Research: Pre-eclampsia is a disease with signs of hypertension, edema, and proteinuria arising from pregnancy. This disease generally occurs in the third trimester of pregnancy, but can occur earlier, for example in hydatidiform mole (Wiknjosastro, 2005: 282). Preeclampsia and Eclampsia are one of the main causes of maternal mortality in Indonesia. The incidence of preeclampsia ranges from 5-15% of all pregnancies in the world. Based on the 2003 Indonesian Demographic and Health Survey (IDHS), the incidence of preeclampsia in Indonesia is estimated at 3.4–8.5%. The research method used analytical observational method through a case control approach, which is an analytical study concerning how risk factors are studied using a retrospective approach. In other words, the effect is identified now, then the risk factor is identified as having existed or occurred in the past. Research Results The results of the significance test using the Chi-Square test showed a significant relationship to the occurrence of low birth weight (LBW) in mothers with preeclampsia. This is indicated by the value of p = 0.000 which is smaller than α = 0.05, so Ho is rejected. While the results of the calculation of the Odds Ratio show that preeclampsia is one of the causes of LBW, this is indicated by the OR value of 3.028. Conclusion: There is a relationship between preeclampsia and low birth weight in dr. Soedarso Pontianak in 2018 with a probability value (ρ) = 0.000.

Selection Indexes

More recently, swine breeding programs have aimed to include pork quality and novel carcass (e.g., specific primal cuts such as the Boston butt or belly that are not commonly used in selection indexes) and belly traits together with growth, feed efficiency and carcass leanness in the selection indexes of terminal-sire lines, in order to efficiently produce pork with improved quality at a low cost to consumers. In this context, the success of genetic selection for such traits relies on accurate estimates of heritabilities and genetic correlations between traits. The objective of this study was to estimate genetic parameters for 39 traits in Duroc pigs (three growth, eight conventional carcass (commonly measured production traits; e.g., backfat depth), 10 pork quality and 18 novel carcass traits). Phenotypic measurements were collected on 2583 purebred Duroc gilts, and the variance components were estimated using both univariate and bivariate models and REML procedures. Moderate to high heritability estimates were found for most traits, while genetic correlations tended to be low to moderate overall. Moderate to high genetic correlations were found between growth, primal-cuts and novel carcass traits, while low to moderate correlations were found between pork quality and growth and carcass traits. Some genetic antagonisms were observed, but they are of low to moderate magnitude. This indicates that genetic progress can be achieved for all traits when using an adequate selection index.

Number Of Factors

A desirable liveweight for red deer at 15 months of age is approximately 80 kg. This will provide a saleable carcase and a liveweight at which yearling hinds will successfully breed. Live-weight at 15 months will be influenced by a large number of factors including date of birth, birth-weight, liveweight gain to weaning, date of weaning, liveweight gain during the first winter and subsequent summer, and the interactions between weaning weight and subsequent levels of nutrition and between winter levels of nutrition and liveweight gain at pasture in the following summer. These latter two aspects were examined in two experiments and the effect of date of weaning on contemporary calf growth rates and on hind calving date in the following year were studied in a third experiment. The objective was to provide information which would allow the development of effective systems of deer meat production based on slaughter at 15 months of age.

Data from a swine breed development project provided estimates of the genetic correlation among six performance and carcass traits. The data from the new breed, called Managra, were obtained over a 7-year period. Most genetic relationships examined were such that selection for improvement of one trait would yield a favorable improvement in another. Both carcass backfat and live backfat probe were found to be negatively correlated with area of loin eye and length of carcass. A positive genetic correlation was found between post-weaning daily gain and loin eye area. A high positive genetic correlation was found between birth weight and loin eye area. An unfavorable association involved a positive genetic correlation between birth weight and backfat.Correction factors for effect of carcass weight on the magnitude of carcass trait measurements and differences in means between sexes were obtained.Heritability of the traits was estimated by paternal half-sib correlation. The estimates for carcass traits were moderately high and agree well with most other estimates reported in the literature.

