Abstract
Abstract
Background
Studies performed in multiple preclinical models support the contribution of the Ca2+-dependent cysteine proteases calpains to ventricular remodelling and heart failure (HF). However, pharmacological calpain inhibition has not yet been tested in patients with HF mainly due to the limitations of available inhibitors.
Purpose
To determine the effect of NPO-2270 (NPO), a new ketoamide derivative calpain inhibitor, in a mouse model of pressure-overload and compare its effectiveness with that of enalapril.
Methods
C57BL6 mice were subjected to transverse aortic constriction (TAC) for 4 weeks. Mice were randomised to receive orally administered NPO or enalapril at the dose of 10 mg/kg/day once a day, or vehicle, starting at day 7 after TAC surgery. The combination of both drugs and the effect of NPO starting 1 day after surgery were tested in additional TAC mice. Echocardiographic data, markers of hypertrophy, fibrosis, calpain activity and cleavage of calpain substrates were measured at different time points.
Results
TAC increased calpain-1 and -2 expression and activity. Administration of NPO and enalapril prevented the progression of hypertrophy and interstitial fibrosis induced by TAC with no statistically significant differences between the two treatments. However, ongoing ventricular dysfunction was less severe in the NPO group than in the enalapril group (27% of LVEF reduction in control group, 6% in NPO group and 16% in the enalapril group after TAC, P=0.024 between NPO and enalapril groups). The combined treatment or the administration of NPO from the first day after TAC surgery was not superior to NPO alone starting 7 days after TAC. These differences in LVEF correlated with better preservation of cadherin-based cell adhesion complex in mice treated with NPO-2270. No adverse effects associated with long-term NPO administration were observed in a sham group.
Conclusions
The new calpain inhibitor NPO-2270 prevents the development of hypertrophy and fibrosis with similar efficacy than enalapril but prevents cardiac dysfunction more effectively in a preclinical model of pressure overload when given orally at equivalent doses.

Abstract
Snakebite causes 421.000-1.200.000 poisonings per year due to and hematotoxicity, neurotoxicity y vasculotoxicity. Ophthalmological manifestations secondary to snake bites are rare. If the snake belongs to the Viperidae family, the most frequent ophthalmologic manifestations are macular infarction, chronic open-angle glaucoma, and retinal or vitreous hemorrhage. Central retinal artery occlusion is an extremely rare ocular complication. We report the case of a 30-year-old patient, who consulted due to poor vision in her left eye weeks after suffering a snake bite (Bothrops atrox) in her left lower limb. The diagnosis was a central retinal artery occlusion in the left eye with abnormal findings in the ophthalmological physical examination and in complementary retinal and neuro-ophthalmological tests.

Abstract
Abstract
Introduction
Somatic mutations in hematopoietic cells are associated with age and have been associated with higher mortality in apparently healthy adults, especially due to atherosclerotic disease. In animal models, somatic mutations are associated with atherosclerosis progression and myocardial dysfunction, especially when gene TET2 is affected. Preliminary clinical data, referred to ischemic heart failure (HF), have associate the presence of these acquired mutations with impaired prognosis.
Purpose
To study the prevalence of somatic mutations in patients with heart failure with reduced ejection fraction (HFrEF) and their impact on long-term prognosis.
Methods
We studied a cohort of elderly patients (more than 60 years old) hospitalized with HFrEF (LVEF<45%). The presence of somatic mutations was assessed using next generation sequencing (Illumina HiSeq 2500), with a mutated allelic fraction of at least 2% and a panel of 55 genes related with clonal hematopoiesis. Patients were followed-up for a median of three years. The study endpoint was a composite of death or readmission for worsening HF. Kaplan-Meier analysis (log-rank test) and Cox proportional hazards regression models were performed adjusting for age, sex and LVEF.
Results
A total of 62 patients (46 males (74.2%), age 74±7.5 years) with HFrEF (LVEF 29.7±7.8%) were enrolled in the study. The ischemic etiology was present in 54% of patients. Somatic mutations in Dnmt3a or Tet2 were present in 11 patients (17.7%). No differences existed in baseline characteristics except for a higher prevalence of atrial fibrillation in patients with somatic mutations (70% vs. 40%, p=0.007). During the follow-up period, 40 patients (64.5%) died and 38 (61.3%) had HF re-admission. The KM survival analysis for the combined event is shown in Figure 1. Compared with patients without somatic mutations and after adjusting for covariates, there was an increased risk of adverse outcomes when the somatic mutations were present (HR 3.6, 95% CI [1.6, 7.8], p=0.0014). This results remains considering death as a competing risk (Gray's test p=0.0097) and adjusting for covariates (HR = 2.21 95% CI [0.98, 5], p=0.0556).
Conclusions
Somatic mutation are present in patients with HFrEF and determine a higher risk of adverse events in the follow-up. Further studies are needed to assess the clinical implications of these findings.

