Foreign-born status and risk of gestational diabetes mellitus by years of residence in the United States.

To explore the association between acculturation among foreign-born (FB) women, gestational diabetes (GDM) and GDM-associated adverse birth outcomes, we conducted a retrospective cohort study of 34,696 singleton pregnancies from Houston, TX, between 2011 and 2022. FB women (n = 18,472) were categorized based on years of residence in US (0-5, 6-10, and > 10 years), while US-born women (n = 16,224) were the reference group. A modified Poisson regression model determined the association between acculturative level and GDM within the entire cohort and stratified by race/ethnicity. Compared to US-born women, FB women with 0-5 years [adjusted relative risk (RRadj.) 1.27, 95% confidence interval [CI] 1.14-1.42)], 6-10 years (RRadj. 1.89, 95%CI 1.68-2.11) and > 10 years in the US (RRadj. 1.85, 95%CI 1.69-2.03) had higher risk of GDM. Results were consistent for all racial/ethnic groups, although associations were not significant at 0-5 years. FB women had lower risk of other adverse pregnancy outcomes, except for preeclampsia with severe features at higher levels of acculturation. Results were similar among those with and without GDM. In conclusion, FB status increases risk of GDM among all racial/ethnic groups but is elevated with higher acculturation levels.

Evaluating the Impact of Fetal Sex on Gestational Diabetes Mellitus Following Interaction with Maternal Characteristics.

Fetal-sex-specific changes to placental immunity and metabolism occur in response to obesity. Few studies have determined if fetal sex interacts with maternal characteristics to alter risk of gestational diabetes mellitus (GDM). Among 43,727 singleton pregnancies, we examined the association between male fetal sex and GDM using log-binomial logistic regression to calculate relative risks (RR) and 95% confidence intervals (CI). Interactions were examined between fetal sex and maternal characteristics on the risk of GDM by calculating relative excess risk due to interaction. After adjusting for body mass index, race/ethnicity, maternal age, education, and gravidity, male fetal sex was not associated with GDM (RRadj. 0.95, 95% CI 0.93, 1.04). We found a positive interaction between male fetal sex and obesity (p = 0.04). Nonobese women with male fetuses were less likely to develop GDM, but in the presence of obesity, an opposite trend was observed. There was a positive interaction between male fetal sex and GDM on the risk of preterm delivery < 37-weeks gestation (p = 0.0006). In response to underlying maternal obesity, fetal sex may modify the risk of GDM. In addition, male fetal sex may increase the occurrence of preterm birth among women with GDM.

Hospitalizations Among Children and Youth With Autism in the United States: Frequency, Characteristics, and Costs.

National estimates of hospitalization diagnoses and costs were determined using the 2016 HCUP Kids' Inpatient Database. Children and youth with autism were hospitalized over 45,000 times at over $560 million in costs and 260,000 inpatient days. The most frequent principal diagnoses for hospitalizations of children and youth with autism were epilepsy, mental health conditions, pneumonia, asthma, and gastrointestinal disorders, which resulted in almost $200 million in costs and 150,000 inpatient days. Mental health diagnoses accounted for 24.8% of hospitalizations, an estimated $82 million in costs, and approximately 94,000 inpatient days. Children and youth with autism were more likely hospitalized for epilepsy, mental health diagnoses, and gastrointestinal disorders, and less likely for pneumonia and asthma compared to other children and youth.

Regulation of mitochondrial proteostasis by the proton gradient.

Mitochondria adapt to different energetic demands reshaping their proteome. Mitochondrial proteases are emerging as key regulators of these adaptive processes. Here, we use a multiproteomic approach to demonstrate the regulation of the m-AAA protease AFG3L2 by the mitochondrial proton gradient, coupling mitochondrial protein turnover to the energetic status of mitochondria. We identify TMBIM5 (previously also known as GHITM or MICS1) as a Ca2+ /H+ exchanger in the mitochondrial inner membrane, which binds to and inhibits the m-AAA protease. TMBIM5 ensures cell survival and respiration, allowing Ca2+ efflux from mitochondria and limiting mitochondrial hyperpolarization. Persistent hyperpolarization, however, triggers degradation of TMBIM5 and activation of the m-AAA protease. The m-AAA protease broadly remodels the mitochondrial proteome and mediates the proteolytic breakdown of respiratory complex I to confine ROS production and oxidative damage in hyperpolarized mitochondria. TMBIM5 thus integrates mitochondrial Ca2+ signaling and the energetic status of mitochondria with protein turnover rates to reshape the mitochondrial proteome and adjust the cellular metabolism.

