Stressful life events, bipolar disorder, and the "kindling model".

A common misconception is that bipolar disorder is an endogenous process. However, previous research suggests a role for life events in the onset of and recovery from bipolar episodes. Yet, there remains some question as to whether the relationship between life events and onset changes over the course of the disorder as a result of the number of episodes an individual has experienced. Using a rigorous interview measure of stressful life events, the current study tested the kindling model (R. M. Post, 1992), which theorizes that major life events play a diminishing role over the course of illness in bipolar patients. Analyses revealed that the number of episodes experienced does not appear to have a significant effect on bipolar 1 patients' reactivity to external stressors. In addition, the results suggest that a more complex relationship exists among age, stress, and onset of new episodes than can be adequately explained by the kindling model.

A comparison of two life stress assessment approaches: prospective prediction of treatment outcome in recurrent depression.

Research on life stress has been characterized by inconsistent results, which some researchers attribute to different assessment methodologies. Generally, studies have used either self-report checklists or investigator-based interviews. To test whether different results are derived from these approaches, the authors compared information from a self-report measure of life stress with the additional data available from a follow-up investigator-based measure in prospectively predicting the outcome of treatment for recurrent major depression. The 2 approaches produced different results, with investigator-based life events predicting lower probability of remission and self-report life events either predicting increased likelihood of remission or not predicting at all. The results demonstrated that methodology may account for some of the inconsistencies in the life stress literature.

U.S. Women Physicians' personal and clinical breast cancer screening practices.

Little is known about predictors of physicians' personal or clinical compliance with breast cancer screening recommendations. We explored this in 4501 respondents to the Women Physicians' Health Study, a questionnaire-based study of a representative sample of U.S. women M. D.s. Overall, 21% of women physicians performed breast self-examination (BSE) at least monthly, about two thirds had received a clinical breast examination (CBE) within the last year, and 85% had received one within the last 2 years. Of those <40 years old, 14% had received a mammogram in the past year, as had 42% of those 40-49 and 59% of those 50-70 years old. Being a primary care practitioners or obstetrician/gynecologist was a significant predictor of counseling or screening for CBE and mammography. Only 46% of all women physicians reported discussing or performing mammograms at least once a year for those >/=50-</=75 years old, and 53% reported doing so for CBE. Also associated with performing CBE was examining one's own breasts at least once a year. Associated with mammography were having had a mammogram oneself in the past year and having a personal history of breast cancer. Other parameters, including age, ethnicity, region, practice type, practice site, control of work environment, work hours, amount of general continuing medical education (CME), career satisfaction, general health status, other breast disorders, personally having a recent CBE, or family histories of breast cancer or any other breast disorder, were not multivariately significantly associated with our counseling frequency outcomes. Women physicians may be especially efficient targets for breast cancer screening education.

Use of vitamin-mineral supplements by female physicians in the United States.

BACKGROUND: Rates of vitamin-mineral supplement use by US female physicians are unknown but are of particular interest for several epidemiologic and clinical reasons. OBJECTIVE: The objective was to determine rates of and variations in vitamin-mineral supplement use among US female physicians. DESIGN: We used data from the Women Physicians' Health Study, a large (n = 4501) national, randomly sampled mail survey of female physicians aged 30-70 y. RESULTS: Half of the physicians took a multivitamin-mineral supplement; 35.5% of these did so regularly. However, </=33% took any supplement other than calcium and <20% did so regularly. Regular vitamin-mineral supplement use increased with age, and antioxidant intake was higher in those at high risk of heart disease. Those with a history of osteoporosis were nearly 3 times as likely as those with no history to take supplemental calcium regularly. Those who took any supplement regularly also consumed more fruit and vegetables daily than did occasional users or nonusers (P: < 0.0001). Regular users of any supplement also consumed less fat than did occasional users or nonusers (P: < 0.01). Additionally, vegetarians were more likely than were nonvegetarians to regularly consume any supplement (59.9% compared with 46.3%; P: < 0.001) and those who regularly consumed any supplement were more likely to comply with US Preventive Services Task Force guidelines than were those who were occasional users or nonusers (72.4% compared with 66.5% and 60.2%; P: < 0.0001). CONCLUSION: Female physicians, particularly those who were especially health conscious or at higher risk of heart disease or osteoporosis, used supplements at rates at least equal to those of women in the general population.

