Abstract
A monitoring of apple fruit, shoot and trunk growth was performed on 15 trees, equally split according to three treatments, which determined heavily contrasting carbon assimilate availability: unmanipulated trees (FRU), thinned trees (THI) and defruited trees (DEF). Several variables describe the vegetative growth on FRU and DEF trees (shoot length, base diameter, number of fruits on shoot, and height, diameter, pruning intensity and number of fruits of the branch carrying the shoot; trunk circumference), as well as the fruit growth on FRU and THI trees (3 fruit diameters). Additional measurements from ancillary shoots (apical diameter, number of leaves, leaf dry weight, stem dry weight, fresh mass, volume) and fruits (3 diameters, dry weight) from trees undergoing the same treatments, provide a more complete (destructive) characterization of organs growth, thanks to several measurements performed across the growing season. Organs are provided with categorical variables indicating the treatment, tree, canopy height, orientation (for both shoots and fruit), as well as branch and shoot identifiers, so that hierarchical modeling of the dataset can be performed. The dataset is completed with dates and day of the year of the measurements and the accumulated growing degree days from full bloom. Data can be used to calculate apple tree absolute and relative growth rates, maximum potential growth rates, as well as shoot growth responses to thinning and pruning. The dataset can also be used to calibrate allometric relationships, estimate structural apple tree growth parameters and their variability.

Abstract
BACKGROUND To further characterize survival benefit with first-line nivolumab plus ipilimumab with two cycles of chemotherapy versus chemotherapy alone, we report updated data from the phase III CheckMate 9LA trial with a 2-year minimum follow-up. PATIENTS AND METHODS Adult patients were treatment naïve, with stage IV/recurrent non-small-cell lung cancer, no known sensitizing EGFR/ALK alterations, and an Eastern Cooperative Oncology Group performance status ≤1. Patients were randomized 1 : 1 to nivolumab 360 mg every 3 weeks plus ipilimumab 1 mg/kg every 6 weeks with two cycles of chemotherapy, or four cycles of chemotherapy. Updated efficacy and safety outcomes are reported, along with progression-free survival (PFS) after next line of treatment (PFS2), treatment-related adverse events (TRAEs) by treatment cycle, and efficacy outcomes in patients who discontinued all treatment components in the experimental arm due to TRAEs. RESULTS With a median follow-up of 30.7 months, nivolumab plus ipilimumab with chemotherapy continued to prolong overall survival (OS) versus chemotherapy. Median OS was 15.8 versus 11.0 months [hazard ratio 0.72 (95% confidence interval 0.61-0.86)]; 2-year OS rate was 38% versus 26%. Two-year PFS rate was 20% versus 8%. ORR was 38% versus 25%, respectively; 34% versus 12% of all responses were ongoing at 2 years. Median PFS2 was 13.9 versus 8.7 months. Improved efficacy outcomes in the experimental versus control arm were observed across most subgroups, including by programmed death-ligand 1 and histology. No new safety signals were observed; onset of grade 3/4 TRAEs was mostly observed during the first two treatment cycles in the experimental arm. In patients who discontinued all components of nivolumab plus ipilimumab with chemotherapy treatment due to TRAEs (n = 61) median OS was 27.5 months; 56% of responders had an ongoing response ≥1 year after discontinuation. CONCLUSIONS With a 2-year minimum follow-up, nivolumab plus ipilimumab with two cycles of chemotherapy provided durable efficacy benefits over chemotherapy with a manageable safety profile and remains an efficacious first-line treatment of advanced non-small-cell lung cancer.

Abstract
BACKGROUND AND AIMS Carbon allocation in plants is usually represented at a topological scale, specific to each model. This makes the results obtained with different models, and the impact of their scales of representation, difficult to compare. In this study, we developed a multi-scale carbon allocation model (MuSCA) that allows the use of different, user-defined, topological scales of a plant, and assessment of the impact of each spatial scale on simulated results and computation time. METHODS Model multi-scale consistency and behaviour were tested on three realistic apple tree structures. Carbon allocation was computed at five scales, spanning from the metamer (the finest scale, used as a reference) up to first-order branches, and for different values of a sap friction coefficient. Fruit dry mass increments were compared across spatial scales and with field data. KEY RESULTS The model was able to represent effects of competition for carbon assimilates on fruit growth. Intermediate friction parameter values provided results that best fitted field data. Fruit growth simulated at the metamer scale differed of ~1 % in respect to results obtained at growth unit scale and up to 60 % in respect to first order branch and fruiting unit scales. Generally, the coarser the spatial scale the more predicted fruit growth diverged from the reference. Coherence in fruit growth across scales was also differentially impacted, depending on the tree structure considered. Decreasing the topological resolution reduced computation time by up to four orders of magnitude. CONCLUSIONS MuSCA revealed that the topological scale has a major influence on the simulation of carbon allocation. This suggests that the scale should be a factor that is carefully evaluated when using a carbon allocation model, or when comparing results produced by different models. Finally, with MuSCA, trade-off between computation time and prediction accuracy can be evaluated by changing topological scales.

