Neonatal Deaths

In a 21-month period, 225 simians were born at the New England Regional Primate Research Center. Of these, 141 (63%) survived the neonatal period, and 84 (37%) were either born dead or died during the first 30 days of life. Sixty-two of the 84 neonatal deaths occurred during the perinatal period (0–7 days of life). In four macaque species studied, groups of infants that were high and low survival risks were established by examining weight-specific death rates. Criteria for establishing immaturity by birth weight were suggested in Saguinus oedipus and Saimiri sciureus.

In Reply.— Sepkowitz's arguments are flawed by his use of proportional mortalities instead of actual death rates. The low proportion of neonatal deaths occurring in the first four hours in an Oklahoma community hospital may indeed reflect a favorable first-four-hour death rate. But it might also be due to an unfavorable four-hour to 28 day death rate. Without the actual rates no conclusion can be drawn. Although it is true (as pointed out in our article) that some of the deaths averted in the first four hours at level 3 units were deferred to later in the neonatal period, a statistically significant and clinically important mortality advantage for low-birth-weight level 3 births was seen in all of our analyses, extending out as far as 3 months of age.1

Background: A baby’s weight at birth is a strong indicator of newborn health and nutrition. Low birth weight (LBW) babies are more susceptible to morbidities and mortality in early neonatal period than normal birth weight (NBW) babies. Among neonatal deaths, 80% occurs in LBW / preterm babies and 75% of total neonatal deaths occur in early neonatal period. The present study was undertaken to know the incidence and early neonatal outcome of LBW babies in rural area.Methods: Prospective observational study was conducted in babies born with <2.5 kg (LBW) birth weight.Results: The incidence of LBW babies was 25.07% with almost an equal contribution from preterm (50.46%) and Term Intra Uterine Growth Restricted (IUGR) (49.53%) babies. The most common morbidity found in LBW babies was Jaundice (40.09%) followed by respiratory distress (18.16%), sepsis (8.72%) and apnea (4.48%). Preterm-LBW babies had more morbidities in terms of apnea (100%), birth asphyxia (88.88%), respiratory distress (87.01%%), sepsis (80.55%) and jaundice (67.64%). Early neonatal mortality was 21.22 per 1000 live births. Mortality was 100% for babies <1 kg in birth weight, 16% in 1-1.499 kg group and 0.75% in 1.5-2.499 kg group in early neonatal period. According to gestational age, mortality in preterm-LBW babies was 88.88% and 11.11% in Term IUGR-LBW babies. The most common cause of death in LBW babies was birth asphyxia (44.44%) followed by hyaline membrane disease (HMD) (33.33%).Conclusions: The present study revealed that preterm babies contributed 50% to incidence of LBW babies. Morbidity and mortality in LBW babies were inversely related to birth weight and gestational age.

Introduction: The current cohort study was conducted to determine the frequency and compare the mortality rate with associated characteristics among low birth weight and normal birth weight infants during the neonatal period at a tertiary healthcare facility, Karachi. Methodology: Close-ended structured questionnaires were used to collect information from the parents of 500 registered neonates at the time of birth. Follow-ups by phone on the 28th day of life were done to determine the mortality among low birth weight and normal birth weight babies during the neonatal period. Results: The neonatal mortality rate ranged from as low as 2.4% in the normal birth weight and 16.4% in the low birth weight categories to as high as 96% in the very low birth weight category. Respiratory distress syndrome (24.2%) and sepsis (18.2%) were reported as the leading causes of neonatal deaths. The babies’ lengths of stay ranged from 2 to 24 hours, and around 90% of neonatal deaths were reported in the first seven days of life. More than 6% of neonates died at home, and 7.6% of the deceased babies did not visit any healthcare facility or doctor before their death. In the 12–15 hours before their deaths, 13.6% of the deceased babies had been unattended. Around 90% of the deceased babies were referred from a doctor or healthcare facility. Conclusions: The present estimates of neonatal mortality are very high among low birth weight and very low birth weight categories. Infectious diseases, including respiratory distress syndrome (24.2%) and sepsis (18.2%), were leading causes of neonatal deaths.

ABSTRACT Rhesus monkeys and other nonhuman Old World primates are naturally infected with lymphocryptoviruses (LCV) that are closely related to Epstein-Barr virus (EBV). A rhesus LCV isolate (208-95) was derived from a B-cell lymphoma in a simian immunodeficiency virus-infected rhesus macaque. The EBNA-2 homologues from 208-95 and a previous rhesus LCV isolate (LCL8664) were polymorphic on immunoblotting, so the EBNA-2 genes from these two rhesus LCV were cloned, sequenced, and compared. The EBNA-2 genes have 40% nucleotide and 41% amino acid identities, and the differences are similar to those between the type 1 and type 2 EBV EBNA-2. Sequence from a portion of the LMP1 gene which is extremely divergent among different LCV was virtually identical between the 208-95 and LCL8664 strains, confirming a common rhesus LCV background. Thus, the EBNA-2 polymorphism defines the presence of two different rhesus LCV types, and both rhesus LCV types were found to be prevalent in the rhesus monkey population at the New England Regional Primate Research Center. The existence of two rhesus LCV types suggests that the selective pressure for the evolution of two LCV types is shared by human and nonhuman primate hosts.

Abstract BackgroundUnder-five mortality in Kenya has declined over the past two decades. However, the reduction in the neonatal mortality rate has remained stagnant. In a country with weak civil registration and vital statistics systems, there is an evident gap in documentation of mortality and its causes among low birth weight (LBW) and preterm neonates. We aimed to establish causes of neonatal LBW and preterm mortality in Migori County, among participants of the PTBI-K (Preterm Birth Initiative-Kenya) study.MethodsThis was a cross sectional study whereby Verbal and social autopsy (VASA) interviews were conducted with caregivers of deceased LBW and preterm neonates delivered within selected 17 health facilities in Migori County, Kenya. The probable cause of death was assigned using the WHO International Classification of Diseases (ICD-10). ResultsBetween January 2017 to December 2018, 3175 babies were born preterm or LBW, and 162 (5.1%) died in the first 28 days of life in 17 participating health facilities in the PTBI-K project. VASA was conducted among 88 (53.7%) neonatal deaths. Almost half (38, 43.2%) of the deaths occurred within the first 24 hours of life. Birth asphyxia (45.5%), neonatal sepsis (26.1%), respiratory distress syndrome (12.5%) and hypothermia (11.0%) were the leading causes of death. In the early neonatal period, majority (54.3%) of the neonates succumbed to asphyxia while in the late neonatal period majority (66.7%) succumbed to sepsis. Delay in seeking medical care was reported for 4 (5.8%) of the neonatal deaths. ConclusionDeaths among LBW and preterm neonates occur early in life due to preventable causes. This calls for enhanced intrapartum and immediate postpartum care interventions targeting asphyxia, sepsis, respiratory distress syndrome and hypothermia.
