Genetics professionals' experiences with grief and loss: implications for support and training.

This study was designed to determine the degree to which clinical genetics professionals are comfortable with grief and loss, whether discomfort with grief and loss is associated with clinician distress, and what factors predict comfort with grief and loss for the purpose of developing recommendations for support and training. We surveyed 300 clinical geneticists (MDs), genetic counselors (GCs) and genetic nurses randomly selected from their professional associations. Out of 225 eligible clinicians, 172 completed surveys (76% response rate). The vast majority of respondents have clinical interactions with patients and families who are experiencing grief, loss and/or death. However, nearly 20% of respondents reported that they did not feel 'comfortable in the presence of grief and loss'. Twenty-nine percent of respondents disagree or strongly disagree that they 'have been adequately trained to address issues of death, dying, grief/bereavement, and end of life care'. Reported discomfort with grief and loss was strongly correlated with clinician distress. Predictors of comfort with grief and loss included perceived adequacy of training, tolerance for uncertainty, significant personal experiences of loss and deriving meaning from patient care. In conclusion, as follows. A significant minority of clinical genetics professionals experience discomfort in the presence of grief and loss, and feel inadequately prepared for such experiences. Greater attention should be paid to training clinicians in how to deal with grief and loss, and supporting them through such difficult experiences in an effort to reduce their distress.

Predictors of variability in urinary incontinence and overactive bladder symptoms.

AIMS: We used data from the General Longitudinal Overactive Bladder Evaluation (GLOBE) to understand predictors of variation in urgency and urinary incontinence (UI) symptoms over time. METHODS: A random sample of Geisinger Clinic primary care patients (men and women) 40+ years of age were recruited for a survey of bladder control symptoms at baseline and 12 months later. Symptom questions used a 4-week recall period. Composite scores were derived for urgency and UI frequency. Logistic regression was used to evaluate predictors of variation in scores at cross-section and longitudinally. RESULTS: A majority of those with UI symptoms and almost 40% of those with urgency symptoms reported episodes of once a week or less often; 17% had symptoms a few times a week or more often. Twenty-one percent with urgency symptoms and 25% with UI symptoms at baseline did not have active symptoms 12 months later. The strongest predictors of active symptoms at follow-up were baseline symptom score and duration of time since first onset of symptoms. Of those with no urgency symptoms at baseline, 22% had urgency at 12 months. Among those with no UI symptoms at baseline, 13% had UI symptoms 12 months later. Among the latter, age (males only) and BMI were the strongest predictors of symptoms at follow-up. CONCLUSIONS: Inter-individual and intra-individual occurrences of urgency and UI symptoms are highly variable in the general population. Use of established predictors to select individuals with less variability in symptoms may help to reduce placebo rates in clinical trials.

Validity and reliability of the Migraine-Treatment Optimization Questionnaire.

Our aim was to establish the validity and reliability of a patient-rated Migraine Treatment Optimization Questionnaire (M-TOQ) in primary care. Patients who met International Classification of Headache Disorders, 2nd edn criteria for migraine completed a 19-item questionnaire containing candidate items for the M-TOQ, and three questionnaires designed to test convergent/construct validity [Migraine Disability Assessment Scale (MIDAS), Headache Impact Test (HIT)-6 and Migraine-Specific Quality of Life Scale (MSQoL)]. A 15-item (M-TOQ-15) and a five-item (M-TOQ-5) questionnaire were derived. Two hundred and fifty-three adult patients were recruited. Five treatment optimization domains were identified: functioning, rapid relief, consistency of relief, risk of recurrence and tolerability; with Cronbach alphas of 0.70-0.84. The Cronbach alpha for M-TOQ-15 was 0.85, and it correlated well with MIDAS, HIT-6 and MSQoL (r = 0.33-0.44). The Cronbach alpha for M-TOQ-5 was 0.66, and it also correlated well with the three questionnaires (r = 0.33-0.41). The utility of the M-TOQ for assessing treatment benefit in research (M-TOQ-15) and primary care (M-TOQ-5) should be further validated.

Migraine, quality of life, and depression: a population-based case-control study.