Sexually transmitted infections and risk of hypertensive disorders of pregnancy.

Hypertensive disorders of pregnancy (HDP) result in maternal morbidity and mortality but are rarely examined in perinatal studies of sexually transmitted infections. We examined associations between common sexually transmitted infections and HDP among 38,026 singleton pregnancies. Log-binomial regression calculated relative risk (RRs) and 95% confidence intervals (CIs) for associations with gestational hypertension, preeclampsia with severe features, mild preeclampsia, and superimposed preeclampsia. All models were adjusted for insurance type, maternal age, race/ethnicity, and education. Additional adjustments resulted in similar effect estimates. Chlamydia was associated with preeclampsia with severe features (RRadj. 1.4, 95% CI 1.1, 1.9). Effect estimates differed when we examined first prenatal visit diagnosis only (RRadj. 1.3, 95% CI 0.9, 1.9) and persistent or recurrent infection (RRadj. 2.0, 95% CI 1.1, 3.4). For chlamydia (RRadj. 2.0, 95% CI 1.3, 2.9) and gonorrhea (RRadj. 3.0, 95% CI 1.1, 12.2), women without a documented treatment were more likely to have preeclampsia with severe features. Among a diverse perinatal population, sexually transmitted infections may be associated with preeclampsia with severe features. With the striking increasing rates of sexually transmitted infections, there is a need to revisit the burden in pregnant women and determine if there is a link between infections and hypertensive disorders of pregnancy.

Characteristics Associated With Consistent Handwashing and Satisfaction in the Workplace: A Pilot Survey of U.S. Workers.

BACKGROUND: This study seeks to determine what handwashing facilities are available to workers, predominantly in the manufacturing and service industries, to find out if their workplace has the appropriate resources to conduct proper handwashing and how that affects handwashing satisfaction. METHODS: This cross-sectional study surveyed U.S. adult workers (N = 241) on their workplace handwashing equipment and facilities. The associations between demographic characteristics, consistent handwashing, and handwashing satisfaction were evaluated using Fisher's exact test. FINDINGS: Eighty-eight percent of respondents reported consistent handwashing. Pulling a handle to exit the restroom was negatively associated with handwashing satisfaction (p = .004) and having difficulty with an automatic faucet or dispenser was negatively marginally significant in its association with handwashing consistency (p = .10). CONCLUSION/APPLICATIONS TO PRACTICE: Greater understanding of the available equipment in workplace restroom facilities and how to improve selection and use of that equipment may improve workers' handwashing experiences.

Disparities in Prenatal Sexually Transmitted Infections among a Diverse Population of Foreign-Born and US-Born Women.

This study examined association between foreign-born (FB) status and a sexually transmitted infection (STI) diagnosis of Chlamydia trachomatis, Neisseria gonorrhoeae, or syphilis among a cohort of expecting mothers, and stratified by race/ethnicity. As a secondary analysis, subsequent adverse birth outcomes following STIs were examined. We used data from a large perinatal database to conduct a retrospective cohort study of 37,211 singleton births. Logistic regression was used to determine the association between FB status and STIs. We adjusted for maternal demographics, prior complications, and chronic disease. As a secondary analysis, we examined the association between STIs, and adverse birth outcomes stratified by FB status. FB women had lower odds of STI diagnosis (ORadj 0.81, 95% CI 0.71-0.93); this was observed for each STI. Among Hispanic women, FB status did not reduce odds of STIs (ORadj 0.89, 95% CI 0.76-1.04). However, FB Black women had reduced odds of STIs (ORadj 0.53, 95% CI 0.36-0.79). Secondary analyses revealed that STIs increased odds of adverse birth outcomes among US-born Black women but not US-born Hispanic women. Among FB Black women, STIs increased odds of medically indicated preterm birth (ORadj 3.77, 95% CI 1.19-12.00) and preeclampsia (ORadj 2.35, 95% CI 1.02-5.42). This was not observed among FB Hispanic women. Previous studies suggest that FB women are less likely to have adverse birth outcomes; our study extends this observation to risk of prenatal STIs. However, FB status does not protect Black women against adverse birth outcomes following an STI.

