Spiritual practices are associated with improved weight management following bariatric surgery.

BACKGROUND: Research shows that spirituality and religiosity may positively impact various health outcomes, but little is known about their role in supporting weight management efforts, particularly in the context of bariatric surgery. OBJECTIVE: This study examined spiritual practices and health-related behaviors of bariatric surgery patients 1-2 years postoperatively. SETTING: Large bariatric center in the Midwest of the United States. METHODS: Patients (n = 152) completed questionnaires 1-2 years postoperatively examining weight, physical activity, eating behaviors, and spiritual practices and experiences related to bariatric surgery. RESULTS: Participants were primarily married (59.2%), Caucasian (81.6%), and female (84.2%) who had undergone Roux-en-Y gastric bypass (64.5%) or sleeve gastrectomy (32.9%) 17.3 months previously. Most participants (71%) believed their spirituality did or could impact weight loss after surgery. Practices including connecting with nature, art and music, meditation, yoga, and attending spiritual or religious-based activities were positively correlated with weight loss, healthy eating, or exercise participation. CONCLUSION: Findings provide preliminary evidence for the benefits of spirituality in bariatric patients making lifestyle changes after surgery.

Effect of Donor Age and Donor Relatedness on Time to Allogeneic Hematopoietic Cell Transplantation in Acute Leukemia.

Relapse after allogeneic hematopoietic cell transplantation (HCT) for acute leukemia can be reduced when pursued early after first complete remission. The impact of donor age and donor relatedness on the time from diagnosis to transplant in patients with acute leukemia was examined to clarify the design of future prospective studies that can address optimal donor choice. Files of 100 consecutive patients undergoing transplantation for leukemia were reviewed. Recipients of related donors (RDs) and unrelated donors (UDs) were not significantly different in terms of recipient gender, age, underlying diagnosis, disease risk index, graft source, or donor HLA match. UDs were significantly younger than RDs (median age, 29 versus 51, P < .001). Multivariate linear regression revealed that when controlling for age of donor and recipient, the time from diagnosis to transplant was 35% longer with UDs compared with RDs (P = .018). No significant correlation was observed between donor and recipient age on length of time to transplant (P = .134 and P = .850, respectively), when controlling for other variables. The steps in UD procurement that contribute most to the longer time to transplant relate to activating the donor workup and scheduling the donor workup before cell collection. Understanding sources of delay in the transplant process will help transplant centers and UD registries reduce the time to transplant for patients with acute leukemia and will provide necessary insight for the design of prospective controlled studies that can address optimal donor choice.

Biofilm-forming skin microflora bacteria are resistant to the bactericidal action of disinfectants used during blood donation.

BACKGROUND: A one-step skin disinfection method containing 2% chlorhexidine-gluconate (CHG) and 70% isopropyl alcohol (IPA) is currently used by blood suppliers worldwide. Reports of bacterially contaminated platelet concentrates (PCs) indicate that skin disinfection is not fully effective. Approximately 20% of skin microflora exist as surface-attached aggregates (biofilms), known for displaying increased resistance to disinfectants. This study was aimed at determining whether skin microflora biofilm-positive Staphylococcus epidermidis and Staphylococcus capitis are resistant to CHG and/or IPA. STUDY DESIGN AND METHODS: Free-floating cells and mono or dual (1 : 1 ratio) biofilms of S. epidermidis and S. capitis were exposed to CHG, IPA, or CHG/IPA for 30 seconds, simulating skin disinfection practices. Residual viable cells were quantified by colony counting. Morphology of disinfectant-treated S. epidermidis biofilms was examined by scanning electron microscopy. Treated S. epidermidis and S. capitis biofilms were inoculated into PCs and bacterial concentrations were determined on Days 0 and 5 of storage. RESULTS: Treatment of staphylococcal biofilm cells with all disinfectants caused cell damage and significant reduction in viability, with CHG/IPA being the most effective. However, biofilms were significantly more resistant to treatment than free-floating cells. Disinfectant-treated S. epidermidis proliferated better in PCs than S. capitis, especially when grown as monospecies biofilms. CONCLUSION: Although CHG/IPA is effective in reducing the viability of S. epidermidis and S. capitis biofilms, these organisms are not completely eliminated. Furthermore, disinfectant-treated staphylococcal biofilms multiply well in PCs. These results demonstrate that the biofilm-forming capability of the skin microflora reduces the bactericidal efficiency of blood donor skin disinfectants.