OBJECTIVE: This study reports on the influence of migraine and comorbid depression on health-related quality of life (HRQoL) in a population-based sample of subjects with migraine and nonmigraine controls. METHODS: Two population-based studies of similar design were conducted in the United States and United Kingdom. A clinically validated, computer-assisted telephone interview was used to identify individuals with migraine, as defined by the International Headache Society, and a nonmigraine control group. During follow-up interviews, 389 migraine cases (246 US, 143 UK) and 379 nonmigraine controls (242 US, 137 UK) completed the Short Form (SF)-12, a generic HRQoL measure, and the Primary Care Evaluation of Mental Disorders, a mental health screening tool. The SF-12 measures HRQoL in two domains: a mental health component score (MCS-12) and a physical health component score (PCS-12). RESULTS: In the United States and United Kingdom, subjects with migraine had lower scores (p < 0.001) on both the MCS-12 and PCS-12 than their nonmigraine counterparts. Significant differences were maintained after controlling for gender, age, and education. Migraine and depression were highly comorbid (adjusted prevalence ratio 2.7, 95% CI 2.1 to 3. 5). After adjusting for gender, age, and education, both depression and migraine remained significantly and independently associated with decreased MCS-12 and PCS-12 scores. HRQoL was significantly associated with attack frequency (for MCS-12 and PCS-12) and disability (MCS-12). CONCLUSIONS: Subjects with migraine selected from the general population have lower HRQoL as measured by the SF-12 compared with nonmigraine controls. Further, migraine and depression are highly comorbid and each exerts a significant and independent influence on HRQoL.

Migraine in the United States: epidemiology and patterns of health care use.

OBJECTIVE: To determine the prevalence and distribution of migraine in the United States as well as current patterns of health care use. METHODS: A random-digit-dial, computer-assisted telephone interview (CATI) survey was conducted in Philadelphia County, PA, in 1998. The CATI identifies individuals with migraine (categories 1.1 and 1.2) as defined by the diagnostic criteria of the International Headache Society with high sensitivity (85%) and specificity (96%). Interviews were completed in 4,376 subjects to identify 568 with migraine. Those with 6 or more attacks per year (n = 410) were invited to participate in a follow-up interview about health care utilization and family impact of migraine; 246 (60.0%) participated. RESULTS: The 1-year prevalence of migraine was 17.2% in females and 6.0% in males. Prevalence was highest between the ages of 30 and 49. Whereas 48% of migraine sufferers had seen a doctor for headache within the last year (current consulters), 31% had never done so in their lifetimes and 21% had not seen a doctor for headache for at least 1 year (lapsed consulters). Of current or lapsed consulters, 73% reported a physician-made diagnosis of migraine; treatments varied. Of all migraine sufferers, 49% were treated with over-the-counter medications only, 23% with prescription medication only, 23% with both, and 5% with no medications at all. CONCLUSION: Relative to prior cross-sectional surveys, epidemiologic profiles for migraine have remained stable in the United States over the last decade. Self-reported rates of current medical consultation have more than doubled. Moderate increases were seen in the percentage of migraine sufferers who use prescription medications and in the likelihood of receiving a physician diagnosis of migraine.

An international study to assess reliability of the Migraine Disability Assessment (MIDAS) score.

BACKGROUND: The Migraine Disability Assessment (MIDAS) instrument is a five-item questionnaire developed to measure headache-related disability and improve doctor-patient communication about the functional consequences of migraine. OBJECTIVES: To examine the test-retest reliability and internal consistency of the five items and of the overall MIDAS score in population-based samples of migraine sufferers in two countries and to compare consistency across countries. METHODS: Using a clinically validated telephone interview, population-based samples of migraine-headache sufferers were identified in the United States (Baltimore, MD) and the United Kingdom (Merton and Sutton, Surrey). Eligible individuals completed the MIDAS questionnaire on two occasions an average of 3 weeks apart. The MIDAS score is derived from five questions about missed time from work and household work (one question each about missed days and days with at least 50% reduced productivity) and missed days of nonwork activities. RESULTS: A total of 97 migraine-headache sufferers from the United States and 100 from the United Kingdom completed the MIDAS questionnaire twice. Mean and median item values and overall MIDAS scores were similar between the United States and the United Kingdom. Test-retest Spearman correlations of individual items ranged from 0.46 to 0.78. No significant differences in item-specific correlations were observed between the United States and United Kingdom. The test-retest Pearson correlation of the MIDAS score (i.e., sum of lost days and reduced-effectiveness days in each domain) was 0.80 in the United States and 0.83 in the United Kingdom. The Cronbach alpha, a measure of internal consistency, was 0.76 in the United States and 0.73 in the United Kingdom. CONCLUSIONS: This is the first international population-based study to assess the reliability of a disability-related illness severity score for migraine. The reliability and internal consistency of the Migraine Disability Assessment score are similar to that of a previous questionnaire (Headache Impact Questionnaire). However, the Migraine Disability Assessment score requires fewer questions, is easier to score, and provides intuitively meaningful information on lost days of activity in three domains.

