Abstract
OBJECTIVES Adiponectin levels are inversely related to cardiovascular risk and are low in diabetics and obese persons. We examined the association between adiponectin concentration and HIV-associated lipodystrophy, which remains unclear. METHODS The Study to Understand the Natural History of HIV/AIDS in the Era of Effective Therapy (SUN) was a prospective cohort study of HIV-infected adults conducted in four US cities. Lean body and fat masses were assessed using dual-energy X-ray absorptiometry scans. Using baseline data from 2004 to 2006, we defined lipodystrophy using a sex-specific fat mass ratio and performed cross-sectional analyses of associated risks using multivariable logistic regression. RESULTS Among 440 male participants (median age 42 years; 68% non-Hispanic white; 88% prescribed combination antiretroviral therapy; median CD4 lymphocyte count 468 cells/μL; 76% with viral load < 400 HIV-1 RNA copies/mL; 5% diabetic; median body mass index 25 kg/m2 ), median concentrations of leptin and adiponectin were 3.04 ng/L [interquartile range (IQR) 1.77-5.43 ng/L] and 8005 μg/mL (IQR 4950-11 935 μg/mL), respectively. The prevalence of lipodystrophy was 14%. Lipodystrophy was significantly associated with increasing age [prevalence ratio (PR) 1.50; 95% confidence interval (CI) 1.10-2.06, per 10 years], adiponectin < 8005 μg/mL (PR 5.02; 95% CI 2.53-9.95), ever stavudine use (PR 2.26; 95% CI 1.36-3.75), CD4 cell count > 500 cells/μL (PR 2.59; 95% CI 1.46-4.61), viral load < 400 copies/mL (PR 3.98; 95% CI 1.25-12.6), highly sensitive C-reactive protein < 1.61 mg/L (PR 1.91; 95% CI 1.11-3.28) and smoking (PR 0.42; 95% CI 0.22-0.78). CONCLUSIONS Among men in this HIV-infected cohort, the prevalence of lipodystrophy was similar to previous estimates for persons living with HIV, and was associated with lower adiponectin levels, potentially indicating increased cardiovascular disease risk.

Abstract
OBJECTIVES To determine the prevalence of pre-frailty among HIV-infected persons and associations with pre-frailty and frailty in this population. DESIGN, SETTING AND PARTICIPANTS From a contemporary, prospective observational cohort of HIV-infected persons (SUN Study), we determined, using a cross-sectional analytic study design, the proportions of non-frail, pre-frail, and frail persons by the respective presence of 0, 1-2, and ≥ 3 of 5 established frailty criteria: unintentional weight loss, exhaustion, physical-inactivity, weak-grip and slow-walk. We evaluated associations with pre-frailty/frailty using multivariate analysis. RESULTS Of 322 participants assessed (79% men, 58% white non-Hispanic, median age 47 years, 95% on combination antiretroviral therapy [cART], median CD4 + cell count 641 cells/mm3 and 93% HIV RNA < 400 copies/mL), 57% were non-frail, 38% pre-frail, and 5% frail. Age increased from non-frailty through frailty. Notably, however, half of pre-frail and frail participants were < 50 years, and of those, 42% and 100%, respectively, were long-term unemployed (versus 16% of non-frail counterparts). In multivariate analysis, pre-frail/frail participants were more likely to have Hepatitis C seropositivity (adjusted odds ratio [aOR] 3.24, 95% CI: 1.35-7.78), a history of AIDS-defining-illness (aOR 3.51, 95% CI: 1.82-6.76), greater depressive symptoms (aOR 1.16, 95% CI:1.09-1.23), higher D-dimer levels (aOR 2.94, 95% CI:1.10-7.87), and were less likely to be white non-Hispanic (aOR 0.35, 95% CI: 0.20-0.61). CONCLUSIONS Pre-frailty and frailty are prevalent in the cART era and are associated with unemployment even among persons < 50 years. Pre-frailty appears to be an intermediate state in the spectrum from non-frailty through frailty and our characterization of pre-frailty/frailty suggests complex multifactorial associations.

Abstract
Habitability is a widely used word in the geoscience, planetary science, and astrobiology literature, but what does it mean? In this review on habitability, we define it as the ability of an environment to support the activity of at least one known organism. We adopt a binary definition of "habitability" and a "habitable environment." An environment either can or cannot sustain a given organism. However, environments such as entire planets might be capable of supporting more or less species diversity or biomass compared with that of Earth. A clarity in understanding habitability can be obtained by defining instantaneous habitability as the conditions at any given time in a given environment required to sustain the activity of at least one known organism, and continuous planetary habitability as the capacity of a planetary body to sustain habitable conditions on some areas of its surface or within its interior over geological timescales. We also distinguish between surface liquid water worlds (such as Earth) that can sustain liquid water on their surfaces and interior liquid water worlds, such as icy moons and terrestrial-type rocky planets with liquid water only in their interiors. This distinction is important since, while the former can potentially sustain habitable conditions for oxygenic photosynthesis that leads to the rise of atmospheric oxygen and potentially complex multicellularity and intelligence over geological timescales, the latter are unlikely to. Habitable environments do not need to contain life. Although the decoupling of habitability and the presence of life may be rare on Earth, it may be important for understanding the habitability of other planetary bodies.

Abstract
Project HEART, an acronym for Helping Enhance Adherence to Retroviral Therapy, was a prospective, controlled study to develop, implement, and evaluate a clinic-based behavioural intervention to prevent adherence failure among HIV-infected adults beginning their first highly active antiretroviral therapy (HAART) regimen (N = 227). In this paper, we describe the conceptualisation of the Project HEART adherence intervention, characteristics of the participants, and lessons learned implementing HEART in an inner-city clinic setting. A multi-component intervention, HEART combined enhanced education, reminders, adherence feedback, social support and adherence-focused problem solving in an integrated manner to address common cognitive, motivational, and social barriers to adherence. Unique components of the intervention included use of participant-identified adherence support partners and a standardized adherence barriers assessment to develop and implement individualised adherence plans. Lessons learned regarding the feasibility of using participant-identified support partners were as follows. Few participants eligible for the study had trouble identifying a support partner. Over 90% of support partners attended at least one intervention visit. Support partners were most available and amenable to participate early in the initiation of therapy. Participants' experiences as the 'supported' partner were generally positive. Though many participants faced barriers not easily addressed by this intervention (for example, housing instability), formally integrating support partners into the intervention helped to address many other common adherence barriers. Family and friends are an under-utilised resource in HIV medication adherence. Enlisting the help of support partners is a practical and economical approach to adherence counselling.

