Abstract
OBJECTIVE This study examined the cross-sectional and longitudinal relationships of built environment characteristics with adiposity and glycaemic measures. METHOD Longitudinal study sample consisted of 4,010 Framingham Heart Study Offspring (baseline: 1998-2001; follow-up: 2005-2008) and Generation Three (baseline: 2002-2005; follow-up: 2008-2011) participants (54.8% women, baseline mean age 48.6 years). Built environment characteristics (intersection density, greenspace, recreation land and food stores) at baseline were collected. Adiposity and glycaemic measures (body mass index [BMI], waist circumference, abdominal subcutaneous and visceral adipose tissue, and fasting plasma glucose) at baseline and changes during 6.4-year follow-up were measured. RESULTS In cross-sectional models, higher intersection density and food store density (total food stores, fast food restaurants and supermarkets) were linearly associated with higher BMI (all p < 0.05). Higher greenspace was associated with lower BMI, waist circumference, fasting plasma glucose, prevalent obesity and prevalent diabetes (all p < 0.05). Longitudinally, higher intersection density and food store density, and lower greenspace were associated with smaller increases in abdominal visceral adipose tissue (all p < 0.05). Higher densities of intersections, fast food restaurants and supermarkets were associated with smaller increases in fasting plasma glucose (all p < 0.05). CONCLUSIONS Collectively, built environment characteristics are associated with adiposity and glycaemic traits, suggesting the potential mechanisms by which built environment influences cardiometabolic health.

Abstract
GVHD remains a major source of morbidity and mortality after allogeneic BMT. GVHD is mediated by alloreactive T cells derived from the hematopoietic graft that target host tissues. Pre-clinical models have shown that presentation of alloantigens by host DCs results in the activation of donor-derived T cells that mediate GVHD. Strategies that interfere with the Ag-presenting capacity of DCs after allogeneic transplantation may decrease the risk of developing GVHD. Vitamin D is a hormone essential for calcium metabolism that shows immunomodulatory properties. We showed that correction of vitamin D deficiency appeared to mitigate manifestations of GVHD. In pre-clinical studies, we have shown that vitamin D inhibits DC maturation, polarizes T-cell populations toward the expression of Th2 as compared with Th1 cytokines, and blunts allogeneic T-cell proliferation in response to DC stimulation. Exposure to vitamin D resulted in increased expression of IDO, an enzyme responsible for tryptophan metabolism that is upregulated in tolerizing DCs. These data suggest that exposure to vitamin D results in immature DC populations that bias toward tolerizing rather than stimulatory T-cell populations. Vitamin D may therefore have a role in the prevention of GVHD.

Abstract
10556 Background: Dendritic cells (DC) play a key role in the development of tumor specific immune responses. Dendritic cells differentiated from leukemic blasts (LDC) are being explored as a tumor vaccine in AML. We examined the phenotypic and functional characteristics of LDC, the phenotypic characteristics of native DC in AML patients, and the effect of leukemic blasts on the phenotype of DC generated from normal donors. Methods: Leukemia blasts were isolated from peripheral blood of 24 patients with AML. LDC were generated by culturing blasts in the presence of GM-CSF, IL-4 and TNFa for 7 days. The phenotype of circulating DC1 (CD11C+/lin-) and DC2 (CD123+/ lin-) in AML patients was assessed by multichannel FACS analysis. To assess the effect of blasts on DC maturation, adherent mononuclear cells were isolated from normal donors, combined with leukemia cells in a 10:1 ratio, and cultured with GM-CSF, IL-4, and TNFa. Results: LDC demonstrate only modest expression of the costimulatory molecules CD80 and CD86 (mean expression 10% and 32%) and poorly express the maturation marker CD83 (mean expression 4%). Interferon gamma production by autologous T cells was not higher after stimulation with LDC than with blasts. LDC stimlation resulted in a 2 fold increase in both CD4+/CD25+/CD69+ (activated) and CD4+/CD25+/FOXP3+ (regulatory) T cells. Given the inability of leukemia progenitors to differentiate into phenotypically mature DC, we assessed whether leukemia cells directly inhibit differentiation of DC from normal progenitors. Expression of costimulatory molecules was decreased in DC differentiated in the presence of blasts. Mean expression of CD80, CD83, and CD86 was 16%, 2%, 83% and 49%, 10%, 99% for DCs generated in the presence or absence blasts respectively. Phenotypic characteristics of native DC in patients with AML were examined. In 3 experiments, a predominance of DC2 was seen (ratio DC2/DC1 5), and both DC1 and DC2 poorly expressed CD83 (mean expression 9% DC1, 0.9% DC2). Conclusions: LDC have phenotypic and functional deficiencies, limiting their efficacy as a tumor vaccine. Contact with leukemic blasts may inhibit DC maturation in vitro and in vivo, which may contribute to the lack of effective antitumor immunity in AML patients. No significant financial relationships to disclose.

