The ␣4␤7 integrin plays a central role in the homing of T cells to the gut. We hypothesized that absence of the ␤7 subunit would result in a reduction of intestinal graft-versus-host disease (GVHD) and an improvement in overall GVHD morbidity and mortality in recipients of hematopoietic stem cell transplantation (HSCT). Analysis of alloreactive ␤7 ؊/؊ T cells showed intact activation, proliferation, cytokine production, and cytotoxicity. However, recipients of ␤7 ؊/؊ donor T cells in murine HSCT models experienced less GVHD morbidity and mortality than recipients of wild-type (WT) T cells, associated with a decrease in donor T-cell infiltration of the liver and intestine and with an overall significant decrease in hepatic and intestinal GVHD. In graft-versustumor (GVT) experiments, we demonstrated intact or even enhanced GVT activity of ␤7 ؊/؊ donor T cells. In conclusion,

CF and BO may impact emotional well-being and professional performance of neonatologists. Enhancement of CS is a potential target for intervention.

The survey response rate was 39%, primarily consisting of female, Caucasian providers. The prevalence of CF, BO, and CS was 18%, 12%, and 25%, respectively. Distress about a "clinical situation," physical exhaustion, and personal loss were identified as significant determinants of CF. Distress about "coworkers," emotional depletion, social isolation, and "recent involvement in a clinical situation in which life-prolonging activities were not introduced" were significant determinants of BO. Physical exhaustion, personal history of trauma, "recent involvement in a clinical situation in which life-prolonging activities were not introduced," and not discussing distressing issues were significant predictors of lower CS scores. Significance of results CF and BO directly influence the well-being and professional performance of PPC providers. To provide effective compassionate care to patients, PPC providers must be attentive to predictors of these phenomena. Further work is needed to explore additional causes of CF, BO, and CS in PPC providers as well as potential interventions.

Objectives: To determine the prevalence of compassion fatigue, burnout, and compassion satisfaction and identify potential personal and professional predictors of these phenomena in pediatric critical care providers. Design: Cross-sectional, online survey. Setting: Pediatric critical care practices in the United States. Subjects: Pediatric critical care fellows and attending physicians. Interventions: None. Measurement and Main Results: A modified Compassion Fatigue and Satisfaction Self-Test for Helpers and a questionnaire of personal and professional characteristics were distributed electronically to pediatric critical care physicians nationally. Prevalence of these phenomena was calculated. Hierarchical linear regression models for compassion fatigue, burnout, and compassion satisfaction as a function of potential risk factors were constructed. The survey response rate was 35.7%. The prevalence of compassion fatigue, burnout, and compassion satisfaction was 25.7%, 23.2%, 16.8%, respectively. Burnout score, emotional depletion, and distress about a patient and/or the physical work environment were each significant determinants of higher Compassion Fatigue scores. Preparing for didactics, Compassion Fatigue score, distress about administrative issues and/or coworkers, and “self-care is not a priority” were each significant determinants of higher burnout scores, whereas female sex, Compassion Satisfaction score, and distress about the physical work environment were each significant determinants of lower burnout scores. Prayer/meditation, talking with colleagues, senior faculty level, and student and/or chaplain involvement when delivering bad news were each significant predictors of higher Compassion Satisfaction scores, whereas female sex, burnout score, emotional depletion, and distress about coworkers were each significant predictors of lower Compassion Satisfaction scores. Conclusions: In our population, chronic exposure to distress in patients and families puts pediatric critical care physicians at risk for compassion fatigue and low compassion satisfaction. Awareness of compassion fatigue, burnout, and compassion satisfaction and their predictors may benefit providers both personally and professionally by allowing them to proactively manage their distress.

AYA self-identities evolve during the illness experience. When words such as "religion" and "spirituality" do not fit, explicitly exploring hopes, worries, meaning, and changing life perspectives may be a promising alternative.

