RESUMO
OBJECTIVE: Pediatric asthma emergency department (ED) visits and repeat visits place a substantial burden on healthcare. National and provincial level studies demonstrate geographic variation in asthma ED visits and links to marginalization, but preclude translation into practical targeting of healthcare delivery. It is important to understand the relationship between pediatric asthma ED visits and marginalization at a more granular level. To map the city-level geographic variation in pediatric asthma ED visit and re-visit rates at the Children's Hospital of Eastern Ontario (CHEO) in Ottawa, Canada and the relationship with marginalization. METHODS: We performed a single center retrospective cohort study of children ages 1-17 with one or more ED visits for asthma at the CHEO in Ottawa. Using postal codes, we linked patients to census tracts. Per census tract, we mapped pediatric asthma ED visit and re-visit rates within one year and identified overlap with the Ontario Marginalization Index. RESULTS: Of 1,620 children with an index ED visit, 18.5% had a repeat ED visit. We identified 10 hot spot census tracts each for pediatric asthma ED visit and re-visit rates. We identified an overlap between urban hot spots and areas with high ethnic concentration or low dependency. CONCLUSION: At a granular, city-wide level, pediatric asthma ED visit and re-visit rates are heterogeneous. Urban hot spots, in contrast to rural, have more overlap with marginalization, especially ethnic concentration. These methods can be used in other jurisdictions to inform practical community strategies for geographically-targeted prevention of pediatric asthma-related ED visits in vulnerable areas.Abbreviations:ED:Emergency department;CHEO:Children's Hospital of Eastern Ontario;PRAM:Pediatric Respiratory Assessment Measure;ON-Marg:Ontario Marginalization Index;SES:Socioeconomic status;US:United States.Supplemental data for this article can be accessed at publisher's website.

INTRODUCTION: Collins et al developed a histology scoring system (EoE HSS) to assess multiple pathologic features. The aim of this study is to identify if the EoE HSS can better detect endoscopic and symptom improvement vs the Peak Eosinophilic Count (PEC). METHODS: A retrospective chart review was performed for patients during 2014-2016. All patients ≤18 years old with a diagnosis of EoE and whose records included initial and follow-up upper gastrointestinal endoscopies were included. Severity and extent of endoscopic features were scored using 8 parameters, from normal to maximum change for each location of the esophageal biopsy. RESULTS: Forty patients with EoE were included in the study, of which 35 (87.5%) patients demonstrated symptom and 25 (62.5%) endoscopic improvement at the time of follow-up. In the proximal esophagus, the EoE HSS outperformed the change in eosinophil count of the Children's Hospital of Eastern Ontario (CHEO) practice in predicting endoscopic improvement by 16.8% when examining the change in grade and 17.1% when examining the change in stage scores. CONCLUSIONS: At our institution, adoption of the EoE HSS in assessing biopsies of EoE patients might be warranted, compared to the traditional practice. However, a bigger sample size may give a more robust difference in all locations.

OBJECTIVE: Previous analyses of neonatal intensive care units (NICU) antimicrobial stewardship programs have identified key contributors to overall antibiotic use, including prolonged empiric therapy >48 hours for early-onset sepsis (EOS). However, most were performed in mixed NICU settings with onsite birthing units, resulting in a high proportion of inborn patient admissions. The study aimed to describe and analyze the most common reasons for antimicrobial use in an outborn tertiary care NICU. STUDY DESIGN: This was a 10-month review of all antimicrobial doses prescribed in a 20-bed level III NICU. The primary outcome was the total days of therapy (DOT) and length of therapy (LOT) for each clinical indication. Secondary outcomes included total DOT for each antimicrobial and appropriateness of antimicrobial courses. RESULTS: Of 235 antibiotic courses and 1,899 DOT (519 DOT/1,000 patient days) prescribed in 173 infants during the study period, the most common indications were suspected EOS, followed by prophylaxis. Among the 85 DOT/1,000 patient days (PD; 38 courses) prescribed for prophylaxis, 52.5 DOT/1,000 PD (25 courses; 62%) were for surgical prophylaxis. Of 17 postoperative antibiotic courses, 15 (88.2%) were deemed to be inappropriate mostly due to a duration greater than 24 hours postoperatively (n = 13; median LOT = 3 days). CONCLUSION: Surgical prophylaxis is a common reason for antimicrobial misuse in outborn NICU. NICU-based prospective audit and feedback between neonatologists and antimicrobial stewardship teams alone may not be impactful in this setting. Partnerships with neonatologists and surgeons will be key to achieving the target of less than 24 hours of postoperative antimicrobials. KEY POINTS: · Surgical prophylaxis is a common reason for antimicrobial misuse in the NICU.. · Antimicrobial prophylaxis duration of less than 24 hours postoperatively should be encouraged.. · NICU-based prospective audit and feedback may not be impactful unless surgeons are involved..

