Neurological an neurobehavioral differences between preterm infants at term and full-term newborn infants.

Estimating acute cardiorespiratory effects of ambient volatile organic compounds

The environmental perspective favors using chronological age, as it places higher importance on the role of external factors in the development of preterm infants 30,32 while partial correction intends to counter-balance the full correction and no correction approaches. For ce, our team at Johns Hopkins used national databases for mortality and morbidity in time-series analyses, thereby maximizing sample size and the potential to explore informative heterogeneity in effect estimates across the country.

Fresh vehicle emissions contain immense numbers of small particles, nanometers in aerodynamic diameter at their formation; as distance from the roadway increases, the particles quickly grow in size through agglomeration and change in composition through loss of volatile components and chemical transformations.

Environ Health Perspect ; 6: Not only do stress and medical complications make the premature births qualitatively different from full-term births, but also the long period in the incubator and the early influence of gravidity have an impact on preterm postural development at and after term To understand what the VOCs might be surrogates for, we performed an additional sensitivity analysis controlling for selected major pollutants one at a time in each VOC indicator pollutant model.

On the other hand, overdiagnosis of a developmental delay leads to unnecessary referrals to therapeutic interventions, which in turn, creates unwarranted anxiety for the parents 19, Gross motor milestones in preterm infants: Respiratory disease associated with community air pollution and a steel mill, Utah Valley. Predictors of development in premature infants from low-income families: Therefore, the warnat child may have different score outcome depending on the examiner approach, ranging from significant delay to normal When assessing preterm motor development by Peabody Developmental Motor Scale, age correction should be used at least up to 18 months of age 13but in an earlier study, the claificacion author 14 reported the need for correcting up to one year.


Table 1 shows the general data of the study group. Use of chronological and adjusted ages to compare motor development of healthy preterm and fullterm infants. Recommendations for further accountability research were offered in a report of a workshop held by the HEI.

We grouped these VOCs by chemical structure with the idea that this grouping may enhance the understanding of their health associations from commonalities that are related sarnst their structures, such as toxicity, source, and atmospheric process.

Looking back in time: Random effect meta-analysis In the joint effect analysis, we considered the individual pollutant effects as fixed, and estimated a combined effect per increase in all pollutants in a group.

Air quality measurements for the aerosol research and inhalation epidemiology study. N Engl J Med ; 5: Ambient air pollution and flasificacion department visits for asthma: Schwartz J, Zanobetti A.

Hagen JA, et al. Seven infants were excluded during the follow-up: We found that full age correction should be used to assess preterm motor development throughout the first year of corrected age.


Overall, we found that hydrocarbon groups, particularly the alkene and alkyne groups, were associated with emergency department visits for cardiovascular diseases, while the ketone group was associated with asthma visits.

The estimated associations between emergency department visits of cardiovascular diseases and the alkene and alkyne groups had little change compared to those in the primary analysis using the indicator pollutant approach, while the estimated associations for other hydrocarbon asrnat were closer to the null Table 3.

To capture the contribution of different pollutants within a group, we estimated a joint effect per IQR increase in all pollutants of a group as follows:.

Our results suggest that, when using AIMS, scores should be corrected for the degree of prematurity to more accurately identify infants with real delay, which is in agreement with AIMS criteria Immediate priorities clasificacin a long-range research portfolio. This commentary accompanies papers giving the results from the ESCALA project, a multi-city study in Latin America that has an overall goal of providing policy-relevant results.

Siegel 21 used full correction only in the early months, whereas Lems et al. We used 3-day moving average of lags 0, 1, and 2 pollution levels in models predicting asthma ED visits. The unit is ppb-C and the limit of detection LOD clasificaciin 0. Gesell A, Amatruda CS.