Abstract
Saline-alkaline lakes of the East African Rift are known to have an extremely high primary production supporting a potent carbon cycle. To date, a full description of carbon pools in these lakes is still missing. More specifically, there is not detailed information on the quality of dissolved organic matter (DOM), the main carbon energy source for heterotrophs prokaryotes. We report the first exhaustive description of DOM molecular properties in the water column of a meromictic saline-alkaline lake of the East African Rift. DOM availability, fate and origin were studied either quantitatively, in terms of dissolved organic carbon (DOC) and nitrogen (DON) or qualitatively, in terms of optical properties (absorbance) and molecular characterization of solid-phase extracted DOM (SPE-DOM) through negative electrospray ionization Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). DOM availability was high (DOC ∼ 8.1 mM in surface waters) and meromixis imprinted a severe quantitative and qualitative change on DOM pool. At the surface, DOM was rich in aliphatic and moderately in aromatic molecules and thus mirroring autochthonous microbial production together with photodegradation. At the bottom changes were extreme: DOC increased up to 5 times (up to 50 mM) and, molecular signature drifted to saturated, reduced and non-aromatic DOM suggesting intense microbial activity within organic sediments. At the chemocline, DOC was retained indicating that this interface is a highly reactive layer in terms of DOM processing. These findings underline that saline-alkaline lakes of the East African Rift are carbon processing hot spots and their investigation may broaden our understanding of carbon cycling in inland waters at large.

Abstract
The objective of this study was to quantify the magnitude of iron deficiency in the postoperative period after open aortic surgery. This was a prospective observational study in 55 consecutive patients. Blood samples were obtained on postoperative days 1, 2, 4, 30, and 45, and the parameters determined were the following: iron, transferrin, transferrin saturation index, transferrin-soluble receptor, ferritin, red cell count, hemoglobin, hematocrit, serum C-reactive protein, fibrinogen, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and number of blood units transfused. We performed statistical ANOVA test for repetitive measurements (lower bound) in regard to its basal level. Iron deficiency and its parameters reached the maximum at 48 hours postoperatively (iron: 18.92 g/dL and transferrin saturation index: 11.1%) (P <.05). There was not a complete recovery after 45 days (iron: 51.23 g/dL and transferrin saturation index: 18.0%) (P <.05). A similar evolution was observed in the other measured parameters (red cell count: 3.5 x 106/L.; hemoglobin: 10.4 g/dL; hematocrit: 30.7%) (P <.005), none affecting the values of concentration or volume (P <.05). Transferrin-soluble receptors, normal at first, were increased at postoperative days 30 and 45 (2.7 and 2.4 mg/dL respectively, P <.005). After open aortic surgery there is an important acute-phase reaction, a dramatic iron deficiency, and a lack of its transporters until the 45th analyzed day. The elevation of transferrin-soluble receptors in the 4th and 6th weeks denotes a necessity of iron supplementation for a correct development of the immature hematic cells since blood parameters do not reach normal levels in the 6th postoperative week.

Abstract
The main objective of the present work was to develop and validate a multicompound method to measure soluble milk glycans (SMGs) in biological fluids such as serum. An ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method for the identification and quantification of the following SMGs and their precursors 2'-fucosyllactose, 3'-sialyllactose, 6'-sialyllactose, lacto-N-neotetraose, N-acetylneuraminic acid, fucose, lactose and glucose in rat serum samples was set up. These analytes were separated in an Acquity UPLC BEH Amide column using acetonitrile-water gradient with ammonia as additive, in a 10 min run, and were detected and quantified using a triple quadrupole (QqQ) mass spectrometer. The mass spectrometric conditions in negative electrospray ionization mode (ESI-) were individually optimized for each analyte to obtain maximum sensitivity in the Selected Reaction Monitoring (SRM) mode. Selection of two specific fragmentation reactions for each compound allowed simultaneous quantification and identification in one run, ensuring a high specificity of the method. The limits of detection (LODs) ranged from 5 to 70 ng mL(-1) and the limits of quantification (LOQs) from 20 to 200 ng mL(-1). The inter- and intra-day variability was lower than 15% and the recoveries ranged from 85% to 115%. A biological application of the method was also described, specifically the time-course of SMGs in rat serum after an oral challenge.

