Saving time in the radiotherapy procedures for COVID-19 pneumonia treatment. A single-institution experience. Clin Transl Oncol 2021; 23:2344-2349. [PMID: 34013493 PMCID: PMC8133050 DOI: 10.1007/s12094-021-02634-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Accepted: 04/29/2021] [Indexed: 12/19/2022]
Abstract
Background The use of low dose radiotherapy (LD-RT) for the treatment of COVID-19 pneumonia is supported by biological rationale for its immunomodulatory effect. Some institutions have started to treat these patients showing encouraging results. To shorten procedure times is crucial for the comfort of symptomatic patients receiving respiratory support and to optimize institutional facilities. Patients and methods At our institution, LD-RT is offered to hospitalized patients with COVID-19 pneumonia and signs of early cytokine-released syndrome on behalf of a multicenter study. We designed a coordinated process flow starting from the patient transfer to the simulation CT-scan (first-step), to the end of the LD-RT treatment (last step). The times spent on each step of the process flow were evaluated. Results Mean age of treated patients was 83 (72–91) years-old. The timing parameters of the first 10 consecutive patients were analyzed. Except for the first (dummy run), patients were managed from the first to the last step in a median of 38 min (25–58, SD 10.67). The most time-consuming sub-process was the contouring of the treatment volumes and dosimetry. Conclusions LD-RT is not only an encouraging option for COVID-19 pneumonia patients, but a convenient and feasible procedure if performed in a coordinated way by reducing procedure times.

Rethinking prognostic factors in locally advanced or metastatic urothelial carcinoma in the immune checkpoint blockade era: a multicenter retrospective study. ESMO Open 2021; 6:100090. [PMID: 33740735 PMCID: PMC7980066 DOI: 10.1016/j.esmoop.2021.100090] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 01/29/2021] [Accepted: 02/21/2021] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Few studies have investigated the safety and efficacy of anti-PD-(L)1 antibodies in metastatic urothelial carcinoma (mUC) in daily clinical practice. Knowledge about the influence of baseline clinical and analytical factors on therapy outcomes is scarce. PATIENTS AND METHODS We conducted a multicenter retrospective study involving 119 previously treated or untreated mUC patients under anti-PD-(L)1 therapy in a real-world scenario. The objectives of this study were to confirm the safety and efficacy of anti-PD-(L)1 monotherapy and to identify pretreatment factors influencing therapy outcomes. In addition, an independent prognostic model for overall survival (OS) was developed and internally validated. RESULTS Median OS was 7.8 months [95% confidence interval (CI), 5.4-10.4], median progression-free survival (PFS) was 2.80 months (95% CI, 2.4-3.4), disease control rate (DCR) was 40% (95% CI, 31-49), and overall response rate (ORR) was 24% (95% CI, 15-31). Presence of peritoneal metastases was associated with poor OS [hazard ratio (HR) = 2.40, 95% CI, 1.08-5.33; P = 0.03]. Use of proton-pump inhibitors (PPI) was associated with poor OS (HR = 1.83, 95% CI, 1.11-3.02; P = 0.02) and PFS (HR = 1.94, 95% CI, 1.22-3.09; P = 0.005), and lower DCR (OR = 0.38, 95% CI, 0.17-0.89; P = 0.03) and ORR (OR = 0.18, 95% CI, 0.02-1.60; P = 0.002). The three risk category prognostic model developed included Eastern Cooperative Oncology Group performance status, PPI use, albumin level, presence of liver metastases, and presence of peritoneal metastases variables and was associated with higher risk of death (HR = 3.00, 95% CI, 1.97-4.56; P = 0.0001). CONCLUSIONS This study confirms anti-PD-(L)1 monotherapy as a safe and effective treatment option in daily clinical practice for mUC patients. It also describes the presence of peritoneal metastases as an independent prognostic factor for OS and underlines the association between PPI use and worse therapeutic outcomes. Finally, it proposes a new easy-to-use risk-assessment model for OS prediction.

Degradation of macroalgal detritus in shallow coastal Antarctic sediments. LIMNOLOGY AND OCEANOGRAPHY 2019; 64:1423-1441.

