In-Vitro Cell-Induced Corrosion by Macrophages on Cobalt-Chromium-Molybdenum Alloy.

BACKGROUND: Patients have received cobalt-chromium-molybdenum (CoCrMo) implants for their joint replacement for decades. There have been reports of inflammatory cell-induced corrosion (ICIC) of these implants from retrieval studies. The goal of this study is to see if we could recreate ICIC in vitro and whether electrocautery damage to alloy surfaces may hasten this process. METHODS: Murine macrophages were cultured on CoCr disks with and without damage from a monopolar electrocautery. Culture medium was replaced every 12 hours and supernatant was collected every 4 days. After 30 days, cells were removed, counted, and digested. The metal concentrations in the supernatant and within cells were assessed using inductively coupled plasma spectrometry for comparison. RESULTS: The Co supernatant concentration was higher in the undamaged disks with activated macrophages. Higher concentrations of Co and Mo were found in the supernatant of the undamaged disks vs the electrocautery (EC) corrosion damaged disks. There was a significantly higher intracellular Co and Mo concentration with activated cells on CoCrMo disks vs the control group and no difference compared to EC damaged disk group. Scanning electron microscopy displayed microscopic pitting on the surfaces exposed to macrophages without EC damage. CONCLUSION: We found that macrophages could reproduce findings of ICIC pits on the surface of CoCrMo alloy and that the addition of EC damage to the surface did not increase the process. The clinical significance of these findings should be further investigated to determine if this could explain a small number of poor total knee arthroplasty reported outcomes.

Disparities in the Prevalence of Excess Heart Age Among Women with a Recent Live Birth.

Background: Understanding and addressing cardiovascular disease (CVD) risk has implications for maternal and child health outcomes. Heart age, the modeled age of an individual's cardiovascular system based on risk level, and excess heart age, the difference between a person's heart age and chronological age, are alternative simplified ways to communicate CVD risk. Among women with a recent live birth, we predicted heart age, calculated prevalence of excess heart age (≥5 years), and examined factors associated with excess heart age. Materials and Methods: Data were analyzed in 2017 from 2009 to 2014 Pregnancy Risk Assessment Monitoring System (PRAMS). To calculate heart age we used maternal age, prepregnancy body mass index, systolic blood pressure, smoking status, and diabetic status. Weighted prevalence and prevalence ratios compared the likelihood of excess heart age across racial/ethnic groups by selected factors. Results: Prevalence of excess heart age was higher in non-Hispanic black women (11.8%) than non-Hispanic white women (7.3%, prevalence ratio [PR], 95% confidence interval [CI]: 1.62, 1.49-1.76) and Hispanic women (4.9%, PR, 95% CI: 2.39, 2.10-2.72). Prevalence of excess heart age was highest among women who were without health insurance, obese or overweight, engaged in physical activity less than thrice per week, or were smokers in the prepregnancy period. Among women with less than high school education, non-Hispanic black women had a higher prevalence of excess heart age than Hispanic women (PR, 95% CI: 4.01, 3.15-5.10). Conclusions: Excess heart age may be an important tool for decreasing disparities and encouraging CVD risk reduction among certain groups of women.

Comparison of Inflammatory Cell-Induced Corrosion and Electrocautery-Induced Damage of Total Knee Implants.

Recently, inflammatory cell-induced corrosion (ICIC), a unique type of damage, has been reported in cobalt-chromium (CoCr) implants, but the mechanism remains poorly understood and controversial because electrocautery damage has also been shown to produce similar findings. This study aimed to distinguish between these two damage mechanisms. Forty-one CoCr primary total knee arthroplasty specimens were collected at time of necropsy. After removal and cleaning, light microscopy was used to identify areas of ICIC-like damage scars. A CoCr knee implant was intentionally damaged by electrocautery from both Bovie and Aquamantys sources using a 3-second hover method with 3 different energy settings for comparison to necropsy findings. Average roughness (Ra), max peak-to-valley height (Rmax), kurtosis (Rk), and skewness (Rsk) measurements were collected to represent the topography on the damaged areas for the CoCr implants. Necropsy implants showed signs of ICIC in 7 of 41 implants (17%) examined. Fe/C ratios of the Bovie electrocautery-damaged knee implant were shown to be statistically higher than those of necropsy-retrieved implants. Median Ra measurements were statistically less (P = 0.008) for Bovie-damaged areas compared to ICIC-dam-aged areas on CoCr. Median Rmax and Ra measurements were statistically less (P = 0.012, P < 0.001, respectively) for Aquamantys-damaged areas compared to ICIC-damaged areas on CoCr. While the visual patterns seen in necropsy-retrieved implants appeared similar to those with the intentionally damaged CoCrMo implant, the contents of the corroded regions are unique. The difference in roughness found on ICIC-damaged and electrocautery-damaged regions also indicates examination of surface topography as another distinguishing feature between the two mechanisms.

Disparities in Preconception Health Indicators - Behavioral Risk Factor Surveillance System, 2013-2015, and Pregnancy Risk Assessment Monitoring System, 2013-2014.

