Exploring the impact of arginine-supplemented immunonutrition on length of stay in the intensive care unit: A retrospective cross-sectional analysis.

BACKGROUND: Arginine-supplemented enteral immunonutrition has been designed to optimize outcomes in critical care patients. Existing formulas may be isocaloric and isoproteic, yet differ in L-arginine content, energy distribution, and in source and amount of many other specialized ingredients. The individual contributions of each may be difficult to pinpoint; however, all cumulate in the body's response to illness and injury. The study objective was to compare health outcomes between different immunonutrition formulas. METHODS: Real-world data from October 2015 -February 2019 in the PINC AI™ Healthcare Database (formerly the Premier Healthcare Database) was reviewed for patients with an intensive care unit (ICU) stay and ≥3 days exclusive use of either higher L-arginine formula (HAF), or lower L-arginine formula (LAF). Multivariable generalized linear model regression was used to check associations between formulas and ICU length of stay. RESULTS: 3,284 patients (74.5% surgical) were included from 21 hospitals, with 2,525 receiving HAF and 759 LAF. Inpatient mortality (19.4%) and surgical site infections (6.2%) were similar across groups. Median hospital stay of 17 days (IQR: 16) did not differ by immunonutrition formula. Median ICU stay was shorter for patients receiving HAF compared to LAF (10 vs 12 days; P<0.001). After adjusting for demographics, visit, severity of illness, and other clinical characteristics, associated regression-adjusted ICU length of stay for patients in the HAF group was 11% shorter [0.89 (95% CI: 0.84, 0.94; P<0.001)] compared to patients in the LAF group. Estimated adjusted mean ICU length of stay was 9.4 days (95% CI: 8.9, 10.0 days) for the HAF group compared to 10.6 days (95% CI: 9.9, 11.3 days) for the LAF group (P<0.001). CONCLUSIONS: Despite formulas being isocaloric and isoproteic, HAF use was associated with significantly reduced ICU length of stay, compared to LAF. Higher arginine immunonutrition formula may play a role in improving health outcomes in primarily surgical critically ill patients.

Characteristics and feeding intolerance in critically ill adult patients receiving peptide-based enteral nutrition: A retrospective cross-sectional study.

BACKGROUND & AIMS: Patients who experience gastrointestinal (GI) intolerance and hyperglycemia (or glucose intolerance) may not achieve appropriate caloric requirements and experience poor outcomes. The aim was to examine patient characteristics, disease severity, and enteral nutrition (EN) formula use in relation to feeding intolerance and healthcare resource utilization. METHODS: A retrospective, cross-sectional design using real-world data from PINC AI™ Healthcare Database, 2015-2019 was used. Critically ill hospitalized adults who required ≥3 days of 100% whey peptide-based EN, other peptide-based diets, or intact-protein standard and diabetic EN formulas were included. Primary outcomes were enteral feeding intolerance, including GI intolerance and hyperglycemia. Pairwise comparisons of other peptide-based and standard intact-protein groups with 100% whey-peptide were completed. Associations between EN group with GI intolerance and hyperglycemia, respectively, were evaluated via multivariable logistic regressions. RESULTS: Across 67 US hospitals, 19,679 inpatients (3242,100% whey-peptide, 3121 other peptide-based, and 13,316 standard intact-protein) were included. The 100% whey-peptide group had higher severity of illness and frequencies of comorbidities compared with other peptide-based and standard intact-protein groups. Hospital length of stay, intensive care unit stay, and 30-day readmission were similar across peptide-based cohorts. After controlling for demographic, visit, and severity characteristics, odds of GI intolerance were 18% higher for the other peptide-based group and 15% higher for the standard intact-protein group compared with the 100% whey-peptide group (each P < 0.03). In secondary analysis, odds of hyperglycemia were 81% higher for the other peptide-based group compared with the subgroup of very high-protein/low carbohydrate 100% whey-peptide (P < 0.001). CONCLUSIONS: Lower GI intolerance and greater glycemic control were associated with the use of 100% whey-peptide formulas relative to other formulas. Appropriate and optimal delivery of EN using specialized peptide-based formulas is a strategy to minimize feeding intolerance and benefit critically ill patients.

