Infection-Associated Peripheral Nerve Hyperexcitability
Authors: Sivadasan Ajith , Nair Aditya , Miraclin Angel , Mani Arun Mathai , Prabhakar AT , Jude Prakash John Antony , Mathew Vivek 
Published: July 2020

Background:
Peripheral nerve hyperexcitability (PNH) and neuromyotonia have been mainly attributed to antibodies against voltage-gated potassium channels (VGKC). Concurrent autoimmune disorders, malignancies, and heavy metal toxicity have also been implicated. There is scarce mention about infection as a triggering factor for PNH. There are no reports of methicillin-resistant Staphylococcus aureus (MRSA) infection being a possible precipitating factor for development of PNH.

Methods:
Case series and literature review.

Results:
Four subjects were diagnosed to have features of PNH based on clinical and electrophysiological assessment. All the subjects had concurrent evidence of cutaneous abscesses requiring surgical intervention and antibiotic therapy. The cultures in all of them revealed growth of Staphylococcus aureus with three of them being MRSA isolates. Two subjects tested positive for anti-VGKC antibodies. There was remarkable resolution in neuromyotonia after antibiotics in three subjects. One subject succumbed to fulminant MRSA septicemia.

Conclusion:
There appears to be a definitive link between staphylococcal infection (MRSA in particular) and development of PNH. The temporal evolution of PNH associated with the infection and resolution following treatment of the infection does support a causal association. The enterotoxins produced by staphylococci act as superantigens and could trigger an inflammatory cascade along with development of cross reacting antibodies against VGKC in peripheral nerves. Future studies with animal models could provide more directions in this regard.

Published: July 2020

Background: Umbilical cord care is the handling of the umbilical stump of new-born after delivery. Hygienic umbilical cord care is important for the well-being of the newborn infant. The study was to assess the knowledge, practice and techniques of umbilical cord care among mothers in Primary Health Care centre in Nwezenyi, Ebonyi State, Nigeria .
Methodology: The study was cross-sectional descriptive in design. Systematic sampling method was used to select 222 participants. Data were collected with semi-structured interviewer administered questionnaire and analyzed using Statistical Package for Social Sciences version 22.
Results: The study showed high (83.3%) awareness of umbilical cord care and low (11.7%) knowledge of proper material (chlorhexidine) for umbilical cord care, poor (8.1%) practice of the use of correct material. Factors influencing the choice of material used are cost (16.7%), availability (17.1%), convenience (10.4%), “works faster” (20.7%) and “type respondent is aware of” (35.1%).
Conclusion: High awareness of umbilical cord care management in this study did not commensurately translate to use of correct materials for its care. Thus, there was high risk of neonatal infection including neonatal tetanus. Focused health education to mothers will help improve their knowledge, practice and the use of correct material in umbilical cord care to reduce neonatal morbidity and mortality.

Authors: Daboer JC , Afolaranmi TO , Banwat ME , Tagurum YO , Gokir JD 
Published: July 2020

Background: Malaria remains the most important infectious disease in sub-Saharan Africa. Over exposure of the parasite to antimalarial medicines has precipitated the emergence of drug resistance to these medicines. The World Health Organization in 2010 issued a new policy of universal parasite-based diagnosis as a prerequisite for treatment. This study aimed at determining if Primary Health Care workers in Pankshin Local Government Area are complying with the new policy.
Methods: Using stratified sampling technique, six clinics were selected from Pankshin Local Government Area. Relevant information on all patients treated for malaria between 1st May 2015 and 30th April 2016 was extracted from clinic records. All health workers who attended to patients were interviewed while a facility inventory form was used to collect information on availability of drugs and supplies. Data generated were analyzed using Statistical Package for Social Sciences version 20.
Results: Out of 2909 patients studied, only 37.3% were tested for malaria parasites before treatment; 68.4% of whom had microscopy while 20.5% had Rapid Diagnostic Test. For those not tested 22.5% had Artemisinin Combination Therapy while 48.1% had non-Artemisinin Combination Therapy. Out of those who tested negative for malaria parasite, 8.8% and 21.6% were treated with Artemisinin Combination Therapy and non-Artemisinin Combination Therapy respectively Those who tested positive received Artemisinin Combination Therapy alone (35.5%) or in combination with other drugs (64.5%). Testing influenced the choice of drug for malaria treatment and this was statistically significant (p < 0.001).
Conclusion: Pretreatment testing for malaria and adherence to test results in Primary Health Care clinics in Pankshin are low. Concerted efforts are required for their training and supervision on the current guidelines on malaria diagnosis and treatment.