PROBLEM/CONDITION: Preconception health is a broad term that encompasses the overall health of nonpregnant women during their reproductive years (defined here as aged 18-44 years). Improvement of both birth outcomes and the woman's health occurs when preconception health is optimized. Improving preconception health before and between pregnancies is critical for reducing maternal and infant mortality and pregnancy-related complications. The National Preconception Health and Health Care Initiative's Surveillance and Research work group suggests ten prioritized indicators that states can use to monitor programs or activities for improving the preconception health status of women of reproductive age. This report includes overall and stratified estimates for nine of these preconception health indicators. REPORTING PERIOD: 2013-2015. DESCRIPTION OF SYSTEMS: Survey data from two surveillance systems are included in this report. The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing state-based, landline and cellular telephone survey of noninstitutionalized adults in the United States aged ≥18 years that is conducted by state and territorial health departments. BRFSS is the main source of self-reported data for states on health risk behaviors, chronic health conditions, and preventive health services primarily related to chronic disease in the United States. The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing U.S. state- and population-based surveillance system administered collaboratively by CDC and state health departments. PRAMS is designed to monitor selected maternal behaviors, conditions, and experiences that occur before, during, and shortly after pregnancy that are self-reported by women who recently delivered a live-born infant. This report summarizes BRFSS and PRAMS data on nine of 10 prioritized preconception health indicators (i.e., depression, diabetes, hypertension, current cigarette smoking, normal weight, recommended physical activity, recent unwanted pregnancy, prepregnancy multivitamin use, and postpartum use of a most or moderately effective contraceptive method) for which the most recent data are available. BRFSS data from all 50 states and the District of Columbia were used for six preconception health indicators: depression, diabetes (excluded if occurring only during pregnancy or if limited to borderline/prediabetes conditions), hypertension (excluded if occurring only during pregnancy or if limited to borderline/prehypertension conditions), current cigarette smoking, normal weight, and recommended physical activity. PRAMS data from 30 states, the District of Columbia, and New York City were used for three preconception health indicators: recent unwanted pregnancy, prepregnancy multivitamin use, and postpartum use of a most or moderately effective contraceptive method by women or their husbands or partners (i.e., male or female sterilization, hormonal implant, intrauterine device, injectable contraceptive, oral contraceptive, hormonal patch, or vaginal ring). Heavy alcohol use during the 3 months before pregnancy also was included in the prioritized set of 10 indicators, but PRAMS data for each reporting area are not available until 2016 for that indicator. Therefore, estimates for heavy alcohol use are not included in this report. All BRFSS preconception health estimates are based on 2014-2015 data except two (hypertension and recommended physical activity are based on 2013 and 2015 data). All PRAMS preconception health estimates rely on 2013-2014 data. Prevalence estimates of indicators are reported for women aged 18-44 years overall, by age group, race-ethnicity, health insurance status, and reporting area. Chi-square tests were conducted to assess differences in indicators by age group, race/ethnicity, and insurance status. RESULTS: During 2013-2015, prevalence estimates of indicators representing risk factors were generally highest and prevalence estimates of health-promoting indicators were generally lowest among older women (35-44 years), non-Hispanic black women, uninsured women, and those residing in southern states. For example, prevalence of ever having been told by a health care provider that they had a depressive disorder was highest among women aged 35-44 years (23.1%) and lowest among women aged 18-24 years (19.2%). Prevalence of postpartum use of a most or moderately effective method of contraception was lowest among women aged 35-44 years (50.6%) and highest among younger women aged 18-24 years (64.9%). Self-reported prepregnancy multivitamin use and getting recommended levels of physical activity were lowest among non-Hispanic black women (21.6% and 42.8%, respectively) and highest among non-Hispanic white women (37.8% and 53.8%, respectively). Recent unwanted pregnancy was lowest among non-Hispanic white women and highest among non-Hispanic black women (5.0% and 11.6%, respectively). All but three indicators (diabetes, hypertension, and use of a most or moderately effective contraceptive method) varied by insurance status; for instance, prevalence of current cigarette smoking was higher among uninsured women (21.0%) compared with insured women (16.1%), and prevalence of normal weight was lower among women who were uninsured (38.6%), compared with women who were insured (46.1%). By reporting area, the range of women reporting ever having been told by a health care provider that they had diabetes was 5.0% (Alabama) to 1.9% (Utah), and women reporting ever having been told by a health care provider that they had hypertension ranged from 19.2% (Mississippi) to 7.0% (Minnesota). INTERPRETATION: Preconception health risk factors and health-promoting indicators varied by age group, race/ethnicity, insurance status, and reporting area. These disparities highlight subpopulations that might benefit most from interventions that improve preconception health. PUBLIC HEALTH ACTION: Eliminating disparities in preconception health can potentially reduce disparities in two of the leading causes of death in early and middle adulthood (i.e., heart disease and diabetes). Public health officials can use this information to provide a baseline against which to evaluate state efforts to improve preconception health.

Core state preconception health indicators - pregnancy risk assessment monitoring system and behavioral risk factor surveillance system, 2009.