Abstract
AIMS Non-communicable diseases (NCDs) have become a primary health concern for most countries around the world. The aim of this research is to analyze the relevant evidence that determines the effect of socioeconomic position (SEP) on the incidence and prevalence of NCDs. METHODS A systematic literature search was performed using PubMed, Cochrane Library, and Web of Science to identify evidence regarding the relationship between income inequalities and NCDs, between 2005 and 2015. The final selection of papers was based on applied studies focusing on Organisation for Economic Co-operation and Development (OECD) countries and articles referring to three main groups of chronic diseases: cardiovascular and heart diseases, cancer, and diabetes. RESULTS A final set of 47 selected studies were fully taken into account in this review. Despite significant heterogeneity in exposure and outcomes measures, overall the evidence suggests that having low SEP increases the risk of developing cardiovascular diseases (CVDs), lung and breast cancer, and type 2 diabetes. SEP is also associated with multiple NCD risk factors such as smoking and physical inactivity. CONCLUSION Low socioeconomic status appears to have a significant consistent impact on mortality and morbidity caused by NCDs in OECD countries. Social and economic disadvantages are associated with health inequalities in terms of access to care, increased incident risk of NCDs, and early death. These findings point to the need for public health strategies and research to address socioeconomic status disparity among individuals.

Abstract
The presence of cancer stem-like cells (CSC) within canine mammary tumors, may explain partly local recurrence and spreading, since their ability to resist conventional antitumor treatments as chemo and radiotherapy. It has been recently described that simvastatin - a drug that inhibits synthesis of cholesterol - attenuates the proliferation of canine mammary CSC derived from CF41.Mg canine mammary carcinoma cells, promoting their chemosensitizing and apoptosis. The canonical Wnt/β-catenin pathway is usually activated at CSC and up-regulates multidrug resistance protein 1 (MDR1), triggering chemoresistance. In the present study, we analyze the effect of simvastatin on β-catenin/MDR1 expression in spheres obtained from the CF41.Mg cell line as a model of CSC. Simvastatin increased phosphorylation of β-catenin without affecting its total expression. Moreover, MDR1 expression was decreased by simvastatin. These results suggest that simvastatin would facilitate the degradation of β-catenin, decreasing MDR1 expression and contributing to the chemosensitizing effects of the statin on canine mammary CSC.

Abstract
UNLABELLED Bioethanol for use in vehicles is becoming a substantial part of global energy infrastructure because it is renewable and some emissions are reduced. Carbon monoxide (CO) emissions and total hydrocarbons (THC) are reduced, but there is still controversy regarding emissions of nitrogen oxides (NOx), aldehydes, and ethanol; this may be a concern because all these compounds are precursors of ozone and secondary organic aerosol (SOA). The amount of emissions depends on the ethanol content, but it also may depend on the engine quality and ethanol origin. Thus, a photochemical chamber was used to study secondary gas and aerosol formation from two flex-fueled vehicles using different ethanol blends in gasoline. One vehicle and the fuel used were made in the United States, and the others were made in Brazil. Primary emissions of THC, CO, carbon dioxide (CO2), and nonmethane hydrocarbons (NMHC) from both vehicles decreased as the amount of ethanol in gasoline increased. NOx emissions in the U.S. and Brazilian cars decreased with ethanol content. However, emissions of THC, CO, and NOx from the Brazilian car were markedly higher than those from the U.S. car, showing high variability between vehicle technologies. In the Brazilian car, formation of secondary nitrogen dioxide (NO2) and ozone (O3) was lower for higher ethanol content in the fuel. In the U.S. car, NO2 and O3 had a small increase. Secondary particle (particulate matter [PM]) formation in the chamber decreased for both vehicles as the fraction of ethanol in fuel increased, consistent with previous studies. Secondary to primary PM ratios for pure gasoline is 11, also consistent with previous studies. In addition, the time required to form secondary PM is longer for higher ethanol blends. These results indicate that using higher ethanol blends may have a positive impact on air quality. IMPLICATIONS The use of bioethanol can significantly reduce petroleum use and greenhouse gas emissions worldwide. Given the extent of its use, it is important to understand its effect on urban pollution. There is a controversy on whether there is a reduction or increase in PM emission when using ethanol blends. Primary emissions of THC, CO, CO2, NOx, and NMHC for both cars decreased as the fraction of ethanol in gasoline increased. Using a photochemical chamber, the authors have found a decrease in the formation of secondary particles and the time required to form secondary PM is longer when using higher ethanol blends.

