To explore the impact of COVID-19 on students' lives and their online learning experience.
A cross-sectional survey design was used in this study.
A total of 44 nursing students who were enrolled in an undergraduate programme at a Canadian University participated in the study. The students were asked to fill out a 35-item survey that was developed by the European Students' Union and that was circulated across Europe in April 2020.
The COVID-19 pandemic and subsequent lockdown affected students mentally, and emotionally. Findings also revealed that whilst most students had the privilege to study from home, many students did not have a desk, or a quiet place to study in their home and some had problems with Internet connectivity. Online lectures were delivered according to students' preferences; however, students were dissatisfied with the way their practice was organized.
The similarities between this study and the European study provide common grounds for academics around the world to connect, collaborate and work on the challenges in providing nurse education in emergencies such as national disasters or pandemics to ensure preparedness for such future events.
No Patient or Public Contribution.
The commonalities experienced in nursing education across the globe should act as an impetus for globalized nursing action. Educators need to prepare and reinvent a role for students in the clinical area in the event of future disasters/pandemics. Policy makers and administrators need to ensure when switching to online education no student is underprivileged or marginalized in the process.

Wildlife is subject to various sources of pollution, including ionizing radiation. Adverse effects can impact the survival, growth, or reproduction of organisms, later affecting population dynamics. In invertebrates, reproduction, which directly impacts population dynamics, has been found to be the most radiosensitive endpoint. Understanding the underlying molecular pathways inducing this reproduction decrease can help to comprehend species-specific differences in radiosensitivity. From our previous studies, we found that decrease in reproduction is life stage dependent in the roundworm Caenorhabditis elegans, possibly resulting from an accumulation of damages during germ cell development and gamete differentiation. To go further, we used the same experimental design to assess more precisely the molecular determinants of reproductive toxicity, primarily decreases in gamete number. As before, worms were chronically exposed to 50 mGy·h−1 external gamma ionizing radiation throughout different developmental periods (namely embryogenesis, gametogenesis, and full development). To enable cross species extrapolation, conserved molecular pathways across invertebrates and vertebrates were analysed: apoptosis and MAP kinase Ras/ERK (MPK-1), both involved in reproduction and stress responses. Our results showed that these pathways are life-stage dependent, resulting from an accumulation of damages upon chronic exposure to IR throughout the life development. The Ras/ERK pathway was activated in our conditions in the pachytene region of the gonad where it regulates cell fate including apoptosis, but not in the ovulation zone, where it controls oocyte maturation and ovulation. Additionally, assessment of germ cell proliferation via Ras/ERK pathway showed no effect. Finally, a functional analysis of apoptosis revealed that while the decrease of the ovulation rate is caused by DNA-damaged induced apoptosis, this process does not occur in spermatocytes. Thus, sperm decrease seems to be mediated via another mechanism, probably a decrease in germ cell proliferation speed that needs further investigation to better characterize sex-specific responses to IR exposure. These results are of main importance to describe radio-induced reprotoxic effects and contribute as weight of evidence for the AOP #396 “Deposition of ionizing energy leads to population decline via impaired meiosis”.