PROBLEM/CONDITION: Promoting preconception health can potentially improve women's health and pregnancy outcomes. Evidence-based interventions exist to reduce many maternal behaviors and chronic conditions that are associated with adverse pregnancy outcomes such as tobacco use, alcohol use, inadequate folic acid intake, obesity, hypertension, and diabetes. The 2006 national recommendations to improve preconception health included monitoring improvements in preconception health by maximizing public health surveillance (CDC. Recommendations to improve preconception health and health care-United States: a report of the CDC/ATSDR Preconception Care Work Group and the Select Panel on Preconception Care. MMWR 2006;55[No. RR-6]). REPORTING PERIOD COVERED: 2009 for 38 indicators; 2008 for one indicator. DESCRIPTION OF SURVEILLANCE SYSTEMS: The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing state- and population-based surveillance system designed to monitor selected self-reported maternal behaviors, conditions, and experiences that occur shortly before, during, and after pregnancy among women who deliver live-born infants. The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing state-based telephone survey of noninstitutionalized adults aged ≥18 years in the United States that collects state-level data on health-related risk behaviors, chronic conditions, and preventive health services. This surveillance summary includes PRAMS data from 29 reporting areas (n = 40,388 respondents) and BRFSS data from 51 reporting areas (n = 62,875 respondents) for nonpregnant women of reproductive age (aged 18-44 years). To establish a comprehensive, nationally recognized set of indicators to be used for monitoring, evaluation, and response, a volunteer group of policy and program leaders and epidemiologists identified 45 core state preconception health indicators, of which 41 rely on PRAMS or BRFSS as data sources. This report includes 39 of the 41 core state preconception health indicators for which data are available through PRAMS or BRFSS. The two indicators from these data sources that are not described in this report are human immunodeficiency virus (HIV) testing within a year before the most recent pregnancy and heavy drinking on at least one occasion during the preceding month. Ten preconception health domains are examined: general health status and life satisfaction, social determinants of health, health care, reproductive health and family planning, tobacco and alcohol use, nutrition and physical activity, mental health, emotional and social support, chronic conditions, and infections. Weighted prevalence estimates and 95% confidence intervals (95% CIs)for 39 indicators are presented overall and for each reporting area and stratified by age group (18-24, 25-34, and 35-44 years) and women's race/ethnicity (non-Hispanic white, non-Hispanic black, non-Hispanic other, and Hispanic). RESULTS: This surveillance summary includes data for 39 of 41 indicators: 2009 data for 23 preconception health indicators that were monitored by PRAMS and 16 preconception health indicators that were monitored by BRFSS (one BRFSS indicator uses 2008 data). For two of the indicators that are included in this report (prepregnancy overweight or obesity and current overweight or obesity), separate measures of overweight and obesity were reported. All preconception health indicators varied by reporting area, and most indicators varied significantly by age group and race/ethnicity. Overall, 88.9% of women of reproductive age reported good, very good, or excellent general health status and life satisfaction (BRFSS). A high school/general equivalency diploma or higher education (social determinants of health domain) was reported by 94.7% of non-Hispanic white, 92.9% of non-Hispanic other, 91.1% of non-Hispanic black, and 70.9% of Hispanic women (BRFSS). Overall, health-care insurance coverage during the month before the most recent pregnancy (health-care domain) was 74.9% (PRAMS). A routine checkup during the preceding year was reported by 79.0% of non-Hispanic black, 65.1% of non-Hispanic white, 64.3% of other, and 63.0% of Hispanic women (BRFSS). Among women with a recent live birth (2-9 months since date of delivery), selected PRAMS results for the reproductive health and family planning, tobacco and alcohol use, and nutrition domains included several factors. Although 43% of women reported that their most recent pregnancy was unintended (unwanted or wanted to be pregnant later), approximately half (53%) of those who were not trying to get pregnant reported not using contraception at the time of conception. Smoking during the 3 months before pregnancy was reported by 25.1% of women, and drinking alcohol 3 months before pregnancy was reported by 54.2% of women. Daily use of a multivitamin, prenatal vitamin, or a folic acid supplement during the month before pregnancy was reported by 29.7% of women. Selected BRFSS results included indicators pertaining to the nutrition and physical activity, emotional and social support, and chronic conditions domains among women of reproductive age. Approximately one fourth (24.7%) of women were identified as being obese according to body mass index (BMI) on the basis of self-reported height and weight. Overall, 51.6% of women reported participation in recommended levels of physical activity per U.S. Department of Health and Human Services physical activity guidelines. Non-Hispanic whites reported the highest prevalence (85.0%) of having adequate emotional and social support, followed by other races/ethnicities (74.9%), Hispanics (70.5%), and non-Hispanic blacks (69.7%). Approximately 3.0% of persons reported ever being diagnosed with diabetes, and 10.2% of women reported ever being diagnosed with hypertension. INTERPRETATION: The findings in this report underscore opportunities for improving the preconception health of U.S. women. Preconception health and women's health can be improved by reducing unintended pregnancies, reducing risky behaviors (e.g., smoking and drinking) among women of reproductive age, and ensuring that chronic conditions are under control. Evidence-based interventions and clinical practice guidelines exist to address these risks and to improve pregnancy outcomes and women's health in general. The results also highlight the need to increase access to health care for all nonpregnant women of reproductive age and the need to encourage the use of essential preventive services for women, including preconception health services. In addition, system changes in community settings can alleviate health problems resulting from inadequate social and emotional support and environments that foster unhealthy lifestyles. Policy changes can promote health equity by encouraging environments that promote healthier options in nutrition and physical activity. Finally, variation in the preconception health status of women by age and race/ethnicity underscores the need for implementing and scaling up proven strategies to reduce persistent health disparities among those at highest risk. Ongoing surveillance and research in preconception health are needed to monitor the influence of improved health-care access and coverage on women's prepregnancy and interpregnancy health status, pregnancy and infant outcomes, and health disparities. PUBLIC HEALTH ACTION: Public health decision makers, program planners, researchers, and other key stakeholders can use the state-level PRAMS and BRFSS preconception health indicators to benchmark and monitor preconception health among women of reproductive age. These data also can be used to evaluate the effectiveness of preconception health state and national programs and to assess the need for new programs, program enhancements, and policies.

Trends in smoking before, during, and after pregnancy--Pregnancy Risk Assessment Monitoring System, United States, 40 sites, 2000-2010.

PROBLEM: Smoking during pregnancy increases the risk for complications such as fetal growth restriction, preterm delivery, and infant death. In 2002, 5%-8% of preterm deliveries, 13%-19% of term infants with growth restriction, 5%-7% of preterm-related deaths, and 23%-34% of deaths from sudden infant death syndrome were attributable to prenatal smoking in the United States. REPORTING PERIOD COVERED: 2000-2010. DESCRIPTION OF SYSTEM: The Pregnancy Risk Assessment Monitoring System (PRAMS) was initiated in 1987 and is an ongoing state- and population-based surveillance system designed to monitor selected maternal behaviors and experiences that occur before, during, and after pregnancy among females who deliver live-born infants in the United States. Self-reported questionnaire data are linked to selected birth certificate data and are weighted to represent all women delivering live infants in the state. Self-reported smoking data were obtained from the PRAMS questionnaire and birth certificates. This report provides data on trends (aggregated and site-specific estimates) in smoking before, during, and after pregnancy from 40 PRAMS sites during 2000-2010. RESULTS: For the majority of sites, smoking prevalence before, during, or after pregnancy did not change over time. During 2000-2010, smoking prevalence decreased in three sites (Minnesota, New York state, and Utah) for all three measures and in eight sites (Colorado, Illinois, New Jersey, New Mexico, New York City, Washington, Wisconsin and Wyoming) for one or two of the measures. Smoking prevalence increased for all three measures in three sites (Louisiana, Mississippi, and West Virginia); an increase in prevalence before pregnancy (only) occurred in Oklahoma, and an increase during and after pregnancy occurred in Maine. For a subgroup of 10 sites for which data were available for the entire 11-year study period (Alaska, Arkansas, Colorado, Hawaii, Maine, Nebraska, Oklahoma, Utah, Washington, and West Virginia), the prevalence of smoking before pregnancy remained unchanged, with approximately one in five women reporting smoking before pregnancy (23.6% in 2000 to 24.7% in 2010). The prevalence of smoking during pregnancy decreased (p = 0.04; linear trend assessed with logistic regression) from 13.3% in 2000 to 12.3% in 2010, and the prevalence of smoking after delivery decreased (p<0.01) from 18.6% in 2000 to 17.2% in 2010. INTERPRETATION: The results indicate that efforts to reduce smoking prevalence among female smokers before pregnancy have not been effective; however, tobacco-control efforts have been minimally effective in reducing smoking prevalence during and after pregnancy. Current tobacco-control efforts in most sites might be insufficient to reach national objectives related to reducing prevalence of smoking during pregnancy. PUBLIC HEALTH ACTION: States with no change in or increasing smoking prevalence before, during, and after pregnancy can help reduce prevalence through sustained and comprehensive tobacco-control efforts (e.g., mass media campaigns, coverage of tobacco cessation, 100% smoke-free policies, and tobacco excise taxes).

