  1. Relationship between head growth and neurodevelopmental outcome of Malaysian very low birthweight infants during the 1st year of life
    Ong LC, Boo NY, Chandran V, Zamratol SM, Allison L, Teoh SL, et al.
    Ann Trop Paediatr, 1997 Sep;17(3):209-16.
    PMID: 9425375
    A prospective study was carried out to (i) compare head growth patterns of 103 very low birthweight (VLBW, < 1500 g) Malaysian infants and 98 normal birthweight (NBW, 2500- < 4500 g) controls during the 1st year of life; and (ii) examine the relationship between neurodevelopmental outcome at 1 year of age and occipito-frontal head circumferences (OFC) at birth and at 1 year of age in VLBW babies. When compared with those of NBW infants at birth, mid-infancy and 1 year of age, the mean OFC ratios (observed/expected OFC at 50th percentile) of VLBW infants were significantly lower (p < 0.001). Small-for-gestational-age (SGA) VLBW babies had significantly lower mean OFC ratios than their appropriate-for-gestational-age (AGA) VLBW counterparts at birth (p < 0.001), but this difference was no longer seen at mid-infancy or at 1 year of age. Logistic regression analysis showed that abnormal late neonatal cranial ultrasound findings (odds ratio 8.5, 95% confidence interval 4.12-22.07; p < 0.001) and each additional day of oxygen therapy (odds ratio 1.15, 95% confidence interval 1.00-4.45; p = 0.045) were significant risk factors associated with neurodevelopmental disability at 1 year of age, while mean OFC ratios at birth or at 1 year of age were not. Poor postnatal head growth per se did not predict disability, but probably reflected the consequences of "brain injury" as evidenced by abnormal brain scans.

  3. Child health, breast-feeding, and survival in Malaysia: a random-effects logit approach
    Montgomery MR, Richards T, Braun HI
    J Am Stat Assoc, 1986 Jun;81(394):297-309.
    PMID: 12155406
    This study examines the possibility that estimation of the effect of breast-feeding on infant survival is affected by selection bias, in that children who are healthier at birth may be more likely to be breast-fed. Data are from the 1976 Malaysian Family Life Survey. "Ordinary logit models for breast-feeding and survival are estimated, and the results suggest that selection is indeed present. For example, children of higher birth weight appear to be more likely to be breast-fed and likely to survive. In addition, weight at birth and the duration of breast-feeding appear to be linked." Using birth weight as an indicator for the child's health, the authors conclude that "the direct influence of breast-feeding on survival remains of overwhelming importance even after corrections for selection bias are made."

    The relationship between zinc and infant birth weight is still contradictory and up until today there is still no research on this issue done in Iran. This unmatched case control study to evaluate the association between plasma cord blood zinc and infant birth weight at the time of delivery was carried out in the labor ward, Fatemieh Hospital, Hamadan, Iran from the 6 th December 2009 to 18 October 2010. Plasma venous cord blood zinc was measured by AtomicAbsorption Spectro-photometry (AAS) and the weight of 134 Low Birth Weight (LBW) infants (cases) and 134 normal
    weight infants (control) were measured at the time of delivery. All mothers with history of chronic diseases, obstetric complications, anemia, twin pregnancy, smoking, using illicit drugs, and alcohol and infants with any obvious anomalies were excluded from this study. Data were analyzed using SPSS version 16. Logistic regression was used to assess the contribution of other risk factors on infant birth weight. The result showed there was significant relationship between infant birth weight and plasma cord blood zinc. The risk of having LBW infant is more than 12 times in mothers who have severe zinc deficiency (OR=12.234,CI 95% 1.122, 133.392, p-value= 0.040). Also in mothers
    who have mild to moderate zinc deficiency the risk of having LBW was more than one (OR=1.148, CI 95% 0.358, 3.900, p-value= 0.797). A significant relationship between maternal pre-pregnancy Body Mass Index (BMI) (p< 0.002), maternal weight gain during pregnancy (p< 0.021), previous LBW (p< 0.016), maternal age (p< 0.034) and parity (p< 0.004) with infant birth weight were also found. Logistic regression showed that zinc deficiency along with maternal pre-pregnancy BMI, maternal weight gain during pregnancy, previous LBW, maternal age and parity were predictors
    for infant birth weight.