Abstract
BACKGROUND Organ confined prostate cancer (PCa) can be cured by radical retropubic prostatectomy (RRP); however, some tumors will still recur. Current tools fail to identify patients at risk of recurrence. Glutathione-S-transferases (GSTs) are involved in the metabolism of carcinogens, hormones and drugs. Thus, genetic polymorphisms that modify the GST activities may modify the risk of PCa recurrence. METHODS We retrospectively recruited Argentine PCa patients treated with RRP to study the association between GST polymorphisms and PCa biochemical relapse after RRP. We genotyped germline DNA in 105 patients for: GSTP1 c.313A>G (p.105 Ile>Val, rs1695) by PCR-RFLP; and GSTT1 null and GSTM1 null polymorphisms by multiplex PCR. Kaplan-Meier curves and Cox proportional hazard models were used to evaluate these associations. RESULTS Patients with GSTP1 c.313GG genotype showed shorter biochemical relapse-free survival (BRFS) (P = 0.003) and higher risk for recurrence in unadjusted (Hazard ratio (HR) = 3.16, 95% confidence interval (95% CI) = 1.41-7.06, P = 0.005) and multivariate models (HR = 3.01, 95% CI = 1.13-8.02, P = 0.028). We did not find significant associations for GSTT1 and GSTM1 genotypes. In addition, we found shorter BRFS (P = 0.010) and increased risk for recurrence for patients having two or more risk alleles when we combined the genotypes of the three GSTs in multivariate models (HR = 3.06, 95% CI = 1.20-7.80, P = 0.019). CONCLUSIONS Our results give support to the implementation of GSTs genotyping for personalized therapies as a novel alternative for PCa management for patients who undergo RRP. To the best of our knowledge, this is the first study that examined GST polymorphisms in PCa progression in Argentine men. Replication of our findings in larger cohort is warranted.

Abstract
The metastatic cascade and colonization remains a major challenge in clinical therapeutics. The formation of metastasis has many rate limiting steps. The expression of metastases initiation genes in primary tumors is driven by the need for cell motility, invasiveness, handling the shear stress in the vasculature and lymphatic circulation, and the survival and persistent growth in the distant organ. However, the expression of the progression genes in the primary tumors has a more complex basis. These metastasis-prone genes support primary tumor growth through one particular effect, whereas they enhance distant metastasis through another effect. The boundaries between metastasis initiation and metastasis progression genes are not rigid. In this review, we examine novel gene signatures identified in metastases, address key inflammatory factors mastering homing selection, gain further mechanistic insights into cell plasticity and evaluate the role of microRNAs. Moreover, we also describe the recent progress in developing nanoparticle imaging substantiating a promising theranostic platform for future cancer diagnostics and treatment, and assess the relevance of the bioinformatic analysis of metastasis-related proteins with an eye toward the metastatic niche. All these tools will provide valuable biological information of the progression of the disease, helping find potential therapeutic targets and improving surgical procedures. In a near future the understanding of the molecular mechanisms in tumor dissemination will be pivotal for the translation of these methods to the clinic and will help to overcome the barriers in clinical therapy of metastases.

Abstract
It is currently estimated that inflammatory responses are linked to 15-20% of all deaths from cancer worldwide. Although many studies point to an important role of inflammation in prostate growth, the contribution of inflammation to castration-resistant prostate cancer is not completely understood. The presence of inflammatory mediators in tumor microenvironment raises the question whether genetic events that participate in cancer development and progression are responsible for the inflammatory milieu inside and surrounding tumors. Activated oncogenes, cytokines, chemokines and their receptors, sustained oxidative stress and antioxidant imbalance share the capacity to orchestrate these pro-inflammatory programs; however, the diversity of the inflammatory cell components will determine the final response in the prostate tissue. These observations give rise to the concept that early genetic events generate an inflammatory microenvironment promoting prostate cancer progression and creating a continuous loop that stimulates a more aggressive stage. It is imperative to dissect the molecular pathologic mechanism of inflammation involved in the generation of the castration-resistant phenotype in prostate cancer. Here, we present a hypothesis where molecular signaling triggered by inflammatory mediators may evolve in prostate cancer progression. Thus, treatment of chronic inflammation may represent an important therapeutic target in advanced prostate cancer.

Abstract
The most commonly used drugs against pain act by inhibiting the cyclooxygenases (COXs). Metamizol (dipyrone) inhibits the COXs and is widely used in Europe and Latin America as a non-opioid analgesic. One target of metamizol and other non-opioid analgesics is the periaqueductal grey matter (PAG), where they trigger descending inhibition of spinal nociceptive transmission. Also, cannabinoids exert an analgesic action at several structures in the peripheral and central nervous system, including the PAG. The present study investigates whether the antinociceptive action of metamizol in the lateral-ventrolateral (LVL) PAG during inflammation is related to endocannabinoids. In anaesthetized rats, unitary action potentials were recorded from spinal nociceptive neurons with receptive fields in the ipsilateral hind paw. Inflammation of the paw induced neuronal hyperexcitability, which was attenuated by intra-LVL-PAG microinjection of metamizol either at the beginning of inflammation or when hyperexcitability was fully established. In both cases, the antinociceptive effect of metamizol was reduced by a microinjection of AM251, an antagonist at the CB1 cannabinoid receptor, either into the LVL-PAG or into the rostral ventromedial medulla (RVM). The RVM is a downstream structure that funnels PAG-derived descending inhibition into the spinal cord. These results show that endocannabinoids and their CB1 receptor (1) contribute at the LVL-PAG to the antinociceptive effects of metamizol, and possibly other non-opioid analgesics; and (2) participate in the PAG-derived activation of RVM descending antinociceptive influences.

