Bite-sized self-compassion: a pilot cohort study of a well-being tool for healthcare workers
2025
Healthcare worker (HCW) well-being is an urgent priority in the wake of the COVID-19 Pandemic. Poor worker well-being has been linked to greater turnover, lower quality of care, and higher patient safety risks. Brief, simple tools to increase HCW well-being are of considerable interest. The current pilot study examined a bite-sized Self-compassion Tool (SCT) for HCWs. 216 participants completed baseline resilience measures (Emotional Thriving and Emotional Recovery), engaged in the SCT (5–7 min in length), and the following day, completed post resilience and tool evaluation measures. Participants reported significant improvements in Emotional Recovery, which is the ability to bounce back from adversity. Participants did not report changes in Emotional Thriving, however they did evaluate the tool favorably. This pilot study offers promising evidence for the efficacy of the SCT. HCWs are in need of brief tools alongside system changes to improve overall well-being, turnover, and patient care.

The purpose of this concept delineation was to differentiate similar concepts impacting nurse well-being during the COVID-19 pandemic, including: compassion fatigue, burnout, moral injury, secondary traumatic stress, and second victim.
A total of 63 articles were reviewed for concept delineation. Morse's (1995) approach to concept delineation was utilized to analyse the articles.
Concepts were described interchangeably but were found to present themselves in a sequence. A nurse may experience moral injury, leading to a second victim experience, synonymous with secondary traumatic stress, then compassion fatigue and/or burnout that can be acute or chronic in nature. An Occupational Trauma Conceptual Model was created to depict how these concepts interact based on concept delineation findings.
Nurses are experiencing long-lasting occupational trauma and future intervention research should centre on optimizing nurse well-being to ensure the sustainability of nursing profession.

ObjectiveThis qualitative study aimed to identify categories within therapeutic self-compassion letters written by healthcare workers. Resulting categories were assessed for their relevance to the construct of self-compassion.DesignThis was a qualitative descriptive study that used summative content analysis and inductive coding.SettingA US-based academic healthcare system.ParticipantsHealthcare workers who attended a self-compassion webinar were recruited.InterventionThe online self-compassion tool asked participants to write a letter to themselves from the perspective of a friend providing support and encouragement.Results116 letters were analysed. Five major categories emerged: Looking Forward, Reaffirming Self, Reaffirming Reminders, Hardships and Self-Disparagement. Respondents’ letters were mostly positively framed and forward thinking, including their hopes of improving themselves and their lives in the future. Negative content generally described hardships and often served to provide self-validation or perspective on obstacles that had been overcome.ConclusionThe writing prompt elicited content from the writers that reflected the core elements of self-compassion (ie, self-kindness, common humanity, mindfulness). Continued research to further understand, refine and improve the impact of therapeutic letter writing to enhance well-being is warranted to reduce burnout and promote quality patient care.

Olfactory receptor axons reinnervate the olfactory bulb (OB) after chemical or transection lesion. Diffuse brain injury damages the same axons, but the time course and regulators of OB reinnervation are unknown. Gelatinases (matrix metalloproteinase [MMP]2, MMP9) and their substrate osteopontin (OPN) are candidate mediators of synaptogenesis after central nervous system (CNS) insult, including olfactory axon damage. Here, we examined the time course of MMP9, OPN, and OPN receptor CD44 response to diffuse OB injury. FVBV/NJ mice received mild midline fluid percussion insult (mFPI), after which MMP9 activity and both OPN and CD44 protein expression were measured. Diffuse mFPI induced time-dependent increase in OB MMP9 activity and elevated the cell signaling 48-kD OPN fragment. This response was bimodal at 1 and 7 days post-injury. MMP9 activity was also correlated with 7-day reduction in a second 32-kD OPN peptide. CD44 increase peaked at 3 days, delayed relative to MMP9/OPN response. MMP9 and OPN immunohistochemistry suggested that deafferented tufted and mitral neurons were the principal sites for these molecular interactions. Analysis of injured MMP9 knockout (KO) mice showed that 48-kD OPN production was dependent on OB MMP9 activity, but with no KO effect on CD44 induction. Olfactory marker protein (OMP), used to identify injured olfactory axons, revealed persistent axon damage in the absence of MMP9. MMP9 KO ultrastructure at 21 days post-injury indicated that persistent OMP reduction was paired with delayed removal of degenerated axons. These results provide evidence that diffuse, concussive brain trauma induces a post-injury interaction between MMP9, OPN, and CD44, which mediates synaptic plasticity and reinnervation within the OB.

