RESUMO

INTRODUCTION: Similar Patient-Reported Outcomes (PROs) at diagnosis for localized prostate cancer among countries may indicate that different treatments are recommended to the same profile of patients, regardless the context characteristics (health systems, medical schools, culture, preferences…). The aim of this study was to assess such comparison. METHODS: We analyzed the EPIC-26 results before the primary treatment of men diagnosed of localized prostate cancer from January 2017 onwards (revised data available up to September 2019), from a multicenter prospective international cohort including seven regions: Australia/New Zealand, Canada, Central Europe (Austria / Czech Republic / Germany), United Kingdom, Italy, Spain, and the United States. The EPIC-26 domain scores and pattern of three selected items were compared across regions (with Central Europe as reference). All comparisons were made stratifying by treatment: radical prostatectomy, external radiotherapy, brachytherapy, and active surveillance. RESULTS: The sample included a total of 13,483 men with clinically localized or locally advanced prostate cancer. PROs showed different domain patterns before treatment across countries. The sexual domain was the most impaired, and the one with the highest dispersion within countries and with the greatest medians' differences across countries. The urinary incontinence domain, together with the bowel and hormonal domains, presented the highest scores (better outcomes) for all treatment groups, and homogeneity across regions. CONCLUSIONS: Patients with localized or locally advanced prostate cancer undergoing radical prostatectomy, EBRT, brachytherapy, or active surveillance presented mainly negligible or small differences in the EPIC-26 domains before treatment across countries. The results on urinary incontinence or bowel domains, in which almost all patients presented the best possible score, may downplay the baseline data role for evaluating treatments' effects. However, the heterogeneity within countries and the magnitude of the differences found across countries in other domains, especially sexual, support the need of implementing the PRO measurement from diagnosis.

RESUMO

BACKGROUND: Menopausal symptoms (e.g., hot flashes, vaginal dryness, and stress urinary incontinence) are very common in breast cancer survivors and cannot be managed with standard estrogen replacement therapy (ERT) in these patients. The purpose of this study was to test the efficacy of a comprehensive menopausal assessment (CMA) intervention program in achieving relief of symptoms, the improvement in quality of life (QOL), and sexual functioning in breast cancer survivors. METHODS: Using a two-group, randomized controlled design, we assigned 76 postmenopausal breast cancer survivors with at least one severe target symptom either to the intervention group or to a usual-care group. Seventy-two women were evaluable at the end of the study period. The CMA intervention, delivered by a nurse practitioner, focused on symptom assessment, education, counseling and, as appropriate, specific pharmacologic and behavioral interventions for each of the three target symptoms. Psychosocial symptoms were assessed with the use of a self-report screening instrument, and distressed women were referred for counseling if needed. The intervention took place over a 4-month period. Outcomes measured were scores on a composite menopausal symptom scale, the RAND Short Form Health Survey Vitality Scale, and the Cancer Rehabilitation Evaluation System (CARES) Sexual Functioning Scale at baseline and at 4-month follow-up. All statistical tests were two-sided and were performed at the alpha =. 05 significance level. RESULTS: Patients receiving the intervention demonstrated statistically significant improvement (P =.0004) in menopausal symptoms but no significant change in vitality (P =.77). Sexual functioning was statistically significantly improved (P =.04) in the treatment group compared with the usual-care group. CONCLUSIONS: A clinical assessment and intervention program for menopausal symptom management in breast cancer survivors is feasible and acceptable to patients, leading to reduction in symptoms and improvement in sexual functioning. Measurable improvement in a general QOL measure was not demonstrated.