INTRODUCTION: Eosinophilic esophagitis (EoE) is histologically defined as the presence of 15 or more intraepithelial eosinophils per high-power fields. Limited consensus exists on where to sample the esophagus in pediatrics. This study aimed to identify whether endoscopic and histologic examination of the mid esophagus offers diagnostic value compared to proximal/distal esophageal biopsies. METHODS: A retrospective chart review of pediatric patients with EoE was performed. Endoscopic and histologic parameters were assessed at the initial and follow-up visits, and concordance between proximal/distal biopsy and mid biopsy was determined. RESULTS: A total of 100 patients with a mean age of 9.6 ± 4.07 years were included. Endoscopic parameters between proximal/distal and mid esophagus were concordant in 84% to 97% of patients (initial assessment) and in 80% to 97% of patients (at follow-up). Mid esophagus showed endoscopic abnormalities, which were absent at the proximal/distal esophagus in 1% to 5% of patients, as well as histologic abnormalities in 2% to 8% of patients overall at initial and follow-up examinations. CONCLUSIONS: We recommend continued endoscopic and histologic assessment of the proximal/distal biopsy; however, examination of the mid esophagus does offer small diagnostic value in our subset of patients. Future studies need to be conducted before conclusive recommendations supporting the use of mid-esophageal biopsies can be made.

Anogenital distance (AGD) has been used as a marker of fetal androgen action to identify endocrine disrupting chemicals. A US study (TIDES) has reported that the association between some phthalates and reduced AGD in males was only apparent in sons of mothers reporting no stressful life events (SLEs) during pregnancy. The objective of the current study was to examine the potential modifying effect of SLEs and their subjective impact on associations between prenatal phthalates and AGD. First trimester urines from the MIREC Study were analysed for phthalate metabolites and AGD was measured in neonates. Post-delivery, the women answered questions on SLEs during the pregnancy. Women reporting 1 or more SLEs during pregnancy were considered a "higher stressor" group, whereas women reporting no SLEs or who reported a SLE that was perceived as not at all stressful were considered a "lower stressor" group. Multivariable linear regression models were fit stratified by stressor group. Maternal stressor, AGD and phthalates results were available for 153 females and 147 males. A summary measure of androgen-disrupting phthalates (Σ AD) was associated with significantly longer AGDs in females from the higher stressor group. These effect sizes were increased when the perceived impact was restricted to moderately or very much stressful. In males, all phthalates were associated with longer anopenile distance (APD), regardless of stressor group; however, higher Σ AD was associated with significantly longer APD in the lower stressor group. In contrast to the TIDES study, we did not observe shorter AGDs in male infants prenatally exposed to di-(2-ethylhexyl) phthalates, regardless of maternal stressor level. In conclusion, we were unable to replicate the findings of the TIDES study, but did find some evidence that prenatal SLEs may modify associations between phthalates and female AGD. Further research with other populations and measures of prenatal stress may shed more light on whether prenatal stress is an important effect modifier of associations between phthalates (or other chemicals) and anogenital distance.