Self-assembly and bilayer-micelle transition of fatty acids studied by replica-exchange constant pH molecular dynamics.

Recent interest in the development of surfactant-based nanodelivery systems targeting tumor sites has sparked our curiosity in understanding the detailed mechanism of the self-assembly and phase transitions of pH-sensitive surfactants. Toward this goal, we applied a state-of-the-art simulation technique, continuous constant pH molecular dynamics (CpHMD) with the hybrid-solvent scheme and pH-based replica-exchange protocol, to study the de novo self-assembly of 30 and 40 lauric acids, a simple model titratable surfactant. We observed the formation of a gel-state bilayer at low and intermediate pH and a spherical micelle at high pH, with the phase transition starting at 20-30% ionization and being completed at 50%. The degree of cooperativity for the transition increases from the 30-mer to the 40-mer. The calculated apparent or bulk pKa value is 7.0 for the 30-mer and 7.5 for the 40-mer. Congruent with experiment, these data demonstrate that CpHMD is capable of accurately modeling large conformational transitions of surfactant systems while allowing the simultaneous proton titration of constituent molecules. We suggest that CpHMD simulations may become a useful tool in aiding in the design and development of pH-sensitive nanocarriers for a variety of biomedical and technological applications.

Discharge timing, outpatient follow-up, and home care of late-preterm and early-term infants.

OBJECTIVE: To compare the timing of hospital discharge, time to outpatient follow-up, and home care practices (breastfeeding initiation and continuation, tobacco smoke exposure, supine sleep position) for late-preterm (LPT; 34 0/7-36 6/7 weeks) and early-term (ET; 37 0/7-38/6/7 weeks) infants with term infants. METHODS: We analyzed 2000-2008 data from the Centers for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System. χ(2) Analyses were used to measure differences in maternal and infant characteristics, hospital discharge, outpatient care, and home care among LPT, ET, and term infants. We calculated adjusted risk ratios for the risk of adverse care outcomes among LPT and ET infants compared with term infants. RESULTS: In the adjusted analysis, LPT infants were less likely to be discharged early compared with term infants, whereas there was no difference for ET infants (risk ratio [RR; 95% confidence interval (CI)]: 0.65 [0.54-0.79]; 0.95 [0.88-1.02]). [corrected]. LPT and ET infants were more likely to have timely outpatient follow-up (1.07 [1.06-1.08]; 1.02 [1.02-1.03]), more likely to experience maternal tobacco smoke exposure (1.09 [1.05-1.14]; 1.08 [1.06-1.11]), less likely to be initially breastfed (0.95 [0.94-0.97]; 0.98 [0.97-0.98]), less likely to be breastfed for ≥10 weeks (0.88 [0.86-0.90]; 0.94 [0.93-0.96]), and less likely to be placed in a supine sleep position (0.95 [0.93-0.97]; 0.97 [0.96-0.98]). CONCLUSIONS: Given that LPT and ET infants bear an increased risk of morbidity and mortality, greater efforts are needed to ensure safe and healthy posthospitalization and home care practices for these vulnerable infants.

Nitric oxide coupling mediated by iron porphyrins: the N-N bond formation step is facilitated by electrons and a proton.

The coupling of two NO molecules catalyzed by iron porphyrins is of biological importance. We use density functional theory calculations to examine the factors that control the fundamental N-N bond formation step mediated by a single iron porphyrin. The presence of an axial Im ligand, extra electrons, and most importantly a proton, enhance the N-N bond formation step in our model.

Chronic diseases and related risk factors among low-income mothers.

The aim is to describe the burden of chronic disease and related risk factors among low-income women of reproductive age. We analyzed population-based data from the 2005-2006 Pregnancy Risk Assessment Monitoring System (PRAMS) for 14,990 women with a live birth in 7 states. We examined the prevalence of selected chronic diseases and related risk factors (preexisting diabetes, gestational diabetes, chronic hypertension, pregnancy-induced hypertension, obesity, smoking or binge drinking prior to pregnancy, smoking or excessive weight gain during pregnancy, and postpartum depressive symptoms) by Federal Poverty Level (FPL) (≤100% FPL; 101-250% FPL; >250% FPL). Approximately one-third of women were low-income (≤100% FPL), one-third were near-low-income (101-250% FPL), and one-third were higher-income (>250% FPL). Compared to higher-income women, low-income women were significantly more likely to smoke before or during pregnancy (34.2% vs. 14.4%, and 24.8% vs. 5.4%, respectively), be obese (22.2% vs. 16.0%), experience postpartum depressive symptoms (23.3% vs. 7.9%), have 3 or more chronic diseases and/or related risk factors (28.1% vs. 14.4%) and be uninsured before pregnancy (48.9% vs. 4.8%). Low-income women of reproductive age experienced a higher prevalence of selected chronic diseases and related risk factors. Enhancing services for these women in publicly-funded family planning clinics may help reduce disparities in pregnancy and long-term health outcomes in the poor.

Maternity care practices and breastfeeding experiences of women in different racial and ethnic groups: Pregnancy Risk Assessment and Monitoring System (PRAMS).

