Vaccarino1. 1 Emory University, Atlanta, GA; 2Mount Sinai School of Medicine, New York, NY; 3 Brown University, Providence, RI; 4Yale University, New Haven, CT. Tracking ID # 173479 ; BACKGROUND: Coronary artery disease CAD ; is the leading cause of mortality among men and women in US, and acute coronary syndromes ACS ; represent a large proportion of CAD events. Previous studies have shown that women with ACS are treated less aggressively than men. Most of these studies, however, have primarily involved patient samples undergoing invasive coronary procedures. Only a few have evaluated gender differences in the pharmacological treatment for ACS, and even fewer have have focused on African-American women, a patient group in which such disparities could be most marked. The purpose of this study was to examine gender differences in the receipt of initial pharmacological treatments according to national guidelines, in a predominantly African-American patient population admitted with suspected or con-firmed ACS. METHODS: We conducted a retrospective chart review of 600 consecutive patients admitted to Grady Memorial Hospital, Atlanta, GA, with an admission diagnosis of acute myocardial infarction AMI ; , unstable angina, rule-out AMI, and suspected unstable angina as defined by the American College of Cardiology Clinical Data Standards. The outcome variables were receipt of aspirin ASA ; , beta-blockers BB ; and anti-thrombin therapy ATT ; unfractionated heparin and low molecular weight heparin ; within 24 hours of hospital arrival. Multiple logistic regression models were conducted to compare the receipt of each treatment between men and women after adjusting for age, race, smoking, family history of CAD, past medical history of hypertension, diabetes or hypercholesterolemia, systolic blood pressure on admission and cardiac enzymes within 24 hours of admission. RESULTS: In the study period, 600 patients 268 men and 332 women ; were enrolled. Approximately 85% of patients were African-American. Women were more likely than men to be older, and to have Medicare and Medicaid for insurance all p 0.01 ; . Women also had more comorbid conditions as compared with men, including hypertension, higher body mass index, and prior history of AMI all p 0.01 ; . However, women were as likely as men to have history of diabetes, hypercholesterolemia and family history of CAD. Overall, 89% of the patients received ASA, with similar frequency in men and women 90% men versus 88% women; p 0.44 ; , and 60% received BB, again with similar rate by gender 56% men versus 63% women; p 0.12 ; . Only 47% patients received ATT 46% men versus 48% women; p 0.67 ; . After adjusting for other factors, gender remained a non significant predictor for the receipt of ASA [odds ratio OR ; 0.81; 95% CI 0.491.35], BB OR 1.30; 95% CI 0.941.80 ; or ATT OR 1.10; 95% CI 0.781.48 ; . CONCLUSIONS: In African-American patients with suspected or confirmed ACS, there were no gender differences in receipt of pharmacological agents within 24 hours of hospital arrival. Future studies are needed to confirm and examine the factors for the overall suboptimal usage of these interventions in African-American patient population.

Sensitiuity to Inhibitors of DNA and RNA PolymerasesWe have recently purified EMC virus 3DPo1 from recombinant E. coli and quantitated its polymerization activity using an oligo U ; -primed poly U ; polymerase assay Sankar and Porter, 1991 ; . This assay permits the sensitivity of the enzyme toward a range of inhibitors to be determined. As shown in Table IA, the EMC virus 3DPo1 poly U ; polymerase activity was resistant to rifampicin and heparin at concentrations which completely inhibit the activity of E. coli DNA-dependent RNA polymerase. Dactinomycin, an inhibitor of eukaryotic DNA-dependent RNA polymerases also had no effect on EMC virus 3DP0', which agrees with the findings for poliovirus Morrow et al., 1987; Rothstein et al., 1988 ; . Conversely, EMC virus 3DPo1 was highlysensitive to cerulenin at 100 and N-ethylmaleimide at 5 mM, while E. coli RNA polymerase was resistant to these compounds Table IA ; . Cerulenin, a specific inhibitor of fatty acylation and sterol biosynthesis, was tested because at 0.1 m it selectively M inhibits poliovirus plus strand RNA synthesis in poliovirusinfected cells Guinea andCarrasco, 1990 ; . Because cerulenin fails to inhibit the synthesis of poliovirus RNA in a cell-free system consisting of membrane-bound replication complexes, the suggestion was made that continuous phospholipid synthesis was required for poliovirus replication Guinea and Carrasco, 1990 ; . The inhibition of EMC virus 3DPo1 polymerization activity in a lipid-free assay is therefore surprising; the value of 1.25 p~ is well within the concentrations used in the experiments with poliovirus-infected cells Guinea and Carrasco, 1990 ; . In order to provide evidence that the inhibition by cerulenin is specific, another compound which affects cellular biosynthesis was tested. Brefeldin A, a drug which blocks protein secretion anddisrupts the Golgi structure Misumi et al., 1986 ; was found to have no effect on the in vitro activity of EMC virus 3DP' Table IA ; .

