Mobility and dementia: is physiotherapy treatment during respite care effective?

BACKGROUND: Mobility problems experienced by elderly people with a dementia are associated with falls, fractures and admission to long-term care. A hospital respite care admission is therefore often seen as an opportunity to provide physiotherapy treatment. AIM: To find whether elderly people with a dementia and a mobility problem show a greater improvement in mobility skills if given physiotherapy treatment than if given non-physical activities intervention during a hospital respite admission. METHOD: A controlled randomized multicentre trial with independent blinded assessment. The Southampton Mobility Assessment (mobility score) and Two Minute Walking Test (distance walked) were undertaken at the beginning and end of the study admission and beginning of the next respite admission. Following the first assessment, participants were randomized to either physiotherapy or activities. RESULTS: Eighty-one participants, from 12 clinical centres, with a mean age of 81.9 years and CAPE I/O score of 2. During the study admission there was a non-significant trend for a lower reduction in mobility score of the physiotherapy group (Mann-Whitney; p = 0.614) and a non-significant trend for greater decrease in distance walked in the activities group (t-test; p = 0.325). DISCUSSION: The results of this trial do not support the positive changes demonstrated elsewhere. However, changes in respite care during the early stages of this trial may have produced differences between the sample for this trial and that for the pilot study. This trial was therefore underpowered. CONCLUSION: This trial suggests that future research needs to change the focus from clinical settings to presentations.

Integrative review of physical activity intervention research with aging adults.

This paper reviews randomized, controlled trials (RCTs) that have attempted to increase physical activity behavior by aging adults. A systematic review was necessary because numerous studies target older adults, and previous reviews have addressed a limited range of primary studies. Computerized database, ancestry, and extensive search strategies by authors of research reported in English between 1960 and 2000 located diverse intervention trials. RCTs reporting endurance physical activity or exercise behavioral outcomes for at least five subjects were included. Integrative review methods were used to summarize extant research. Forty-two studies were retrieved. Seventeen RCTs with 6,391 subjects were reviewed. A wide variety of intervention strategies were reported. The most common interventions were self-monitoring, general health education, goal setting, supervised center-based exercise, problem solving, feedback, reinforcement, and relapse prevention education. Few studies individually adapted motivational interventions, used mediated intervention delivery, or integrated multiple theoretical frameworks into the intervention. Links between individual intervention components and effectiveness were not clear. Common methodological weaknesses included small samples, untested outcome measures, and time-limited longitudinal designs. Significant numbers of aging adults increased their physical activity in response to experimental interventions. The amount of increased activity rarely equaled accepted behavior standards to achieve positive health outcomes. Further work is essential to identify successful strategies to increase activity by larger numbers of elders and to accelerate the increase in activity by those who change activity behaviors. Sex and ethnic differences need further investigation. There is a vital need for rigorously designed studies to contribute to this science.

Hemorrhagic vasculopathy after treatment of central nervous system neoplasia in childhood: diagnosis and follow-up.

PURPOSE: To review the clinical data, imaging findings, and intermediate outcomes of a series of children with hemorrhagic vasculopathy after treatment for intracranial neoplasia. METHODS: We retrospectively analyzed the medical records and imaging examinations of 20 pediatric patients (ages 1 to 15 years) with intracranial neoplasia in whom delayed intracranial hemorrhage developed after cranial irradiation or radiation combined with systemic or intrathecal chemotherapy. Patients with intracranial hemorrhage from other identifiable causes were excluded. Histopathologic analysis was available in four patients. RESULTS: Twenty patients with delayed intracranial hemorrhage received cranial irradiation alone (n = 9) or combined radiation and chemotherapy (n = 11) for primary brain tumors (n = 13), leukemia (n = 6), or lymphoma (n = 1). Imaging findings were consistent with hemorrhages of varying ages. The hemorrhages were not associated with tumor recurrence nor second tumors. Except for location of the hemorrhage, no significant relationship was established between outcome and original diagnosis, radiation dose (range, 1800 to 6000 centigray), chemotherapeutic agent or dosage, age at treatment, or interval between therapy and hemorrhage (mean, 8.1 years). Only brain stem hemorrhage was associated with a poor outcome. CONCLUSION: In children with central nervous system neoplasia who have undergone cranial irradiation, or radiation combined with chemotherapy, delayed intracranial hemorrhage may develop.