Caring for medical students as patients: access to services and care-seeking practices of 1,027 students at nine medical schools. Collaborative Research Group on Medical Student Healthcare.

PURPOSE: The personal health care of medical students is an important but neglected issue in medical education. Preliminary work suggests that medical student-patients experience special barriers to health care services and report problematic care-seeking practices that merit further inquiry. METHOD: A self-report questionnaire was piloted, revised, and distributed to students at nine medical schools in 1996-97. The survey included questions regarding access to health services, care-seeking practices, and demographic information. RESULTS: A total of 1,027 students participated (52% response rate). Ninety percent reported needing care for various health concerns. Fifty-seven percent did not seek care at times, in part due to training demands, and 48% had encountered difficulties in obtaining care. A majority had received treatment at their training institutions, and students commonly pursued informal or "curbside" care from medical colleagues. Almost all participants (96%) were insured. Differences in responses were associated with level of training, gender, and medical school. CONCLUSION: Medical schools shoulder the responsibility not only of educating but also of providing health services for their students. Students encounter barriers to care and engage in problematic care-seeking practices. Greater attention to issues surrounding medical student health may benefit students and their future patients.

Assessment of life stress in adolescents: self-report versus interview methods.

OBJECTIVE: To compare the investigator-based Life Events and Difficulties Schedule (LEDS) with a self-report measure (Life Events Checklist [LEC]) for the purpose of measuring life stress in adolescents with and without a diagnosis of major depressive disorder (MDD). METHOD: Adolescents (aged 13-18 years) with a recent episode of MDD based on DSM-III-R (n = 35) and normal controls free of any Axis I lifetime psychiatric disorder (n = 35) were assessed using both the LEC and the LEDS. RESULTS: Both measures predicted membership in the depressed and nondepressed groups of adolescents. Adolescents in the depressed group were more likely to report a severe event on the LEDS (97%) than adolescents in the nondepressed group (66%) (p = .001). Similarly, subjects in the depressed group endorsed a greater number of negative events (mean = 8.1) on the LEC than subjects in the nondepressed group (mean = 3.0) (p = .0001). An examination of potential provoking agents for episodes of major depression revealed that the LEC captured only 32% of preonset severe events and 36% of preonset major difficulties identified by the LEDS. CONCLUSIONS: Interpreted in light of relative advantages and disadvantages, the results suggest that checklist and interview measures each have distinct advantages depending on the purpose for which they are being used.

Risk-benefit decision making for treatment of depression during pregnancy.

OBJECTIVE: The Committee on Research on Psychiatric Treatments of the American Psychiatric Association identified treatment of major depression during pregnancy as a priority area for improvement in clinical management. The goal of this article was to assist physicians in optimizing treatment plans for childbearing women. METHOD: The authors' work group developed a decision-making model designed to structure the information delivered to pregnant women in the context of the risk-benefit discussion. Perspectives of forensic and decision-making experts were incorporated. RESULTS: The model directs the psychiatrist to structure the problem through diagnostic formulation and identification of treatment options for depression. Reproductive toxicity in five domains (intrauterine fetal death, physical malformations, growth impairment, behavioral teratogenicity, and neonatal toxicity) is reviewed for the potential somatic treatments. The illness (depression) also is characterized by symptoms of somatic dysregulation that compromise health during pregnancy. The patient actively participates and provides her evaluation of the acceptability of the various treatments and outcomes. Her capacity to participate in this process provides evidence of competence to consent. Included in the decision-making process are the patient's significant others and obstetrical physician. The process is ongoing, with the need for incorporation of additional data as the pregnancy and treatment response progress. CONCLUSIONS: The conceptual model provides structure to a process that is frequently stressful for both patients and psychiatrists. By applying the model, clinicians will ensure that critical aspects of the risk-benefit discussion are included in their care of pregnant women.