Abstract
This study aims to this study is to compare the co-infection Plasmodium falciparum + Plasmodium vivax and compare the detection of cases of mixed-species malaria using light microscopy versus semi-nested multiplex PCR (sPCR). Investigators collected 3060 samples at a rural health centre in Ethiopia from December 2010 to October 2011. Two capillary blood specimens were taken from each patient, one for diagnosis of Plasmodium infection by light microscopy and the other for sPCR-based diagnosis. LM detected 627 positive cases; these samples, together with 582 negatives by LM, were also subjected to sPCR testing. Of the 627 positive samples by LM, 68.4% were positive for P. vivax, 30.5% for P. falciparum, and 1.1% for P. falciparum + P. vivax co-infection. Using the sPCR technique, we identified 788 samples positive for Plasmodium: 33.0% for P. vivax, 26.5% for P. falciparum, 3.7% for P. falciparum + P. vivax co-infection, 2.0% for P. ovale and 0.8% for P. vivax + P. ovale co-infection. In the case of P. falciparum + P. vivax co-infection, light microscopy diagnosis showed a sensitivity of 11.1%, a specificity of 99.8%, a positive predictive value of 71.4% and a negative predictive value of 96.6%. The concordance rate for identifying P. falciparum + P. vivax co-infection (kappa statistic) with microscopy and sPCR was 0.184. The LM approach has low sensitivity for the detection of mixed-species infections, while sPCR is more useful.

Abstract
In some patients with suspected de novo or recurrent lymphoma, the absence of a palpable mass or peripheral lymph node enlargement can be a diagnostic challenge. We report our experience of fine needle aspiration (FNA) and biopsy in the management of 47 consecutive patients investigated in our institution over a period of 4 years. Lymphoma was suspected in 32 cases, and recurrent disease in 15 cases. Cytology was performed in all patients and biopsy in 16 patients, when a safe approach was possible. The specimens were obtained with computed tomography guidance and were diagnostic by cytology in 85% of cases: 28 patients had a newly diagnosed lymphoma and 3 had recurrent disease; residual fibrosis was diagnosed in 2 cases. Five patients with a previously diagnosed lymphoma had a new neoplasm: lung carcinoma: 3, renal adenocarcinoma: 1, metastatic lymph nodes: 1. One patient had non-neoplastic intercurrent disease (pulmonary nocardiosis). In 7 patients, no conclusive tissue was obtained (acellular: 1, blood: 3, necrosis: 3). In one case of suspected recurrent disease, a false-positive result was obtained. Cytology always allowed distinction between non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD), with attempts to subclassify NHL according to the International Working Formulation. In 12 patients, immunochemical studies could be performed for immunologic subclassification of lymphoma on the basis of cytology (n = 6) and biopsy (n = 6). Our results show that percutaneous fine needle aspiration cytology is a reliable method for the diagnosis and classification of lymphoma, and immunologic studies can be performed on cytology alone if biopsy is unsafe.

Abstract
African trypanosomiasis, leishmaniasis, and Chagas disease are 3 neglected tropical diseases for which current therapeutic interventions are inadequate or toxic. There is an urgent need to find new lead compounds against these diseases. Most drug discovery strategies rely on high-throughput screening (HTS) of synthetic chemical libraries using phenotypic and target-based approaches. Combinatorial chemistry libraries contain hundreds of thousands of compounds; however, they lack the structural diversity required to find entirely novel chemotypes. Natural products, in contrast, are a highly underexplored pool of unique chemical diversity that can serve as excellent templates for the synthesis of novel, biologically active molecules. We report here a validated HTS platform for the screening of microbial extracts against the 3 diseases. We have used this platform in a pilot project to screen a subset (5976) of microbial extracts from the MEDINA Natural Products library. Tandem liquid chromatography-mass spectrometry showed that 48 extracts contain potentially new compounds that are currently undergoing de-replication for future isolation and characterization. Known active components included actinomycin D, bafilomycin B1, chromomycin A3, echinomycin, hygrolidin, and nonactins, among others. The report here is, to our knowledge, the first HTS of microbial natural product extracts against the above-mentioned kinetoplastid parasites.