Abstract
BACKGROUND A randomized trial of a primary care-based intervention to prevent depression relapse resulted in improved adherence to long-term antidepressant medication and depression outcomes. We evaluated the effects of this intervention on behavioural processes and identified process predictors of improved depressive symptoms. METHOD Patients at high risk for depression recurrence or relapse following successful acute phase treatment (N=386) were randomly assigned to receive a low intensity 12-month intervention or continued usual care. The intervention combined education about depression, shared decision-making regarding use of maintenance pharmacotherapy and cognitive-behavioural strategies to promote self-management. Baseline, 3, 6, 9 and 12-month interviews assessed patients' self-care practices, self-efficacy for managing depression and depressive symptoms. RESULTS Intervention patients had significantly greater self-efficacy for managing depression (P<0.01) and were more likely to keep track of depressive symptoms (P<0.0001), monitor early warning signs (P<0.0001), and plan for coping with high risk situations (P<0.0001) at all time points compared to usual care control patients. Self-efficacy for managing depression (P<0.0001), keeping track of depressive symptoms (P=0.05), monitoring for early warning signs (P=0.01), engaging in pleasant activities (P<0.0001) and engaging in social activities (P<0.0001) positively predicted improvements in depression symptom scores. CONCLUSIONS A brief intervention designed to target cognitive-behavioural factors and promote adherence to pharmacotherapy in order to prevent depression relapse was highly successful in changing several behaviours related to controlling depression. Improvements in self-efficacy and several self-management behaviours that were targets of the intervention were significantly related to improvements in depression outcome.

Abstract
Adults with attention deficit hyperactivity disorder (ADHD; n = 104) were compared with a control group (n = 64) on time estimation and reproduction tasks. Results were unaffected by ADHD subtype or gender. The ADHD group provided larger time estimations than the control group, particularly at long intervals. This became nonsignificant after controlling for IQ. The ADHD group made shorter reproductions than did the control group (15- and 60-s intervals) and greater reproduction errors (12-, 45-, 60-s durations). These differences remained after controlling for IQ and comorbid oppositional defiant disorder, depression, and anxiety. Only the level of anxiety contributed to errors (at 12-s duration) beyond the level of ADHD. Results extended findings on time perception in ADHD children to adults and ruled out comorbidity as the basis of the errors.

Abstract
OBJECTIVE The authors evaluated the incremental cost-effectiveness of stepped collaborative care for patients with persistent depressive symptoms after usual primary care management. METHOD Primary care patients initiating antidepressant treatment completed a standardized telephone assessment 6-8 weeks after the initial prescription. Those with persistent major depression or significant subthreshold depressive symptoms were randomly assigned to continued usual care or collaborative care. The collaborative care included systematic patient education, an initial visit with a consulting psychiatrist, 2-4 months of shared care by the psychiatrist and primary care physician, and monitoring of follow-up visits and adherence to medication regimen. Clinical outcomes were assessed through blinded telephone assessments at 1, 3, and 6 months. Health services utilization and costs were assessed through health plan claims and accounting data. RESULTS Patients receiving collaborative care experienced a mean of 16.7 additional depression-free days over 6 months. The mean incremental cost of depression treatment in this program was $357. The additional cost was attributable to greater expenditures for antidepressant prescriptions and outpatient visits. No offsetting decrease in use of other health services was observed. The incremental cost-effectiveness was $21.44 per depression-free day. CONCLUSIONS A stepped collaborative care program for depressed primary care patients led to substantial increases in treatment effectiveness and moderate increases in costs. These findings are consistent with those of other randomized trials. Improving outcomes of depression treatment in primary care requires investment of additional resources, but the return on this investment is comparable to that of many other widely accepted medical interventions.

Abstract
OBJECTIVE To determine the effects of lower doses of conjugated equine estrogens (CEE) alone or CEE and medroxyprogesterone acetate (MPA) on lipoproteins, carbohydrate metabolism, and coagulation/fibrinolytic factors. DESIGN Randomized, double-blind, placebo-controlled study. SETTING Multicenter substudy of the Women's HOPE trial. PATIENT(S) Seven hundred and forty-nine healthy, postmenopausal women. INTERVENTION(S) Women were randomized to receive the following doses in milligrams per day: 0.625 CEE; 0.625 CEE/2.5 MPA; 0.45 CEE; 0.45 CEE/2.5 MPA; 0.45 CEE/1.5 MPA; 0.3 CEE; 0.3 CEE/1.5 MPA; or placebo. MAIN OUTCOME MEASURE(S) Assessment of lipids, lipoproteins, glucose tolerance, and coagulation/fibrinolytic factors at baseline, cycle 6, and year 1. RESULT(S) One year of treatment with any of the CEE or CEE/MPA regimens studied increased high-density lipoprotein cholesterol (HDL-C); the 10% increase in HDL-C for the CEE 0.45/MPA 1.5 group was similar to the CEE 0.625/MPA 2.5 group. Low-density lipoprotein cholesterol was significantly reduced in all of the active treatment groups except the CEE 0.3/MPA 1.5 group at cycle 13. Apolipoprotein A-I and triglyceride levels increased and apolipoprotein B levels decreased in all groups. The lipoprotein (a) level was reduced in the CEE 0.45/MPA 2.5, CEE 0.45/MPA 1.5, and CEE 0.625/MPA 2.5 groups. Minimal changes were observed in carbohydrate metabolism for all groups. Fibrinogen and PAI-1 activity decreased and plasminogen activity increased in all groups. Decreases in antithrombin III and protein S activities were significant for all active treatment groups except the CEE 0.3/MPA 1.5 group. CONCLUSION(S) Lower doses of CEE and CEE/MPA induce favorable changes in lipids, lipoproteins, and hemostatic factors with minimal changes in carbohydrate metabolism.