RESUMO

BACKGROUND: Tissue-sparing approaches to primary treatment and reconstructive options provide improved cosmetic outcomes for women with breast cancer. Earlier research has suggested that conservation or restitution of the breast might mitigate the negative effects of breast cancer on women's sexual well-being. Few studies, however, have compared psychosocial outcomes of women who underwent lumpectomy, mastectomy alone, or mastectomy with reconstruction. To address some of these issues, we examined women's adaptation to surgery in two large cohorts of breast cancer survivors. METHODS: A total of 1957 breast cancer survivors (1-5 years after diagnosis) from two major metropolitan areas were assessed in two waves with the use of a self-report questionnaire that included a number of standardized measures of health-related quality of life, body image, and physical and sexual functioning. All P: values are two-sided. RESULTS: More than one half (57%) of the women underwent lumpectomy, 26% had mastectomy alone, and 17% had mastectomy with reconstruction. As in earlier studies, women in the mastectomy with reconstruction group were younger than those in the lumpectomy or mastectomy-alone groups (mean ages = 50.3, 55.9, and 58.9, respectively; P: =.0001); they were also more likely to have a partner and to be college educated, affluent, and white. Women in both mastectomy groups complained of more physical symptoms related to their surgeries than women in the lumpectomy group. However, the groups did not differ in emotional, social, or role function. Of interest, women in the mastectomy with reconstruction group were most likely to report that breast cancer had had a negative impact on their sex lives (45.4% versus 29.8% for lumpectomy and 41.3% for mastectomy alone; P: =. 0001). CONCLUSIONS: The psychosocial impact of type of primary surgery for breast cancer occurs largely in areas of body image and feelings of attractiveness, with women receiving lumpectomy experiencing the most positive outcome. Beyond the first year after diagnosis, a woman's quality of life is more likely influenced by her age or exposure to adjuvant therapy than by her breast surgery.

RESUMO

Methamphetamine (MA) users are assumed to have a high burden of tooth decay. Less clear is how the distribution and severity of dental caries in MA users differ from the general population. Using a covariate-balancing propensity score strategy, we investigated the differential effects of MA use on dental caries by comparing the patterns of decayed, missing, and filled teeth in a community sample of 571 MA users with a subset of 2,755 demographically similar control individuals selected from a National Health and Nutrition Examination Survey (NHANES) cohort. Recruited over a 2-y period with a stratified sampling protocol, the MA users underwent comprehensive dental examinations by 3 trained and calibrated dentists using NHANES protocols. Propensity scores were estimated with logistic regression based on background characteristics, and a subset of closely matched subjects was stratified into quintiles for comparisons. MA users were twice as likely to have untreated caries (odds ratio [OR] = 2.08; 95% confidence interval [95% CI]: 1.55 to 2.78) and 4 times more likely to have caries experience (OR = 4.06; 95% CI: 2.24 to 7.34) than the control group of NHANES participants. Additionally, MA users were twice as likely to have 2 more decayed, missing, or filled teeth (OR = 2.08; 95% CI: 1.29 to 2.79) than the NHANES participants. The differential involvement of the teeth surfaces in MA users was quite distinctive, with carious surface involvement being highest for the maxillary central incisors, followed by maxillary posterior premolars and molars. Users injecting MA had significantly higher rates of tooth decay compared with noninjectors (P = 0.04). Although MA users experienced decayed and missing dental surfaces more frequently than NHANES participants, NHANES participants had more restored surfaces, especially on molars. The high rates and distinctive patterns of dental caries observed could be used 1) to alert dentists to covert MA use in their patients and 2) as the basis for comprehensive management strategies.

RESUMO

PURPOSE: To identify variables that might be predictive of sexual health (interest, dysfunction, and satisfaction) in a large sample of breast cancer survivors, with a validation conducted in a second, independent sample. PATIENTS AND METHODS: On the basis of a conceptual framework of sexual health in breast cancer survivors, we performed multivariable regression analyses to estimate sexual interest, dysfunction, and satisfaction in both samples. Additional analyses were performed using stepwise regression and recursive partitioning to explore in each sample the relative contributions of the independent variables toward predicting the outcome measures. RESULTS: The models for sexual interest accounted for at least 33% of the variance, and the significant predictors common to the two samples were having a new partner since the diagnosis of breast cancer, mental health score, and body image score. For sexual dysfunction, the models in the two samples explained at least 33% of the variance, and the common significant predictors were vaginal dryness, past chemotherapy use, and having a new partner since diagnosis. The sexual satisfaction models explained at least 27% of the variance, with the common significant predictors being the quality of the partnered relationship and sexual problems in the partner. CONCLUSION: Among the predictors of sexual health, several are mutable (vaginal dryness, emotional well-being, body image, the quality of the partnered relationship, and sexual problems in the partner), and these should be considered for future interventions to address the sexual health and well-being of breast cancer survivors.