Abstract
Lactobacillus reuteri INIA P579 was used for the production and purification of reuterin. The purity of reuterin was assessed by high resolution electrospray ionization mass spectrometry (HRESIMS) and nuclear magnetic resonance (NMR) spectroscopy. After purification, reuterin concentration obtained was 1.3 M. The inhibitory activity using Escherichia coli K12 as indicator strain was estimated to be 510 AU/ml. Survival curves in tryptic soy broth revealed that reuterin required to inhibit the growth of three Listeria monocytogenes strains was in the range of 2-4 AU/ml. Purified reuterin (10 AU/g) significantly reduced the growth of L. monocytogenes in cold-smoked salmon kept under moderate or strong temperature abuse conditions. After 15 d at 8 °C, cold-smoked salmon with added reuterin exhibited L. monocytogenes counts 2.0 log CFU/g lower than control smoked salmon with no reuterin added. At 30 °C, reuterin also controlled the growth of the pathogen, with counts 1.4 and 0.9 log CFU/g lower than those observed in control smoked salmon after 24 and 48 h, respectively. The addition of purified reuterin might be used as a hurdle technology to improve the safety and extend the shelf-life of lightly preserved seafood products such as cold-smoked salmon.

Abstract
BACKGROUND Diseases of the thyroid are not uncommon, particularly in the highlands of Ethiopia. The aim of the present study was to describe the experience of thyroid surgery in a rural hospital in Southern Ethiopia. METHODS The present study was based on review of surgical cases of thyroid diseases operated in a rural hospital in Southern Ethiopia during the period 2009-2010. RESULTS During the study period, 211 patients underwent surgery for goiter. The mean age was 31.9 years (range: 14-80 years). The sex ratio, M:F, was 1:9. A total of 103 patients had unilateral nodules, and in 108 patients the nodules were located bilaterally. The mean duration of symptoms was 5.7 years (range: 0.7-25 years). In total, 161 (76.7 %) subtotal thyroidectomy operations, and 50 (23.3 %) hemi-thyroidectomy operations were performed. Histological examination revealed multinodular goiters in 203 (96.2 %) cases. Papillary and follicular cancers were found in 7 (3.3 %) and 1 (0.5 %) cases, respectively. CONCLUSIONS Thyroid surgery is feasible in a small rural Ethiopian District Hospital. The provision of surgical services in rural areas of low income and middle income countries is extremely important and delivers more health opportunities to the local people.

Abstract
Gene expression profiles have been associated with clinical outcome in patients with diffuse large B-cell lymphoma (DLBCL) treated with anthracycline-containing chemotherapy. Using Affymetrix HU133A microarrays, we analyzed the lymphoma transcriptional profile of 30 patients treated with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) and 23 patients treated with rituximab (R)-CHOP in the Groupe d'Etude des Lymphomes de l'Adulte clinical centers. We used this data set to select transcripts showing an association with progression-free survival in all patients or showing a differential effect in the two treatment groups. We performed real-time quantitative reverse transcription-PCR in the 23 R-CHOP samples of the screening set and an additional 44 R-CHOP samples set to evaluate the prognostic significance of these transcripts. In these 67 patients, the level of expression of 16 genes and the cell-of-origin classification were significantly associated with overall survival, independently of the International Prognostic Index. A multivariate model comprising four genes of the cell-of-origin signature (LMO2, MME, LPP and FOXP1) and two genes related to immune response, identified for their differential effects in R-CHOP patients (APOBEC3G and RAB33A), demonstrated a high predictive efficiency in this set of patients, suggesting that both features affect outcome in DLBCL patients receiving immunochemotherapy.

Abstract
BACKGROUND Protein kinase C beta (PKCbeta), a pivotal enzyme in B-cell signaling and survival, is overexpressed in most cases of mantle cell lymphoma (MCL). Activation of PI3K/AKT pathway is involved in pathogenesis of MCL. Enzastaurin, an oral serine/threonine kinase inhibitor, suppresses signaling through PKCbeta/PI3K/AKT pathways, induces apoptosis, reduces proliferation, and suppresses tumor-induced angiogenesis. PATIENTS AND METHODS Patients with relapsed/refractory MCL, and no more than four regimens of prior therapy, received 500 mg enzastaurin, orally, once daily. RESULTS Sixty patients, median age 66 years (range 45-85), Eastern Cooperative Oncology Group performance status of zero to two (48% had baseline International Prognostic Index of 3-5), were enrolled. Most patients had prior CHOP-like chemotherapy and/or rituximab (median = 2 regimens). No drug-related deaths occurred. There was one case each of grade 3 anemia, diarrhea, dyspnea, vomiting, hypotension, and syncope. Fatigue was the most common toxicity. Although no objective tumor responses occurred, 22 patients (37%, 95% CI 25% to 49%) were free from progression (FFP) for > or =3 cycles (one cycle = 28 days); 6 of 22 were FFP for >6 months. Two patients remain on treatment and FFP at >23 months. CONCLUSION Freedom from progression for >6 months in six patients and a favorable toxicity profile with minimal hematological toxicity indicate that enzastaurin warrants evaluation as maintenance therapy and combination chemotherapy in MCL.