T-lymphocyte subsets in patients with abnormal body weight: longitudinal studies. in anorexia nervosa and obesity.

OBJECTIVE: In contrast to other types of starvation which are characterized by low CD4+ counts and increased susceptibility to infection, anorexia nervosa is not associated with an increase in infectious complications. To determine why infection risk of anorectics differs from that of other starving populations, we studied T-lymphocytes, including CD4+ and CD8+ phenotypes, in patients with anorexia nervosa, and for comparison, in dieting obese subjects. METHODS: T-lymphocyte phenotypes were determined by flow cytometric analysis of monoclonal antibody-labeled cells obtained from patients with anorexia nervosa before and after successful therapy and weight gain, and in obese subjects before and after weight loss on a very-low-calorie diet. RESULTS: Weight loss in anorectics and obese dieters was associated with normal CD4+ counts. Unexpectedly, CD8+ counts were low in anorectics, both before and after weight gain, and in obese subjects after (but not before) dieting. DISCUSSION: Normal CD4+ counts in anorectics and obese dieters, despite marked weight loss, may explain the lack of increased infection risk in these eating-disordered patients, in contrast to other starving populations. The observation that CD8+ counts are low in anorectics with low and restored body weight and in obese patients after dieting has not been previously reported. The persistence of low CD8+ counts in anorectics even after weight gain suggests that some factors other than weight loss per se may be involved, possibly including effects due to stress, comorbid psychiatric conditions, or unidentified aspects of dysregulated pathophysiology secondary to disordered eating.

Positioning for stroke patients: a survey of physiotherapists' aims and practices.

PURPOSE: The survey was undertaken to identify current physiotherapy practice for positioning patients in the first week following stroke. METHOD: A postal questionnaire comprised of closed questions, was sent to 674 physiotherapists identified as working with patients in the first week following stroke, who were employed in 155 randomly selected NHS Trusts throughout England. RESULTS: Response rate was 73%. Specific positions were recommended during the first week following stroke by 98 % of respondents. The most common aims of positioning were modulation of muscle tone (93%), preventing damage to affected limbs (92%) and supporting and stabilizing body segments (91%). The positions sitting in an armchair, side lying on the non-hemiplegic side and side lying on the hemiplegic side were recommended by 98%, 96% and 92% of respondents respectively. The components of the positions considered as 'most important' varied between positions, proximal components were usually preferred to distal components. CONCLUSION: Positioning is still an important part of physiotherapy practice and therefore requires evaluation. The positions used and the aims of positioning identified by clinicians accord with those in the literature. However, there is a lack of consensus regarding key components of the positions. The positions identified in this study should now be systematically evaluated for their ability to achieve different aims.

Cytokine production in patients with anorexia nervosa, bulimia nervosa, and obesity.

OBJECTIVE: We previously reported elevated serum levels of the cytokines interleukin-6 (IL-6) and transforming growth factor-beta (TGF-beta) in patients with anorexia nervosa (AN). We investigated the cellular production of these two cytokines and of interferon-gamma (IFN-gamma), interleukin-1alpha (IL-1alpha), and tumor necrosis factor-alpha (TNF-alpha) in subjects with AN, bulimia nervosa (BN), and obesity as well as in normal-weight control subjects. METHODS: Supernatant fluids from isolated peripheral blood mononuclear cells (PBMC) incubated with and without concanavalin A (ConA) were assayed for cytokine concentrations by enzyme-linked immunosorbent assay (ELISA). RESULTS: Significant differences across the four groups were found in the stimulated cellular production of IFN-gamma and IL-6. Stimulated IFN-gamma production was elevated in the AN group compared to controls. IL-6 production was significantly elevated in obese subjects relative to the two normal-weight groups, BN and controls, and tended to be higher in the AN group than in the controls, but not significantly so. IL-1alpha production was greater in obese subjects. CONCLUSION: The findings of increased IFN-gamma production and a tendency toward increased IL-6 production (both of which suppress food intake in animals) in individuals who severely restrict food intake suggest a potential role for these cytokines in the pathogenesis of AN. Elevated IL-6 and IL-1alpha production by PBMC in obese individuals requires further investigation to determine if these cytokines contribute to the development or perpetuation of obesity.