Physician opinion about electronic publications.

PURPOSE: Many medical journals are currently offering physicians the option to subscribe electronically, allowing readers access by means of the Internet. However, physicians' opinions about this innovation are not known. This exploratory study was designed to learn more about physicians' opinions and attitudes regarding electronic publications. SUBJECTS AND METHODS: A three-page questionnaire was developed to survey all physicians (faculty and house officers) at a large university-affiliated teaching hospital in Baltimore, Maryland. The questionnaire explored many of the features that make electronic journals distinct from printed journals. RESULTS: Of the 314 physicians surveyed, 255 (81%) returned a completed questionnaire. The mean (+/- SD) age of the respondents was 41 +/- 10 years, 164 (65%) were male, and 50 (20%) were house officers. Twenty-six percent of respondents (n = 66) thought that electronic journals would lower the quality of the medical literature, and 25% (n = 63) believed that the prestige of authorship would be lessened. Seventy to eighty percent of physicians responded that electronic journals would decrease clutter in their offices and homes, be more environmentally friendly than the current system, make it easier to locate research reports that they had read, and offer the benefit of linkage to related articles. Seventy-four percent of physicians (n = 188) were concerned about losing the convenience of being able to read a printed journal anywhere. In multivariate analyses, female sex, being a faculty member (vs house officer), fewer publications, better computer skills, and more frequent use of the Internet were independently associated with positive attitudes toward various aspects of electronic journals. CONCLUSIONS: Physicians responded favorably to the many potential values and applications of electronic publications but were most concerned with the loss of the convenience that printed journals offer.

Medications used by children with asthma living in the inner city.

OBJECTIVE: The purpose of the study was to examine medication use reported by families participating in an urban school-based community intervention program and to relate this use to other social and medical variables. DESIGN: The design of the study was a cross-sectional questionnaire survey. SETTING: Patients and their families recruited from elementary schools in a community setting were interviewed between December 1991 and January 1992. PARTICIPANTS: A total of 508 children with asthma were identified by school health records and teacher surveys. Their families confirmed the diagnosis and agreed to enter the study. Questionnaires were completed by 392 families. INTERVENTION: The 392 families participated in a controlled trial of asthma education after providing the data that are the basis of this report. RESULTS: More than half of the children took two or more medications for asthma. Thirty-one percent took theophylline alone or in combination with an adrenergic agent; 11% took some form of daily antiinflammatory medication, either cromolyn (8%) or inhaled steroids (3%). The pattern of medication use related to measures of severity and to regular visits to physicians or nurses. In general, however, children were undermedicated. A total of 78 children (20%) reported no medication or over-the-counter medication use, although 37% reported asthma severe enough to be associated with >/=20 days of school missed per month, and 37% had had an emergency room visit for asthma in the past 6 months. More than half of children >/=9 years old supervised their own medication. CONCLUSIONS: We concluded that undermedication is common in poor children with asthma living in urban areas. Antiinflammatory medications are used less commonly than in the general population, and theophylline is used more often. School children may be likely to supervise their own medication.

Measurement of chromosomal aberrations, sister chromatid exchange, hprt mutations, and DNA adducts in peripheral lymphocytes of human populations at increased risk for cancer.