Developing a Public Health Maternal and Child Health Training Program: Lessons Learned from Five Schools of Public Health.

Maternal and child health (MCH), as a core sub-field of public health, continues to be an essential area in which additional workforce development and investment are needed. Recent public health workforce assessments in the United States reveal there will be a significant number of vacancies in MCH public health positions in the near future, creating the need for a well-trained and skilled public health MCH workforce. In order to address this potential critical workforce gap, the U.S. Department of Health and Human Services, Health Resources and Services Administration's Maternal and Child Health Bureau initiated the Maternal and Child Health Public Health Catalyst Program in 2015 to support the creation of MCH training programs in accredited schools of public health that previously did not have a MCH concentration. This article details the accomplishments and lessons learned from the first five MCH Catalyst Program grantees: Drexel University; Florida International University; Rutgers, The State University of New Jersey; Texas A&M University; and the University at Albany.

Epidemiology Surveillance and Capacity Improvement: A Characterization of Texas, 2017.

OBJECTIVES: In response to increasing caseloads of foodborne illnesses and high consequence infectious disease investigations, the Texas Department of State Health Services (DSHS) requested funding from the Texas Legislature in 2013 and 2015 for a new state-funded epidemiologist (SFE) program. METHODS: Primary cross-sectional survey data were collected from 32 of 40 local health departments (LHDs) via an online instrument and analyzed to quantify roles, responsibilities, and training of epidemiologists in Texas in 2017 and compared to similar state health department assessments. RESULTS: Sixty-six percent of SFEs had epidemiology-specific training (eg, master's in public health) compared to 45% in state health department estimates. For LHDs included in this study, the mean number of epidemiologists per 100 000 was 0.73 in medium LHDs and 0.46 in large LHDs. SFE positions make up approximately 40% of the LHD epidemiology workforce of all sizes and 56% of medium-sized LHD epidemiology staff in Texas specifically. CONCLUSIONS: Through this program, DSHS increased epidemiology capacity almost twofold from 0.28 to 0.47 epidemiologists per 100 000 people. These findings suggest that capacity funding programs like this improve epidemiology capacity in local jurisdictions and should be considered in other regions to improve general public health preparedness and epidemiology capacity.

Factors Associated with Hurricane Evacuation: A Statistical Meta-Analysis of Studies, 1999-2018.

OBJECTIVE: Hurricane evacuation is one of the strategies employed by emergency management and other agencies to reduce morbidity and mortality associated with hurricanes. However, factors associated with residents' evacuation decision-making have been inconsistent. In this study, we conducted a statistical meta-analysis to identify factors associated with hurricane evacuation as well as moderators of the evacuation decision. METHODS: A systematic literature search identified 36 studies published between 1999 and 2018. Pooled estimates were calculated using random-effects models, and heterogeneity across studies was checked using both Q and I2 statistics. Meta-regression methods were used to identify moderators. Publication bias was assessed using both visual (funnel plots) and statistical methods. RESULTS: Mobile home residence, perception of risk, female sex, and Hispanic ethnicity were statistically associated with hurricane evacuation, while geographic region modified the relationship between Hispanic race and evacuation. CONCLUSIONS: Agencies responsible for preparedness may utilize these findings to identify specific population sub-groups for hurricane evacuation communication and other interventions. Future studies should consider statistical interactions and explore opportunities for research translation to emergency officials.

Changes to Timeliness and Completeness of Infectious Disease Reporting in Texas After Implementation of an Epidemiologic Capacity Program.