Motor imagery: a backdoor to the motor system after stroke?

BACKGROUND AND PURPOSE: Understanding brain plasticity after stroke is important in developing rehabilitation strategies. Active movement therapies show considerable promise but depend on motor performance, excluding many otherwise eligible patients. Motor imagery is widely used in sport to improve performance, which raises the possibility of applying it both as a rehabilitation method and to access the motor network independently of recovery. Specifically, whether the primary motor cortex (M1), considered a prime target of poststroke rehabilitation, is involved in motor imagery is unresolved. SUMMARY OF REVIEW: We review methodological considerations when applying motor imagery to healthy subjects and in patients with stroke, which may disrupt the motor imagery network. We then review firstly the motor imagery training literature focusing on upper-limb recovery, and secondly the functional imaging literature in healthy subjects and in patients with stroke. CONCLUSIONS: The review highlights the difficulty in addressing cognitive screening and compliance in motor imagery studies, particularly with regards to patients with stroke. Despite this, the literature suggests the encouraging effect of motor imagery training on motor recovery after stroke. Based on the available literature in healthy volunteers, robust activation of the nonprimary motor structures, but only weak and inconsistent activation of M1, occurs during motor imagery. In patients with stroke, the cortical activation patterns are essentially unexplored as is the underlying mechanism of motor imagery training. Provided appropriate methodology is implemented, motor imagery may provide a valuable tool to access the motor network and improve outcome after stroke.

Immunogenicity of three Haemophilus influenzae type b protein conjugate vaccines in HIV seropositive adults and analysis of predictors of vaccine response.

HIV-seropositive adults may be at increased risk of infection due to Haemophilus influenzae type b (Hib) as compared with HIV-seronegative adults. Protein conjugate vaccines have been demonstrated to induce protective levels of antibodies against Hib in immunocompetent infants and also in HIV-seropositive infants. In this study we determined the immunogenicity of three protein conjugate Hib vaccines (PRP-D, HbOC, HbNOMP) in 135 HIV-seropositive adults who received one dose of Hib vaccine. Anti-polyribosylribitol phosphate (PRP) antibodies were measured at 0, 1, 3 and 12 months postimmunization by the Farr method. We demonstrate that all three vaccines are highly immunogenic and result in protective (> 1.0 microg/ml) levels of antibody. Overall the anti-PRP antibody level was > 1.0 microg/ml in 26% of patients preimmunization, 91% at both 1 and 3 months, and 79% at 12 months postvaccination. Comparison of responses to the three vaccines over time demonstrated differences in the mean geometric anti-PRP antibody level at 1 month (p=0.03) and the 12 month time points (p=0.03) with lower geometric mean levels in the HbNOMP group, though baseline differences in groups limit the interpretation of these findings. In a univariate analysis of baseline characteristics which predicted poor vaccine response, low total IgG2 levels preimmunization predicted a poor antibody response at 1 month (p < 0.01) and at 12 months (p=0.05), while low CD4 T-cell count predicted poor response at 12 months (p < 0.01). We conclude that all three US licensed protein conjugate Hib vaccines are immunogenic in HIV-seropositive adults, and that baseline CD4 T-cell count and IgG2 levels predict the likelihood of antibody response to vaccine.

Neurological dysfunction associated with postoperative cerebellar mutism.

