Comparative Study
Genetic structure of three Native Mexican communities based on mtDNA haplogroups, and ABO and Rh blood group systems.
The goals of this population genetics study were to describe mtDNA haplogroups and ABO and Rh blood group systems of 3 Native Mexican populations, to determine their genetic variability, and to compare their haplogroups with those of 13 Native Mexican populations previously reported. ⋯ Regarding the blood groups, the O group was the most frequent in the three populations (97.2, 94.7, and 86.2%, respectively), as well as the Rh+ group (100, 100, 84%). The three populations analyzed were in Hardy-Weinberg equilibrium. In respect to the mtDNA haplogroups, A, B, C and D, their percentage was 33.3, 36.1, 13.9 and 5.6 % in Huehuetla; 39.5, 13.2, 39.5 and 2.6 % in San Antonio el Grande, and 55.3, 21.0, 7.9 and 5.2 % in Juchitán. Between 5 and 11% of the haplogroups were of non-Amerindian origin, probably due to admixture with Caucasian and African populations, as has been reported in the past. No statistically-significant differences were found among the three populations studied or between them and 13 previously reported Native Mexican populations.

Comparative Study
[Associated factors to extubation failure in the term newborns from a neonatal intensive care unit].
The mechanical ventilator support (MVS) it is a procedure which improves survival of critically ill newborns (NB), but is not risk free one of them is tracheal damage reintubations by extubation failure. Knowledge that there is the medical literature is about preterm infant and there is not information about term NB. ⋯ Based on the above we conclude that in the term NB with MVS before placing in tracheal CPAP for the extubation should have a PIP < or = 18 cm H2O, cycles < or = 15x' and a hemoglobin not smaller than 13 g/dL to avoid this way as much as possible the extubation failure and with it to improve the prognosis.

This article reports the experience of the largest pediatric liver transplant (LT) program in México. Between June 1998 and May 2011, 76 LT were performed in 74 recipients, including 80% cadaveric-whole organ grafts and 20% segmental grafts, 12% of those coming from live donors and 8% from cadaver reduced donors. The most common indication for LT was biliary atresia (43%), followed by metabolic disorders (13%) and fulminant hepatitis (12%). ⋯ The first successful live donor LT in the country was performed in 2001 at this program, as was the first simultaneous liver-kidney transplant in a child. This is the largest and most successful pediatric LT series in the country. Our results demonstrate that pediatric LT is a feasible undertaking in Mexico, with survival rates similar to those of foreign centers.