    Reprod Biomed Online, 2016 Aug;33(2):149-60.
    PMID: 27209497 DOI: 10.1016/j.rbmo.2016.04.014
    To examine the effect of cryopreservation on developmental potential of human embryos, this study compared quantitative β-HCG concentrations at pregnancy test after IVF-fresh embryo transfer (IVF-ET) with those arising after frozen embryo transfer (FET). It also tracked outcomes of singleton pregnancies resulting from single-embryo transfers that resulted in singleton live births (n = 869; with 417 derived from IVF-ET and 452 from FET). The initial serum β-HCG concentration indicating successful implantation was measured along with the birthweight of the ensuing infants. With testing at equivalent luteal phase lengths, the median pregnancy test β-HCG was significantly higher following FET compared with fresh IVF-ET (844.5 IU/l versus 369 IU/l; P < 0.001). Despite no significant difference in the average period of gestation (38 weeks 5 days for both groups), the mean birthweight of infants born following FET was significantly heavier by 161 g (3370 g versus 3209 g; P < 0.001). Furthermore, more infants exceeded 4000 g (P < 0.001) for FET although there was no significant difference for the macrosomic category (≥4500 g). We concluded that FET programme embryos lead to infants with equivalent (if not better) developmental potential compared with IVF-ET, demonstrated by higher pregnancy β-HCG concentrations and ensuing birthweights.

  13. Fulltext Amino acid dosing in parenteral nutrition for very low birth weight preterm neonates: an outcome assessment
    Kamarudin NA, Manan MM, Zulkifly HH, Neoh CF, Ali SM, Ming LC
    Asia Pac J Clin Nutr, 2016;25(1):53-61.
    PMID: 26965762 DOI: 10.6133/apjcn.2016.25.2.02
    This study aimed to investigate the effects of parenteral nutrition (PN) administration of amino acids (AA) on physical changes among very low birth weight infants in a local hospital setting in Malaysia. A retrospective study was carried out at a hospital in Malaysia. Records of neonates prescribed PN in the neonatal unit in 2012 were screened for eligibility. A total of 199 premature neonates received PN support in the year 2012 and, of these, 100 fulfilled the inclusion criteria. The median value of AA intake on the first day of PN was 2.00 (<28 weeks group); 1.00 (28-31 weeks group) and 0.75 (>31 weeks group). Neonates in the <28 weeks group were more likely to receive AA at an earlier time and higher initial dose compared with the other age groups. The study also found that there was no statistically significant difference in the dose of AA on the first day of PN administration and that the significant variations in nutritional parameters among the subjects did not lead to differences in physical outcomes. This study identified that when PN is provided in the local hospital setting, it is likely that the current nutritional practices are inadequate to achieve the standard growth recommendations. Our findings call for a need to optimize AA and calorie intake since growth restriction is a morbidity which will affect the infants' growth and development. Current prescriptions for PN in this hospital need to be reviewed in order to improve patient outcomes.

  14. Maternal height, and ethnicity and birth weight: A retrospective cohort study of uncomplicated term vaginal deliveries in Malaysia
    Teoh ZH, Mariapun J, Ko VSY, Dominic NA, Jeganathan R, Karalasingam SD, et al.
    Birth, 2024 Sep;51(3):620-628.
    PMID: 38475673 DOI: 10.1111/birt.12819
    BACKGROUND: Small for gestational age (SGA) and large for gestational age (LGA) are designations given to neonates based solely on birthweight, with no distinction made for maternal height. However, there is a possibility that maternal height is significantly correlated with neonatal birthweight, and if so, SGA and LGA cutoffs specific to maternal height may be a more precise and useful tool for clinicians. To explore this possibility, we analyzed the association between maternal height and ethnicity and neonate birthweight in women with low-risk, 37- to 40-week gestation, singleton pregnancies who gave birth vaginally between 2010 and 2017 (n = 354,488). For this retrospective cohort study, we used electronic obstetric records obtained from the National Obstetrics Registry in Malaysia.