Abstract
Since 1997 there has been increasing interest in the development of analytical methods for the analysis of perchlorate. The US Environmental Protection Agency (EPA) Method 314.0, which was used during the first Unregulated Contaminant Monitoring Regulation (UCMR) cycle, supports a method reporting limit (MRL) of 4.0 microg/L. The non-selective nature of conductivity detection, combined with very high ionic strength matrices, can create conditions that make the determination of perchlorate difficult. The objective of this work was to develop an automated, suppressed conductivity method with improved sensitivity for use in the second UCMR cycle. The new method, EPA Method 314.1, uses a 35 mm x 4 mm cryptand concentrator column in the sample loop position to concentrate perchlorate from a 2 mL sample volume, which is subsequently rinsed with 10 mM NaOH to remove interfering anions. The cryptand concentrator column is combined with a primary AS16 analytical column and a confirmation AS20 analytical column. Unique characteristics of the cryptand column allow perchlorate to be desorbed from the cryptand trap and refocused on the head of the guard column for subsequent separation and analysis. EPA Method 314.1 has a perchlorate lowest concentration minimum reporting level (LCMRL) of 0.13 microg/L in both drinking water and laboratory synthetic sample matrices (LSSM) containing up to 1,000 microg/L each of chloride, bicarbonate and sulfate.

Abstract
BACKGROUND Previous studies suggest that high risk and low birthweight babies have better outcomes if born in hospitals with level III neonatal intensive care units. Relations between obstetric care, particularly intrapartum interventions and perinatal outcomes, are less well understood, however. OBJECTIVE To investigate effects of obstetric, paediatric, and demographic factors on rates of hospital stillbirths and neonatal mortality. METHODS Cross sectional data on all 65 maternity units in all Thames Regions, 1994-1996, covering 540 834 live births and stillbirths. Hospital level analyses investigated associations between staffing rates (consultant/junior paediatricians, consultant/junior obstetricians, midwives), facilities (consultant obstetrician/anaesthetist sessions, delivery beds, special care baby unit, neonatal intensive care unit cots, etc), interventions (vaginal births, caesarean sections, forceps, epidurals, inductions, general anaesthetic), parental data (parity, maternal age, social class, deprivation, multiple births), and birthweight standardised stillbirth rates and neonatal mortality. RESULTS Unifactorial analyses showed consistent negative associations between measures of obstetric intervention and stillbirth rates. Some measures of staffing, facilities, and parental data also showed significant associations. Scores for interventional, organisational, and parental variables were derived for multifactorial analysis to overcome the statistical problems caused by high intercorrelations between variables. A higher intervention score and higher number of consultant obstetricians per 1000 births were both independently and significantly associated with lower stillbirth rates. Organisational and parental factors were not significant after adjustment. Only Townsend deprivation score was significantly associated with neonatal mortality (positive correlation). CONCLUSIONS Birthweight adjusted stillbirth rates were significantly lower in units that took a more interventionalist approach and in those with higher levels of consultant obstetric staffing. There were no apparent associations between neonatal death rates and the hospital factors measured here.

