Clinical Outcomes of Warfarin Initiation in Advanced Chronic Kidney Disease Patients With Incident Atrial Fibrillation

OBJECTIVES

The aim of this study was to examine the efficacy and safety of warfarin initiation following the diagnosis of atrial fibrillation (AF) in patients with late-stage chronic kidney disease (CKD) who transitioned to dialysis.

BACKGROUND

The clinical benefit of warfarin therapy for thromboprophylaxis after incident AF diagnosis in patients with late-stage CKD who are transitioning to dialysis is unknown.

METHODS

In this retrospective cohort analysis, the study population was a national cohort of 22,771 U.S. veterans with incident end-stage renal disease who developed incident AF before initiating renal replacement therapy. This study examined the association of warfarin therapy following the diagnosis of incident AF with ischemic cerebrovascular accidents (CVAs) (ischemic stroke or transient ischemic attack), ischemic CVA-related hospitalization, major bleeding events (gastrointestinal or intracranial bleeding), bleeding event-related hospitalizations, and post-dialysis, all-cause mortality in multivariable adjusted Cox regression analyses that adjusted for demographic characteristics and comorbidities.

RESULTS

The mean ± SD age of the cohort was 73.5 ± 8.8 years, 13% were African American, and the mean CHA₂DS₂-VASc score was 5.7 ± 2.1. Of the overall cohort, 6,682 (29.3%) patients were started on warfarin during the follow-up period. The hazard ratios (95% confidence intervals) for ischemic CVA, bleeding events, and death for those started on warfarin were 1.23 (1.16 to 1.30), 1.36 (1.29 to 1.44), and 0.94 (0.90 to 0.97), respectively, compared with those who received no anticoagulation. Warfarin exposure was associated with higher risk for ischemic CVA and bleeding event-related hospitalizations.

CONCLUSIONS

In patients with late-stage CKD who transitioned to dialysis, warfarin use was associated with higher risk of ischemic and bleeding events but a lower risk of mortality. Future studies such as those comparing warfarin with newer oral anticoagulant agents are needed to granularly define the net clinical benefit of anticoagulation therapy in patients with advanced CKD with incident AF.

Heart Failure Increases the Risk of Adverse Renal Outcomes in Patients With Normal Kidney Function

BACKGROUND

Heart failure (HF) is associated with poor cardiac outcomes and mortality. It is not known whether HF leads to poor renal outcomes in patients with normal kidney function. We hypothesized that HF is associated with worse long-term renal outcomes.

METHODS AND RESULTS

Among 3 570 865 US veterans with estimated glomerular filtration rate (eGFR) ≥60 mL min-1 1.73 m-2 during October 1, 2004 to September 30, 2006, we identified 156 743 with an International Classification of Diseases, Ninth Revision, diagnosis of HF. We examined the association of HF with incident chronic kidney disease (CKD), the composite of incident CKD or mortality, and rapid rate of eGFR decline (slopes steeper than -5 mL min-1 1.73 m-2 y-1) using Cox proportional hazard analyses and logistic regression. Adjustments were made for various confounders. The mean±standard deviation baseline age and eGFR of HF patients were 68±11 years and 78±14 mL min-1 1.73 m-2 and in patients without HF were 59±14 years and 84±16 mL min-1 1.73 m-2, respectively. HF patients had higher prevalence of hypertension, diabetes mellitus, cardiac, peripheral vascular and chronic lung diseases, stroke, and dementia. Incidence of CKD was 69.0/1000 patient-years in HF patients versus 14.5/1000 patient-years in patients without HF, and 22% of patients with HF had rapid decline in eGFR compared with 8.5% in patients without HF. HF patients had a 2.12-, 2.06-, and 2.13-fold higher multivariable-adjusted risk of incident CKD, composite of CKD or mortality, and rapid eGFR decline, respectively.

CONCLUSIONS

HF is associated with significantly higher risk of incident CKD, incident CKD or mortality, and rapid eGFR decline. Early diagnosis and management of HF could help reduce the risk of long-term renal complications.

Racial Differences in Association of Serum Calcium with Mortality and Incident Cardio- and Cerebrovascular Events

CONTEXT

Abnormalities in calcium metabolism may potentially contribute to the development of vascular disease. Calcium metabolism may be different in African American (AA) vs white individuals, but the effect of race on the association of serum calcium with clinical outcomes remains unclear.

OBJECTIVE

This study sought to examine race-specific associations of serum calcium levels with mortality and with major incident cardiovascular events.

DESIGN AND SETTING

This was a historical cohort study in the U.S. Department of Veterans Affairs health care facilities.

PARTICIPANTS

Participants included veterans (n = 1 967 622) with estimated glomerular filtration rate ≥ 60 mL/min/1.73 m².

MAIN OUTCOME MEASURES

The association between serum calcium levels with all-cause mortality, incident coronary heart disease (CHD), and ischemic stroke incidence was examined in multivariable adjusted Cox proportional hazards models, including an interaction term for calcium and race.

RESULTS

The association of calcium with all-cause mortality was U-shaped in both AA and white patients, but race modified the association of calcium with all-cause mortality. Compared with white patients, AA patients experienced lower risk of mortality when calcium was ≥ 8.8 mg/dL, with a statistically significant interaction (P < .001). Conversely, AA vs white race was associated with higher mortality when calcium was < 8.8 mg/dL. Calcium showed no significant association with ischemic stroke or CHD in both races; and race did not modify these associations (P = .37 and 0.11, respectively for interaction term).

CONCLUSIONS

Race modified the U-shaped association between calcium and all-cause mortality. Serum calcium is not associated with incident stroke or CHD in either AA or white patients. The race-specific difference in the association of calcium levels with mortality warrants further examination.