    METHODS: National Obstetric Registry (NOR) data were used to calculate the 10th and 90th birthweight percentiles for each maternal height group by gestational age and neonatal sex. Multiple linear regression models, adjusted for maternal age, weight, parity, gestational age, and neonatal sex, were used to examine the association between neonate birthweight and maternal ethnicity and height. The following main outcome measures were assessed: small for gestational age (<10th percentile), large for gestational age (>90th percentile), and birthweight.

    RESULTS: The median height was 155 cm (IQR, 152-159), with mothers of Chinese descent being the tallest (median (IQR): 158 cm (154-162)) and mothers of Orang Asli (Indigenous) descent the shortest (median (IQR): 151 cm (147-155)). The median birthweight was 3000 g (IQR, 2740-3250), with mothers of Malay and Chinese ethnicity and Others having, on average, the heaviest babies, followed by other Bumiputeras (indigenous) mothers, mothers of Indian ethnicity, and lastly, mothers of Orang Asli ethnicity. For infants, maternal age, height, weight, parity, male sex, and gestational age were positively associated with birthweight. Maternal height had a positive association with neonate birthweight (B = 7.08, 95% CI: 6.85-7.31). For ethnicity, compared with neonates of Malay ethnicity, neonates of Chinese, Indian, Orang Asli, and other Bumiputera ethnicities had lower birthweights.

    CONCLUSION: Birthweight increases with maternal height among Malaysians of all ethnicities. SGA and LGA cutoffs specific to maternal height may be useful to guide pregnancy management.

    PMID: 10497665
    This study aims to determine the prevalence of and risk factors associated with retinopathy of prematurity (ROP) in very low birth weight (VLBW) infants. All premature VLBW infants, admitted into the neonatal intensive care unit of the University Hospital Kuala Lumpur, were screened from 4 weeks of life. Perinatal and neonatal data were retrieved from the infants' medical notes. Between August 1994 and July 1996, 100 infants had their eyes examined serially. Of the 15 (15%) infants with ROP, all were less than 31 weeks gestation, and only 1 infant had birth weight above 1250 g. Five (5%) infants had severe ROP; 4 infants underwent cryotherapy for stage 3 threshold disease. Infants with ROP, as compared to infants without ROP, had lower birth weight [mean (SEM) 993 (50) g versus 1205 (22) g, P < 0.001], lower gestational age [mean (SEM) 28.0 (0.4) weeks versus 30.1 (0.2) weeks, P < 0.001], higher rates of patent ductus arteriosus and chronic lung disease, greater number of radiographic examinations and episodes of late-onset suspected/confirmed sepsis, and required longer duration of supplemental oxygen, ventilation, xanthine, antibiotics and intralipid use, but were slower to establish full enteral feeds. On multivariate logistic regression analysis, birth weight < or = 1000 g [OR 2.38, 95% CI 1.25, 4.55, P = 0.009] and gestational age < or = 28 weeks [OR 2.86, 95% CI 1.47, 5.56, P = 0.002] were significant predictors of increased risk of this disease. In conclusion, ROP is strongly associated with smaller, more immature and sicker neonates. Prevention of prematurity would help reduce the incidence of this disease.