BACKGROUND: Antimicrobial stewardship programs potentially lead to appropriate antibiotic use, yet the optimal approach for neonates is uncertain. Such a program was implemented in a tertiary care neonatal intensive care unit in October 2012. We evaluated the impact of this program on antimicrobial use and its association with clinical outcomes. METHODS: In a retrospective cohort study, we examined 1580 neonates who received antimicrobials in the 13-months before and 13-months during program implementation. Prospective audit and feedback was given 5 days a week on each patient who was receiving antibiotic. Pharmacy and microbiology data were linked to clinical data from the local Canadian Neonatal Network database. The primary outcome was days of antibiotic therapy per 1000 patient-days; secondary outcomes included mortality, necrotizing enterocolitis, and antibiotic duration for culture-positive and culture-negative late-onset sepsis. The breadth of antibiotic exposure was compared using the Antibiotic Spectrum Index. RESULTS: Overall antibiotic use decreased to 339 days of therapy per 1000 patient-days from 395 (14%, P < 0.001), without an increase in mortality. There was no difference in duration of therapy in culture-negative or culture-positive sepsis, rates of necrotizing enterocolitis, or breadth of antibiotic exposure. Fewer antibiotic starts occurred during program implementation (63% versus 59%, P < 0.001). The use of narrow-spectrum agents decreased (P < 0.001) whereas the use of cefotaxime increased (P = 0.016) during program implementation. CONCLUSIONS: Daily prospective audit and feedback was not associated with a change in antibiotic duration or clinical outcomes, however there were fewer babies started on antibiotics, suggesting that additional interventions are required to inform and sustain changes in antibiotic prescribing practices.

OBJECTIVE: To explore ethics education needs in Canadian Neonatal Perinatal Medicine (NPM) training programs. METHODS: A retrospective review of NPM trainees' performance at the National NPM Objective Structured Clinical Examination (OSCE) was undertaken for 2012 to 2017 and two distinct cross-sectional online surveys were carried out. One survey targeted recently graduated neonatologists (RGNs) who completed 2 years' training in a Canadian NPM program between 2010 and 2015; the other survey was sent to Canadian NPM training program directors (PDs). The domains of interest were: perception of education, ethics and communication topics, educational strategies, assessment of trainees' competencies, and barriers to neonatal ethics education. RESULTS: NPM trainees generally performed less well in stations involving ethics and communication relative to other domains on the National OSCE. Forty-seven RGNs (44.3%) and 12 PDs (92.3%) completed the survey. Over 90% of PDs and RGNs agreed on the importance of training in ethics and communication. Both groups highly valued training on topics related to communication. Preferred teaching strategies were experiential: observation and feedback. PDs mentioned the importance of using validated tools to regularly and formally assess trainees. They recognized challenges in regard to financial resources, physical space, and faculty training in patient-physician communication. CONCLUSIONS: National OSCE results indicate the need to improve neonatal ethics and communication training in Canadian NPM programs. RGNs and PDs identified important topics, as well as teaching and evaluation strategies. These results can be used to develop a training program for ethics and communication in NPM.
RESUMO
Background: Pediatric outcomes after flexor tendon repairs are variable, and evidence in the literature remains scarce. Methods: Repair of pediatric flexor tendon injuries was reviewed over a 10-year period (2005-2015). Data collection consisted of patient demographics, injury characteristics, anesthetic choice, repair technique, rehabilitation protocol, American Society for Surgery of the Hand Total Active Motion (TAM) scores, and complications. Results: There were 109 patients included in our study, with a total of 162 digits injured and 235 flexor tendon injuries. The mean age was 12 ± 4.6 years. The small finger (48 of 162; 30%) and the flexor digitorum profundus tendon (126 of 235) were the most commonly injured. The mechanism of injury was mainly from a knife (46 of 109; 42.2%) in zone II (82 of 159; 52%). Injuries were mostly repaired under general anesthetic (61 of 104; 56%). The Kessler technique was the predominant repair mechanism (111 of 225 repairs; 49%). Most patients (103 of 109; 95%) had excellent or good TAM scores with 5 postoperative ruptures reported. The most common complication was stiffness (17 of 121 complications; 14%), with most patients having no complications ( 74 of 109 patients; 68%). Patients were commonly immobilized (mean 8.4 ± 10.3 weeks) with a splint (93 of 109; 85%). There were 85 patients who followed a postoperative rehabilitation protocol for 12 ± 18 weeks. Patient demographics, time of repair, injury characteristics, anesthetic choice, and rehabilitation protocol were not significantly correlated with TAM scores or complication rates. Conclusions: Pediatric tendon injuries have good outcomes with no predictive factors identified. Surgical repairs performed under local anesthetic have similar outcomes without increased rates of complications, but remain underused in the pediatric population.