Characteristics, Hospital Length of Stay, and Readmissions Among Individuals Undergoing Abdominal Ostomy Surgery: Review of a Large US Healthcare Database.

PURPOSE: The purpose of this study was to examine patient characteristics, length of stay (LOS), hospital revisits, and complications of patients undergoing abdominal ostomy surgery. DESIGN: Retrospective cohort study. SUBJECTS AND SETTING: Data were extracted from the PINC AI Healthcare Database (PHD), a large archive that stores data from 25% of all US inpatient hospital discharges. Patients were admitted to 658 hospitals in the United States between December 1, 2017, and November 30, 2018. The sample comprised 27,658 adult patients; 15,512 underwent creation of a colostomy, 10,207 underwent ileostomy construction, and 1930 had a urostomy procedure. Their median age was 64 years (interquartile range [IQR] = 19 years). Emergent admission type was 71.2% for patients who underwent a colostomy procedure, 49.4% for ileostomy, and 9.9% for urostomy. The majority of patients underwent open surgery (77.7%); 22.3% of procedures used an endoscopic approach. METHODS: Patients were identified as having undergone abdominal ostomy surgery via ICD-10-PCS (International Classification of Diseases, Tenth Revision, Procedure Coding System) procedure codes. Demographic, visit, hospital and clinical characteristics, LOS, and hospital revisits (ie, readmissions and emergency department [ED]) were captured for qualifying patients. Data were evaluated using unadjusted descriptive analyses. RESULTS: The median LOS of 9 days (IQR = 9 days) varied by ostomy surgery; the cumulative postsurgical LOS was 7 days (IQR = 5 days). The most frequent underlying diagnoses resulting in ostomy surgery were diverticulitis of the large bowel (19.6%) managed by colostomy, colorectal cancer managed by ileostomy (22.5%), or urothelial cancer managed by urostomy (78.1%). Slightly less than a quarter (23.7%) of patients were discharged home without home care, 43.0% went home with home healthcare, and 29.6% were discharged to a non-acute care facility. Hospital readmission within 120 days of discharge was 36.3% for patients with a colostomy, 52.3% for those with an ileostomy, and 34.6% for patients with a urostomy. Ostomy complications were identified as the reason for readmission in 62.4% of patients. Slightly more than 1 in 5 patients (20.7%) had a subsequent ED visit within 120 days, 39.7% of which involved ostomy complication. CONCLUSIONS: Characteristics of patients undergoing abdominal stoma surgery varied based on underlying diagnosis and ostomy type. The median hospital LOS was more than 1 week. Patients experienced high rates of healthcare utilization (hospital admission or ED visits) during the 120 days following surgery.

Assessment of Healthcare Resource Utilization by Anticoagulant Heparinoid Dosage Level in Patients Hospitalized with COVID-19.

The aim was to describe inpatients with COVID-19 empirically prescribed heparinoid anticoagulants and compare resource utilization between prophylactic/low-dose and therapeutic/high-dose groups. Methods: This retrospective observational study used real-world data from 880 US hospitals in the PINC AI™ Healthcare Database during 4/1/2020-11/30/2020. Descriptive analysis was used to characterize patients. Multivariable regression was used to evaluate intensive care unit (ICU) admissions, length of stay (LOS), mortality, and costs by anticoagulation dose group, adjusting for cohort characteristics. Among 122,508 inpatients, 29,225 (23.9%) received therapeutic/high-dose, and 93,283 (76.1%) received prophylactic/low-dose anticoagulation. The high-dose group had more comorbidities and worse laboratory values compared with low-dose. Respectively, ICU admission rates were 36.7% and 19.1% and LOS median (Q1, Q3) was 8 (5, 15) and 5 (3, 9) days. In separate adjusted models, high-dose anticoagulation was associated with a 45% increase in odds of ICU admission, 26% increase in odds of in-hospital mortality, 21% longer average LOS, and 28% greater average total cost compared with low-dose (each P < 0.001). Prophylactic/low-dose anticoagulation treatment was associated with decreased healthcare resource utilization (HRU) in hospitalized patients with COVID-19.