Abstract
Young adults with attention deficit-hyperactivity disorder (ADHD; N = 105) were compared with a control group (N = 64) on 14 measures of executive function and olfactory identification using a 2 (group) X 2 (sex) design. The ADHD group performed significantly worse on 11 measures. No Group X Sex interaction was found on any measures. No differences were found in the ADHD group as a function of ADHD subtype or comorbid oppositional defiant disorder. Comorbid depression influenced the results of only 1 test (Digit Symbol). After IQ was controlled for, some group differences in verbal working memory, attention, and odor identification were no longer significant, whereas those in inhibition, interference control, nonverbal working memory, and other facets of attention remained so. Executive function deficits found in childhood ADHD exist in young adults with ADHD and are largely not influenced by comorbidity but may be partly a function of low intelligence.

Abstract
OBJECTIVE This article describes the conceptual underpinnings, implementation, and participation rates of a twelve-month low-intensity primary care-based intervention to prevent depression relapse. The intervention was designed to address the inherent problems in delivery of effective maintenance treatment in a population based sample of primary care patients. METHODS Patients at high risk of relapse based on psychiatric history who recovered from depression six to eight weeks after initiation of pharmacotherapy by their primary care physician were eligible; 194 were randomized to receive the intervention. The intervention combined education about depression, motivation-enhancing shared decision-making regarding the use of maintenance pharmacotherapy, and cognitive-behavioral strategies. The program included two visits with a Depression Prevention Specialist working in tandem with the primary care physician at the primary care clinic, with supervision and back up from a consulting psychiatrist, proactive follow-up telephone calls and mailed personalized feedback. RESULTS Ninety-three percent of patients attended both in-person visits; 97 percent attended one visit. Eighty percent of patients completed all three follow-up telephone calls, and 85 percent returned at least one mailed feedback form; 48 percent returned all four forms. Offered a menu of options for self-management, most patients chose medication as well as a variety of behavioral strategies. At six months, 72 percent ofpatients and at twelve months 62 percent of patients remained on antidepressant medication. CONCLUSIONS We conclude that it is feasible to integrate a low intensity, twelve-month relapse prevention intervention for depression into a primary care clinic.

Abstract
Science is the process of discovering truth, and "truth" is sampled each time we do a study. The results from all of our studies will be distributed around the truth, and different study designs give different amounts and different qualities of sampled material. Truth is ascertained only when sufficient numbers of appropriate studies are conducted, and no one study or one study design has a monopoly on truth. Currently, the randomized clinical trial is considered the penultimate study design and the ultimate test of the hypothesis, but only if it is double-blinded, placebo-controlled, and analyzed by an intention-to-treat protocol. The study design most similar to the randomized controlled trial is the prospective cohort study. In this observational approach, a cohort (group of individuals) is assembled and followed in real time while end points (e.g. breast cancers, heart attacks, fractures) accrue. This is contrasted to the randomized controlled trial, where a group of individuals is assembled, intervened upon, and followed in real time while end points accrue. The major advantage of the randomized controlled trial over an observational study is that the randomization process should eliminate any "bias" in the exposure of interest. However, the randomized controlled trial, like all study designs, has other limitations. Major limitations of the randomized controlled trial include significant financial and other costs, problems with external generalizability, the placebo effect, external monitoring, multi-center differences, and the (frequently problematic) intention-to-treat analysis rule. Many of these limitations do not occur in prospective cohort studies. For example, since a placebo is not administered in an observational study, there is no placebo effect, and since the study is not monitored by a data and safety monitoring board, abrupt truncation of the study duration is not usually seen in observational cohort studies. These limitations of randomized controlled trials are discussed, with specific references to several recently published randomized controlled trials in women (HERS, NSABP P-1, and the Royal Marsden Hospital trials). The HERS trial is significant because despite overwhelming observational evidence that menopausal estrogen therapy prevents heart disease, HERS found no overall difference in heart disease events in women assigned to an estrogen-plus-progestin intervention. The NSABP P-1 and the Royal Marsden Hospital trials are significant in that they were testing the same hypothesis (whether tamoxifen can prevent breast cancer), but came to entirely different conclusions. Two major questions will be posed from this specific review: One: Given conflicting evidence by study design (observational vs. randomized clinical trial), does menopausal estrogen therapy protect against heart disease? Two: Given conflicting evidence within study design (conflicting randomized clinical trials), does tamoxifen prevent breast cancer?

Abstract
BACKGROUND Despite high rates of relapse and recurrence, few primary care patients with recurrent or chronic depression are receiving continuation and maintenance-phase treatment. We hypothesized that a relapse prevention intervention would improve adherence to antidepressant medication and improve depression outcomes in high-risk patients compared with usual primary care. METHODS Three hundred eighty-six patients with recurrent major depression or dysthymia who had largely recovered after 8 weeks of antidepressant treatment by their primary care physicians were randomized to a relapse prevention program (n = 194) or usual primary care (n = 192). Patients in the intervention group received 2 primary care visits with a depression specialist and 3 telephone visits over a 1-year period aimed at enhancing adherence to antidepressant medication, recognition of prodromal symptoms, monitoring of symptoms, and development of a written relapse prevention plan. Follow-up assessments were completed at 3, 6, 9, and 12 months by a telephone survey team blinded to randomization status. RESULTS Those in the intervention group had significantly greater adherence to adequate dosage of antidepressant medication for 90 days or more within the first and second 6-month periods and were significantly more likely to refill medication prescriptions during the 12-month follow-up compared with usual care controls. Intervention patients had significantly fewer depressive symptoms, but not fewer episodes of relapse/recurrence over the 12-month follow-up period. CONCLUSIONS A relapse prevention program targeted to primary care patients with a high risk of relapse/recurrence who had largely recovered after antidepressant treatment significantly improved antidepressant adherence and depressive symptom outcomes.