Published: July 2020

Background: Hepatitis B virus is the most serious type of viral hepatitis and can cause both acute and chronic infections. The aim of the study was to assess the knowledge of hepatitis B virus infection and its mode of transmission among women of reproductive age in Work and Study programme of Ebonyi State University Abakaliki, Nigeria
Methodology: This was a descriptive cross-sectional study. A systematic sampling technique was used to select 326 respondents. Information was obtained using a pre-tested, self-administered questionnaire. Statistical Package for Social Sciences, version 22 was used in the analysis.
Results: Majority (77.6%) of the respondents were aware of hepatitis B virus infection and the major (50%) source of information was health workers. Knowledge on method of transmission of the virus included blood transfusion, 62.3%; unprotected sexual intercourse, 54.0%; mother to child transmission, 40.5% while for prevention, screening of blood before transfusion had 62.6%; vaccination, 48.8% and use of condom, 42.6%. A minor proportion (32.5%) had been vaccinated with the Hepatitis B vaccine and only 39.6% had received the recommended three doses. The major (50%) reason for non-vaccination was ignorance. Out of 27.0% who had been screened for the virus 1.5% knew they tested positive for hepatitis B surface antigen.
Conclusions: Majority of the respondents were aware of hepatitis B virus infection. Though most of the respondents had good knowledge of the transmission of the virus, their understanding of the methods of prevention was poor. There is need for public enlightenment on the burden of hepatitis B virus infection in Nigeria and the availability and importance of the hepatitis B vaccine.

Published: July 2020

Background: Adolescence is characterized by experimentation into sexual activities. When adolescents leave home to reside in boarding secondary schools, peer pressure can result in voluntary and involuntary sexual activity even when they don't know about its immediate and long term health practices of adolescents in boarding secondary schools in a rural community, in Plateau State. effects. This survey aimed at assessing background sexuality knowledge, perception and
Methods: A cross-sectional study of 1019 secondary school students sampled using proportionate sampling technique from three rural schools in Plateau State. Data obtained from them using self-administered questionnaires, were analyzed using EPI INFO version 3.5.3 and STATA 13. Chi square test and Multiple Logistic Regression were the statistical tests used and the p-value was set at p < 0.05.
Results: Majority of the students (57.7%) had good sexuality knowledge although 89.1% of them felt confident to refuse a sexual advance. There was a significant relationship between their sex and level of confidence. A high proportion of respondents (40.5%) were sexually active and there was an association between their sex and age of onset, and whether first sexual act was voluntary or not. The odds of an adolescent being sexually active are six times as likely if aged between 19-21years; and seven times as likely, if lacking self-confidence.
Conclusion: A high proportion of the students had good sexuality knowledge and was sexually active. There is need for proper sexuality education and life skills trainings from reliable sources for school-aged adolescents.

PP4 e a Vila Expo’98
Authors: Pinto Pedro 
Published: July 2020

Em 2018 assinalam-se 20 anos da inauguração da Expo´98. A operação reconversão da frente ribeirinha oriental de Lisboa, que transformou 340 hectares de terrenos industriais e portuários em tecido urbano. A operação seria estruturada com um plano geral, cinco planos de pormenor e respetivos projetos de espaço público.
Este artigo aborda o Plano de Pormenor 4 (1994) e Projeto do Espaço Público (1996) correspondente da Zona 4 da Expo’98. Plano e projeto acolheriam durante o certame a Vila Expo´98, uma área residencial para os funcionários da exposição mundial, que após o evento seria colocada no mercado de venda livre.
Nos anos pós-Expo a implementação do plano teria um sucesso comercial assinalável. Como morfologia urbana o plano almejava um desenho urbano que proporcionasse variedade e complexidade, entendo o espaço público como coisa formal. A ideia de cidade proposta pretendia ser conciliadora: entre um modelo de cidade histórica lisboeta e a cidade moderna dos anos 50; entre as estruturas urbanas circundantes e a nova cidade projetada; entre um sistema de espaços públicos contínuo e uma conformação de edifícios em quarteirões semiabertos ou, ainda, entre operação urbanística orientada para o lucro e a incorporação de valores paisagísticos e ambientais a escala inusitada.