Diagnosis of nonpsychotic patients in community clinics.

OBJECTIVE: Diagnosis-specific, proven efficacious treatments are a major recent advance in psychiatry. Appropriate use of such treatments presupposes patients who meet the diagnostic criteria and clinicians who have accurately diagnosed the target disorder and comorbid conditions. Since little is known about whether these prerequisites are commonly met, the authors conducted a study at two community treatment sites to determine the frequency of various axis I diagnoses and the concordance between the diagnoses recorded in patient charts and those obtained by a structured interview. Given that a DSM diagnosis may not be sufficient to understand a patient's problems, the authors also obtained ratings of interpersonal functioning. METHOD: The subjects were 164 nonpsychotic patients who were seen at a rural (N=114) or urban (N=50) community treatment facility. Raters trained to reliably use the Structured Clinical Interview for DSM-IV (SCID) conducted diagnostic interviews. Clinical charts were reviewed to obtain clinical diagnoses. Patients completed questionnaires regarding interpersonal functioning. RESULTS: Most (N=145, 88%) of the patients met the SCID criteria for a current axis I diagnosis, and 53% (N=87) met the criteria for two or more disorders. Clinical and SCID diagnoses had poor agreement. Evidence was found for interpersonal dysfunction. CONCLUSIONS: Most patients met the diagnostic criteria for conditions for which there are proven treatments; however, inaccurate diagnosis proved common. This barrier to optimal treatment could be ameliorated with the use of structured interviews for common diagnoses. Scores on social/interpersonal measures support the premise that DSM symptoms provide only part of the relevant information about patients' conditions.

Anxiety as a correlate of response to the acute treatment of bipolar I disorder.

OBJECTIVE: Given the adverse impact of anxiety on treatment outcome in unipolar depression and the paucity of data on the role of anxiety in bipolar disorder, the authors sought to determine the effect of anxiety on the acute treatment response of patients with bipolar I disorder. METHOD: The authors examined the correlates of response to the acute treatment of 124 consecutively treated patients with bipolar I disorder. Measures of anxiety included history of panic attacks and a composite variable reflecting current or past anxiety symptoms. RESULTS: History of panic attacks proved to be a significant correlate of nonremission. Anxiety, as assessed with the composite variable, was associated with longer time to remission, as was the treatment of depressive versus manic symptoms and mixed versus manic symptoms. Patients with anxiety as assessed with the composite variable and patients with a history of panic attacks reported more severe medication side effects. They also required a greater number of medications, either sequentially or in combination, in order to achieve remission. CONCLUSIONS: The findings suggest that anxiety is a clinically meaningful correlate of poor outcome in the acute treatment of bipolar I disorder.

Influence of panic-agoraphobic spectrum symptoms on treatment response in patients with recurrent major depression.