Healthcare Resource Utilization and Cost Comparisons of High-Protein Enteral Nutrition Formulas Used in Critically Ill Patients.

Background: High-protein enteral nutrition is advised for patients who are critically ill. Options include immunonutrition formulas of various compositions and standard high-protein formulas (StdHP). Additional research is needed on the health economic value of immunonutrition in a broad cohort of severely ill hospitalized patients. Objective: The study goal was to compare healthcare resource utilization (HCRU) and cost between immunonutrition and StdHP using real-world evidence from a large US administrative database. Methods: A retrospective cohort study was designed using the PINC AI™ Healthcare Database from 2015 to 2019. IMPACT® Peptide 1.5 (IP) was compared with Pivot® 1.5 (PC), and StdHP formulas. Inclusion criteria comprised patients age 18+ with at least 1 day's stay in the intensive care unit (ICU) and at least 3 out of 5 consecutive days of enteral nutrition. Pairwise comparisons of demographics, clinical characteristics, HCRU, and costs were conducted between groups. Multivariable regression was used to assess total hospital cost per day associated with enteral nutrition cohort. Results: A total of 5752 patients were identified across 27 hospitals. Overall, a median 7 days of enteral nutrition was received over a 16-day hospital and 10-day ICU stay. Median total and daily hospital costs were lower for IP vs PC ($71 196 vs $80 696, P<.001) and ($4208 vs $4373, P=.019), with each higher than StdHP. However, after controlling for covariates such as mortality risk, surgery, and discharge disposition, average total hospital cost per day associated with IP use was 24% lower than PC, and 12% lower than StdHP (P<.001). Readmissions within 30 days were less frequent for patients receiving IP compared with PC (P<.02) and StdHP (P<.001). Discussion: Choice of high-protein enteral nutrition for patients in the ICU has implications for HCRU and daily hospital costs. Considering these correlations is important when comparing formula ingredients and per unit costs. Among the enteral nutrition products studied, IP emerged as the most cost-saving option, with lower adjusted hospital cost per day than PC or StdHP. Conclusions: Using a select immunonutrition formula for critically ill patients may provide overall cost savings for the healthcare system.

Is Coronavirus Disease 2019 (COVID-19) Less Deadly Now? Trends in In-Hospital Mortality Among Hospitalized COVID-19 Patients in the United States.

After an initial decline from April through June 2020 (from 22.2% to 11.9%), adjusted in-hospital mortality in coronavirus disease 2019 (COVID-19) inpatients peaked twice and was significantly higher than June 2020 for subsequent months except in July and October 2020. Adjusted mortality trends differed across age groups between November 2020 and February 2021.

Evaluation of a Clinical Platform to Promote Chronic Disease Management.

Self-reported data suggest American adults with multiple chronic conditions account for 25.7% to 60% of the population. Despite emphasis on information technology to improve quality in health care, data addressing outcomes of clinically focused, provider-oriented dashboards are limited. To explore integrating performance platforms into clinical care, the authors designed a platform-based intervention to address 2 prevalent chronic conditions with significant long-term burden. This study used a performance platform to enhance clinicians' management of patients with diabetes and osteoporosis. Descriptive statistics were used to summarize patients' surveys and quality metrics, and to analyze clinicians' knowledge, attitudes, and beliefs in the pre and post time frames. The frequency of screening for osteoporosis in women improved post intervention (40% vs. 44%, P < 0.0001), whereas other quality metrics did not. Clinician respondents were primarily physicians (82%), white (73%), internal medicine specialists (58%), with an average of 18 years' experience, and nearly equally male and female. Their percent of correctly answered knowledge questions increased slightly in the postintervention phase for osteoporosis and hypoglycemia (0.53 and 1.74, respectively); however, results were not statistically significant (P > 0.4). Post intervention, clinicians reported that their attitudes and beliefs regarding disease management had changed in the past 6 months in a positive direction. Although few outcomes studied changed over time, results suggest that performance platforms may have a role to play in managing chronic conditions. However, their efficacy must continue to be evaluated in order to improve understanding of optimal approaches to integrating technology into patient care.