Introduction: Therapeutic hypothermia (TH) within 6 hours after birth is known to improve both survival and neurodevelopmental outcomes in neonates with hypoxic ischemic encephalopathy (HIE). Meeting this recommended target temperature for neonates who require transport for TH treatment can be complex for various reasons. This study aimed to reduce the time from birth to the initiation of TH and target temperature, thereby increasing the proportion of transported neonates reaching target temperature within 6 hours to >50%. Methods: We evaluated the effect of three quality improvement interventions, including revised transport team processes, outreach education/resources, and the use of a servo-controlled cooling device on land transports. We compared key outcome TH metrics for cohorts before and after implementation. Results: The study team compared baseline data for 77 to 102 neonates born between 2009 and April 2015 (preintervention) and September 2015 and September 2020 (postintervention(s)). We observed reductions in both the time from birth to the initiation of passive cooling (38%) and time to reach target TH temperature (23%), with an increase in the proportion of neonates reaching target temperature by 6 hours of age from 50% to 71%. Conclusions: We used quality improvement methodology to identify key areas for intervention(s) and improvement. Targeted interventions have successfully and consistently improved the timing and delivery of TH to neonates with hypoxic ischemic encephalopathy within the transport environment, with a 20% increase in neonates reaching target temperature by 6 hours of age.
RESUMO
Background: A variety of routine childhood and adolescent meningococcal vaccination programs using monovalent (serogroup C) and quadrivalent (A, C, Y, W) conjugate vaccines have been implemented in Canada since 2002, resulting in a decrease in invasive meningococcal disease (IMD) incidence, particularly in serogroup C. Meningococcal vaccines have also been used for outbreak response, including the multicomponent vaccine serogroup B vaccine. This report describes the epidemiology of IMD in Canada from 2012 to 2019. Methods: Case data were obtained from the National Enhanced IMD Surveillance System between January 1, 2012 and December 31, 2019. Isolates were sent to the National Microbiology Laboratory for confirmation of serogroup and further studies including phenotype and clonal complex identification. Results: A total of 983 cases of IMD were reported between 2012 and 2019. Overall, the age-adjusted incidence of IMD from 2012 to 2019 was 0.34 cases per 100,000 population per year when standardized to the Canadian 2011 population age distribution (95% CI: 0.32-0.36). Infants younger than one year of age had the highest average age-specific incidence rate (3.6 cases per 100,000 population per year, 95% CI: 2.8-4.3). The highest age-adjusted incidence rate was associated with serogroup B (0.17 cases per 100, 000 population per year, 95% CI: 0.16-0.19). Prior to 2015, most invasive serogroup W isolates were identified as clonal complex 22 (ST-22 CC) and the increase in serogroup W in Canada in recent years has been associated with the replacement of the endemic ST-22 CC with the hyper-virulent ST-11 CC. Conclusion: Invasive meningococcal disease is a rare but severe infection in Canada that mostly affects the very young. Serogroup B continues to account for the greatest proportion of disease. Serogroup W associated with ST-11 CC is becoming a growing contributor of disease in all age groups not protected by serogroup W-containing vaccines.