Abstract
Pancreatic cancer is characterized by aggressive growth and resistance to treatment. Identification of unique biomarkers for diagnosis and prognosis is important for treatment of this disease. We investigated the expression patterns of mucin 1 (MUC1), mucin 2 (MUC2) and cytokeratin 17 (CK17) in both normal tissues and metastatic adenocarcinomas using immunohistochemistry (IHC). We have shown that MUC1 (pan-epithelial membrane mucin), MUC2 (intestinal-type secretory mucin) and CK17 can be used as a panel of markers to distinguish collectively pancreatobiliary carcinoma from other primary site carcinomas. Tumors originating in the pancreatobiliary system showed an expression pattern of MUC1 (+), MUC2 (-) and CK17 (+). By contrast, tumors arising from the colorectal region were MUC1 (-), MUC2 (+) and CK17 (-), while tumors originating from non-pancreatobiliary system tissue expressed a MUC1 (+), MUC2 (-) and CK17 (-) profile. More importantly, the MUC1 (+), MUC2 (-) and CK17 (+) result showed greater sensitivity than CA19-9 by IHC, which is the currently accepted and widely used pancreatic tumor marker for diagnosing pancreatic cancer. Thirteen of 51 cases (25%) of pancreatobiliary adenocarcinomas with the pattern MUC1 (+), MUC2 (-) and CK17 (+) showed no immunoreactivity for CA19-9, while 34/51 (67%) cases having MUC1 (+), MUC2 (-) and CK17 (+) were correlated with positive CA19-9 staining. Our data support using an antibody panel of MUC1, MUC2 and CK17 to enhance current methods for pancreatic cancer diagnosis by identifying specifically the primary tissue of origin.

Abstract
e11509 Background: Docetaxel/cyclophosphamide has demonstrated superior disease free and overall survival compared to doxorubicin/cyclophosphamide in the treatment of early stage breast cancer with an acceptable safety profile, with grade (G) 3/4 neutropenia of 61% and no cardiotoxicity. Nanoparticle albumin-bound (nabtm)-paclitaxel (nab-P) is a novel formulation with demonstrated superior efficacy to conventional paclitaxel (P) in treatment of metastatic breast cancer with a comparable safety profile. We therefore conducted a multicenter phase II pilot trial of weekly nab-P/cyclophosphamide to assess the safety and tolerability of this combination in early stage breast cancer. Methods: Eligibility: T1–4pN0–3M0, ECOG PS 0–2, normal organ function, normal LVEF for pts receiving trastuzumab (T). Treatment consisted of nab-P 100 mg/m2 day (D) 1, 8, 15 with cyclophosphamide (C) 600 mg/m2 D1 q 21 days x 4 cycles. T was given in IHC 3+ or FISH HER2+ pts with an 8 mg/kg loading dose followed by 6mg/kg q21D x 52 weeks. Results: 63 pts enrolled from April 2008 through September 2008; 33 pts are evaluable for safety with a median of 2 cycles. Baseline characteristics: median age 57 years (range 33–76); ECOG PS 0–94%, T1-T2 tumors - 100%, node negative 61%, hormone receptor negative 33%, HER 2+ 15%, triple negative 27%, ductal histology 73%, premenopausal 37 %. nab-P dose modifications occurred in 10 of 33 pts with nab-P reductions in 2 pts: 1 each due to G3 neutropenia- cycle 2 and G3 neuropathy- cycle 4. All 8 nab-P treatment delays were due to G3 neutropenia at D15. G3/4 neutropenia was present in 30% with only 1 G4 episode. 1 pt utilized myeloid colony stimulating factors. There were no G3/4 non-heme toxicities present in > 5 % of pts and no LVEF declines in pts receiving T. 17 pts remain on study with 3 pts receiving T. Conclusions: The combination of weekly nab-P with cyclophosphamide is feasible and well tolerated with an acceptable safety profile as adjuvant therapy for early stage breast cancer. The addition of T to this combination did not create any safety concerns. Full safety data for the 63 pts will be updated at the time of the meeting. [Table: see text]

Abstract
The role of oxidative stress in prostate cancer has been increasingly recognised. Acute and chronic inflammations generate reactive oxygen species that result in damage to cellular structures. Haeme oxygenase-1 (HO-1) has cytoprotective effects against oxidative damage. We hypothesise that modulation of HO-1 expression may be involved in the process of prostate carcinogenesis and prostate cancer progression. We thus studied HO-1 expression and localisation in 85 samples of organ-confined primary prostate cancer obtained via radical prostatectomy (Gleason grades 4–9) and in 39 specimens of benign prostatic hyperplasia (BPH). We assessed HO-1 expression by immunohistochemical staining. No significant difference was observed in the cytoplasmic positive reactivity among tumours (84%), non-neoplastic surrounding parenchyma (89%), or BPH samples (87%) (P=0.53). Haeme oxygenase-1 immunostaining was detected in the nuclei of prostate cancer cells in 55 of 85 (65%) patients but less often in non-neoplastic surrounding parenchyma (30 of 85, 35%) or in BPH (9 of 39, 23%) (P<0.0001). Immunocytochemical and western blot analysis showed HO-1 only in the cytoplasmic compartment of PC3 and LNCaP prostate cancer cell lines. Treatment with hemin, a well-known specific inducer of HO-1, led to clear nuclear localisation of HO-1 in both cell lines and highly induced HO-1 expression in both cellular compartments. These findings have demonstrated, for the first time, that HO-1 expression and nuclear localisation can define a new subgroup of prostate cancer primary tumours and that the modulation of HO-1 expression and its nuclear translocation could represent new avenues for therapy.