Psychosocial and health-related risk factors for depressive symptom trajectories among midlife women over 15 years: Study of Women's Health Across the Nation (SWAN).

BACKGROUND: Psychosocial and health-related risk factors for depressive symptoms are known. It is unclear if these are associated with depressive symptom patterns over time. We identified trajectories of depressive symptoms and their risk factors among midlife women followed over 15 years. METHODS: Participants were 3300 multiracial/ethnic women enrolled in a multisite longitudinal menopause and aging study, Study of Women's Health Across the Nation. Biological, psychosocial, and depressive symptom data were collected approximately annually. Group-based trajectory modeling identified women with similar longitudinal patterns of depressive symptoms. Trajectory groups were compared on time-invariant and varying characteristics using multivariable multinomial analyses and pairwise comparisons. RESULTS: Five symptom trajectories were compared (50% very low; 29% low; 5% increasing; 11% decreasing; 5% high). Relative to whites, blacks were less likely to be in the increasing trajectory and more likely to be in the decreasing symptom trajectory and Hispanics were more likely to have a high symptom trajectory than an increasing trajectory. Psychosocial/health factors varied between groups. A rise in sleep problems was associated with higher odds of having an increasing trajectory and a rise in social support was associated with lower odds. Women with low role functioning for 50% or more visits had three times the odds of being in the increasing symptom group. CONCLUSIONS: Changes in psychosocial and health characteristics were related to changing depressive symptom trajectories. Health care providers need to evaluate women's sleep quality, social support, life events, and role functioning repeatedly during midlife to monitor changes in these and depressive symptoms.

Childhood socioeconomic circumstances and depressive symptom burden across 15 years of follow-up during midlife: Study of Women's Health Across the Nation (SWAN).

Childhood socioeconomic disadvantage may contribute to adult depression. Understanding pathways by which early socioeconomic adversity may shape adult depression is important for identifying areas for intervention. Studies to date have focused on one potential pathway, adult socioeconomic status (SES), and assessed depression at only one or a few time points. Our aims were to examine (a) the association between childhood SES (low vs. high) and depressive symptom burden in midlife and (b) whether adult socioeconomic, psychosocial, and physical health characteristics are important pathways. Using annual data from a cohort of 1109 black and white US women recruited in 1996-1997, we evaluated the association between childhood SES and depressive symptom burden across 15 years in midlife and whether adult characteristics-financial difficulty, lower education, stressful events, low social support, low role functioning, medical conditions, and bodily pain-mediated the association. Depressive symptom burden was estimated by calculating area under the curve of annual scores across 15 years of the Center for Epidemiological Studies Depression (CES-D). In unadjusted models, low childhood SES was associated with greater depressive burden (P = 0.0002). Each hypothesized mediator, individually, did not reduce the association. However, when five of the hypothesized mediators were included together in the same analysis, they explained more than two thirds of the association between childhood SES and depressive symptom burden reducing the P value for childhood SES to non-significance (P = 0.20). These results suggest that childhood SES influences midlife depressive symptom burden through a cluster of economic stress, limited social resources, and physical symptoms in adulthood.

Patterns of depressive disorders across 13 years and their determinants among midlife women: SWAN mental health study.