RESUMO
Objective: To establish reference intervals (RIs) for fetal and neonatal small and large intestinal lengths. Methods: Linear measurements on small and large intestines were made upon postmortem examination of 131 preterm and term infants with gestational ages between 13 and 41 weeks. All cases were referred from the Eastern Ontario and Western Québec regions to a tertiary care hospital. Age and sex partitions were considered and RI limits were estimated. Results: Data consisted of 72 male (54.96%) and 59 female (45.04%) fetuses and neonates with mean gestational age of 25.6 weeks. Results showed that small and large intestinal lengths increased linearly with gestational age. RIs for small intestinal length (cm) of fetuses and neonates aged 13-20 weeks were (21.1, 122.4); of those aged 21-28 weeks were (57.7, 203.8); of those aged 29-36 weeks were (83.6, 337.1); and of those aged 37-41 weeks were (132.8, 406.4). RIs for large intestinal length (cm) of fetuses and neonates from the same four age groups were (5.1, 21.4), (12.7, 39.7), (32.4, 62.4), and (29.1, 82.2). Conclusions: Establishing accurate RIs for premature and term infants has clinical relevance for pathologists performing postmortem analysis and for surgeons planning postoperative management of patients. The results of this study reaffirm that fetal small and large intestinal lengths increase linearly with gestational age irrespective of sex. Future studies should aim to further investigate the role of possible confounders on growth of fetal intestinal length, including maternal factors such as age and substance use during pregnancy.
RESUMO
Background: Hand fractures and dislocations are common injuries in the pediatric population. This study aims to characterize the pediatric hand injuries that required closed reduction and identify those that required multiple reduction attempts. Methods: A retrospective cohort study was carried out in patients younger than 18 years of age with hand fractures or dislocations who underwent closed reduction in the emergency department (ED). Patients who ultimately required surgical reduction and fixation were not included. Results: Of the 310 hand injuries identified, 148 (114 fractures and 34 dislocations) underwent closed reduction in the ED; 7.4% of those required repeat reduction. Hand injuries that most often required repeat reduction included metacarpophalangeal joint dislocations (20.0%) and proximal phalanx neck (16.7%), metacarpal shaft (15.4%), metacarpal neck (6.2%), and proximal phalanx base (5.6%) fractures. No modifiable risk factors predicting the need for repeat reduction were identified. Conclusions: Some pediatric hand injuries are more likely to require repeat closed reduction by a hand surgeon. This retrospective study is the first step toward quality improvement as it provides opportunities for further research into the factors contributing to reductions that are unsuccessful at the first attempt. Identification of these factors and implementation of quality improvement measures are necessary to ensure the effective treatment of all pediatric hand injuries.

Importance: There is low level of evidence and substantial practice variation regarding the use of intermittent or continuous monitoring in infants hospitalized with bronchiolitis. Objective: To compare the effect of intermittent vs continuous pulse oximetry on clinical outcomes. Design, Setting, and Participants: This multicenter, pragmatic randomized clinical trial included infants 4 weeks to 24 months of age who were hospitalized with bronchiolitis from November 1, 2016, to May 31, 2019, with or without supplemental oxygen after stabilization at community and children's hospitals in Ontario, Canada. Interventions: Intermittent (every 4 hours, n = 114) or continuous (n = 115) pulse oximetry, using an oxygen saturation target of 90% or higher. Main Outcomes and Measures: The primary outcome was length of hospital stay from randomization to discharge. Secondary outcomes included length of stay from inpatient unit admission to discharge and outcomes measured from