RESUMO

OBJECTIVE: To describe vaginal microbiota classified by community state types (CST) in a diverse cohort of postmenopausal women and evaluate relationships among genitourinary syndrome of menopause (GSM) symptoms (vaginal dryness, vulvovaginal irritation, sexual pain, dysuria, urinary urgency), CSTs, estrogen, vaginal maturation index (VMI), and vaginal pH. METHODS: In the Study of Women's Health Across the Nation, 1,320 women aged 60.4 to 72.5 years self-collected (2015-2017) vaginal samples analyzed for microbiota composition and structure (CSTs) using 16S rRNA gene amplicon sequencing, VMI, and pH. GSM symptoms were collected with self-administered questionnaires; interviewers elicited estrogen use and measured body mass index. Serum E2 and E1 were measured using high-performance liquid chromatography. We analyzed data using Pearson χ2 tests, analysis of variance, Kruskal-Wallis tests, and binomial logistic regression. RESULTS: The most frequently occurring CST was low Lactobacillus species IV-C (49.8%); 36.4% of women had CSTs dominated by Lactobacillus species. More than half of the women with vaginal atrophy biomarkers (VMI <50 and pH >5) had CST IV-C0, whereas women using estrogen or with higher E1 and E2 levels had a higher prevalence of Lactobacillus crispatus -dominated CST I ( P values < 0.001). Sexual pain was associated with atrophy biomarkers and independently associated with Streptococcus species-dominated CST IV-C1 (odds ratio, 2.26; 95% confidence intervals, 1.20-4.23). For all other GSM symptoms, we found no consistent associations with E1 or E2 levels, atrophy biomarkers, or any CST. CONCLUSIONS: Although close relationships exist among estrogen, CSTs, VMI, and pH, sexual pain was the only GSM symptom associated with the structure of vaginal microbiota and atrophy biomarkers.

RESUMO

BACKGROUND: The menopause transition (MT) is linked to adverse changes in lipids/lipoproteins. However, the related contributions of anti-Müllerian hormone (AMH) and estradiol (E2) are not clear. OBJECTIVE: To evaluate the independent associations of premenopausal AMH and E2 levels and their changes with lipids/lipoproteins levels [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), apolipoprotein B (apoB) and apolipoprotein A-1 (apoA-1)] over the MT. METHODS: SWAN participants who transitioned to menopause without exogenous hormone use, hysterectomy, or bilateral oophorectomy with data available on both exposure and outcomes when they were premenopausal until the 1st visit postmenopausal were studied. RESULTS: The study included 1,440 women (baseline-age:mean±SD=47.4±2.6) with data available from up to 9 visits (1997-2013). Lower premenopausal levels and greater declines in AMH were independently associated with greater TC and HDL-C, whereas lower premenopausal levels and greater declines in E2 were independently associated with greater TG and apo B and lower HDL-C. Greater declines in AMH were independently associated with greater apoA-1, and greater declines in E2 were independently associated with greater TC and LDL-C. CONCLUSIONS: AMH and E2 and their changes over the MT relate differently to lipids/lipoproteins profile in women during midlife. Lower premenopausal and/or greater declines in E2 over the MT were associated with an atherogenic lipid/lipoprotein profile. On the other hand, lower premenopausal AMH and/or greater declines in AMH over the MT were linked to higher apo A-1 and HDL-C; the later found previously to be related to a greater atherosclerotic risk after menopause.

RESUMO

INTRODUCTION/PURPOSE: Research is needed to inform tailoring supportive strategies for promoting physical activity (PA) in the context of behavioral treatment of obesity. We aimed to identify baseline participant characteristics and short-term intervention response predictors associated with adherence to the study-defined PA goal in a mobile health (mHealth) weight loss trial. METHODS: A secondary analysis was conducted of a 12-month weight loss trial (SMARTER) that randomized 502 adults with overweight or obesity to either self-monitoring of diet, PA, and weight with tailored feedback messages ( n = 251) or self-monitoring alone ( n = 251). The primary outcome was average adherence to the PA goal of ≥150 min·wk -1 of moderate- and vigorous-intensity aerobic activities (MVPA) from Fitbit Charge 2™ trackers over 52 wk. Twenty-five explanatory variables were considered. Machine learning methods and linear regression were used to identify predictors of adherence to the PA goal. RESULTS: The sample ( N = 502) was mostly female (80%), White (82%) with the average age of 45 ± 14.4 yr and body mass index of 33.7 ± 4.0 kg·m -2 . Machine learning methods identified PA goal adherence for the first week as the most important predictor of long-term PA goal adherence. In the parsimonious linear regression model, higher PA goal adherence for the first week, greater PA FB messages opened, older age, being male, higher education, being single and not having obstructive sleep apnea were associated with higher long-term PA goal adherence. CONCLUSIONS: To our knowledge, this is the first study using machine learning approaches to identify predictors of long-term PA goal adherence in a mHealth weight loss trial. Future studies focusing on facilitators or barriers to PA among young and middle-age adults and women with low PA goal adherence are warranted.