OBJECTIVES: The objective of this study was to characterize the changes in timeliness and completeness of disease case reporting in Texas in response to an increasing number of foodborne illnesses and high-consequence infectious disease investigations and the Texas Department of State Health Services' new state-funded epidemiologist (SFE) program. METHODS: We extracted electronic disease case reporting data on 42 conditions from 2012 through 2016 in all local health department (LHD) jurisdictions. We analyzed data on median time for processing reports and percentage of complete reports across time and between SFE and non-SFE jurisdictions using Mann-Whitney t tests and z scores. RESULTS: The median time of processing improved from 13 days to 10 days from 2012 to 2016, and the percentage of disease case reports that were complete improved from 19.6% to 27.7%. Most reports were for foodborne illnesses; both timeliness (11 to 7 days) and completeness (20.9% to 23.5%) improved for these reports. CONCLUSIONS: Disease reporting improvements in timeliness and completeness were associated with the SFE program and its enhancement of epidemiologic capacity. SFEs were shown to improve surveillance metrics in LHDs, even in jurisdictions with a high volume of case reports. Adding epidemiologist positions in LHDs produces a tangible outcome of improved disease surveillance.

Telomere Length and Preterm Birth in Pregnant Mexican-Origin Women.

OBJECTIVES: Despite the obstacles of limited education and employment opportunities-and the stress associated with immigration and pregnancy-Mexican immigrant women have low rates of preterm birth (PTB) compared to the US national average for all races and ethnicities. Stressors during pregnancy, and stressors associated with acculturation, may accelerate cellular aging manifested by shortened telomere length (TL) in pregnant women. Our objectives were to: (1) determine whether women with PTBs had shorter telomere lengths compared to women who had full term births; (2) assess the association of acculturation with TL and PTB. METHODS: This prospective pilot study collected data from 100 self-identified Mexican-origin pregnant women. Survey data included self-administered sociodemographic and acculturation measures and was collected from participants via paper and pen, while biologic data was collected via a single blood draw during a regularly scheduled prenatal visit between 26 and 36 weeks gestation. PTB data was collected from the participant's medical record after delivery. RESULTS: TL was significantly associated with PTB; the median TL of the women with PTB was less than the median TL for the full sample (p = 0.02). Based on regression analysis for PTB vs acculturation, we found no significant associations between acculturation and PTB or TL. CONCLUSIONS FOR PRACTICE: This study provides important evidence of the association between shortened maternal TL and adverse birth outcomes. By linking social, clinical and biologic data, we can enhance our understanding of social determinants that may affect racial and ethnic disparities in preterm birth.

The main objective of the present article is to report our experience of endovascular management of infectious arterial pseudoaneurysms (IAP).A retrospective and observational study, it includes patients with a diagnosis of infectious arterial pseudoaneurysms treated with endovascular procedures in our centre between June 2016 and June 2018.(AU)

Traumatic Brain Injury Related Hospitalizations: Factors Associated with In-hospital Mortality among Elderly Patients Hospitalized with a TBI.

Background: This study aims to describe TBI-related hospitalizations for the whole population and identify factors associated with in-hospital mortality among elderly (≥65 years) patients hospitalized with TBI in Texas.Methods: Using Texas Hospital Discharge Data from 2012 to 2014, TBI-related hospitalizations were identified using International Classification of Diseases - Ninth Revision - Clinical Modification (ICD-9-CM) codes. Rates for age and gender were estimated using U.S. Census data. Univariate and multivariate analyses were used to identify factors associated with in-hospital mortality among those aged at least 65 years.Results: There were 51,419 TBI-related hospitalizations from 2012 to 2014 in Texas. Falls were the leading cause of TBI-related hospitalizations 6235 (36.64%), 6595 (38.40%), and 5412 (37.59%) for 2012, 2013, and 2014, respectively. Males had higher rates of hospitalizations while rates were highest for those above 80 years of age. Compared to Whites, Hispanics had 1.18 higher adjusted odds of in-hospital mortality [OR = 1.18: 95% CI (1.01-1.40)]. Similarly, adjusted odds of in-hospital mortality were higher among males [OR = 1.55: 95% CI (1.36-1.77)].Conclusion: This study provided evidence of demographic disparities in the burden and outcome of TBI in Texas, findings could serve as a foundation for targeted TBI prevention interventions.