Association of Pre-Operative Albuminuria with Post-Operative Outcomes after Coronary Artery Bypass Grafting

The effect on post-operative outcomes after coronary artery bypass graft(CABG) surgery is not clear. Among 17,812 patients who underwent CABG during October 1,2006-September 28,2012 in any Department of US Veterans Affairs(VA) hospital, we identified 5,968 with available preoperative urine albumin-creatinine ratio(UACR) measurements. We examined the association of UACR<30, 30–299 and >=300 mg/g with 30/90/180/365-day and overall all-cause mortality, and hospitalization length >10 days, and with acute kidney injury(AKI). Mean ± SD baseline age and eGFR were 66 ± 8 years and 77 ± 19 ml/min/1.73 m², respectively. 788 patients(13.2%) died during a median follow-up of 3.2 years, and 26.8% patients developed AKI(23.1%-Stage 1; 2.9%-Stage 2; 0.8%-Stage 3) within 30 days of CABG. The median lengths of stay were 8 days(IQR: 6–13 days), 10 days(IQR: 7–14 days) and 12 days(IQR: 8–19 days) for groups with UACR < 30 mg/g, 30–299 mg/g and ≥300 mg/g, respectively. Higher UACR conferred 72 to 85% higher 90-, 180-, and 365-day mortality compared to UACR<30 mg/g (odds ratio and 95% confidence interval for UACR≥300 vs. <30 mg/g: 1.72(1.01–2.95); 1.85(1.14–3.01); 1.74(1.15–2.61), respectively). Higher UACR was also associated with significantly longer hospitalizations and higher incidence of all stages of AKI. Higher UACR is associated with significantly higher odds of mortality, longer post-CABG hospitalization, and higher AKI incidence.

Intracardiac echocardiography: clinical utility and application

Intracardiac echocardiography (ICE) broadens the spectrum of available echocardiographic techniques and provides the operator direct visualization of cardiac structures in real time. ICE has clear advantages over fluoroscopy, transthoracic echocardiography, and transesophageal echocardiography as the imaging modality of choice in the cardiac catheterization and electrophysiological laboratories. With the development of steerable phased array catheters with low frequency and Doppler qualities, there is marked improvement in visualization of left-sided structures from the right heart. Appropriate utilization of ICE is likely to maximize safety and efficacy of complex interventional procedures and may improve patient outcomes. Future advances in ICE imaging will further improve the ease of device guidance and, in combination with new imaging modalities, could dramatically improve other applications of echocardiography which may result in improved patient outcomes. This review describes the technical evolution of ICE, the use of ICE in guiding percutaneous interventional procedures and possible future applications of ICE in the ever-growing field of interventional cardiology.

Vascular changes and black hole phenomenon after coronary brachytherapy: a pathologically distinct entity

Restenosis remains an important issue even after coronary brachytherapy despite its efficacy in the treatment for in-stent restenosis. The acute and chronic changes in vascular wall are unique following brachytherapy. The restenotic tissue post coronary brachytherapy is relatively acellular and appears echolucent in intravascular ultrasound examination. This is dubbed the "black hole" phenomenon. Despite the similarity in the mode of action of brachytherapy and drug eluting stent implantation, the black hole phenomenon seems to be uncommon after drug-eluting stent implantation except in those patients who have had prior brachytherapy, bare-metal placement and after treatment of saphenous venous graft stenosis. It is possible that not all neointima in stents are created equal. We should propose that neointima be considered primary neointima if it forms after bare metal stenting, secondary neointima if it forms after CBT or DES, and perhaps tertiary if after combined CBT and DES. This type of classification may prove useful for research or clinical purposes. Almost certainly black hole phenomenon results from a modified neointima. However, we do not know whether this is the same restenotic tissue that was present before CBT but just depleted of its cellular element secondary to autolysis or a newly formed tertiary neointima? It is also not clear whether the changes in vascular wall and restenosis are similar after CBT or drug-eluting stent placement. However, there are some unique vascular changes that seem to be common after both of these procedures.

Does social support buffer functional decline in elderly patients with unipolar depression?

OBJECTIVE

This study tested whether social support protects against functional decline, either generally or selectively, in the most severely depressed elderly patients undergoing treatment for major depressive disorder.

METHOD

In a prospective cohort study design, 113 patients with incident and prevalent unipolar depression were followed for 12 months while they were undergoing naturalistic treatment. Outcome measures included performance on basic and instrumental activities of daily living; predictor variables included Hamilton Depression Rating Scale scores and four domains of informal social support. The analysis employed multivariable ordinary least squares regression models.

RESULTS

Improved scores on instrumental activities of daily living and stable scores on basic activities of daily living characterized the subjects. In adjusted analyses, instrumental social support provided marginal protection against worsening performance on instrumental activities of daily living, which were primarily a function of baseline depression severity. Large social networks, more frequent social interaction, and the perceived adequacy of social support played a modest buffering role against declines in performance on basic activities of daily living among the most depressed elderly patients.

CONCLUSIONS

Instrumental support was generally protective against worsening performance on instrumental abilities of daily living among elderly patients with recurrent unipolar depression. Subjective and structural dimensions of social support protected the most severely depressed elderly patients against the loss of basic maintenance abilities.

Disability as a function of social networks and support in elderly African Americans and Whites: the Duke EPESE 1986--1992

OBJECTIVES

We examined the association of structural and functional aspects of social relationships with change in disability, and the degree to which race modifies these associations.

METHODS

Data are from a population-based sample of 4,136 African Americans and Whites aged > or = 65 living in North CAROLINA: Disability data were collected during seven consecutive yearly interviews and summarized in two outcome measures. Measures of social relationships included five measures representing network size, extent of social interaction, and specific type of relationships, as well as instrumental and emotional support. Weighted proportional odds models were fitted to model disability as a function of baseline social network and support variables, and the interaction of each variable with follow-up time.

RESULTS

Network size and social interaction showed significant negative associations with disability risks, which did not vary by race, or as a function of time. Social interaction with friends was associated with a reduced risk for disability, but social interaction with children or relatives was not related to disability. Instrumental support was associated with a significantly increased disability risk, with a greater adverse effect among Whites than African AMERICANS: Emotional support was not associated with disability, but a protective effect for ADL disability was found after controlling for its intercorrelation with instrumental support.

DISCUSSION

The findings provide further evidence for the role of social relationships in the disablement process, although not all types of social relationships may be equally beneficial. Furthermore, these associations may be more complex than simple causal effects. There were few racial differences in the association of social relationships with disability, with the possible exception of instrumental support, which may allude to possible sociocultural differences in the experience of instrumental support exchanges.