BACKGROUND: Little is known about the course of depression in midlife women. This study aims to identify factors that distinguish risk factors for persistent or recurrent depression from those of a milder course across 13-years of follow-up. METHODS: 297 Black and White premenopausal women aged 42-52 were enrolled at the Study of Women's Health Across the Nation Pittsburgh site. Psychiatric interviews obtained information on lifetime psychiatric diagnoses at baseline and occurrences of depression annually. We identified four depression patterns: 91(31%) had Persistent/recurrent major depressive disorder (MDD), 27(9%) Single Episode MDD, 35(12%) Minor Depression (minD) only, 144(48%) No Depression. We compared baseline risk factors for the Persistent/recurrent MDD group with each of the other three. RESULTS: A lifetime history of major or minor depression (p-values =.001-.08) and 2+ very upsetting life events in the previous year (p-values=.003-.04) were more likely to be reported by women in the Persistent/recurrent group than in the other three. The Persistent/recurrent group was more likely to report a family history of depression (p=.03) than the MinD group, and to report current sleep problems (p=.002) at baseline than the Single Episode MDD group. LIMITATIONS: Small numbers of women with minD or a Single Episode MDD. Childhood maltreatment and family depression history were retrospectively reported. CONCLUSIONS: A Persistent/recurrent depression course is common during midlife. In addition to personal and family histories of depression, providers of midlife health care should recognize that current sleep problems and recent very upsetting events are strong risk factors for a pernicious depression course.

Persistence of depression in African American and Caucasian women at midlife: findings from the Study of Women Across the Nation (SWAN).

This study prospectively examined the course of depression in African American and Caucasian midlife women over an 11-year period. Racial differences in lifetime history of depression, severity of depressive symptoms and rates of depressive disorders at baseline, and persistence or recurrence of depression over an 11 year period were examined. Predictors of persistence/recurrence of depression were also examined. The sample was comprised of 423 midlife women enrolled in the Study of Women Across the Nation (SWAN) Mental Health Study (MHS). All participants completed baseline and annual assessments, which included self-reported measures of health, functioning, and psychosocial factors, and clinician administered assessments of psychiatric disorders. Logistic regression analyses were used to examine predictors of depression persistence/recurrence. Findings indicated that African American and Caucasian women did not differ significantly in rates of lifetime and baseline depressive disorders, or severity of depressive symptoms. Annual assessments revealed no significant differences between the groups in rates of persistent/recurrent depression. While African American and Caucasian women do not differ in recurrence of depression at midlife, factors associated with depression differed by race.

Psychosocial features associated with lifetime comorbidity of major depression and anxiety disorders among a community sample of mid-life women: the SWAN mental health study.

BACKGROUND: In clinical samples, comorbidity between depressive and anxiety disorders is associated with greater symptom severity and elevated suicide risk. Less is known, however, regarding the long-term psychosocial impact that a lifetime history of both major depressive disorder (MDD) and one or more anxiety disorders has in community samples. This report evaluates clinical, psychological, social, and stress-related characteristics associated with a lifetime history of MDD and anxiety. METHODS: Data from 915 women aged 42-52 who were recruited as part of the the Study of Women's Health across the Nation (SWAN) Mental Health Study were used to examine clinical and psychosocial features across groups of women with a lifetime history of MDD alone, anxiety alone, both MDD and anxiety, or neither MDD nor anxiety. RESULTS: As compared with women with a history of either MDD or anxiety alone, women with a comorbid history were more likely to report recurrent MDD, multiple and more severe lifetime anxiety disorders, greater depressive and anxiety symptoms, diminished social support, and more past-year distressing life events. Exploratory analyses indicated that women with a comorbid history also report more childhood abuse/neglect and diminished self-esteem, as compared with women with a history of either disorder alone. CONCLUSIONS: Midlife women with a comorbid history that includes both MDD and anxiety disorders report diminished social support, more symptomatic distress, and a more severe and recurrent psychiatric history. Future research is needed to clarify the biological and psychosocial risk factors associated with this comorobid profile, and to develop targeted interventions for this at-risk group.

Association of past and recent major depression and menstrual characteristics in midlife: Study of Women's Health Across the Nation.

