The updated centile charts in this study may be used as reference charts for the birth weight, length and head circumference for the local population. Using earlier growth charts or the Western charts would misclassify the infants at birth into SGA or LGA.
We present a theoretical analysis of the noise behavior of a heterojunction bipolar transistor (HBT) used as a three terminal (3T) photodetector. The use of a HBT in the photodetector mode can greatly simplify the fabrication of HBT-based optical receivers in the monolithic form. The present model takes into account the effect of the received light on the intrinsic parameters and various noise components of the HBT when used as a detector. The model enables one to determine the signal-to-noise ratio at the output and also the noise equivalent power of the HBT. The model has been applied for characterization of an InP/ InGaAs HBT used as a 3T photodetector in the 1.55-m wavelength region.
The study analyses maternal and fetal complication in the GDM group and also preexisting diabetes group. In our centre, the 60 % women were GDM while 40 % were having pre-existing diabetes. Total rate of fetal/neonatal complication rate was 7.69 % and of congenital anomaly rate it was 9.23 %. Proportion of still birth, Intrauterine death, and congenital malformations was higher in the pre-existing diabetes group although the data are not large enough to draw a statistically significant conclusion. LSCS rate was little higher in the GDM group (69.23 %) in comparison to the preexisting diabetes group where it was 57.69 %. SVD (Spontaneous Vaginal Delivery) rate was 30.77 % in GDM and 42.31 % in the pre-existing diabetes group. HbA1c was within normal range 84.62 % of GDM group while in 15.38 % it was raised >6 %. In the pre-existing diabetes group, only 19.23 % of women had HbA1c within acceptable range and 80.77 % had it >6. The aim of St Vincent Declaration is to 'achieve pregnancy outcome in the diabetic woman that is similar to that of the non-diabetic woman.' But, so far we have not been able to achieve this. Our HbA1c level is remarkably high in the pre-existing diabetes group. Only 3 out of 65 patients' women took Folic Acid periconceptionally. We need to work to achieve it our best. It is well known that insulin treatment during pregnancy results in reduction in the rate of macrosomia, fetal/neonatal, and maternal complications. Therefore, we need to use insulin judiciously and advocate its usage in the situations where it is needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