BACKGROUND AND OBJECTIVES: The postoperative cerebellar mutism syndrome (CMS) is an unique acute postoperative complication characterized by transient decrease in speech output (often mutism), apathy, irritability as well as global cerebellar dysfunction. As much as 25% of patients undergoing a resection of a cerebellar or IV ventricular tumor may develop such a syndrome. In this retrospective study we characterize the clinical features of the CMS and explore potential etiologic mechanisms. METHODS: We conducted a retrospective analysis of medical records and imaging tests of 8 consecutive patients with the CMS identified through the database of the Children's Hospital and Dana-Farber Cancer Institute, Boston, and compared with a control group of 8 unaffected children undergoing a comparable tumor resection. RESULTS: In contrast to the control group, children in the affected group had marked decrease in speech output and comprehension, apathy and lack of initiative, inattention, persistent eye closure, flaccid hemiparesis and a severe global cerebellar dysfunction. Swallowing difficulties and bowel and bladder dysfunction were also observed. The median duration of the syndrome as judged by the persistence of the communication abnormalities was 4 weeks. The recovery was near complete with exception for a persistent global cerebellar dysfunction. A comparison of CT and MRI scans of children in both groups failed to identify distinguishing features. CONCLUSION: A surgical lesion of the midline cerebellum can cause a complex neurological dysfunction such as the CMS. Thus, we postulate that the cerebellum and its connections function as a 'modulatory system' in control of both motor and non-motor functions, including attention and language.

Escalated dose for non-small-cell lung cancer with accelerated hypofractionated three-dimensional conformal radiation therapy.

BACKGROUND AND PURPOSE: To prospectively assess the feasibility and efficacy of a hypofractionated accelerated radiotherapy regimen (72 Gy in 24 daily fractions, 3 Gy per fraction) in patients (pts) with non-resectable non-small-cell lung cancer (NSCLC). MATERIAL AND METHODS: We included 25 pts with a histologically or cytologically proven NSCLC, with KPS > or = 70 and < or =10% weight loss over prior three months, and with tumour stage I/II medically inoperable (9 pts) or non-resectable stage III a/b without pleural effusion (16 pts). Eleven pts received induction chemotherapy. No more than 30% of the combined lung volume could receive more than 25 Gy and the maximal biological effective dose to the spinal cord was maintained below 44 Gy. RESULTS: No grade-4 acute toxicity event was reported. Two pts had a treatment break because of grade-3 acute oesophagitis. Twenty-two pts were evaluable for long-term toxicity (median follow-up=9.7 months, range 4 to 30.2 months). There were 4 Grade-1 pulmonary and 2 Grade-1 oesophageal long-term toxicity events. Twenty-two pts were evaluable for tumour response with 7 complete and 8 partial responses, 5 stable diseases and 2 progressive diseases. The actuarial 1-year overall and thoracic-progression-free survival rates were 68% and 72% respectively. CONCLUSIONS: This study demonstrates the feasibility of the experimental radiotherapy schedule, however more data are needed to confirm its efficacy.

Demyelinated neocortical lesions in marmoset autoimmune encephalomyelitis mimic those in multiple sclerosis.

The use of immunohistochemical methods has led to a new understanding of the prevalence and significance of cortical lesions in multiple sclerosis but these lesions have not yet been formally described in an animal model. In this study we have set out to use immunohistochemical techniques to identify and describe cortical lesions in marmosets with experimental autoimmune encephalomyelitis (EAE). Using antibodies to proteolipid protein (PLP), we found a total of 70 cortical lesions in 11 tissue blocks from 6 animals. These lesions were subdivided into leucocortical (40), intracortical (12) and subpial lesions (18). We quantified the density of inflammatory cells within lesions using a double labelling protocol which employed anti-PLP in addition to antibodies against markers of B-lymphocytes (CD20), T-lymphocytes (CD3), macrophages (MAC387) and MHC-II expressing cells (CR3/43). This analysis revealed that the large subpial lesions accounted for the majority of demyelinated cortex (88%) despite possessing the lowest density of inflammatory cells. This study has shown that lesions in this model share many of the major features of cortical lesions in multiple sclerosis both in terms of morphology and inflammatory cell content. We believe that this tool can be exploited in future studies to investigate the aetiology, development and clinical significance of cortical lesions in demyelinating disease.