The Spiritual History Scale in four dimensions (SHS-4): validity and reliability

The goals of this study were to develop a valid, reliable measure of lifetime religious and spiritual experience and to assess its value in explaining late-life health. Procedures included semi-structured interviews with Duke Aging Center volunteers (n = 30), followed by structured interviews of a stratified, random sample of subjects (n = 157) from the Established Populations for Epidemiologic Studies of the Elderly at Duke University. Principal components analysis suggested four factors with favorable psychometrics. Health-impaired subjects reported a history of seeking/receiving divine aid (God Helped). At every level of impairment, Lifetime Religious Social Support and current religious attendance were positively correlated. Regardless of current attendance, subjects who reported higher Lifetime Religious Social Support received more instrumental social support. Healthy behaviors were associated with both God Helped and Lifetime Religious Social Support. Cost of Religiousness predicted depressive symptoms and impaired social support. Family History of Religiousness was unrelated to late-life health. Evaluation of the Spiritual History Scale in Four Dimensions (SHS-4) across geographical settings, cultural subgroups, age cohorts, and clinical samples is warranted.

Six-month outcomes for MRI-related vascular depression

The purpose of this paper is to estimate the relative probabilities of 6-month recovery from an index episode of major depression for subjects with and without MRI-confirmed vascular brain changes. In this cohort study, 57 depressed subjects from the Duke University Mental Health Clinical Research Center (MHCRC) for Depression in Late Life who presented with MRI-related vascular and non-vascular depression were followed for 6 months, and the rates of recovery in the two risk groups were compared. Overall, the recovery rate in this sample was 57.9%. Subjects with MRI-related vascular depression demonstrated outcomes similar to subjects with non-vascular depression (crude RR = 0.67 [0.32, 1.43]). There was a trend that demonstrated that MRI-related vascular depression placed elderly subjects and subjects with first onset of depression after age 40 at increased risk of non-recovery. The study demonstrates overall no significant difference in course between patients with and without vascular depression. It also suggests that patients with vascular depression may have a different course depending on their age and age of onset of the disease.

Age of first onset of bipolar disorder: demographic, family history, and psychosocial correlates

The literature suggests that bipolar elders with early and late onset of the disorder present with different demographic, family history, and psychosocial profiles, which are less well characterized than those for elderly unipolar patients. In this cross-sectional clinical survey, we assessed subjects (n = 74) from the NIMH Clinical Research Center for the Study of Depression in Later Life at Duke University who had a consensus diagnosis of bipolar depression; the primary assessment instrument was the Duke Depression Evaluation Schedule. We found that bipolar subjects with later age of onset reported less family history of psychiatric problems, more comorbid vascular disease, and more instrumental and subjective social support. Stressful life events were more frequent among bipolar subjects with earlier age of depressive symptom onset. This study suggests that early-onset disorder may be characterized by a psychosocial component, whereas organic factors may be particularly important to late-onset bipolar disorder.

Depressive symptoms and nine-year survival of 1,001 male veterans hospitalized with medical illness

Authors examined effects of depressive symptoms on after-discharge survival of hospitalized medically ill male veterans. Psychosocial and physical health evaluations were performed on a consecutive sample of 1,001 patients ages 20-39 (16%) and 65-102 years (84%). Subjects or surviving family members were later contacted by telephone, and Cox proportional-hazards regression modeled the effects of depressive symptoms on time-to-death, controlling for demographics and social, psychiatric, and physical health. Follow-up was obtained on all 1,001 patients (average observation time, 9 years), during which 667 patients died (67%). Patients with depressive symptoms were significantly less likely to survive. For every 1-point increase on the 12-item Brief Carroll Depression Rating Scale (BCDRS), the hazard of dying increased by 10% (P<0. 0001). Age did not significantly affect the association between depressive symptoms and mortality. Depressive symptoms during acute hospitalization are a predictor of shortened survival.

Functional impairment and utilization of services associated with posttraumatic stress in the community

This study describes social functioning and service utilization patterns associated with posttraumatic stress symptoms relative to nonpsychiatric controls and depressive disorder controls in a cross-sectional epidemiological survey. Data from 49 cases and 147 controls who participated in the North Carolina component of the Epidemiologic Catchment Area study were examined. Results indicate that symptoms of posttraumatic stress were associated with impairment along several domains of functioning: social, financial, physical, and psychological. Individuals with posttraumatic stress were found to have more socioeconomic disadvantages and impaired functioning. Despite this, individuals with posttraumatic stress are receiving relatively few mental health services. Further research assessing service use, treatment, and functional outcomes are indicated.

Perceived social support among depressed elderly, middle-aged, and young-adult samples: cross-sectional and longitudinal analyses

BACKGROUND

A number of studies have concluded that the perceived quality of support is more strongly associated with mental health than with the actual structure of personal networks. This study examined clinical, historical, and phenomenological variables associated cross-sectionally and longitudinally with perceived social support.

METHODS

Participants included elderly, middle-aged, and young-adult depressed samples derived from the Duke Clinical Research Center for the Study of Depression in Late Life.

RESULTS

Cross-sectional multivariate analyses revealed that perceived social support was: (1) for the elderly associated with pessimistic thinking, being divorced, having strange ideas, the degree of social interaction, and instrumental support; (2) for middle-age associated with dysthymia, divorce, pessimistic thoughts, social interaction, and instrumental support; and (3) among young adults with instrumental support only. Longitudinal multivariate analyses indicated that only perceived social support at Time 1 predicted perceived social support 1 year later among elderly and middle-aged subjects, whereas only instrumental support predicted perceived social support 1 year later among the young-adult sample.

LIMITATIONS

The small number of subjects among the young-adult sample limit conclusions regarding this group. In addition, only patients provided data. Future studies should consider using multiple informants to enhance the accuracy of reported social support.

CONCLUSIONS

Our findings indicate that in addition to whatever else they do for depressed patients, clinicians must endeavor to address relationship or social support difficulties, especially in the elderly.

Does religious attendance prolong survival? A six-year follow-up study of 3,968 older adults

METHODS

A probability sample of 3,968 community-dwelling adults aged 64-101 years residing in the Piedmont of North Carolina was surveyed in 1986 as part of the Established Populations for the Epidemiologic Studies of the Elderly (EPESE) program of the National Institutes of Health. Attendance at religious services and a wide variety of sociodemographic and health variables were assessed at baseline. Vital status of members was then determined prospectively over the next 6 years (1986 1992). Time (days) to death or censoring in days was analyzed using a Cox proportional hazards regression model.