    PMID: 10730035
    A case-control study was carried out on 152 extremely low birthweight (ELBW, < 1000 g) infants born consecutively in a large Malaysian maternity hospital during a 21-month period to determine the significant predictors associated with survival at discharge. Forty-nine (32.2 per cent) of these infants survived and 103 (67.8 per cent) died. The survivors weighed significantly heavier (mean = 888 g, SD = 99) than infants who died (mean = 763 g, SD = 131; p < 0.0001). They were also of higher gestational age (mean = 28.7 weeks, SD = 2.2) than those who died (mean = 26.7 weeks, SD = 2.5; p < 0.0001). Logistic regression analysis showed that, after controlling for various confounders, only three factors were significantly associated with the survival of these infants. These were: (1) increasing birthweight of the infants (with every gram increase in birthweight, adjusted odds ratio of survival was: 1.009; 95 per cent CI 1.004, 1.015; p = 0.0006); (2) given nasal continuous positive airway pressure for treatment of respiratory distress syndrome (adjusted odds ratio of survival: 4.2; 95 per cent CI 1.2, 14.0; p = 0.02); and (3) given expressed breastmilk (adjusted odds ratio of survival: 57.5; 95 per cent CI: 7, 474; p = 0.0002). Maternal illness, intrapartum problems, ethnicity, gestational age, use of antenatal steroid, modes of delivery, Apgar scores, congenital anomalies, respiratory distress syndrome, persistent ductus arteriosus, septicemia, necrotising enterocolitis, chronic lung disease, oxygen therapy, intermittent positive pressure ventilation, surfactant therapy, and blood transfusion were not significant factors associated with increased survival.

  19. Comparison of morbidities in very low birthweight and normal birthweight infants during the first year of life in a developing country
    Boo NY, Ong LC, Lye MS, Chandran V, Teoh SL, Zamratol S, et al.
    J Paediatr Child Health, 1996 Oct;32(5):439-44.
    PMID: 8933407
    OBJECTIVE: To compare the morbidities in the very low birthweight (VLBW; < 1500 g) and normal birthweight (NBW; > or = 2500 g) Malaysian infants during the first year of life.

    METHODOLOGY: Prospective observational cohort study of consecutive surviving VLBW infants and randomly sampled NBW infants born in the Kuala Lumpur Maternity Hospital between 1 December 1989 and 31 December 1992. Infants were followed up regularly during the first year of life, after correction for prematurity.

    RESULTS: Compared with NBW infants (n = 106), VLBW infants (n = 127) had significantly higher risk of failure to thrive (odds ratio [OR] = 8.0, 95% confidence intervals [CI]: 1.1 to 354.3), wheezing (OR = 3.7, 95% CI: 1.6 to 9.3), rehospitalization (OR = 2.3, 95% CI: 1.1 to 5.0), cerebral palsy (OR = 8.6, 95% CI: 2.0 to 77.6), neurosensory hearing loss (OR = 12.0, 95% CI: 1.7 to 513.6) and visual loss (7.9 vs 0%, P = 0.002). The mean mental developmental index (MDI) and mean psychomotor developmental index (PDI) at 1 year of age were significantly lower among VLBW infants (MDI 99 [SD = 28], PDI 89 [SD = 25]) than NBW infants (MDI 106 [SD = 18], PDI 101 [SD = 18]) (95% CI for difference between means being MDI: -14.1 to -1.7; and PDI: -17.6 to -6.0). Logistic regression analysis showed that among VLBW infants: (i) male sex, Malay ethnicity and bronchopulmonary dysplasia were significant risk factors associated with wheezing; (ii) longer duration of oxygen therapy during the neonatal period, seizures after the post-neonatal period and wheezing were significant risk factors associated with rehospitalization; and (iii) longer duration of oxygen therapy during the neonatal period was a significant risk factor associated with adverse neurodevelopmental outcome during the first year of life.

    CONCLUSIONS: Compared with NBW infants, VLBW Malaysian infants had significantly higher risks of physical and neuro-developmental morbidities.

    PMID: 3678931
    Injectable vitamin A was given to six pregnant beef cows in their last third of pregnancy to study the effect of this vitamin in their calves. Average birth weight and growth rate of calves from the treated cows were higher than that of calves from the nontreated cows. Prepartum vitamin A injections also resulted in a significant increase (P less than 0.05) in the mean corpuscular volume (MCV), total serum protein and globulin fraction of serum protein in calves of treated cows.