The aim of present study was to assess the effect of the gender on growth and carcass traits in lambs of the Romney Marsh breed. The experimental animals were male lambs (n = 12) and female lambs (n = 12) of the Romney Marsh breed. All lambs were twins and all their mothers were on the second parity. With regard to body weights and daily gains (DGs), the gender had a significant effect only on birth weight and DG from birth to the slaughter, while in all monitored intervals the DGs were higher in male lambs (MLs). The lamb gender did not have a significant effect on the easy of lambing, body condition score, depth of musculus longissimus lumborum et thoracis (DMLLT) and thickness of backfat (TBF). However, values for DMLLT and TBF were higher in female lambs (FLs), which in case of DMLLT was not expected. Regarding the carcass traits, the gender had a significant effect only on the weights of kidney, kidney fat, leg and shoulder and on the proportions of kidney fat and shoulder. Interestingly, the gender had no significant effect on the conformation and fatness, while slightly better carcass conformation and slightly higher fatness were found in FLs. It can be concluded that FLs of the Romney Marsh breed showed comparable values for both the growth and carcass traits with MLs. Moreover, a slightly higher fatness of FLs is a prerequisite for better juiciness and tenderness of their meat, when this fact can be considered as a benefit in the marketing.

Objective: The objective of the study was to measure the proportion of GDM in antenatal outdoor of a hospital, to find out the mean gestational period at which most delivery occurred in GDM and to assess the perinatal outcome.Study design : It was a prospective analytical study conducted in BSMMU, from March,2010 to February,2011.Method: 1489 pregnant women, not known to be diabetic previously, were selected by consecutive sampling in first trimester from Obstetrics outdoor, BSMMU. Their FBS and blood glucose 2hrs after 75gm oral glucose were recorded. We investigated blood glucose in first, second and third trimester in the same pregnant women for screening GDM. Cut off GDM values in fasting stage was e” 6.1mmol/l and 2 hrs after 75gm oral glucose was e” 7.8mmol/l .Result: The proportion of GDM in Obstetrics Outdoor of BSMMU was 6.85%. The mean gestational period at which delivery occurred was lower in GDM ( 36.9 ± 2.2 wks ) than that in non-GDM (39 ± 1.6 wks ) .The most common (31.4%) gestational week during delivery in GDM was 37 completed weeks. Birth weight of 40.2% babies were in the range of 2.5kg to 3.0kg, 31.4% in the range of 3.1 to 3.5 kg and 1% neonate died after birth in GDM.Conclusion: Presently GDM is diagnosed early. The mean gestational period at delivery in GDM is 36.9±2.2 wks. Majority neonatal birth weight is of normal range. Neonatal mortality rate is not increased and is not significantly different from non-GDM women.J Bangladesh Coll Phys Surg 2015; 33(2): 79-85

Study Setting

Objectives: LBW has long been labeled as one of the major risk factor for mortality as well as morbidity in neonates. South Asia is said to have highest number of LBWs which estimated to be 1 in 4 newborns that weigh < 2500 grams. This study was planned with an aim to note the burden, types of diseases and outcome in LBW newborns admitted at a tertiary care hospital. Study Design: Descriptive analytical study. Setting: Included all neonates admitted to NICU of Sheikh khalifa Bin Zaid Al Nahyan Teaching Hospital, Rawlakot. Period: 1st July 2018 to 31st December 2018. Material & Methods: The prevalence of LBW amongst all admissions was calculated along with demographic features of all LBW babies like disease, reasons for the admission, duration of hospital stay along with outcome was noted on a predesigned proforma. Results: Out of total of 1410 admission in NICU during the study period, 512 (36.3%) were noted to be LBW. Amongst LBW babies, mean weight was 1.91 kg while 269 (52.5%) were male and 243 (47.5%) female. There were 364 (67.6%) babies born at full term. There were 82 (16.0%) with birth weight of less than 1.5 kg, 166 (32.4%) between 1.5 to 2 kg while 264 (51.6%) were above 2 kg. Amongst all LBW babies, mortality was reported in 185 (36.1%) while 112 (60.5%) died on the 1st day of admission. Respiratory distress syndrome (31.4%), sepsis (20.3%) and neonatal jaundice 58 (11.3%) were the commonest diseases seen. Highest mortality (56.1%) was seen in babies who had birth weight below 1.5 kg (p value = 0.001). Conclusion: LBW is a major cause of hospitalization and mortality. RDS and sepsis were the most frequent diseases noted in LBW babies. Immediate care following birth is vital for babies already at risk of LBW.