Religiosity, Acculturation, and Preterm Birth in Mexican-Origin Women: A Pilot Study.

INTRODUCTION: Explanations for racial disparities in preterm birth (PTB) are elusive, especially when comparing high rates in some racial groups with low rates in Mexican-immigrant women. The purpose of this study was to examine potential protective factors against PTB such as religiosity and acculturation. METHODS: This study was a prospective investigation of Mexican- and U.S.-born pregnant women. Women were recruited from a low-income-serving prenatal clinic in Texas. Survey instruments included socioeconomic variables, acculturation, and religiosity/spirituality (R/S). Logistic regression was used to examine the associations between acculturation, religiosity, and PTB. Because of the low prevalence of PTB in our sample, we were not able to adjust for confounding characteristics. RESULTS: Ninety-one low-income women, mostly Mexican immigrants, participated in the study. PTB in our sample was lower than the national average in the United States (5.5% vs. 9.9%) and was positively but moderately associated with high R/S. R/S scores were high, particularly for frequency of attendance, prayer, and religious coping. Women with lower acculturation had higher scores on the religiosity measures. CONCLUSION: Further research is needed with a larger sample to include other ethnic and racial minorities to more fully understand the relationships between acculturation, religiosity, and PTB.

The Impact of Natural Disasters on Suicide in the United States, 2003-2015.

Background: Natural disasters are increasing in frequency and severity and impacted populations develop mental health conditions at higher rates than those not impacted. Aims: In this study, we investigate the association between exposure to a major natural disaster and suicide in the US. Method: Using county-level data on disaster declarations, mortality files, and population data, suicide rates were estimated for three 12-month periods before and after the disaster. Pooled rates were estimated predisaster and compared with postdisaster suicide rates using Poisson-generated Z tests and 95% confidence intervals. Results: A total of 281 major disasters were included. The suicide rate increased for each type of disaster and across all disasters in the first 2 years of follow-up. The largest overall increases in suicide rates were seen 2 years postdisaster. Limitations: Limitations include the ecologic study design, county-level exposure, and low power. Conclusion: Increases in county-level suicide rates after disasters were not statistically significant, although there was evidence that increases were delayed until 2 years postdisaster. Additional studies are needed to improve understanding of nonfatal suicide attempts after disasters and the role elevated social support plays in suicide prevention postdisaster. Future studies should consider pre-existing mental health, secondary stressors, and proximity to hazards.

Chlamydia trachomatis Is Associated With Medically Indicated Preterm Birth and Preeclampsia in Young Pregnant Women.

BACKGROUND: Studies on Chlamydia trachomatis-associated pregnancy outcomes are largely conflicting, ignoring the heterogeneous natures of pregnancy complications and potential effect modification by maternal age. This study determined if prenatal C. trachomatis infection is associated with preterm birth (PTB) and preeclampsia subtypes. METHODS: A retrospective cohort study was conducted using 22,772 singleton pregnancies with a prenatal C. trachomatis diagnostic test. Spontaneous and medically indicated PTBs, and term and preterm preeclampsia were outcomes. Modified Poisson regression calculated relative risk (RR) and 95% confidence intervals (CI) with propensity score adjustments stratified by maternal ages <25 and ≥25 years. RESULTS: Overall, C. trachomatis was significantly associated with term preeclampsia (adjusted RR [RRadj], 1.88; 95% CI, 1.38-2.57). Among young women (age <25 years), C. trachomatis was significantly associated with medically indicated PTB (RRadj, 2.29; 95% CI, 1.38-3.78) and term preeclampsia (RRadj, 1.57; 95% CI, 1.05-2.36) in propensity-adjusted models. No significant associations in older women were detected. CONCLUSION: C. trachomatis was associated with medically indicated PTB and term preeclampsia in young women. Associations between chlamydia and perinatal outcomes may depend on the subtype of PTB and preeclampsia, which should be investigated through mechanistic studies.

Estimating Evacuation Shelter Deficits in the Houston-Galveston Metropolitan Area.

