Light drinking versus abstinence in pregnancy : behavioural and cognitive outcomes in 7-year-old children : a longitudinal cohort study

To assess whether light drinking in pregnancy is linked to unfavourable developmental outcomes in children. Design Prospective population-based cohort. Setting UK. Population Ten thousand five hundred and thirty-four 7-year-olds. Methods Quasi-experimental using propensity score matching (PSM) to compare children born to light (up to 2 units per week) and non-drinkers. Main outcome measures Behavioural difficulties rated by parents and teachers; cognitive test scores for reading, maths and spatial skills. Results Ordinary least squares (OLS) regression and PSM analyses are presented. For behavioural difficulties, unadjusted estimates for percentage standard deviation (SD) score differences ranged from 2 to 14%. On adjustment for potential confounders, differences were attenuated, with a loss of statistical significance, except for teacher-rated boys' difficulties. For boys, parent-rated behavioural difficulties: unadjusted, −11.5; OLS, −4.3; PSM, −6.8; teacher-rated behavioural difficulties: unadjusted, −13.9; OLS, −9.6; PSM, −10.8. For girls, parent-rated behavioural difficulties: unadjusted, −9.6; OLS, −2.9; PSM, −4.5; teacher-rated behavioural difficulties: unadjusted, −2.4; OLS, 4.9; PSM, 3.9. For cognitive test scores, unadjusted estimates for differences ranged between 12 and 21% of an SD score for reading, maths and spatial skills. After adjustment for potential confounders, estimates were reduced, but remained statistically significantly different for reading and for spatial skills in boys. For boys, reading: unadjusted, 20.9; OLS, 8.3; PSM, 7.3; maths: unadjusted, 14.7; OLS, 5.0; PSM, 6.5; spatial skills: unadjusted, 16.2; OLS, 7.6; PSM, 8.1. For girls, reading: unadjusted, 11.6; OLS, −0.3; PSM, −0.5; maths: unadjusted, 12.9; OLS, 4.3; PSM, 3.9; spatial skills: unadjusted, 16.2; OLS, 7.7; PSM, 6.4. Conclusion The findings suggest that light drinking during pregnancy is not linked to developmental problems in mid-childhood. These findings support current UK Department of Health guidelines on drinking during pregnancy

Companion animals as being-objects: the role of the self/other binary in the human-animal bond

This research project is an investigation into the human-dog bond and the practice of pet adoption and pet surrender at the East Baton Rouge Parish Animal Control Center. The human-dog bond is an excellent vehicle for an investigation into how we create categories of other because it is a highly complex and intersubjective relationship with deep evolutionary roots that is often reduced to a relationship between possessor and possessed in which cultural, historical, and biological contexts are not considered. It is a relationship in which constructed meaning is taken for fact. This thesis explores how animal control centers both resist and reinforce the perception of companion animals as being-objects. The term being-objects is used to denote the tactic we employ by categorizing companion animals as beings when convenient and as disposable objects when necessary. When we categorize companion animals as objects, we other them. We create an unfair identity for them in order to distance ourselves from an uncomfortable confrontation with the reality of pet euthanasia. The author of this thesis will explore how meaning is socially constructed in the E.B.R.P. Animal Control Center through a discussion of the way we speak about animal control centers, the location and arrangement of the E.B.R.P. Animal Control Center, and the performance of adoption and surrender processes within the center

Light drinking during pregnancy : still no increased risk for socioemotional difficulties or cognitive deficits at 5 years of age?

Background This study examines the relationship between light drinking during pregnancy and the risk of socioemotional problems and cognitive deficits at age 5 years. Methods Data from the nationally representative prospective UK Millennium Cohort Study (N=11 513) were used. Participants were grouped according to mothers' reported alcohol consumption during pregnancy: never drinker; not in pregnancy; light; moderate; heavy/binge. At age 5 years the strengths and difficulties questionnaire (SDQ) and British ability scales (BAS) tests were administered during home interviews. Defined clinically relevant cut-offs on the SDQ and standardised scores for the BAS subscales were used. Results Boys and girls born to light drinkers were less likely to have high total difficulties (for boys 6.6% vs 9.6%, OR=0.67, for girls 4.3% vs 6.2%, OR=0.69) and hyperactivity (for boys 10.1% vs 13.4%, OR=0.73, for girls 5.5% vs 7.6%, OR=0.71) scores compared with those born to mothers in the not-in-pregnancy group. These differences were attenuated on adjustment for confounding and mediating factors. Boys and girls born to light drinkers had higher mean cognitive test scores compared with those born to mothers in the not-in-pregnancy group: for boys, naming vocabulary (58 vs 55), picture similarities (56 vs 55) and pattern construction (52 vs 50), for girls naming vocabulary (58 vs 56) and pattern construction (53 vs 52). Differences remained statistically significant for boys in naming vocabulary and picture similarities. Conclusions At age 5 years cohort members born to mothers who drank up to 1–2 drinks per week or per occasion during pregnancy were not at increased risk of clinically relevant behavioural difficulties or cognitive deficits compared with children of mothers in the not-in-pregnancy group

Isolation & Characterization of Bacteria in the Built Environment: Measuring The Effect of Pharmaceuticals on Growth

This work reports the isolation and characterization of bacteria from the built environment at Gettysburg College in Gettysburg, PA. Surfaces of a water fountain on campus were swabbed and serially streaked to isolate multiple bacteria on R2A agar. Following multiple rounds of growth, the unknown microbial candidates were narrowed to two visibly­distinct organisms. Morphological characterization and phylogenetic identification based on 16S rDNA sequencing revealed that the isolates were Chryseobactierum hispalense and Microbacterium maritypicum. We report synergistic biofilm formation between Chryseobactierum hispalense and Microbacterium maritypicum. The contamination of drinking water with varying levels of personal care products and pharmaceuticals (PCPPs) is well documented. Additionally, these environmental pollutants and their derivatives affect aquatic life, as illustrated with effect of the antidepressant fluoxetine on mudsnails. To determine if previously reported contaminants affect freshwater bacteria, we assessed both planktonic growth and biofilm formation following exposure to nalidixic acid (non­fluorinated quinolone antibiotic), diphenhydramine (over­the­counter drug Benadryl), and fluoxetine (Prozac)

Transitioning & Preparing Library Students: Canadian PD Programs

In an increasingly competitive job market, extra-curricular professional development (PD) opportunities prepare and equip Masters-level LIS students to secure employment and excel in their careers. In addition to reviewing and examining existing extra-curricular PD initiatives available through current ALA accredited Masters-level programs in Canada, a potential structure for developing, framing, and delivering PD programs is proposed. Findings from a review of university websites reveal a lack of consistency across schools in PD opportunities geared to transitioning and preparing students for future careers. Prospective directions for educational organizations to further develop their program offerings for students and recent graduates are explored