Beyond Burnout: Nurses’ Perspectives on Chronic Suffering During and After the COVID-19 Pandemic
2024
Nurses around the globe have been impacted psychologically and emotionally during and after the COVID-19 pandemic. The purpose of this study was to describe nurses’ perspectives on the concepts of compassion fatigue, second victimhood, burnout, and moral injury. Eight nurses were interviewed either individually or in groups of two. Data were analyzed using conventional content analysis. The following themes were identified: waves of compassion fatigue, traumatization within second victimhood, never the same after chronic burnout, moral injury: nurses couldn’t do their best, and connections across concepts. Results showed nurses were most familiar with burnout and compassion fatigue, which remain chronic struggles. Second victimhood and moral injury were more distinct experiences related to traumatic or morally distressing events and likely contributed to experiencing burnout or compassion fatigue. Nurses’ suffering heightened during the COVID-19 pandemic and remains prominent three years later. Future research and interventions are urgently needed globally to reduce workplace stressors and promote nurse well-being.

Ceratitis capitata
2025
This study evaluates the potential of quantum dots (QDs) as a marking method for Mediterranean fruit flies (Ceratitis capitata) (Medfly) in comparison to traditional fluorescent powder. As a highly destructive pest impacting a wide variety of fruit crops, an effective marking technique is essential for improving the biological understanding and management of Medflies, including control strategies like the Sterile Insect Technique (SIT). Through multiple controlled experiments, we examined the effects of QDs and fluorescent powder markers on Medfly flight ability, marker retention rates, and marker durability and stability under diverse storage conditions. Fluorescent powder demonstrated consistently high reliability across all parameters, whereas QDs showed reduced retention, particularly when applied to pupae, and had a more pronounced negative effect on flight ability. This was illustrated by the field trials, which did not recapture any of the QD-marked flies, highlighting the current limitations in QD application methods. Additionally, fluorescent powders outperformed QDs in both long-term storage conditions and short-term stability tests. These findings indicate that while QDs possess potential as marking agents, further refinement of application techniques is required to achieve comparable efficacy to fluorescent powders in pest management contexts.

Collaboration
2024
Collaborations are critical to address rural health challenges. We evaluated a new international collaboration between institutions in Georgia, the United States (US), and Scotland, United Kingdom (UK), to address rural health issues and to understand the barriers and facilitators to effective international collaboration efforts. A qualitative approach was used through in-depth interviews and focus groups with educators, researchers, and healthcare providers in the US and Scotland who were involved in the CONVERGE international rural health collaboration. Transcriptions were imported into the NVivo qualitative software program. A reflexive thematic analysis was employed to identify key themes from the collected data. Twelve interviews and two focus groups were conducted virtually with 17 participants. Two primary domains were identified from the thematic analysis: (1) motivators that increase engagement in international collaboration, and (2) mechanisms for, and barriers to, the continuity needed to create meaningful change. Six themes emerged related to commonality of issues, prospect of sharing knowledge, need of sustained funding and institutional support, and selection of human resources. Participants of CONVERGE were more likely to engage when they had a space to share ways to address challenging issues and integrate knowledge and practice. They were motivated by their desire for growth and the institutions they serve and emphasized that infrastructure support is vital for sustainable collaborations.

Obesity among children is increasing nationwide, and creative solutions beyond traditional programs designed exclusively by academics are needed to achieve lasting success. One innovative approach that departs from the typical model of exclusive academic design incorporates local community input in designing health-related programs. Such input can lead to more relevant programs and community \"buy in,\" thereby increasing the likelihood of the effectiveness of the program. One approach that incorporates local community input is called community-based participatory research (CBPR) whereby researchers and community partners work together and use the CBPR principles to create and sustain culturally relevant, impactful programs.
This paper describes how a mixed-methods CBPR approach was used to formulate and implement a needs assessment survey, and how mini-focus groups were used to reinforce the survey findings.
A survey seeking information about physical activity (PA) and dietary behavior was given to 27 families at a school-based event, and a forward stepwise regression was run to identify significant determinants. The results were presented and discussed with community mini-focus groups (n = 20).
The regression models were significant (P < 0.05), where parental support of PA and PA beliefs were significant determinants of moderate to vigorous PA, and water intake, whole grain intake, and fruit and vegetable consumption were the top three significant determinants of dietary behavior. Mini-focus groups reinforced the model results.
This approach helped identify the determinants that should be addressed when designing an after school program targeting PA and dietary behavior for minority students attending a school in an underserved community.

