Abstract
5561 Background: Eribulin mesylate is a tubulin inhibitor whose mechanism of action differs from that of other anti-tubulin agents, suppressing microtubule growth without affecting depolymerization, and sequestering tubulin into non-functional aggregates. In NIH:OVCAR-3 human EOC xenograft models, eribulin increased survival and reduced size and number of metastases, with activity superior to paclitaxel. We sought to determine the frequency of objective response to treatment with eribulin in patients (pts) with PR-EOC. Methods: Pts with PR-EOC, fallopian tube or peritoneal cancer (progression-free interval from last platinum-based therapy < 6 months), measurable disease, < 2 prior cytotoxic regimens, ECOG performance status 0–1, and adequate organ function were eligible. Treatment: eribulin 1.4 mg/m2 over 15 minutes IV days 1 and 8, every 21 days. Response assessed by CT for RECIST every other cycle. Results: 36 pts (median age 61, range 38–80; median platinum-free interval 3 months, range 0.1–5.9; all having received platinum-taxane first-line treatment) enrolled. 35 are evaluable for response (1 pt off-study for unrelated myocardial infarction in cycle 1). Two pts achieved partial responses (PR-5.7%), with response durations of 84 days and 128 days. Time to PR was 2.8 months in both. >50% decrease in CA125 for more than two measurements was observed in 3/31 CA125-evaluable pts. 16/35 (46%) had stable disease as best response. Median progression-free survival was 2 months (range 1–7 months). Per patient, at least possibly-related grade 3–4 toxicities were: neutropenia 44%, leucopenia 31%, anemia 3%, lymphopenia 3%, febrile neutropenia 3%, muscle weakness 3%, hypophosphatemia 3%, hypokalemia 6%, infection 6%, thrombosis 6%. Conclusions: Eribulin has minimal activity in PR-EOC with objective response observed in only 5.7% of pts. Time to objective response was nearly 3 months. Median PFS was 2 months. Activity of eribulin in platinum-sensitive patients is being studied in a separate phase II cohort. [Table: see text]

Abstract
Lead does not fulfill any physiological function in the human body. It is generally accepted that the blood lead level (BLL) is the best exposure index, as there is an excellent correlation between the actual exposure of the individual and the concentration of lead in blood. In Uruguay, lead contamination becomes a matter of public concern in 2001, giving rise to a sensitization in the population, which in many cases brought about a change in hygienic and dietary habits of the children. In 2004, after the leaded gasoline phasing out process in Uruguay was completed, we studied non-exposed children to correlate BLL with variables such as age, sex, area of residence, and available environmental lead data and compared these results with those from our similar screening studies 10years ago. The main result of this comparison is that BLL from children in our country had a significant decrease between 1994 and 2004.

Abstract
19649 Background: Quality of life (QoL) is an important endpoint measure in clinical cancer trials. We evaluated prospectively the effects of two cycles of chemotherapy (CT) on QoL and the relationship between QoL and survival in advanced NSCLC patients (pts). Methods: The short-form of the SF36 was completed prior to and after 2 cycles of chemotherapy. An ITT analysis was used; a score of 0 was assigned to those who died and the last observation was carried forward for those with missing data. Results: Fifty-nine pts consented to participate and pre-chemo evaluation was available for 58 pts. Of these 58, only 40 pts completed the study (4 died, 14 did not complete the post evaluation). There were 26M: 32F with a median age of 61±11 years. Fifty pts (86%) were stage 3B (pl. eff)/4 and 50pts (86%) were PS 0–1. Overall QoL decreased significantly from 100±19 to 91±36 after two cycles of chemotherapy (p=0.03). This decline was attributed to a significant decrease in the physical health subscale (p=0.001), with 36% of pts reporting a clinically significant decline of =2. No change in the mental health subscale was observed. The symptoms that had the most profound negative impact on the physical health subscale were: ‘easily get sick’ (54%), ‘increased pain’ (30%) and ‘decreased activities’ (27%). SD+PR occurred in 36 (62%) pts, whereas 22 (38%) pts had PD after two cycles of chemotherapy. No correlation was found between response to chemo and change in QoL. The median survival (15±6.8mo), of pts whose QoL score remained stable or improved (n=36) was significantly better than those (n=22) whose QoL decreased (9±3.2 mo) (p=0.01). Conclusions: QoL decreased following chemotherapy due to a decrease in the physical health subscale. Further studies are required to determine if training can improve physical health and thus QoL and survival. No significant financial relationships to disclose.

