Comparative study of low dose aspirin versus combination of low dose aspirin and low molecular weight heparin in idiopathic recurrent pregnancy loss

Background: To compare the role of low dose aspirin versus combination of low dose aspirin and low molecular weight heparin in idiopathic recurrent pregnancy loss and assess the effectiveness of low dose aspirin and low molecular weight heparin in having a better obstetric outcome.Methods: This study was conducted in a private hospital in Mahabubnagar from June 2017 to May 2019. A total of 80 pregnant ladies who had previous 2 and or more pregnancy losses in the early (before 20 weeks) or late (after 20 weeks) pregnancy period was included in the study. 80 pregnant women with idiopathic/unexplained recurrent pregnancy loss were properly evaluated in regard to the history of previous period of gestation of loss, previous scans in regard to documentation of fetal pole and gestation, cardiac activity, anomaly scan and growth scan and any special investigations in previous pregnancies and present pregnancy.Results: A total 80 pregnant women with previous 2 and more unexplained pregnancy losses who were evaluated and found negative with major causes of pregnancy losses half of them (40) were treated with low dose aspirin alone and the other 40 women were treated with a combination of low dose aspirin (75 mg) and low molecular weight Heparin (20 mg) daily low molecular weight heparin till term. The aspirin alone group had 82.5% live birth rate and the combination group had 92.5% live birth rate which is quite satisfactory and more than the Aspirin alone group.Conclusions: Use of combination of low dose aspirin and low molecular weight heparin seems to be a good choice of drugs in treating the unexplained recurrent pregnancy losses than low dose aspirin alone.

Early hospital discharge and readmission jaundice in term babies

Background: Hyperbilirubinemia is a common and often benign disease in the neonatal period. It is the most common cause of readmission in early neonatal period. Prolonged hyperbilirubinemia can result in chronic bilirubin encephalopathy. Increasing the hospital stay of otherwise healthy neonates is not an acceptable solution for medical, social and economic constraints. So, identifying the risk factors for readmission assumes importance. Aim of our study is to identify the risk factors for readmission jaundice in our hospital.Methods: In this study, authors used a questionnaire to find out the risk factors for readmission in those babies who were readmitted with jaundice within 3 weeks of life to our hospital. During the study period, routine treatment practices were followed and there was no deviation from the standard of care for the purpose of research.Results: Of the 2297 deliveries during this study period, 93 babies (4%) were readmitted with jaundice.Among the 93 babies, prevalence of blood group incompatibility was one of the common causes of neonatal jaundice. 46.2% of the babies had an early discharge. Total Serum bilirubin levels were measured by a hospital-based bilirubin assay. Babies with serum bilirubin level above photozones as per American Academy of Pediatrics practice guidelines 2004 were identified and subjected to photo therapy. All the babies in this study responded to photo therapy. No other interventions were needed.Conclusions: Though an early discharge is the most cost-effective strategy in this era of high medical expenditure, we can identify certain high-risk babies, prone for readmission. Blood group incompatibility, infants of primiparous mothers and GDM mothers are more prone to readmission jaundice. Identifying these high-risk babies and educating the mothers is a more cost-effective strategy than prolonging the hospital stay for all babies.

Response surface methodology for optimization of production of lovastatin by solid state fermentation

Lovastatin, an inhibitor of HMG-CoA reductase, was produced by solid state fermentation (SSF) using a strain of Aspergillus terreus UV 1718. Different solid substrates and various combinations thereof were evaluated for lovastatin production. Wheat bran supported the maximum production (1458 ± 46 µg g-1 DFM) of lovastatin. Response surface methodology (RSM) was applied to optimize the medium constituents. A 2(4) full-factorial central composite design (CCD) was chosen to explain the combined effects of the four medium constituents, viz. moisture content, particle size of the substrate, di-potassium hydrogen phosphate and trace ion solution concentration. Maximum lovastatin production of 2969 µg g-1 DFM was predicted by the quadratic model which was verified experimentally to be 3004 ± 25 µg g-1 DFM. Further RSM optimized medium supplemented with mycological, peptone supported highest yield of 3723.4±49 µg g-1 DFM. Yield of lovastatin increased 2.6 fold as with compared to un-optimized media.

Retinopathy of prematurity: incidence and risk factors.

OBJECTIVE: To determine the incidence of Retinopathy of Prematurity (ROP) in high risk babies admitted to the neonatal unit and to study risk factors for it's development. DESIGN: Prospective cohort study. SETTING: Level II Neonatal Intensive Care Unit. SUBJECTS: 100 babies admitted to the neonatal unit during a 4 year period who were below 1500 g or whose gestation was < or = 34 weeks. METHODS: Examination of the eye was done in the neonatal unit or in the neonatal follow up clinic by an Ophthalmologist by indirect Ophthalmoscopy at 4-6 weeks postnatal age. RESULTS: The incidence of ROP was 46%. Of the 100 babies screened, 21 had stage I, 14 had stage II, 8 had stage III and 3 had stages IV and V. The incidence of ROP was 73.3% among < 1000 g babies and 47.3% among < 1500 g babies. The incidence of ROP among 28-29 weeks, 30-31 weeks and 32-33 weeks babies was 83%, 60% and 50%, respectively. The maximum stage of ROP developed between 37-42 weeks post conceptional age in 69% subjects. On univariate analysis, gestation < or = 32 weeks, anemia, Blood transfusions, apnea and exposure to oxygen significantly increased the risk of developing ROP. On multivariate logistic regression analysis, anemia and duration of oxygen therapy were the significant independent predictors of development of ROP. Nine of the 46 babies underwent cryotherapy for threshold ROP. CONCLUSION: The incidence of ROP among high risk babies is significant and duration of oxygen therapy and anemia are independent factors predicting the development of ROP. All high risk babies should be screened for ROP. Cryotherapy is a relatively simple procedure which can be done in the neonatal unit.

Comparison of rectal and axillary temperatures in neonates admitted to a neonatal unit.

To determine whether axillary temperature could be used as an alternative to rectal temperature, 45 neonates were subjected to simultaneous rectal temperature and axillary temperature recordings. Each baby had an average of 10 recordings over the first 72 hours. The mean of these readings was taken and subjected to regression analysis and the 't' paired test. The overall mean difference between the rectal and axillary temperature was 0.3 degrees F. The mean difference was least in preterm small for date (SFD) babies (0.2 degrees F) and most in preterm appropriate for date (AFD) babies (0.5 degrees F). The mean difference was less in incubator babies (0.2 degrees F) compared to those in warmer cradles (0.4 degrees F). The regression analysis showed that the correlation was good in all groups except the term small for date babies. We conclude that axillary temperature could be used as an alternative to rectal temperature in neonates.