Abstract
18133 Background: In a previously reported phase II trial bevacizumab (B) was used as maintenance therapy following induction with irinotecan (I), carboplatin (C) and radiotherapy (RT) in patients (pts) with limited-stage small-cell lung cancer (LS-SCLC). 1-year progression- free survival (PFS) and overall survival (OS) were 53% and 70%, respectively. In the present multicenter community-based trial B is given with induction chemoradiotherapy and as maintenance therapy. Methods: The primary endpoint is to assess the median PFS. Eligibility criteria: newly diagnosed LS-SCLC, measurable disease, ECOG PS 0–1, and informed consent. Exclusion criteria: hemoptysis and therapeutic anticoagulation. Treatment: I 60mg/m2 IV D1, 8, 15, C AUC=4 IV D1, and B 10 mg/kg IV D1 and 15 every 28D. Pts received concurrent RT to 61.2 Gy starting with the 3rd cycle, and were restaged every 8 weeks. If no progressive disease (PD) or excessive toxicity after 4 cycles, pts received B x 6 months. Prophylactic cranial irradiation was used at M.D. discretion. This 2-stage trial was designed to achieve a 40% improvement in historical median PFS of 12–14 months. Results: 20 pts were enrolled from 4/06 to 12/06 (trial ongoing, n=50 planned). Data are available for 14 pts in this analysis. Baseline features: median age 64 years; male/female, 21%/79%; and ECOG PS 0/1, 64%/36%. The objective response rate was 78% (95% CI 45%-94%) - all partial responses. No pt had PD. 7 pts were not evaluable: too early, 5 pts; off study (toxic megacolon, 1 pt; intercurrent illness, 1 pt). With a median follow-up of 5 months, the median PFS has not been reached. Grade (G) 3/4 non-hematologic toxicity with induction occurring in more than 2 pts: diarrhea (29%) and esophagitis, fatigue, pain (21% each). G3/4 hematologic toxicity: leukopenia (21%), neutropenia (14%), and thrombocytopenia (43%). There have been 2 G3/4 bleeding events with induction: suspected tracheoesophageal fistula with death (possibly treatment-related), 1 pt; and hematochezia, unrelated, 1 pt. Conclusions: This trial continues to be closely monitored for safety. Further accrual and longer follow-up are necessary to assess if B can be safely combined with chemoradiotherapy and improve efficacy. No significant financial relationships to disclose.

Abstract
18091 Background: Vinflunine (VFL) is a novel microtubule inhibitor of the vinca alkaloid class which has demonstrated significant preclinical activity in a small cell lung cancer (SCLC) model and antitumor activity in several other tumor types. This multicenter community- based trial was designed to examine the role of VFL in patients (pts) with relapsed SCLC. Methods: The primary endpoint is objective response rate (ORR). Eligibility criteria: previously treated SCLC (sensitive or refractory relapsed pts; limited to 1 prior platinum or non-platinum therapy for limited- or extensive-stage disease), ECOG PS 0–2, measurable disease, and informed consent. Treatment: VFL 320 mg/m2 IV over 20 minutes day 1 every 21 days for up to 6 cycles. Pts were restaged every 6 weeks. This 2-stage trial was designed to achieve a 20% ORR in platinum-sensitive pts (per RECIST criteria). Results: 29 pts were enrolled from 3/06 to 12/06 (trial ongoing, n=41 planned). Data are available for 16 pts in this analysis. Baseline characteristics: median age 64 years; male/female, 63%/37%; ECOG PS 0/1/2, 25%/50%/25%; and sensitive relapse, 50%. 3 partial response have been observed (ORR 19%, 95% CI 4%-46%). 3 pts (19%) had stable disease and 7 pts (44%) had progressive disease. 3 pts were not evaluable due to: treatment-related toxicity (sepsis; constipation); declining PS, 1 pt each. With a median follow-up of 5 months, the median progression-free survival and overall survival are 1.7 months and 3.6 months, respectively. Grade (G) 3/4 non-hematologic toxicity occurring in more than 1 pt: constipation, dyspnea, fatigue, and hyponatremia (13% each). G3/4 hematologic toxicity: leukopenia (44%), neutropenia (38%), and thrombocytopenia (6%). There have been no treatment-related deaths. Conclusions: VFL appears active as second-line treatment for SCLC. Additional assessment of myelosuppression is needed to better assess VFL’s role. Completion of accrual is anticipated by 4/07. No significant financial relationships to disclose.

