Employees Perceptions of Job Insecurity and Performance: A Qualitative Approach.

The purpose of this article is to understand the experience of workers' perceptions of job insecurity and its relation to performance. To this end, we conducted semi-structured interviews with 38 workers in the retail, services, education, financial, construction, and pharmaceutical industries in Chile. Using content analysis based on workers' accounts of their own experience, we identified two main categories: (a) the experience of job insecurity viewed in relation to the context of the COVID-19 pandemic and emotional aspects of job insecurity, and (b) the relation between job insecurity and performance. The possibility of job loss expresses itself in experiences and emotions that are related to the performance of workers in different ways. These findings are discussed in terms of stress theory and the motivation to preserve jobs.

Digital Transformation for More Equitable and Sustainable Public Health in the Age of Digital Interdependence.

This article describes 8 guiding principles for the digital transformation of the health sector and identifies their relationship with the COVID-19 pandemic, as well as highlights their importance to countries undergoing digital transformation processes. In the Region of the Americas, among other gaps, 30% of people do not have access to the Internet, which is why it is mandatory to develop policies and actions to deliver public health interventions equitably and sustainably to ensure that no one is left behind. The 8 principles focus on the 4 areas of a sustainable health system-human, social, economic, and environmental-and highlight the broader possibilities for using digital technology to have an impact on the sustainability of health systems.

[Implementation of telemedicine in the Americas: Barriers and facilitatorsBarreiras e facilitadores para a implementação da telemedicina nas Américas]. / Barreras y facilitadores a la implementación de la telemedicina en las Américas.

With millions of people in the world in situations of physical distancing because of COVID-19, information and communication technology (ICT) has become as one of the principal means of interaction and collaboration. The following advantages of ICT have been cited since the start of the new millennium: increased access to information and service delivery, educational strengthening, quality control of screening programs, and reduction of health care costs. In the case of telemedicine, however, a number of barriers-especially technological, human and social, psychosocial, anthropological, economic, and governance-related-have stood in the way of its adoption. The past 20 years have seen an increase in the availability of resources and technical capacity, improvements in digital education, empowerment of patients regarding their treatment, and increased public interest in this area. Successes have included the use of interdisciplinary teams, academic and professional networking, and virtual medical consultations. After reviewing the state of telemedicine in the Region of the Americas, the authors recommend the urgent adoption of measures aimed at implementing national telemedicine policies and programs, including a regulatory framework and adequate funding. Implementation of the measures should be integrated and interoperable and include the support of academic networks and the collaboration of specialized institutions. The policies should generate an enabling context that ensures sustainability of the progress achieved, bearing in mind the possible barriers mentioned.

Com milhões de pessoas no mundo em situação de distanciamento físico devido à COVID-19, as tecnologias da informação e comunicação (TICs) se enquadraram como um dos meios principais de interação e colaboração.

No entanto, entre as principais barreiras de adoção da telemedicina se encontram as de caráter: tecnológico; humano e social; psicossocial e antropológico; de governança e econômico. Nestes 20 anos, houve um aumento nos recursos e na capacidade técnica, uma melhora na educação digital, um empoderamento do paciente em seu tratamento e um maior interesse público nessa área. Em especial, são consideradas bem-sucedidas a constituição de equipes interdisciplinares e as redes acadêmicas e profissionais, e as consultas médicas virtuais. Após revisar o estado da telemedicina na Região das Américas, os autores recomendam a adoção de medidas urgentes para implementar políticas e programas nacionais de telemedicina, incluindo o marco normativo e o orçamento necessário. Essa implementação deve ser realizada de maneira integral e interoperável e sustentada por redes acadêmicas, de parceria e instituições especializadas.