Abstract
Although high-dose chemotherapy (HDC) with stem cell rescue for the treatment of women with metastatic breast cancer (MBC) is currently a controversial strategy, we report the long-term outcomes of women undergoing high-dose therapy for MBC over the past 12 years while participating in a sequence of research studies transitioning between a single to a double intensification approach. Univariate and multivariate analyses provide a framework to understand the prognostic factors important for event-free and overall survival. Between May 1988 and April 1998, we enrolled 188 women with MBC into 3 trials of previously reported sequential transplantation strategies. Trial I (long induction/single transplantation) accepted 62 women in partial or complete response to an unspecified induction therapy and treated them with high-dose CTCb (cyclophosphamide, thiotepa, and carboplatin) supported by marrow or peripheral blood progenitor cells (PBPC). Trial II (long induction/double transplantation) accepted 68 women in partial or complete response to an unspecified induction therapy, and mobilized stem cells with 2 cycles of AF (doxorubicin and 5-fluorouracil) with granulocyte colony-stimulating factor (G-CSF). These women then received 1 cycle of high-dose single-agent melphalan followed 3 to 5 weeks later by CTCb, each with marrow or PBPC support. Trial III (short induction/double transplantation) enrolled 58 women prior to chemotherapy treatment for metastatic disease. Induction/mobilization consisted of 2 cycles given 14 days apart of doxorubicin and G-CSF. In contrast to trials I and II, patients with stable disease or better response to induction were eligible to proceed ahead with 2 cycles of HDC, 1 being CTCb and the other being dose escalated paclitaxel together with high-dose melphalan (TxM). These 2 HDC regimens were administered 5 weeks apart. TxM was given first in 32 patients and CTCb was given first in 26 patients. The median follow-up periods for trials I, II, and III were 98, 62, and 39 months from the initiation of induction chemotherapy and 92, 55, and 36 months from last high-dose therapy, respectively. The patient characteristics upon entry into these trials were similar. Important differences were that only those patients achieving a partial response or better to induction therapy were enrolled and analyzed for trials I and II, but all patients were analyzed on an intent-to-treat basis for trial III, including those who did not receive intensification. The median event-free survival (EFS) times from induction chemotherapy were 13, 19, and 27 months for trials I, II, and III, respectively (III versus I + II, P = .0004; III versus I, P = .0005; III versus II, P = .005; II versus I, P = .25). The median overall survival (OS) times from induction chemotherapy were 30, 29, and 57 months for trials I, II, and III, respectively (III versus I + II, P = .002; III versus I, P = .003; III versus II, P = .009; II versus I, P = .47). By multivariate Cox regression, participation in the short induction/double transplantation trial III and having no prior adjuvant chemotherapy remained favorable prognostic factors for both EFS and OS. The presence of visceral disease shortened EFS, and hormone sensitivity was of borderline significance. No substantive differences in the characteristics of the patient populations between the 3 trials appeared to interact with outcomes. In conclusion, we found that single transplantation in responding patients after long induction achieves a small cohort of long-term survivors, similar to the results reported by other transplantation centers. Adding a cycle of single-agent high-dose melphalan in this context delayed median time to relapse but did not affect long-term EFS or OS. The double transplantation approach using CTCb and TxM early in the course of treatment was associated with the best EFS and overall survival and was safe, feasible, and tolerable. Treatment duration was only 14 weeks, and this treatment option eliminated lengthy induction chemotherapy. Although selection biases may have in part contributed to this effect, a randomized comparison of standard therapy versus short induction/double transplantation is warranted.

Abstract
A number of problems associated with league tables of performance indicators have been discussed in the literature. This paper attempts to address these problems for stillbirth and infant mortality rates in order to produce meaningful and useful information for the government, general public and health professionals. Composite stillbirth and infant mortality rates, low birth-weight and very low birth-weight rates were determined for the 100 English Health Authorities for 1996-1997. Townsend deprivation scores for these districts were also obtained. The mortality rates were adjusted by multiple regression for very low birth-weight and Townsend score separately and together. Confidence intervals were calculated for the dual-adjusted rates. Almost 60% of the variability in mortality rates were explained by Townsend score and very low birth-weight rates together. Adjusted league tables showed how the individual and combined predictors affect the individual mortality rates for each Health Authority. There was considerable overlap in the confidence intervals for the adjusted rates although there were a few Health Authorities whose mortality rates were clearly below most others. We conclude that fairer and more useful information is provided by geographically based league tables which give both crude rates and rates adjusted for single and multiple predictor variables. The inclusion of confidence intervals aids interpretation of annual random variations and knowledge of differences in the effects of the individual predictors enables better resource targeting.