Abstract
18100 Background: Preoperative chemotherapy may improve outcomes for patients (pts) with resectable non-small cell lung cancer (NSCLC) compared with surgery alone. This multicenter community-based phase II trial examined the role of preoperative gemcitabine (G) and docetaxel (D) in pts with resectable NSCLC. Methods: The primary endpoint was to assess the pathologic response rate of G/D in pts with potentially resectable clinical stages IB, II, and selected III NSCLC [T3N1, T1–3N2 (1 nodal station = 2 cm), T4N0, T4N1 excluding vascular, tracheal, esophageal, vertebral disease, or malignant effusions]. Additional eligibility criteria: measurable disease, ECOG PS 0–1, and informed consent. Treatment: G 1,000 mg/m2 and D 30 mg/m2 days 1, 8 every 21 days x 3 cycles. Pts were restaged after treatment and resected 3–6 weeks later. If pts were inoperable, had incomplete resections, or N2 disease, D 20 mg/m2, carboplatin AUC=1.5 weekly x 7, and radiation to 63 Gy were administered. Analysis was by intent to treat. Results: Between April 2004 and September 2005, 75 pts were enrolled. Median age was 62 years. 92% of planned preoperative therapy was administered and 38 pts (51%) underwent resection. The clinical objective response rate was 30% (95% CI 20%-42%). No pathological complete responses were observed. 26 pts went on to receive chemoradiotherapy. Median progression-free survival was 9.8 months (95% CI 5.9–13.9). Median overall survival was 18 months (95% CI 14.8- 21.3). 71% of pts were alive at 1 year. Grade 3/4 hematologic toxicity with preoperative therapy included neutropenia (28%), anemia (4%), and thrombocytopenia (7%). Grade 3/4 non-hematologic toxicity was limited. Conclusions: G/D is a well tolerated preoperative regimen for pts with resectable NSCLC, however did not result in pathologic complete responses. There is no suggestion that G/D is more active than other tested combined modality regimens. The role of preoperative therapy in NSCLC remains undefined. Additional studies comparing preoperative and adjuvant treatment are warranted. No significant financial relationships to disclose.

Abstract
7188 Background: Concurrent CRT improves outcomes for pts with unresectable stage III NSCLC compared with radiation (RT) alone. The EGFR inhibitor G benefits select pts with advanced NSCLC. This multicenter community phase II trial examined the role of CRT followed by G for pts with unresectable stage III NSCLC. Methods: Theprimary endpoint was 2-year overall survival (OS) in pts with unresectable stage IIIA/B NSCLC (effusions, N3 mediastinal nodes >4 cm excluded) treated with CRT followed by G. Induction(I) treatment (tx): docetaxel (D) 40 mg/m2 IV and gemcitabine 800 mg/m2 IV D1, 8 Q 21D × 3 cycles. Pts without progressive disease (PD) began: D 20 mg/m2 IV and carboplatin (C) AUC = 1.5 IV weekly × 6 and RT 61.2 Gy, 1.8-Gy M-F weekly × 7 (starting 1 week prior to D/C). If no PD, pts received G 250 mg PO daily × 2 years or until PD. Eligibility:measurable disease, ECOG PS 0–1, informed consent. Intent to treat analysis. Results: One-hundred three pts were enrolled from 7/03 to 4/05. Baseline features: medianage 60 years (37–79); male/female 54%/46%; ECOG PS 0/1:26%/74%; adenocarcinoma (26%), squamous (32%), large cell (28%), mixed/not specified (14%); IIIA/B (46%/54%). Grade 3/4 toxicities were limited to ≤ 8% except for neutropenia (17%, during I) - with notx-related deaths. Complete/partial responses after I were seen in 1 pt/34 pts, respectively, for an overall response rate (RR) of 34% (95% CI 26%-44%). Forty-two pts (41%) had stable disease (SD) and 12% had PD (9 pts were unevaluable.) Seventy-four pts (72%) received D/C/RT which resulted in an overall RR of 44% (95% CI 35%-54%). Fifteen percent had SD. Fifty-six pts (54%) received G for a median of 28 weeks (1–107). Median PFS and OS are 9.9 and 15 months, respectively. After a median follow-up of 19 months, actuarial 1- and 2-year progression-free survival (PFS) is 41% and 12%, respectively. 1- and 2-year OS rates are 64% and 21%, respectively. Subset analyses by smoking, gender, histology, and stage are in progress. Conclusions: Maintenance G following CRT in unresectable NSCLC does not appear to improve survival. It is possible that further analysis may suggest a role for G in selected pts. [Table: see text]