Abstract
Glaciers along the western Antarctic Peninsula are retreating at unprecedented rates, opening up sublittoral rocky substrate for colonization by marine organisms such as macroalgae. When macroalgae are physically detached due to storms or erosion, their fragments can accumulate in seabed hollows, where they can be grazed upon by herbivores or be degraded microbially or be sequestered. To understand the fate of the increasing amount of macroalgal detritus in Antarctic shallow subtidal sediments, a mesocosm experiment was conducted to track 13C- and 15N-labeled macroalgal detritus into the benthic bacterial, meiofaunal, and macrofaunal biomass and respiration of sediments from Potter Cove (King George Island). We compared the degradation pathways of two macroalgae species: one considered palatable for herbivores (the red algae Palmaria decipiens) and other considered nonpalatable for herbivores (the brown algae Desmarestia anceps). The carbon from Palmaria was recycled at a higher rate than that of Desmarestia, with herbivores such as amphipods playing a stronger role in the early degradation process of the Palmaria fragments and the microbial community taking over at a later stage. In contrast, Desmarestia was more buried in the subsurface sediments, stimulating subsurface bacterial degradation. Macrofauna probably relied indirectly on Desmarestia carbon, recycled by bacteria and microphytobenthos. The efficient cycling of the nutrients and carbon from the macroalgae supports a positive feedback loop among bacteria, microphytobenthos, and meiofaunal and macrofaunal grazers, resulting in longer term retention of macroalgal nutrients in the sediment, hence creating a food bank for the benthos.

Abstract
Abstract
Introduction
Benefit from adjuvant chemotherapy (CT) is doubtful in a high percentage of patients with early breast cancer. The 21-gene recurrence-score (RS) assay (Oncotype DX, Genomic Health) is one gene-expression assay that provide prognostic and predictive information in hormone-receptor (RH) positive breast cancer. The results of the TAILORx study have confirmed that the majority of patients with tumors RH + and HER2 negative can avoid CT without increasing their risk of relapse. From 2012 to 2015 we used Mammaprint (MMP), in our institution and 60% of cases could avoided CT (communicated in SABCS 2015). Since 2017 we use RS for this purpose.
Primary Objective
To analyze the impact of using RS to change the indication of adjuvant CT.
Secondary Objectives
To analyze the association between different clinical pathological factors and the RS value, and calculate the difference between the cost of all RS test and the cost in direct expense of the treatment with CT of all patients who could avoid it thanks to the RS
Material and methods
We analyzed all RS test performed in the three ICO centers during 2017. We sent 112 tumor samples; in 2 samples adequated RNA for RS was not obtained. We compared the adjuvant treatment initially planned according to institutional treatment protocol with the treatment given after RS. We compared the direct economic costs of CT with the costs of the diagnostic test, and performed a logistic regression analysis of some pathological factors and RS value.
Results
The RS could be determined in 110 of 112 cases, in which there was indication of adjuvant CT. Only 14 patients received CT (12,72%) with the RS value, so CT was avoided in 96 patients (87,28%).
The clinical-pathological characteristics of the series are summarized in the table 1. Of the risk factors analyzed, only grade 3 (p 0.001) and PR <20% (p<0.002) showed a statistically significant relationship with a higher probability of RS> 25. No association was found between age, nodal status, tumor diameter, Ki67, Infiltrating Ductal Carcinoma vs neither Infiltrating Lobular Carcinoma nor Lympho-Vascular invasion.
The cost of the genetic studies was 180000€ (1636€ each). The cost of each CT schedule (EC x 4 followed by paclitaxel x 12) was 7214€ and the total cost of 96 cases 692590€. Direct costs savings estimated from the reduction in CT treatment were 512590€
Conclusion: Our series shows that RS avoided unnecessary CT in 87% of cases and was more cost-effective than a previous series with MMP. G3 and RP <20 were the only pathological factors associated with an increased risk of RS> 25.

New insight on vertebral anomalies in cultured Senegalese sole (Solea senegalensis, Kaup) at early stages of development. JOURNAL OF FISH DISEASES 2017; 40:987-1000.