Abstract
Murine bone marrow (BM) NK T cells can suppress graft-vs-host disease, transplant rejection, and MLRs. Human BM contains T cells with similar potential. Human BM was enriched for NK T cells, approximately 50% of which recognized the nonpolymorphic CD1d molecule. In contrast to the well-characterized blood-derived CD1d-reactive invariant NK T cells, the majority of human BM CD1d-reactive T cells used diverse TCR. Healthy donor invariant NK T cells rapidly produce large amounts of IL-4 and IFN-gamma and can influence Th1/Th2 decision-making. Healthy donor BM CD1d-reactive T cells were Th2-biased and suppressed MLR and, unlike the former, responded preferentially to CD1d(+) lymphoid cells. These results identify a novel population of human T cells which may contribute to B cell development and/or maintain Th2 bias against autoimmune T cell responses against new B cell Ag receptors. Distinct CD1d-reactive T cell populations have the potential to suppress graft-vs-host disease and stimulate antitumor responses.

Abstract
Two cycles of high-dose chemotherapy with stem cell support (HDC) may increase the total dose delivered and dose intensity. A brief induction phase and different non-cross-resistant agents for each HDC cycle were used to avoid drug resistance. Twenty-six women with metastatic BC had induction and stem cell mobilization with two cycles of doxorubicin/G-CSF given every 14 days. Patients with stable disease or better after induction received HD CTCb followed by HD melphalan and dose-escalated paclitaxel. At 475 mg/m(2) of paclitaxel by 24-h infusion, dose-limiting transient peripheral sensory neuropathy was encountered. No toxic deaths occurred. Complete and near complete response after completion of therapy was achieved in 22 (85%) of 26 patients. The median EFS was 38 months. The median OS has not yet been reached. At a median follow-up of 33 (25-43) months, actuarial EFS and OS were 54% (95% confidence interval (CI), 39-69%) and 69% (95% CI, 56-79%), respectively. This double transplant approach lasts only 14 weeks and is feasible, safe, and tolerable. Whilst selection biases may in part contribute to favorable EFS and OS, a randomized comparison of standard therapy vs double transplant in both metastatic and locally advanced breast cancer is warranted.

Abstract
A single cycle of high-dose chemotherapy with stem cell support (HDC) in women with responsive metastatic breast cancer (BC) consistently achieves over 50% complete and near complete response (CR/nCR). This significant cytoreduction results in a median event-free survival (EFS) of 8 months, and approximately 20% 3-year and 16% 5-year EFS in selected patients. To improve long-term outcomes, new strategies to treat minimal residual tumor burden are needed. Increased total dose delivered can be achieved with two cycles of HDC. Critical design issues include shortening induction chemotherapy to avoid development of drug resistance and the use of different agents for each HDC cycle. We have determined the maximum tolerated dose (MTD) for paclitaxel combined with high-dose melphalan in the context of a double transplant and explored the impact of a short induction phase. Between June 1994 and August 1996, we enrolled 32 women with metastatic BC on to this phase I double transplant trial. Induction consisted of doxorubicin 30 mg/m2/day days 1-3 given for 2 cycles every 14 days with G-CSF 5 microg/kg s.c. days 4-12. Stem cell collection was performed by leukapheresis in each cycle when the WBC recovered to above 1000/microl. Patients with stable disease or better response to induction were eligible to proceed with HDC. HDC regimen I (TxM) included paclitaxel with dose escalation from 0 to 300 mg/m2 given on day 1 and melphalan 180 mg/m2 in two divided doses given on day 3. HDC regimen II was CTCb (cyclophosphamide 6 g/m2, thiotepa 500 mg/m2, and carboplatin 800 mg/m2 total doses) delivered by 96-h continuous infusion. At the first dose level of 150 mg/m2 paclitaxel by 3 h infusion, four of five patients developed dose-limiting toxicity consisting of diffuse skin erythema and capillary leak syndrome. Only two of these five completed the second transplant. Subsequently, paclitaxel was delivered by 24-h continuous infusion together with 96 h of dexamethasone and histamine receptor blockade. This particular toxicity was not observed again. No toxic deaths occurred and dose-limiting toxicity was not encountered. Three patients were removed from study prior to transplant: one for insurance refusal and two for disease progression. All others completed both cycles of transplant. Complete and near complete response (CR/nCR) after completion of therapy was achieved in 23 (72%) of 32 patients. The median EFS is 26 months. The median overall survival has not yet been reached. At a median follow-up of 58 months, EFS and overall survival are 41% and 53%, respectively. This double transplant approach is feasible, safe, and tolerable. Treatment duration is only 14 weeks and eliminates lengthy induction chemotherapy. The observed event-free and overall survivals are promising and are better than expected following a single transplant. Whilst selection biases may in part contribute to this effect, a much larger phase II double transplant trial is warranted in preparation for a potential randomized comparison of standard therapy vs single vs double transplant.