Increased hypercoagulability of warfarin when first initiated. The heparin treatment is stopped after 5 to 10 days once the INR from warfarin dosing is at a therapeutic level. The warfarin treatment is continued for at least 3 months in uncomplicated nonrecurrent DVT. Complications with heparin treatment include thrombocytopenia or thrombosis. Because of the risk and negative sequelae of heparin-induced thrombocytopenia, the platelet counts of patients on unfractionated or fractionated heparin LMWH ; should be monitored at least every 2 to 3 days. Significant reductions in the platelet count below 100, 000 L may require discontinuation of heparin therapy. Overdosage of heparin can cause significant clinical bleeding.1.

| Heparin injections and pregnancyIntroduction: Determination of amount of proteinuria is widely used to establish the diagnosis and response to treatment of most renal diseases and also to predict the prognosis 1 ; . This prospective study was designed to assess whether a single urine specimen, could estimate 24 h urinary protein excretion. Methods: The correlation between spot urinary protein creatinine ratio P Cr ; and 24 h urine protein excretion determined from 287 urine specimen of 185 patients was investigated. The ability of spot urine P Cr to predict different threshold levels of protein excretion was assessed using a series of receiver operator curves. Results: A linear relationship exists between the spot P Cr and 24 h protein excretion, with a correlation of 0.83, p 0.01 figure 1 ; . The correlation was weak when protein excretion higher than 10 g day r 0.35 ; . Spot urine P Cr values reliably predicted protein excretion thresholds of 0.5, 1.0 and 3.0 g day. The areas under curve in ROC analysis for 0.3, 1, and 3 gram day were 0.96, 0.98, and 0.95, respectively. The sensitivity and specifity values at these cutoffs were between 89% and 95%. Note from the publisher: An image was submitted to support this abstract. For technical reasons related to the submitted file, it has not been possible to include the image as part of this entry. Conclusion: High correlation numbers have been reported between spot P Cr and 24 h protein excretion in patients with diabetic nephropathy, renal transplantation, lupus nephritis, and pregnancy 2 ; . NKF-DOQI guidelines recommend spot P Cr to determine the amount of proteiuria 1 ; . Random spot urinary P Cr predicts actual 24 h protein excretion with reasonable accuracy but is unreliable in patients with high protein excretion and hepsera.