MR imaging-guided focused ultrasound surgery of fibroadenomas in the breast: a feasibility study.

PURPOSE: To test the feasibility of noninvasive magnetic resonance (MR) imaging-guided focused ultrasound surgery (FUS) of benign fibroadenomas in the breast. MATERIALS AND METHODS: Eleven fibroadenomas in nine patients under local anesthesia were treated with MR imaging-guided FUS. Based on a T2-weighted definition of target volumes, sequential sonications were delivered to treat the entire target. Temperature-sensitive phase-difference-based MR imaging was performed during each sonication to monitor focus localization and tissue temperature changes. After the procedure, T2-weighted and contrast material-enhanced T1-weighted MR imaging were performed to evaluate immediate and long-term effects. RESULTS: Thermal imaging sequences were improved over the treatment period, with 82% (279 of 342) of the hot spots visible in the last seven treatments. The MR imager was used to measure temperature elevation (12.8 degrees -49.9 degrees C) from these treatments. Eight of the 11 lesions treated demonstrated complete or partial lack of contrast material uptake on posttherapy T1-weighted images. Three lesions showed no marked decrease of contrast material uptake. This lack of effective treatment was most likely due to a lower acoustic power and/or patient movement that caused misregistration. No adverse effects were detected, except for one case of transient edema in the pectoralis muscle 2 days after therapy. CONCLUSION: MR imaging-guided FUS can be performed to noninvasively coagulate benign breast fibroadenomas.

Neuropsychological functioning after surgery in children treated for brain tumor.

OBJECTIVE: To describe the neuropsychological functioning of children treated with surgery only for localized brain tumors in Dana-Farber Cancer Institute Protocol 92-077. Subsequent reports will describe the neuropsychological functioning of children treated with surgery and stereotactic radiation therapy on Dana-Farber Cancer Institute 92-077. METHODS: The intellectual functioning of 106 patients was evaluated within 3 months after surgery. An in-depth assessment of the neuropsychological functioning, including an impairment index, was conducted for a subset of 77 school-age children (6-16 yr old) across six functional domains. Descriptive statistics were generated; binomial distribution analyses were performed to assess whether the proportion of individuals with impaired performance on each measure exceeded normative expectations. The impairment index assessed whether poor performance was attributable to a few children or reflected the performance of the cohort as a whole. RESULTS: Although the Full Scale IQ was within normative expectations, the Verbal IQ was higher than the Performance IQ with 45% of individuals showing a significant discrepancy (P < 0.01) between these scales. There was an increased prevalence of poor performance for measures of motor output, verbal memory, and visuospatial organization. The distribution of the impairment index indicated moderate impairment across the school-age cohort rather than severe impairment in a few patients. CONCLUSION: The results document a moderate level of neuropsychological morbidity among children with brain tumors before stereotactic radiation therapy, presumably referable to the tumor itself and the surgery. The extent to which stereotactic radiation therapy may increase this burden will be assessed in follow-up studies evaluating the longitudinal neuropsychological data.

Psychiatric symptoms in preschool children with PDD and clinic and comparison samples.

OBJECTIVE: This study describes and compares the severity of DSM-IV symptoms in preschool children with diagnosed pervasive developmental disorder (PDD), clinic controls, and two community-based samples. METHOD: Parents (/and teachers) completed the early child inventory-4 (ECI-4), a DSM-IV-referenced rating scale for four samples: PDD (n = 172/160) and nonPDD psychiatric clinic referrals (n=135/101) and youngsters in regular (n=507/407) and special (n =64/140) early childhood programs. Children ranged in age from 3 to 5 years old. RESULTS: With the exception of conduct problems, the PDD group generally received higher symptom severity ratings than the regular early childhood group, but the pattern of differences compared with the other two groups often varied by type of symptom and informant. Teachers rated the PDD and nonPDD clinic groups as having equally severe ADHD and oppositional defiant disorder symptoms. Teachers rated the PDD group as having more severe anxiety and depression symptoms than parents. The Asperger group was rated by both informants as more oppositional than the autism and PDDNOS subgroups. Teachers rated males in the regular early childhood sample as having more severe ADHD and aggressive symptoms than females, but this was not the case for the PDD sample. CONCLUSION: Preschoolers with PDD exhibit more severe DSM-IV psychiatric symptoms than children in regular and special early childhood programs, and to some extent nonPDD psychiatric referrals. The concept of comorbidity warrants further exploration, as does informant-specific syndromes as validators of diagnostic constructs.