randomization: medical interventions, safety (intensive care unit transfer and revisits), parent anxiety and workdays missed, and nursing satisfaction. Results: Among 229 infants enrolled (median [IQR] age, 4.0 [2.2-8.5] months; 136 [59.4%] male; 101 [44.1%] from community hospital sites), the median length of hospital stay from randomization to discharge was 27.6 hours (interquartile range [IQR], 18.8-49.6 hours) in the intermittent group and 25.4 hours (IQR, 18.3-47.6 hours) in the continuous group (difference of medians, 2.2 hours; 95% CI, -1.9 to 6.3 hours; P = .17). No significant differences were observed between the intermittent and continuous groups in the median length of stay from inpatient unit admission to discharge: 49.1 (IQR, 37.2-87.0) hours vs 46.0 (IQR, 32.5-73.8) hours (P = .13) or in frequencies or durations of hospital interventions, such as oxygen supplementation initiation: 4 of 114 (3.5%) vs. 9 of 115 (7.8%) (P = .16) and median duration of oxygen supplementation: 20.6 (IQR, 7.6-46.1) hours vs. 21.4 (11.6-52.9) hours (P = .66). Similarly, there were no significant differences in frequencies of intensive care unit transfer: 1 of 114 (0.9%) vs 2 of 115 (2.7%) (P = .76); readmission to hospital: 3 of 114 (2.6%) in the intermittent group vs 4 of 115 (3.5%) in the continuous group (P > .99); parent anxiety: mean (SD) parent anxiety score, 2.9 (0.9) in the intermittent group vs 2.8 (0.9) in the continuous group (P = .40); or parent workdays missed: median workdays missed, 1.5 (IQR, 0.5-3.0) vs 1.5 (IQR, 0.5-2.5) (P = .36). Mean (SD) nursing satisfaction with monitoring was significantly greater in the intermittent group: 8.6 (1.7) vs 7.1 (2.8) of 10 workdays; the mean difference was 1.5 (95% CI, 0.9-2.2; P < .001). Conclusions and Relevance: In this randomized clinical trial, among infants hospitalized with stabilized bronchiolitis with and without hypoxia and managed using an oxygen saturation target of 90% or higher, clinical outcomes, including length of hospital stay and safety, were similar with intermittent vs continuous pulse oximetry. Nursing satisfaction was greater with intermittent monitoring. Given that other important clinical practice considerations favor less intense monitoring, these findings support the standard use of intermittent pulse oximetry in stable infants hospitalized with bronchiolitis. Trial Registration: ClinicalTrials.gov Identifier: NCT02947204.

OBJECTIVES: Our objective was to examine the performance characteristics of a bladder stimulation technique for urine collection among infants presenting to the emergency department (ED). METHODS: This prospective cohort study enrolled a convenience sample of infants aged ≤ 90 days requiring urine testing in the ED. Infants were excluded if critically ill, moderately to severely dehydrated, or having significant feeding issues. Bladder stimulation consisted of finger tapping on the lower abdomen with or without lower back massage while holding the child upright. The primary outcome was successful midstream urine collection within 5 minutes of stimulation. Secondary outcomes included sample contamination, bladder stimulation time for successful urine collection, and perceived patient distress on a 100-mm visual analog scale (VAS). RESULTS: We enrolled 151 infants and included 147 in the analysis. Median age was 53 days (interquartile range [IQR] 27-68 days). Midstream urine sample collection using bladder stimulation was successful in 78 infants (53.1%; 95% confidence interval [CI] 45-60.9). Thirty-nine samples (50%) were contaminated. Most contaminated samples (n = 31; 79.5%) were reported as "no significant growth" or "growth of 3 or more organisms". Median bladder stimulation time required for midstream urine collection was 45 seconds (IQR 20-120 seconds). Mean VAS for infant distress was 22 mm (standard deviation 23 mm). CONCLUSIONS: The success rate of this bladder stimulation technique was lower than previously reported. The contamination rate was high, however most contaminated specimens were easily identified and had no clinical impact.