RESULTS

During a median 6.3-year follow-up period, 1,777 subjects (29.7%) died. Of the subjects who attended religious services once a week or more in 1986 (frequent attenders), 22.9% died compared to 37.4% of those attending services less than once a week (infrequent attenders). The relative hazard (RH) of dying for frequent attenders was 46% less than for infrequent attenders (RH: 0.54, 95% CI 0.48-.0.61), an effect that was strongest in women (RH 0.51, CI 0.434).59) but also present in men (RH 0.63, 95% CI 0.52-0.75). When demographics, health conditions, social connections, and health practices were controlled, this effect remained significant for the entire sample (RH 0.72, 95% CI 0.64-.81), and for both women (RH 0.65, 95% CI 0.554-.76, p<.0001) and men (RH 0.83, 95% CI 0.69-1.00, p=.05).

CONCLUSIONS

Older adults, particularly women, who attend religious services at least once a week appear to have a survival advantage over those attending services less frequently.

Disability and depressive symptoms in the elderly: the effects of instrumental support and its subjective appraisal

This article explores the buffering effect of social support on depressive symptoms in a community sample of elderly with varying levels of disability. Baseline interviews were conducted in respondents' homes. Results show that higher levels of disability are associated with higher levels of depression. Instrumental support and subjective appraisal of the network are associated with depressive symptoms, but instrumental support has a weak positive correlation, while subjective appraisals show a negative relationship. Social support mitigates the depressive effect of disability only when the network's efforts are appraised positively. However, no such relationship is shown for instrumental support. One's perception of the network's helpfulness appears to be more potent than the actual help provided by friends and family.

Racial and psychosocial risk factors for herpes zoster in the elderly

The effects of black race and psychologic stress on the risk of acquiring herpes zoster in late life were examined. Subjects were participants of a stratified probability sample of community-dwelling persons > or = 65 years old. A comprehensive health survey was administered in 1986-1987 (P1), 1989-1990 (P2), and 1992-1994 (P3). Incident cases of zoster between P1 and P2 and P2 and P3 served as the dependent variables. Hypothesis-testing variables included race, negative life events, and measures of social support. Control variables included age, sex, education, cancer, other chronic diseases, hospitalization, activities of daily living, self-rated health, depression, and cigarette smoking. From P1 to P2, 1.4% of black and 3.4% of white subjects developed zoster (P < .001). From P2 to P3, 2.9% of black and 7.5% of white subjects developed zoster (P < .001). After controlling for variables, black subjects were significantly less likely to develop zoster than were white subjects (adjusted odds ratio, 0.37; 95% confidence interval, 0.26, 0.53; P = .0001). Most measures of stress were not significantly related to zoster; however, study limitations preclude definitive conclusions.

The relationship between religious activities and cigarette smoking in older adults

BACKGROUND

The objective of this study was to examine the relationship between religious activities and cigarette smoking in community-dwelling older adults.

METHODS

Cigarette smoking and religious activities were assessed in a probability sample of 3968 persons age 65 years or older participating in the Duke Populations for Epidemiologic Studies of the Elderly (EPESE) survey. Participants were asked if they currently smoked, if they ever smoked, and how many cigarettes per day they smoked. Attendance at religious services, participation in private religious activities (prayer or Bible study), and use of religious media (religious TV or radio) were also assessed. Data were available for Waves I-III of the survey (1986, 1989, and 1992). Analyses were controlled for age, race, sex, education, alcohol use, physical health, and in the longitudinal analyses, smoking status at prior waves.

RESULTS

Cross-sectional analyses revealed that participants who frequently attended religious services were significantly less likely to smoke cigarettes at all three waves. Likewise, elders frequently involved in private religious activity were less likely to smoke (Waves II and III). Total number of pack-years smoked was also inversely related to both attendance at religious services and private religious activities. Watching religious TV or listening to religious radio, on the other hand, was not related to smoking at Waves I and II nor to total pack-years smoked, but was positively related to current smoking at Wave III. Among those who smoked, number of cigarettes smoked was inversely related to frequency of attendance at religious services (Wave I), private religious activities (Wave III), and religious TV/radio (Waves II and III). Retrospective and prospective analyses revealed that religiously active persons were less likely to ever start smoking, not more likely to quit smoking.

CONCLUSIONS

Religiously active persons are less likely to smoke cigarettes, and if they do smoke, smoke fewer cigarettes. Given the association between smoking and disease, and the widespread prevalence of both smoking and religious activity, this finding has implications for public health.

The relationship between religious activities and blood pressure in older adults

OBJECTIVE

To examine the relationship between religious activities and blood pressure in community-dwelling older adults.

METHOD

Blood pressure and religious activities were assessed in a probability sample of 3,963 persons age sixty-five years or older participating in the Duke EPESE survey. Participants were asked if their doctor had ever informed them that they had high blood pressure and if they were currently taking medication for high blood pressure. After the interview, systolic and diastolic blood pressure were measured following a standardized protocol. Data were available for three waves of the survey (1986, 1989-90, and 1993-94). Analyses were stratified by age (65-74 vs. over 75) and by race (Whites vs. Blacks) and were controlled for age, race, gender, education, physical functioning, body mass index, and, in longitudinal analyses, blood pressure from the previous wave.

RESULTS

Cross-sectional analyses revealed small (1-4 mm Hg) but consistent differences in measured systolic and diastolic blood pressures between frequent (once/wk) and infrequent (< once/wk) religious service attenders. Lower blood pressures were also observed among those who frequently prayed or studied the Bible (daily or more often). Blood pressure differences were particularly notable in Black and younger elderly, in whom religious activity at one wave predicted blood pressures three years later. Among participants who both attended religious services and prayed or studied the Bible frequently, the likelihood of having a diastolic blood pressure of 90 mm Hg or higher was 40 percent lower than found in participants who attended religious services infrequently and prayed or studied the Bible infrequently (OR 0.60, 95% CI, 0.48-0.75, p < .0001). Among participants told they had high blood pressure, religiously active persons were more likely to be taking their blood pressure medication; this could not, however, explain the differences in blood pressure observed. While most religious activity was associated with lower blood pressure, those who frequently watched religious TV or listened to religious radio actually had higher blood pressures.

CONCLUSIONS

Religiously active older adults tend to have lower blood pressures than those who are less active. This applies to attendance at religious services and private religious activities, but not to religious media. Physiological mechanisms are discussed.

Depression and social support in elderly patients with cardiac disease

BACKGROUND

Depression is common among patients with cardiac disease. A number of psychosocial factors may affect the relationship between physical health and depression. There is evidence from the psychiatric literature suggesting that negative life events and social support are important factors in the development and outcome of depression. It is unknown if these factors are important in the context of depression in medically ill patients. Thus it is important to examine the relationship among social support, negative life events, and the presence of depression in elderly patients with cardiac disease.