Using a multidisciplinary approach, we have measured various indicators of DNA damage in peripheral lymphocytes of human populations potentially at increased risk for cancer. Sister chromatid exchanges (SCE) and polycyclic aromatic hydrocarbon (PAH)-DNA adducts were evaluated in a group of firefighters; chromosomal aberrations and hprt mutations were evaluated in a group of cancer patients undergoing radioimmunoglobulin therapy (RIT); SCE and acrolein-modified DNA were measured in cancer chemotherapy patients and in pharmacists preparing chemotherapy prescriptions; and SCE and PAH-DNA adducts are being measured in U.S. army troops stationed in Kuwait. Our results indicate that both SCE and PAH-DNA adduct levels were not elevated in firefighters, but that other factors such as smoking status and race were risk factors for increased SCE and PAH-DNA adducts. RIT was found to increase background rates of chromosome-type aberrations and frequencies of hprt mutations and there was a strong correlation between levels of therapy-induced chromosome damage sustained in vivo and in vitro sensitivity to radiation-induced chromosome damage. Peripheral blood lymphocytes of cancer patients treated with cyclophosphamide showed higher levels of SCE and had a higher incidence of acrolein adducts in DNA. Lymphocytes from pharmacists preparing antineoplastic drugs were found to acquire increased in vitro sensitivity to SCE induction by phosphoramide mustard with increased lifetime duration of drug handling. A prospective, longitudinal study was performed to identify environmental factors that modulate genetic damage in breast cancer patients. Women with benign breast masses and no apparent disease served as controls. Mutant frequency, cloning efficiency, and chromosomal aberration frequency did not differ significantly among the three groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Nebulizer use in inner-city children with asthma: morbidity, medication use, and asthma management practices.

OBJECTIVE: To assess the frequency of nebulizer use, describe morbidity and patterns of medication administration, and examine the potential relationships between inhaled anti-inflammatory medication administration, asthma morbidity, and asthma management practices in children with asthma using a nebulizer compared with children with asthma not using a nebulizer. RESEARCH DESIGN: A cross-sectional, descriptive survey of previous events. SETTING: Elementary schools and participants' homes in Baltimore, Md, and Washington, DC. PARTICIPANTS: Six hundred eighty-six families of children aged 5 to 12 years with a diagnosis of at least mild, persistent asthma. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Asthma morbidity, health care utilization, pattern of asthma medication administration, nebulizer use, and asthma management data were collected by telephone survey administered to caregivers. Nebulizer use was defined as use at least 1 or more days per month during the last 6 months. Of 686 children identified, 231 (33%) reported current nebulizer use. Nebulizer users had significantly increased lifetime hospital admissions, hospitalizations, and emergency department visits in the last 6 months compared with nonnebulizer users. Inhaled corticosteroid administration was low for both groups (nonnebulizer users, 8%; nebulizer users, 15%). In the nebulizer users group, administration of inhaled anti-inflammatory medications was associated with increased asthma morbidity (increased hospitalizations, days and nights with symptoms, and oral steroid use). CONCLUSIONS: Nebulizer use by inner-city children with asthma is higher than anticipated but is not associated with reduced asthma morbidity. This group of high-risk children was undertreated with inhaled corticosteroids for long-term control of asthma despite reports of adequate monitoring by a primary care physician.

Maternal depressive symptoms and emergency department use among inner-city children with asthma.

CONTEXT: Inner-city minority children with asthma use emergency departments (ED) frequently. OBJECTIVE: To examine whether maternal depressive symptoms are associated with ED use. DESIGN, SETTING, AND PATIENTS: Baseline and 6-month surveys were administered to mothers of children with asthma in inner-city Baltimore, Md, and Washington, DC. MAIN OUTCOME MEASURES: Use of the ED at 6-month follow-up was examined. Independent variables included asthma morbidity, age, depressive symptoms, and other psychosocial data. RESULTS: Among mothers, nearly half reported significant levels of depressive symptoms. There were no demographic or asthma-related differences between the children of mothers with high and low depressive symptoms. However, in bivariate analyses, mothers with high depressive symptoms were 40% (prevalence ratio [PR], 1.4; 95% confidence interval [CI], 1.0-3.6; P =.04) more likely to report taking their child to the ED. Mothers aged 30 to 35 years were more than twice as likely (PR, 2.2; 95% CI, 1.9-9.3; P =.001) to report ED use, as were children with high morbidity (PR, 1.9; 95% CI, 1.4-7.1; P =.006). Child age and family income were not predictive of ED use. After controlling for asthma symptoms and mother's age, mothers with depressive symptoms were still 30% more likely to report ED use. CONCLUSIONS: Depression is common among inner-city mothers of children with asthma. Beyond asthma morbidity, maternal age and depressive symptoms are strong predictors of reports of ED visits. Identifying and addressing poor psychological adjustment in mothers may reduce unnecessary ED visits and optimize asthma management among inner-city children.