Abstract
OBJECTIVE Previous treatment trials have found that approximately one third of depressed patients have persistent symptoms. We examined whether depression severity, comorbid psychiatric illness, and personality factors might play a role in this lack of response. DESIGN Randomized trial of a stepped collaborative care intervention versus usual care. SETTING HMO in Seattle, Wash. PATIENTS Patients with major depression were stratified into severe (N = 149) and mild to moderate depression (N = 79) groups prior to randomization. INTERVENTIONS A multifaceted intervention targeting patient, physician, and process of care, using collaborative management by a psychiatrist and primary care physician. MEASUREMENTS AND MAIN RESULTS Patients with more severe depression had a higher risk for panic disorder (odds ratio [OR], 5.8), loneliness (OR, 2.6), and childhood emotional abuse (OR, 2.1). Among those with less severe depression, intervention patients showed significantly improved depression outcomes over time compared with those in usual care (z = -3.06, P<.002); however, this difference was not present in the more severely depressed groups (z = 0.61, NS). Although the group with severe depression showed differences between the intervention and control groups from baseline to 3 months that were similar to the group with less severe depression (during the acute phase of the intervention), these differences disappeared by 6 months. CONCLUSIONS Initial depression severity, comorbid panic disorder, and other psychosocial vulnerabilities were associated with a decreased response to the collaborative care intervention. Although the intervention was appropriate for patients with moderate depression, individuals with higher levels of depression may require a longer continuation phase of therapy in order to achieve optimal depression outcomes.

Abstract
OBJECTIVE To assess effects of stepped collaborative care depression intervention on disability. DESIGN Randomized controlled trial. SETTING Four primary care clinics of a large health maintenance organization. PATIENTS Two hundred twenty-eight patients with either 4 or more persistent major depressive symptoms or a score of 1.5 or greater on the Hopkins Symptom Checklist. Depression items were randomized to stepped care intervention or usual care 6 to 8 weeks after initiating antidepressant medication. INTERVENTION Augmented treatment of persistently depressed patients by an on-site psychiatrist collaborating with primary care physicians. Treatment included patient education, adjustment of pharmacotherapy, and proactive monitoring of outcomes. MAIN OUTCOME MEASURES Baseline, 1-, 3-, and 6-month assessments of the Sheehan Disability Scale and the social function and role limitation subscales of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). RESULTS Patients who received the depression intervention experienced less interference in their family, work, and social activities than patients receiving usual primary care (Sheehan Disability Scale, z = 2.23; P =.025). Patients receiving intervention also reported a trend toward more improvement in SF-36-defined social functioning than patients receiving usual care (z = 1.63, P =.10), but there was no significant difference in role performance (z = 0.07, P =.94). CONCLUSIONS Significant disability accompanied depression in this persistently depressed group. The stepped care intervention resulted in small to moderate functional improvements for these primary care patients. Arch Fam Med. 2000;9:1052-1058

Abstract
OBJECTIVE The objective of this work was to determine whether there are detectable differences among primary care physicians in measures of quality of care or clinical outcome for depressed patients during the first 2 months of treatment with antidepressant medication. METHODS We studied 1,599 depressed primary care patients initiating antidepressant treatment from 63 family physicians in 4 primary care clinics of a staff-model health maintenance organization. Patients were interviewed 6 to 8 weeks after initiating antidepressant medication with a telephone structured interview that included the Structural Clinical Interview for DSM-IV Diagnoses (SCID). Automated databases of the HMO were used to examine 3 quality-of-care measures: (1) the percentage of patients who had a refill of their antidepressant by 6 weeks, (2) the percentage of patients who had a return visit by 3 weeks, and (3) the percentage of patients having a return visit by 6 weeks. The percentage of patients in each primary care physician panel who had > or =4 persistent DSM-IV depressive symptoms at 6 to 8 weeks was the main clinical outcome variable. To adjust for case-mix differences between physician panels, patient age, gender, and medical comorbidity were controlled for in the analyses. Two covariates were used to adjust for differences in patients' clinical severity: self-report of > or =2 prior depressive episodes and an SCID diagnosis of major depression during the patient's worst episode in the last 2 years. Physician age, gender, and part-time versus full-time practice were also used as covariates. RESULTS The wide observed range of variability in quality-of-care and clinical outcome measures by physician practice decreased markedly in the statistical model that controlled for patient-level covariates and differences in the number of patients seen per provider. We did not detect differences in physician practice for the percentage of patients who had a return visit by 3 or 6 weeks, the percentage of patients who had a refill of their antidepressant prescription by 6 weeks, or the percentage of patients with an adverse clinical outcome of depression. CONCLUSIONS We did not find important differences in measures of quality of care or patient outcomes by physician. These results may have implications for the use of physician profiling and other forms of physician report cards.

Abstract
BACKGROUND Despite improvements in the accuracy of diagnosing depression and use of medications with fewer side effects, many patients treated with antidepressant medications by primary care physicians have persistent symptoms. METHODS A group of 228 patients recognized as depressed by their primary care physicians and given antidepressant medication who had either 4 or more persistent major depressive symptoms or a score of 1.5 or more on the Hopkins Symptom Checklist depression items at 6 to 8 weeks were randomized to a collaborative care intervention (n = 114) or usual care (n = 114) by the primary care physician. Patients in the intervention group received enhanced education and increased frequency of visits by a psychiatrist working with the primary care physician to improve pharmacologic treatment. Follow-up assessments were completed at 1, 3, and 6 months by a telephone survey team blinded to randomization status. RESULTS Those in the intervention group had significantly greater adherence to adequate dosage of medication for 90 days or more and were more likely to rate the quality of care they received for depression as good to excellent compared with usual care controls. Intervention patients showed a significantly greater decrease compared with usual care controls in severity of depressive symptoms over time and were more likely to have fully recovered at 3 and 6 months. CONCLUSIONS A multifaceted program targeted to patients whose depressive symptoms persisted 6 to 8 weeks after initiation of antidepressant medication by their primary care physician was found to significantly improve adherence to antidepressants, satisfaction with care, and depressive outcomes compared with usual care.

