Birth Defects Res 2022 114 (14) 805-811 During the Centers for Disease Control and Prevention's Zika Virus Response, birth defects surveillance programs adapted to monitor birth defects potentially related to Zika virus (ZIKV) infection during pregnancy. Pregnancy outcomes occurring during January 2016 to June 2017 in 22 U.S. states and territories were used to estimate the prevalence of those brain and eye defects potentially related to ZIKV. Jurisdictions were divided into three groups: areas with widespread ZIKV transmission, areas with limited local ZIKV transmission, and areas without local ZIKV transmission. Prevalence estimates for selected brain and eye defects and microcephaly per 10,000 live births were estimated. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated using Poisson regression for areas with widespread and limited ZIKV transmission compared with areas without local ZIKV transmission. Defects with significantly higher prevalence in areas of widespread transmission were pooled, and PRs were calculated by quarter, comparing subsequent quarters to the first quarter (January-March 2016). Nine defects had significantly higher prevalence in areas of widespread transmission. The highest PRs were seen in intracranial calcifications (PR = 12.6, 95% CI [7.4, 21.3]), chorioretinal abnormalities (12.5 [7.1, 22.3]), brainstem abnormalities (9.3 [4.7, 18.4]), and cerebral/cortical atrophy (6.7 [4.2, 10.8]). The PR of the nine pooled defects was significantly higher in three quarters in areas with widespread transmission. The largest difference in prevalence was observed for defects consistently reported in infants with congenital ZIKV infection. Birth defects surveillance programs could consider monitoring a subset of birth defects potentially related to ZIKV in pregnancy. |

MMWR Morb Mortal Wkly Rep 2020 69 (3) 67-71 Zika virus infection during pregnancy can cause congenital brain and eye abnormalities and is associated with neurodevelopmental abnormalities (1-3). In areas of the United States that experienced local Zika virus transmission, the prevalence of birth defects potentially related to Zika virus infection during pregnancy increased in the second half of 2016 compared with the first half (4). To update the previous report, CDC analyzed population-based surveillance data from 22 states and territories to estimate the prevalence of birth defects potentially related to Zika virus infection, regardless of laboratory evidence of or exposure to Zika virus, among pregnancies completed during January 1, 2016-June 30, 2017. Jurisdictions were categorized as those 1) with widespread local transmission of Zika virus; 2) with limited local transmission of Zika virus; and 3) without local transmission of Zika virus. Among 2,004,630 live births, 3,359 infants and fetuses with birth defects potentially related to Zika virus infection during pregnancy were identified (1.7 per 1,000 live births, 95% confidence interval [CI] = 1.6-1.7). In areas with widespread local Zika virus transmission, the prevalence of birth defects potentially related to Zika virus infection during pregnancy was significantly higher during the quarters comprising July 2016-March 2017 (July-September 2016 = 3.0; October-December 2016 = 4.0; and January-March 2017 = 5.6 per 1,000 live births) compared with the reference period (January-March 2016) (1.3 per 1,000). These findings suggest a fourfold increase (prevalence ratio [PR] = 4.1, 95% CI = 2.1-8.4) in birth defects potentially related to Zika virus in widespread local transmission areas during January-March 2017 compared with that during January-March 2016, with the highest prevalence (7.0 per 1,000 live births) in February 2017. Population-based birth defects surveillance is critical for identifying infants and fetuses with birth defects potentially related to Zika virus regardless of whether Zika virus testing was conducted, especially given the high prevalence of asymptomatic disease. These data can be used to inform follow-up care and services as well as strengthen surveillance. |