OBJECTIVE: The authors tested the hypothesis that a lifetime history of panic-agoraphobic spectrum symptoms predicts a poorer response to depression treatment. METHOD: A threshold for clinically meaningful panic-agoraphobic spectrum symptoms was defined by means of receiver operating characteristic curve analysis of total scores on the Structured Clinical Interview for Panic-Agoraphobic Spectrum in a group of 88 outpatients with and without panic disorder. This threshold was then applied to a group of 61 women with recurrent major depression, who completed a self-report version of the same instrument, in order to compare treatment outcomes for patients above and below this clinical threshold. RESULTS: Women with high scores (> or =35) on the Panic-Agoraphobic Spectrum Self-Report were less likely than women with low scores (<35) to respond to interpersonal psychotherapy alone (43.5% versus 68.4%, respectively). Women with high scores also took longer (18.1 versus 10.3 weeks) to respond to a sequential treatment paradigm (adding a selective serotonin reuptake inhibitor when depression did not remit with interpersonal psychotherapy alone). This effect was only partially accounted for by the higher likelihood that patients with high scores required the addition of antidepressants. Although four domains from the Panic-Agoraphobic Spectrum Self-Report were individually associated with a longer time to remission, only stress sensitivity emerged as significant in multivariate regression analyses. CONCLUSIONS: A lifetime burden of panic-agoraphobic spectrum symptoms predicted a poorer response to interpersonal psychotherapy and an 8-week delay in sequential treatment response among women with recurrent depression. These results lend clinical validity to the spectrum construct and highlight the need for alternate psychotherapeutic and pharmacologic strategies to treat depressed patients with panic spectrum features.

Psychosocial functioning in women with premenstrual dysphoric disorder before and after treatment with sertraline or placebo.

BACKGROUND: The objective of this study was to evaluate the pretreatment psychosocial functioning of women with premenstrual dysphoric disorder (PMDD) and the effect of sertraline treatment on psychosocial functioning in these patients. METHOD: Two hundred forty-three women recruited from 12 university-affiliated sites and meeting DSM-IV criteria for PMDD completed 1 cycle of single-blind placebo and were randomly assigned to flexible dose sertraline or placebo for 3 cycles. Psychosocial functioning was assessed by the Daily Record of Severity of Problems (DRSP), the Social Adjustment Scale (SAS), and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q). RESULTS: SAS scores during the follicular phase were similar to SAS scores of community norms, whereas the pretreatment SAS and Q-LES-Q scores during the luteal phase were similar to scores of women with depressive disorders. Sertraline was significantly more effective than placebo in improving psychosocial functioning as measured by the SAS, the Q-LES-Q, and the 3 DRSP items of impaired productivity, interference with social activities, and interference with relationships with others. Improvement in psychosocial functioning assessed by SAS and Q-LES-Q correlated with improvement in symptomatology assessed by the Clinical Global Impressions-Improvement (CGI-I) scale and the Hamilton Rating Scale for Depression (HAM-D). Remitters (CGI-I score of 1) were more likely to function better at baseline and showed larger improvements in functioning and quality of life with treatment compared with nonremitters. CONCLUSION: Sertraline was superior to placebo in improving psychosocial functioning in women with PMDD as reflected by SAS, Q-LES-Q, and DRSP measures. Functional improvement correlated with improvement in premenstrual symptomatology and was apparent by the second cycle of treatment. Comparison of pretreatment SAS scores in women with PMDD with the scores of other populations of women documents the degree of luteal phase functional impairment in women with PMDD and a relative absence of follicular phase impairment.

Continuing medical education habits of US women physicians.

OBJECTIVES: To quantify the time women physicians spend on continuing medical education (CME) in total and by type of activity and to assess the impact of various demographic and professional characteristics on CME practices. METHODS: We analyzed CME habits among 4501 female physicians (a 59% response rate) using a 1994 national questionnaire-based survey, the Women Physicians' Health Study. RESULTS: US women physicians reported spending a monthly mean of 12.5 hours on CME, including 5.1 hours reading medical journals, 3.1 reading medical textbooks, 3.7 attending live CME lectures, 0.7 listening to CME audio tapes, and 0.4 watching medical television or videos. They also spent 0.9 hours per month learning from lay health media. Physicians with subspecialty training, medical school employment, and a non-US birthplace reported significantly (p < 0.05) more CME hours; age, ethnicity, region, specialty type, practice locale, career satisfaction, and board certification did not significantly predict reported CME hours. CONCLUSIONS: US women physicians reported spending an average of one-half hour each work day on CME, including about one hour per week reading medical journals, their most commonly reported CME activity.

