Microbiome dysbiosis has been associated with adverse outcomes of hematopoietic cell transplantation (HCT). We hypothesized that exposure to high-dose melphalan and antimicrobials in patients undergoing autologous HCT for plasma cell disorders results in oral and gastrointestinal microbial dysbiosis, which in turn is associated with regimen-related toxicities. We conducted a prospective study describing the longitudinal changes in oral and gastrointestinal bacteriome and mycobiome in this patient population. Our findings show that microbiome composition present at baseline is associated with the incidence and severity of post-transplantation nausea, vomiting, and culture-negative neutropenic fever, as well as with the rate of neutrophil engraftment. We also have evidence of an association between the microbial communities at count nadir and the development of regimen-related gastrointestinal toxicities commonly observed after exposure to high-dose melphalan. Although bacteriome diversity largely recovers within 1 month after transplantation, we observed a continuous decrease in oral and gastrointestinal mycobiome diversity, suggesting that the mycobiome requires a longer time to recover compared with the bacteriome.

When oncology nurses have strong communication skills, they play a pivotal role in influencing patient satisfaction, adherence to plans of care, and overall clinical outcomes. However, research studies indicate that nurses tend to keep communication with patients and families at a superficial, nontherapeutic level. Processes for teaching goals-of-care communication skills and for implementing skills into clinical practice are not clearly defined. Nurses at a large comprehensive cancer center recognized the need for help with this skill set and sought out communication experts to assist in providing the needed education. An educational project was developed to improve therapeutic communication skills in oncology nurses during goals-of-care discussions and giving bad news. The program was tailored to nurses and social workers providing care to patients in a busy, urban, academic, outpatient oncology setting. Program topics included exploring the patient's world, eliciting hopes and concerns, and dealing with conflict about goals. Sharing and discussing specific difficult questions and scenarios were encouraged throughout the program. The program was well attended and well received by oncology nurses and social workers. Participants expressed interest in the continuation of communication programs to further enhance skills.