Abstract
The present study examines the nature of humoral and cellular immune reconstitution in 28 patients with advanced breast cancer following high-dose chemotherapy with stem cell rescue. Patients underwent testing of T, B, NK and dendritic cell function at serial time points until 1 year post transplant or until the time of disease progression. Abnormalities in T cell phenotype and function were observed following high-dose chemotherapy that persisted for at least 6-12 months. The vast majority of patients experienced an inversion of the CD4/CD8 ratio and demonstrated an anergic response to candida antigen. Mean T cell proliferation in response to PHA and to co-culture with allogeneic monocytes was significantly compromised. In contrast, mean IgG and IgA levels were normal 6 months post transplant and NK cell yields and function were transiently elevated following high-dose chemotherapy. Dendritic cells generated from peripheral blood progenitors displayed a characteristic phenotype and were potent inducers of allogeneic T cell proliferation in the post-transplant period. The study demonstrates that patients undergoing autologous transplantation for breast cancer experience a prolonged period of T cell dysfunction. In contrast, B, NK, and DC recover more rapidly. These findings carry significant implications for the design of post-transplant immunotherapy.

Abstract
This study investigates which, if any, population-based indicator of deprivation best predicts foetal and infant mortality rates in England. For the year 1995, the deprivation levels of 364 English Local Authorities were compared; using the three commonly used indicators, Jarman score, Townsend score and percentage unemployed. The predictive value of these for stillbirth, neonatal and infant mortality rates was then calculated. The three deprivation indicators were highly inter-correlated (r=0.866-0.924). For each mortality rate, the correlation with deprivation did not differ significantly for the three indicators of deprivation. We conclude, when comparing these outcomes in different areas of England, that any of the three deprivation indicators may be used to adjust for deprivation.

Abstract
Dendritic cells (DCs) are potent antigen-presenting cells that are essential for the initiation of T cell-mediated immunity. DCs develop from myeloid progenitor populations under the influence of granulocyte macrophage colony-stimulating factor (GM-CSF) and pass through an intermediate stage of maturation that is characterized by CD14 expression. Interest has focused on generating human-derived DCs for antigen-specific tumor vaccines to be used as adjuvant immunotherapy in minimal disease settings, such as after autologous transplantation. In the present study, mobilized peripheral blood progenitor cells (PBPCs) were obtained from 18 patients with locally advanced or metastatic breast cancer preparing to undergo autologous stem cell transplantation. PBPCs mobilized in 10 patients with GM-CSF for 1 week, followed by the combination of GM-CSF and G-CSF, were compared with those obtained from patients receiving G-CSF alone with respect to the presence of DC progenitors and the capacity to generate functionally active mature DCs. PBPCs mobilized with GM-CSF/G-CSF were markedly enriched for CD14+ DC progenitor cells as compared with those mobilized with G-CSF alone. Consistent with an immature progenitor population, the CD14+ cells express Ki-67 antigen but not nonspecific esterase. CD14+ cells purified by fluorescence-activated cell sorting from PBPCs mobilized with either regimen and cultured for 1 week in GM-CSF and interleukin-4 generated nearly pure populations of cells with characteristic DC phenotype and function. The addition of GM-CSF to the mobilization regimen resulted in greater yields of functionally active DCs for potential use in posttransplant immunotherapy.

