Información y desarrollo en El Salvador : notas preliminares

Analiza el uso que se le da al creciente flujo de información y tecnología informática en El Salvador en aras del desarrollo, recorriendo los diferentes ámbitos tales como centros formales, organismos del Estado, instituciones privadas, etc. Expone los ejemplos de análisis sobre el tema desarrollados por el CIID, Banco Mundial y CEPAL/CLADES. Sostiene que se está ampliando la brecha entre los informados y no informados, y plantea una serie de medidas para reducir esta brecha y aprovechar las facilidades de información para democratizar y desarrollar mejor al país

Health information-seeking among Latino newcomers - an exploratory study

ntroduction. This exploratory study examines health information-seeking practices among Latin American newcomers to a small city in the United States. The framework locates these practices within social networks, the local institutional context and the use and non-use of information technologies. <br><b>Method.</b> Semistructured interviews were conducted in Spanish with seven immigrant workers. Interviews elicited incidents of both purposive seeking and accidental encountering of health information. <br><b>Analysis.</b> Data were coded for reference to social networks, strengths of social networks, and perceptions and uses of institutions, organizations, and technologies, treating the information incident as unit of analysis. <br><b>Results.</b> Information seeking is often assisted by both social networks and key institutions, yet the quality of the information transmitted through social networks is apt to be uneven, and newcomers are unable to obtain an adequate overview of local health care for improved decision-making. Of particular interest is the finding that the local information environment has evolved significantly in response to growing demand for Spanish-language and low-income services. <br><b>Conclusion.</b> It is particularly important for information behaviour researchers to examine the dynamic interactions among study populations and their information environments over time

Investigación del comportamiento informacional a través del análisis de redes sociales

The field of information behaviour research is dominated by a constructivist vision focused on the individual as a generator of knowledge. Recently, a group of researchers have increased the criticism of this approach and advocate a social turn. From this point of view, methods such as discourse analysis are used to try to learn from the language of users how they generate and share knowledge in the social context. Other methods that could contribute to a better understanding of this aspect include social network analysis. The article describes how this method has been applied to the study of information behaviour, shows a practical application and discusses the professional and methodological implications

Reasons for poor follow-up of diabetic retinopathy patients after screening in Tanzania: a cross-sectional study

Diabetes is an emerging public health problem in sub-Saharan Africa. Diabetic retinopathy is the commonest microvascular complication of diabetes and is a leading cause of blindness, mainly in adults of working age. Follow-up is crucial to the effective management of diabetic retinopathy, however, follow-up rates are often poor in sub-Saharan Africa. The aim of this study was to assess the proportion of patients not presenting for follow-up and the reasons for poor follow-up of diabetic patients after screening for retinopathy in Kilimanjaro Region of Tanzania

Study Questionnaire. The interview was conducted in Kiswahili by a native speaker. The structured questionnaire used was pilot tested on 10 patients at Kilimanjaro Christian Medical Centre (KCMC) prior to its use in order to ensure adequate understanding. The answers were recorded in Kiswahili and then translated into English. (DOCX 84 kb

Analysis of extracellular RNA in cerebrospinal fluid

We examined the extracellular vesicle (EV) and RNA composition of pooled normal cerebrospinal fluid (CSF) samples and CSF from five major neurological disorders: Alzheimer’s disease (AD), Parkinson’s disease (PD), low-grade glioma (LGG), glioblastoma multiforme (GBM), and subarachnoid haemorrhage (SAH), representing neurodegenerative disease, cancer, and severe acute brain injury. We evaluated: (I) size and quantity of EVs by nanoparticle tracking analysis (NTA) and vesicle flow cytometry (VFC), (II) RNA yield and purity using four RNA isolation kits, (III) replication of RNA yields within and between laboratories, and (IV) composition of total and EV RNAs by reverse transcription–quantitative polymerase chain reaction (RT-qPCR) and RNA sequencing (RNASeq). The CSF contained ~106 EVs/μL by NTA and VFC. Brain tumour and SAH CSF contained more EVs and RNA relative to normal, AD, and PD. RT-qPCR and RNASeq identified disease-related populations of microRNAs and messenger RNAs (mRNAs) relative to normal CSF, in both total and EV fractions. This work presents relevant measures selected to inform the design of subsequent replicative CSF studies. The range of neurological diseases highlights variations in total and EV RNA content due to disease or collection site, revealing critical considerations guiding the selection of appropriate approaches and controls for CSF studies