Research shows that maternity care practices are important to promoting breastfeeding in the early post partum period; however, little is known about the association between maternity care practices and breastfeeding among different racial and ethnic groups. We examined the association between maternity care practices and breastfeeding duration to ≥10 weeks overall and among various racial and ethnic groups using data from the Pregnancy Risk Assessment and Monitoring System (PRAMS). PRAMS is a state, population-based surveillance system that collects information on maternal behaviors. We used maternity care practices data from 11 states and New York City with response rates ≥70% from 2004 to 2006. Multiple maternity care practices were examined and the analysis adjusted for demographic characteristics, participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), lifestyle, and infant variables. The outcome variable for multivariable analysis was breastfeeding duration to <10 weeks or ≥10 weeks. PRAMS data show that 22.1% of women did not breastfeed, about 27.7% breastfed for <10 weeks and 50.2% breastfed for ≥10 weeks. Breastfeeding patterns varied with white and Hispanic women reporting highest breastfeeding initiation and duration prevalence. Overall, practices positively associated with ≥10 duration were: breastfeeding initiated within the first hour after birth (adjusted OR [AOR] = 1.29; 95% CI: 1.16-1.45); fed breast milk only (AOR = 2.40; 95% CI: 2.15-2.68); breastfed on demand (AOR = 1.23; 95% CI 1.08-1.40) and receiving telephone support (AOR = 1.20; 95% CI: 1.03-1.39). Maternity care practices associated with breastfeeding to ≥10 weeks varied across three racial/ethnic groups. One practice, that of giving newborns breast milk only, was positively associated with breastfeeding duration of ≥10 weeks across all three groups. Maternity care practices associated with breastfeeding continuation to ≥10 weeks varied by race/ethnicity. For example: breastfeeding within the first hour, baby given a pacifier, and assistance from hospital staff, were significantly associated with breastfeeding duration among black and white women and not Hispanics. The practice of breastfeeding on demand was significantly associated with breastfeeding to ≥10 weeks for black and Hispanic women and not for whites. Hospitals may want to examine the implementation of specific practices in relation to the cultural backgrounds of women to promote breastfeeding.

Associations between preconception counseling and maternal behaviors before and during pregnancy.

Preconception counseling (PCC) is a vital component of preconception care. Through counseling, providers educate and recommend strategies to improve health and birth outcomes for women of reproductive age. The objective of our analysis was to assess the associations between receipt of PCC and positive maternal behaviors before and during pregnancy. We analyzed 2004-2008 Pregnancy Risk Assessment Monitoring System data from Maine, New Jersey, Utah, and Vermont. Multivariable logistic regression was used to investigate the associations between receipt of PCC and prepregnancy daily multivitamin consumption, first-trimester entry into prenatal care, and cessation of smoking and drinking before pregnancy among women who smoked/drank in the 2 years preceding the survey, adjusting for a wide range of maternal characteristics. Overall, 32% of women reported receipt of PCC, with particularly low rates reported among women with an unintended pregnancy (14%) and no health insurance prior to pregnancy (14%). Receipt of PCC was associated with daily prepregnancy multivitamin consumption (adjusted odds ratio [AOR] = 4.4; 95% confidence interval [CI] = 4.0, 4.7), first-trimester entry into prenatal care for women with an intended pregnancy (AOR = 2.1; 95% CI = 1.8, 2.4), and drinking cessation before pregnancy among women who drank in the 2 years preceding the survey (AOR = 1.3; 95% CI = 1.2, 1.5). PCC was associated with positive maternal behaviors that increase the likelihood of a healthy woman, pregnancy, and infant. Unfortunately, less than one-third of women with a recent live birth reported receiving PCC. These data provide population-based evidence suggesting the value of PCC in the promotion of healthy maternal behaviors for women with intended or unintended pregnancies.

Mental illness surveillance among adults in the United States.

Mental illnesses account for a larger proportion of disability in developed countries than any other group of illnesses, including cancer and heart disease. In 2004, an estimated 25% of adults in the United States reported having a mental illness in the previous year. The economic cost of mental illness in the United States is substantial, approximately $300 billion in 2002. Population surveys and surveys of health-care use measure the occurrence of mental illness, associated risk behaviors (e.g., alcohol and drug abuse) and chronic conditions, and use of mental health-related care and clinical services. Population-based surveys and surveillance systems provide much of the evidence needed to guide effective mental health promotion, mental illness prevention, and treatment programs. This report summarizes data from selected CDC surveillance systems that measure the prevalence and impact of mental illness in the U.S. adult population. CDC surveillance systems provide several types of mental health information: estimates of the prevalence of diagnosed mental illness from self-report or recorded diagnosis, estimates of the prevalence of symptoms associated with mental illness, and estimates of the impact of mental illness on health and well-being. Data from the CDC 2005-2008 National Health and Nutrition Examination Survey indicate that 6.8% of adults had moderate to severe depression in the 2 weeks before completing the survey. State-specific data from the CDC 2006 Behavioral Risk Factor Surveillance System (BRFSS), the most recent BRFSS data available, indicate that the prevalence of moderate to severe depression was generally higher in southeastern states compared with other states. Two other CDC surveys on ambulatory care services, the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey, indicate that during 2007-2008, approximately 5% of ambulatory care visits involved patients with a diagnosis of a mental health disorder, and most of these were classified as depression, psychoses, or anxiety disorders. Future surveillance should pay particular attention to changes in the prevalence of depression both nationwide and at the state and county levels. In addition, national and state-level mental illness surveillance should measure a wider range of psychiatric conditions and should include anxiety disorders. Many mental illnesses can be managed successfully, and increasing access to and use of mental health treatment services could substantially reduce the associated morbidity.

Patterns of cigarette and smokeless tobacco use before, during, and after pregnancy among Alaska native and white women in Alaska, 2000-2003.