Abstract
BACKGROUND AND AIMS Control of cell proliferation is important for cancer prevention since cell proliferation has an essential role in carcinogenesis. In rodent carcinogenesis models, antioxidant agents suppress carcinogen-induced cellular hyper proliferation in the target organs. Strict control of cell division is an essential process to ensure that DNA synthesis and mitotic division are accurately and coordinately executed. We studied the interplay between cell cycle and heme oxygenase-1 (HO-1) and the effect of the acetylsalicylic acid (ASA) in hepatic carcinogenesis. METHODS Male CF1 mice pre-treated with dietary p-dimethylaminoazobenzene (DAB; 0.5%, w/w) were fed with ASA (0.16%, w/w). We investigated the hepatic expression of cyclin D1, cyclin E, Cdk2, Cdk4, p21, p27, p53; the level of bcl-2, an antiapoptotic protein and of heme oxygenase-1 (HO-1), a marker of oxidative stress, by Western blot analysis. RESULTS The treatment with ASA produced an important attenuation in the induction of cyclin E and cyclin D1 provoked by DAB. p21 and p27 levels were increased when animals received both drugs. The administration of ASA to DAB treated animals induced Cdk2 (29%). HO-1 induction (65%) provoked by DAB was diminished by ASA administration reaching lower induction levels (23%). CONCLUSION The deregulation of cyclin/CDK expression and the up-regulation of p21 and p27 with the administration of ASA, post-treatment of the carcinogen administration, would block the pass through out to the G0/G1 check point to permit the cells to repair their DNA and HO-1 protected the liver from reactive oxygen species produced from DAB.

Abstract
AIMS Although peak exercise echocardiography has been reported for both bicycle and treadmill exercise and has shown higher sensitivity than post-exercise imaging, little is known about its utility for identifying multivessel involvement. We sought to compare feasibility and accuracy of peak treadmill exercise echocardiography vs post-exercise echocardiography for identification of multivessel coronary artery disease and to assess its incremental value when combined with clinical and exercise test variables. METHODS AND RESULTS The study group included 335 patients (228 men; mean (+/- SD) age 60 +/- 11 years). Two hundred and seventy-nine patients were included on the basis of having had an exercise echocardiography and a coronary angiography within 4 months of the exercise test. To avoid bias to coronary angiography, a subgroup of 56 consecutive non-diabetic patients referred for exercise echocardiography with pretest probability of coronary artery disease <10% and had atypical chest pain or were asymptomatic were also included and considered as having no coronary artery disease. Multivessel coronary artery disease (> or = 50% diameter stenosis in >1 vessel) was confirmed in 170 patients, whereas 165 patients were considered to have one-vessel coronary artery disease or no coronary lesions. Positive exercise echocardiography was defined as ischaemia or necrosis in at least two coronary territories. Post-exercise images were acquired within 125 s after exercise (49 +/- 15). Mean heart rate (bpm) was 139 +/- 19 at peak vs 117 +/- 22 at post-exercise imaging (P<0.001). Interpretable peak and post-exercise images were obtained for all patients. Sensitivity for predicting multivessel disease was higher with peak than with post-exercise imaging (79 vs 55%, P<0.001), with lower specificity (79 vs 88%, P<0.05). Predictive positive value was similar (80 vs 83%). Negative predictive value was again higher with peak imaging (78 vs 66%, P<0.01). Total accuracy was not different (79 vs 72%). A stepwise logistic regression analysis identified peak exercise echocardiography positivity for multivessel coronary artery disease as the strongest independent predictor of multivessel disease (odds ratio (OR): 7.36); also significant were male gender (OR: 4.22), diabetes mellitus (OR: 4.28), previous myocardial infarction (OR: 3.12) and increment of product heart rate x blood pressure (OR: 1.00). CONCLUSIONS Peak treadmill exercise echocardiography is technically feasible and has higher sensitivity and negative predictive value for predicting multivessel disease than post-treadmill exercise echocardiography. This method adds independent and incremental values to clinical and exercise variables for the diagnosis of multivessel coronary artery disease. Therefore, in the clinical setting, peak exercise echocardiography should be performed to diagnose multivessel coronary artery disease.

Abstract
UNLABELLED Lemierre syndrome is a severe postanginal sepsis complicated by internal jugular thrombophlebitis. We report on a 14 y-old girl affected by high fever, shivering chills, headache, severe lateral neck pain, left ocular proptosis and general malaise. Magnetic resonance imaging of the head and neck showed right internal jugular vein and sigmoid sinus thrombosis. Fusobacterium sp. was identified in the blood culture. CONCLUSION Our report is a reminder that Lemierre syndrome still exists and remains potentially life threatening. A high index of suspicion is necessary to prompt diagnosis and treatment.