Abstract
Cardiac myosin binding protein-C (cMyBP-C) is a thick filament-associated protein that binds tightly to myosin and has a potential role for modulating myocardial contraction. We tested the hypothesis that cMyBP-C 1) contributes to the enhanced in vivo contractile state following beta-adrenergic stimulation and 2) is necessary for myocardial adaptation to chronic increases in afterload. In vivo pressure-volume relations demonstrated that left ventricular (LV) systolic and diastolic function were compromised under basal conditions in cMyBP-C(-/-) compared with WT mice. Moreover, whereas beta-adrenergic treatment significantly improved ejection fraction, peak elastance, and the time to peak elastance in WT mice, these functional indexes remained unchanged in cMyBP-C(-/-) mice. Morphological and functional changes were measured through echocardiography in anesthetized mice following 5 wk of aortic banding. Adaptation to pressure overload was diminished in cMyBP-C(-/-) mice as characterized by a lack of an increase in posterior wall thickness, increased LV diameter, deterioration of fractional shortening, and prolonged isovolumic relaxation time. These results suggest that the absence of cMyBP-C significantly diminishes in vivo LV function and markedly attenuates the increase in LV contractility following beta-adrenergic stimulation or adaptation to pressure overload.

Abstract
Peginterferon-alpha plus ribavirin is the most effective therapy for chronic hepatitis C. This study was designed to evaluate the effect of peginterferon alpha-2a (40 kDa) plus ribavirin on sustained virological response (SVR) when administered for 24 vs 48 weeks in genotype 1 naïve patients. One hundred and seventeen patients were enrolled in this controlled trial. Genotype 1 patients were randomized to 24 weeks treatment vs 48 weeks treatment. Genotype non-1 patients received 24 weeks treatment as an observational group. Outcomes were SVR (defined by hepatitis C virus-RNA-negative at week 24 of follow-up) and tolerability across the study period. The end-of-treatment response was 59% for genotype 1 (24 weeks treatment), 80% for genotype 1 (48 weeks treatment) and 92% for genotype non-1 (24 weeks treatment). The end-of-follow-up response was 19% (95% confidence interval (CI): 7.2-36.4) (genotype 1, 24 weeks) and 48% (95% CI: 30.2-66.9; P = 0.0175) (genotype 1, 48 weeks). Among genotype non-1, SVR was 76% (95% CI: 62.3-86.5). There were no unexpected adverse events. Almost half of the genotype 1 patients achieved an SVR after 48 weeks treatment with peginterferon alpha-2a (40 kDa) and low-dose ribavirin and confirmed that they should be treated for 48 weeks. Safety profile was acceptable.

Abstract
Studies of intrauterine human cytomegalovirus (CMV) infection have shown suppressed replication in the decidua and placenta of strongly seropositive women. Biopsy specimens often contain CMV virion glycoprotein B and DNA in syncytiotrophoblasts and villus core macrophages without productive infection. Focal replication occurs in placentas of women with low to moderate neutralizing antibody titres. Infected cytotrophoblasts downregulate key adhesion and immune molecules required for invasiveness and maternal immune tolerance and reduce matrix metalloproteinase-9 protein and activity, impairing degradation of the extracellular matrix. Here, we used flow cytometry and quantitative RT-PCR analyses to quantify differentiation molecules expressed in freshly isolated cytotrophoblasts purified from placentas at term and differentiating cells infected in vitro with VR1814, a pathogenic clinical strain. Cell surface proteins including E-cadherin, VE-cadherin, HLA-G, and CMV receptors--epidermal growth factor receptor and integrins beta1 and alphavbeta3--were expressed on purified cells, as were integrins alpha9 and beta6, which were not previously studied. Infected cytotrophoblasts dysregulate the levels of particular cell-matrix and cell-cell adhesion proteins and their transcripts. CMV replication in late gestation placentas with considerable reserves could deplete cytotrophoblast progenitors, thereby impairing syncytiotrophoblast development and increasing the risk of virus transmission to fetal blood vessels.