Combination chemotherapy in refractory immune thrombocytopenic purpura.

BACKGROUND: Chronic idiopathic thrombocytopenic purpura is a destructive thrombocytopenia caused by an autoantibody. About 80 percent of patients with chronic idiopathic thrombocytopenic purpura have remissions after either corticosteroid therapy or splenectomy. Some patients with resistant disease respond to other agents, but a substantial group are refractory to therapy. METHODS: We used combination chemotherapy to treat 10 patients with refractory immune thrombocytopenia. An average of 6.8 (range, 3 to 10) previous therapies, including corticosteroids and splenectomy, had been unsuccessful in these patients. The patients received from three to eight cycles of therapy consisting of cyclophosphamide and prednisone combined with either vincristine (one patient), vincristine and procarbazine (four patients), or etoposide (six patients, including one patient who received four cycles each containing procarbazine and etoposide). RESULTS: Among the 10 patients, 6 had complete responses (platelet count, > 180,000 per cubic millimeter); of these, 4 patients had responses that persisted for more than 11, 30, 54, or 126 months, 1 had a relapse 9 months after therapy but had a remission with further therapy and remained in remission for 48 months before dying of an unrelated illness, and another relapsed just before her fifth course of therapy. Two patients had partial responses (platelet count, > 50,000 per cubic millimeter); the platelet counts in one remained stable for more than nine months after the end of therapy, and the other patient relapsed. The remaining two patients had no response. Complete responses were associated with a disappearance or marked decrease in the level of platelet-associated autoantibody. CONCLUSIONS: Combination chemotherapy is beneficial in some patients in whom immune thrombocytopenia is refractory to corticosteroids and splenectomy.

Medulloblastoma outcome is adversely associated with overexpression of EEF1D, RPL30, and RPS20 on the long arm of chromosome 8.

BACKGROUND: Medulloblastoma is the most common malignant brain tumor of childhood. Improvements in clinical outcome require a better understanding of the genetic alterations to identify clinically significant biological factors and to stratify patients accordingly. In the present study, we applied cytogenetic characterization to guide the identification of biologically significant genes from gene expression microarray profiles of medulloblastoma. METHODS: We analyzed 71 primary medulloblastomas for chromosomal copy number aberrations (CNAs) using comparative genomic hybridization (CGH). Among 64 tumors that we previously analyzed by gene expression microarrays, 27 were included in our CGH series. We analyzed clinical outcome with respect to CNAs and microarray results. We filtered microarray data using specific CNAs to detect differentially expressed candidate genes associated with survival. RESULTS: The most frequent lesions detected in our series involved chromosome 17; loss of 16q, 10q, or 8p; and gain of 7q or 2p. Recurrent amplifications at 2p23-p24, 2q14, 7q34, and 12p13 were also observed. Gain of 8q is associated with worse overall survival (p = 0.0141), which is not entirely attributable to MYC amplification or overexpression. By applying CGH results to gene expression analysis of medulloblastoma, we identified three 8q-mapped genes that are associated with overall survival in the larger group of 64 patients (p < 0.05): eukaryotic translation elongation factor 1D (EEF1D), ribosomal protein L30 (RPL30), and ribosomal protein S20 (RPS20). CONCLUSION: The complementary use of CGH and expression profiles can facilitate the identification of clinically significant candidate genes involved in medulloblastoma growth. We demonstrate that gain of 8q and expression levels of three 8q-mapped candidate genes (EEF1D, RPL30, RPS20) are associated with adverse outcome in medulloblastoma.