OBJECTIVE: To examine patterns of cigarette and smokeless tobacco use before, during, and after pregnancy among Alaska Native (AN) and white women living in Alaska. METHODS: We used data from the 2000-2003 population-based Pregnancy Risk Assessment Monitoring System to describe patterns of self-reported prenatal tobacco use among AN and white women. We used multiple variable logistic regression analysis to identify maternal factors associated with quitting and relapse. The final sample included 5,458 women. RESULTS: During 2000-2003, the prevalence of any tobacco use before pregnancy was twofold higher among AN women than among white women (60.0 vs. 27.5%), and the prevalence of any tobacco use during pregnancy and after pregnancy were each nearly threefold higher. Of the 25.8% (SE 0.9) of white women who smoked before pregnancy, 49.0% (SE 2.1) reported that they quit during pregnancy and of those, 41.1% (SE 2.9) relapsed postpartum. Of the 38.5% (SE 0.9) of AN women who smoked before pregnancy, 35.7% (SE 1.4) quit, and of those 57.0% (SE 2.4) relapsed. Of the 14.2% of AN women who chewed tobacco before pregnancy, 15.7% (SE 1.7) quit, and of those, 52.9% (SE 5.9) relapsed. CONCLUSION: During 2000-2003, the prevalence of tobacco use was two to three times higher among AN women than among white women before, during, and after pregnancy. In addition, AN women had lower quit rates and higher relapse rates than white women. Comprehensive, culturally appropriate tobacco control approaches targeting AN women are needed to increase cessation during pregnancy and to decrease relapse.

Prenatal cigarette smoking and smokeless tobacco use among Alaska native and white women in Alaska, 1996-2003.

OBJECTIVE: To examine trends in prenatal cigarette smoking and smokeless tobacco use among Alaska Native (AN) and white women in Alaska. METHODS: Using 1996-2003 data from the population-based Pregnancy Risk Assessment Monitoring System, we determined trends in self-reported prenatal tobacco use among AN and white women and used chi-square tests and multiple variable logistic regression analysis to identify maternal factors associated with prenatal tobacco use. RESULTS: Over the study period, prevalence of any tobacco use during pregnancy declined by 27% among AN women (from 55.8 to 40.9%) (P < 0.0001) and by 17% among white women (from 18.8 to 15.6%) (P < 0.0001). In 2003, among AN women the prevalence of self-reported smokeless tobacco use was 16.9%, cigarette smoking was 25.7%, and any tobacco use was 40.9%; corresponding values for white women were 0.4, 15.0, and 15.6%, respectively. Western Alaska had the highest prevalence of tobacco use. CONCLUSION: The prevalence of tobacco use decreased between 1996 and 2003, but remained higher among AN women than white women, especially for smokeless tobacco. Support for cessation interventions targeting pregnant women should be made a public health priority in Alaska.

Inpatient hysterectomy surveillance in the United States, 2000-2004.

OBJECTIVE: The objective of the study was to examine recent trends in hysterectomy rates and indications in the United States. STUDY DESIGN: Data on hysterectomy hospitalizations during 2000-2004 were obtained from the National Hospital Discharge Survey, an annual nationally representative survey of inpatient hospitalization records. RESULTS: The hysterectomy rate decreased slightly from 5.4 per 1000 in 2000 to 5.1 per 1000 in 2004 (P for trend < .05). The proportion of hysterectomies performed for uterine leiomyoma decreased from 44.2% in 2000 to 38.7% in 2004 (P for trend < .01). Concomitant bilateral oophorectomy accompanied 54% of hysterectomies; this proportion declined from 55.1% in 2000 to 49.5% in 2004 (P for trend < .001). CONCLUSIONS: Continued monitoring is needed to determine whether the observed trends persist and to evaluate impact on women's health. In the future, information on both inpatient and outpatient procedures may be important for hysterectomy surveillance.

Preconception and interconception health status of women who recently gave birth to a live-born infant--Pregnancy Risk Assessment Monitoring System (PRAMS), United States, 26 reporting areas, 2004.

PROBLEM/CONDITION: In 2006, CDC published recommendations to improve health and health care for women before pregnancy and between pregnancies (CDC. Recommendations to improve preconception health and health care--United States: a report of the CDC/ATSDR Preconception Care Work Group and the Select Panel on Preconception Care. MMWR 2006;55[No. RR-6]). The Pregnancy Risk Assessment Monitoring System (PRAMS) provides data concerning maternal behaviors, health conditions, and experiences for women in the United States who have delivered a live birth. REPORTING PERIOD COVERED: 2004. DESCRIPTION OF SYSTEM: PRAMS is an ongoing, state- and population-based surveillance system designed to monitor selected maternal behaviors and experiences that occur before, during, and after pregnancy among women who deliver live-born infants in selected states and cities in the United States. PRAMS employs a mixed mode data-collection methodology; up to three self-administered questionnaires are mailed to a sample of mothers, and nonresponders are followed up with telephone interviews. Self-reported survey data are linked to selected birth certificate data and weighted for sample design, nonresponse, and noncoverage to create annual PRAMS analysis data sets that can be used to produce statewide estimates of perinatal health behaviors and experiences among women delivering live infants. This report summarizes data from 26 PRAMS reporting areas that collected data during 2004 and that had achieved overall weighted response rates of > or =70% and had weighted data available by the time the analysis was conducted in January 2007. Data are reported on indicators regarding 18 behaviors and conditions that are relevant to preconception (i.e., prepregnancy) health and health care and 10 that are relevant to interconception (i.e., postpartum) health and health care. The number of questions that were administered varied by site; certain questions were not asked for all reporting areas. RESULTS: With respect to preconception maternal behaviors and experiences, mean overall prevalence was 23.2% for tobacco use, 50.1% for alcohol use, 35.1% for multivitamin use at least four times a week, 53.1% for nonuse of contraception among women who were not trying to become pregnant, 77.8% for ever having a dental visit before pregnancy, 30.3% for receiving prepregnancy health counseling, 3.6% for experiencing physical abuse, and 18.5% for experiencing at least four stressors before pregnancy. With respect to preconception maternal health conditions, mean overall prevalence was 13.2% for women being underweight (body mass index [BMI]: <19.8), 13.1% for being overweight (BMI: 26.0-29.0), and 21.9% for being obese (BMI: > or =29.0). Mean overall prevalence was 1.8% for having diabetes, 6.9% for asthma, 2.2% for hypertension, 1.2% for heart problems, and 10.2% for anemia. Among women with a previous live birth, the mean overall prevalence of having a previous low birth weight infant was 11.6% and of having a previous preterm infant was 11.9%. With respect to interconception maternal behaviors and experiences, mean overall prevalence was 17.9% for tobacco use, 85.1% for contraceptive use, 15.7% for having symptoms of depression, and 84.8% for having social support. Mean overall prevalence was 7.5% for the most recent infant being born low birth weight, 10.4% for having a recent preterm infant, 89.3% for having a check-up, 89.0% for receiving contraceptive use counseling, 30.4% for having a dental visit, and 48.6% for receiving services from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Results varied by maternal age, race/ethnicity, pregnancy intention, and health insurance status. For certain risk behaviors and health conditions, mean overall prevalence was higher among women aged <20 years, black women, women whose pregnancies were unintended, and women receiving Medicaid; however, no single subgroup was consistently at highest risk for all the indicators examined in this report. INTERPRETATION: PRAMS results varied among reporting areas. The prevalence estimates in the majority of reporting areas and for the majority of indicators suggest that a substantial number of women would benefit from preconception interventions to ensure that they enter pregnancy in optimal health. The results also demonstrate disparities among age and racial/ethnic subpopulations, especially with respect to prepregnancy medical conditions and access to health care both before conception and postpartum. Differences also exist in health behaviors between women who reported intended and unintended pregnancies. PUBLIC HEALTH ACTION: Maternal and child health programs can use PRAMS data to monitor improvements in maternal preconception and interconception behaviors and health status. The data presented in this report, which were collected before publication of CDC's recommendations to improve preconception health and health care in the United States, can be used as a baseline to monitor progress toward improvements in preconception and interconception health following publication of the recommendations. These data also can be used to identify specific groups at high risk that would benefit from targeted interventions and to plan and evaluate programs aimed at promoting positive maternal and infant health behaviors, experiences, and reproductive outcomes. In addition, the data can be used to inform policy decisions that affect the health of women and infants.

