ABSTRACT BACKGROUND: Most research examining birth history (i.e. related birth complications) and developmental milestone achievement follow outcomes for infants at-risk with very specific birth weight categories and gestational age classifications. The purpose of this study was to examine how birth weight relates to infants' birth histories and developmental milestone achievement when they fall into a variety of birth weight and gestational age categories. METHODS: In the current study, we examined birth histories and onset ages for developmental milestones by analyzing a convenience sample of anonymous existing data from 663 developmental histories completed by parents at the time of an initial evaluation at a pediatric outpatient occupational therapy clinic. Infants fell into 3 birth weight categories; low birth weight (LBW), normal birth weight (NBW), and high birth weight (HBW) and 3 gestational age classifications considered with birth weight; small for gestational age (SGA), appropriate for gestational age (AGA), and large for gestational age (LGA). RESULTS: NBW, AGA, and SGA infants with related birth complications had lower birth weights than infants without birth complications. Larger birth weights were associated with earlier ages for independent sitting for HBW infants, earlier ages for eating solids for NBW infants, and earlier walking onsets for LBW and NBW infants. Higher birth weights were also linked with rolling at a younger age for LGA infants, earlier walking and speaking words for AGA infants, and sooner independent sitting for SGA and AGA infants. CONCLUSIONS: Our findings suggest that birth weight and gestational age categories provide unique insights into infants' birth history and developmental milestone achievement.

    ABSTRACT: Little is known about how obesity relates to motor planning and skills during functional tasks. We collected 3-D kinematics and kinetics as normal weight (n=10) and overweight/obese (n=12) children walked on flat ground and as they crossed low, medium, and high obstacles. We investigated if motor planning and motor skill impairments were evident during obstacle crossing. Baseline conditions showed no group differences (all ps>.05). Increased toe clearance was found on low obstacles (p=.01) for the overweight/obese group and on high obstacles (p=.01) for the normal weight group. With the crossing leg, the overweight/obese group had larger hip abduction angles (p=.01) and medial ground reaction forces (p=.006) on high obstacles and high anterior ground reaction forces on low obstacles (p=.001). With the trailing leg, overweight/obese children had higher vertical ground reaction forces on high obstacles (p=.005) and higher knee angles (p=.01) and anterior acceleration in the center of mass (p=.01) on low obstacles. These findings suggest that differences in motor planning and skills in overweight/obese children may be more apparent during functional activities.

    ABSTRACT: Background Receptors for advanced glycation end-products (RAGE) are immunoglobulin-like pattern recognition receptors abundantly localized to lung epithelium. Our research demonstrated that primary tobacco smoke exposure increases RAGE expression and that RAGE partly mediates pro-inflammatory signaling during exposure. However, the degree to which RAGE influences developing lungs when gestating mice are exposed to secondhand smoke (SHS) has not been determined to date. Methods Timed pregnant RAGE null and wild type control mice were exposed to 4 consecutive days of SHS from embryonic day (E) 14.5 through E18.5 using a state of the art nose-only smoke exposure system (Scireq, Montreal, Canada). RAGE expression was assessed using immunofluorescence, immunoblotting, and quantitative RT-PCR. TUNEL immunostaining and blotting for caspase-3 were performed to evaluate effects on cell turnover. Matrix abnormalities were discerned by quantifying collagen IV and MMP-9, a matrix metalloprotease capable of degrading basement membranes. Lastly, TNF-α and IL-1β levels were assessed in order to determine inflammatory status in the developing lung. Results Pulmonary RAGE expression was elevated in both dams exposed to SHS and in fetuses gestating within mothers exposed to SHS. Fetal weight, a measure of organismal health, was decreased in SHS-exposed pups, but unchanged in SHS-exposed RAGE null mice. TUNEL assessments suggested a shift toward pulmonary cell apoptosis and matrix in SHS-exposed pups was diminished as revealed by decreased collagen IV and increased MMP-9 expression. Furthermore, SHS-exposed RAGE null mice expressed less TNF-α and IL-1β when compared to SHS-exposed controls. Conclusions RAGE augmentation in developing pups exposed to maternal SHS weakens matrix deposition and influences lung inflammation.

    ABSTRACT: Periodic screening for developmental delays (DD) could avert the incidence of disability among children. However, such routine programme is yet to take off in rural welfare clinics in Ghana. Mothers of under-5 children who were attending rural child welfare clinic participated in this study. The socio-demographic data of the mothers and their children were recorded. The children were screened to assess their gross motor skills, fine motor skills, communication skills, and problem solving/cognition and social/personal interaction using Ages and Stages Questionnaire. Score below the threshold points on a developmental domain defines DD for a child. Data analysis involved percentages and frequency while Chi-square was performed to determine the associations between the selected socio-demographic risk factors and DD. Alpha value was set at p < 0.05. Three hundren and thirty (330) children were screened and majority 60(18%), were found within the age range 3 months 1 day to 5 months 0 day. 251(76%) had normal weight (2.5 kg-3.5) while 26(7.6%) were underweight (<2.5 kg). Generally, 147(44.6%) of the children had DD in the different domains of the questionnaires. 41(12.4%) had DD in social/personal interaction while 19(5.8%) were delayed in the communication domain. Birth weight and duration of gestation were significantly associated with communication domain while the level of education of the mothers and duration of gestation were significantly associated with gross motor domain. An appreciable proportion of the children were found to experience developmental delays and the most prevalent occurence was in personal/social interaction. Birth weight, gestational age and maternal educational level provide insight into a link with communication and gross motor skills.