Nolen LD , Vindigni SM , Parsonnet J , Bruce MG , Martinson HA , Thomas TK , Sacco F , Nash S , Olnes MJ , Miernyk K , Bruden D , Ramaswamy M , McMahon B , Goodman KJ , Bass AJ , Hur C , Inoue M , Camargo MC , Cho SJ , Parnell K , Allen E , Woods T , Melkonian S . Gastroenterology 2019 158 (5) 1197-1201 Alaska Native (AN) people experience higher incidence of, and mortality from, gastric cancer compared to other U.S. populations(1, 2). Compared to the general U.S. population, gastric cancer in AN people occurs at a younger age, is diagnosed at later stages, is more evenly distributed between the sexes, and is more frequently signet-ring or diffuse histology(3). It is known that the prevalence of Helicobacter pylori (Hp) infection, a risk factor for gastric cancer, is high in AN people(4); however, high antimicrobial resistance combined with high reinfection rates in Alaska make treatment at the population level complex(5). In addition, health issues in AN people are uniquely challenging due to the extremely remote locations of many residents. A multiagency workgroup hosted a symposium in Anchorage that brought internationally-recognized experts and local leaders together to evaluate issues around gastric cancer in the AN population. The overall goal of this symposium was to identify the best strategies to combat gastric cancer in the AN population through prevention and early diagnosis. |
National population-based estimates for major birth defects, 2010-2014
Mai CT , Isenburg JL , Canfield MA , Meyer RE , Correa A , Alverson CJ , Lupo PJ , Riehle-Colarusso T , Cho SJ , Aggarwal D , Kirby RS . Birth Defects Res 2019 111 (18) 1420-1435 BACKGROUND: Using the National Birth Defects Prevention Network (NBDPN) annual data report, U.S. national prevalence estimates for major birth defects are developed based on birth cohort 2010-2014. METHODS: Data from 39 U.S. population-based birth defects surveillance programs (16 active case-finding, 10 passive case-finding with case confirmation, and 13 passive without case confirmation) were used to calculate pooled prevalence estimates for major defects by case-finding approach. Fourteen active case-finding programs including at least live birth and stillbirth pregnancy outcomes monitoring approximately one million births annually were used to develop national prevalence estimates, adjusted for maternal race/ethnicity (for all conditions examined) and maternal age (trisomies and gastroschisis). These calculations used a similar methodology to the previous estimates to examine changes over time. RESULTS: The adjusted national birth prevalence estimates per 10,000 live births ranged from 0.62 for interrupted aortic arch to 16.87 for clubfoot, and 19.93 for the 12 critical congenital heart defects combined. While the birth prevalence of most birth defects studied remained relatively stable over 15 years, an increasing prevalence was observed for gastroschisis and Down syndrome. Additionally, the prevalence for atrioventricular septal defect, tetralogy of Fallot, omphalocele, and trisomy 18 increased in this period compared to the previous periods. Active case-finding programs generally had higher prevalence rates for most defects examined, most notably for anencephaly, anophthalmia/microphthalmia, trisomy 13, and trisomy 18. CONCLUSION: National estimates of birth defects prevalence provide data for monitoring trends and understanding the impact of these conditions. Increasing prevalence rates observed for selected conditions warrant further examination. |
Gastroschisis trends and ecologic link to opioid prescription rates - United States, 2006-2015
Short TD , Stallings EB , Isenburg J , O'Leary LA , Yazdy MM , Bohm MK , Ethen M , Chen X , Tran T , Fox DJ , Fornoff J , Forestieri N , Ferrell E , Ramirez GM , Kim J , Shi J , Cho SJ , Duckett K , Nelson N , Zielke K , St John K , Martin B , Clark C , Huynh MP , Benusa C , Reefhuis J . MMWR Morb Mortal Wkly Rep 2019 68 (2) 31-36 Prevalence of gastroschisis, a serious birth defect of the abdominal wall resulting in some of the abdominal contents extending outside the body at birth, has been increasing worldwide (1,2). Gastroschisis requires surgical repair after birth and is associated with digestive and feeding complications during infancy, which can affect development. Recent data from 14 U.S. states indicated an increasing prevalence of gastroschisis from 1995 to 2012 (1). Young maternal age has been strongly associated with gastroschisis, but research suggests that risk factors such as smoking, genitourinary infections, and prescription opioid use also might be associated (3-5). Data from 20 