Abstract
Many drugs and xenobiotics are lipophilic and they should be transformed into more polar water soluble compounds to be excreted. Cimetidine inhibits cytochrome P450. The aim of this study was to investigate the preventive and/or reversal action of cimetidine on cytochrome P450 induction and other metabolic alterations provoked by the carcinogen p-dimethylaminoazobenzene. A group of male CF1 mice received a standard laboratory diet and another group was placed on dietary p-dimethylaminoazobenzene (0.5% w w(-1). After 40 days of treatment, animals of both groups received p-dimethylaminoazobenzene and two weekly doses of cimetidine (120 mg kg(-1), i.p.) during a following period of 35 days. Cimetidine prevented and reversed delta-aminolevulinate synthetase induction and cytochrome P450 enhancement provoked by p-dimethylaminoazobenzene. However, cimetidine did not restore haem oxygenase activity decreased by p-dimethylaminoazobenzene. Enhancement in glutathione S-transferase activity provoked by p-dimethylaminoazobenzene, persisted in those animals then treated with cimetidine. This drug did not modify either increased lipid peroxidation or diminution of the natural antioxidant defence system (inferred by catalase activity) induced by p-dimethylaminoazobenzene. In conclusion, although cimetidine treatment partially prevented and reversed cytochrome P450 induction, and alteration on haem metabolism provoked by p-dimethylaminoazobenzene AB, it did not reverse liver damage or lipid peroxidation. These results further support our hypothesis on the necessary existence of a multiple biochemical pathway disturbance for the onset of hepatocarcinogenesis initiation.

Abstract
BACKGROUND AND AIMS Tamoxifen (TMX) has proven to be an effective palliative treatment for advanced breast cancer with low reported incidence of side effects. TMX has been demonstrated to be an initiator and/or a promoter in the rat model of hepatocarcinogenesis. To document the long-term effect of TMX in mice treated with p-dimethylaminoazobenzene (DAB), we have investigated the time response action of these drugs on different biochemical parameters. METHODS A group of animals was placed on dietary DAB (0.5%, w/w) during a period of 28 weeks. Control animals received a standard laboratory diet. Two other groups of non-treated and DAB-treated animals received TMX citrate (0.025%, w/w) in the diet since day 20. RESULTS The activities of the enzymes involved in heme synthesis and degradation as evaluated in the DAB group was not further affected by TMX. DAB and/or TMX treatment significantly increased the content of total cytochrome P450 and also the activity of glutathione S-transferase indicating liver damage. In all treated groups oxidative stress and an adaptive response of the natural defense system (catalase and superoxide dismutase) were demonstrated. Histological and morphological studies revealed liver cell hyperplasia in DAB treated group; however, only in the DAB+TMX group solid, trabecular and acinar hepatocellular carcinoma was confirmed at the end of the experimental trial. CONCLUSION We have demonstrated that TMX produced changes in hepatic enzyme activities which may be relevant for the metabolism and disposition of this and/or other drugs. Because liver tumors could be initiated and promoted by several agents which need to be activated, the possible hazard of TMX should be considered. This study reports that long-term treatment with TMX enhances hepatocarcinogenesis induced by DAB. The widespread use of TMX as an anticancer agent adds to the significance of this study.

Abstract
Painful ophthalmoplegia in childhood has different causes. One is Tolosa-Hunt syndrome, in which a first episode may be difficult to diagnose because of its clinical similarity to ophthalmoplegic migraine. A 10-year-old male with painful ophthalmoplegia and a cavernous sinus inflammation associated with an intracavernous carotid stenosis demonstrated by magnetic resonance imaging and angiography is reported. These findings resolved in follow-up imaging. This report suggests that in the presence of painful ophthalmoplegia, magnetic resonance imaging detection of cavernous sinus inflammation can facilitate the diagnosis of Tolosa-Hunt syndrome when other causes are excluded.

Abstract
Choroid plexus neoplasms (CPN) are rare tumors occurring with a relative incidence of 0.5% of intracranial neoplasms in all age groups and 1.5-6.4% of all pediatric brain tumors. In children, the most common site of origin is the atria of the lateral ventricles where the CPN may represent either a carcinoma or a benign papilloma. CPN arising in the fourth ventricle are more common in adults, and are more likely to represent a benign papilloma. We present 2 children with CPN arising from the inferior fourth ventricle with similar features on MRI, one of which represented a benign papilloma and the other a malignant carcinoma. CPN should be included, even in young children, in the differential diagnosis of any infratentorial, intraventricular tumor.

Abstract
Some late complications of diabetes are associated with alterations in the structure and function of proteins due to glycation and free radicals generation. Aspirin inhibits protein glycation by acetylation of free amino groups. In the diabetic status, it was demonstrated that several enzymes of heme pathway were diminished. The aim of this work has been to investigate the in vivo effect of short and long term treatment with acetylsalicylic acid in streptozotocin induced diabetic mice. In both treatments, the acetylsalicylic acid prevented delta-aminolevulinic dehydratase and porphobilinogen deaminase inactivation in diabetic mice and blocked the accumulation of lipoperoxidative aldehydes. Catalase activity was significantly augmented in diabetic mice and the long term treatment with aspirin partially reverted it. We propose that oxidative stress might play an important role in streptozotocin induced diabetes. Our results suggest that aspirin can prevent some of the late complications of diabetes, lowering glucose concentration and probably inhibiting glycation by acetylation of protein amino groups.
