Abstract
BACKGROUND Glial tumors are the most common tumors of the central nervous system, affecting individuals of all ages. Conventional cytogenetics have been unable to identify a consistent chromosomal translocation or rearrangement in this group of tumors; thus, more advanced molecular cytogenetic approaches are required. METHODS AND RESULTS In this study, 16 glial tumors, including two recurrences and six glioma cell lines, were analyzed by spectral karyotyping (SKY) and comparative genomic hybridization (CGH). From 169 rearrangements detected by SKY, chromosomes 1 and 10 were the most frequently affected by translocation (18 of 169 and 16 of 169 rearrangements, respectively). Other frequently altered chromosomes included chromosomes 3 (13 of 169 rearrangements), 5 (ten of 169 rearrangements), 7 (ten of 169 rearrangements ), and 11 (ten of 169 rearrangements). A clustering of centromeric breakpoints was detected in chromosomes 3, 5, 10, 11, 16, 17, and 20. CGH analysis identified consistent gain of part or all of chromosome 7 among the 10 astrocytic tumors (five of ten specimens) in the study group. Analysis of the three gangliogliomas and one ependymoma identified a much simpler pattern of primarily numerical change. CONCLUSION Application of improved cytogenetic methods can increase our abilities to progress toward effective strategies of molecular diagnosis and classification of glial tumors.

Abstract
Background
—Use of β-adrenoreceptor blockade in the treatment of heart failure has been associated with a reduction in myocardial oxygen consumption and an improvement in myocardial energy efficiency. One potential mechanism for this beneficial effect is a shift in myocardial substrate use from increased free fatty acid (FFA) oxidation to increased glucose oxidation.
Methods and Results
—We studied the effect of carvedilol therapy on myocardial FFA and glucose use in 9 patients with stable New York Heart Association functional class III ischemic cardiomyopathy (left ventricular ejection fraction ≤35%) using myocardial positron emission tomography studies and resting echocardiograms before and 3 months after carvedilol treatment. Myocardial uptake of the novel long chain fatty acid metabolic tracer 14(R, S)-[
18
F]fluoro-6-thia-heptadecanoic acid ([
18
F]-FTHA) was used to determine myocardial FFA use, and [
18
F]fluoro-2-deoxy-glucose ([
18
F]-FDG) was used to determine myocardial glucose use. After carvedilol treatment, the mean myocardial uptake rate for [
18
F]-FTHA decreased (from 20.4±8.6 to 9.7±2.3 mL · 100 g
–1
· min
–1
;
P
<0.005), mean fatty acid use decreased (from 19.3±7.0 to 8.2±1.8 μmoL · 100 g
–1
· min
–1
;
P
<0.005), the mean myocardial uptake rate for [
18
F]-FDG was unchanged (from 1.4±0.4 to 2.4±0.8 mL · 100 g
–1
· min
–1
;
P
=0.14), and mean glucose use was unchanged (from 11.1±3.1 to 18.7±6.0 μmoL · 100 g
–1
· min
–1
;
P
=0.12). Serum FFA and glucose concentrations were unchanged, and mean left ventricular ejection fraction improved (from 26±2% to 37±4%;
P
<0.05).
Conclusions
—Carvedilol treatment in patients with heart failure results in a 57% decrease in myocardial FFA use without a significant change in glucose use. These metabolic changes could contribute to the observed improvements in energy efficiency seen in patients with heart failure.

Abstract
Several renal cell carcinoma (RCC) prognostic factors show promise, including K1-67, p53/mdm-2, and vascular endothelial growth factor. The combination of increased incidence of RCC and diagnosis during earlier stages has generated interest in local therapeutic options. Nephron-sparing surgery and laparoscopic nephrectomy continue to gain support and may become the standard of care in select patients. Standard therapy for metastatic disease continues to be cytokine-based therapy with little benefit gained from adding granulocyte-macrophage-colony-stimulating factor, retinoic acid, or adoptive immunotherapy. The addition of chemotherapy, such as capecitabine, floxuridine, and vinblastine, may increase the effectiveness of immunotherapy; nonmyeloablative stem cell transplantation has shown early promise in metastatic disease.

