121. Assessment of different folic acid supplementation doses for low-birth-weight infants (PubMed)

Assessment of different folic acid supplementation doses for low-birth-weight infants The adequacy of 50 mcg folic acid supplementation given to low-birth-weight babies was investigated. The folate levels of the mothers and infants, and breastmilk, and the optimum dose for folic acid supplementation were also investigated.After obtaining blood from 141 low-birth-weight infants on the 1st day of life for serum and red cell folate levels, the infants were randomly allocated into three groups (...) postnatally. The feeding modes of the infants, maternal folic acid intake, and details of neonate intensive care unit course were recorded.The mean birth weight and gestational age of the infants were found as 1788.2±478.4 g and 33.5±2.9 weeks, respectively. The mean serum and red cell folate levels on admission were found as 21.2±12.2 ng/mL and 922.7±460.7 ng/mL, respectively. The mean maternal serum and red cell folate levels and the mean breast milk folate levels were found as 12.3±7.5 ng/mL, 845.5

122. Safety and efficacy of packed red blood cell transfusions at different doses in very low birth weight infants. (PubMed)

Safety and efficacy of packed red blood cell transfusions at different doses in very low birth weight infants. This double-blinded, randomized, crossover study evaluated the safety and effectiveness of 20 mL/kg aliquots of packed red blood cell (PRBC) transfusions versus 15 mL/kg aliquot transfusions in very low birth weight (VLBW) infants with anemia. The study enrolled 22 hemodynamically stable VLBW infants requiring PRBC transfusions, with a mean gestational age of 25.7 ± 2.2 weeks and birth (...) weight of 804 ± 261 g. Each infant was randomized to receive one of two treatment sequences: 15 mL/kg followed by 20 mL/kg or 20 mL/kg followed by 15 mL/kg. The infants were monitored during and after transfusions, and the efficacy and safety of the treatments were evaluated. Infants had higher posttransfusion hemoglobin (13.2 g/dL vs 11.8 g/dL, P < 0.01) and hematocrit levels (38.6 g/dL vs 34.4 g/dL, P < 0.01) following 20 mL/kg PRBC transfusions when compared to 15 mL/kg transfusions.

Weight Loss Analysis According to Different Formulas after Sleeve Gastrectomy With or Without Antral Preservation: a Randomised Study. The measurement of weight loss after bariatric surgery is under constant review in order to obtain the ideal standard for reporting weight loss. Several formulas have been proposed for this purpose. Our goal is to analyse weight loss after sleeve gastrectomy, with or without antrum preservation through different measurement formulas.A prospective randomised (...) study of 60 patients (30 patients with initial section at 3 cm from pylorus and 30 patients at 8 cm from the pylorus). We calculate the following variables at 3, 6 and 12 months from surgery: BMI, excess weight loss (%EWL), percentage of excess of BMI loss (%PEBMIL), expected BMI, % PEBMIL corrected by EBMI and percentage of total weight loss (%TWL).Weight evolution is similar in both groups, reaching a mean BMI of 33.62 ± 4.35 and 34.48 ± 4.23 kg/m2 respectively 12 months after surgery, closer