METHODS

Patients with coronary artery disease were assessed with the Duke Depression Evaluation Schedule for the Elderly. This includes the mood and anxiety disorder section of the Diagnostic Interview Schedule modified for Diagnostic and Statistical Manual of Mental Disorders diagnoses, life events, and multidimensional assessment of social support. Two hypotheses were tested: (1) the number of concurrent negative life events will be higher in patients with coronary artery disease with major depression than those without depression, and (2) social support will be less in patients with major depression than in those without.

RESULTS

Presence of major depression was associated with increased negative life events and lowered subjective social support after accounting for age, sex, and race.

CONCLUSIONS

The finding that subjective social support and negative life events are related to major depression suggests that even in the context of medical illness, social factors are still important in the development of major depression.

Race and stress in the incidence of herpes zoster in older adults

OBJECTIVES

To examine the effect of black race and acute (negative life events) and chronic (lack of social support) psychological stress on the risk of herpes zoster in late life.

DESIGN

A population-based, prospective cohort study.

SETTING

Central North Carolina.

PARTICIPANTS

Duke Established Populations for Epidemiological Studies of the Elderly, a stratified probability sample of community-dwelling persons more than 65 years of age.

MEASUREMENTS

Interviewers administered a comprehensive health survey to the participants in 1986-1987 (P1, n = 4162), 1989-1990 (P2, n = 3336), and 1992-1994 (P3, n = 2568). Incident cases of zoster between P1 and P2 and P2 and P3 served as the dependent variable. Hypothesis-testing variables included race, negative life events, and five measures of social support. Control variables included age, sex, education, cancer, chronic diseases, basic ADLs, instrumental ADLs, depression, self-rated health, hospitalization, and cigarette smoking. Statistical analyses employed chi-square tests and proportional hazards model.

RESULTS

At baseline, the sample had a mean age of 73.6 years and was 55% black, 45% white, and 65% female. There were 65 cases of zoster between P1 and P2 and 102 cases of zoster between P2 and P3. From P1 to P2, 1.4% of blacks and 3.4% of whites developed zoster (P < .001). From P2 to P3, 2.9% of blacks and 7.5% of whites developed zoster (P < .001). After controlling for the above variables, blacks were significantly less likely to develop zoster (adjusted risk ratio = 0.35; 95% confidence interval (CI), 0.24-0.51; P < .001). Negative life events increased the risk of zoster, but the result was borderline for statistical significance (adjusted RR = 1.38, 95% CI 0.96-1.97; P = .078). No measures of social support were significantly associated with zoster.

CONCLUSION

Black race decreased the risk of zoster in late life significantly. Measures of stress were not significantly related to zoster, but study limitations preclude definitive conclusions. Future research should focus on these factors in larger samples and different populations.

Depression and physical disability outcomes in depressed medically ill hospitalized older adults

The authors examined depression/disability outcomes in hospitalized older medical patients during the year after hospital discharge to assess the pattern and rate of changing depression and disability, the causal relationship between these variables, and to identify patients at greatest risk for poor outcomes. A group of 119 medical patients at Duke Hospital were both depressed and disabled; they were followed for a median of 47 weeks after hospital discharge. Time-series analyses showed that depression and disability tended to track together, and most changes occurred within the first 6 months after discharge. Blacks were more likely to remit from depression despite continued disability and less likely to experience continued depression despite decreased disability. Patients with a history of depression were less likely to experience improvement in depression unless disability improved. Number of medical diagnoses and depression severity independently predicted poorer depression outcomes. Certain characteristics of patients during hospitalization predict depression/disability outcomes after discharge.

Attendance at religious services, interleukin-6, and other biological parameters of immune function in older adults

OBJECTIVE

First, to examine and explain the relationship between religious service attendance and plasma Interleukin-6 (IL-6) levels, and second, to examine the relationship between religious attendance and other immune-system regulators and inflammatory substances.

METHODS

During the third in-person interview (1992) of the Establishment of Populations for Epidemiologic Studies of the Elderly (EPESE) project, Duke site, 1718 subjects age sixty-five or over had blood drawn for analysis of immune regulators and inflammatory factors, including IL-6 measurements. IL-6 was examined both as a continuous variable and at a cutoff of 5 pg/ml. Information on attendance at religious services was available from the 1992 interview and two prior interviews (1986 and 1989).

RESULTS

Religious attendance was inversely related to high IL-6 levels (> 5 pg/ml), but not to IL-6 measured as a continuous variable. Bivariate analyses revealed that high religious attendance in 1989 predicted a lower proportion of subjects with high IL-6 in 1992 (beta-.10, p = .01) High religious attendance in 1992 also predicted a lower proportion of subjects with high IL-6 levels in 1992 (beta-.14, p = .0005). When age, sex, race, education, chronic illnesses, and physical functioning were controlled, 1989 religious attendance weakened as a predictor of high IL-6 (beta-.07, p = .10), but 1992 religious attendance retained its effect (beta-.10, p = .02). When religious attenders were compared to non- attenders, they were only about one-half as likely to have IL-6 levels greater than 5 ng/ml (OR 0.58, 95% CI 0.40-0.84, p < .005). Religious attendance was also related to lower levels of the immune-inflammatory markers alpha-2 globulin, fibrin d-dimers, polymorphonuclear leukocytes, and lymphocytes. While controlling for covariates weakened most of these relationships, adjusting analyses for depression and negative life events had little effect.

CONCLUSIONS

There is a weak relationship between religious attendance and high IL-6 levels that could not be explained by other covariates, depression, or negative life events. This finding provides some support for the hypothesis that older adults who frequently attend religious services have healthier immune systems, although mechanism of effect remains unknown.

Administrative update: utilization of services. I. Comparing use of public and private mental health services: the enduring barriers of race and age

Data from the NIMH-Epidemiologic Catchment Area Project were used to predict differential use of private versus public outpatient mental health services, a salient concern in integrating public and private services in market-based health care reform efforts. Having a recent psychiatric disorder, being age 25-44, female, white, of higher educational level, and unmarried increase the odds of any mental health service use. However, odds of treatment in the public sector are increased for males, African Americans, those with low educational and income levels, and odds are markedly decreased for the elderly, suggesting significant barriers to care for these mentally ill subpopulations.

