Learning management systems as a platform for information sharing during the COVID-19

Background:During the outbreak of the deadly respiratory coronavirus disease (COVID-19) in the 2019­2022 period, many South African institutions of higher learning adopted online learning management systems (LMS) to share information and salvage the academic project. This adoption was fraught with challenges including a lack or preparedness, resources and strategy on how to manage change. Objectives: The study examined the challenges faced while using an online LMS as an information sharing platform in academia, specifically in a rural-based university in South Africa during (COVID-19) lockdown period. In addition, the study also explored the state of readiness of the rural-based university to transition to an online LMS. Method: A quantitative research methodology was used to collect data through the administration of a survey to respondents from a rural-based university. The target population for the study was students and academic staff. Results: The study revealed that online learning management provided a collaborative knowledge and information sharing platform. This study established that LMS enabled the university to continue sharing knowledge and interact with their students, staff, and stakeholders to continue to facilitate teaching and learning. Internet connectivity, a lack of preparedness and data costs were cited as key challenges. Conclusion: This study highlighted how an online LMS was used as a collaborative and knowledge sharing platform during a global crisis. Contribution: The study contributes to information and knowledge sharing disciplines to create awareness to authorities on the importance of technology during a crisis.

Tendencias de búsqueda en Internet sobre dióxido de cloro en ocho países de Latinoamérica durante la pandemia por COVID-19 / Trends of Internet search about chlorine dioxide in eight Latin American countries during the COVID-19 pandemic

La infodemiología e infovigilancia son métodos informáticos para el análisis y seguimiento de los datos de Internet, y permiten tomar conciencia de las situaciones y crear políticas sanitarias. Este estudio se propuso analizar las tendencias de búsqueda de dióxido de cloro y términos equivalentes en Internet (chlorine dioxide solution, CDS; miracle mineral solution, MMS), en relación con la morbilidad y mortalidad por COVID-19 en ocho países de Latinoamérica. Para ello se utilizó Google Trends; el período examinado fue del 1ro de marzo al 25 de noviembre de 2020. Se calculó la media móvil por 7 días para el volumen relativo de búsqueda (VRB), la tasa de morbilidad y mortalidad. Para la asociación de las variables cuantitativas, se utilizó el coeficiente de correlación de Spearman con un nivel de significancia p < 0,05. El país con mayor interés de búsqueda fue Bolivia; el de menor interés, Brasil. El análisis del VRB con la tasa de morbilidad y mortalidad fue diferente entre países. Los picos máximos de VRB de Colombia y Chile, en abril, y de México, Ecuador y Bolivia, en julio, coincidieron con la emisión de alertas sanitarias sobre dióxido de cloro. La mayoría mostró una correlación significativa moderada y baja entre el VRB y el número de casos confirmados y muertes diarias por COVID-19. El comportamiento de las búsquedas, diferenciado entre países, podría indicar mayor interés por el tema dióxido de cloro en pandemia; lo cual se explicaría por la difusión de alertas sanitarias de organismos de salud internacionales, regionales y locales(AU)

Infodemiology and infovigilance are computer methods for the analysis and monitoring of Internet data, and allow awareness of situations and creation of health policies. This study aimed to analyze the search trends for chlorine dioxide and equivalent terms on the Internet (chlorine dioxide solution, CDS; miracle mineral solution, MMS), in relation to COVID-19 morbidity and mortality in eight Latin American countries. Google Trends was used for this purpose; the period reviewed was from March 1st to November 25th 2020. The 7-day moving average for relative search volume (VRB), morbidity and mortality rate were calculated. For the association of quantitative variables, the Spearman correlation coefficient was used with a significance level p < 0.05. The country with the highest search interest was Bolivia; the one with the least interest, Brazil. The analysis of the VRB with the morbidity and mortality rate was different between countries. The maximum VRB peaks of Colombia and Chile, in April, and of Mexico, Ecuador and Bolivia, in July, coincided with the issuance of health alerts on chlorine dioxide. Most showed a moderate and low significant correlation between VRB and the number of confirmed cases and daily deaths from COVID-19. The behavior of the searches, differentiated between countries, could indicate greater interest in the topic of chlorine dioxide during the pandemic; this would be explained by the dissemination of health alerts from international, regional and local health agencies(AU)

Evaluation of Internet websites about floaters and light flashes in patient education

PURPOSE: Flashes of light and floaters are most commonly caused by posterior vitreous separation but may be associated with sight-threatening disorders. Prevention of severe sequelae requires prompt dilated eye examination. Thus, information dissemination is crucial. This study aimed to evaluate the quality of information about floaters and light flashes available for patients on the Internet. METHODS: Cross-sectional study. In July 2005 we evaluated information available on the Internet regarding floaters and light flashes, using two search engines (MetaCrawler and MSN) and three key terms ("floaters", "dark spots eye", and "light flashes eye"). The quality of each website was evaluated using a score system. The sites were classified as academic, organizational or commercial. Readability, general quality of the website (based on: ownership, purpose, authorship, author qualification, attribution, interactivity, and currency) and quality of the specific content (definition, causes, epidemiology, diagnosis, treatment, and prognosis) were analyzed. RESULTS: Of 145 websites evaluated, 49 were included. Four sites (8.2 percent) were academic, 9 (18.4 percent) organizational, and 36 (73.4 percent) commercial. In the majority of the sites (53.0 percent) information was poor and quality was not correlated with website classification. CONCLUSIONS: Information about floaters and light flashes available on the Internet is poor.

OBJETIVOS: Fotopsias e miopsias são geralmente causadas pelo descolamento do vítreo posterior, mas podem estar associadas a doenças oculares. A prevenção de seqüelas importantes requer o exame rápido e apropriado do paciente. Portanto, o conhecimento pelo paciente é crucial. Este estudo objetivou avaliar a qualidade da informação sobre miopsias e fotopsias disponíveis para acesso dos pacientes na Internet. MÉTODOS: Estudo de corte transversal. Em julho de 2005, avaliamos as informações disponíveis na Internet sobre miopsias e fotopsias, usando duas ferramentas de busca (MSN e MetaCrawler) e três palavras-chave ("floaters", "dark spots eye", "light flashes eye"). A qualidade de cada site foi avaliada por uma escala de pontos. Os sites foram classificados como acadêmicos, organizacionais ou comerciais. Avaliamos a confiabilidade, a qualidade do site (baseada no autor, propósito, qualificação do autor, interatividade, atualizações) e qualidade do conteúdo (definição, causas, epidemiologia, diagnóstico, tratamento e prognóstico). RESULTADOS: Dos 145 sites avaliados, 49 foram incluídos no estudo. Quatro sites (8,2 por cento) foram acadêmicos, 9 (18,4 por cento) organizacionais e 36 (73,4 por cento) foram comerciais. Em sua grande maioria (53 por cento), as informações contidas nos sites foram consideradas como pobres e a qualidade não estava correlacionada com a classificação do site. CONCLUSÃO: As informações disponíveis na Internet sobre miopsias e fotopsias são insuficientes.