Interpersonal psychotherapy and antidepressant medication: evaluation of a sequential treatment strategy in women with recurrent major depression.

BACKGROUND: Few data are available to guide treatment selection in major depression. With increasing pressure to maximize the efficiency and minimize the costs of treatment, it is important to have information that could guide treatment selection or point to treatment strategies that have a high probability of success. METHOD: We used a successive cohort approach to compare 2 highly similar groups of women with recurrent unipolar disorder (DSM-III-R or DSM-IV): one in which the combination of interpersonal psychotherapy (IPT) and pharmacotherapy was initiated at the outset of treatment and a second in which IPT alone was provided first and only those who did not remit with IPT alone were offered the combination treatment. RESULTS: In the group in which the combination was initiated at the outset of treatment (N = 180), the remission rate was 66%, comparable to the remission rate observed in most outpatient treatment studies of major depression. In contrast, among the women in the second cohort who were first treated with IPT alone and only those who did not remit were given combination therapy (N = 159), the remission rate was 79%, significantly greater than that observed in the group that received combination treatment from the outset (chi2 = 6.55, p = .02). CONCLUSION: These results suggest that the strategy of offering IPT to women with recurrent unipolar disorder and, in the absence of remission, adding antidepressant pharmacotherapy can be a highly effective treatment, one that may be particularly attractive to women in the childbearing years. Although slower in its onset of action, this sequential strategy is likely to enable the clear majority of such women to achieve a full remission of depressive symptoms.

Treatment of men with major depression: a comparison of sequential cohorts treated with either cognitive-behavioral therapy or newer generation antidepressants.

OBJECTIVE: This report compares response to cognitive-behavioral therapy (CBT) and pharmacotherapy in sequential cohorts of men with DSM-III-R major depression. METHOD: Patients were enrolled in consecutive standardized 16-week treatment protocols conducted in the same research clinic. The first group (N = 52) was treated with Beck's model of CBT, whereas the second group (N = 23) received randomized but open-label treatment with either fluoxetine (N = 10) or bupropion (N = 13). Crossover to the alternate medication was permitted after 8 weeks of treatment for antidepressant nonresponders. The patient groups were well matched prior to treatment. Outcomes included remission and nonresponse rates, as well as both independent clinical evaluations and self-reported measures of depressive symptoms. RESULTS: Despite limited statistical power to detect differences between treatments, depressed men treated with pharmacotherapy had significantly greater improvements on 4 of 6 continuous dependent measures and a significantly lower rate of nonresponse (i.e., 13% vs. 46%). The difference favoring pharmacotherapy was late-emerging and partially explained by crossing over nonresponders to the alternate medication. The advantage of pharmacotherapy over CBT also tended to be larger among the subgroup of patients with chronic depression. CONCLUSION: Results of prior research comparing pharmacotherapy and CBT may have been influenced by the composition of study groups, particularly the gender composition, the choice of antidepressant comparators, or an interaction of these factors. Prospective studies utilizing flexible dosing of modern antidepressants and, if necessary, sequential trials of dissimilar medications are needed to confirm these findings.

SEMA3A regulates developing sensory projections in the chicken spinal cord.

The present study explores the role of SEMA3A (collapsin-1) in the temporal and spatial regulation of developing sensory projections in the chick spinal cord. During development, SEMA3A mRNA (SEMA3A) is first expressed throughout the spinal gray matter, but disappears from the dorsal region when small caliber (trkA(+)) sensory axon collaterals first grow into the dorsal horn. In explant cultures of spinal cord segments with attached sensory ganglia, the spatial extent of SEMA3A expression varied in different explants, but in each case the growth of trkA(+) sensory collaterals was largely excluded from areas of SEMA3A expression. To test if SEMA3A had a direct effect on sensory axon growth, we injected recombinant protein into the explants before placing them in culture. Increased levels of SEMA3A substantially reduced the ingrowth of trkA(+) axons, whereas trkC(+) axon collaterals were not affected. Consistent with the insensitivity of trkC(+) collaterals to SEMA3A, these collaterals did not express neuropilin-1, a receptor for SEMA3A. The inhibitory effects of SEMA3A on trkA(+) axons within the spinal cord suggests that the fall in SEMA3A expression in the dorsal horn may contribute to the initiation of growth of these axons into gray matter. In addition, the observation that trkA(+) axons frequently grew close to but rarely over areas of SEMA3A expression suggests that semaphorin may act principally as a short-range guidance cue within the spinal cord.

