Background Neurological COVID-19 disease has been reported widely, but published studies often lack information on neurological outcomes and prognostic risk factors. We aimed to describe the spectrum of neurological disease in hospitalised COVID-19 patients; characterise clinical outcomes; and investigate factors associated with a poor outcome. Methods We conducted an individual patient data (IPD) meta-analysis of hospitalised patients with neurological COVID-19 disease, using standard case definitions. We invited authors of studies from the first pandemic wave, plus clinicians in the Global COVID-Neuro Network with unpublished data, to contribute. We analysed features associated with poor outcome (moderate to severe disability or death, 3 to 6 on the modified Rankin Scale) using multivariable models. Results We included 83 studies (31 unpublished) providing IPD for 1979 patients with COVID-19 and acute new-onset neurological disease. Encephalopathy (978 [49%] patients) and cerebrovascular events (506 [26%]) were the most common diagnoses. Respiratory and systemic symptoms preceded neurological features in 93% of patients; one third developed neurological disease after hospital admission. A poor outcome was more common in patients with cerebrovascular events (76% [95% CI 67–82]), than encephalopathy (54% [42–65]). Intensive care use was high (38% [35–41]) overall, and also greater in the cerebrovascular patients. In the cerebrovascular, but not encephalopathic patients, risk factors for poor outcome included breathlessness on admission and elevated D-dimer. Overall, 30-day mortality was 30% [27–32]. The hazard of death was comparatively lower for patients in the WHO European region. Interpretation Neurological COVID-19 disease poses a considerable burden in terms of disease outcomes and use of hospital resources from prolonged intensive care and inpatient admission; preliminary data suggest these may differ according to WHO regions and country income levels. The different risk factors for encephalopathy and stroke suggest different disease mechanisms which may be amenable to intervention, especially in those who develop neurological symptoms after hospital admission.

During the emergence of the novel COVID-19, a proliferation of memes related to events discussed in Spanish-speaking social media was observed. This study analysed the four stages of collective coping to determine how memes became triggered social representations that gradually monopolized the mainstream media. The research was performed through an electronic survey of 351 participants from Puerto Rico, which was subsequently analysed through partial least squares structural equation modeling (PLS-SEM). The study’s results reflected psychological implications in the use of memes in terms of how they were used to mitigate the stressful circumstances of a social event. This study is a pioneer in the application of Collective Coping Theory in the context of the effects that memes produce as a link to mitigate stressors. It also discusses how, when a culture faces a problem, memes become a decisive means to reinterpret the situation.

Purpose The purpose of this paper is to examine the use of social media and its impact on information search, communication with a company, and purchase and re-purchases of products and services. Using use and gratification theory as a starting point, it also examines the impact of satisfaction of use of social media in the process of purchasing and re-purchasing products and services. Design/methodology/approach An online survey was conducted with 444 participants, and the data were analyzed using the partial least squares structural equation modeling technique to observe the effects between the variables of social media use, search information, communication with the company, purchase, re-purchase and satisfaction of use of social media. Findings The results reflect how the use of social media generates significant rewards that significantly impact the search for information and the communication with the company. The data also show how communication with the company has an impact on the purchase and re-purchase of products and services. Finally, it was empirically confirmed that the gratification received by users through social media use impacts satisfaction with social media use. Originality/value The results contribute to how social media impacts alternative evaluations through the gratification of user needs, resulting in motives and behaviors leading to the purchase of goods and services, as established by Use and Gratification Theory. In its contributions to the Academy, Use and Gratification Theory (U&G) explains why individuals use and share information using social media. First, it justifies the purchase and re-purchase of products and services due to user satisfaction according to users’ experience using social media. Second, it presents a vision of how the use of social media is a significantly important result in the gratification of consumer needs.

PurposeThe aim of this study was to analyse the relationship between organizational citizenship and commitment in a sample of employees of banking branches in Puerto Rico. The specific objectives were to identify the practices of organizational citizenship and determine the relationship of altruism, awareness, courtesy, tolerance and civil virtue with organizational commitment.Design/methodology/approachThe research design was quantitative, descriptive, correlational and transversal. The research instrument was validated and obtained high coefficients.FindingsThe results confirm a significant statistical relationship between awareness, civil virtue, tolerance and altruism with organizational commitment.Research limitations/implicationsThis research has a positive impact on companies in increasing their finances with intangible strategies, and leadership styles can evolve towards civility. It suggests modifying the university curricula to prepare managers with intangible supervisory and performance management strategies through workshops, seminars and professional conferences.Practical implicationsOrganizations and employees develop their own traits and establish patterns of citizenship behaviour that allow them to create passionate and committed employees.Social implicationsThe research was able to predict that citizenship is related in a positive way to reach operational goals and fostering an atmosphere and image of cordiality as a success strategy. The contribution to the organizational policy can be established in the development processes among partners, in training, regulations and policies. It provides the academic contribution of the model.Originality/valueThis is the first attempt to evaluate citizenship behaviour in the banking industry in Puerto Rico.

This research examines data on 454 participants from the millennial generation. Through the theory of uses and gratifications, the researchers analyze how content strategies employed by the Snapchat impact the use and sharing of content. In addition, motivations for impulsive purchases are analyzed. This exploratory study uses quantitative methodology through an applied survey. The researchers make use of partial least squares structural equations (SMART-PLS). The results contribute to the theory through the identification of gratification factors such as interaction, relationship management, purchase savings, information, interactivity, easy access to content, distraction, creativity, fun and dynamism.