Infodemia en tiempos de COVID-19

[Extracto]. El 15 de febrero de 2020, durante la Conferencia sobre Seguridad en Múnich, el director de la Organización Mundial de la Salud (OMS), el Dr. Tedros Adhanom Ghebreyesus, indicó que a la lucha contra la epidemia por la COVID-19 se le sumaba la lucha contra la “infodemia”, dando así inicio a una serie de acciones desde la OMS y otras organizaciones para enfrentar este desafío. Esta situación no es nueva, ya que casos similares han sucedido durante otras emergencias sanitarias, pero nunca antes con la magnitud actual, producto del aumento del uso de las aplicaciones digitales. En la era de la interdependencia digital, este fenómeno se amplifica debido a la convergencia del aumento en el acceso a los dispositivos móviles, el acceso a Internet y el uso de las redes sociales, que se propagan cada vez más lejos y más rápido, como un virus.

The COVID-19 Infodemic

[Extract]. On 15 February 2020, during the Munich Security Conference, the Director of the World Health Organization (WHO), Dr. Tedros Adhanom Ghebreyesus, stated that the fight against the COVID-19 pandemic was accompanied by a fight against an “infodemic”, leading to a series of initiatives by the WHO and other organizations to face this challenge. This situation is not new: others have occurred during other health emergencies, but never one of the current magnitude, resulting from the increased use of digital applications. In the age of digital interdependence, this phenomenon is amplified by the convergence of increased access to mobile devices, internet access, and the use of social networks, which are spreading it like a virus, further and faster than ever before.

How to carry out conceptual properties norming studies as parameter estimation studies: Lessons from ecology.

Conceptual properties norming studies (CPNs) ask participants to produce properties that describe concepts. From that data, different metrics may be computed (e.g., semantic richness, similarity measures), which are then used in studying concepts and as a source of carefully controlled stimuli for experimentation. Notwithstanding those metrics' demonstrated usefulness, researchers have customarily overlooked that they are only point estimates of the true unknown population values, and therefore, only rough approximations. Thus, though research based on CPN data may produce reliable results, those results are likely to be general and coarse-grained. In contrast, we suggest viewing CPNs as parameter estimation procedures, where researchers obtain only estimates of the unknown population parameters. Thus, more specific and fine-grained analyses must consider those parameters' variability. To this end, we introduce a probabilistic model from the field of ecology. Its related statistical expressions can be applied to compute estimates of CPNs' parameters and their corresponding variances. Furthermore, those expressions can be used to guide the sampling process. The traditional practice in CPN studies is to use the same number of participants across concepts, intuitively believing that practice will render the computed metrics comparable across concepts and CPNs. In contrast, the current work shows why an equal number of participants per concept is generally not desirable. Using CPN data, we show how to use the equations and discuss how they may allow more reasonable analyses and comparisons of parameter values among different concepts in a CPN, and across different CPNs.

Application of Dynamic Fragmentation Methods in Multimedia Databases: A Review.

Fragmentation is a design technique widely used in multimedia databases, because it produces substantial benefits in reducing response times, causing lower execution costs in each operation performed. Multimedia databases include data whose main characteristic is their large size, therefore, database administrators face a challenge of great importance, since they must contemplate the different qualities of non-trivial data. These databases over time undergo changes in their access patterns. Different fragmentation techniques presented in related studies show adequate workflows, however, some do not contemplate changes in access patterns. This paper aims to provide an in-depth review of the literature related to dynamic fragmentation of multimedia databases, to identify the main challenges, technologies employed, types of fragmentation used, and characteristics of the cost model. This review provides valuable information for database administrators by showing essential characteristics to perform proper fragmentation and to improve the performance of fragmentation schemes. The reduction of costs in fragmentation methods is one of the most desired main properties. To fulfill this objective, the works include cost models, covering different qualities. In this analysis, a set of characteristics used in the cost models of each work is presented to facilitate the creation of a new cost model including the most used qualities. In addition, different data sets or reference points used in the testing stage of each work analyzed are presented.

