Past and current research has clarified some of the rational bases of KMC and has provided evidence for its effectiveness and safety, although more research is needed to clearly define the effectiveness of the various components of the intervention in different settings and for different therapeutic goals.
In resource-poor settings where HIV PCR testing in an environment of good laboratory practice is feasible, a single 6-week HIV DNA PCR test can increase identification of HIV-infected children substantially from current levels. Further operational research on how best to implement and monitor such a diagnostic protocol in specific local settings, especially in breast-fed infants, is necessary.
The epidemiology of invasive Streptococcus agalactiae (GBS) disease was evaluated in South African children. Records of 208/220 children in whom GBS was isolated between January 1997 and December 1999 were reviewed. These included 63%, 31.7% and 5.3% children with early- (EOD, <7 days of age), late- (LOD, age 7-90 days) and childhood-onset disease (COD, age >90 days), respectively. The overall burden of EOD and LOD were 2.06 and 1/1000 live births, respectively. The overall mortality was 19.8% and 13.6% for infants with EOD and LOD, respectively. Risk factors for mortality in infants with EOD and LOD included septic shock (82.1% vs 1.9%), prematurity (35.2% vs 9.6%), low birthweight (29.2% vs 11.0%) and a leucocyte count <5000/mm(3) (43.5% vs 18.6%). Eight (72.7%) of 11 children with COD had an immunosuppressive, predisposing cause for invasive bacterial disease. In infants with EOD and LOD, serotype III isolates caused 49.2% and 75.7% of disease, respectively, and, together with serotype Ia isolates, caused 78.9% and 100% of invasive disease, respectively. Invasive GBS disease is common in South African infants and current strategies aimed at reducing the burden of the disease should be reconsidered.
The components of the Kangaroo Mother Care (KMC) intervention, their rational bases, and their current uses in low‐, middle‐, and high‐income countries are described. KMC was started in 1978 in Bogotá (Colombia) in response to overcrowding and insufficient resources in neonatal intensive care units associated with high morbidity and mortality among low‐birthweight infants. The intervention consists of continuous skin‐to‐skin contact between the mother and the infant, exclusive breastfeeding, and early home discharge in the kangaroo position. In studies of the physiological effects of KMC, the results for most variables were within clinically acceptable ranges or the same as those for premature infants under other forms of care. Body temperature and weight gain are significantly increased, and a meta‐analysis showed that the kangaroo position increases the uptake and duration of breastfeeding. Investigations of the behavioral effects of KMC show rapid quiescence. The psychosocial effects of KMC include reduced stress, enhancement of mother–infant bonding, and positive effects on the family environment and the infant's cognitive development.
Conclusion: Past and current research has clarified some of the rational bases of KMC and has provided evidence for its effectiveness and safety, although more research is needed to clearly define the effectiveness of the various components of the intervention in different settings and for different therapeutic goals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