Monitoring progress toward achieving Maternal and Infant Healthy People 2010 objectives--19 states, Pregnancy Risk Assessment Monitoring System (PRAMS), 2000-2003.

PROBLEM/CONDITION: Certain modifiable maternal behaviors and experiences before, during, and after pregnancy are associated with adverse health outcomes for the mother and her infant (e.g., physical abuse, insufficient folic acid consumption, smoking during pregnancy, and improper infant sleep position). Information about these behaviors and experiences is needed to monitor trends in maternal and infant health, enhance understanding of the relation between maternal behaviors and infant health outcomes, plan and evaluate maternal and infant health programs, direct policy decisions, and monitor progress toward achieving the national Healthy People 2010 [HP 2010] objectives (US Department of Health and Human Services. Healthy people 2010. 2nd ed. With understanding and improving health and objectives for improving health [2 vols.]. Washington, DC: US Department of Health and Human Services; 2000). REPORTING PERIOD COVERED: 2000-2003. DESCRIPTION OF SYSTEM: The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing, state- and population-based surveillance system designed to monitor selected maternal behaviors and experiences that occur before, during, and after pregnancy among women who deliver live-born infants. PRAMS employs a mixed mode data-collection methodology; up to three self-administered surveys are mailed to a sample of mothers; nonresponders are followed up with telephone interviews. Self-reported survey data are linked to selected birth certificate data and weighted for sample design, nonresponse, and noncoverage to create annual PRAMS analysis data sets that can be used to produce statewide estimates of perinatal health behaviors and experiences among women delivering live infants. This report summarizes data for 2000-2003 from 19 states (Alabama, Alaska, Arkansas, Colorado, Florida, Hawaii, Illinois, Louisiana, Maine, Nebraska, New Mexico, New York, North Carolina, Ohio, Oklahoma, South Carolina, Utah, Washington, and West Virginia) that measured progress toward achieving HP 2010 objectives for eight perinatal indicators: 1) pregnancy intention, 2) multivitamin use, 3) physical abuse, 4) cigarette smoking during pregnancy, 5) cigarette smoking cessation, 6) drinking alcohol during pregnancy, 7) breastfeeding initiation, and 8) infant sleep position. RESULTS: In 2003, prevalence of intended pregnancy among women having a live birth ranged from 48.1% in Louisiana to 66.5% in Maine; during 2000-2003, no state experienced a statistically significant (p< or =0.05) increase in prevalence of intended pregnancy, and one state experienced a significant decrease. In 2003, prevalence of multivitamin use at least four times per week during the month before pregnancy ranged from 23.0% in Arkansas to 45.2% in Maine; during 2000-2003, multivitamin use increased significantly in three states (Illinois, North Carolina, and Utah). In 2003, prevalence of physical abuse by a husband or partner during the 12 months before pregnancy ranged from 2.2% in Maine to 7.6% in New Mexico; during 2000-2003, significant decreases were recorded in three states (Alaska, Hawaii, and Nebraska). In 2003, prevalence of abstinence from cigarette smoking during the last 3 months of pregnancy ranged from 72.5% in West Virginia to 96.1% in Utah; during 2000-2003, a significant increase was recorded in Utah. In 2003, prevalence of smoking cessation during pregnancy ranged from 30.2% in West Virginia to 65.8% in Utah; during 2000-2003, a significant increase was recorded in Utah. In 2003, prevalence of abstinence from alcohol during the last 3 months of pregnancy ranged from 91.3% in Colorado to 98.0% in Utah; during 2000-2003, abstinence increased significantly in Louisiana and Utah but decreased significantly in Florida and Nebraska. In 2003, prevalence of mothers who breastfed their babies in the early postpartum period ranged from 51.2% in Louisiana to 90.3% in Alaska; during 2000-2003, significant increases were recorded in six states (Arkansas, Illinois, Louisiana, Nebraska, North Carolina, and South Carolina). In 2003, prevalence of healthy full-term infants who were placed to sleep on their backs ranged from 50.0% in Arkansas to 78.7% in Washington; during 2000-2003, significant increases were recorded in eight states (Alaska, Colorado, Illinois, Louisiana, Maine, Nebraska, North Carolina, and West Virginia). In 2003, all 19 states achieved or exceeded the HP 2010 objective for smoking cessation during pregnancy, and 16 states achieved the HP 2010 objective for abstinence from alcohol during the last 3 months of pregnancy. In addition, nearly half of the states achieved the objectives for breastfeeding in the early postpartum period and infant back sleep position. However, no state achieved the HP 2010 objectives for intended pregnancy, multivitamin use before pregnancy, absence of physical abuse before pregnancy, or abstinence from smoking during pregnancy. INTERPRETATION: PRAMS data indicate variability among states regarding progress toward achieving HP 2010 objectives in the area of maternal and child health. More progress has been made in achieving objectives focused on the period during and after pregnancy (e.g., smoking cessation and proper infant sleep position); less progress has been made in achieving objectives related to behaviors and experiences in the preconception period (e.g., pregnancy intention and multivitamin use). PUBLIC HEALTH ACTION: State maternal and child health programs can use these state- and population-based data to monitor progress toward achieving HP 2010 objectives, identify indicators to target for intervention, and plan and evaluate programs that promote positive maternal and infant health behaviors, experiences, and outcomes. These data also can be used to guide policy decisions that could affect the health of mothers and infants.