RESUMO

Background Utility of high-density lipoprotein cholesterol (HDL-C) in assessing the antiatherogenic properties of HDL may be limited in midlife women. Novel metrics of HDL function, lipid contents, and subclasses may better reflect the atheroprotective capacities of HDL, supporting the need to evaluate how cardiovascular health affects these metrics in women. We assessed the relationship of early midlife Life's Simple 7 (LS7) score and its health behavior components with future HDL function (HDL-cholesterol efflux capacity), HDL-phospholipid, HDL-triglyceride, HDL particles (HDL-P) and size, and the relationship between LS7 score and changes in HDL metrics over time. Methods and Results We analyzed 529 women (baseline age: 46.4 [2.6] years, 57% White) from the SWAN HDL (Study of Women's Health Across the Nation HDL) study who had baseline LS7 followed by future repeated HDL metrics. Multivariable linear mixed models were used. Higher LS7 score was associated with favorable future HDL profile (higher HDL-phospholipid, total HDL-P and large HDL-P, lower HDL-triglyceride, and larger overall HDL size). Ideal body mass index was associated with higher HDL-cholesterol efflux capacity, HDL-phospholipid, and large HDL-P, lower HDL-triglyceride and small HDL-P, and larger overall HDL size. Ideal physical activity was associated with higher HDL-phospholipid, and total, large, and medium HDL-P. Ideal smoking was associated with less HDL-triglycerides. Diet was not related to HDL metrics. Higher LS7 score and ideal body mass index were associated with slower progression of HDL size over time. Conclusions Novel HDL metrics may better reflect the clinical utility of HDL. Improving lifestyle at midlife, particularly maintaining ideal body mass index, is associated with better future HDL phenotype.

RESUMO

BACKGROUND: Whether changes in blood pressure (BP) over women's midlife are more driven by chronological aging or the menopause transition has been debated. We sought to determine whether women can be classified into distinct trajectory groups based on pattern and level of systolic BP (SBP), diastolic BP, pulse pressure (PP), and mean arterial pressure (MAP) over the menopause transition, and to assess whether menopause-related factors predict the group and level of BP measures. METHODS: Participants were from the SWAN (Study of Women's Health Across the Nation). Group-based trajectory modeling was used to identify women who shared distinct BP trajectories over time relative to menopause onset and to assess associations of menopause-related factors with trajectory group and level of BP measures. An accelerated rise relative to menopause onset suggests a menopause contribution. RESULTS: The study included 3302 multiracial and multiethnic women with BP measures over 17 follow-up visits (baseline age [SD]: 46.3 [2.7]). Women were classified into either low, medium, or high trajectory group in each BP measure. The low SBP, PP, and MAP trajectories (in 35%, 53%, and 28% of the cohort, respectively) were rising slowly before menopause but showed a significant accelerated rise 1 year after menopause, indicating a menopause contribution. The remaining BP trajectories were rising up until menopause and either continued with the same rise or declined after menopause. A younger menopause age predicted the low SBP, PP, and MAP trajectories. A greater follicle-stimulating hormone level predicted lower SBP and PP levels, while vasomotor symptoms occurrence predicted higher SBP, PP, and MAP levels over time. Estradiol did not predict trajectory or level of any BP measure. CONCLUSIONS: Distinct BP trajectories over the menopause transition exist that revealed a group of women whose SBP, PP, and MAP trajectories are consistent with a menopause contribution. Our findings support frequent monitoring of BP during the menopause transition.