3. NEFA Nonesterified fatty acids are important among the peripheral factors controlling GH secretion. Pharmacological reduction of circulating NEFA levels raises GH 510 ; , but conversely, NEFA elevation induced by the combination of exogenous Intralipid plus heparin markedly reduces spontaneous GH secretion in different animal species 109, 342 ; and abolishes GH responses to various stimuli 175, 181, 342 ; . How NEFA act is not clear. In rats, NEFA's inhibitory effect is directed at the pituitary 30, 175 ; , but a hypothalamic site of action has also been suggested, since their in vivo inhibitory effect on GHRH-stimulated GH release was abolished by passive immunization with SS antiserum 505 ; . Similar conclusions were drawn from human studies 824 ; . At variance with these findings, experiments using monolayer cultures of fetal hypothalamic neurons showed that exposure to NEFA increased GHRH secretion and inhibited SS output, lowering SS mRNA content 949 ; . The differences in vivo and in vitro may result from disruption of the normal organization in cultured dispersed neurons or the use of fetal tissue. A pituitary site of action for NEFA was suggested again by Alvarez et al. 30 ; , who showed that their inhibitory effect on GHRH-stimulated GH release was also present in normal rats pretreated with a SS antiserum, or with hypothalamic ablation, and in hypophysectomized rats with two AP transplanted under the kidney capsule. The inhibitory effect of NEFA on GH secretion at the pituitary is rapid within minutes ; , dose and time dependent, and closely related to the chemical structure of the NEFA tested 175 ; . Although this point has not been completely clarified, the most likely mechanism is a reduction of [Ca2 ]i. Cis-unsaturated NEFA, such as oleic acid, at physiological concentrations, suppressed the TRH-induced increase in Ca2 in primary cultures of pituitary cells and in GH3 and GH4C1 cells. In the same cells, NEFA abolished the TRH-induced Ca2 efflux, through plasma membrane Ca2 pumps, suggesting they perturbed the function of integral membrane proteins 829 ; . In summary, the inhibitory influence of NEFA on GH secretion appears to be mainly exerted in the pituitary. 4. Leptin Leptin, the product of the ob gene, is a recently discovered hormone secreted by adipocytes 1128 ; that regulates food intake and energy expenditure 162 ; . Because GH secretion is markedly influenced by body weight, and, in particular, adiposity see also below ; , leptin may act as a metabolic signal functionally connecting the adipose tissue with the GH IGF-I axis. Obese mice lacking the ob gene 1128 ; or obese rodents with point and herceptin.

That within the more significant phases of DD, markers of collagen turnover were more elevated in those patients with a history of DHF. This suggests that a more established fibrotic process might explain the development of heart failure in those patients. These data, however, require further analysis, because numbers in these subgroups were small. Effective management of DHF has been impeded to date by a paucity of proven therapies, which possibly reflects a poor understanding of the pathogenesis of this syndrome. The growing evidence that points to a role for abnormal collagen accumulation provides a rationale for the examination of several potential therapeutic approaches in this syndrome. This includes therapies that alter the renin-angiotensin-aldosterone system, which have been shown in several clinical studies to modify the myocardial fibrotic process and improve diastolic function.8, 9, 33, 34 Furthermore, it has been demonstrated that torsemide, a loop diuretic, reduces PICP levels and reverses collagen volume fraction in patients with chronic heart failure.35 In interpreting these data, certain limitations of the present study need to be taken into consideration. First, the present study relied on peripheral markers of collagen turnover without supportive endomyocardial biopsy data or coronary sinus sampling. Second, strict criteria were used to diagnose DHF, with all diagnoses confirmed at the time of presentation by a staff cardiologist. This was done to ensure that the heart failure population was truly representative of DHF syndrome, although in doing so, we clearly excluded those with less severe manifestations of this syndrome. Furthermore, it is also possible that some of the asymptomatic group had subtle symptoms of heart failure, especially those with more severe manifestations of DD. Third, although we included Doppler echocardiographic evidence of DD, we did not perform tissue Doppler, pulmonary venous flow measurements, or invasive confirmation of DD. Fourth, differences in medicines that can attenuate fibrosis across the groups may be a potential limitation to the interpretation of the results; however, because there was greater usage of these medicines in DHF and more severe DD, it may serve to emphasize the role of these markers. Finally, sample sizes were small, and groups were of unequal size when mean levels of collagen turnover markers were compared across the patterns of DD in those with and without DHF, which may result in type II error.