Religiosity and remission of depression in medically ill older patients

OBJECTIVE

The effects of religious belief and activity on remission of depression were examined in medically ill hospitalized older patients.

METHOD

Consecutive patients aged 60 years or over who had been admitted to medical inpatient services at a university medical center were screened for depressive symptoms. Of 111 patients scoring 16 or higher on the Center for Epidemiologic Studies Depression Scale, 94 were diagnosed with depressive disorder (DSM-III major depression or subsyndromal depression) by a psychiatrist using a structured psychiatric interview. After hospital discharge, depressed patients were followed up by telephone at 12-week intervals four times. At each follow-up contact, criterion symptoms were reassessed, and changes in each symptom over the interval since last contact were determined. The median follow-up time for 87 depressed patients was 47 weeks. Religious variables were examined as predictors of time to remission by means of a multivariate Cox model, with controls for demographic, physical health, psychosocial, and treatment factors.

RESULTS

During the follow-up period, 47 patients (54.0%) had remissions; the median time to remission was 30 weeks. Intrinsic religiosity was significantly and independently related to time to remission, but church attendance and private religious activities were not. Depressed patients with higher intrinsic religiosity scores had more rapid remissions than patients with lower scores.

CONCLUSIONS

In this study, greater intrinsic religiosity independently predicted shorter time to remission. To the authors' knowledge, this is the first report in which religiosity has been examined as a predictor of outcome of depressive disorder.

Social correlates of the dimensions of depression in the elderly

Few investigations of the social correlates of depressive symptomatology have addressed variation in the correlates across multiple dimensions of depression scales. We examined the relationships of selected social, clinical, and demographic correlates with four dimensions of the Center for Epidemiologic Studies-Depression (CES-D) scale in 3,401 community-dwelling elders in the Piedmont area of North Carolina. These correlates explained significant variation in somatic complaints and depressed affect; effects of chronic disability and recent negative events were particularly robust. Having a confidant explained reduced symptomatology for all four dimensions, but particularly for low positive affect and interpersonal problems. Positive affect was also buttressed by helping others. These patterns have particular relevance where treatment for depression is divorced from considerations of the social environment of the elderly patient.

Sexual assault history and health perceptions: seven general population studies

This article uses data from 7 population surveys to evaluate the association of sexual assault history with health perceptions. It estimates the extent of generalizability across gender, ethnic groups, and studies; the extent to which depression accounts for or mediates the association; and whether some circumstances of assault are more strongly related to poor subjective health. Data from each of 18 subsamples of the surveys were analyzed (pooled N = 10,001; 7,550 women and 2,451 men), and results were combined by using meta-analysis. Assault was associated with poor subjective health (odds ratio [OR] = 1.63, 95% confidence interval [CI] = 1.36, 1.95) and this result was consistent regardless of gender, ethnicity, or sample. Controlling depression did not markedly change this result (OR = 1.46, 95% CI = 1.21, 1.77), indicating that depression did not account for or mediate the assault-health perceptions association. Multiple assaults and assaults by strangers or spouse were most strongly associated with poor subjective health.

Psychosocial and physical correlates of chronic depression

This study used a case-control design to address differences in psychosocial, physical and clinical profiles between subjects who presented with a chronic index episode of major depression and those who presented with a non-chronic index episode. Subjects were adult patients participating in the Duke University Mental Health Clinical Research Center (MHCRC) for the Study of Depression in Later Life. Cases (N = 88) who reported duration of depressive symptoms lasting > or = 24 months at enrollment were compared to controls (N = 354) who reported symptoms lasting 1-12 months. The groups were compared with respect to selected demographic and clinical variables, physical function deficits, medical comorbidity, social support constructs and number of recent stressful life events. Social support and physical health were more relevant to chronicity of major depressive illness than were severity of illness or family history. Older age (> 60 years) intensified the deleterious effect of recent negative life events and reduced the deleterious effect of functional impairment on chronic major depression. These findings require special emphasis where treatment for chronic major depression is divorced from considerations of the social environment and functional capacity.

Use of antidepressants by nonpsychiatrists in the treatment of medically ill hospitalized depressed elderly patients

OBJECTIVE

The purpose of this study was to examine antidepressant use by nonpsychiatrists in the treatment of depressed elderly medical inpatients.

METHOD

Patients aged 60 or older who were admitted to medical services at Duke Hospital were evaluated by a geropsychiatrist who used a structured psychiatric interview to identify major or minor depressive disorder. Medical records of depressed patients were reviewed for use of antidepressants and benzodiazepines before admission, during hospitalization, and on discharge. After discharge, depressed patients were contacted four times by telephone at 12-week intervals to inquire about medication use (median follow-up time = 45 weeks).

RESULTS

Of 153 depressed patients, 40.5% received antidepressants at some time during their hospital stay or follow-up period, 25.5% received only benzodiazepines, and 34.0% received neither. The most commonly prescribed antidepressant was amitriptyline (45.2% of treated patients), administered at an average maximum dose of 49 mg/day. Only 15 of 114 untreated depressed patients started antidepressant therapy during hospitalization (nine with amitriptyline). Of 91 depressed patients who did not receive antidepressants either before admission or during hospitalization, only 11% received any antidepressant therapy during the median 11-month follow-up; again, half were treated with amitriptyline at doses of 10-30 mg/day. Intensity of antidepressant therapy was predicted by severity of depressive symptoms, history of psychiatric problems, and higher income.

CONCLUSIONS

A relatively low proportion of depressed older medical inpatients receive treatment with antidepressants. Patients treated with antidepressants often receive potentially dangerous tertiary tricyclics at inadequate doses. Unless depression is identified and treated during medical hospitalization, it is unlikely to be treated adequately after discharge.

Depression in medically ill hospitalized older adults: prevalence, characteristics, and course of symptoms according to six diagnostic schemes

OBJECTIVE

The purpose of this study was to examine and compare rates of depression, correlates, and course of symptoms in medically ill hospitalized elders through use of six diagnostic schemes (inclusive, etiologic, exclusive-inclusive, exclusive-etiologic, substitutive-inclusive, and substitutive-etiologic).

METHOD

A consecutive series of 460 cognitively unimpaired patients aged 60 or over who were admitted to the medical inpatient services of Duke Hospital underwent a structured psychiatric evaluation administered by a psychiatrist. Patients with depression were contacted by telephone at 12-week intervals after discharge to assess weekly change in depressive symptoms (median follow-up time = 47 weeks).