Abstract
This study investigates whether social class or a census-based deprivation score is a better predictor of stillbirth rates using data for 1993-5 for residents of South Thames (West) Region. Social class is routinely coded for 10% of live births and 100% of stillbirths. A Townsend deprivation score was assigned to each stillbirth and each live birth with a social class code, according to their electoral ward of residence. In unifactorial analyses of stillbirth rate the relationship was stronger with social class (P = 0.008) than with Townsend score (P = 0.11). Both relationships were strengthened by including those births recorded as social class 'other' ['other' vs. social class I odds ratio (OR) = 2.27, P < 0.001; lower vs. upper septile deprivation score OR = 1.45, P = 0.07)]. When social class and Townsend score were analysed together, the ORs for social class remained similar to before, but the Townsend ORs were reduced and non-significant overall. We conclude that social class, which is based on data on each individual, is a better predictor of stillbirth than Townsend score, which is based on data from the area of residence. We recommend further investigation of the stillbirth risk in the subgroups that make up the 'other' social class.

Abstract
BACKGROUND There has been no previous work investigating the effects of furred pet ownership and pillow type on the risk of developing rhinitis. Recently, unexpected and unexplained associations of asthma with nonfeather pillows have been reported. OBJECTIVE We developed a questionnaire-based cross-sectional survey to determine whether the past or present ownership of cats or dogs, or the use of nonfeather pillows contributes to the development of seasonal or perennial rhinitis. METHODS We surveyed 2555 accompanying friends and relatives of patients attending the outpatients departments at one London hospital in 1996. Individuals with rhinitis were defined as those suffering with three or more symptoms of rhinitis either throughout the year (perennial) or for part of the year (seasonal). Present or childhood ownership of cats or dogs was recorded. RESULTS A strong association was seen with nonfeather pillow use and both seasonal [odds ratio (OR) 1.85; 95% confidence interval (CI) 1.43-2.5] and perennial (OR 2.63; CI 1.67-5. 0) rhinitis. However, more than one-third of rhinitics had changed their pillow type. After restricting the data to exclude subjects who changed their pillow to avoid allergies, the strong association of nonfeather pillow use with perennial rhinitis remained (OR 2.44; CI 1.25-5.0). Adjusting the data to the extreme situation where all former pillow type was feather changes the apparent risk to 0.99 (CI 0.67-1.43). No associations for either seasonal or perennial rhinitis were seen for feather pillows. A weak association of current dog ownership is demonstrated for seasonal rhinitis (OR 1. 47; CI 1.01-2.14). No associations were seen for childhood dog ownership or cat ownership at any time with either type of rhinitis. CONCLUSIONS Feather pillow use and the ownership of furred pets appears unlikely to increase the risk of developing perennial or seasonal rhinitis. In fact, in contrast with currently held views, there is evidence that the use of nonfeather pillows may increase the risk.

Abstract
Nausea and vomiting are significant side effects in bone marrow transplant (BMT) patients who receive high-dose preparative regimens. Higher than conventional ondansetron doses and continuous infusion might improve emetic control, because of the high doses and combinations of chemotherapy (CT) used in this setting. Our objective was to conduct a prospective, randomized study comparing two different administration methods of high-dose ondansetron during a BMT preparative regimen in breast cancer patients. Patients were eligible if they were nonpregnant women over 18 but under 65 years of age, undergoing highly emetogenic CT in preparation for autologous BMT. All patients received ondansetron as an intermittent (INT = 24 mg i.v. q 12 h/day) or continuous intravenous infusion (CIV = 8 mg i.v. loading dose followed by a continuous infusion of 2 mg/h per day). A total of 66 patients were enrolled in the study (n = 34, INT; n = 32, CIV). There was no statistical difference between treatment groups in the worst grade of emesis for the entire study period (P = 0.49). Greater than 90% of all patients were graded as failures (> or = 5 emetic episodes or need for rescue antiemetics). Complete control (no vomiting episodes) and complete plus major control (1-2 emetic episodes) per day ranged from 8% to 85% and 11% to 91%, respectively. There was no significant difference between the treatment arms in: grade of emesis, episodes of vomiting and retching, nausea scores, and mean number of rescue medications administered. There were no differences in efficacy when high-dose ondansetron was given as CIV or INT for the control of nausea and vomiting in breast cancer patients undergoing high-dose CT for autologous BMT. Ondansetron alone was not adequate to provide sustained control of CT-induced nausea and vomiting over the entire 5-day study period. A combination of antiemetics targeting various mechanisms of CT-induced nausea and vomiting may be necessary to improve response rates.

