Metaviromic reveals the dynamics and diversity of the virosphere in wastewater samples from Natal, Brazil

The COVID-19 pandemic underscored the significance of omics technology and Wastewater-Based Epidemiology for epidemic preparedness. This study investigates the virosphere in wastewater samples from Natal (Brazil), aiming to understand its structure, relationships, and potential. Metaviromic analysis was used on DNA and RNA from weekly samples collected over a year (June/2021 to May/2022) from three wastewater treatment plants. The virosphere showed stability, particularly in viruses infecting microorganisms and plants. However, an alternation of representatives of viruses that infect animals has been observed. Among the most abundant viruses infecting microorganisms are genera associated with the bacterial genera Escherichia, Pseudomonas, and Caulobacte. Regarding the viruses infecting plants, Sobemovirus and Tobamovirus are the most abundant genera. Odontoglossum ringspot virus was identified as a possible RNA virus biomarker. Among DNA viruses infecting animals, genera Bocaparvovirus and Mastadenovirus are the most prevalent. Intriguingly, some Poxviridae family members were observed in the samples. Co-occurrence network analysis identified potential biomarkers like Volepox virus, Anatid herpesvirus 1, and Caviid herpesvirus 2. Among RNA viruses affecting animals, Mamastrovirus, Rotavirus, and Norovirus genera were the most abundant pathogens. Furthermore, members of the Coronaviridae family exhibited a high degree of centrality values in the co-occurrence network, even connecting with unclassified viruses. The study emphasizes the importance of research in understanding the roles of unclassified viruses. In addition, we observed an association between Coronaviridae reads, rainfall, and the number of reported COVID-19 cases. Our study highlights the diversity and complexity of the viral community in wastewater and the need for research to understand better the ecological roles unclassified viruses play. Such advances will significantly contribute to our preparedness and response to future viral threats. Furthermore, our study contributes to knowledge of virosphere dynamics, offering insights that can contribute to the direction of future public health policies and interventions.

Organizational learning during COVID-19: A qualitative study of nurses' experiences

Aim

The aim of this study is to test the validity of the Organizational Learning in Hospitals model in the context of the COVID‐19 pandemic.

Background

Organizational learning is especially crucial in circumstances of intense, complex, enduring change, as with the COVID‐19 pandemic. Nurse managers need additional guidance for fostering organizational learning under such circumstances. The Organizational Learning in Hospitals model may be a helpful resource but requires additional validation.

Methods

Semi‐structured interviews were conducted to gather 19 nurses' first‐hand experiences of organizational learning during the COVID‐19 pandemic. Data were analysed using deductive thematic analysis.

Results

Nurses' experiences of organizational learning generally aligned with the tenets of the model. Specifically, effective organizational learning occurred when the contextual factors and mechanisms portrayed in the model converged. Model and contrary cases illustrate this phenomenon.

Conclusions

This study validates and adds context to the model. It offers practical examples of the contextual factors and mechanisms of organizational learning. Leaders can use the model to guide their efforts to foster organizational learning.

Implications for Nursing Management

This study reaffirms the importance of nurse leaders' central role in organizational learning. Nurse leaders can use the Organizational Learning in Hospitals model, and the practical examples provided, to foster organizational learning during challenging times.