<div data-canvas-width="82.4750337835114"><p>The squinches isa very versatile construction type in the field of stonework. It is defined in its most elementary case as the covering of a triangular area with a conical surface, but, nevertheless, there are an infinite number of variants increasing the complexity of the layout and its execution.The studied case in this paper is the development of the layout of the "square conical vault" (actually, a cantilevered vault), in the treatise on stonework by Tomás Vicente Tosca, published in 1727. This author's work reflectsthe tradition of the local area (which comes mainly from the brilliant episode of the 15th century in Valencia), but it is also part of the pre-illustrated cultural trends of the time. The traces that appear are the result of combining ancient graphic habits with the development, to a certain extent, already scientific, of geometry and mathematics.All this leads, in the case of the "conical-square vault", to the development of a fundamentally descriptive trace, result of a mentality that is more analytical than practical, but that does not manage to emancipate itself from the old building tradition, as this study makes evident, and also the detected graphic habits.The research is also based on other examples of a documentary nature, such as the cantilevered domes of Vandelvira, Philibert de l'Orme, Gelabert, and on a built example; the squinch of the palace of the Generalitat de Valencia.</p></div><div data-canvas-width="145.94326164079826"> </div>

The economic growth and the pervasiveness of the new information technologies have configured a new landscape in which children have gained an increasing access to consumption goods and commercial messages trying to reach their attention and interest. This piece of research represents a seminal study in the field of children advertising in Latin America. It examines the characteristics of advertisements aimed to children in a sample of Chilean TV from aerial and paid platforms. Results show that pieces of advertising aimed to children in this country tend to follow similar patterns as those detected in developed countries in terms of the level of presence of advertising, most advertised products and persuasive techniques used. However,
important problems were detected in the use of those practices that facilitate children’s understanding of advertising.
Logo Selection and Modification Guidelines: an empirical international validation in Chile
Authors: Olavarrieta S. Sergio , Friedmann Roberto 
Published: July 2020

Logo selection and modification is a common marketing practice; brand managers and other marketing executives will normally face these kinds of decisions. However, logo design and modification have been largely neglected in the marketing literature. Few studies have empirically tested the effects of logo design characteristics on consumer responses (see Henderson and Cote 1998). In this paper, we set out to extend this research and guidelines to an international setting. This is thought to be particularly important, because in today’s environment, brand strategy decisions often need to take into consideration the potential of expanding and competing globally, and brand elements can be perceived quite differently. In particular, our study replicates the cited work in a developing Latin-American country (i.e., Chile), to test the cross-cultural relevance and stability of US-based logo guidelines in the context of a developing Latin-
American nation with a vibrant marketplace.

El trabajo refiere a historias escritas por trabajadores(as) chilenos(as), las que son entendidas como manifestaciones culturales de la vida en organizaciones. Para el estudio de las historias se
combina el método hermenéutico y el psicoanálisis en la capacidad que tienen para la interpretación de textos. Se analizan 39 historias de trabajadores, las que son categorizadas según distintos géneros poéticos, trágico, épico, cómico, romántico y místico. La interpretación de las historias permite conocer sobre los significados culturales subyacentes que en ellas se transmiten en el contexto de la participación de hombres y mujeres en la sociedad y organizaciones chilenas posindustriales. La interpretación de las historias también refiere a significados de sometimiento y de resistencia en la cultura organizacional. El estudio revela cómo los trabajadores a través de sus historias son protagonistas en la creación de la cultura de organizaciones.
Open Market Share Repurchases and Earnings Management
Authors: Rodríguez Arturo , Yue Heng 
Published: July 2020

In this study we examine earnings management around open market share repurchases. We examine two hypotheses: managerial opportunism and market response, both of which predict that
managers will manage earnings down prior to an open market repurchase. Using 2,939 repurchase announcements during 1980- 1998 we find evidence that managers do manage earnings down before share repurchases. We also find that the market does not identify the earnings manipulation when the repurchase is announced, and that discretionary accruals can explain a significant part of long-term positive returns following repurchases. Altogether the evidence is consistent with the managerial opportunism hypothesis. Further investigation indicates that managers with higher ownership in the firm are more likely to manage earnings down.