Abstract
Our objectives were to measure and compare plasminogen activator inhibitor levels (PAI-1) in primary adult thrombotic thrombocytopenic purpura (TTP) and in secondary TTP associated with bone marrow transplantation (BMT)-TTP. PAI-1 antigen levels were measured by an enzyme linked immunosorbent assay on platelet poor plasma samples obtained from patients at the time of diagnosis of the TTP disorder and from a group of normal volunteers. The samples were frozen at -70 degrees C. Patients with TTP secondary to bone marrow transplantation had their grade determined by percentage fragmented cells and lactate dehydrogenase levels. The primary TTP samples were contributed by investigators in the multi-institutional North American TTP Group, and the bone marrow transplant samples were obtained from an adult bone marrow transplant program. Nineteen patients with adult TTP, and 47 patients with bone marrow transplant-TTP were evaluated. Of the latter, 14 had Grade 2, 13 had Grade 3, and 20 had Grade 4 BMT-TTP. PAI-1 levels were elevated compared to control volunteers in both primary adult TTP and BMT-TTP, P < 0.001. Levels did not differ from normal in Grade 2 BMT-TTP (median = 16 ng/ml; quartiles = 9-20). PAI-1 levels were similar in primary TTP (median = 32 ng/ml; quartiles = 25-51) and Grade 3 BMT-TTP (median = 35 ng/ml; quartiles = 19-48 ng/ml), P = 0.7. However, PAI-1 levels were significantly higher in Grade 4 BMT-TTP (median = 83 ng/ml; quartiles = 60-143) than Grade 3 BMT-TTP, and primary TTP, P < 0.001. PAI-1 levels are high in primary TTP and secondary bone marrow transplant-TTP (Grades 3-4). In contrast, normal levels are seen in Grade 2 BMT-TTP, which is a self-limited disorder. Therefore, high PAI-1 levels may contribute to hypofibrinolysis in the pathogenesis of primary TTP and of moderate to severe TTP (Grades 3-4) following bone marrow transplantation.

Abstract
PURPOSE A pilot study of the antiandrogen bicalutamide at 150 mg. a day for androgen independent prostate cancer was performed. This study was based on the possibility that androgen independent cases might display responses to additional hormonal agents. MATERIALS AND METHODS The study included 31 androgen independent cases with an increasing prostate specific antigen (PSA) and progressive disease. PSA measurements were used as the primary method of assessing response. However, PSA decline was also correlated with clinical status. RESULTS Seven patients demonstrated PSA declines of greater than 50% for 2 months or more, for an overall response rate of 22.5%. Responses were observed almost exclusively in patients treated with long-term flutamide as part of a complete androgen blockade regimen (43% response rate) in contrast to patients treated with androgen deprivation without flutamide (6% response rate). Of the 7 PSA responding patients bicalutamide resulted in a significant improvement in performance status and a decrease in analgesic requirement in 4 and 3 remained asymptomatic. Bicalutamide at 150 mg. a day was well tolerated, with the most frequent side effect being mild exacerbation of hot flashes. CONCLUSIONS Bicalutamide at this dose is modestly effective for some patients with androgen independent prostate cancer, particularly for those previously treated with long-term flutamide. This study indicates that previous antiandrogen therapy alters the response to subsequent hormonal agents.