RESUMO

PURPOSE: To describe the occurrence of fatigue in a large sample of breast cancer survivors relative to general population norms and to identify demographic, medical, and psychosocial characteristics of fatigued survivors. PATIENTS AND METHODS: Breast cancer survivors in two large metropolitan areas completed standardized questionnaires as part of a survey study, including the RAND 36-item Health Survey, Center for Epidemiological Studies-Depression Scale, Breast Cancer Prevention Trial Symptom Checklist, Medical Outcomes Study Sleep Scale, and demographic and treatment-related measures. RESULTS: On average, the level of fatigue reported by the breast cancer survivors surveyed (N = 1,957) was comparable to that of age-matched women in the general population, although the breast cancer survivors were somewhat more fatigued than a more demographically similar reference group. Approximately one third of the breast cancer survivors assessed reported more severe fatigue, which was associated with significantly higher levels of depression, pain, and sleep disturbance. In addition, fatigued women were more bothered by menopausal symptoms and were somewhat more likely to have received chemotherapy (with or without radiation therapy) than nonfatigued women. In multivariate analyses, depression and pain emerged as the strongest predictors of fatigue. CONCLUSION: Although the majority of breast cancer survivors in this large and diverse sample did not experience heightened levels of fatigue relative to women in the general population, there was a subgroup of survivors who did report more severe and persistent fatigue. We identified characteristics of these women that may be helpful in elucidating the mechanisms underlying fatigue in this population, as well as directing intervention efforts.

RESUMO

Calcium-sensing by the parathyroids is abnormal in familial benign hypocalciuric hypercalcemia and in primary hyperparathyroidism (primary HPT), but the role of a calcium-sensing defect in uremic secondary hyperparathyroidism (secondary HPT) remains controversial. To study the regulation of PTH release by calcium, set point estimates were obtained using the four parameter model during in vivo dynamic tests of parathyroid gland function in 31 patients with secondary HPT, 8 patients with advanced secondary HPT studied shortly before undergoing parathyroidectomy (Pre-PTX), 3 patients with primary HPT, and 20 subjects with normal renal function (NL); the response to 2-h i.v. calcium infusions was also evaluated. Neither blood ionized calcium (iCa+2) levels nor the set point for calcium-regulated PTH release differed between secondary HPT and NL; iCa+2 levels and set point values were moderately elevated in Pre-PTX and markedly elevated in primary HPT. Compared with values obtained in NL, the lowest serum PTH levels achieved during calcium infusions, expressed as a percentage of pre-infusion values, were incrementally greater in secondary HPT, Pre-PTX, and primary HPT, whereas the slope of the relationship between iCa+2 and PTH, expressed as the natural logarithm (ln) of percent preinfusion values, decreased incrementally in secondary HPT, Pre-PTX, and primary HPT. The inhibitory effect of calcium on PTH release is blunted both in secondary HPT and primary HPT because of increases in parathyroid gland mass, but a calcium-sensing defect is a late, rather than early, consequence of renal secondary HPT.

RESUMO

Cigarette smoking is a major risk factor for head and neck cancer, and individuals who continue to smoke past diagnosis and treatment are at elevated risk for further disease. In a randomized controlled trial, a state of the art provider-delivered smoking cessation intervention was compared to a usual care advice control condition. The intervention consisted of surgeon- or dentist-delivered advice to stop smoking, a contracted quit date, tailored written materials, and booster advice sessions. Subjects were 186 patients with newly diagnosed first primary squamous cell carcinomas of the upper aerodigestive tract who had smoked cigarettes within the past year. At randomization, 88.2% of subjects were current smokers. At 12-month follow-up, 70.2% of subjects completing the trial (n = 114) were continuous abstainers; among baseline smokers alone the continuous abstinence (CA) rate was 64.6%. The cotinine validation rate at 12 months was 89.6%. Modeling techniques were utilized in order to derive expected CA rates, which included noncompleter subjects (n = 72). The CA rate expected at 1 year for the entire patient population was 64.2%, and for smokers alone the expected CA rate was 59.4%. Logistic regression analysis carried out on baseline smokers identified predictors of 12-month CA status. These included medical treatment, stage of change, age, nicotine dependence, and race. The intervention effect was not significant, although the sign of the effect was positive. Based on these findings, we recommend systematic brief advice to stop smoking for head and neck cancer patients, with a stepped care approach for patients less able to quit.