RESUMO

Background Educational attainment is protective for cardiovascular health (CVH), but the benefits of education may not persist across racial and ethnic groups. Our objective was to determine whether the association between educational attainment and ideal CVH differs by race and ethnicity in a nationally representative sample. Methods and Results Using the National Health and Nutrition Examination Survey, we determined the distribution of ideal CVH, measured by Life's Simple 7, across levels of educational attainment. We used multivariable ordinal logistic regression to assess the association between educational attainment (less than high school, high school graduate, some college, college graduate) and Life's Simple 7 category (ideal, intermediate, poor), by race and ethnicity (Asian, Black, Hispanic, White). Covariates were age, sex, history of cardiovascular disease, health insurance, access to health care, and income-poverty ratio. Of 7771 National Health and Nutrition Examination Survey participants with complete data, as level of educational attainment increased, the criteria for ideal health were more often met for most metrics. After adjustment for covariates, effect of education was attenuated but remained significant (P<0.01). Those with at least a college degree had 4.12 times the odds of having an ideal Life's Simple 7 compared with less than high school (95% CI, 2.70-5.08). Among all racial and ethnic groups, as level of educational attainment increased, so did Life's Simple 7. The magnitude of the association between education and CVH varied by race and ethnicity (interaction P<0.01). Conclusions Our findings demonstrate that educational attainment has distinct associations with ideal CVH that differs by race and ethnicity. This work demonstrates the need to elucidate barriers preventing individuals from racial and ethnic minority groups from achieving equitable CVH.

RESUMO

CONTEXT: Novel metrics of high-density lipoprotein (HDL) (subclasses, lipid content, and function) may improve characterization of the anti-atherogenic features of HDL. In midlife women, changes in these metrics vary by time relative to the final menstrual period (FMP), supporting a contribution of estradiol (E2) and follicle-stimulating hormone (FSH). OBJECTIVE: We tested associations of endogenous E2 and FSH with novel HDL metrics and assessed whether these associations varied by time relative to FMP. METHODS: This study was a longitudinal analysis from the Study of Women's Health Across the Nation (SWAN) HDL study, using a community-based cohort of 463 women, baseline mean age 50.2 (2.7) years. The main outcome measures were HDL cholesterol efflux capacity (HDL-CEC), HDL phospholipids (HDL-PL), HDL triglycerides (HDL-Tg), HDL particles (HDL-P), HDL size, and HDL cholesterol (HDL-C). RESULTS: In multivariable analyses, E2 was positively associated with HDL size, large HDL-P, HDL-CEC, and HDL-Tg, but negatively with medium HDL-P (P values < 0.05). The positive association between E2 and HDL-Tg was stronger 2 years post-FMP than before, (interaction P = 0.031). FSH was positively related to total and medium HDL-P, but negatively to HDL size, large HDL-P, and HDL-CEC per particle (P values < 0.05). Associations of higher FSH with greater total HDL-P and smaller HDL size were only evident at/after menopause (interaction P values < 0.05). CONCLUSION: Some of the associations linking E2 and FSH with novel HDL metrics were vulnerable to time relative to menopause onset. Whether a late initiation of hormone therapy relative to menopause could have a detrimental effect on lipid content of HDL particles should be tested in the future.

RESUMO

Importance: Alteration in lung microbes is associated with disease progression in idiopathic pulmonary fibrosis. Objective: To assess the effect of antimicrobial therapy on clinical outcomes. Design, Setting, and Participants: Pragmatic, randomized, unblinded clinical trial conducted across 35 US sites. A total of 513 patients older than 40 years were randomized from August 2017 to June 2019 (final follow-up was January 2020). Interventions: Patients were randomized in a 1:1 allocation ratio to receive antimicrobials (n = 254) or usual care alone (n = 259). Antimicrobials included co-trimoxazole (trimethoprim 160 mg/sulfamethoxazole 800 mg twice daily plus folic acid 5 mg daily, n = 128) or doxycycline (100 mg once daily if body weight <50 kg or 100 mg twice daily if ≥50 kg, n = 126). No placebo was administered in the usual care alone group. Main Outcomes and Measures: The primary end point was time to first nonelective respiratory hospitalization or all-cause mortality. Results: Among the 513 patients who were randomized (mean age, 71 years; 23.6% women), all (100%) were included in the analysis. The study was terminated for futility on December 18, 2019. After a mean follow-up time of 13.1 months (median, 12.7 months), a total of 108 primary end point events occurred: 52 events (20.4 events per 100 patient-years [95% CI, 14.8-25.9]) in the usual care plus antimicrobial therapy group and 56 events (18.4 events per 100 patient-years [95% CI, 13.2-23.6]) in the usual care group, with no significant difference between groups (adjusted HR, 1.04 [95% CI, 0.71-1.53; P = .83]. There was no statistically significant interaction between the effect of the prespecified antimicrobial agent (co-trimoxazole vs doxycycline) on the primary end point (adjusted HR, 1.15 [95% CI 0.68-1.95] in the co-trimoxazole group vs 0.82 [95% CI, 0.46-1.47] in the doxycycline group; P = .66). Serious adverse events occurring at 5% or greater among those treated with usual care plus antimicrobials vs usual care alone included respiratory events (16.5% vs 10.0%) and infections (2.8% vs 6.6%); adverse events of special interest included diarrhea (10.2% vs 3.1%) and rash (6.7% vs 0%). Conclusions and Relevance: Among adults with idiopathic pulmonary fibrosis, the addition of co-trimoxazole or doxycycline to usual care, compared with usual care alone, did not significantly improve time to nonelective respiratory hospitalization or death. These findings do not support treatment with these antibiotics for the underlying disease. Trial Registration: ClinicalTrials.gov Identifier: NCT02759120.

