delgadas oriundas de testemunhos de sondagem. O granito apresenta textura equigranular hipidiomórfica média e composição que varia de sieno a monzogranítica. Sua mineralogia é constituída por K-feldspato (37-48 %), quartzo (17-33 %), plagioclásio (23-28 %), muscovita + biotita (7-11 %) e, subordinadamente (< 1 %), granada, zircão, monazita, apatita, ilmenita e magnetita. A biotita, de origem primária, apresenta teores de elementos maiores (e.g. Al, Fe e Mg) compatível com as de granitos peraluminosos. A muscovita em geral é magmática, com composição similar a dos granitos fortemente peraluminosos (e.g. teores de Al, Fe, Mg e Ti). Os teores de Or do K-feldspato (ortoclásio) variam entre 86-97 %. O plagioclásio é  predominantemente oligoclásico, subordinadamente apresentando composição albítica. Teores elevados de espessartina da granada (26-32 %) sugerem uma origem magmática. A apatita (fluorapatita) apresenta teores de F entre 3,0-4,5 %. O caráter peraluminoso deste granito o difere de todos os granitos descritos na região de Porto Alegre. Sua composição é similar a dos granitos com duas micas que compõem a Suíte Cordilheira (Batólito Pelotas), a qual engloba a maioria dos granitos peraluminosos tipo-S, sintranscorrentes a zonas de cisalhamento transcorrentes dúcteis encontradas no domínio oriental do Cinturão Dom Feliciano.

The aim of this paper is to present a comprehensive approach to analyse and
interpret power loss in ferromagnetic materials with particular attention
devoted to excess power loss. Experimental results obtained with an Epstein
frame and toroidal core made of electrical steel are presented in the paper,
including quasistatic and dynamic hysteresis loops. According to the time
waveforms of the measured magnetic field and magnetic flux density, an
instantaneous power loss is calculated for the quasistatic and dynamic case.
Moreover, the instantaneous power loss due to eddy current is calculated, as
well as the instantaneous excess power loss and excess magnetic field. This
excess magnetic field is compared to the excess magnetic field calculated by
Bertotti?s model. Analysis and discussion of the results obtained is given
in the paper.
Estimation of parameters of Nadarajah-Haghighi extension of the exponential distribution using perfect and imperfect ranked set sample
Authors: Minic Marija
Published: December 2019

The ranked set sampling (RSS) is a cost-effective method of sampling that can be used in a wide range of statistical problems. In this paper, the shape and the scale parameters of Nadarajah-Haghighi extension of the exponential distribution are estimated based on a simple random sample (SRS) and RSS. Three cases are considered: 1) the scale parameter is known; 2) the shape parameter is known; 3) both shape and scale parameters are unknown. Observations are done when the ranking mechanism in the ranked set sample is perfect and when it is not. Method of moments, the maximum likelihood method, and a modification of the maximum likelihood method are used. The obtained estimators are compared in terms of their biases and mean square errors (MSE). The results revealed that estimators based on RSS tend to show better properties (smaller bias and MSE) relative to their SRS counterparts, regardless of the quality of the ranking.

Diálogos intertextuais de Clarice Lispector: o caso de “A Bela e a Fera” e as duas pontas da existência
Authors: Guaranha Denise Landi Corrales , Guaranha Manoel Francisco
Published: December 2019

Este artigo desenvolve uma análise intertextual do conto “A Bela e a Fera ou a ferida grande demais” (1977), de Clarice Lispector (1920-1977), com a finalidade de destacar, para além do diálogo com o conto de fadas explicitado no título, a presença de outras narrativas dessa categoria como Cinderela e A Bela Adormecida; e de narrativas mais antigas ainda: O Nascimento de Eros (Platão), Eros e Psique (Apuleio) e o mito de Narciso. A hipótese que o trabalho sustenta é a de que a intertextualidade do conto em questão remete-nos à especial circunstância em que Clarice produziu a narrativa: o agravamento de sua doença e a proximidade de sua morte, fatos que fazem do conto uma espécie de balanço existencial conciso da escritora que agrega, de modo mais evidente, à tradicional perspectiva existencial de sua escrita, a dimensão social que também emerge em A Hora da Estrela (1977).