RESUMO

OBJECTIVE: This study assessed variation between neurologists in the United States and United Kingdom in their diagnostic and treatment decisions for commonly encountered neurologic presentations, and identified explanatory factors for any observed variation. METHODS: All 210 consultant neurologists in the United Kingdom and a nationally representative sample of 595 US neurologists received mailed surveys containing three detailed clinical scenarios depicting patients with (1) a single unprovoked seizure occurring 3 days previously, (2) early Parkinson's disease, and (3) dementia. The main study outcome measures were self-reported decisions regarding diagnostic test ordering and treatment, which were assessed after each scenario. Neurologists' practice characteristics, certainty about the diagnosis, and attitudes toward uncertainty were also measured. Survey response rates were 92% of US and 63% of UK neurologists. RESULTS: A higher proportion of US than UK neurologists indicated they would order additional diagnostic tests for all three scenarios (all p < 0.05); 77% of UK compared with 26% of US neurologists would manage a single unprovoked seizure without antiepileptic medication (p < 0.0001), but treatment of early Parkinson's disease was not different. Nearly all US and UK neurologists would obtain a neuroimaging study in the evaluation of dementia. International differences persisted after adjustment for differences in demographic and practice characteristics and for attitudes toward test use and clinical uncertainty. CONCLUSIONS: We identified large international variation in clinical decisions across three common neurologic conditions. Cross-country collaboration should explore these differences to develop consensus on standards of care.

RESUMO

OBJECTIVE: To compare general neurologists and MS specialists on patients' clinical characteristics and MS care as perceived by patients with MS. METHODS: We sampled all adult patients with MS having physician visits over a 2-year period from a Midwestern managed-care organization and from the fee-for-service portion of 23 randomly selected California neurologists' practices. In mid-1996, 694 subjects were mailed questionnaires; 532 (77%) responded. Sociodemographic/clinical characteristics, recent utilization of services/treatments, unmet needs, symptom care, and research participation were measured. Of 502 subjects (94%) who indicated their usual physician providing MS care was a neurologist, 217 (43%) reported having a general neurologist and 285 (57%) reported having an MS specialist. Comparisons between these two groups were adjusted for comorbidity and disease severity. RESULTS: General neurologist and MS specialist patient groups did not differ on any sociodemographic or clinical characteristic except age (p<0.05). Although health care utilization generally was similar, higher proportions of the MS specialist group were aware of or had discussed interferon beta-1b (IFNbeta-1b) with their physician (p<0.05) and were currently taking it (p<0.05); a smaller proportion of the MS specialist group reported stopping it because of side effects (p<0.01). Overall, levels of unmet need and care for recent symptoms were similar, but the MS specialist group reported more confidence in their physician/carefulness in listening (p<0.05). Twice as many MS specialist subjects had participated in nondrug research (p<0.05); drug study participation was similar. CONCLUSIONS: Patients' perceptions of their care were similar in most ways for those who designated their main MS provider as a general neurologist compared to an MS specialist; however, care differed in potentially important areas. Prospective, longitudinal studies are needed to measure and relate neurologists' training, experience, knowledge, and MS patient volume with both process and outcome measures of quality of MS care.