RESUMO

Background Most women occupy multiple social roles during midlife. Perceived stress and rewards from these roles may influence health behaviors and risk factors. This study examined whether social role stress and reward were associated with the American Heart Association Life's Simple 7 in a cohort of midlife women in the United States. Methods and Results Women (n=2764) rated how stressful and rewarding they perceived their social roles during cohort follow-up (age range, 42-61 years). Body mass index, blood pressure, glucose, cholesterol, physical activity, diet, and smoking were assessed multiple times. All components were collected at the fifth study visit for 1694 women (mean age, 51 years). Adjusted linear and logistic regression models were used in analyses of the number of ideal components and the odds of achieving the ideal level of each component, respectively. Longitudinal analyses using all available data from follow-up visits were conducted. At the fifth visit, more stressful and less rewarding social roles were associated with fewer ideal cardiovascular factors. Higher average stress was associated with lower odds of any component of a healthy diet and an ideal blood pressure. Higher rewards were associated with greater odds of ideal physical activity and nonsmoking. Longitudinal analyses produced consistent results; moreover, there was a significant relationship between greater stress and lower odds of ideal glucose and body mass index. Conclusions Perceived stress and rewards from social roles may influence cardiovascular risk factors in midlife women. Considering social role qualities may be important for improving health behaviors and risk factors in midlife women.

RESUMO

BACKGROUND: Elevated low-density lipoprotein cholesterol (LDL-C) is associated with increased cardiovascular events, especially in high-risk populations. OBJECTIVES: This study sought to evaluate the influence of LDL-C on the incidence of cardiovascular events either following a coronary revascularization procedure (percutaneous coronary intervention [PCI] or coronary artery bypass grafting [CABG]) or optimal medical therapy alone in patients with established coronary heart disease and type 2 diabetes (T2DM). METHODS: Patient-level pooled analysis of 3 randomized clinical trials was undertaken. Patients with T2DM were categorized according to the levels of LDL-C at 1 year following randomization. The primary endpoint was major adverse cardiac or cerebrovascular events ([MACCE] the composite of all-cause mortality, nonfatal myocardial infarction, and nonfatal stroke). RESULTS: A total of 4,050 patients were followed for a median of 3.9 years after the index 1-year assessment. Patients whose 1-year LDL-C remained ≥100 mg/dl experienced higher 4-year cumulative risk of MACCE (17.2% vs. 13.3% vs. 13.1% for LDL-C between 70 and <100 mg/dl and LDL-C <70 mg/dl, respectively; p = 0.016). When compared with optimal medical therapy alone, patients with PCI experienced a MACCE reduction only if 1-year LDL-C was <70 mg/dl (hazard ratio: 0.61; 95% confidence interval: 0.40 to 0.91; p = 0.016), whereas CABG was associated with improved outcomes across all 1-year LDL-C strata. In patients with 1-year LDL-C ≥70 mg/dl, patients undergoing CABG had significantly lower MACCE rates as compared with PCI. CONCLUSIONS: In patients with coronary heart disease with T2DM, lower LDL-C at 1 year is associated with improved long-term MACCE outcome in those eligible for either PCI or CABG. When compared with optimal medical therapy alone, PCI was associated with MACCE reductions only in those who achieved an LDL-C <70 mg/dl.