Abstract
Point-of-care testing (POCT) is an increasingly popular method of delivering laboratory testing. Management of POCT is challenging given the variety of devices, locations, and staff that need to be coordinated to ensure quality results and meet regulatory guidelines. Electronic capture and transfer of data are preferred for managing POCT, but there is currently no standard method of connecting different devices. Johns Hopkins Medical Institutions (JHMI) developed a common data management system with interfaces to all of its POCT devices. All POCT data are collected in one database and analyzed in a similar fashion. Where data were once collected by carrying laptops to each nursing unit, the POCT devices can now connect directly to the database over the Internet. Algorithms have been created to automate the data analysis and review process. Over the several years that this software has been used, JHMI has experienced improved quality, accuracy, and management of its POCT program. The labor saved by increased automation of data review is refocused on enhancing the performance and scope of the program. Current connectivity and analysis algorithms have future application to remote consultation, management of home self-monitoring patients, and examination of real-time data.

Abstract
The aryl hydrocarbon receptor nuclear translocator (ARNT) is a basic helix-loop-helix transcription factor that forms heterodimers with the aryl hydrocarbon receptor (AhR) or hypoxia inducible factor-1alpha to activate transcription via xenobiotic response element or hypoxia response element, respectively. Thus, it plays a major role in two key biochemical pathways involved in tumor growth. We previously showed that estrogen receptor (ER)-negative breast cancer cell lines expressed a splice variant of ARNT that was associated with Ah nonresponsiveness. We have now used a sensitive PCR method to analyze the expression of the variant in a series of 92 breast cancers to assess interactions with the ER and prognosis. The splice variant could be detected in all of the cases examined, with high ratios of variant:full-length ARNT (> or =10) characterized in 10 cases. When the patient group was split into quartiles by increasing splice variant ratios, there was an inverse relationship of ER status to ARNT splice-variant ratios (P = 0.01, chi(2)). Univariate analysis showed that cases with high ARNT splice-variant ratios > or =10 had a worse relapse-free and overall survival (P > or = 0.03; hazard ratio, 2.7; and P = 0.006; hazard ratio, 3.9, respectively). In multivariate analysis for relapse-free and overall survival, ARNT splice-variant ratio was the strongest independent factor and, although inversely related to ER, remained a separate risk factor. At least two potential mechanisms could explain this phenomenon: the loss of aryl hydrocarbon receptor-mediated antiestrogenic activity or the blockade of a proapoptotic pathway induced by hypoxia. Because several enzymes involved in drug resistance are induced through a xenobiotic response element, the tumors presenting high ARNT splice-variant ratios may be specifically targeted by drugs normally degraded or inactivated. This study shows the biological importance of ARNT splice variants in the behavior of human breast cancer and suggests that the breast cell lines in which the splice variant was discovered may be useful models for further investigation.

Abstract
BACKGROUND The purpose of the current study is to evaluate the outcome of salvage treatment for local recurrence after breast-conserving surgery and radiation as initial treatment for mammographically detected ductal carcinoma in situ (DCIS; intraductal carcinoma) of the breast. METHODS An analysis was performed of 42 patients with local only first failure (n = 41) or local-regional only first failure (n = 1) after breast-conserving surgery and radiation treatment had been given for DCIS of the breast. Surgical treatment at the time of local recurrence included mastectomy (n = 37; 88%) or excision (n = 5; 12%). Adjuvant systemic therapy at the time of local recurrence was chemotherapy (n = 3; 7%), tamoxifen (n = 8; 19%), both (n = 1; 2%), none (n = 29; 69%), or unknown (n = 1; 2%). The median interval from the time of initial treatment to local recurrence was 4.8 years (range = 1.0-15.2 yrs). The median follow-up after salvage treatment was 4.5 years (range = 0.2-12.8 yrs). RESULTS At the time of the local recurrence, 22 patients (52%) had invasive ductal carcinoma, 18 patients (43%) had DCIS, 1 patient (2%) had invasive lobular carcinoma, and 1 patient (2%) had angiosarcoma. After salvage treatment, the rate of overall survival and the rate of cause specific survival for all 42 patients were 92% at both 5- and 8-years after treatment. The rate of freedom from distant metastases was 89% at 5 and 8 years. Favorable prognostic factors after salvage treatment were DCIS as the histology of the local recurrence and mammography only as the method of detection of the local recurrence. CONCLUSIONS The results of salvage treatment in the current study demonstrated that local recurrences were salvaged with high rates of survival and freedom from distant metastases. These results support the use of breast-conserving surgery and radiation for initial management of DCIS of the breast.