Abstract
The authors examined automated pharmacy and visit data for 502 members of a large-staff model health maintenance organization (HMO) who had been diagnosed with depression and started on antidepressants by their primary-care providers. Older patients (age >/=60; n=110) were less likely than younger adults (age 18-59, n=110) to receive adequate doses of antidepressant medications for 30 or 90 days. Older adults were also less likely than younger adults to receive more than two primary-care visits for depression in the 12 weeks after receiving a new antidepressant prescription and were less likely to receive specialty mental health care in the 6 months after receiving a new antidepressant prescription.

Abstract
BACKGROUND In longitudinal studies, greater mammographic density is associated with an increased risk for breast cancer. OBJECTIVE To assess differences between placebo, estrogen, and three estrogen-progestin regimens on change in mammographic density. DESIGN Subset analysis of a 3-year, multicenter, double-blind, randomized, placebo-controlled trial. SETTING Seven ambulatory study centers. PARTICIPANTS 307 of the 875 women in the Postmenopausal Estrogen/Progestin Interventions Trial. Participants had a baseline mammogram and at least one follow-up mammogram available, adhered to treatment, had not taken estrogen for at least 5 years before baseline, and did not have breast implants. INTERVENTION Treatments were placebo, conjugated equine estrogens (CEE), CEE plus cyclic medroxyprogesterone acetate (MPA), CEE plus daily MPA, and CEE plus cyclic micronized progesterone (MP). MEASUREMENTS Change in radiographic density (according to American College of Radiology Breast Imaging Reporting and Data System grades) on mammography. RESULTS Almost all increases in mammographic density occurred within the first year. At 12 months, the percentage of women with density grade increases was 0% (95% CI, 0.0% to 4.6%) in the placebo group, 3.5% (CI, 1.0% to 12.0%) in the CEE group, 23.5% (CI, 11.9% to 35.1%) in the CEE plus cyclic MPA group, 19.4% (CI, 9.9% to 28.9%) in the CEE plus daily MPA group, and 16.4% (CI, 6.6% to 26.2%) in the CEE plus cyclic MP group. At 12 months, the odds of an increase in mammographic density were 13.1 (95% CI, 2.4 to 73.3) with CEE plus cyclic MPA, 9.0 (CI, 1.6 to 50.1) with CEE plus daily MPA, and 7.2 (CI, 1.3 to 40.0) with CEE plus cyclic micronized progesterone compared with CEE alone. CONCLUSIONS Further study of the magnitude and meaning of increased mammographic density due to use of estrogen and estrogen-progestins is warranted because mammographic density may be a marker for risk for breast cancer.

Abstract
This paper examines the development of a teaching format suitable for teaching spirituality and spiritual care to a group of mature age nurses, all of whom are older than the age of 25 years. A teacher's journal was kept that assisted in the identification of classroom activities, which aided in relating these experiences to concepts and practices of adult learning. These principles of learning included the use of the students' preparedness to learn, respect for the student as a learner and the use of the group processes to facilitate the exchanges of experiences and learning between the educator and the students. Whilst these precepts were valuable as a means of resolving teaching concerns, it was the journal entries that identified the issues relating to the teaching process. Some of these issues were the use of student and educator experiences as a medium for reflection, the willingness of the educator to follow students' wishes to discuss apparently unrelated material, the facilitator will be apart from the group as well as part of the group, and the necessity for journal entries to be made as soon as possible after the completion of the class.

Abstract
This article compares self-report and automated data as measures of dose and duration of antidepressant use in order to assess the feasibility of using automated pharmacy data in a disease management context. We used self-report and computerized refill data to identify two treatment failures-premature discontinuation of the medication and sub-optimal dosages-at time points 1 and 4 months after initiation of antidepressant therapy. The sources showed modest agreement regarding identification of current users at 1 month (kappa = .33); agreement was high at 4 months (kappa = .72). Agreement regarding dosage adequacy was also higher later in treatment, with kappas of .52 and .65 at 1 and 4 months, respectively. The two sources showed high agreement on an overall measure of acute phase treatment adequacy (kappa = .80). Data completeness was another outcome, with data on current users and overall treatment adequacy generally available from computerized files, data on dose less so. Automated pharmacy data appear to be a feasible means of monitoring treatment adequacy and quality of care as part of a disease management approach to improving care for populations of patients.

Abstract
CONTEXT Observational studies have found lower rates of coronary heart disease (CHD) in postmenopausal women who take estrogen than in women who do not, but this potential benefit has not been confirmed in clinical trials. OBJECTIVE To determine if estrogen plus progestin therapy alters the risk for CHD events in postmenopausal women with established coronary disease. DESIGN Randomized, blinded, placebo-controlled secondary prevention trial. SETTING Outpatient and community settings at 20 US clinical centers. PARTICIPANTS A total of 2763 women with coronary disease, younger than 80 years, and postmenopausal with an intact uterus. Mean age was 66.7 years. INTERVENTION Either 0.625 mg of conjugated equine estrogens plus 2.5 mg of medroxyprogesterone acetate in 1 tablet daily (n = 1380) or a placebo of identical appearance (n = 1383). Follow-up averaged 4.1 years; 82% of those assigned to hormone treatment were taking it at the end of 1 year, and 75% at the end of 3 years. MAIN OUTCOME MEASURES The primary outcome was the occurrence of nonfatal myocardial infarction (MI) or CHD death. Secondary cardiovascular outcomes included coronary revascularization, unstable angina, congestive heart failure, resuscitated cardiac arrest, stroke or transient ischemic attack, and peripheral arterial disease. All-cause mortality was also considered. RESULTS Overall, there were no significant differences between groups in the primary outcome or in any of the secondary cardiovascular outcomes: 172 women in the hormone group and 176 women in the placebo group had MI or CHD death (relative hazard [RH], 0.99; 95% confidence interval [CI], 0.80-1.22). The lack of an overall effect occurred despite a net 11% lower low-density lipoprotein cholesterol level and 10% higher high-density lipoprotein cholesterol level in the hormone group compared with the placebo group (each P<.001). Within the overall null effect, there was a statistically significant time trend, with more CHD events in the hormone group than in the placebo group in year 1 and fewer in years 4 and 5. More women in the hormone group than in the placebo group experienced venous thromboembolic events (34 vs 12; RH, 2.89; 95% CI, 1.50-5.58) and gallbladder disease (84 vs 62; RH, 1.38; 95% CI, 1.00-1.92). There were no significant differences in several other end points for which power was limited, including fracture, cancer, and total mortality (131 vs 123 deaths; RH, 1.08; 95% CI, 0.84-1.38). CONCLUSIONS During an average follow-up of 4.1 years, treatment with oral conjugated equine estrogen plus medroxyprogesterone acetate did not reduce the overall rate of CHD events in postmenopausal women with established coronary disease. The treatment did increase the rate of thromboembolic events and gallbladder disease. Based on the finding of no overall cardiovascular benefit and a pattern of early increase in risk of CHD events, we do not recommend starting this treatment for the purpose of secondary prevention of CHD. However, given the favorable pattern of CHD events after several years of therapy, it could be appropriate for women already receiving this treatment to continue.