Surveillance for disparities in maternal health-related behaviors--selected states, Pregnancy Risk Assessment Monitoring System (PRAMS), 2000-2001.

PROBLEM/CONDITION: Disparities in maternal and infant health have been observed among members of different racial and ethnic populations and persons of differing socioeconomic status. For the Healthy People 2010 objectives for maternal and child health to be achieved (US Department of Health and Human Services. Healthy People 2010. 2nd ed. With understanding and improving health and objectives for improving health [2 vols.]. Washington DC: US Department of Health and Human Services, 2000), the nature and extent of disparities in maternal behaviors that affect maternal or infant health should be understood. Identifying these disparities can assist public health authorities in developing policies and programs targeting persons at greatest risk for adverse health outcomes. REPORTING PERIOD COVERED: 2000-2001. DESCRIPTION OF THE SYSTEM: The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing state- and population-based surveillance system designed to monitor selected maternal behaviors and experiences that occur before, during, and after pregnancy among women who deliver live-born infants. PRAMS employs a mixed mode data-collection methodology; up to three self-administered surveys are mailed to a sample of mothers, and nonresponders are followed up with telephone interviews. Self-reported survey data are linked to selected birth certificate data and weighted for sample design, nonresponse, and noncoverage to create annual PRAMS analysis data sets that can be used to produce statewide estimates of different perinatal health behaviors and experiences among women delivering live infants in 31 states and New York City. This report summarizes data for 2000-2001 from eight states (Alabama, Colorado, Florida, Hawaii, Illinois, Maine, Nebraska, and North Carolina) on four behaviors (smoking during pregnancy, alcohol use during pregnancy, breastfeeding initiation, and use of the infant back sleep position) for which substantial health disparities have been identified previously. RESULTS: Although the prevalence of each behavior varied by state, consistent patterns were observed among the eight states by age, race, ethnicity, education, and income level. Overall, the prevalence of smoking during pregnancy ranged from 9.0% to 17.4%. Younger (aged <25 years) women, white women, American Indian women, non-Hispanic women (except in Hawaii), women with a high school education or less, and women with low incomes consistently reported the highest rates of smoking. Overall, the prevalence of alcohol use during pregnancy ranged from 3.4% to 9.9%. In seven states, women aged >35 years, non-Hispanic women, women with more than a high school education, and women with higher incomes reported the highest prevalence of alcohol use during pregnancy. Overall, the prevalence of breastfeeding initiation ranged from 54.8% to 89.6%. Younger women, black women, women with a high school education or less, and women with low incomes reported the lowest rates of breastfeeding initiation. The size of the black-white disparity in breastfeeding varied among states. Overall, use of the back sleep position for infants ranged from 49.7% to 74.8%. Use of the back sleep position was lowest among younger women, black women, women with lower levels of education, and women with low incomes. Ethnic differences in sleep position varied substantially by state. INTERPRETATION: PRAMS data can be used to identify racial, ethnic, and socioeconomic disparities in critical maternal health-related behaviors. Although similar general patterns by age, education, and income were observed in at least seven states, certain racial and ethnic disparities varied by state. Prevalence of the four behaviors among each population often varied by state, indicating the potential impact of state-specific policies and programs. PUBLIC HEALTH ACTION: States can use PRAMS data to identify populations at greatest risk for maternal behaviors that have negative consequences for maternal and infant health and to develop policies and plan programs that target populations at high risk.sk. Although prevalence data cannot be used to identify causes or interventions to improve health outcomes, they do indicate the magnitude of disparities and identify populations that should be targeted for intervention. This report indicates a need for wider targeting than is often done. The results from this report can aid state and national agencies in creating more effective public health policies and programs. The data described in this report should serve as a baseline that states can use to measure the impact of policies and programs on eliminating these health disparities.

Simultaneous analysis of host and pathogen interactions during an in vivo infection reveals local induction of host acute phase response proteins, a novel bacterial stress response, and evidence of a host-imposed metal ion limited environment.

A fundamental goal in the study of infections is to understand the dynamic interplay between host and pathogen; however, direct in vivo interrogation of this disease process via transcriptional profiling has been lacking. Here we describe the development and application of novel bacterial RNA amplification technology to simultaneously identify key elements of both host and pathogen responses in a murine infection model. On the bacterial side, we found induction of an unusual pattern of stress response genes, a response to host-induced metal ion limitation, and a failure to achieve stationary phase in vivo. On the mammalian side, we observed the surprising induction of several genes encoding acute phase response proteins including hepcidin, haptoglobin, complement C3 and metallothionein 1 at the site of infection, as well as other mediators of innate immunity. Thus, our results reveal host-pathogen cross-talk not predicted by previous in vitro analyses and provide the framework to eavesdrop on a broad array of host-pathogen interactions in vivo. As described here, the comprehensive examination of host-pathogen interactions during an infection is critical to the discovery of novel approaches for intervention not predicted by current models.
