Abstract The primary objective of this work was to determine the feasibility of a randomized trial of individualized yoga for children receiving intensive chemotherapy and for hematopoietic stem cell transplantation (HSCT) recipients outside of the principal coordinating institution. We evaluated the feasibility of a randomized trial of individualized yoga versus an iPad control program at a site where external yoga instructors were hired and compensated per session. Subjects were children receiving intensive chemotherapy for hematological malignancies and autologous or allogeneic HSCT recipients expected to be hospitalized for 3 weeks. Yoga or iPad control contact occurred daily for 21 days (excluding weekends and holidays); fatigue and quality-of-life outcomes were measured at baseline, day 10, and day 21. Ten eligible subjects were identified; six subjects consented and were enrolled. Three were randomized to the individualized yoga intervention and three to the iPad control program. The median age of participants was 12 (range 8–15) years, and 2 (33%) were boys. Challenges primarily related to the hiring of yoga instructors who were not trained in research methods. We found issues with: (1) logistics of hiring, training, and retaining instructors; (2) communication between teams; (3) fidelity to the protocol and outcome assessments; and (4) ensuring safety. We found that a randomized trial of individualized yoga presented new challenges when relying on externally contracted yoga instructors. Future multicenter studies of yoga should seek to better integrate practitioners within the research team to improve processes, communication, fidelity to the protocol, and safety.

Abstract Background Invasive fungal infections (IFI) remain a serious complication in hematopoietic stem cell transplantation (HSCT) patients and are associated with increased costs, morbidity, and mortality. Posaconazole (PCZ) and voriconazole (VCZ) are frequently utilized as antifungal prophylaxis in this population. To date, no direct comparison between PCZ and VCZ exists for the prevention of IFI in adult HSCT patients. Methods A retrospective cohort analysis of HSCT patients aged ≥18 years who received ≥28 continuous days of primary (PPPx) or secondary (SPPx) antifungal prophylaxis with either VCZ or PCZ between February 26, 2003 and September 30, 2015 at Barnes-Jewish Hospital was conducted. Patients who received PPPx or SPPx with both VCZ and PCZ were analyzed following intention to treat of the initial agent received. Patients who received both PPPx and SPPx were included once for both PPPx and SPPx. The primary outcome of interest was development of possible, probable, or proven IFI as defined by EORTC/MSG guidelines. In the SPPx patients, development of IFI was confirmed as a distinct event from primary IFI based on manual chart review and radiographic evidence. Results Overall, there were 472 patients included; 402 in the VCZ group and 70 in the PCZ group. At baseline, patients in the PCZ group had more graft vs. host disease (GVHD) prior to prophylaxis (27.1% vs. 16.7%, P = 0.04) and were more likely to be on SPPx (60% vs. 41%, P < 0.01). There were 22 and 1 IFI events in the VCZ and PCZ groups, respectively, which corresponded to a crude incidence rate of 0.345 and 0.077 per 1000 person-days of prophylaxis. Figure 1 displays the Cox proportional hazard model which was completed in the backwards stepwise method accounting for gender, transplant type, GVHD prior to prophylaxis, disease remission, and PPPx or SPPX. The hazard ratio for development of IFI while on prophylaxis between VCZ and PCZ was 5.22 (95% CI: 0.69–39.4; P = 0.11) after controlling for PPPx or SPPx. Conclusion There was not a significant difference between rates of IFI in HSCT patients who received antifungal prophylaxis with VCZ compared with PCZ. Our data trends towards favoring PCZ but is limited by low rates of IFI. Larger, prospective analyses are necessary to confirm our findings.
