The early identification of asphyxiated infants at high risk of adverse outcomes and the early selection of those who might benefit from neuroprotective therapies are required. A prospective observational study was conducted to determine if there were any early clinical, neuroimaging or neurophysiological parameters that might predict the outcome in term newborns with asphyxia.

Combined Support Vector Machine (SVM) and Principal Component Analysis (PCA) was used to recognize the infant cries with asphyxia. SVM classifier based on features selected by the PCA was trained to differentiate between pathological and healthy cries. The PCA was applied to reduce dimensionality of the vectors that serve as inputs to the SVM. The performance of the SVM utilizing linear and RBF kernel was examined. Experimental results showed that SVM with RBF kernel yields good performance. The classification accuracy in classifying infant cry with asphyxia using the SVM-PCA is 95.86%.

Infant asphyxia is a condition due to insufficient oxygen intake suffered by newborn babies. A 4 to 9 million occurrences of infant asphyxia are reported each year by WHO. Early diagnosis of asphyxia is important to avoid complications such as damage to the brain, organ and tissue that could lead to fatality. This is possible with the automation of screening of infant asphyxia. Here, a non-invasive Asphyxia Screening Kit is developed. It is a Graphical User Interface that automatically detects asphyxia in infants from early birth to 6 months from their cries and displays the outcome of analysis. It is built with Matlab GUI underlied with signal processing algorithms, capable of achieving a classification accuracy of 96.03%. Successful implementation of ASK will assist to screen infant asphyxia for reference to clinicians for early diagnosis. In addition, ASK also provides an interface to enter patient information and images to be integrated with existing Hospital Information Management System.

OBJECTIVES: To identify the types of early cranial ultrasound changes that were significant predictors of adverse outcome during the first year of life in asphyxiated term infants.
METHODOLOGY: This was a prospective cohort study. Shortly after birth, cranial ultrasonography was carried out via the anterior fontanelles of 70 normal control infants and 104 asphyxiated infants with a history of fetal distress and Apgar scores of less than 6 at 1 and 5 min of life, or requiring endotracheal intubation and manual intermittent positive pressure ventilation for at least 5 min after birth. Neurodevelopmental assessment was carried out on the survivors at 1 year of age.
RESULTS: Abnormal cranial ultrasound changes were detected in a significantly higher proportion (79.8%, or n = 83) of asphyxiated infants than controls (39.5%, or n = 30) (P < 0.0001). However, logistic regression analysis showed that only three factors were significantly associated with adverse outcome at 1 year of life among the asphyxiated infants. These were: (i) decreasing birthweight (for every additional gram of increase in birthweight, adjusted odds ratio (OR) = 0.999, 95% confidence interval (CI) 0.998, 1.000; P = 0.047); (ii) a history of receiving ventilatory support during the neonatal period (adjusted OR = 8.3; 95%CI 2.4, 28.9; P = 0.0009); and (iii) hypoxic-ischaemic encephalopathy stage 2 or 3 (adjusted OR = 5.8; 95%CI 1.8, 18.6; P = 0.003). None of the early cranial ultrasound changes was a significant predictor.
CONCLUSIONS: Early cranial ultrasound findings, although common in asphyxiated infants, were not significant predictors of adverse outcome during the first year of life in asphyxiated term infants.

Advances in neonatal care now enable more infants to be kept alive despite clear clinical evidence of inevitable or imminent death on a life-support system. It is therefore no longer acceptable to the society that a patient is left to die in the hospital, without any form of treatment or intervention. We report a case of severe birth asphyxia, hypoxic-ischemic encephalopathy, neonatal seizures and left cephalohematoma. In spite of initial successful resuscitation, the infant could not survive until all possible methods of treatment were exhausted. This case illustrates one of many examples of the process involved in dealing with ending of life decision in a condition considered as futile.

A 2-month prospective study was carried out in a Kuala Lumpur maternity hospital to determine the antenatal and intrapartum factors associated with perinatal asphyxia in the Malaysian neonates. The incidence of perinatal asphyxia was 18.7 per 1000 livebirths. Of the 75 asphyxiated neonates born during this period, 70 (93.3 per cent) were of term or post-term gestation. The incidence of perinatal asphyxia was more common in the neonates with one of the following characteristics: low birth weight (< 2500 g), breech delivery, or delivery by instrumentation or lower segment Caesarean section (P < 0.001). Conditional logistic regression analysis of the asphyxiated and the control neonates in a nested case-control study (after controlling for sex, race, birth weight, modes of delivery, and maternal gravida) showed that there were two associated factors which were of statistical significance. These were: small-for-gestation neonates and the presence of intrapartum problems. Our study suggests that to reduce the incidence of perinatal asphyxia, the common causes of small-for-gestation neonates and the common types of intrapartum problems should be identified to enable appropriate preventive measures to be carried out.