The intersection of race, gender, and primary care: results from the Women Physicians' Health Study.

The Women Physicians' Health Study is a nationally distributed mailed questionnaire survey of a random sample of 4501 female physicians. We examined differences in the professional characteristics and personal health habits of minority women physicians compared to other women physicians, with regard to the choice of primary care specialties, type or location of practice site, and career satisfaction. Most women physicians were self-described as non-Hispanic white (77.4%), with 13% Asians, and few blacks (4.3%) or Hispanics (5.2%). Blacks and Hispanics were more likely to choose primary care specialties (61.6% and 57.9%, respectively, vs. 49.3% of whites, p < 0.05). Black and Hispanic physicians were most likely to practice in urban areas (71.8% and 72.2%, respectively, p < 0.001). Minority physicians were most likely to report spending some time each week on clinical work for which they did not expect compensation. Black physicians were least likely to report high levels of work control and were least likely to be satisfied with their careers. While most physicians were compliant with the examined recommendations of the U.S. Preventive Services Task Force, we did find significant differences by ethnicity in compliance with clinical breast exams, mammograms, and pap smears. In conclusion, there continues to be fewer blacks and Hispanics in the U.S. physician workforce than in the general population. Minority women physicians are more likely to provide primary care services in communities that have been traditionally underserved and may also report higher rates of career dissatisfaction.

PET imaging of serotonin 1A receptor binding in depression.

BACKGROUND: The serotonin-1A (5HT1A) receptor system has been implicated in the pathophysiology of major depression by postmortem studies of suicide victims and depressed subjects dying of natural causes. This literature is in disagreement, however, regarding the brain regions where 5HT1A receptor binding differs between depressives and controls and the direction of such differences relative to the normal baseline, possibly reflecting the diagnostic heterogeneity inherent within suicide samples. PET imaging using the 5HT1A receptor radioligand, [11C]WAY-100635, may clarify the clinical conditions under which 5HT1A receptor binding potential (BP) is abnormal in depression. METHODS: Regional 5HT1A receptor BP values were compared between 12 unmedicated depressives with primary, recurrent, familial mood disorders and 8 healthy controls using PET and [carbonyl-11C]WAY-100635. Regions-of-interest (ROI) assessed were the mesiotemporal cortex (hippocampus-amygdala) and midbrain raphe, where previous postmortem studies suggested 5HT1A receptor binding is abnormal in depression. RESULTS: The mean 5HT1A receptor BP was reduced 41.5% in the raphe (p < .02) and 26.8% in the mesiotemporal cortex (p < .025) in the depressives relative to the controls. Post hoc comparisons showed the abnormal reduction in 5HT1A receptor BP was not limited to these regions, but extended to control ROI in the occipital cortex and postcentral gyrus as well. The magnitude of these abnormalities was most prominent in bipolar depressives (n = 4) and unipolar depressives with bipolar relatives (n = 4). CONCLUSIONS: Serotonin-1A receptor BP is abnormally decreased in the depressed phase of familial mood disorders in multiple brain regions. Of the regions tested, the magnitude of this reduction was most prominent in the midbrain raphe. Converging evidence from postmortem studies of mood disorders suggests these reductions of 5HT1A receptor BP may be associated with histopathological changes involving the raphe.