RESUMO

OBJECTIVE: To identify groups of women who share levels and patterns of change in follicle-stimulating hormone (FSH), self-reported sleep maintenance problems, and frequent vasomotor symptoms (VMS) up to 10 years before and after their final menstrual period and to evaluate their premenopausal characteristics. METHOD: Group-based multi-trajectory modeling grouped 1,407 women from the Study of Women's Health Across the Nation who had an observed natural menopause and did not use hormone therapy, based on repeated measures of FSH, sleep maintenance problems, and frequent VMS relative to final menstrual period. Multivariable analyses assessed race/ethnicity, body mass index, smoking, and depressive symptoms as predictors of group membership. RESULTS: Women formed five distinct groups: (1) low symptoms (low VMS/sleep problems)/high FSH rise (N = 552; 39.2%); (2) moderate VMS and sleep problems/low FSH rise (N = 169; 12.0%); (3) dominant sleep problems (lower VMS/high sleep problems)/high FSH rise (N = 203; 14.4%); (4) dominant VMS (high VMS/lower sleep problems)/high FSH rise (N = 297; 21.1%)); and (5) high symptoms (high VMS/high sleep problems)/intermediate FSH rise (N = 186; 13.2%)). Multivariate analyses showed that race/ethnicity, premenopausal body mass index and depressive symptoms, and increasing depressive symptoms during the early phase of the transition predicted group membership. CONCLUSIONS: Women can be classified based on shared levels and patterns of FSH, sleep maintenance problems, and frequent VMS across the menopause transition. Either VMS or sleep maintenance problems can be dominant in the face of high FSH. Experiencing one menopause-related symptom or hormone profile does not automatically imply that another is also being experienced.

RESUMO

Background: Severe maternal morbidity is an important proxy for maternal mortality. Population attributable fraction is the proportion of a disease that is attributable to a given risk factor and can be used to estimate the reduction in the disease that would be anticipated if a risk factor was reduced or eliminated. Objective: We sought to determine the population-attributable fraction (PAF) of potentially modifiable risk factors for severe maternal morbidity. Study Design: We used a retrospective cohort of 86,260 delivery hospitalizations from Magee-Womens Hospital, Pittsburgh, PA for this analysis (2003-2012). Severe maternal morbidity was defined as any of the following: Centers for Disease Control and Prevention International Classification of Diseases 9th Revision diagnosis and procedure codes for the identification of maternal morbidity; prolonged postpartum length of stay (defined as >3 standard deviations beyond the mean length of stay: >3 days for vaginal deliveries and >5 days for Cesarean deliveries); or maternal intensive care unit admission. We used multivariable logistic regression with generalized estimating equations to estimate the association of prepregnancy overweight or obesity, maternal age ≥35 years, preexisting hypertension, preexisting diabetes, excessive gestational weight gain, smoking, education, and marital status with severe maternal morbidity. We then calculated the PAF for each risk factor. We also examined the impact of modest reductions and elimination of risk factors on the PAF of severe maternal morbidity. Results: The overall rate of severe maternal morbidity was 2.0%. Overweight and obesity, maternal age ≥35 years, preexisting hypertension, excessive gestational weight gain, and lack of a college degree had PAF ranging from 4.5% to 13%. If all risk factors were eliminated, 36% of cases could have been prevented. Modest reductions in the prevalence of excessive BMI and advanced maternal age had minimal impact on preventing severe maternal morbidity. Smoking during pregnancy and marital status were not associated with severe maternal morbidity. Conclusions: Our data suggest maternal morbidity can be reduced by modifying common, individual-level risk factors. Nevertheless, the majority of cases were not attributable to the patient level risk factors we examined. These data support the need for large studies of patient-, provider-, system- and population-level factors to identify high-impact interventions to reduce maternal morbidity.

RESUMO

BACKGROUND: A greater frequency of vasomotor symptoms (VMSs) has been associated with higher low-density lipoprotein cholesterol (LDL-C), but the association with high-density lipoprotein cholesterol (HDL-C) remains unclear. Endogenous estradiol (E2) levels are associated with both VMS and lipid levels and thus may confound such associations. OBJECTIVES: To assess the relationship of VMS frequency with HDL-C, LDL-C, and lipoprotein concentrations (HDL and LDL particles [HDL-P; LDL-P]) and lipoprotein sizes in midlife women and to evaluate whether these associations are explained by E2. METHODS: Participants were from the Study of Women's Health Across the Nation (SWAN) HDL ancillary study who had both nuclear magnetic resonance (NMR) spectroscopy lipoprotein subclass metrics and self-reported frequency of VMS measured 2-5 times over the menopause transition. VMS frequency was categorized into none, 1-5 days (infrequent), or ≥6 days (frequent) within the past 2 weeks. RESULTS: We evaluated 522 women [at baseline: mean age 50.3 (SD: 2.8) years; infrequent VMS: 29.8%, frequent VMS: 16.5%]. Adjusting for potential confounders except E2, frequent VMS was associated with smaller HDL size [ß(SE): -0.06 (0.03); P = .04] and higher concentrations of LDL-C [ß(SE): 3.58 (1.77); P = .04] and intermediate LDL-P [ß(SE): 0.09 (0.05); P = .04] than no VMS. These associations were largely explained by E2, all P's > .05. CONCLUSIONS: Frequent VMSs were associated with smaller HDL size and higher concentrations of LDL-C and intermediate LDL-P. These associations were explained by endogenous E2. Whether treating frequent VMS with exogenous E2 could simultaneously improve lipids/lipoproteins profile should be assessed in future studies.

