Neurodevelopmental outcome of preterm infants with bronchopulmonary dysplasia.

The neurodevelopmental outcome of 78 infants with bronchopulmonary dysplasia (BPD) was compared with that of 78 control infants matched for birthweight. To determine the effect of the severity of BPD, 62 infants requiring oxygen at 36 weeks' postmenstrual age (sBPD) were compared with their matched controls. Infants were followed up to 2 years of age, corrected for prematurity, and were classified for neurological impairment, developmental delay, and neurodevelopmental disability. Seventy six (98%) BPD infants and 71 (91%) controls had follow up data available to two years. Neurological impairment, developmental delay, and neurodevelopmental disability occurred more frequently in infants with BPD than in controls but this was not significant. For infants with sBPD, the increased incidence of neurological impairment and definite developmental delay was not significant when compared with the controls, though neurodevelopmental disability occurred more frequently (odds ratio (OR) 3.6: 95% confidence intervals (CI) 1.1-11.8). Predictors of disability in infants with sBPD included periventricular haemorrhage (OR 19.4: 95% CI 4.3-86.6), ventricular dilatation (OR 12.8: 95% CI 2.9-57.3), and sepsis (OR 5.0: 95% CI 1.3-19.4). Adjusting for the presence of these factors, the association between BPD and disability was no longer apparent (OR 0.9: 95% CI 0.2-3.6). The findings suggest that BPD is not independently associated with adverse neurodevelopmental outcome

Water quality under the changing climatic condition: a review of the Indian scenario

The current work reviews the state of Indian water quality under the climate change regime. Rising temperatures will lead to higher concentration of pollutants like nutrients (nitrates, phosphates etc.), persistent organic pollutants and pesticides. Probable negative consequences include increase in harmful algal blooms, toxicity hazards in people etc. Rising temperatures could lead to release of higher amounts of fluoride and uranium due to prevalence of drier oxic conditions, and also arsenic due to release from iron (hydr)oxides. Implications on emerging contaminants, a new class of pollutants without any regulatory status, is not clearly understood. Prevalence of microbes in water is also predicted to increase. Coastal aquifers appear to be at risk from salt water intrusion. Conflicts on the international and national platform is predicted to rise due to issues with sharing of water. Lastly, we also discuss the sustainability options for water in India under a changing climatic regime, under three broad subcategories signifying the roles of (1) science, (2) policies and legal framework and the (3) people perspective, while also highlighting the existing lacunae.by Nilotpal Das, Chandan Mahanta and Manish Kuma