Abstract
The Heart and Estrogen/progestin Replacement Study (HERS) is a randomized, double-blind, placebo-controlled trial designed to test the efficacy and safety of estrogen plus progestin therapy for prevention of recurrent coronary heart disease (CHD) events in women. The participants are postmenopausal women with a uterus and with CHD as evidenced by prior myocardial infarction, coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, or other mechanical revascularization or at least 50% occlusion of a major coronary artery. Between February 1993 and September 1994, 20 HERS centers recruited and randomized 2763 women. Participants ranged in age from 44 to 79 years, with a mean age of 66.7 (SD 6.7) years. Most participants were white (89%), married (57%), and had completed high school or some college (80%). As expected, the prevalence of coronary risk factors was high: 62% were past or current smokers, 59% had hypertension, 90% had serum LDL-cholesterol of 100 mg/dL or higher, and 23% had diabetes. Each woman was randomly assigned to receive one tablet containing 0.625 mg conjugated estrogens plus 2.5 mg medroxyprogesterone acetate daily or an identical placebo. Participants will be evaluated every 4 months for an average of 4.2 years for the occurrence of CHD events (CHD death and nonfatal myocardial infarction). We will also assess other major CHD endpoints, including revascularization and hospitalization for unstable angina. The primary analysis will compare the rate of CHD events in women assigned to active treatment with the rate in those assigned to placebo. The trial was designed to have power greater than 90% to detect a 35% reduction in the incidence of CHD events, assuming a 50% lag in effect for 2 years and a 5% annual event rate in the placebo group. The design, analysis, and conduct of the study are controlled by the Steering Committee of Principal Investigators and coordinated at the University of California, San Francisco. HERS is the largest trial of any intervention to reduce the risk of recurrent CHD events in women with heart disease and is the first controlled trial to seek evidence of the efficacy and safety of postmenopausal hormone therapy to prevent recurrent CHD events.

Abstract
BACKGROUND Few data are available regarding the impact of improved depression treatment on daily functioning and disability. METHODS In two studies of more intensive depression treatment in primary care, patients initiating antidepressant treatment were randomly assigned to either usual care or to a collaborative management programme including patient education, on-site mental health treatment, adjustment of antidepressant medication, behavioural activation and monitoring of medication adherence. Assessments at baseline as well as 4 and 7 months included several measures of impairment, daily functioning and disability: self-rated overall health, number of bodily pains, number of somatization symptoms, changes in work due to health, reduction in leisure activities due to health, number of disability days and number of restricted activity days. RESULTS Average data from the 4- and 7-month assessments in both studies, intervention patients reported fewer somatic symptoms (OR 0.68, 95% CI 0.46, 0.99) and more favourable overall health (OR 0.50, 95% CI 0.28, 0.91). While intervention patients fared better on other measures of functional impairment and disability, none of these differences reached statistical significance. CONCLUSIONS More effective acute-phase depression treatment reduced somatic distress and improved self-rated overall health. The absence of a significant intervention effect on other disability measures may reflect the brief treatment and follow-up period and the influence of other individual and environmental factors on disability.

Abstract
OBJECTIVE The report estimates the treatment costs, cost-offset effects, and cost-effectiveness of Collaborative Care of depressive illness in primary care. STUDY DESIGN Treatment costs, cost-offset effects, and cost-effectiveness were assessed in two randomized, controlled trials. In the first randomized trail (N = 217), consulting psychiatrists provide enhanced management of pharmacotherapy and brief psychoeducational interventions to enhance adherence. In the second randomized trial (N = 153). Collaborative Care was implemented through brief cognitive-behavioral therapy and enhanced patient education. Consulting psychologist provided brief psychotherapy supplemented by educational materials and enhanced pharmacotherapy management. RESULTS Collaborative Care increased the costs of treating depression largely because of the extra visits required to provide the interventions. There was a modest cost offset due to reduced use of specialty mental health services among Collaborative Care patients, but costs of ambulatory medical care services did not differ significantly between the intervention and control groups. Among patients with major depression there was a modest increase in cost-effectiveness. The cost per patient successfully treated was lower for Collaborative Care than for Usual Care patients. For patients with minor depression. Collaborative Care was more costly and not more cost-effective than Usual Care. CONCLUSIONS Collaborative Care increased depression treatment costs and improved the cost-effectiveness of treatment for patients with major depression. A cost offset in specialty mental health costs, but not medical care costs, was observed. Collaborative Care may provide a means of increasing the value of treatment services for major depression.

Abstract
Depressed primary care patients (N = 217) were assessed to determine if certain personality characteristics predict health domains independent of chronic disease, demographics, depression, and psychiatric diagnoses. Eleven health variables were used to create three outcome factor scores: disability (e.g., days missed work); somatization (e.g., medically unexplained symptoms); and subjective pain (severity, interference). Neuroticism explained significant variance in all health outcomes independent of the other predictors. Depression and neuroticism interacted in the disability and pain models. Depression was related to health in neurotic patients, while in the absence of neuroticism, little relation between depression and health was observed. Neuroticism may explain why persons with similar health problems have differing levels of disability, pain, and somatization.