Canadian Inuit infants suffer the highest rate of lower respiratory tract infections (LRTI's) in the world. The causes of this are incompletely understood. The primary objective of this study was to determine whether there exists an association between respiratory morbidity and oral aspiration in Inuit children. A retrospective chart review was conducted including children from Nunavut who underwent Video Fluoroscopic Swallowing Study between the years of 2001 to 2015. The primary outcome was hospitalization for LRTI. We hypothesized that infants found to have aspiration would experience a higher rate of admissions for LRTI than those with normal swallowing studies. One-hundred and twenty-seven patients were identified, of whom 94 were included. Fifty-six percent of patients had an abnormal swallowing study. Compared with patients with normal swallowing, the incidence rate of LRTI was higher in patients with aspiration (incidence rate ratio [IRR] = 1.51; 95% confidence interval [CI] = 1.23-1.87) and in patients with penetration (IRR = 1.40; 95% CI = 1.11-1.76). Fourteen percent of patients had confirmed laryngeal cleft; patients with confirmed presence of this also had a higher incidence rate of LRTI (IRR = 1.66; 95% CI = 1.32-2.07). The incidence of abnormal swallowing study showed an 11-fold variation across the five regions in Nunavut, with the highest prevalence in west Qikiqtani Region (Baffin Island). We conclude that swallowing dysfunction is not only prevalent amongst Canadian Inuit but clinically significant. This is the first study to demonstrate an association between swallowing dysfunction and respiratory morbidity in this population. Geographic distribution patterns and high rates of laryngeal cleft may point to a potential genetic etiology for what remains at this point, idiopathic swallowing dysfunction.

This article was migrated. The article was marked as recommended. Objective: To evaluate the SAGE program five years following implementation. Methods: Our program evaluation was based on Guskey's five-level framework for evaluation of professional development. Residents and supervisors were invited to participate. Participants' reactions, learning, perceived organization support, use of new knowledge or skills and learning outcomes were examined through questionnaires and interviews. Results: 54% of residents and 65% supervisors were mostly or very satisfied with SAGE. 75% of residents felt there was moderate or great institutional support of resident research. Most residents and supervisors reported satisfaction with institutional research resources. Residents participating in the SAGE program reported a greater number of grant submissions and awards, but fewer conference presentations. Conclusions: SAGE has been well received by residents and supervisors. Findings suggest the program has fostered the development of research abilities and improved institutional support. It remains unclear if demonstrable learning outcomes have increased since program implementation. We also identified several barriers which will serve as targets for program improvement in future.
RESUMO
BACKGROUND: Anogenital distance (AGD) and the second to fourth finger (2D:4D) digit ratio may be early markers of in utero androgen exposure for the infant. Phthalates and phenols have been identified as endocrine disrupting chemicals. OBJECTIVES: To study the association between prenatal exposure to phthalates, bisphenol A (BPA) and triclosan (TCS) and AGD and the 2D:4D digit ratios. METHODS: Single spot urine samples were collected in the first trimester from the MIREC Study and analyzed for phthalates and phenols. Anogenital distance (nâ¯=â¯394) at birth and 2D:4D digit ratios (nâ¯=â¯420) at 6â¯months were measured in male and female infants. Associations between maternal concentrations of phenols and phthalate metabolites and these outcomes were estimated using multiple linear regression models. RESULTS: In females, the anoclitoris distance (ACD) was negatively associated with mono-benzyl phthalate (MBzP) (ßâ¯=â¯-1.24; 95% CI -1.91, -0.57) and positively associated with mono-ethyl phthalate (MEP) (ßâ¯=â¯0.65; 95% CI 0.12, 1.18) (masculinizing). In males, anopenile distance (APD) was positively associated with mono-n-butyl phthalate (MnBP) (ßâ¯=â¯1.17; 95% CI 0.02, 2.32) and the molar sum of low molecular weight phthalates (ΣLMW). Female 2D:4D of the right hand was positively associated with MnBP and negatively with total BPA (masculinizing). CONCLUSIONS: Significant associations were only observed for the long AGD metrics. Positive associations were observed between MnBP or LMW phthalates and APD in males. In females, prenatal MEP was associated with a masculinizing effect on ACD, while MBzP was associated with a feminizing effect. No significant associations were observed between prenatal phenols and AGD. Given the paucity of research on digit ratios and prenatal chemical exposures, it is difficult to say whether this metric will be a useful marker of prenatal androgen or anti-androgen exposure. Given the large number of associations examined, the statistical associations observed may have been due to Type 1 error. The inconsistencies in results between studies suggest that this issue is yet to be resolved.