RESULTS

The prevalence of major depression varied from 10% to 21% depending on diagnostic scheme; similarly, minor depression varied from 14% to 25%. Diagnostic strategy made little difference in known psychological and health characteristics of patients with depression (predictive validity) or severity of depressive symptoms (convergent validity). The diagnostic strategy that best distinguished a severe and persistent major depression was the exclusive-etiologic approach; however, this strategy missed 49% of patients with major depression identified by the inclusive approach, almost 60% of whom continued to experience persistent symptoms of depression many weeks after discharge.

CONCLUSIONS

Diagnostic strategy affects rates of major and minor depression, with about a twofold difference between the extremes. There is little reason, however, to choose one diagnostic scheme over another in all cases. Diagnostic strategy should be chosen on the basis of the specific goals and purposes of the examiner. While the exclusive-etiologic approach identifies the most severe and persistent depressions, the inclusive approach is the most sensitive and reliable approach and is an intermediate predictor of persistent depression.

Interpreting the effectiveness of involuntary outpatient commitment: a conceptual model

Many experimental trials of community mental health interventions fail to develop testable conceptual models of the specific mechanisms and pathways by which relevant outcomes may occur, thus falling short of usefully interpreting what happens inside the experimental "black box." This paper describes a conceptual model of involuntary outpatient commitment (OPC) for persons with severe and persistent mental disorders. The model represents an attempt to "unpack" the effects of OPC by incorporating several interacting variables at various stages. According to this model, court-mandated outpatient treatment may improve long-term outcomes both directly and indirectly in several ways: by stimulating case management efforts, mobilizing supportive resources, improving individual compliance with treatment in the community, reducing clients' psychiatric symptoms and dangerous behavior, improving clients' social functioning, and finally by reducing the chance of illness relapse and rehospitalization. A randomized clinical trial of OPC is underway in North Carolina that will test the direct and indirect effects suggested by this model, using longitudinal data from the multiple perspectives of mental health clients, family members, and case managers.

The ethical challenges of a randomized controlled trial of involuntary outpatient commitment

Involuntary outpatient commitment (OPC) is a civil justice procedure intended to enhance compliance with community mental health treatment, to improve functioning, and to reduce recurrent dangerousness and hospital recidivism. The research literature on OPC indicates that it appears to improve outcomes in rates of rehospitalization and length of stay. However, all studies to date have serious methodological limitations because of selection bias; lack of specification of target populations; unclear operationalization of OPC; unmeasured variability in type, frequency, and intensity of treatment; as well as other confounding factors. To address limitations in these studies, the authors designed a randomized controlled trial (RCT) of OPC, combined with community-based case management, which is now under way in North Carolina. This article describes ethical dilemmas in designing and implementing an RCT of a legally coercive intervention in community-based settings. These ethical dilemmas challenge the experimental validity of an RCT but can be successfully addressed with careful planning and negotiation.

Sociodemographic and clinical correlates of number of previous depressive episodes in the depressed elderly

Age of onset has been used as a correlate of depressive symptomatology in the elderly. Examining frequency of episodes may improve our ability to make such correlations. The authors studied variations in an index presentation of depression in late life based on the number of previous depressive episodes. Having more than two previous episodes (as compared to two or less) was related to younger age, early age of onset, dysthymia, feelings of worthlessness, difficulty concentrating, slowed thoughts, suicidal ideation, generalized anxiety, and decreased perceptions of social support. In a logistic regression model, significant predictors of more than two previous episodes were young age, early age of onset, dysthymia, suicidality, and lower perceived social support. Patients with many episodes may be at higher risk for more severe illness and may require more aggressive treatment.

Effects of gender and ethnic group on blood pressure control in the elderly

In order to determine the adequacy of blood pressure treatment in black and white elderly men and women, the authors performed a cross-sectional population survey in Central North Carolina in 1986-1987. Participants included a random sample of noninstitutionalized individuals age 65 years or older. Blacks were oversampled. A health questionnaire was administered, and blood pressure was measured. Of 5,223 eligible persons, 4,162 (80%) participated. Fifty-four percent of subjects were black and 65% were women. Sixteen percent of the study subjects were white men, 30% white women, 19% black men, and 35% black women. The mean age was 73 years. Fifty-three percent had hypertension. Among hypertensives, 80.8% were taking blood pressure medication. Among treated hypertensives, blood pressure was adequately controlled, (measured diastolic blood pressure of 90 mm Hg or lower) in 85.6%. Women were 52% more likely than men and blacks were 40% less likely than whites to exhibit adequate blood pressure control. Older age and smoking were also associated with better blood pressure control. The authors conclude that hypertension is more likely to be controlled in elderly women than men and less likely to be well-controlled in elderly blacks than whites. The choice of antihypertensive agent may also be important. Further investigation is needed into the mechanisms accounting for the observed sex and race differences.

The association of sexual assault and attempted suicide within the community

BACKGROUND

Lifetime community rates of attempted suicide were compared between those who reported a history of sexual assault and a control group without such a history.

METHODS

The 2918 respondents in the Duke University Epidemiological Catchment Area Study were placed into groups with reported sexual assault (n = 67) and those with no known history of such (n = 2851). Multivariate and bivariate procedures were used to examine the relation between sexual assault and attempted suicide.

RESULTS

Subjects reporting a history of sexual assault were more likely to be female, younger, and to report higher rates of lifetime suicide attempt and post-traumatic stress symptoms; no differences were found in the number of chronic medical disorders, major depression, substance abuse or substance dependence, or panic attacks. Nine (14.9%) of the 67 index group subjects reported a suicide attempt, 4 of whom reported their first sexual assault as occurring before age 16 years. A sexual assault history was associated with increased prevalence of lifetime suicide attempt after controlling for sex, age, education, posttraumatic stress symptoms, and psychiatric disorder. Findings were similar in the female-only subsample (n = 1778). For women, the odds of attempting suicide was 3 to 4 times greater when the first reported sexual assault occurred prior to age 16 years compared with age 16 years or older.

CONCLUSIONS

Sexual assault is associated with an increased lifetime rate of attempted suicide. In women, a history of sexual trauma before age 16 years is a particularly strong correlate of attempted suicide.