In this study we analyze the binding between heparin and X2 integrin and show that the X I domain has high affinity for fully sulfated heparin oligomers with a length of 12 monosaccharide residues. Our data suggest a conformational regulation of the binding between heparin and the X2 integrin, which demonstrates the role of conformational regulation in integrin binding to a natural, nonproteinous ligand. Furthermore, the strength of the binding between dp12 heparin oligomers and the intact receptor is sufficient to extend the X2 integrin as shown by KIM127 epitope exposure. The X2 integrin contains two chains, each with several domains Fig. 6 ; . The I domain of the chain is the major ligand binding for several protein ligands such as fibrinogen and iC3b. More recent work has identified the I domain as also a binding domain for heparin 3 ; . The I domain may take two different conformations referred to as the "closed" or "open" conformation. As reported earlier the open-conformation X I domain binds strongly to heparin 3 ; , but a characterization of the binding motif in heparin has not been provided. In the present study we provide a more detailed analysis of the interaction between heparin and the X I domain and estimate the strength of the interaction through the ability of the heparin oligomers to inhibit the binding of the openconformation X I domain to iC3b as monitored by SPR. The degree of inhibition was assessed by comparing the response level at the end of the injection phase in the absence or presence or heparin oligomers. However, as equilibrium was not reached for all samples, we also compared the influence of heparin oligomers on the initial on-rate in the binding between the X I domain and iC3b; we found good agreement between the two approaches suggesting that the IC50 values determined from these measurements are a reliable estimation of the strength of binding between the heparin oligomers and the I domain.

Lowry et al. 20 ; . Essentially all of the protein was found to be eluted by Buffer D containing 0.5 M KCl. The method is reproducible, and of the approximately 2.0-2.1 mg of protein recovered, the first 1 ml of eluent usually contains 1.9 mg of protein approximately 0.8% of the applied protein ; . This fraction is referred to as fraction C. Chromatography on control columns, using Sepharose containing no heparin, was performed similarly. Passage of rabbit reticulocyte S-30 through such control columns did not result in the binding of any protein. Previous studies 6 ; have shown that the proteins active in initiation do not interact with such columns, nor with columns containing heparin desulfated sufficiently to be inactive as an inhibitor of protein synthesis [this desulfated heparin still contains greater than two-thirds of the original sulfate groups 5 ; ]. The reticulocyte S-30, passed through either a heparinSepharose column or a control column, was incubated under protein synthetic conditions and the ability of the S-30 to incorporate L- [3H ]leucine into trichloroacetic-acid-insoluble protein was determined as described above. Fraction C was assayed for initiation factor activity by determining its ability to stimulate added mRNA-dependent protein synthesis in the Krebs ascites cell-free systems described above and humalog

The strategy of using antiplatelet therapies might have been rejected as unproved if not also unsafe. The report by Van Damme-Lombaerts et al., 2 to which the correspondents refer, actually supports the use of a more innovative approach to anticoagulant therapy in the hemolyticuremic syndrome. Van Damme-Lombaerts et al. state, "antithrombotic therapy might be beneficial in some selected cases. Indeed, the three major long-term problems arose only in patients from the control [non-heparin] group." With respect to the adverse results attributed to heparin, 3 a review of the data of Vitacco et al. shows 4, not 6, deaths among 10 children treated at presentation with heparin, as compared with 6 among 20 controls.3 Two additional deaths did occur among three patients given heparin, but these three patients constituted a group given heparin only late in the course of their disease owing to clinical deterioration related to the hemolyticuremic syndrome. There was no corresponding control group. ERIC F. GRABOWSKI, M.D., SC.D.
Communication by email or mobile phones can lead to better-prepared doctor visits and reduce the need for visits as well. The integrated-delivery systems are far ahead of the traditional FFS sector in deploying IT.77 It is apparent that the benefits of IT reducing the need for hospital days, doctor visits and diagnostic tests are not in the interest of individual FFS providers.78 Delivery systems that are responsive to cost-conscious consumers would integrate and coordinate the continuum of care at home, the doctor's office, the hospital and the outpatient setting to improve both quality and efficiency. Costs can be reduced when doctors and hospitals are part of the same team with common interests. Care should be delivered in the least-costly appropriate settings, considering total system costs, not just costs and revenues associated with one setting.3 Quality can be increased with smooth transitions and hand-offs between care settings, so that, for example, outpatient providers are well-informed on inpatient care and vice versa ; . Automated tracking should follow actual practice versus the standard, with a message sent to the appropriate provider to inquire about any deviations. Match Resources Used to the Needs of the Population Served. Because the traditional model involves separate payments for each item after the fact, it cannot use a "budget" to plan or to allocate resources. It does not practice some of the elementary principles of good management, such as matching the resources supplied to the needs of the population served, or the services produced. Successful systems could reduce costs by deploying physicians in the numbers and types needed to provide high-quality care to their enrolled populations. Specialty imbalances contribute to the large inefficiencies often observed in American medicine. Too many surgeons can lead to too much surgery, and to surgery done by non-proficient surgeons.79 Cost-conscious systems would select and train physicians and other health professionals for quality and willingness to work in teams, establishing programs to and hyaluronan.

