The influence of perinatal and maternal factors on physical growth at 12 months in prematurely born infants treated in the neonatal intensive care unit: A retrospective chart review and a prospective cohort study.

Background: Growth retardation during the first year of life is frequently observed in prematurely born infants. Few reports have considered the effects of maternal emotional distress and perceptions of care burden on the outcomes of these infants.

Objectives: This study investigated the physical growth trajectories of prematurely born infants treated in neonatal intensive care unit and determined the effects of perinatal factors, maternal emotional distress and perceptions of care burden on growth retardation at 12 months' corrected age.

High rate of unintended pregnancy among pregnant women in a maternity hospital in Córdoba, Argentina: a pilot study.

Background: Although Argentina has a new law on Reproductive Health, many barriers continue to exist regarding provision of contraceptive methods at public healthcare facilities.

Methods: We asked 212 pregnant women selected at random at the Maternity and Neonatal Hospital, Córdoba, Argentina, to participate in our descriptive study. Women were asked to complete a structured questionnaire.

[A retrospective analysis on multiple cord blood transplantation in 13 cases].

In order to study the feasibility of multi-umbilical cord blood transplantation (multi-UCBT) in adult, 13 cases of unrelated allogeneic multi-UCBT performed from June 1998 to July 2003 were analyzed retrospectively. All cord blood units were obtained from full term normal vaginal and cesarean deliveries in Guangzhou Maternity and Neonatal Hospital. The fractionation, cryopreservation and thawing of cord blood were done according to the regulation of New York Umbilical Cord Blood Bank and pertinent literatures.

[Effect of numbers of CD34+CD62L+ cells infused on unrelated umbilical cord blood transplantation in children with acute leukemia].

Objective: Several studies have shown that L-selectin on CD34-positive cells play a role in hematopoietic reconstitution after peripheral blood stem cell transplantation and allograft bone marrow transplantation. This study sought to investigate whether the numbers of CD(34)(+)CD(62L)(+) cells infused affect the engraftment of hematopoietic stem cells (HSC) and the time to neutrophil and platelet recovery after unrelated umbilical cord blood transplantation for the treatment of childhood acute leukemia.

Methods: Twenty-three children with acute leukemia who received unrelated umbilical cord blood transplantation of mostly mismatched HLA locus were included in this study.