Missing links: the case for a social psychology of the life course

The major purpose of this discussion is to demonstrate that the knowledge base has suffered as a result of insufficient cross-fertilization of social-psychological and life course/aging perspectives. The central focus of the article is identification of research issues of interest to life course and aging scholars that would be enriched by increased attention to social-psychological principles and, conversely, identification of social-psychological research topics that would be advanced by increased attention to life course and aging issues.

Clinical and phenomenological comparisons of late-onset and early-onset depression

OBJECTIVE

The authors examined the relationship between age at onset of first depressive episode and clinical features in elderly depressed patients.

METHOD

They used data on age at onset and clinical features in 246 elderly depressed patients treated at the National Institute of Mental Health Clinical Research Center for the Study of Depression in Later Life, located at Duke University.

RESULTS

Two variables--loss of interest and number of depressive episodes--were related to age at onset in all analyses.

CONCLUSIONS

This study confirms the hypothesis that apathy is more prominent in late-onset than in early-onset depression.

New directions in research on involuntary outpatient commitment

OBJECTIVE

Involuntary outpatient commitment has been used as a method of improving tenure in community programs for individuals with severe and persistent mental illness. This paper reviews literature on research about involuntary outpatient commitment and suggests questions and methods for future research.

METHODS

Literature describing research studies of involuntary outpatient commitment, located by searching MEDLINE and following up references cited in relevant articles, was reviewed with attention to patient characteristics and diagnostic, treatment, and outcomes measures.

RESULTS

Involuntary outpatient commitment appears to provide limited but improved outcomes in rates of rehospitalization and lengths of hospital stay. Variability in community treatment makes interpretation of other types of outcome difficult. Few studies specifically identify results among patients with severe and persistent mental illness.

CONCLUSIONS

No studies have examined the extent to which outpatient commitment affects compliance and treatment when essential community services such as case management are consistently and aggressively provided, nor have studies controlled for potentially confounding factors such as treatment and nontreatment effects, including informal coercion. A randomized trial of involuntary outpatient commitment should be useful in evaluating the effectiveness of this type of intervention.

Racial differences in the occurrence of herpes zoster

The purpose of this study was to determine if there are racial differences in the occurrence of herpes zoster (shingles). The study population was the Duke Established Populations for Epidemiologic Studies of the Elderly, a probability sample of community-dwelling persons > 64 years old in North Carolina. Interviewers administered a comprehensive health survey to the participants that included questions about lifetime occurrence of shingles. Of the 3206 subjects, 316 (9.9%) had had zoster: 81 (4.5%) of 1754 blacks and 235 (16.1%) of 1452 whites had had shingles (P < .0001). After controlling for age, cancer, and demographic factors, blacks remained one-fourth as likely as whites (adjusted odds ratio 0.25, 95% confidence interval 0.18-0.35; P = .0001) to have experienced zoster. In summary, blacks had a significantly lower risk of developing herpes zoster than whites, a new finding in herpes zoster epidemiology.

Hospital stressors experienced by elderly medical inpatients: developing a Hospital Stress Index

OBJECTIVE

To develop a long and short version of an index to measure experiences during hospitalization perceived by elderly patients as stressful.

SAMPLES AND METHODS

Consecutive patients aged sixty or over admitted to a university teaching hospital were assessed for hospital-related stressors during two separate studies. In the first study, seventy-six patients were asked an open-ended question exploring what they found most stressful about being in the hospital. Responses were grouped into major categories, and questions were developed to address concerns in each category; the resulting forty items were called the Hospital Stress Index (HSI). The HSI was then administered to a separate group of ninety-two patients; data were also collected on functional disability (impaired ADLs), dysfunctional attitudes (DAS), and depressive symptoms (CES-D).

RESULTS

Spontaneously reported hospital stressors were grouped into seven categories: 1) adverse effects of diagnostic or therapeutic procedures/treatments, 2) forced life-style changes, 3) relationships with staff, 4) individual psychiatric issues, 5) understanding diagnosis/prognosis, 6) family issues, and 7) the physical environment. The largest category of stressors concerned relationships with doctors and nurses. High HSI scores were significantly more common among Whites than Blacks and among patients with high CES-D, high DAS, or impaired ADLs scores. A number of potentially modifiable hospital-related stressors and individual patient issues were identified. Finally, an abbreviated fifteen-item HSI was developed to maximize patient discriminability, highlight individual differences, and enhance the detection of modifiable stressors.

CONCLUSIONS

Hospital-reported stressors may contribute to the emotional distress that elderly inpatients experience. We have developed an index to identify such stressors.

Psychological adjustment of children with sickle cell disease: stability and change over a 10-month period

Rates of poor psychological adjustment of children with sickle cell disease remained relatively constant over initial and follow-up assessment points. However, there was relatively little stability in the classification of the adjustment of individuals, low congruence in specific behavior problem patterns and diagnoses in accordance with the Diagnostic and Statistical Manual of Mental Disorders (3rd ed.; American Psychiatric Association, 1980), and less stability in child adjustment by child report than by mother report. With initial levels of adjustment controlled, children's strategies for coping with pain accounted for a significant increment in child-reported symptoms (19%) and mother-reported internalizing behavior problems (8%) at follow-up beyond the contribution of illness and demographic parameters and follow-up interval. The findings suggest that children's coping strategies are a salient intervention target for enhancing adjustment.

The relationship between insurance coverage and psychiatric disorder in predicting use of mental health services

OBJECTIVE

This study investigated how insurance coverage for mental health services affects outpatient mental health service utilization among those with and among those without a DSM-III psychiatric diagnosis. The authors used a representative community sample to compare the regression effects of insurance coverage on utilization of mental health services among these subjects.

METHOD

Data are from the second wave of the Piedmont, North Carolina, site of the Epidemiologic Catchment Area project. These data contain DSM-III diagnostic measures derived from the National Institute of Mental Health Diagnostic Interview Schedule as well as measures of insurance coverage and utilization. Responses from 2,889 community residents were analyzed using both ordinary least squares and logistic regression.

RESULTS

In both models, insurance coverage was strongly associated with care among those with as well as among those without a psychiatric disorder. The association between coverage and the probability of care was strongest among those with a disorder.

CONCLUSIONS

The findings are not consistent with the claim that failing to provide insurance coverage will reduce discretionary but not necessary mental health care utilization. They provide evidence that failing to provide insurance coverage will reduce utilization as much or more among those with a psychiatric disorder as among those without. This result has important implications for health care reform.