The Company has rapidly moved the SelCIDs from discovery to Phase II clinical trials. This rapid progress has been made possible by Celgene's scientists and academic collaborators, including Professor Miles Houslay's group at the University of Glasgow. Professor Houslay and his team represent the state of the art in understanding and manipulating biochemistries related to PDE-4 enzymes. Following successful completion of a multiple-oral-dose Phase I study in 1998, Celgene announced the launch in 1999 of a Phase II clinical trial of its lead SelCID compound, CDC 801, for the treatment of Crohn's disease. The initial trial is being conducted at Los Angeles' Cedars-Sinai Medical Center by Stephan Targan, M.D and heparin.
After MI 8 ; , differential use may have contributed to outcome differences. Residual confounding may also be due to differences in institutional characteristics and processes of care. For example, do invasive hospitals treat a larger volume of patients with MI? Were patients admitted to hospitals using an invasive approach more likely to have a cardiologist taking care of them than patients at the conservative hospitals? Did invasive hospitals have housestaff, whereas conservative hospitals did not? Did conservative hospitals with on-site catheterization laboratories offer percutaneous coronary angioplasty and coronary artery bypass graft surgery? Was revascularization more complete in those admitted to hospitals favoring an invasive approach? Although the current study is limited by its observational, retrospective design, the authors raise the question of whether there may be benefit with regard to myocardial salvage, in addition to any benefit in prevention of reinfarction and death, with very early catheterization and revascularization in patients with nonST segment elevation MI. Traditional thought has been that if the infarct-related artery is patent in nonST segment elevation MI, benefit from revascularization is due to prevention of recurrent MI in the setting of a critical residual stenosis. However, it may be that early revascularization resulting in a widely patent infarct-related artery may also favorably affect ventricular remodeling after nonQ wave MI and thus have a beneficial effect on outcome. The current study, TIMI-IIIB, VANQWISH and FRISC-II were all performed in the prestent and preGP IIb IIIa inhibitor era. Since then, the use of GP IIb IIIa inhibitors has been shown to have an incremental benefit beyond that of heparin and aspirin in reducing adverse outcomes in patients with nonST segment elevation MI. In the Platelet Glycoprotein IIb IIIa in Unstable Angina: Receptor Suppression Using Integrelin Therapy PURSUIT ; trial, 10, 948 patients with unstable angina or nonQ wave MI were randomized to receive eptifibatide or placebo in addition to heparin and aspirin within 24 h of presentation. Those randomized to eptifibatide had a 10% reduction in the combined incidence of the primary end point of death or MI at days 14.2% vs. 15.7% in the placebo group, p 0.042 ; 9 ; . In the Platelet Receptor inhibition for Ischemic Syndrome Management in Patients Limited by Unstable Signs and Symptoms PRISM-PLUS ; study, 1, 915 patients with unstable angina or nonQ wave MI were randomized to tirofiban plus heparin or heparin alone. All patients received aspirin if not contraindicated. Coronary angiography and angioplasty were performed when indicated after 48 h; 75% underwent revascularization. At seven days, those receiving tirofiban and heparin had a 28% reduction in death, MI or revascularization 12.9% vs. 17.9% ; as compared with those receiving heparin alone 10 ; . The Evaluation of IIb IIIa Platelet Inhibitor for Stenting EPISTENT ; trial evaluated the potential synergy between coronary stents and GP IIb IIIa inhibition and observed that the addition of abciximab improved outcomes as and hydralazine.