Abstract
BACKGROUND Clinicians, policy makers, and health care administrators are attempting to improve depression outcomes in the primary care setting. Despite positive evidence about the efficacy of self-help materials and psychoeducational interventions, use of educational materials designed for the primary care patient are receiving little attention in present depression initiatives. The present study describes the use and evaluation of three educational materials by depressed primary care patients. METHODS As a part of a randomized control trial, depressed primary care patients were identified by primary care physicians and randomized to a clinical trial exploring a new method of treating depression. Patients assigned to the new method of treatment received a package of educational materials at the time of the baseline interview. These materials included two brief interactive booklets (medication booklet, behavioral health booklet) and a short video. The present analysis concerns data obtained from 108 intervention patients in a telephone survey conducted 1 week after they received the package of educational materials. RESULTS Approximately three quarters of the subjects reported that they read or viewed all of the educational products. The majority rated the products as somewhat to significantly helpful: medication booklet 81%; behavioral health booklet 82%; and video 69%. Previously reported results include findings of significantly better medication adherence and improved clinical outcomes by patients with major depression who received a primary care intervention that included the educational products discussed in this paper. CONCLUSIONS Educational materials may play a significant role in improving depression treatment outcomes in the primary care setting.

Abstract
This paper reviews the concepts of population-based care and disease management of major depression. Population-based care and disease management strategies motivated by health care reform provide approaches for organizing health services to lower the prevalence of common medical and psychiatric illnesses in primary care populations. We apply these concepts to the organization of services for patients with major depression.

Abstract
Two models that integrate the psychiatrist into treatment of depression in primary care have been evaluated in randomized controlled trials. In the psychiatrist/primary care model, a psychiatrist alternated visits with a primary care physician to assist in the education and pharmacologic treatment of the patient. In the psychiatrist/psychologist team model, the psychiatrist worked with a team of psychologists to improve adherence to and effectiveness of antidepressant treatment, with psychologists also providing brief behavioral treatment in the primary care clinic. Findings with the psychiatry/primary care model are reported. It was found that the collaborative model was associated with improved adherence to treatment, increased patient satisfaction with depression care, and improved depression outcome compared with usual care by primary care physicians alone. Similar results were found in the study of the psychiatrist/psychologist collaborative care model. The success of these models indicates the appropriateness of a novel role for the psychiatrist and psychologist, i.e., that of collaboration with primary care physicians in care of the depressed patient in the primary care setting.

Abstract
BACKGROUND This research study evaluates the effectiveness of a multifaceted intervention program to improve the management of depression in primary care. METHODS One hundred fifty-three primary care patients with current depression were entered into a randomized controlled trial. Intervention patients received a structured depression treatment program in the primary care setting that included both behavioral treatment to increase use of adaptive coping strategies and counseling to improve medication adherence. Control patients received "usual" care by their primary care physicians. Outcome measures included adherence to antidepressant medication, satisfaction with care of depression and with antidepressant treatment, and reduction of depressive symptoms over time. RESULTS At 4-month follow-up, significantly more intervention patients with major and minor depression than usual care patients adhered to antidepressant medication and rated the quality of care they received for depression as good to excellent. Intervention patients with major depression demonstrated a significantly greater decrease in depression severity over time compared with usual care patients on all 4 outcome analyses. Intervention patients with minor depression were found to have a significant decrease over time in depression severity on only 1 of 4 study outcome analyses compared with usual care patients. CONCLUSION A multifaceted primary care intervention improved adherence to antidepressant regimens and satisfaction with care in patients with major and minor depression. The intervention consistently resulted in more favorable depression outcomes among patients with major depression, while outcome effects were ambiguous among patients with minor depression.

Abstract
OBJECTIVE Little is known about the covariates of hyperglycemia and hyperinsulinemia. We examined candidate factors in postmenopausal women. RESEARCH DESIGN AND METHODS We determined the cross-sectional associations of sociodemographic, body-size, lifestyle, reproductive, and menopausal factors with pretrial fasting and postchallenge glucose and insulin levels in 869 postmenopausal women aged 45-65 years. Women were participants in the Postmenopausal Estrogen/Progestin Interventions study who were not taking estrogen or insulin. RESULTS Plasma glucose levels increased significantly with age; serum insulin levels did not. BMI and waist-to-hip ratio (WHR) each showed graded positive and independent associations with glucose and insulin levels. Alcohol intake, cigarette smoking, physical activity, parity, education, and income were also associated with insulin or glucose in age-adjusted models. In multivariable models, BMI and WHR explained 18% of the variability in fasting glucose, 16% in postchallenge glucose, 28% in fasting insulin, and 17% in postchallenge insulin. Age and all other factors combined accounted for < 6% of the variance in glucose or insulin. In multiply adjusted models, African-American and Hispanic women had higher fasting and 2-h insulin levels than non-Hispanic white women. CONCLUSIONS Most of the variance in glycemia and insulin is unexplained. Measures of obesity and fat distribution account for nearly all the explained variance.

Abstract
OBJECTIVE To compare all-cause and specific-cause mortality rates in women who had or had not used long-term postmenopausal estrogen replacement therapy (ERT). METHODS We identified women who used long-term postmenopausal ERT and compared them with a sample of age-matched postmenopausal nonusers. Through linking of these subjects' medical record numbers to various data bases, we examined survivorship and cause of death among estrogen users and nonusers. The risk of death in 232 postmenopausal women who began ERT within 3 years of menopause and used it for at least 5 years was compared with that of 222 age-matched postmenopausal nonusers. In the users, the mean length of estrogen use was 17.1 years. RESULTS Statistically significant reductions in all-cause mortality were found in users compared with nonusers. For death from any cause, the age-adjusted relative risk (RR) and associated 95% confidence interval (CI) in estrogen users was 0.54 (0.38-0.76). The reduction in all-cause mortality was largely due to reductions in coronary heart disease (RR 0.40, CI 0.16-1.02) and other cardiovascular disease (RR 0.27, CI 0.10-0.71). Overall cancer mortality was similar in the two groups (RR 0.85, CI 0.46-1.58), although estrogen users had a higher risk of death from breast cancer (RR 1.89, CI 0.43-8.36) and lower risk of death from lung cancer (RR 0.22, CI 0.04-1.15). CONCLUSION Long-term ERT use is associated with lower all-cause mortality and confers this apparent protection primarily through reduction in cardiovascular disease.