population-based state surveillance programs were pooled and analyzed to assess age-specific gastroschisis prevalence during two 5-year periods, 2006-2010 and 2011-2015, and an ecologic approach was used to compare annual gastroschisis prevalence by annual opioid prescription rate categories. Gastroschisis prevalence increased only slightly (10%) from 2006-2010 to 2011-2015 (prevalence ratio = 1.1, 95% confidence interval [CI] = 1.0-1.1), with the highest prevalence among mothers aged <20 years. During 2006-2015, the prevalence of gastroschisis was 1.6 times higher in counties with high opioid prescription rates (5.1 per 10,000 live births; CI = 4.9-5.3) and 1.4 times higher where opioid prescription rates were medium (4.6 per 10,000 live births; CI = 4.4-4.8) compared with areas with low prescription rates (3.2 per 10,000 live births; CI = 3.1-3.4). Public health research is needed to understand factors contributing to the association between young maternal age and gastroschisis and assess the effect of prescription opioid use during pregnancy on this pregnancy outcome. |
Changes in respiratory and non-respiratory symptoms in occupants of a large office building over a period of moisture damage remediation attempts
Park JH , Cho SJ , White SK , Cox-Ganser JM . PLoS One 2018 13 (1) e0191165 There is limited information on the natural history of building occupants' health in relation to attempts to remediate moisture damage. We examined changes in respiratory and non-respiratory symptoms in 1,175 office building occupants over seven years with multiple remediation attempts. During each of four surveys, we categorized participants using a severity score: 0 = asymptomatic; 1 = mild, symptomatic in the last 12 months, but not frequently in the last 4 weeks; 2 = severe, symptomatic at least once weekly in the last 4 weeks. Building-related symptoms were defined as improving away from the building. We used random intercept models adjusted for demographics, smoking, building tenure, and microbial exposures to estimate temporal changes in the odds of building-related symptoms or severity scores independent of the effect of microbial exposures. Trend analyses of combined mild/severe symptoms showed no changes in the odds of respiratory symptoms but significant improvement in non-respiratory symptoms over time. Separate analyses showed increases in the odds of severe respiratory symptoms (odds ratio/year = 1.151.16, p-values<0.05) and severity scores (0.02/year, p-values<0.05) for wheezing and shortness of breath on exertion, due to worsening of participants in the mild symptom group. For non-respiratory symptoms, we found no changes in the odds of severe symptoms but improvement in severity scores (-0.04-0.01/year, p-values<0.05) and the odds for mild fever and chills, excessive fatigue, headache, and throat symptoms (0.65-0.79/year, p-values<0.05). Our study suggests that after the onset of respiratory and severe non-respiratory symptoms associated with dampness/mold, remediation efforts might not be effective in improving occupants' health. |
Population-based microcephaly surveillance in the United States, 2009 to 2013: An analysis of potential sources of variation
Cragan JD , Isenburg JL , Parker SE , Alverson CJ , Meyer RE , Stallings EB , Kirby RS , Lupo PJ , Liu JS , Seagroves A , Ethen MK , Cho SJ , Evans M , Liberman RF , Fornoff J , Browne ML , Rutkowski RE , Nance AE , Anderka M , Fox DJ , Steele A , Copeland G , Romitti PA , Mai CT . Birth Defects Res A Clin Mol Teratol 2016 106 (11) 972-982 BACKGROUND: Congenital microcephaly has been linked to maternal Zika virus infection. However, ascertaining infants diagnosed with microcephaly can be challenging. METHODS: Thirty birth defects surveillance programs provided data on infants diagnosed with microcephaly born 2009 to 2013. The pooled prevalence of microcephaly per 10,000 live births was estimated overall and by maternal/infant characteristics. Variation in prevalence was examined across case finding methods. Nine programs provided data on head circumference and conditions potentially contributing to microcephaly. RESULTS: The pooled prevalence of microcephaly was 8.7 per 10,000 live births. Median prevalence (per 10,000 live births) was similar among programs using active (6.7) and passive (6.6) methods; the interdecile range of prevalence estimates was