Risk of SARS-CoV-2 transmission upon return to work in RNA-positive healthcare workers

BACKGROUND

Healthcare workers (HCWs) are at risk for coronavirus disease 2019 (COVID-19), and for spreading severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) amongst colleagues and patients.

AIM

To study the presence of SARS-CoV-2 RNA and possible onward transmission by HCWs upon return to work after COVID-19, and association with disease severity and development of antibodies over time.

METHODS

Unvaccinated HCWs with positive SARS-CoV-2 reverse transcriptase polymerase chain reaction (RT-PCR) were recruited prospectively. Data on symptoms were collected via telephone questionnaires on days 2, 7, 14 and 21 after a positive test. Upon return to work, repeat SARS-CoV-2 RT-PCR was performed and serum was collected. Repeat serum samples were collected at weeks 4, 8, 12 and 16 to determine antibody dynamics over time. Phylogenetic analysis was conducted to investigate possible transmission events originating from HCWs with a positive repeat RT-PCR.

FINDINGS

Sixty-one (84.7%) participants with mild/moderate COVID-19 had a repeat SARS-CoV-2 RT-PCR performed upon return to work (median 13 days after symptom onset), of which 30 (49.1%) were positive with a median cycle threshold (Ct) value of 29.2 (IQR 26.9-29.9). All HCWs developed antibodies against SARS-CoV-2. No significant differences in symptomatology and presence of antibodies were found between repeat RT-PCR-positive and -negative HCWs. Eleven direct colleagues of six participants with a repeat RT-PCR Ct value <30 tested positive after the HCW returned to work. Phylogenetic and epidemiologic analysis did not indicate onward transmission through HCWs who were SARS-CoV-2 RNA positive upon return to work.

CONCLUSIONS

HCWs regularly return to work with substantial SARS-CoV-2 RNA loads. However, this study found no evidence for subsequent in-hospital transmission.

A longitudinal study of dispositional compassion in Syrian origin young adults resettling in the Netherlands

Background

Dispositional compassion is regarded as a facet of Agreeableness, an emotional driver of prosociality, and a primary marker of adjustment. We examined changes in dispositional compassion in Syrian young adults resettling in the Netherlands, as well as the role of migration-related and demographic variables in this change.

Methods

We analyzed data from a 4-wave (T1-T4), 13-month longitudinal study ( N = 168; T1 Mage = 28.1 years, 70% male) using Latent Growth Curve Modelling (LGCM) in Mplus.

Results

Bivariate correlations indicated moderate test-retest correlations across the four waves of dispositional compassion and several correlations with the migration-related and demographic variables. A LGCM indicated a high initial level and small linear decrease in compassion over the four waves. Except for a link between pre-migration adversity and the intercept, the migration-related and demographic variables were not related to either the intercept of the slope of dispositional compassion.

Conclusion

Results suggest that high levels of dispositional compassion may be common for Syrian young adults with refugee backgrounds, but on average, slowly decreases over time. The cross-sectional associations between migration-related and demographic variables and dispositional compassion in the absence of a prospective one emphasize the importance of longitudinal research for understanding trajectories of adjustment.

Lessons learned from conducting a study of emotions and positive personality change in Syrian origin young adults who have recently resettled in the Netherlands

Post-traumatic growth is a compelling idea, yet extant research has often employed retrospective reports of change, rather than examining change over time. Research on samples of people that are traditionally seen as hard-to-reach are rare within personality psychology. In Karakter, we assessed a sample of Syrian origin young adults who recently resettled in the Netherlands (initial  N = 168) four times over a 13-month period to examine experiences of adversity, emotions, and positive personality change. Here, we provide a detailed narrative of the research process, beginning with a description of how we incorporated open science practices in Karakter. We then turn to a discussion of the changes, challenges, and opportunities we encountered in the research. In doing so, we discuss conceptual and methodological considerations when examining personality change. We close with suggestions for researchers who are interested in conducting similar studies with populations that are underrecruited in the future.

Post-traumatic growth as positive personality change: Challenges, opportunities, and recommendations

OBJECTIVE

Post-traumatic growth typically refers to enduring positive psychological change experienced as a result of adversity, trauma, or highly challenging life circumstances. Critics have challenged insights from much of the prior research on this topic, pinpointing its significant methodological limitations. In response to these critiques, we propose that post-traumatic growth can be more accurately captured in terms of personality change-an approach that affords a more rigorous examination of the phenomenon.

METHOD

We outline a set of conceptual and methodological questions and considerations for future work on the topic of post-traumatic growth.

RESULTS

We provide a series of recommendations for researchers from across the disciplines of clinical/counseling, developmental, health, personality, and social psychology and beyond, who are interested in improving the quality of research examining resilience and growth in the context of adversity.

CONCLUSION

We are hopeful that these recommendations will pave the way for a more accurate understanding of the ubiquity, durability, and causal processes underlying post-traumatic growth.