Abstract
BACKGROUND High-dose therapy (HDT) with stem-cell support is the reference treatment for relapsed lymphoma, but is not appropriate for all patients. Conventional salvage chemotherapies have been used with limited efficacy and significant toxicity. Rituximab, gemcitabine and oxaliplatin are active as single agents in relapsed or refractory lymphoma, and have demonstrated synergistic effects in vitro and in vivo. PATIENTS AND METHODS Forty-six patients with relapsed or refractory B-cell lymphoma received up to eight cycles of R-GemOx (rituximab 375 mg/m(2) on day 1, gemcitabine 1000 mg/m(2) and oxaliplatin 100 mg/m(2) on day 2). The majority (72%) had diffuse large B-cell lymphoma. RESULTS After four cycles of R-GemOx, the overall response rate was 83% [50% complete response (CR)/unconfirmed CR (CRu)]. High CR/CRu rates were observed in all histological subtypes. In patients who had previously received rituximab, the CR/CRu rate after eight cycles was 65%. The 2-year event-free and overall survival rates (median follow-up of 28 months) were 43% and 66%, respectively. Among responders, the probability of being disease free for 2 years was 62%. Treatment was generally well tolerated. CONCLUSION R-GemOx shows promising activity with acceptable toxicity in patients with relapsed/refractory B-cell lymphoma who are not eligible for HDT.

Abstract
7514 Background: In diffuse large B-cell lymphoma, the combination of rituximab and CHOP (R-CHOP) has been proved to reduce bcl-2-associated treatment failure in elderly patients. However, some deaths could be due to age-associated morbidity such as cardio-vascular events. Patients and Methods: We therefore, addressed the question of its long-term impact by a competing risks analysis of 292 patients from the previously updated LNH-98–5 trial by the Groupe d’Etude des Lymphomes de l’Adulte (GELA) (Feugier et al, J Clin Oncol 2005). Using the competing risk formulation of Cox model regression, we investigated the effect of the explanatory variables on different competing events during the disease’s course such as progression, relapse, or death. Results: With a median follow-up of 5 years, R-CHOP was associated with a better survival than CHOP in 193 bcl-2-positive patients (56 ± 9% vs 42 ± 11%, P = 0.01), whereas in 99 bcl-2-negative patients there was no difference (58 ± 14% vs 52 ± 15% vs, P = 0.6). Results of competing risks analysis are given in table. Of particular interest, R-CHOP significantly decreased the risk of progression or relapse in both bcl-2-positive (RR = 2.6, P < 0.001) and bcl-2 negative (RR = 2.2, P = 0.01) and had no impact on the risk of death in complete remission patients (age over 70 remained an adverse factor). After relapse, aa-IPI 2–3 (RR = 2.9, P < 0.0001) and bcl-2 overexpression (RR = 1.5, P = 0.03) had still a significant effect on the risk of death but not front-line R-CHOP and age above 70. Conclusion: These findings highlight the role of rituximab in the sensitization to drug-induced apoptosis without inducing long-term sequel. However, Bcl2 positive patients failed to salvage treatment after relapse. [Table: see text] No significant financial relationships to disclose.

Abstract
7562 Background: High-dose therapy with autologous stem cell support (HDT) is an established treatment for chemosensitive relapse in lymphoma. However, not all patients are candidates for HDT because of age, comorbidities or previous HDT. In addition,effective and less toxic alternatives to classical Cisplatin/ARA-C-based salvage regimens are needed. Methods: Based on the clinical activity, tolerability of rituximab (R), gemcitabine (G) and oxaliplatin (Ox) and synergy between these drugs, the R-GEMOX regimen was designed with R (375mg/m2 d 1), G (1,000 mg/m2 d 2) and Ox (100 mg/m2 d 2). Treatment was given every two weeks. Between January 2002 and June 2005, 46 patients with refractory/relapsing B-cell CD20+ lymphoma not eligible for HDT were enrolled in an unicenter pilot study whose primary objective was overall response rate (ORR) after 4 cycles (induction phase). Patients were planned to receive 8 cycles if at least PR was observed after 4 cycles. Median age was 64 years (range: 43–78) and histological subtypes were: diffuse large B-cell lymphoma (n = 33), follicular (n = 8) and mantle cell (n = 5). Prior treatments included anthracyclin in 45 patients, rituximab in 26 (56%) and HDT in 14 (30%). The median number of prior treatments was 2 (range: 1 to 5) and 13 patients (28%) had received at least 3 prior regimens. Results: 315 cycles were given. The dose administered was 100% of the intended dose for the three drugs in all patients but 8, for whom the dose of oxaliplatin was reduced due to neurotoxicity (n = 7) or preexisting renal insufficiency (n = 1). Eight patients progressed during the induction phase. After 4 cycles, responses were: 10 CR, 13 CRu and 15 PR resulting in an ORR of 83%. At the end of treatment, among the 38 responder-patients, 36 patients achieved CR (78% of the entire population), one patient remained in PR and one progressed. With a median follow-up of 27 months, the 2-year progression-free and overall survivals were 53% and 66%, respectively. NCIC grade 3–4 neutropenia and thrombocytopenia were reported in 48% and 22% of the cycles. A grade 4 infection was observed in only 3% of the cycles. There was no renal toxicity. Conclusions: The R-GEMOX regimen shows promising activity with an acceptable toxicity. It is currently evaluated in a multicentric phase II study. [Table: see text]