OBJECTIVE: The aim of this study was to examine the association of a history of major depression (MD) with menstrual problems in a multiethnic sample of midlife women. METHODS: Participants were 934 women enrolled in the Study of Women's Health Across the Nation, a multisite study of menopause and aging. The outcomes were menstrual bleeding problems and premenstrual symptoms in the year before study entry. The Structured Clinical Interview for the Diagnosis of DSM-IV Axis I Disorders was conducted to determine recent and past psychiatric diagnoses. Covariates included sociodemographic, behavioral, and gynecologic factors. RESULTS: One third of the participants reported heavy bleeding, 20% reported other abnormal bleeding, and 18% reported premenstrual symptoms. One third had past and 11% had recent MD. Past MD was associated with an increased likelihood of heavy bleeding (odds ratio, 1.89; 95% CI, 1.25-2.85), adjusting for recent MD, menopause status, and other covariates. Past MD was not associated with other abnormal bleeding or premenstrual symptoms in the final analysis that adjusted for recent MD. CONCLUSIONS: Midlife women with a history of MD are more likely to report heavy bleeding.

Longitudinal change in reproductive hormones and depressive symptoms across the menopausal transition: results from the Study of Women's Health Across the Nation (SWAN).

CONTEXT: The contribution of reproductive hormones to mood has been the focus of considerable research. Results from clinical and epidemiological studies have been inconsistent. It remains unclear whether alterations in serum hormone levels across the menopausal transition are linked to depressive symptoms. OBJECTIVES: To evaluate the relationship between serum hormone levels and high depressive symptoms and whether hormone levels or their change might explain the association of menopausal status with depressive symptoms previously reported in a national sample of midlife women. DESIGN: A longitudinal, community-based, multisite study of menopause. Data were collected at baseline and annually from December 1995 to January 2008 on a range of factors. Early follicular phase serum samples were assayed for levels of estradiol, follicle-stimulating hormone, testosterone, and dehydroepiandrosterone sulfate. SETTING: Seven communities nationwide. PARTICIPANTS: A community-based sample of 3302 multiethnic women, aged 42 to 52 years, still menstruating and not using exogenous reproductive hormones. Main Outcome Measure Depressive symptoms assessed with the Center for Epidemiological Studies Depression Scale (CES-D). The primary outcome was a CES-D score of 16 or higher. RESULTS: In multivariable random-effects logistic regression models, log-transformed testosterone level was significantly positively associated with higher odds of a CES-D score of 16 or higher (odds ratio = 1.15; 95% confidence interval, 1.01-1.31) across 8 years, and a larger increase in log-transformed testosterone from baseline to each annual visit was significantly associated with increased odds of a CES-D score of 16 or higher (odds ratio = 1.23; 95% confidence interval, 1.04-1.45). Less education, being Hispanic, and vasomotor symptoms, stressful life events, and low social support at each visit were each independently associated with a CES-D score of 16 or higher. No other hormones were associated with a CES-D score of 16 or higher. Being perimenopausal or postmenopausal compared with being premenopausal remained significantly associated with a CES-D score of 16 or higher in all analyses. CONCLUSIONS: Higher testosterone levels may contribute to higher depressive symptoms during the menopausal transition. This association is independent of menopausal status, which remains an independent predictor of higher depressive symptoms.

Hydroxychloroquine and glycemia in women with rheumatoid arthritis and systemic lupus erythematosus.