A post-dated intra-uterine growth retarded male Malay baby was born to a 30-year-old mother gravida II by Caesarean section. Her previous pregnancy ended in still-birth. The baby was severely asphyxiated at birth. He was intubated and immediately admitted to the neonatal intensive care unit. He had anasarca, anaemia, purpura and firm, massive hepatosplenomegaly. X-rays revealed ascites and bilateral metaphysiitis of the long bones. The haemoglobin level was 5.0 gm/dl and PCV 18.3%. Coombs' test was negative. Prothrombin time (PT) and partial thromboplastin time (PTT) were prolonged. The baby and mother were positive for Venereal Disease Research Laboratory (VDRL) and the treponema pallidum haemagglutination assay (TPHA) tests. The baby was actively resuscitated but expired at three and a half hours of life due to overwhelming sepsis associated with severe anaemia and disseminated intravascular coagulation.

Thyroxine has been shown to have a beneficial effect on renal function in cases of impending renal failure in ani-mal studies.'5 Studies of the use of thyroxine in humans in impending renal failure are scarce. The aim of this study was to assess the effect of oral thyroxine on the renal function of asphyxiated term neonates who often have renal impairment.
A randomised control trial was conducted, involving 30 term asphyxiated neonates. The study group (n=15) was given thyroxine (50 pg) orally on days 1, 2 and 3 of life and placebo was given to the control group (n=15). Renal function was studied on day 1 and day 4 of life. The two groups did not differ significantly as regards gestational age, birth weight, severity of asphyxia, preg-nancy or delivery complications, fluids administered and drugs used. There was no significant difference in urine output, creatinine clearance and fractional excretion of sodium on day 1 but there was a trend towards a worse renal function on day 1 in the treatment group. The creatinine clearance was significantly better in the treat-ment group on day 4 (p = 0.017). Urine output and fractional excretion of sodium on day 4 were better in the treatment group but the differences did not reach statistical significance (p = 0.14 and 0.057 respectively). Statistical analysis on the differences between day 4 and day 1 showed statistical significance only for creatinine clearance: creatinine clearance day 4 minus creatinine clearance day 1 was 52.6 (±32.4) for the thyroxine group and 7.3 (±7.8) for the controls (p= 0.006).
These data support the hypothesis that thyroxine may have a significant beneficial effect on the renal function in term neonates with perinatal asphyxia. Thyroxine may be proven useful in future for patients with impending renal failure.

An analysis of perinatal statistics in Peninsular Malaysia from 1980 — 1989 was undertaken. The Perinatal Mortality Rate showed a 42% decrease over the 10 year period. The Perinatal Mortality Rate was higher among the Indian and Malay ethnic groups compared to the Chinese. This was largely contributed by the higher Stillbirth rate in the former 2 ethnic groups. The Indians have the highest rate of low birthweight babies. There is a decline in the rate of low birthweight babies born over the studied decade. The major causes of early neonatal mortality included problems asociated with prematurity, asphyxia neonatorum, septicaemia and congenital anomalies. Further epi-demiological research is required to identify other riskfactors which contribute to this ethnic biased perinatal mortality rates. Besides intensifying and upgrading current multifaceted approaches, interventional strategies need to be directed to the identified high risk groups. (Copied from article).

Third-generation cephalosporin resistant Enterobacteriaceae (TCRE) is a global concern especially in neonatal sepsis. We performed a secondary data analysis in a Thai neonatal intensive care unit to identify the risk factors for acquisition of TCRE sepsis and mortality of Enterobacteriaceae sepsis between 1991 and 2017. Multivariate logistic and Cox proportional regression were used for analysis. Numbers of neonates with TCRE and nonTCRE sepsis were 100 and 41 patients, respectively. Medians (interquartile ranges) of gestational age, birthweight, onset of sepsis and total hospital stay of neonates with Enterobacteriaceae sepsis were 32 (28, 38) weeks, 1670 (1025, 2750) grams, 11 (6, 25) days and 41 (22, 74) days, respectively. Univariate and multivariate analysis, neonates with TCRE sepsis were more likely to have birth asphyxia (adjusted odds ratio [aOR] = 2.6; 95% confidence interval [CI] 1.1-6.0; p = 0.02) and history of aminoglycoside exposure (aOR = 2.9; 95% CI 1.3- 6.7; p = 0.01). In-hospital case fatality rate from Enterobacteriaceae sepsis was 26% (36/141). In Cox regression, neonates with TCRE sepsis was not an independent risk of non-survivors, but septic shock (adjusted hazard ratio = 9.9; 95% CI 5.0-19.7, p < 0.001) increased 30-day mortality in the final model. Asphyxia and previous aminoglycoside consumption were risks of acquisition for neonatal TCRE sepsis while the burden was not a significant difference. Infection prevention and control must be strictly implemented in high multidrug-resistant area.