Abstract
PURPOSE To analyze the long-term outcome of patients included in the Lymphome Non Hodgkinien study 98-5 (LNH98-5) comparing cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) to rituximab plus CHOP (R-CHOP) in elderly patients with diffuse large B-cell lymphoma. PATIENTS AND METHODS LNH98-5 was a randomized study that included 399 previously untreated patients, age 60 to 80 years, with diffuse large B-cell lymphoma. Patients received eight cycles of classical CHOP (cyclophosphamide 750 mg/m(2), doxorubicin 50 mg/m(2), vincristine 1.4 mg/m(2), and prednisone 40 mg/m(2) for 5 days) every 3 weeks. In R-CHOP, rituximab 375 mg/m(2) was administered the same day as CHOP. Survivals were analyzed using the intent-to-treat principle. RESULTS Median follow-up is 5 years at present. Event-free survival, progression-free survival, disease-free survival, and overall survival remain statistically significant in favor of the combination of R-CHOP (P = .00002, P < .00001, P < .00031, and P < .0073, respectively, in the log-rank test). Patients with low-risk or high-risk lymphoma according to the age-adjusted International Prognostic Index have longer survivals if treated with the combination. No long-term toxicity appeared to be associated with the R-CHOP combination. CONCLUSION Using the combination of R-CHOP leads to significant improvement of the outcome of elderly patients with diffuse large B-cell lymphoma, with significant survival benefit maintained during a 5-year follow-up. This combination should become the standard for treating these patients.

Abstract
BACKGROUND Data are still conflicting on the indication of front-line autologous stem-cell transplantation (ASCT) as consolidation for aggressive lymphoma. To assess the therapeutic effect of ASCT among different aggressive lymphoma subtypes, we conducted a matched-control analysis by pooling the data from two Groupe d'Etude des Lymphomes de l'Adulte (GELA) trials. PATIENTS AND METHODS Between October 1987 and September 1998, 330 patients received ASCT after achieving complete remission with the ACBVP induction regimen. The histological slides showed: B aggressive non-Hodgkin's lymphoma (B-NHL) in 249 patients (75%), T-NHL in 52 patients (15%) (including 23 T anaplastic) and non-classified NHL in 29 patients. The age-adjusted International Prognostic Index (aaIPI) was 2 or 3 in 66%. Patients were matched with controls from the same GELA database but treated with chemotherapy only. RESULTS ASCT did not benefit non-anaplastic T-NHL patients [5-year overall survival (OS) 44% (chemotherapy) versus 49% (ASCT), P=0.87; disease-free survival (DFS) 38% versus 45%, P=0.89] in comparison with B-NHL [5-year OS 77% (chemotherapy) versus 79% (ASCT), P=0.64; DFS 67% versus 72%, P=0.13]. However, for B-NHL patients with aaIPI score 2 or 3, the benefit of ASCT was significant. CONCLUSIONS This cohort study confirms the high efficacy of front-line ASCT in responding aggressive B-NHL patients with adverse prognostic factors.