Este artigo aborda a experiência do insólito na obra de Clarice Lispector a partir do estudo de textos curtos, publicados como crônicas. Nesses textos, o contato com a primariedade viva dos seres e das coisas constitui-se como uma experiência transformadora que produz um descortínio que abala as relações eu-outro. A reflexão se fundamenta na obra da autora, baseando-se em categorias que se oferecem ao leitor na própria obra. No caso de Lispector, o procedimento analítico segue paralelo à consideração de que sua obra constitui um paradoxal sistema de ideias que desestrutura os sistemas binários que pautam o senso comum e a vida ordinária.
Metaficcionalidade em Um sopro de vida de Clarice Lispector
Authors: Torres Luana Uchoa
Published: December 2019

Este estudo discute sobre as estratégias metaficcionais do romance Um Sopro de Vida (pulsações) publicado postumamente em 1978, porém escrito no período de 1974-1977, pela escritora Clarice Lispector. Apresentamos e refletimos sobre alguns aspectos comuns às narrativas metaficcionais, tais como: autorreflexividade ou autorreferencialidade; mise en abyme; a relação do papel do leitor e do autor; mímese do processo; e a relação ficção e realidade. Para tanto, a discussão se fundamentou principalmente nas teorias de Linda Hutcheon (1984) e Lucien Dällenbach (1977). Convocamos também, a fim de ampliar o debate, outros autores, tais como Patricia Waugh (1995), Amaryll Chanady (1987) e Laurent Lepaludier (2002).
El intento suicida en zonas rurales como un desafío a los modelos explicativos vigentes: discusión de una serie de casos
Authors: Troya Carlos , Tufiño Andrea , Herrera Diego , Tulcanaz Karina
Published: December 2019

Introducción: Existen diversos modelos explicativos de suicidio que enfatizan factores de riesgo como la predisposición genética o la presencia de enfermedades de salud mental en la explicación etiológica de la intención suicida. El modelo de Grito de desesperanza/huida sería hasta el momento una versión que recoge de mejor manera las variables de la ruralidad. Se expone además un tercer modelo explicativo que se acerque al fenómeno de la intención suicida desde una visión integradora y comprensiva mediante el re-enmarque.

Objetivo: Aplicar a una misma serie de casos de intención suicida de zonas rurales en Ecuador los aspectos relevantes de los distintos modelos de explicación del suicidio y discriminar las diferencias que cada modelo presenta a fin de desarrollar herramientas de salud mental que puedan ser aplicadas.

Metodología: La investigación tuvo un primer componente cuantitativo descriptivo en el cual se aplicó un cuestionario a las historias clínicas que tuvieron diagnósticos médicos relacionados con intención suicida. Posteriormente se administró una entrevista semiestructurada a los participantes que accedieron a hacerlo. Finalmente se aplicó los diferentes modelos expuestos a la serie de casos.

Resultados: El cuestionario se aplicó a un total de 35 historias clínicas de 35 personas (n=35). El 63% (n = 22) fueron del sexo femenino, con respecto a la composición etaria cerca del 60% (n = 21) eran menores de 18 años. Una tercera parte (n = 11) de los participantes correspondieron en el estado civil “No solteros”. Todas las personas que fueron atendidas tuvieron fácil acceso al uso de agroquímicos; en el 91% de los casos en estudio el detonante fue una discusión familiar con sus padres o sus cónyuges.

Conclusiones: Se necesitan modelos de comprensión de la conducta o intención suicida que contengan las variables propias de las zonas rurales. Los modelos actuales permiten comprender la problemática de manera parcial y aún con los sesgos de la enfermedad mental como el factor más relevante. Lo cual no siempre será acertado en zonas rurales.

Abstract:

Studying the problems of women in various fields, especially marriage, always faces its own challenges. The lack of wife's rights in marriage gets some contradictions from a gender perspective. Did not rule out the possibility of connection with the wife's right to refuse reconciliation. This paper synergizes Islamic and gender perspectives on the issue of wife's right to refuse reconciliation. Efforts are being made to identify the shifts related to the classical fiqh formulation into a more egalitarian formulation according to the guidance of modern times. In addition, the next effort is to identify a new business of reasoning from the abstract domain to concrete rules. There are two steps that can be done, namely by analyzing the problem using the theory of equality and gender justice and the theory of maslahah from the perspective of several competent figures in their fields. From this, this paper confirms the similarity of perception between the aims of Islamic teachings (maqasid ash-shariâ€™ah) and gender equality and human rights, that is the right for anyone to consider everything that will be done as long as it brings benefit.

This study illustrates the paradigm of students at the Islamic boarding school Darussalam towards the target age of marriage. It is interesting to study when the target age is significantly analyzed in the perspective of female students. This is because, in general, marriages that occur among female students are known as arranged marriages. However, this paper explores the opinions of each female santri in determining the ideal marriage age limit for their perspective. Previously, it was reviewed in advance regarding the age regulation of maturity according to classical fiqh and the rules of legislation, in this case Law No. 1 of 1974 and compilation of Islamic Law (KHI). The final analysis is to analyze the results of a survey of about 30 female students of the Darussalam boarding school. Then proceed with classifying the age of marriage in four classifications, namely the age of marriage in an ideal level, sufficient, alert, and alert. The findings of this paper provide a clear picture that women's rights in determining the age of marriage are strongly influenced by their physical and mental maturity. Therefore, indirectly invalidated at least the age of 16 years for women regulated in the Act does not pay attention to the wishes of women themselves.