RESUMO

OBJECTIVE: To measure and compare care for adults with MS across managed care and fee-for-service (FFS) health systems. METHODS: The authors sampled adults with MS having physician visits over a 2-year period from a group model health maintenance organization (HMO) in southern California, from a midwestern independent practice association (IPA) model managed care plan, and from the FFS portion of the practices of a random sample of southern California neurologists. The authors mailed surveys to subjects in mid-1996; 930 of 1,164 (80%) of those eligible responded. The authors measured sociodemographic and clinical characteristics, management of recent changes in mobility, bladder control, and fatigue, use of a disease-modifying agent, assessment of general health symptoms and issues, and unmet information needs. The authors adjusted comparisons between systems for comorbidity, disease severity, and disease type. RESULTS: The groups differed on most sociodemographic and clinical characteristics. There were few differences in symptom management; differences that did exist tended toward more referrals or treatment for the FFS group. Access to the disease-modifying agent available at the time of the survey did not differ across systems, although patients' perceptions of the rationale for not using the drug did vary. General health issues and symptoms were more often assessed in the FFS and IPA systems than in the HMO, but improvement was needed across all three systems of care. There were substantial unmet information needs in all groups and especially high ones in the FFS and HMO samples. CONCLUSIONS: Strategies to improve care for people with MS should be developed and evaluated, particularly in areas like symptom assessment and meeting patient information needs. Where variations in service delivery exist, longitudinal studies are also needed to evaluate the potential impact on outcomes and to evaluate reasons for variation.

RESUMO

The relationship of various dimensions of temperament, measured by the Tridimensional Personality Questionnaire (TPQ), to polymorphisms of the D2 dopamine receptor (DRD2) and D4 dopamine receptor (DRD4) genes was determined in 119 healthy Caucasian boys who had not yet begun to consume alcohol and other drugs of abuse. Total Novelty Seeking score of the TPQ was significantly higher in boys having, in common, all three minor (A1, B1, and Intron 6 1) alleles of the DRD2 compared to boys without any of these alleles. Boys with the DRD4 7 repeat (7R) allele also had a significantly higher Novelty Seeking score than those without this allele. However, the greatest difference in Novelty Seeking score was found when boys having all three minor DRD2 alleles and the DRD4 7R allele were contrasted to those without any of these alleles. Neither the DRD2 nor the DRD4 polymorphisms differentiated total Harm Avoidance score. Whereas subjects having all three minor DRD2 alleles had a significantly higher Reward Dependence 2 (Persistence) score than subjects without any of these alleles, no significant difference in this personality score was found between subjects with and without the DRD4 7R allele. In conclusion, DRD2 and DRD4 polymorphisms individually associate with Novelty Seeking behavior. However, the combined DRD2 and DRD4 polymorphisms contribute more markedly to this behavior than when these two gene polymorphisms are individually considered.

RESUMO

BACKGROUND: Patients with inflammatory bowel disease (IBD) have a high prevalence of osteoporosis. A number of studies have found that corticosteroid use is associated with the development of osteoporosis in these patients. Calcium supplementation may be of benefit in corticosteroid-induced osteoporosis and calcium may be a nutrient that patients with IBD lack. AIM: To test the benefit of calcium supplementation on bone density in a pilot study over a 1-year period, in a group of corticosteroid-using patients with IBD, in a randomized, double-blind, placebo-controlled treatment study. METHODS: Corticosteroid-using patients with IBD including males over the age of 18 years and premenopausal females, were randomized to receive either calcium carbonate 1000 mg plus vitamin D 250 IU (Oscal) or an identically matched placebo. Dual energy X-ray absorptiometry measurements of bone density were obtained at entry and at 1 year. At entry, and every 3 months thereafter, serum was collected for the measurement of haemoglobin, biochemistry and bone hormones. Simultaneously a 24-h urine collection was analysed for calcium excretion and creatinine clearance, and a 4-day food record was collected to document dietary calcium and vitamin D ingestion. RESULTS: We found a high prevalence of moderately severe decreased bone density in corticosteroid-using patients with IBD. The dose of prednisone in the year prior to study entry was inversely correlated with bone density at the hip (R = -0.67, P = 0.004). At study entry serum osteocalcin was inversely correlated with corticosteroid dose in the year prior to the study (R = -0.64, P = 0.02) and at study end, directly correlated with the percentage change in spine bone density (R = 0.59, P = 0.01). The dietary calcium intake of these patients was close to the current RDA (recommended daily intake) for premenopausal, post-adolescent adults. Calcium supplementation with small extra doses of vitamin D conferred no obvious benefit to bone density at the end of 1 year. There was no correlation between oral calcium ingestion and bone mass measurements. Both the treatment and placebo groups' bone density remained relatively stable at 1 year, suggesting that bone loss in corticosteroid-using patients may peak early into the use of the corticosteroids. CONCLUSIONS: Calcium supplementation (1000 mg/day) conferred no significant benefit to bone density at 1 year in patients with corticosteroid-using IBD patients with osteoporosis. Future investigations should explore other therapeutic avenues that may have greater effects on increasing bone density in patients who already have considerable osteoporosis.