Abstract
Purpose Improved survival has been observed in aggressive non-Hodgkin's lymphoma (NHL) patients with adverse prognostic factors when autotransplantation (ASCT) was performed after complete remission. However, there is no agreement on the prognostic factors for patients treated with ASCT. We aimed to estimate the prognostic effect of clinical and biologic variables on relapse and survival rates by pooling the data from two trials. Patients and Methods Of the patients treated in the LNH87 and LNH93 trials, 330 under age 60 years achieved complete remission after high-dose cyclophosphamide, doxorubicin, vincristine, and prednisone, and received consolidative ASCT; 16% of patients had T-cell NHL. The International Prognostic Index (IPI) score was 0 for 11%, 1 for 23%, 2 for 51%, and 3 for 15%. Univariate and Cox multivariate survival analyses were retrospectively performed on this population. Results Overall survival was 75 ± 5% at 5 years and disease-free survival (DFS) 67 ± 5%. For T-cell NHL, these scores were 54% and 44%, respectively. The IPI score had no prognostic value and only the following parameters adversely affected overall survival and DFS (P < .05): marrow involvement; more than one extranodal site; histology (nonanaplastic T-cell v others); and type of anthracycline (mitoxantrone v doxorubicin, for DFS only). Conclusion These results suggest that ASCT can prevent relapse in patients with adverse IPI factors. However, patients presenting with a nonanaplastic T-cell phenotype, more than one extranodal site, or marrow involvement still have a higher risk of relapse. These factors should be taken into account when designing post-ASCT maintenance studies.

Abstract
Louse-borne relapsing fever (LBRF) is endemic in Ethiopia. The epidemiological and clinical aspects of LBRF and the differences between the infection in children and that in adults were investigated in a rural hospital in Ethiopia. During the 5-year study (1997-2002), 197 patients had a confirmed diagnosis of LBRF. Most (62.1%) of the cases were children under 15 years of age. The adult cases (i.e. those aged > or =15 years) were far more likely to present with headache (76.9% v. 40%; P <0.001), musculo-skeletal pains (61.5% v. 30.5%; P <0.001), dizziness (64% v. 39%; P =0.002) and bleeding (16.9% v. 3.8%; P =0.005) than the paediatric. The overall level of case fatality was 6.4%. Death appeared to be significantly associated with adulthood (P =0.01), delay in consultation (P =0.026) and the presence of vomiting (P =0.023). LBRF is clearly still a public-health problem in Ethiopia, where the clinical manifestations of the disease differ according to the age of the case.

Abstract
BACKGROUND Rituximab induces clinical response in advanced B-cell lymphoma and is efficient in removing circulating B-cell from peripheral blood. We therefore postulated that rituximab might be a useful in vivo purging agent before high-dose therapy in this setting. PATIENTS AND METHODS Fourteen patients with relapsed follicular, marginal zone and mantle cell lymphomas (11, two and one cases, respectively) and a PCR-detectable molecular marker were treated first with rituximab, then a mobilization chemotherapeutic regimen, followed by high-dose therapy with peripheral blood stem cell transplantation. PCR analyses were performed in peripheral blood before rituximab and during follow-up, and in harvest. RESULTS Harvests were free of PCR-detectable molecular marker in nine of the 11 studied cases (82%). After high-dose therapy, clinical complete remission was obtained in 13 (93%) patients and molecular remission in 11 (79%). With a median follow-up of 3 years, the 14 transplanted patients were alive, 11 of them remaining in clinical complete remission and eight in molecular remission at last follow-up. CONCLUSION Rituximab treatment followed by high dose therapy appears to be effective in achieving complete clinical and molecular response. In vivo harvest purging is predictive of prolonged clinical and molecular remission.

Abstract
Plum pox virus (PPV) strain D was first detected in Chile in 1992 infecting Prunus trees including peaches, nectarines, apricots, and plums. Since then, quarantine efforts have included periodic surveys in the central zone of the country, the main region for stone fruit production. This work describes the characterization of six PPV isolates from this area of Chile, using biological and molecular approaches. PPV isolates were introduced into Prunus tomentosa and Nicotiana benthamiana hosts by grafting and mechanical inoculation, respectively. Symptoms were evaluated by following the appearance of circular necrotic spots and mosaic in leaves of P. tomentosa and mosaic and some leaf deformation in N. benthamiana. Molecular analysis was carried out using reverse transcription-polymerase chain reaction, allowing the cloning and sequencing of 1.34-kb fragments corresponding to the 3' region of the replicase gene, the complete coat protein (CP) gene, and the 3' nontranslated region of the PPV genome. Evolutionary distance analysis of these nucleotide sequences and their deduced coat protein amino acid sequences grouped the six Chilean isolates among strain D isolates, with closest genetic distances to those of Central Germany and Poland. Representative sources of these isolates suggest that strain D could be the only type of PPV currently present in Chile.

Abstract
AIMS Several enzymes from mycelial wastes of Penicillium chrysogenum fungal cultures from penicillin manufacture were studied as supplements for animal feeding. METHODS AND RESULTS Proteins were precipitated with tannic acid, acetone, ethanol or polyethyleneglycol 6000. The levels of the enzyme activities found in the different precipitates were similar. The activities of invertase, beta-1,3-glucanase, lipase and tannase were higher and those of amylase, cellulase, pectinase, protease and xylanase were lower. Precipitation with tannic acid was selected as an easy and simple method. CONCLUSIONS, SIGNIFICANCE AND IMPACT OF THE STUDY An enzymatic precipitate from these P. chrysogenum wastes, comparable to a commercial enzymatic additive used in animal feeding, was obtained.