RESUMO

Severe traumatic brain injury (TBI) activates a robust systemic response that involves inflammatory and other factors, including estradiol (E2), associated with increased deaths. Tumor necrosis factor-alpha (TNFα) is a significant mediator of systemic shock, and it is an extra-gonadal transcription factor for E2 production. The study objectives were to test the hypotheses: (1) a positive feedback relationship exists between acute serum TNFα and E2; and (2) acute concentrations of E2 and TNFα are prognostic indicators of death after severe TBI. This prospective cohort study included N = 157 adults with severe TBI. Serum samples were collected for the first five days post-injury. The TNFα and E2 levels were averaged into two time epochs: first 72 h (T1) and second 72 h post-injury (T2). A cross-lag panel analysis conducted between T1 and T2 TNFα and E2 levels showed significant cross-lag effects: T1 TNFα and T1 E2 were related to T2 E2 and T2 TNFα, respectively. Cox proportional hazards multi variable regression models determined that increases in T1 E2 (hazard ratio [HR] = 1.79, 95% confidence interval [CI]: 1.15, 2.81), but not T2 E2 (HR = 0.91, 95% CI: 0.56, 1.47), were associated with increased risk of death. Increased T2 TNFα (HR = 2.47, 95% CI: 1.35, 4.53), and T1 TNFα (HR = 1.47, 95% CI: 0.99, 2.19), to a lesser degree, were associated with increased risk of death. Relationships of death with T2 TNFα and T1 E2 were mediated partially by cardiovascular, hepatic, and renal dysfunction. Both E2 and TNFα are systemic, reciprocally related biomarkers that may be indicative of systemic compromise and increased risk of death after severe TBI.

RESUMO

OBJECTIVE: To identify the association of newly developed prepregnancy overweight and obesity with stillbirth and infant mortality. METHODS: We studied subsequent pregnancies of mothers who were normal weight at fertilization of their first identified pregnancy, from a population-based cohort that linked birth registry with death records in Pennsylvania, 2003-2013. Women with newly developed prepregnancy overweight and obesity were defined as those whose body mass index (BMI) before second pregnancy was between 25 and 29.9 or 30 or higher, respectively. Our main outcomes of interest were stillbirth (intrauterine death at 20 weeks of gestation or greater), infant mortality (less than 365 days after birth), neonatal death (less than 28 days after birth) and postneonatal death (29-365 days after birth). Associations of both prepregnancy BMI categories and continuous BMI with each outcome were estimated by nonparametric targeted minimum loss-based estimation and inverse-probability weighted dose-response curves, respectively, adjusting for race-ethnicity, smoking, and other confounders (eg, age, education). RESULTS: A cohort of 212,889 women were included for infant mortality analysis (192,941 women for stillbirth analysis). The crude rate of stillbirth and infant mortality in these final analytic cohorts were 3.3 per 1,000 pregnancies and 2.9 per 1,000 live births, respectively. Compared with women who stayed at a normal weight in their second pregnancies, those becoming overweight had 1.4 (95% CI 0.6-2.1) excess stillbirths per 1,000 pregnancies. Those becoming obese had 3.6 (95% CI 1.3-5.9) excess stillbirths per 1,000 pregnancies and 2.4 (95% CI 0.4-4.4) excess neonatal deaths per 1,000 live births. There was a dose-response relationship between prepregnancy BMI increases of more than 2 units and increased risk of stillbirth and infant mortality. In addition, BMI increases were associated with higher risks of infant mortality among women with shorter interpregnancy intervals (less than 18 months) compared with longer intervals. CONCLUSION: Transitioning from normal weight to overweight or obese between pregnancies was associated with an increased risk of stillbirth and neonatal mortality.