Abstract
Inherited succinic semialdehyde dehydrogenase (SSADH; EC1.2.1.24; McKusick 271980) deficiency is a defect of GABA degradation which leads to accumulation of 4-hydroxybutyric acid (gamma-hydroxybutyric acid; GHB) in physiologic fluids of patients. Prenatal diagnosis (PND) was performed in three at-risk pregnancies employing combinations of: (1) reverse-transcription-polymerase chain reaction (RT-PCR) and genomic DNA amplification followed by sequencing using isolated leukocytes or cultured human lymphoblasts; (2) GHB quantitation in amniotic fluid; or (3) SSADH enzyme assay in chorionic villus (CV) and/or amniocytes. In two pregnancies, all analyses were concordant for prediction of disease status in the fetus. In the third case, enzyme activity in CV (deficient) and metabolite analysis in amniotic fluid (normal) were discordant. For clarification, mutation analysis was undertaken in CV, confirming heterozygosity for the mutation previously identified in the proband. We hypothesize that delayed transit time for shipment of CV between Greece and the United States (8 days) led to enhanced degradation of heterozygous SSADH enzyme activity. Our data demonstrate the importance of combined metabolite, enzyme, and DNA analysis for increased accuracy in the PND of SSADH deficiency.

Abstract
A community-based cross-sectional study was undertaken to measure anthropometric indices, micronutrient status and prevalence of parasite infections in 579 rural South African primary school children. Eleven schools were selected randomly from a Magisterial District in southern KwaZulu-Natal (KZN). In each school, all pupils aged between 8 and 10 years were selected. The following outcome measures were obtained: anthropometric--height for age, weight for age and body mass index; micronutrient status--anaemia, serum ferritin and vitamin A; and prevalence of parasite infections--Ascaris lumbricoides, Trichuris trichiura and Schistosoma haematobium. The observed prevalences were: stunting 7.3%, underweight for age 0.7%, and obesity 3.1%; anaemia 16.5% (Hb < 12 g/dl), vitamin A deficiency 34.7% (serum retinol < 20 micrograms/dl) and 28.1% with reduced serum ferritin (< 12 ng/ml); Trichuris trichiura 53.9%, Ascaris lumbricoides 27.3% and Schistosoma haematobium 24.5%. We conclude that micronutrient deficiency, parasitic infestations and stunting remain significant problems among school-aged children in South Africa. Micronutrient supplementation and de-worming provide opportunities for school-based health promotion and primary health care interventions, and might produce significant health and educational benefits.

Abstract
Aim: To define the components and organization of a modern leg ulcer service that is acceptable to patients cost effective and produces high quality outcomes. Method: Analysis of data from published literature as well as experience from the organisation of a leg ulcer service in Gloucestershire. Synthesis: Assessment of leg ulcers requires the services of a vascular laboratory to assess the venous and arteria systems. Effective systems of compression must be employed. Staff and patients must be educated to understand the principals behind their use. For some patients pinch-grafting may be appropriate. Where arterial disease is present in the lower limb, reconstructive surgery should be used for the lower limb vessels The organisation of such a service must ensure good liaison between General Practitioners, community nurses and hospital specialists. Many patients may be managed in community leg ulcer clinics. In some cases, the advice of specialists such as rheumatologists and dermatologists may be required. Conclusions: A national framework for leg ulceir management is needed within which resources are made available in a way that satisfy local needs. Such a framework must be based on management protocols derived from evidence-based practices that have been developed through the experiences of modern leg ulcer services.