wider among programs using passive methods for all race/ethnicity categories except Hispanic. Prevalence (per 10,000 live births) was lowest among non-Hispanic Whites (6.5) and highest among non-Hispanic Blacks and Hispanics (11.2 and 11.9, respectively); estimates followed a U-shaped distribution by maternal age with the highest prevalence among mothers <20 years (11.5) and ≥40 years (13.2). For gestational age and birth weight, the highest prevalence was among infants <32 weeks gestation and infants <1500 gm. Case definitions varied; 41.8% of cases had an HC ≥ the 10th percentile for sex and gestational age. CONCLUSION: Differences in methods, population distribution of maternal/infant characteristics, and case definitions for microcephaly can contribute to the wide range of observed prevalence estimates across individual birth defects surveillance programs. Addressing these factors in the setting of Zika virus infection can improve the quality of prevalence estimates. |
Observational scores of dampness and mold associated with measurements of microbial agents and moisture in three public schools
Cho SJ , Cox-Ganser JM , Park JH . Indoor Air 2015 26 (2) 168-78 We examined associations between observational dampness scores and measurements of microbial agents and moisture in three public schools. A dampness score was created for each room from 4-point-scale scores (0-3) of water damage, water stains, visible mold, moldy odor, and wetness for each of 8 room components (ceiling, walls, windows, floor, ventilation, furniture, floor trench, and pipes), when present. We created mixed microbial exposure indices (MMEIs) for each of 121 rooms by summing decile ranks of 8 analytes (total culturable fungi; total, Gram-negative, and Gram-positive culturable bacteria; ergosterol; (1-->3)-beta-D-glucan; muramic acid; and endotoxin) in floor dust. We found significant (p ≤ 0.01) linear associations between the dampness score and culturable bacteria (total, Gram-positive, and Gram-negative) and the MMEIs. Rooms with dampness scores greater than 0.25 (median) had significantly (p < 0.05) higher levels of most microbial agents, MMEIs, and relative moisture content than those with lower scores (≤ 0.25). Rooms with reported recent water leaks had significantly (p < 0.05) higher dampness scores than those with historical or no reported water leaks. This study suggests that observational assessment of dampness/mold using a standardized form may be valuable for identifying and documenting water damage and associated microbial contamination. |
Birth defects data from population-based birth defects surveillance programs in the United States, 2007 to 2011: highlighting orofacial clefts
Mai CT , Cassell CH , Meyer RE , Isenburg J , Canfield MA , Rickard R , Olney RS , Stallings EB , Beck M , Hashmi SS , Cho SJ , Kirby RS . Birth Defects Res A Clin Mol Teratol 2014 100 (11) 895-904 The National Birth Defects Prevention Network (NBDPN) published the first Congenital Malformations Surveillance Report in 1997 and has annually released a report since 2000 that contains state-specific population-based data on major birth defects and a directory describing data collection information for population-based birth defects surveillance programs in the United States. The birth defects in these reports have included conditions affecting major organs of the central nervous, eye, ear, cardiovascular, orofacial, gastrointestinal, genitourinary, and musculoskeletal systems, as well as other disorders, including trisomies and amniotic band sequence. | In 2014, the NBDPN released an updated list of major birth defects as part of its national standards development for birth defects surveillance. The criteria used to guide deliberations for inclusion on the reportable list were: (1) public health importance; (2) accuracy of diagnosis; (3) amenable to prevention/intervention; (4) state of knowledge; (5) structural malformations, diagnosed within the first year of life; and (6) ability to separate into syndromic/nonsyndromic. For example, the NBDPN list now includes all 12 critical congenital heart defects (CCHDs) that are primary and secondary targets of pulse oximetry screening as a result of the addition of CCHD to the U.S. Recommended Universal Screening Panel for newborns (Mahle et al., 2012). Other noncardiac conditions that were added