RESUMO

OBJECTIVE: Heart fat deposition has been linked to atherosclerosis, and both accelerate after menopause. Hormone therapy (HT) may differentially slow heart fat deposition and progression of atherosclerosis, depending on the specific HT agent or its route of administration. Our objective was to evaluate the effects of different HT agents, oral and transdermal, on associations between heart fat accumulation and atherosclerosis progression, measured by carotid intima-media thickness (CIMT), in recently menopausal women from the Kronos Early Estrogen Prevention Study (KEEPS) trial. METHODS: KEEPS was a randomized, placebo-controlled trial of the effects of 0.45 mg/d oral conjugated equine estrogens (o-CEE) or 50 mcg/d transdermal 17ß-estradiol (t-E2), compared with placebo, on 48 months progression of CIMT. Epicardial adipose tissue (EAT) and paracardial adipose tissue (PAT) volumes were quantified by computed tomography. RESULTS: In all, 467 women (mean age [SD] 52.7 [2.5]; 78.2% White; 30% on o-CEE, 30.8% t-E2, 39.2% placebo) with heart fat volumes and CIMT at baseline and 48 months were included. EAT and PAT changes were not associated with CIMT progression; however, the assigned treatment significantly modified the association between PAT (but not EAT) change and CIMT progression. In the o-CEE group, adjusted CIMT progression was 12.66 µm (95% confidence interval [CI] 1.80, 23.52) lower than in t-E2 group (P = 0.02), and 10.09 µm (95% CI 0.79, 19.39) lower than in placebo group (P = 0.03), as per 1-SD increase in PAT. CONCLUSION: Compared with t-E2, o-CEE appears to slow down the adverse effect of increasing PAT on progression of atherosclerosis. Whether this beneficial association is specific to CEE or to the oral route of CEE administration is unclear and should be assessed further.

RESUMO

BACKGROUND: Individuals with traumatic brain injury (TBI) have extended inpatient hospital stays that include prolonged mechanical ventilation, increasing risk for infections, including pneumonia. Studies show the negative short-term effects of hospital-acquired pneumonia (HAP) on hospital-based outcomes; however, little is known of its long-term effects. METHODS: A prospective cohort study was conducted. National Trauma Databank and Traumatic Brain Injury Model Systems were merged to derive a cohort of 3,717 adults with moderate-to-severe TBI. Exposure data were gathered from the National Trauma Databank, and outcomes were gathered from the Traumatic Brain Injury Model Systems. The primary outcome was the Glasgow Outcome Scale-Extended (GOS-E), which was collected at 1, 2, and 5 years postinjury. The GOS-E was categorized as favorable (>5) or unfavorable (≤5) outcomes. A generalized estimating equation model was fitted estimating the effects of HAP on GOS-E over the first 5 years post-TBI, adjusting for age, race, ventilation status, brain injury severity, injury severity score, thoracic Abbreviated Injury Scale score of 3 or greater, mechanism of injury, intraventricular hemorrhage, and subarachnoid hemorrhage. RESULTS: Individuals with HAP had a 34% (odds ratio, 1.34; 95% confidence interval, 1.15-1.56) increased odds for unfavorable GOS-E over the first 5 years post-TBI compared with individuals without HAP, after adjustment for covariates. There was a significant interaction between HAP and follow-up, such that the effect of HAP on GOS-E declined over time. Sensitivity analyses that weighted for nonresponse bias and adjusted for differences across trauma facilities did not appreciably change the results. Individuals with HAP spent 10.1 days longer in acute care and 4.8 days longer in inpatient rehabilitation and had less efficient functional improvement during inpatient rehabilitation. CONCLUSION: Individuals with HAP during acute hospitalization have worse long-term prognosis and greater hospital resource utilization. Preventing HAP may be cost-effective and improve long-term recovery for individuals with TBI. Future studies should compare the effectiveness of different prophylaxis methods to prevent HAP. LEVEL OF EVIDENCE: Prospective cohort study, level III.