RESUMO

OBJECTIVE: To examine treatment for depression among older adults in a large staff model health maintenance organization (HMO). DESIGN: A 4-year prospective cohort study (1989-1993). SETTING: Four primary care clinics of a large staff model HMO in Seattle, Washington. PATIENTS: A total of 2558 Medicare enrollees aged 65 and older. MAIN OUTCOME MEASURES: Treatment of depression was defined as primary care visits resulting in depression diagnoses, use of antidepressant medications, or specialty mental health services. MAIN RESULTS: The older adults in our sample had low rates of treatment for depression, ranging from 4 to 7% in the entire sample and from 12 to 25% among those with probable depressive disorders. Predictors of treatment included female gender, severity, and persistence of depressive symptoms, and severity of comorbid medical illness. Even when patients were treated for depression, the intensity of treatment was very low. Overall likelihood of treatment for depression increased somewhat from 1989 to 1993, but among those treated, the rate of adequate antidepressant use remained below 30%. CONCLUSIONS: There is still considerable need to improve care for older adults with depression in primary care.

RESUMO

OBJECTIVE: To examine variation in patient characteristics (case-mix) and treatment patterns for attention-deficit/hyperactivity disorder (ADHD) by provider type. METHOD: By means of a two-stage study design, 102 children were identified as receiving treatment for ADHD in the past year, among a school district-wide sample of second-through fourth-grade special education students. Parent and child interviews were conducted using standardized measures of need for treatment, service use, and process of care. RESULTS: Nearly three fourths of the children received treatment for ADHD by a primary care provider, and of these, 68% did not have any contact with a mental health specialist. Children treated only by a primary care provider had fewer comorbid conditions, less impairment, and lower levels of family burden than children treated only by a mental health specialist. Treatment of ADHD solely by primary care providers was characterized by fewer sessions, less time with the patient, and less use of multimodal therapies. CONCLUSION: Future studies examining clinical outcomes for ADHD treatment should take into account variation in case-mix and treatment patterns by provider type.

RESUMO

OBJECTIVE: To examine the diagnostic utility of two commonly used attention-deficit hyperactivity disorder (ADHD) screening measures in a population of special education students and address whether screener performance is affected by demographic characteristics. METHOD: A school district population of special education students was screened for ADHD risk using two parent questionnaires, the 46-item Attention Deficit Disorders Evaluation Scale (ADDES) and the 10-item Conners Abbreviated Symptom Questionnaire (ASQ). All high-risk children and a random sample of low-risk children subsequently underwent DSM-IV-based diagnostic assessment through parental diagnostic interviews (Diagnostic Interview Schedule for Children Version 3.0). Diagnostic utility was summarized by sensitivity, specificity, predictive utilities of positive and negative tests, and efficiency, all of which were estimated using an approach that accounted for the sampling design. RESULTS: Overall efficiency scores ranged between 70% and 74%. Sensitivity estimates were below 70% even at low screener cutoff scores. The ADDES did not perform significantly better than the ASQ. Significant gender and ethnicity effects emerged. CONCLUSIONS: Overall, both the ASQ and the ADDES yielded substantial numbers of false positives and false negatives among this population of children, indicating that alternative approaches will be required to accurately and efficiently identify children in need of services for ADHD. Child psychiatrists can play a valuable consulting role as school districts and primary care settings struggle to implement appropriate identification procedures for ADHD.