Relationship between mood and blood pressure in the natural environment: an adolescent population.

We examined the relation between psychological variables and blood pressure (BP) as 28 adolescents engaged in their customary activities over a 24-hr period in their natural environment. Each subject had previously participated in a laboratory study of cardiovascular reactivity. During the ambulatory monitoring period, subjects monitored mood state, perceptions of the environment, and ambulatory BP at 30-min intervals. Mood ratings and BP were averaged across the waking hours. Systolic blood pressure (SBP) reactivity to laboratory stressors was significantly correlated with average SBP in the home environment. Ambulatory SBP was positively associated with worried, hostile, depressed, and tense mood ratings as well as perceptions of the environment as hostile, demanding, and noisy. Ambulatory diastolic blood pressure was correlated with hostile, depressed, and upset mood ratings as well as with hostile and demanding perceptions of the environment. In general, average ambulatory BP appeared to be associated with negative emotions and perceptions of the environment.

Job turnover and its correlates among residency program directors in internal medicine: a three-year cohort study.

PURPOSE: In 1983, 43% of internal medicine residency program directors had held their positions for less than three years. The purposes of this study were to determine the job turnover rate for internal medicine program directors, and the characteristics of program directors and residency programs that are associated with job turnover. METHOD: In October 1996, questionnaires were sent to all non-military internal medicine residency program directors in the continental United States listed by the Accreditation Council for Graduate Medical Education (ACGME). The questionnaire covered demographics, program characteristics, and job satisfaction. In October 1999, an updated ACGME list was used to contact programs to verify changes in program directors and determine the dates of change. RESULTS: A total of 262 usable responses were received. At the beginning of the study, 49% of the respondents had been on the job for three years or less, and 74 (29%) were no longer program directors three years later. Overall job satisfaction was highly associated (p <.01) with turnover. Multivariate Cox regression modeling yielded four variables independently associated with turnover: low satisfaction with colleague relationships (hazard ratio = 3.2, 95% CI = 1.6-6.4), a high percentage of administrative work time (HR = 2.9, 95% CI = 1.4-6.2), perceiving the job as a "stepping stone" (HR = 1.8, 95% CI = 1.0-3.2), and having had formal training to deal with problem residents (HR = 0.6, 95% CI = 0.4-1.1). Respondents with burnout, with the titles of program director and chair or department chief, and with less than two years on the job had nonsignificant trends toward job turnover. Variables not associated with turnover included gender, rank, salary, and program size. CONCLUSIONS: Yearly turnover for internal medicine residency program directors is substantial. The four independent predictors of turnover identified in this study should be of interest to institutions recruiting or retaining program directors and to aspiring program directors.

A job-satisfaction measure for internal medicine residency program directors.