Salud pública abierta: el camino para no dejar a nadie atrás

[RESUMEN]. En el contexto de la globalización, la salud pública requiere una cooperación continua entre todos los actores y un flujo de datos e información que facilite y apalanque esa cooperación. Sin embargo, existen aún diversas restricciones que limitan o imposibilitan el acceso a ella y su uso en beneficio de las sociedades. Debido a esto, se propone la adopción de la salud pública abierta y se exploran sus implicaciones y alcances. Se entiende por salud pública abierta los datos, la información y el conocimiento dirigidos a mejorar la salud pública, que se comparten y desarrollan a través de redes colaborativas sin restricciones de acceso y uso y con protección continua de la privacidad, seguridad y confidencialidad de los datos sensibles o que requieran especial protección.

[ABSTRACT]. In the context of globalization, public health requires continuous cooperation among all actors and a flow of data and information that facilitates and leverages that cooperation. However, there are still barriers that limit or prevent access to and use of public health for the benefit of societies. In this context, the adoption of open public health is proposed and its implications and scope are explored. Open public health is understood as data, information and knowledge aimed at improving public health, which are shared and developed through collaborative networks without restrictions on access and use and with continuous protection of privacy, security and confidentiality of sensitive data or data requiring special protection.

[RESUMO]. No contexto da globalização, a saúde pública requer a cooperação contínua entre todos os atores e um fluxo de dados e informações que facilite e aproveite da melhor forma essa cooperação. No entanto, ainda existem muitas restrições que limitam ou impedem o acesso à saúde pública e a sua utilização em benefício das sociedades. Por isso, propomos aqui a adoção da saúde pública aberta, explorando as suas implicações e possibilidades. A saúde pública aberta é entendida como o uso de dados, informações e conhecimentos para melhorar a saúde pública, compartilhados e desenvolvidos através de redes colaborativas, sem restrições de acesso ou utilização e com proteção contínua da privacidade, segurança e confidencialidade de dados sensíveis ou que precisem de proteção especial.

Registros médicos de pacientes: La digitalización ya no es una opción y debe ser una obligación / Prontuários médicos do paciente: a digitalização não é mais uma opção e deve ser uma obrigação / Patient medical records: Digitization is no longer an option and should be mandatory

Los registros médicos han ido transformándose desde ser exclusivamente basados en papel a ser, en muchos casos, exclusivamente digitales. Este cambio se ha dado gradualmente: inicialmente aislados del sistema local o nacional de información en salud y luego en proceso de integración o ya completamente interconectados con todo el sistema. Esto fue gracias al acceso de la sociedad a sistemas electrónicos que pueden comunicarse e intercambiar datos entre sí de manera ágil y tecnológicamente interoperable. Existen sin embargo aún grandes retos sobre cómo lograr esta interoperabilidad, así como el establecimiento de la seguridad, privacidad y confidencialidad de los datos; sin embargo, los registros médicos en formato digital son hoy una poderosa e indispensable herramienta para la toma de decisiones, la formulación de políticas y la adecuada gestión de la salud pública.

Os prontuários médicos foram se transformando desde ser exclusivamente em papel para ser, em muitos casos, exclusivamente digitais. Essa mudança tem acontecido gradativamente: inicialmente isolada do sistema local ou nacional de informação em saúde e depois em processo de integração ou já totalmente interligada a todo o sistema. Isso graças ao acesso da sociedade a sistemas eletrônicos que podem se comunicar e trocar dados de forma ágil e tecnologicamente interoperável. No entanto, ainda existem grandes desafios para atingir essa interoperabilidade, bem como o estabelecimento da segurança, privacidade e confidencialidade dos dados; entretanto, os prontuários em formato digital são hoje uma ferramenta poderosa e indispensável para a tomada de decisões, a formulação de políticas e a gestão adequada da saúde pública.