RESUMO

Background Heart fats (epicardial and paracardial adipose tissue [PAT]) are greater after menopause. Endogenous estrogen may regulate these fat depots. We evaluated the differential effects of hormone therapy formulations on heart fat accumulations and their associations with coronary artery calcification (CAC) progression in recently menopausal women from KEEPS (Kronos Early Estrogen Prevention Study). Methods and Results KEEPS was a multicenter, randomized, placebo-controlled trial of the effects of 0.45 mg/d oral conjugated equine estrogens and 50 µg/d transdermal 17ß-estradiol, compared with placebo, on 48-month progression of subclinical atherosclerosis among 727 early menopausal women. CAC progression was defined if baseline CAC score was 0 and 48-month CAC score was >0 or if baseline CAC score was >0 and <100 and annualized change in CAC score was ≥10. Of 727 KEEPS participants, 474 (mean age: 52.7 [SD: 2.6]; 78.1% white) had computed tomography-based heart fat and CAC measures at both baseline and 48 months. Compared with women on placebo, women on oral conjugated equine estrogens were less likely to have any increase in epicardial adipose tissue (odds ratio for oral conjugated equine estrogens versus placebo: 0.62 [95% CI, 0.40-0.97]; P=0.03). PAT did not change in any group. Changes in epicardial adipose tissue and PAT did not differ by treatment group. CAC increased in 14% of participants. The assigned treatment modified the association between PAT changes and CAC progression (P=0.02) such that PAT increases were associated with CAC increases only in the transdermal 17ß-estradiol group. Conclusions In recently menopausal women, oral conjugated equine estrogens may slow epicardial adipose tissue accumulation, whereas transdermal 17ß-estradiol may increase progression of CAC associated with PAT accumulation.

RESUMO

BACKGROUND: The optimal coronary revascularization strategy in patients with stable ischemic heart disease (SIHD) who have type 2 diabetes (T2DM) and chronic kidney disease (CKD) remains unclear. OBJECTIVES: This patient-level pooled analysis sought to compare outcomes of 3 large, federally-funded randomized trials in SIHD patients with T2DM and CKD (COURAGE [Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation], BARI 2D [Bypass Angioplasty Revascularization Investigation 2 Diabetes], and FREEDOM [Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multi-vessel Disease]). METHODS: The primary endpoint was the composite of major adverse cardiovascular or cerebrovascular events (MACCE) including all-cause death, myocardial infarction (MI), or stroke adjusted for trial and randomization strategy. RESULTS: Of the 4,953 patients with available estimated glomerular filtration rate (eGFR) at baseline, 1,058 had CKD (21.4%). CKD patients were more likely to be older, be female, and have a history of heart failure. CKD subjects were more likely to experience a MACCE (adjusted hazard ratio [HR]: 1.48; 95% confidence interval [CI]: 1.28 to 1.71; p = 0.0001) during a median 4.5-year follow-up. Both mild (eGFR 45 to 60 ml/min/1.73 m2) and moderate to severe (eGFR <45 ml/min/1.73 m2) CKD predicted MACCE (adjusted HRs: 1.25 and 2.26, respectively). For patients without CKD, coronary artery bypass graft (CABG) surgery combined with optimal medical therapy (OMT) was associated with lower MACCE rates compared with percutaneous coronary intervention (PCI) + OMT (adjusted HR: 0.69; 95% CI: 0.55 to 0.86; p = 0.001). For the comparison of CABG + OMT versus PCI + OMT in the CKD group, there was only a statistically significant difference in subsequent revascularization rates (HR: 0.25; 95% CI: 0.15 to 0.41; p = 0.0001) but not in MACCE rates. CONCLUSIONS: Among SIHD patients with T2DM and no CKD, CABG + OMT significantly reduced MACCE compared with PCI + OMT. In subjects with CKD, there was a nonsignificant trend toward a better MACCE outcome with CABG and a significant reduction in subsequent revascularization.

RESUMO

BACKGROUND AND AIMS: The impact of treatment strategies on outcomes in patients with stable coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM) according to presenting angina has not been rigorously assessed. METHODS: We performed a patient-level pooled-analysis (n = 5027) of patients with stable CAD and T2DM randomized to optimal medical therapy [OMT], percutaneous coronary intervention [PCI] + OMT, or coronary artery bypass grafting [CABG] + OMT. Endpoints were death/myocardial infarction (MI)/stroke, post-randomization revascularization (both over 5 years), and angina control at 1 year. RESULTS: Increasing severity of baseline angina was associated with higher rates of death/MI/stroke (p = 0.009) and increased need for post-randomization revascularization (p = 0.001); after multivariable adjustment, only association with post-randomization revascularization remained significant. Baseline angina severity did not influence the superiority of CABG + OMT to reduce the rate of death/MI/stroke and post-randomization revascularization compared to other strategies. CABG + OMT was superior for angina control at 1 year compared to both PCI + OMT and OMT alone but only in patients with ≥ Class II severity at baseline. Comparisons between PCI + OMT and OMT were neutral except that PCI + OMT was superior to OMT for reducing the rate of post-randomization revascularization irrespective of presenting angina severity. CONCLUSIONS: Presenting angina severity did not influence the superiority of CABG + OMT with respect to 5-year rates of death/MI/stroke and need for post-randomization revascularization. Presenting angina severity minimally influenced relative benefits for angina control at 1 year.