Beyond the Spectacle of Suffering: Agnès Varda's L'Une chante, l'autre pas and Rewriting the Subject of Abortion in France
2020
In the spring of 1971, three years after the revolutionary fervor of May 1968 in France, 343 women put their names to a courageous manifesto announcing that they were criminals of a particularly gendered nature. The authors of Manifeste des 343 (Manifesto of the 343) comprised a large group of culturally eminent French women and activists declaring that they had all illegally undergone abortions, which at this point, despite growing decriminalization throughout much of Western Europe, were still outlawed within their republic. Though many of the revolutionary fires had now eased to embers, French feminists demonstrated that reproductive rights were still a vital and unresolved topic of social justice. Including names as weighty as Simone de Beauvoir, Jeanne Moreau, and Catherine Deneuve, the manifesto brought together exceptional women from the fields of academia, law, theater, film and literature, alongside grassroots activists. Their action was a bold challenge to the French authorities, daring them to arrest some of the country's brightest thinkers and cultural innovators under a law the signatories felt was deeply unjust, sexist, and antithetical to the values of individual liberty and citizenship. It was a case of those with the broadest shoulders weaponizing their privilege to present a robust front line in the wider struggle for women's rights.One of the signatories was filmmaker Agnes Varda. Her name, like those of several others on the list, demonstrates the symbiosis between cultural production and gender politics that has often characterized French feminist thought. From the multidisciplinary writings of Beauvoir, to the novels of the écriture feminine movement, to the lyrical academic prose of Hélene Cixous, Luce Irigaray, Julia Kristeva, and others, French and Francophone feminist writers have tended to connect art and politics with a great deal of fluidity. As a committed activist and a filmmaker, Agnes Varda falls very much within this tradition, often adopting and developing feminist practices within her cinema. This article examines how Varda's 1977 film, L'Une chante, l'autre pas (One Sings, The Other Doesn't) interacts with and participates in the feminist political project of reproductive rights as well as the ongoing intellectual and moral debates over abortion taking place in France throughout the late 1960s and 1970s. I look particularly at the adversarial construction of abortion narratives within these debates and the location of victimhood therein. Within mainstream cultural representations in and beyond France, abortion is typically constructed as either a traumatic or a transgressive moment. The same is often true on either side of political and social debates on abortion, which have tended either to characterize the women who get abortions as irresponsible and amoral or as sympathetic victims in need of protection. Though the transgressive element persists, it is the interaction with representations of trauma that interests me here.In approaching discussions of gendered injustice, it is common for feminist writers and activists to leverage pathos as a rhetorical strategy. While suffering can be a highly effective and galvanizing expression of oppression, such discourses also run the risk of producing excessive depictions of victimhood, which can displace the capacity for action from the subject of hardship onto the privileged oppressor. This risk is particularly at stake within the cultural form of film, as its visuality and identificatory mechanics have the potential to spectacularize the female victim and make her relatable only through suffering. This was often the case in earlier French films that featured abortion such as Les Mauvaises rencontres (1955), Des gens sans importance (1956), Journal d'une femme en blanc (1965), and Une femme en blanc se revolte (1966), all of which made their subjects sympathetic by entwining them in long narratives of victimization ending in death or disgrace. This article looks at how Varda's L'Une chante, l'autre pas disengages from the spectacle of suffering that so often characterizes representations of women's experiences and rejects the idea that abortion narratives must manifest through the adversarial axis of villain and victim. Rather than producing critique only by subverting this binary and moving the woman undergoing abortion to its opposite pole - from perpetrator to victim -Varda's approach dismisses the need for such a binary altogether.Though L'Une chante has historically been overlooked within scholarship on Varda's work, it has seen a resurgence of interest in recent years and has begun to demonstrate a lively legacy among contemporary feminists. It is timely, therefore, to explore the complexities of this long-neglected work. I argue that the film takes an important, deconstructive approach toward narratives of gendered injustice, abortion in particular, that calls into question representational expectations of women's suffering. This article will proceed in four parts, with the first two giving an overview of the political climate around abortion in France, before moving on to a close analysis of Varda's film itself.
