Circulating endocannabinoids during hematopoietic stem cell transplantation: A pilot study

AbstractObjectiveHematopoietic stem cell transplantation (HCT) is a stressful and rigorous medical procedure involving significant emotional and immune challenges. The endocannabinoid (eCB) signaling system is involved in regulation of both the immune system and emotional reactivity, yet little is known about its function during HCT. We investigated the role of the eCB signaling system in a group of HCT recipients.MethodsA total of 19 HCT recipients were enrolled and provided psychosocial data and blood samples at three peri-transplant time points: prior to transplant, hospital discharge, and approximately 100 days post-transplant. Psychosocial factors, inflammatory molecules, and the eCBs were determined and assessed for changes over this period and association with each other.ResultsHCT recipients demonstrated significant changes over the peri-transplant period in inflammatory molecules and psychosocial functioning, but not in circulating concentrations of the eCBs. Associations among these variables were most likely to be present pre-transplant and least likely to be present immediately post-transplant, with depressive symptoms and inflammation most significantly associated. The eCB 2-arachidonoylglycerol (2-AG) was significantly, positively associated with both interleukin (IL)-6 and C-reactive protein (CRP) and negatively associated with depressive symptoms.ConclusionsThe eCB signaling system may have alternative sources and regulatory mechanisms in addition to the immune system. Given the significant associations with inflammatory molecules and depressive symptoms in the peri-transplant period, it is important to better understand this system and its potential implications in the setting of complex and stressful medical procedures such as HCT

Music Therapy as an Adjunctive Treatment in the Management of Stress for Patients Being Weaned from Mechanical Ventilation

This project investigated music therapy (MT) in managing anxiety associated with weaning from mechanical ventilation. The use of sedation to treat anxiety during weaning is problematic because side effects (e.g., respiratory depression) are precisely the symptoms that cause the weaning process to be interrupted and consequently prolonged. Study goals were to determine the feasibility of incorporating MT into the weaning process and to evaluate the efficacy of the intervention, based on levels of anxiety, Days to Wean (DTW), and patient/nurse satisfaction. Adult patients received multiple MT sessions per week while undergoing weaning trials from mechanical ventilation. Feasibility was determined by successful enrollment in the study and nurse survey. Efficacy was evaluated through anxiety, as measured by heart rate, respiratory rate, and patient/nurse survey; DTW; and patient/nurse satisfaction. Nurse surveys reported that MT was successfully incorporated into the milieu and 61 subjects were enrolled. Significant differences in heart rate and respiratory rate were found from the beginning to the end of MT sessions (p \u3c .05 and p \u3c .0001, respectively), indicating a more relaxed state. No significant difference in mean DTW was found between study and control subjects. Patient/nurse satisfaction was high. Music therapy can be used successfully to treat anxiety associated with weaning from mechanical ventilation. Limitations and suggestions for further research are discussed

Feasibility and Acceptability of Bright IDEAS-Young Adults: A Problem-Solving Skills Training Intervention

Background: Young adults with cancer are a vulnerable group with unique emotional, social, and practical needs. There is a lack of evidence-based interventions to address their needs and to foster skills that could increase their capacity to cope. Bright IDEAS is a problem-solving skills training intervention that has demonstrated efficacy in improving people’s problem-solving ability and reducing distress among caregivers of children with cancer. This study evaluated the feasibility and acceptability of Bright IDEAS adapted for young adults (Bright IDEAS-YA). Methods: Forty young adults recently diagnosed with cancer were enrolled in a single arm feasibility study. Results: Feasibility was demonstrated by the adequate enrollment (67.8%), retention (80.0%), and participants’ adherence to the intervention (average of 5.2 out of 6 sessions completed). Participants reported satisfaction with the intervention. Qualitative feedback identified the systematic approach to problem-solving and interaction with the trainer as strengths of the intervention. Participants demonstrated improvements in problem-solving skills and symptoms of depression and anxiety. Conclusions: In conclusion, the results support the feasibility of the intervention and an adequately powered randomized controlled trial is needed to determine the efficacy of the intervention on psychosocial outcomes

Peri-transplant psychosocial factors and neutrophil recovery following hematopoietic stem cell transplantation.

Multiple psychosocial factors appear to affect cancer progression in various populations; however, research investigating the relationship between psychosocial factors and outcomes following hematopoietic stem cell transplantation (HCT) is scarce. Subject to adverse immunological and psychological conditions, HCT patients may be especially vulnerable to psychosomatic health sequelae; therefore, we studied whether optimism and anxiety influence the pertinent clinical outcome of days to neutrophil engraftment (DTE).54 adults undergoing either autologous or allogeneic HCT completed self-report questionnaires measuring optimism and anxiety. We assessed the association between these psychosocial variables and DTE.Greater optimism and less anxiety were associated with the favorable outcome of fewer DTE in autologous HCT recipients, though this relationship was no longer significant when reducing the sample size to only subjects who filled out their baseline survey by the time of engraftment.Our findings are suggestive that optimism and anxiety may be associated with time to neutrophil recovery in autologous, but not allogeneic, adult HCT recipients. Further investigation in larger, more homogeneous subjects with consistent baseline sampling is warranted