OBJECTIVE: To determine the relationship between current hydroxychloroquine (HCQ) use and 2 indicators of glycemic control, fasting glucose and insulin sensitivity, in nondiabetic women with systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA). METHODS: Nondiabetic women with SLE (n = 149) or RA (n = 177) recruited between 2000 and 2005 for a cross-sectional evaluation of cardiovascular risk factors were characterized by HCQ usage status. Unadjusted and multivariately adjusted mean fasting glucose, median insulin, and insulin resistance [assessed by the homeostasis model assessment (HOMA-IR) calculation] were compared among HCQ users and nonusers for disease-specific groups. RESULTS: More women with SLE were taking HCQ than those with RA (48% vs 18%; p < 0.0001; mean dose ~ 400 mg vs ~ 200 mg). For women with SLE or RA, after adjustment for age, waist circumference, disease duration, prednisone dosage, C-reactive protein, menopausal status, nonsteroidal antiinflammatory drugs, and disease-specific indicators, serum glucose was lower in HCQ users than in nonusers (SLE: 85.9 vs 89.3 mg/dl, p = 0.04; RA: 82.5 vs 86.6 mg/dl, p = 0.05). In women with SLE, HCQ use also was associated with lower (log)HOMA-IR (0.97 vs 1.12, p = 0.09); in those with RA, no differences in (log)HOMA-IR were seen. HCQ usage was not associated with fasting insulin levels in either patient group. CONCLUSION: HCQ use was associated with lower fasting glucose in women with SLE or RA and also lower (log)HOMA-IR in the SLE group. The use of HCQ may be beneficial for reducing cardiovascular risk by improving glycemic control in these patients.

Are there bi-directional associations between depressive symptoms and C-reactive protein in mid-life women?

OBJECTIVE: To test whether depressive symptoms are related to subsequent C-reactive protein (CRP) levels and/or whether CRP levels are related to subsequent depressive symptoms in mid-life women. METHODS: Women enrolled in the Study of Women's Health Across the Nation (SWAN) were followed for 7years and had measures of CES-Depression scores and CRP seven times during the follow-up period. Women were pre- or early peri-menopausal at study entry and were of Caucasian, African American, Hispanic, Japanese, or Chinese race/ethnicity. Analyses were restricted to initially healthy women. RESULTS: Longitudinal mixed linear regression models adjusting for age, race, site, time between exams, and outcome variable at year X showed that higher CES-D scores predicted higher subsequent CRP levels and vice versa over a 7-year period. Full multivariate models adjusting for body mass index, physical activity, medications, health conditions, and other covariates showed that higher CRP levels at year X predicted higher CES-D scores at year X+1, p=0.03. Higher depressive symptoms predicted higher subsequent CRP levels at marginally significant levels, p=0.10. CONCLUSIONS: Higher CRP levels led to higher subsequent depressive symptoms, albeit the effect was small. The study demonstrates the importance of considering bi-directional relationships for depression and other psychosocial factors and risk for heart disease.

Qualifications of Physicians Performing Hysterectomy: The Study of Women's Health Across the Nation.

The objective of this study was to evaluate whether physicians performing hysterectomy on participants of the Study of Women's Health Across the Nation (SWAN) are adequately trained to perform this procedure. A multicenter longitudinal study of 3302 women aged 42 to 52 was conducted over 9 years of follow-up. Of the 238 women reporting hysterectomy within the United States, 165 were verified via medical record review. Information regarding training background and board certification status of the physicians performing these hysterectomies was obtained from the American Board of Medical Specialists. Complications of hysterectomy were abstracted from patients' medical records. Of the 165 physicians, 163 (98.8%) obtained board certification and 139 (84.2%) obtained their medical degrees in the United States. Ninety-eight percent of the physicians completed a residency in obstetrics and gynecology. Intra- and postoperative complications were exceedingly low. Physicians performing hysterectomies on participants of SWAN appear adequately trained to carry out this commonly performed procedure.

Racial differences in women who have a hysterectomy for benign conditions.