RESUMO

Following a suicide attempt by female adolescents, the impact of a specialized emergency room (ER) care intervention was evaluated over the subsequent 18 months. Using a quasi-experimental design, this study assigned 140 female adolescent suicide attempters (SA), ages 12-18 years, and their mothers (88% Hispanic) to receive during their ER visit either: (a) specialized ER care aimed at enhancing adherence to outpatient therapy by providing a soap opera video regarding suicidality, a family therapy session, and staff training; or (b) standard ER care. The adjustment of the SA and their mothers was evaluated over 18 months (follow-up, 92%) using linear mixed model regression analyses. SA's adjustment improved over time on most mental health indices. Rates of suicide reattempts (12.4%) and suicidal reideation (29.8%) were lower than anticipated and similar across ER conditions. The specialized ER care condition was associated with significantly lower depression scores by the SA and lower maternal ratings on family cohesion. Significant interactions of intervention condition with the SA's initial level of psychiatric symptomatology indicated that the intervention's impact was greatest on maternal emotional distress and family cohesion among SA who were highly symptomatic. SA's attendance at therapy sessions following the ER visit was significantly associated with only one outcome--family adaptability. Specialized ER interventions may have substantial and sustained impact over time, particularly for the parents of youth with high psychiatric symptomatology.

RESUMO

This study describes the level of psychotropic medication use and patterns of such treatment among school-aged children in foster care. Structured survey interviews were conducted in the foster homes of 302 randomly selected children, aged 6-12 years, who were living in foster care for 6 months or more and placed from three county service areas. Follow-up mental health assessments using the existing system of care format were completed on 255 children. Sixteen percent of these school-aged children in foster care were found to have taken psychotropic medication during their lifetime. The most common class of medication used in the past year was stimulants (62%). Children who were older, from Caucasian and biracial backgrounds, and who lived in a group home more likely to have taken psychotropic medication in the past year. Among those children who received a clinician diagnosis of a severe psychiatric disorder for which medication is an accepted component of care, boys were more likely to receive medication treatment than girls. Sociodemographic characteristics and placement history variables may be influential in the level of psychotropic medication use among this population. Further research to examine the appropriateness and level of benefit of medication treatment in this population is needed.

RESUMO

A meta-analysis was carried out to evaluate data published between January 1974 and February 1998 comparing rates of treatment response and tolerability of pharmacological and psychological treatments for depression in persons over age 55. Drugs (tricyclic antidepressants, selective serotonin-reuptake inhibitors, and a mixed group of other drugs) were significantly better than placebo, with an average reduction in symptom severity of 48.0% versus 31.3% (analysis weighted by sample size; 50.6% vs. 21.4% unweighted). No single drug or group of drugs was superior in terms of efficacy, and no statistically significant differences in tolerability emerged between tricyclic antidepressants and selective serotonin-reuptake inhibitors, whether measured by total dropouts or by dropouts due to side effects. Compared to the data on pharmacological treatments, those for outcomes of psychological treatments are very limited. Existing data indicate that cognitive-behavioral, behavioral, and psychodynamic therapies are significantly better than placebo. In the current meta-analysis, response rates to these nondrug therapies did not differ significantly from those observed with tricyclic antidepressants or selective serotonin-reuptake inhibitors, but direct comparison data are insufficient for firm conclusions to be drawn about comparative efficacy. It is possible, even likely, that not only different subtypes of depression but also different patients vary in their treatment responses. However, lack of adequate data prevented the current meta-analysis from addressing these issues. Rigorously designed prospective studies on treatment outcome, taking into account the above differences, are urgently needed to provide robust data on which to base clinical recommendations for the treatment of depression in older patients.

RESUMO

Access to treatment for children with attention-deficit hyperactivity disorder (ADHD) was examined in the general health, specialty mental health, and informal care sectors. Special education students in a Florida school district were screened for ADHD, and high-risk children and their parents completed diagnostic and services assessment interviews. Female gender, minority status, and rural residence lowered the probability of ADHD service use in the general health sector. Use of services in the mental health and informal sectors was predicted by a child's need for services. Further study is needed to identify barriers to service use at the parental or gatekeeper level for this common disorder among children.