include clubfoot, cloacal exstrophy, craniosynostosis, deletion 22q11.2, holoprosencephaly, small intestinal atresia/stenosis, and Turner syndrome. These additions were balanced with the removal of several conditions, including: amniotic bands, aniridia, congenital hip dislocation, epispadias, fetus or newborn affected by maternal alcohol use, Hirschsprung disease (congenital megacolon), hydrocephalus, microcephalus, patent ductus arterious, and pyloric stenosis. Additional modifications to the list resulted in the regrouping of some conditions. Upper and lower limb deficiencies were collapsed into all limb deficiencies, while cleft lip with or without cleft palate was separated into cleft lip alone and cleft lip with cleft palate. Finally, obstructive genitourinary defect was limited to just the reporting of congenital posterior urethral valves. Table 1 presents the new reported list of birth defects and their diagnostic codes (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM]; and Centers for Disease Control and Prevention/British Pediatric Association Classification of Diseases [CDC/BPA]). |
Evaluation of individual-based and group-based exposure estimation of microbial agents in health effects associated with a damp building
Cho SJ , Cox-Ganser JM , Kreiss K , Park JH . J Expo Sci Environ Epidemiol 2012 23 (4) 409-15 We evaluated attenuation in linear associations between microbial exposure and respiratory symptoms occurring when individual measurements of microbial agents were used for estimating employees' exposure compared with group means. Symptoms, which improved when away from the building (building-related, BR), and measurements of culturable fungi, ergosterol, and endotoxin in floor dust were obtained between 2001 and 2007 from four cross-sectional studies on occupants of a water-damaged building. We compared odds ratios from longitudinal health effect models using individual measurements at employees' workstations with those using floor (group) means. Estimated odds for BR respiratory symptoms in group-based analyses increased by 2 to 5 times compared with those from individual-based analyses for culturable fungi and ergosterol, although they were less precise. For endotoxin, we found substantially increased and significant odds in group-based analyses, while we found no associations in individual-based analyses for various symptoms. Our study suggested that the building floor was useful in constructing exposure groups for microbial agents in this water-damaged building for epidemiologic analysis. Our study showed that group-average exposure estimation provides less attenuated associations between exposures to microbial agents and health in damp indoor environments where measurement error and intrinsic temporal variability are often large.

Levels of microbial agents in floor dust during remediation of a water-damaged office building
Cho SJ , Park JH , Kreiss K , Cox-Ganser JM . Indoor Air 2011 21 (5) 417-26 We examined the effects of remediation on loads of culturable fungi in floor dust collected from a large water-damaged office building during 4 cross-sectional surveys (2002, 2004, 2005, and 2007, respectively). We created a binary remediation variable for each year for each sampled workstation using information on remediation associated with water damage obtained from building management and used generalized linear mixed-effects models. We found significantly lower levels of culturable total and hydrophilic fungi at remediated workstations than at non-remediated workstations in 2004 and 2005 after completion of major remediation. The remediation effect, however, disappeared in 2007. The fraction of hydrophilic to total fungal concentrations was lowest in 2004, increased in 2005 and was highest in 2007. Our results indicate that the 2003 remediation lowered dust indices of dampness temporarily, but remediation was incomplete, consistent with a building assessment report of water infiltration. This study demonstrates the utility of longitudinal evaluation of microbial indices during remediation of water damage in this building, in which elimination of sources of moisture was not fully addressed. Our findings indicate that the fraction of hydrophilic fungi derived from concentrations of fungal species may be a useful index for assessing the long-term effectiveness of remediation. |
