This study aimed to explore the association between hyperglycemia in pregnancy (type 2 diabetes (T2D) and gestational diabetes mellitus (GDM)) and child developmental risk in Europid and Aboriginal women.

PANDORA is a longitudinal birth cohort recruited from a hyperglycemia in pregnancy register, and from normoglycemic women in antenatal clinics. The Wave 1 substudy included 308 children who completed developmental and behavioral screening between age 18 and 60 months. Developmental risk was assessed using the Ages and Stages Questionnaire (ASQ) or equivalent modified ASQ for use with Aboriginal children. Emotional and behavioral risk was assessed using the Strengths and Difficulties Questionnaire. Multivariable logistic regression was used to assess the association between developmental scores and explanatory variables, including maternal T2D in pregnancy or GDM.

After adjustment for ethnicity, maternal and child variables, and socioeconomic measures, maternal hyperglycemia was associated with increased developmental “concern” (defined as score ≥1 SD below mean) in the fine motor (T2D odds ratio (OR) 5.30, 95% CI 1.77–15.80; GDM OR 3.96, 95% CI 1.55–10.11) and problem-solving (T2D OR 2.71, 95% CI 1.05–6.98; GDM OR 2.54, 95% CI 1.17–5.54) domains, as well as increased “risk” (score ≥2 SD below mean) in at least one domain (T2D OR 5.33, 95% CI 1.85–15.39; GDM OR 4.86, 95% CI 1.95–12.10). Higher maternal education was associated with reduced concern in the problem-solving domain (OR 0.27, 95% CI 0.11–0.69) after adjustment for maternal hyperglycemia.

Maternal hyperglycemia is associated with increased developmental concern and may be a potential target for intervention so as to optimize developmental trajectories.

OBJECTIVES/SPECIFIC AIMS: 1) Describe strategies pediatric providers perceive improve chlamydia screening of sexually active female adolescents (SA), and 2) describe barriers to regular screening of SA for chlamydia METHODS/STUDY POPULATION: Using qualitative methods, 14 general pediatric providers across 7 clinical sites in Vermont were interviewed to ascertain best practices and remaining challenges. Semi-structured interviews lasting 30-45 minutes were audiotaped and transcribed. Chlamydia screening rates provided by BCBS-VT were used to categorize participant responses across three performance tiers, data were coded, and themes identified within these tiers. RESULTS/ANTICIPATED RESULTS: Facilitators: When asked to describe facilitators of chlamydia screening, providers in the top tier of chlamydia screening emphasized the importance of adequate insurance to cover the cost of testing. Providers in the middle performance tier cited use of pre-visit questionnaires, and those in the bottom performance tier identified no best practices. Other strategies included improving physician confidence and awareness, establishing practice- and individual-level routines, and providing strong leadership and communication of local screening rates. Barriers: Across the 3 performance tiers, the most common challenges to consistent chlamydia screening were threats to patient confidentiality, cost of the screening test, and requirement for patient disclosure of sexual activity. Less commonly, providers were concerned that adolescent patients were not reliable to obtain screens off-site, or fill treatment prescriptions without the help of a parent. DISCUSSION/SIGNIFICANCE OF IMPACT: The need for systematic, confidential, and inexpensive means for screening SA for chlamydia was highlighted in both the best practices and challenges described by providers of pediatric care in the suburban practice setting. Policy and practice interventions may target these needs to improve the reproductive health of female adolescents.

This study aimed to determine the prevalence and assemblages of Giardia duodenalis present in Scottish beef and dairy cattle at different ages, to try to ascertain if cattle could play a role in the spread of zoonotic assemblages of Giardia. A total of 388 fecal samples (128 beef and 253 dairy, seven of unknown breed) were collected from 19 farms in Scotland. Samples were sub-divided by host age, 1, 2, 3, 4, 5 and 6, 7–24 and ⩾25 weeks. DNA was extracted and tested by PCR to detect G. duodenalis DNA. Of the 388 samples, 126 tested positive, giving an overall prevalence of 32.5%, with positive samples being observed in all age groups tested. The prevalence in dairy cattle was 44.7% (113/235), which was significantly higher (P < 0.001) than the prevalence in beef cattle 10.1% (13/128). Sequence analysis demonstrated the presence of assemblage E (77.2%, sequence types E-S1–E-S5), assemblage B (18.2%) and assemblage A (sub-assemblages AI-AII) (4.6%). These data demonstrate that G. duodenalis is found routinely in both dairy and beef cattle throughout Scotland; the presence of assemblages A and B also indicates that cattle may play a role in the spread of potentially zoonotic assemblages of Giardia.