Abstract
We set out to review the need for general practitioners (GPs) to be skilled at forming an emergency alternative airway by assessing mortality figures for acute airways obstruction. We also solicited the views of 100 GPs on the theory and practice of emergency tracheostomy and assessed whether they considered they were equipped to carry out such a procedure in the community. The results suggest a significant number of deaths of otherwise young and healthy individuals could be avoided by training community practitioners in emergency alternative airway formation. The results showed a marked lack of confidence in the practice of emergency airway formation and few GPs felt able to carry out the procedure. They indicated an overwhelming interest in receiving further education on the subject. We recommend that formal training programmes in the techniques of emergency airway formation should be available for community GPs.

Abstract
BACKGROUND Clinical observations of a relationship between unpleasant dreams and migraine headaches have been reported previously. METHODS Due to the anecdotal quality of these case reports, this study empirically investigated the significance of this relationship. Dream content categories were selected corresponding to emotional factors associated with stress that trigger migraine headaches. A total of 37 migraineurs recorded 10 dreams each, 5 that preceded migraines and 5 that did not. RESULTS Univariate F tests revealed that 4 of the 5 variables contributed significantly to the overall effect, specifically anger, misfortune, apprehension, and aggressive interactions. CONCLUSIONS Recommendations include discussing the predictive value of dreams with regard to nocturnal migraine attacks, and therapeutic implications are suggested.

Abstract
Stromelysin-3 expression was studied by Northern blotting in 222 tissue samples including primary and metastatic breast carcinoma and normal breast tissue. Uninvolved breast tissue from mastectomy specimens, normal breast tissue from reduction mammoplasties and normal lymph nodes did not contain stromelysin-3 mRNA. About 62% of primary and metastatic breast carcinomas, but only 1 of 10 in situ ductal carcinomas, expressed stromelysin-3. Stromelysin-3 mRNA was found more often in estrogen-receptor-positive carcinomas and in histological grade-1 carcinomas. There was no significant correlation between stromelysin-3 expression and other prognostic factors, including tumor size, lymph-node involvement, age of patient, vascular invasion and cathepsin-D.

Abstract
pS2 mRNA was estimated in uninvolved breast tissue and breast carcinoma from the same patients. pS2 mRNA was clearly detected in 14 of 59 uninvolved breast tissues and in 30 of 58 breast carcinomas. pS2 mRNA was found more frequently in uninvolved breast tissue of premenopausal women than in that of postmenopausal women.

Abstract
A case of disseminated Kaposi's sarcoma (KS) in a 21-yr-old white heterosexual male with cryptogenic cirrhosis and no serological or immunological evidence of acquired immune deficiency syndrome (AIDS) is reported. The patient died 2 wk after diagnosis. Postmortem examination showed involvement of lymph nodes, liver, spleen, gastrointestinal tract, and bone marrow. This case demonstrates that Kaposi's sarcoma can occur in a young heterosexual male with normal immune function and in the absence of HIV infection.

Abstract
Levels of plasma daunorubicin, daunorubicinol and aglycone metabolites were measured in 47 patients 3 h after daunorubicin was administered daily for three days as part of a cytosine arabinoside/daunorubicin remission induction regimen. High-pressure liquid chromatography with fluorescence detection was used for separation and quantitation of the drug and its metabolites. A wide range of plasma levels were observed regardless of the outcome of therapy. Patients who had high levels of the drug, or daunorubicinol on day 1 of therapy tended to have high levels on days 2 and 3 of the regimen. Three hours after the third daily dose of daunorubicin was administered, patients who would not enter remission had significantly higher levels of aglycone metabolites in plasma than did patients who entered remission. These data indicate that resistance to chemotherapeutic effects of daunorubicin may be connected with metabolism of the drug, especially with enhanced metabolism to aglycones.

Abstract
Photovoltaic indium antimonide detectors have been operated at temperatures </=77 K with sufficiently low background radiation levels that Johnson noise limited performance is realized. Under such conditions the noise equivalent power (NEP) is completely determined by the detector operating temperature, resistance, and quantum efficiency. Optimization of these parameters in the manufacture of commercially available detectors has led to 5-mum NEP's as low as 10(-15) W. The particular preamplifier is critical to the achievement of Johnson noise limited operation and is described in detail.