Abstract
OBJECTIVE To examine outcomes of primary care patients receiving low levels of antidepressant treatment. DESIGN Cohort study comparing patients receiving anti-depressant treatment within and below the recommended dosing range. SETTING Primary care clinics of a staff-model health maintenance organization. PATIENTS Primary care patients initiating antidepressant treatment for depression. MEASUREMENTS AND MAIN RESULTS Of 88 patients beginning antidepressant treatment, 49 (56%) used "adequate" doses for 30 days or more. Likelihood of "adequate" pharmacotherapy was not related to patient age, gender, medical comorbidity, or baseline depression severity. All the patients showed substantial clinical improvement after four months. Compared with those using "adequate" pharmacotherapy, the patients receiving low-intensity treatment had lower likelihood of clinical response (64% vs 84%; chi-square = 4.44; df = 1; p = 0.035). At four months, however, those receiving low-intensity and those receiving higher-intensity treatment did not differ significantly in either the score on the 20-item Symptom Checklist depression scale (18.91 and 15.72, respectively; F = 1.45; df = 1.86; p = 0.23) or the proportion with persistence of major depression (10% and 4%, respectively; chi-square = 1.30; df = 1; p = 0.25). A replication sample of 157 patients (assessed only at baseline and four months) yielded similar results. CONCLUSIONS While the patients receiving recommended levels of pharmacotherapy showed somewhat higher improvement rates, many of the patients receiving "inadequate" treatment experienced good short-term outcomes. Efforts to increase the intensity of depression treatment in primary care should focus on the subgroup of patients who fail to respond to initial treatment.

Abstract
OBJECTIVE To illustrate the use of multivariable optimal discriminant analysis (MultiODA). DESIGN Data from four previously published studies were reanalyzed using MultiODA. The original analysis was Fisher's linear discriminant analysis (FLDA) for two studies and logistic regression analysis (LRA) for two studies. MEASUREMENTS AND MAIN RESULTS In Study 1, FLDA achieved an overall percentage accuracy in classification (PAC) for the training sample of 69.9%, compared with 73.5% for MultiODA. In Study 2, the LRA model required three attributes to achieve a 76.1% overall PAC for the training sample and a 79.4% overall PAC for the hold-out sample. Using only two attributes, the MultiODA model achieved similar values. In Study 3, the FLDA model achieved an overall PAC of 82.5%, compared with 87.5% for the MultiODA model. In Study 4, MultiODA identified a two-attribute model that achieved a 93.3% overall training PAC, when an LRA model could not be developed. CONCLUSIONS MultiODA identified: a superior training model (Study 1); a more parsimonious model that achieved superior overall training and identical hold-out PAC (Study 2); a model that achieved a higher hold-out PAC (Study 3); and a two-attribute model that achieved a relatively high PAC when a multivariable LRA model could not be obtained (Study 4). These findings suggest that MultiODA has the potential to improve the accuracy of predictions made in general internal medicine research.

Abstract
BACKGROUND Although researchers are paying more attention to the treatment of depression in the primary care setting, little is known about the nature of psychotherapeutic interactions that occur between primary care physicians and their patients in the context of a visit for depression. In recent years, brief cognitive behavioral therapy has been demonstrated to be efficacious, and the public has become more familiar with these techniques through media exposure and self-help books. METHODS Depressed primary care patients were surveyed regarding the extent to which cognitive behavioral (CB) techniques were suggested during the primary care visit in which antidepressant medication was initially prescribed. One hundred fifty-five patients completed responses to phone surveys 1 month and 4 months after the visit. Patients were also surveyed regarding the recommendation of counseling by the primary care physician. RESULTS The majority of patients (61%) reported that their physician advised them to identify activities they were already doing that helped them feel better. Physician recommendations regarding planning pleasurable activities, problem solving, challenging depressive thoughts, and planning activities that boost confidence were reported by 22% to 40% of study patients. Older patients reported fewer interactions about CB strategies. Primary care physicians' suggestion of CB strategies was associated with both patient use of CB strategies in the months following the visit and better adherence to recommended medication therapy during the first month of treatment. CONCLUSIONS Many patients seem to recognize the occurrence of psychotherapeutic interactions during visits to their primary care physician in which an antidepressant medication was prescribed, and patients' recognition of these interactions is associated with increased adherence to the recommended course of antidepressant prescriptions.

Abstract
In this study, the authors attempted to determine predictors of adherence to antidepressant therapy and to identify specific educational messages, side effects, and features of doctor-patient collaboration that influence adherence. Patients newly prescribed antidepressants for depression at a health maintenance organization were identified by using automated pharmacy data and medical records review. Patients (n = 155) were interviewed 1 and 4 months after starting antidepressant medication. Approximately 28% of patients stopped taking antidepressants during the first month of therapy, and 44% had stopped taking them by the third month of therapy. Patients who received the following five specific educational messages--1) take the medication daily; 2) antidepressants must be taken for 2 to 4 weeks for a noticeable effect; 3) continue to take medicine even if feeling better; 4) do not stop taking antidepressant without checking with the physician; and 5) specific instructions regarding what to do to resolve questions regarding antidepressants--were more likely to comply during the first month of antidepressant therapy. Asking about prior experience with antidepressants and discussions about scheduling pleasant activities also were related to early adherence. Side effects, only at severe levels, were associated with early noncompliance. Neuroticism, depression severity, and other patient characteristics did not predict adherence. Primary care physicians may be able to enhance adherence to antidepressant therapy by simple and specific educational messages easily integrated into primary care visits.