PURPOSE: To develop a job-satisfaction measure that encompasses the multifaceted job of internal medicine residency program directors. METHOD: Questions were devised to measure program directors satisfaction with various facets of their jobs. In 1996, the authors surveyed all non-military internal medicine program directors in the United States. RESULTS: Of the program directors surveyed, 301 (78%) responded. More respondents than non-respondents held the title of department chairperson in addition to the title of program director (22% vs 7%). Factor analysis and correlation analysis yielded a multifaceted measure (termed PD-Sat) composed of 20 questions and six facets (work with residents, colleague relationships, resources, patient care, pay, and promotion) that made sense based on literature review and discussions with program directors (face validity). The PD-Sat had good internal reliability (Cronbach's alpha = .88), as had each of its six facets (Cronbach's alphas = .60-.90). The six facets correlated modestly with one another (Pearson's r2 = .12-.67), suggesting they were measuring different aspects of a common concept. The PD-Sat correlated significantly with an established four-question global job-satisfaction scale used in previous studies (Pearson's r2 = .33) demonstrating concurrent validity. Scores on the PD-Sat predicted whether program directors were considering, seeking, or making a job change (predictive validity). The PD-Sat performed comparably well in subsets of program directors who were and were not department chairs, suggesting that it might be applicable to different populations of program directors. CONCLUSION: The authors have developed a new facet-specific job-satisfaction measure that is reliable and valid for assessing the job satisfaction of internal medicine program directors. Because job descriptions for program directors in other specialties are similar, it may also be useful in these populations.

Negative affect, gender, and expressive style predict elevated ambulatory blood pressure in adolescents.

Excessive blood pressure elevations during daily activities increase cardiovascular risk and may be related to individual differences in emotionality and expressive style. Emotional traits and ambulatory blood pressure were measured during a typical school day in 228 Black and White adolescents at risk of developing essential hypertension. Trait affect (depression, anger) predicted prevailing blood pressure levels; this association was moderated by gender, social setting (in classroom vs. with friends), and nonverbal expressive style. Relationships between emotion and blood pressure were not explained by obesity, smoking, or alcohol use. The uniform environment and regimen of the school made it possible to attribute variations in prevailing blood pressure to personality differences involving ways adolescents perceive and negotiate their social world.

Evidence for acrolein-modified DNA in peripheral blood leukocytes of cancer patients treated with cyclophosphamide.

Monitoring human populations for specific DNA modifications has been made possible by developing highly sensitive immunoassays employing antibodies specific for carcinogen-DNA adducts. While these techniques have been used to follow occupationally and environmentally exposed populations, results have been limited by the lack of exposure data with which to correlate adduct formation. Cancer patients treated with precisely known doses of anticancer drugs can be studied to examine the association between drug dose and adduct formation. This study examined acrolein-modified DNA in patients treated with the anticancer drug cyclophosphamide (CP) and in newly diagnosed patients prior to treatment. Employing 2 different detection methods, enzyme-linked immunosorbent assay (ELISA) and immuno-dot blot (IDB), acrolein-modified DNA was identified in a total of 6 of 12 (50%) treated patients and in 0 of 15 untreated patients. Formation of acrolein-modified DNA was examined as a function of lifetime CP dose, recent CP dose, time since last treatment, regime of treatment, and smoking history; however no clear trends were observed.

Baseline and phosphoramide mustard-induced sister-chromatid exchanges in cancer patients treated with cyclophosphamide.

Determinations of baseline sister-chromatid exchanges (SCE) have been used extensively as indicators of previous mutagen exposure in both animals and humans. Hypersensitivity to mutagen-induced SCE levels has also been studied in a variation on the basic technique as an indication of previous mutagen exposure in a stressed or provocative test system. The genotoxicity of the alkylating anti-cancer drugs including cyclophosphamide (CP) has been examined previously by determining baseline SCEs in peripheral blood lymphocytes from treated cancer patients. This study examined the in-vivo genotoxic effects of CP therapy by comparing baseline and phosphoramide mustard (PM)-induced SCEs in therapeutically (in-vivo) treated cancer patients with SCE levels in newly diagnosed, but not treated patients. Therapeutically treated patients showed statistically higher baseline SCE frequencies than untreated control patients with a mean SCE/cell of 6.95 vs. 5.25, p less than 0.016. When net SCE values (induced minus baseline) were determined in PM-exposed cells in-vitro both at low dose (0.1 microgram/ml PM) and high dose (0.25 microgram/ml PM) however, the difference was not significant between therapeutically treated and untreated control patients. The return to control SCE levels as a function of time since last therapeutic treatment was also evaluated and no difference was found between the rate of decline of PM-induced SCEs and baseline SCE levels over time.

Baseline and phosphoramide mustard-induced sister-chromatid exchanges in pharmacists handling anti-cancer drugs.