Evacuation is frequently used by emergency managers and other officials as part of an overall approach to reducing the morbidity and mortality associated with hurricane landfall. In this study, the evacuation shelter capacity of the Houston-Galveston Metropolitan Statistical Area (MSA) was spatially assessed and shelter deficits in the region were estimated. These data provide essential information needed to eliminate shelter deficits and ensure a successful evacuation from a future storm. Spatial statistical methods-Global Moran's I, Anselin Local Moran's I (Local Indicators of Spatial Association [LISA]), and Hot Spot Analysis (Getis-Ord Gi*) were used to assess for regional spatial autocorrelation and clustering of evacuation shelters in the Houston-Galveston MSA. Shelter deficits were estimated in four ways-the aggregate deficit for the Houston-Galveston MSA, by evacuation Zip-Zone, by county, and by distance or radii of evacuation Zip-Zone. Evacuation shelters were disproportionately distributed in the region, with lower capacity shelters clustered closer to evacuation Zip-Zones (50 miles from the Coastal Zip-Zone), and higher capacity shelters clustered farther away from the zones (120 miles from the Coastal Zip-Zone). The aggregate shelter deficit for the Houston-Galveston MSA was 353,713 persons. To reduce morbidity and mortality associated with future hurricanes in the Houston-Galveston MSA, authorities should consider the development and implementation of policies that would improve the evacuation shelter capacity of the region. Eliminating shelter deficits, which has been done successfully in the state of Florida, is an essential element of protecting the public from hurricane impacts.

How Do Infectious Disease Epidemiologist Positions Increase Public Health Capacity? Results from a Qualitative Study of Local Health Departments.

The purpose of this study was to characterize changes in and impacts on epidemiologic capacity in local health departments after the implementation of a state-funded epidemiologist program using qualitative data. The study used key informant interviews in Texas health departments, which were conducted and inductively analyzed to identify themes. Five predominant themes emerged from interviews on the impact of state-funded epidemiologists on the epidemiology capacity of local health departments. State-funded epidemiologists were seen as increasing overall epidemiology capacity in local health departments. Specifically, they improved timeliness of infectious disease reporting and quality and thoroughness of disease investigations. They also improved community stakeholder relationships with local health departments and communications across local, regional, and state public health agencies. Key informants at all levels described positive effects of the state-funded epidemiologists on disease surveillance. Local epidemiology capacity has increased, and, in turn, Texas public health surveillance capacity has improved at the local, regional, and state levels. Funding programs like this should be considered when public health capacity is low and in need of an increase.

High-mobility group box 1 at the time of parturition in women with gestational diabetes mellitus.

PROBLEM: High-mobility group box 1 (HMGB1), a danger-associated molecular pattern marker, may indicate sterile inflammation through innate immune pathways. HMGB1 is implicated in hyperglycemia and excess glucose in trophoblast. Metabolic dysfunction and dyslipidemia are associated with gestational diabetes mellitus (GDM), but few studies examined associations between HMGB1 and GDM. We determined HMGB1 levels, and the ratio of HMGB1 to innate immune markers, in women with GDM at parturition. METHOD OF STUDY: This case-control study of 50 GDM pregnancies and 100 healthy controls utilized data and plasma samples from PeriBank. HMGB1, pentraxin-3, and interleukin (IL)-6 were measured by ELISA. Logistic regression calculated odds ratios (OR) and 95% confidence intervals (CI) adjusting for age, pre-pregnancy body mass index, and type of labor. RESULTS: There were no significant associations between HMGB1 and GDM. The ratio of HMGB1 to pentraxin-3 and IL-6 did not alter the odds of GDM. There was a significant statistical interaction between HMGB1 and maternal age (P = .02). When associations were examined by age groups, HMGB1 was associated with reduced odds of HMGB1 among women ≤25 (AOR = 0.007 CI 95% <0.001-0.3). Odds ratios increased as age increased (AOR range 1.2-3.8) but results were not statistically significant. CONCLUSION: High-mobility group box 1 was not associated with GDM. However, we found evidence that maternal age was a potential effect modifier of the relationship between HMGB1 and GDM. As there is growing evidence that HMGB1 may play important roles in reproduction, future studies should explore maternal factors that may alter HMGB1 levels.
