The efficiency of Governmental and WFP UN Programs for improvement of nutritional status in Tajik schoolchildren as assessed by dietary intake and hair trace element content.

BACKGROUND: The objective of the study was to assess hair trace element and mineral content in children undergoing WFP UN and the governmental programs of school nutrition in Tajikistan. METHODS: WFP program included provision or wheat flour fortified with micronutrients including Fe and Zn, and iodized salt, whereas within the governmental program hot meals were provided. A total of 202 children studying in schools that were not (Type 1, n = 100) or were involved in dietary intervention programs (Type 2, n = 102). Food and hair trace element content was assessed using ICP-MS. RESULTS: Daily intake of Fe, I, Zn, B, Co, Mg, Si, and Sr in Type 2 schools was more than 2.5, 12, 4, 2.9, 2.6, 2, 3, and 2-fold higher than that in Type 1 schools. Correspondingly, anthropometric parameters in children from Type 2 schools exceeded the control values. Surprisingly, no significant difference in hair iodine levels was detected. Hair analysis demonstrated a significant increase in hair Ca, Mg, Na, Co, Cr, Cu, Fe, Li, Mn, Se, V, Zn content. Certain toxic elements including Al, As, and Be were also characterized by an increase in Type 2 schools. At the same time, nutritional intervention was associated with a significant decrease in hair B, Hg, and Sn levels. CONCLUSIONS: Nutritional intervention within WFP and the governmental program was effective in increasing essential trace element supply in Tajik schoolchildren. However, further studies including a detailed assessment of nutritional and health status with a special focus on iodine and thyroid functioning are required.

EPOCH-F: a novel salvage regimen for multiple myeloma before reduced-intensity allogeneic hematopoietic SCT.

There exists a need for effective salvage regimens for multiple myeloma patients being considered for reduced-intensity allogeneic hematopoietic SCT (RI-alloHSCT). We developed EPOCH-F, a regimen consisting of infusional etoposide, VCR and adriamycin with prednisone, CY and fludarabine to achieve both tumor control and host lymphocyte depletion to facilitate engraftment before RI-alloHSCT. In all, 22 multiple myeloma patients were treated with EPOCH-F before RI-alloHSCT. The median age was 53 years (range 36-65), and the median number of previous therapies was 2 (range 1-8). Patients received a median of three cycles (range 1-5) of EPOCH-F. Toxicities were primarily hematologic and manageable. Median lymphocyte counts decreased from 1423/µL (range 335-2788) to 519/µL (range 102-1420; P=0.0002). The overall response (≥PR) to EPOCH-F was 22 with 13% achieving a CR/near-complete response (nCR); only 1 patient progressed while on therapy. A total of 20 patients underwent RI-alloHSCT. Median day +100 donor chimerism was 100% (range 60-100). In all, 70% of patients achieved very good partial response or better response after transplant; 40% of patients achieved CR/nCR. TRM at 100 days and 5 years was 5 and 30%, respectively. Median OS after RI-alloHSCT was 46.1 months. EPOCH-F provides disease control and host lymphocyte depletion with consistent full donor engraftment in multiple myeloma patients undergoing RI-alloHSCT.