Determinations of baseline and mutagen-induced sister-chromatid exchanges (SCE) have been used as indicators of previous mutagen exposure in several human populations. Mutagen-induced SCE is based on the premise that a genetic outcome may depend not only on a present exposure, but also on a cell's "memory" of previous exposure. The genotoxicity of some anti-cancer drugs including cyclophosphamide (CP) has been studied by determining baseline and mutagen-induced SCE in peripheral blood lymphocytes in treated cancer patients. This study examined the in vivo genotoxic effects of occupational exposure to anti-cancer drug handling by relating baseline and phosphoramide mustard (PM) -induced SCE levels with duration of anti-cancer drug handling as a surrogate for anti-cancer drug exposure dose. The mean baseline SCE for the population was 5.19 +/- 0.17 and was not correlated with duration of drug handling. However, a strong correlation was demonstrated between inducible SCE values and life-time duration of drug handling with r = 0.63 (p less than 0.0001 for low-dose PM challenge (0.1 mg/ml PM) and r = 0.67 (p less than 0.0001) for high-dose PM challenge (0.25 mg/ml PM). A similar relationship was seen for PM-induced SCE and duration of anti-cancer drug handling for the workers' present job with correlations obtained being r = 0.63 (p less than 0.0001) for low-dose PM and r = 0.59 (p less than 0.0001) for high dose PM. The short-lived nature of the baseline SCE lesion is discussed as a limitation in population surveillance studies, as it reflects primarily recent mutagen exposure and persists only for days to weeks after exposure. The induced SCE measure is postulated to provide an integrating dosimeter of remote previous exposure, improving upon the current limitation of the baseline SCE measure and allowing the "unmasking" of previous exposure in a provocative framework.

Schooling, employment, and idleness in young adults with serious physical health conditions: effects of age, disability status, and parental education.

PURPOSE: Education, employment, and "idleness" in young adults with ongoing physical health conditions were examined in relation to parents' education and respondent's age and co-existing disabilities. METHODS: Telephone interviews were conducted with 421 individuals aged 20-24 years randomly drawn from public health programs in two midwestern states. In addition to a chronic health condition, 18% of the sample also had mental retardation, 21% also had a physical disability (but no retardation), and 11% also had a learning disability (but no mental retardation or physical disability). Youth were considered "idle" if they were not in school, not employed, not married, and had no children. RESULTS: Thirty-seven percent of the sample were enrolled in an educational program, and 48% were employed either part-time or full-time. Seventeen percent were both in school and employed, 50% were in school or employed, and 33% were neither in school nor working. Overall, 23% of the sample were idle. Youth with mental retardation were two to three times more likely to be in school compared to youth with a chronic physical condition alone. Youth with mental retardation and physical disabilities were less likely to be employed and more likely to be idle compared to youth with only a chronic condition. Parental education affected rates of schooling and employment. Compared to a general population sample of youth in the same states, youth with ongoing health problems were at higher risk for idleness. CONCLUSIONS: Youth with chronic health conditions and either mental retardation or physical disabilities are at higher risk for idleness compared to youth with a chronic condition alone or to youth in general.

Sociotropic cognition moderates blood pressure response to interpersonal stress in high-risk adolescent girls.

This article tests the hypothesis that 'sociotropic cognition'--heightened preoccupation with being accepted by others--increase vulnerability to cardiovascular stress in females. Adolescent girls (55 African-American; 23 Caucasian) at increased risk of developing essential hypertension due to persisting high normal blood pressure, completed measures of sociotropic cognition, social competence, trait affect and social support. Later, their blood pressure and heart rate were measured during non-social stress (mirror image tracing) and interpersonal stress [Social Competence Interview (SCI)]. Comparisons of blood pressure responses to the tasks disclosed a significant Task main effect, replicating a previous finding that blood pressure is elevated more by SCI than by non-social stress. When Sociotropy was introduced as a moderator, however, a significant Task by Sociotropy interaction indicated that the comparatively greater reactivity to SCI occurred mainly in girls who exhibited high levels of sociotropic thinking. Cognitive sociotropy was associated with a profile of social emotional and environmental deficits suggesting increased susceptibility to chronic stress and impaired coping.