Medical records have been transforming from exclusively paper-based into, in many cases, exclusively digital. This change has occurred gradually: initially isolated from the local or national health information system and then in the integration process or already completely interconnected with the entire system. This is due to the society's access to electronic systems that can communicate and exchange data with each other in an agile and technologically interoperable way. However, there are still great challenges on how to achieve this interoperability and to establish data security, privacy, and confidentiality; however, medical records in digital format are today a powerful and indispensable tool for decision-making, policy formulation, and proper public health management.

EXPLORING USER EXPERIENCES OF INFORMATION SYSTEMS IN HEALTH OF PATIENT SAFETY PROGRAMS: A RAPID SYSTEMATIC REVIEW.

Patient safety is one of the most important challenges facing healthcare organizations in the world. Patient safety programs aim to avoid the events caused to the patient during their care, through strategies aimed at guaranteeing infection control, safe use of medications, equipment, clinical practice and environment. However, errors in health care are often due to weak information systems and their causes can be corrected by identifying the incidents and events presented during the care. Each country must have solid and reliable health information systems (HIS) to generate its own data, in order to monitor the different health programs and thus report on their management. In many countries, HISs are weak, incomplete and fragmented, with problems related to infrastructure, interoperability, connectivity, lack of training and availability to health care personnel. The objective of this study was to conduct a rapid systematic review of the literature about the experiences reported by users or health professionals with the Health Information Systems of Patient Safety Programs (PSP). 98 articles were identified in the Medline database, of which 5 articles with a qualitative approach were included. The results showed problems with the definition of concepts related to patient safety, fear of professionals to report events or incidents, reluctance to use HIS due to interoperability or communication problems. The qualitative studies related to HIS of the PSP are scarce and the publications found have been carried out in countries such as Iran, Taiwan, Austria, Spain and the Netherlands.

Machine learning approaches to study glioblastoma: A review of the last decade of applications.

BACKGROUND: Glioblastoma (GB, formally glioblastoma multiforme) is a malignant type of brain cancer that currently has no cure and is characterized by being highly heterogeneous with high rates of re-incidence and therapy resistance. Thus, it is urgent to characterize the mechanisms of GB pathogenesis to help researchers identify novel therapeutic targets to cure this devastating disease. Recently, a promising approach to identifying novel therapeutic targets is the integration of tumor omics data with clinical information using machine learning (ML) techniques. RECENT FINDINGS: ML has become a valuable addition to the researcher's toolbox, thanks to its flexibility, multidimensional approach, and a growing community of users. The goal of this review is to introduce basic concepts and applications of ML for studying GB to clinicians and practitioners who are new to data science. ML applications include exploring large data sets, finding new relevant patterns, predicting outcomes, or merely understanding associations of the complex molecular networks presented within the tumor. Here, we review ML applications published between 2008 and 2018 and discuss ML strategies intending to identify new potential therapeutic targets to improve the management and treatment of GB. CONCLUSIONS: ML applications to study GB vary in purpose and complexity, with positive results. In GB studies, ML is often used to analyze high-dimensional datasets with prediction or classification as a primary goal. Despite the strengths of ML techniques, they are not fail-safe and methodological issues can occur in GB studies that use them. This is why researchers need to be aware of these issues when planning and appraising studies that apply ML to the study of GB.

Integrating multivariate and geostatistical analyses for assessing the socio-environmental vulnerability of children in the vicinity of a contaminated site.

Vulnerability assessments are commonly based on complex indices that may be inappropriate for characterizing risks in small groups of people exposed to environmental hazards. The aim was to present a multivariate and geostatistical approach to explore human health risks at the individual, household and community level. First, biological and socioeconomic characteristics from 179 children were used in a cluster analysis to find groups and identify vulnerability profiles. Then, both the exposure of children to arsenic and lead in soils and their accessibility to community resources were assessed using a geospatial analysis. The results identified three vulnerability profiles among children that were not in agreement with the environmental exposure and deficit of community resources. The proposed approach helps optimize strategies to manage both environmental and social risks based on the vulnerability of the exposed population.
