Maternal height and child mortality
(JAMA 2009 ; 301:1691-1701) |
Data were retrieved from the 2005-2006 National Family Health Survey-3 in
India (released in 2008). The study population constituted a nationally
representative cross-sectional sample of singleton children aged 0 to 59
months (n = 50 750) to mothers aged 15 to 49 years from all 29
states of India. Information on children was obtained by a face-to-face
interview with mothers, with a response rate of 94.5%. In adjusted models,
a 1-cm increase in maternal height was associated with a decreased risk of
child mortality, underweight, stunting, wasting, and anemia. Children born
to mothers who were less than 145 cm in height were 1.71 times more likely
to die compared with mothers who were at least 160 cm in height.
Comment In a nationally representative sample of households in
India, maternal height was inversely associated with child mortality and
anthropometric failure.

Fetal antiepileptic drug exposure and
cognition (N Engl J Med 2009; 360:1597-1605). |
Between 1999 and 2004, pregnant women with epilepsy who were taking a
single antiepileptic agent were enrolled in a prospective, observational,
multicenter study in the United States and the United Kingdom. This report
focuses on a planned interim analysis of cognitive outcomes in 309
children at 3 years of age. After adjustment for maternal IQ, maternal
age, antiepileptic-drug dose, gestational age at birth, and maternal
preconception use of folate, the mean IQ of children exposed to valproate
was lower than those exposed to lamotrigine, phenytoin and carbamazepine.
The association between valproate use and IQ was dose dependent.
Comment Valproate should not be used as a first-choice drug in
women of childbearing potential.

Magnesium sulfate improves outcome in
severe perinatal asphyxia (Pediatrics 2009; 123: e764-769). |
Forty term (³37 weeks of gestation)
neonates with severe perinatal asphyxia were
randomly assigned to receive either 3 doses of
magnesium sulfate infusion at 250 mg/kg per dose 24
hours apart (treatment group) or 3 doses of normal
saline infusion (placebo group), in addition to supportive
care. At discharge, 22%
of infants in the treatment group had neurological
abnormalities, compared with 56% of infants in the
placebo group. Neuroimaging on day 14 yielded abnormal findings for fewer
infants in the treatment group than in the placebo
group. Infants in the treatment group were more likely to be receiving
oral feedings (sucking) at discharge. Good short-term outcomes at
discharge occurred for 77% of the patients in the
treatment group, compared with 37% of the patients
in the placebo group.
Comment Postnatal magnesium sulfate treatment improves neurological
outcomes at discharge for term neonates with severe perinatal
asphyxia.

Highway traffic and asthma (Int J
Environ Health Res 2009; 19:139-145.) |
Cross-sectional analyses were conducted to evaluate the effects of
exposure to highway traffic on pulmonary function in Fresno, California.
Traffic and spirometry data were available for 214 children (enrolment
ages six to 11 years). Evaluation of effect modification by FEV(25-75)/FVC
(a measure of intrinsic airway size) showed that all pulmonary function
measures of flow were significantly inversely related to a traffic metric
that incorporates traffic intensity and roadway proximity.
Comment Proximity of the residence to highway
traffic is associated with lower pulmonary functions.