Over the past two decades, paediatric palliative care has emerged as both a primary approach and as its own medical subspecialty, the overall aim of which is to ease suffering for children with life-threatening illness and their families through a concurrent model of care. However, most discussions have been focused on the transition to palliative care when no realistic hope for cure exists. We believe that, because the course of cancer is so unpredictable, this idea is misleading. Indeed, palliative care is increasingly being recognized as being about not just how to cope with the process of dying, but also about how to engage in living when faced with a life-threatening illness. This article will examine our current understanding of several areas of palliative care, with the ultimate message that palliative care is simply a novel term for the total care of a child and family, an approach that should be applied consistently and concurrently regardless of disease status. By improving familiarity with palliative care and building relationships with palliative care specialists, the paediatric oncology clinician will ensure that the best care possible for children and families is provided, regardless of outcome.

Objectives:The objective was to determine the prevalence of compassion fatigue (CF), burnout (BO), and compassion satisfaction (CS) and identify potential personal and professional predictors of these phenomena in pediatric emergency medicine (PEM) physicians.Methods: A modified Compassion Fatigue and Satisfaction Self-Test for Helpers and a questionnaire of personal and professional characteristics were distributed electronically to PEM physicians nationally. The prevalence of these phenomena was calculated. Hierarchical linear regression models for CF, BO, and CS as a function of potential risk factors were constructed. Results:The final analyzable survey rate represented 22.7% of the physicians invited to participate. The prevalences of CF, BO, and CS were 16.4, 21.5, and 18.5%, respectively. BO score, distress about a "clinical situation," "physical work environment," and engaging in prayer/meditation were each significant determinants of higher CF scores, whereas "socializing with family/friends" was significantly associated with lower CF scores. CF score, emotional depletion, and distress due to "coworkers" were each significant determinants of higher BO scores, whereas CS score and "talking with a family member" as a means of self-care were significantly associated with lower BO scores. Socializing with family/friends and >20 years as PEM provider were each significant determinants of higher CS scores, whereas BO score, emotional depletion, distress about the physical work environment and "administrative issues," 10% to 24% of time spent caring for pediatric patients, and "talking with life partner" about work-related distress were each significant determinants of lower CS scores. We acknowledge that the generalizability of our findings is limited by the sample size and by the fact that participants were largely female, Caucasian, and junior faculty and worked in academic medical centers.Conclusions: PEM physicians are at risk for developing CF, BO, and low CS. Proactive awareness of these phenomena and their predictors may allow providers to better manage the unique challenges and emotional stressors of the pediatric ED to enhance personal well-being and professional performance. P ediatric emergency medicine (PEM) physicians function at the frontline of pediatric health care, and with this privilege comes a distinct set of challenges and emotional stressors. While providing medical care for acutely ill children and working closely with families at a time of heightened stress,

Compassion fatigue (CF), burnout (BO), and compassion satisfaction (CS) are interrelated phenomena that impact personal and professional performance. The CF and Satisfaction Self-Test and a demographic questionnaire were distributed electronically to pediatric hematology-oncology physicians nationally. Linear regression models for CF, BO, and CS as a function of potential predictors were constructed. Survey response rate was 28%. Female sex, BO score, distress about a “clinical situation,” and “teaching” were associated with higher CF scores. “Administrative activities” were associated with lower CF scores. CF score, and distress about “administrative burden/academic stress” and “coworkers” were associated with higher BO scores. CS score and “socializing” were associated with lower BO scores. “Exercise,” “socializing,” and “talking with partner” were associated with higher CS scores. CF and BO scores, emotional depletion, and distress about the “work environment” and “administrative/academic burden” were associated with lower CS scores. Our data highlights the importance of strong social connections at work and at home to decrease BO and enhance CS. Professional development in leadership, communication, and conflict resolution, as well as “team building” events may perpetuate coworker relationships. Education about the importance of connectedness and self-care should begin early in medical education to cultivate robust coping mechanisms in trainees.