Critical thinking in graduate medical education: A role for concept mapping assessment?

CONTEXT: Tools to assess the evolving conceptual framework of physicians-in-training are limited, despite their critical importance to physicians' evolving clinical expertise. Concept mapping assessment (CMA) enables teachers to view students' organization of their knowledge at various points in training. OBJECTIVE: To assess whether CMA reflects expected differences and changes in the conceptual framework of resident physicians, whether concept maps can be scored reliably, and how well CMA scores relate to the results of standard in-training examination. DESIGN, SETTING, AND PARTICIPANTS: A group of 21 resident physicians (9 first-year and 12 second- and third-year residents) from a university-based pediatric training program underwent concept map training, drew a preinstruction concept map about seizures, completed an education course on seizures, and then drew a postinstruction map. Maps were scored independently by 3 raters using a standardized method. The study was conducted in May and June 1999. MAIN OUTCOME MEASURES: Preinstruction map total scores and subscores in 4 categories compared with postinstruction map scores; map scores of second- and third-year residents compared with first-year residents; and interrater correlation of map scores. RESULTS: Total CMA scores increased after instruction from a mean (SD) preinstruction map score of 429 (119) to a mean postinstruction map score of 516 (196) (P =.03). Second- and third-year residents scored significantly higher than first-year residents before instruction (mean [SD] score of 472 [116] vs 371 [102], respectively; P =.04), but not after instruction (mean [SD] scores, 561 [203] vs 456 [179], respectively; P =.16). Second- and third-year residents had greater preinstruction map complexity as measured by cross-link score (P =.01) than first-year residents. The CMA score had a weak to no correlation with the American Board of Pediatrics In-training Examination score (r = 0.10-0.54). Interrater correlation of map scoring ranged from weak to moderate for the preinstruction map (r = 0.51-0.69) and moderate to strong for the postinstruction map (r = 0.74-0.88). CONCLUSIONS: Our data provide preliminary evidence that concept mapping assessment reflects expected differences and change in the conceptual framework of resident physicians. Concept mapping assessment and standardized testing may measure different cognitive domains. JAMA. 2000;284:1105-1110

Low-income minority women at risk for cervical cancer: a process to improve adherence to follow-up recommendations.

OBJECTIVE: The Houston Department of Health and Human Services (HDHHS) has a centralized process for notifying and setting up follow-up appointments for women with abnormal Pap smears who are clients of HDHHS health centers. Faculty and a student from the University of Texas School of Public Health and HDHHS personnel jointly conducted a study to evaluate the process and performance of the system. METHODS: The study examined two subpopulations: women with atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesions (ASCUS/LGSIL) and women with high-grade squamous intraepithelial lesions or atypical glandular cells of undetermined significance (HGSIL/AGCUS). A retrospective study was conducted of data on women attending eight HDHHS clinics during the period from February 1996 through August 2000. Records of 1,216 women referred for evaluation of abnormal Pap smears were reviewed. Process effectiveness was measured by the number of successful contacts made and the number of appointments set up. Performance was measured by compliance with referral appointments. Predictors included race/ethnicity, age, co-existence of a sexually transmitted disease, number of prior referrals, type of patient visit, and health center attended. RESULTS: HDHHS staff successfully notified 95.6% of women with ASCUS/LGSIL and 97.9% of women with HGSIL/AGCUS. Using performance criteria as outcome measures, high-risk women requiring targeted interventions were identified. Overall, 84.2% of women scheduled appointments. Among those with ASCUS/LGSIL, women identified as African American were 53% less likely to accept an appointment and 45% less likely to show up for the appointment than those identified as Hispanic or "other." Age and type of patient visit appeared to be significantly associated with patient compliance behavior. CONCLUSION: The study describes the effectiveness of a centralized patient follow-up process for women at risk for cervical cancer.