Este trabajo se centra en los factores relevantes para el inversionista en fondos mutuos accionarios. Específicamente se focaliza en los
flujos netos que ingresan a un fondo y su relación con factores de
desempeño, costos y otros atributos. Se utiliza la metodología de
Fama y MacBeth (1973), y se detecta fuerte sensibilidad de los
flujos a los retornos pasados, y evidencia de un comportamiento
asimétrico del inversionista frente a malos o buenos desempeños del
fondo. La variable costos de administración del fondo es
estadísticamente significativa, e importante para el inversionista.
Otros resultados indican alguna evidencia sobre la relevancia del
tamaño del fondo, y que si un fondo mutuo está relacionado a una
filial bancaria no representa una ventaja sobre otros fondos en la
industria.

El diseño vigente del sistema de pensiones considera el cobro de comisiones por la administración de las distintas cuentas que mantienen los afiliados. El depósito de cotizaciones periódicas
obligatorias en la cuenta de capitalización individual (cotización adicional) se establece como un porcentaje sobre la remuneración o renta imponible que da origen a la cotización, representando la principal fuente de ingresos de las AFP (86% en promedio para el período 2002-2012). Como resultado de tal esquema de ingresos, generalmente existen asimetrías en los retornos de los partícipes del sistema, produciendo a su vez percepciones negativas enfocadas a cambios radicales del modelo. A raíz de lo anterior, una fuente constante de discusión es el tipo de comisión
empleado y sus niveles. Al respecto, modificaciones al sistema de cobros suelen no estar exentos de tensiones. A los objetivos que busca cumplir el regulador –como suelen ser la universalidad en la cobertura y mayores grados de competencia– se suman los efectos sobre los incentivos de cotizantes y administradores. Este estudio pretende analizar el impacto de una eventual
modificación en la estructura de comisiones, considerando tanto el punto de vista de la industria –ingresos operacionales y resultados del ejercicio– como el de los afiliados –saldo
acumulado y pago de comisiones–. Adicionalmente, se entrega una propuesta de estructura de comisiones que permitiría mejorar la pensión final, sin alterar los resultados actuales de las
AFP.

Authors: Ruiz José Luis , Barrero Marcelo 
Published: July 2020

The 2010 Chilean earthquake and tsunami were among the strongest in the world history. The exogeneity of these natural disasters provides the opportunity to test stock price reactions. Using a sample of 42 firms listed in the Santiago Stock Exchange, we develop an event study methodology considering heterogeneity in volatility. Chilean stock market volatility
increased by 240% (120%) during the 5 (11) trading days after the earthquake. The results are informative about the behavior of the stock prices: returns are positive in sectors the retail, real estate, and banking sectors and negative in food, steel, and forestry. Insurance coverage decreases the impact on economic growth.

Objetivo. Describir la asignación del diagnóstico psiquiátrico realizado por psicólogos en un hospital de San Salvador. Metodología. Estudio transversal analítico de 307 consultas de salud mental entre adolescentes menores de 18 años que recibieron atención en el Hospital Nacional "Enfermera Angélica Vidal de Najarro". Se digitalizaron las consultas del período 2014-2016. Se utilizó regresión logística multinomial y pruebas de chi-cuadrado globales para evaluar la asignación diagnóstica por bloque CIE-10 de tres psicólogos. Se controló la edad y el sexo del paciente, la fecha y el servicio hospitalario que generó la consulta. Resultados. En el modelo multinomial ajustado, el chi-cuadrado global para el efecto de cada psicólogo fue estadísticamente significativo; el efecto de cada psicólogo mostró una especificidad de resultado al comparar los diagnósticos del bloque F30-F39 con los diagnósticos del bloque F40-F49, de la CIE-10, fueron los más prevalentes en la muestra. Los valores ajustados para las probabilidades de diagnóstico por bloque CIE-10 sugieren variabilidad cuantitativa en el diagnóstico según el psicólogo que lo proporciona. Conclusiones. Se identifica variación en la asignación diagnóstica por bloques CIE-10 entre los psicólogos que trabajan en un hospital urbano de segundo nivel en San Salvador. Esto deberá estudiarse con mayor profundidad.