OBJECTIVE: To evaluate if there are racial differences between African-American and Caucasian women who have hysterectomy for benign conditions in terms of (1) presenting symptoms (prolapse, vaginal bleeding, pain, and known history of leiomyomas), (2) serum estradiol and testosterone levels at the visit before hysterectomy, and (3) uterine weight. METHODS: A multi-ethnic, multisite, community-based longitudinal cohort study of 3,302 women ages 42-52 at enrollment was conducted. During 9 years of follow-up, 203 African-American and Caucasian women reported a hysterectomy, 90 with evidence of uterine leiomyomas. Women were surveyed regarding their overall perceived health before and after hysterectomy, presenting symptoms, and their motivations for surgery. Serum estradiol and testosterone levels were measured. Uterine weight at time of hysterectomy and clinical pathology were determined via medical record abstraction. RESULTS: Previously diagnosed leiomyomas were presenting symptoms more frequently in African-American women than Caucasian women (85% vs. 63%; p = .02). African-American women had less prolapse than Caucasian women (0% vs. 10%; p = 0.04). Chronic pain was a more frequent reason for hysterectomy in African-American women than in Caucasian women (49% vs. 29%; p = .05). There were no differences between the groups in levels of estradiol or testosterone. African-American women had almost twice the uterine weight as that of Caucasian women (448 vs. 240 g; p = .0005). CONCLUSION: Racial differences in frequency of hysterectomy for benign conditions are consistent with differences in presenting symptoms, where African-American women seemingly have larger, more symptomatic fibroids.

Is brachial artery flow-mediated dilation associated with negative affect?

BACKGROUND: Trait negative affect has been implicated as a risk marker for cardiovascular disease, but the mechanisms underlying this association are uncertain. PURPOSE: Our aim was to examine associations between trait measures of anger, hostility, depression, and anxiety with endothelial dysfunction via brachial artery flow-mediated dilation (FMD), an early indicator of cardiovascular disease. METHOD: FMD was examined in 332 healthy older adults. Measures included Beck Anxiety and Depression Inventories, Cook-Medley Hostility Scale, and Spielberger State-Trait Anger Expression Inventory (Anger In, Anger Out, and Trait Anger). RESULTS: Mean age was 60.5 +/- 4.8 years; 83% of participants were Caucasian and 49% were female. FMD was greater in women compared to men (6.17% vs. 4.07%, p < 0.001). Women reported significantly greater Anxiety (p < 0.001), and men reported greater Hostility (p = 0.004). In separate multivariable linear regression models controlling for cardiovascular risk factors, plus current hormone therapy for women, smaller FMD was associated with higher Anger In for women (beta = -0.222, p = 0.04) and showed a trend with higher Hostility for men (beta = -0.082, p = 0.09). CONCLUSION: Endothelial dysfunction, as indicated by less vasodilatation of the brachial artery, is positively associated with measures of hostility and anger suppression in healthy older adults. Thus, associations between negative affect and cardiovascular health may be apparent early in the disease process.

Do carotid artery diameters manifest early evidence of atherosclerosis in women with rheumatoid arthritis?

OBJECTIVE: Given the high incidence of cardiovascular disease (CVD) in patients with rheumatoid arthritis (RA), we examined the associations between RA diagnosis and characteristics and evidence of carotid atherosclerosis. We take a unique approach by evaluating lumen and interadventitial diameters in addition to intima-media thickness and plaque. METHODS: Ninety-three women with RA were matched with 93 healthy women by age, race, and menopause status. In cross-sectional analyses, we compared common carotid artery measures between groups and examined their relationships with measures of RA severity and activity. RESULTS: Mean age was 53.3 years, and median RA duration was 14 years. Lumen diameter in patients was significantly greater than in healthy women (5.50 vs. 5.19 mm, p < 0.001), as was interadventitial diameter (6.92 vs. 6.61 mm, p < 0.001). Having RA also was independently associated with greater lumen (beta = 0.256, p < 0.01) and interadventitial (beta = 0.261, p < 0.01) diameters, after controlling for cardiovascular risk factors and intima-media thickness. Carotid intima-media thickness (0.70 vs. 0.71 mm) was similar, and the prevalence of carotid plaque in patients (21%) was higher but not statistically different from healthy women (15%). In patients with RA, we found positive associations between methotrexate dose and interadventitial diameter, between hypothyroidism and intima-media thickness, and between hypothyroidism and soluble endothelial adhesion molecule and plaque, independent of cardiovascular risk factors. CONCLUSIONS: Women with RA have increased carotid artery diameters compared with healthy women. This may reflect premature vascular aging and may be an early indicator of increased cardiovascular risk.