Abstract
BACKGROUND p53 alterations have been associated with a poor prognosis in aggressive B-cell lymphoma. We investigated the clinical relevance of p53 status in diffuse large B-cell lymphoma (DLBCL), focusing on patients who belong to lower risk groups of the international prognostic index and were uniformly treated. We aimed to determine whether this biological marker could identify among such patients those with a pejorative outcome who could benefit from a distinct therapeutic approach. PATIENTS AND METHODS We studied 69 patients presenting with no, one (low-risk, n = 40) or two (low-intermediate risk, n = 29) risk factors treated with an anthracyclin-containing induction regimen. p53 exons 5-8 mutations were screened for using denaturing gradient gel electrophoresis and confirmed by direct sequencing. Immunohistochemical detection of p53 protein and of its downstream target p21 were also evaluated in 60 of 69 cases. RESULTS p53 mutations were detected in 16 of 69 (23%) lymphoma samples. The presence of a p53 gene mutation affected survival (P = 0.01), with a 6-year survival rate estimated to be 44% in mutated patients, compared with 79% in non-mutated ones. Using a stepwise Cox model, p53 mutation constituted the only parameter affecting survival (relative risk = 2.7, P = 0.03). A p53+/p21- immunohistochemical pattern (n = 15), suggestive of a disrupted p53 function, strongly correlated with p53 gene status and was associated with a lower 6-year survival rate when compared with a p53(-) or p53+/p21+ phenotype (47% versus 74%, P = 0.05). CONCLUSIONS p53 alterations constitute a pejorative biological indicator able to discriminate among clinically defined lower risk patients with DLBCL.

Abstract
INTRODUCTION The Cox model is widely used in medical research for comparing survival. Lymphomas might exhibit important differences in long-term cure rate despite a similar survival. METHODS Using log-rank test, we compared event-free survival (EFS), and the survival of 64 patients with mantle cell lymphoma (MCL), 525 patients with follicular lymphoma, and 1136 patients with diffuse centroblastic lymphoma (CB). RESULTS Although EFS and survival of MCL were significantly shorter than those of follicular lymphoma, checking the validity of the proportional hazards assumption shows that the distribution of rates of events and deaths over time did not differ in MCL and follicular lymphoma. In contrast, the ratios of hazards (events and deaths rates) did not remain constant over time in MCL and CB, because of a decrease in late events and deaths rates in the latter histological type. CONCLUSION Checking the validity of the Cox model hypothesis might be a useful tool for assessing long-term cure rate in seldom lymphoma subtypes. Despite a short overall survival, MCL should not be considered to be an aggressive lymphoma, in which available chemotherapy may cure a subset of patients.

Abstract
PURPOSE In the previous LNH87-2 study, consolidative high-dose therapy followed by stem cell transplantation (HDT) improved disease-free survival, as well as survival for patients (pts) presenting with two or three factors of the age-adjusted international prognostic index (Aa-IPI) in first complete remission (CR). In order to improve further the outcome of such patients, we conducted a pilot study of consolidative tandem autotranplant. PATIENTS AND METHODS Thirty-six patients (pts) under 60 years of age with two or three factors of the Aa-IPI were enrolled. Their main characteristics were: diffuse large B-cell lymphoma (83%), Aa-IPI three factors (50%), and marrow involved (36)%. The procedure consisted of 1) induction with four cycles of ACVBP (doxorubicin, cyclophosphamide, vindesine, bleomycin, prednisone) 2) in responding pts, peripheral blood stem cell (PBSC) collection after the fourth cycle of ACVBP (11 pts) or after an additional mobilization regimen (Cyclophosphamide-VP16) (17 pts) 3) a first HDT (mitoxantrone, cyclophosphamide, VP16 and carmustine) followed by PBSC infusion 4) a second HDT (busulfan, carboplatin and melphalan) followed by PBSC infusion. Among the 29 patients responding to induction, 28 received the first HDTand 24 the second. RESULTS The rates of three-year-event free survival and survival are 47% (95% confidence interval (95% CI: 31%-63%) and 50% (95% CI: 37%-69%), respectively. Eighteen patients remained free of evolutive disease and 18 patients have died, 15 from disease progression and three from treatment-related toxicity after tandem transplant (two veno-occlusive disease and one cerebral toxoplasmosis). CONCLUSION We conclude that tandem transplant did not improve the results of the LNH87-2 study in which patients received a single consolidative HDT.