Abstract
Senegalese sole (Solea senegalensis, Kaup) is a promising flatfish species in aquaculture. However, skeletal anomalies are still a great concern in sole farming. Investigation of this issue is crucial to improving larval quality and optimizing production. The aim of this study was to thoroughly assess anomalies in the rachis of reared sole at early developmental stages. Sole (n = 507) were sampled at 31 or 32 days after hatching (dah). The specimens were stained with alcian blue and alizarin red and evaluated for the detection of vertebral deformities. Most fish presented 9:34:3 vertebrae in abdominal, caudal and caudal complex regions, respectively. Remarkably, all specimens showed at least one spinal anomaly. Alterations of neural/haemal elements, as well as deformities of hypurals, parhypural and epural, were recurrent. Vertebral body anomalies and/or vertebral column deviations were identified in 52% of the individuals. Vertebral deformations and fusions were common, especially in caudal complex. 'Minor' anomalies were predominant, and some of the detected disorders might be a result of non-/low-pathological processes. These results contribute a new insight into the main skeletal anomalies affecting cultured sole larvae. Further research is required to determine their impact on fish welfare and external appearances at commercial stages.

Abstract
Reared Senegalese sole Solea senegalensis Kaup show a high incidence of vertebral anomalies; however, little is known about its skeletal anomaly profile in the later farming phases. The purpose of this study was to provide a detailed description and quantification of the most common skeletal anomalies in reared Senegalese sole in the juvenile stage by means of computed radiography. A total of 374 Senegalese sole were classified according to the external morphology of the fish as normal or altered and then radiographed in latero-lateral and in dorso-ventral projections. Radiographic evaluation of anomalies focused especially on vertebral body anomalies (VBA) and vertebral column deviations (VCD). The 2 orthogonal projections provided a more complete visualization of the skeleton. Approximately 75% of the individuals showed at least 1 anomaly, while VBA and/or VCD were detected in 48.9% of the specimens. Regarding external morphology, 88% of the fish were categorized as normal, although about 72% of these normal fish displayed abnormalities in radiographies. The most frequent anomalies consisted of deformations of the caudal complex plates (hypurals, parhypural and epural), preurals and caudal vertebrae. Scoliosis was the most prevalent among VCD, affecting the caudal area in almost 15% of the individuals. The anomaly profile at the juvenile stages showed some differences compared to what has been reported previously in earlier stages of development. In light of these results, further investigation into the progression of skeletal anomalies over time and the causative factors at later stages is required.

Abstract
The goal of this article is to provide recommendations for the diagnosis and treatment of muscle-invasive and metastatic bladder cancer. The diagnosis of muscle-invasive bladder cancer is made by pathologic evaluation after transurethral resection. Recently, a molecular classification has been proposed. Staging of muscle-invasive bladder cancer must be done by computed tomography scans of the chest, abdomen and pelvis and classified on the basis of UICC system. Radical cystectomy and lymph node dissection are the treatment of choice. In muscle-invasive bladder cancer, neoadjuvant chemotherapy should be recommended in patients with good performance status and no renal function impairment. Although there is insufficient evidence for use of adjuvant chemotherapy, its use must be considered when neoadjuvant therapy had not been administered in high-risk patients. Multimodality bladder-preserving treatment in localized disease is an alternative in selected and compliant patients for whom cystectomy is not considered for clinical or personal reasons. In metastatic disease, the first-line treatment for patients must be based on cisplatin-containing combination. Vinflunine is the only drug approved for use in second line in Europe. Recently, immunotherapy treatment has demonstrated activity in this setting.

Metal uptake of Nerium oleander from aerial and underground organs and its use as a biomonitoring tool for airborne metallic pollution in cities.

Abstract
The analysis of the airborne particulate matter-PM-incorporated to plant leaves may be informative of the air pollution in the surroundings, allowing their use as biomonitoring tools. Regarding metals, their accumulation in leaves can be the result of both atmospheric incorporation of metallic PM on aboveground plant organs and root uptake of soluble metals. In this study, the use of Nerium oleander leaves as a biomonitoring tool for metallic airborne pollution has been assessed. The metal uptake in N. oleander was assessed as follows: (a) for radicular uptake by irrigation with airborne metals as Pb, Cd, Cr, Ni, As, Ce and Zn (alone and in mixture) and (b) for direct leave exposure to urban PM. Plants showed a high resistance against the toxicity of metals under both single and multiple metal exposures. Except for Zn, the low values of translocation and bioaccumulation factors confirmed the excluder behaviour of N. oleander with respect to the metals provided by the irrigation. For metal uptake from airborne pollution, young plants grown under controlled conditions were deployed during 42 days in locations of the city of Zaragoza (700,000 h, NE Spain), differing in their level of traffic density. Samples of PM2.5 particles and the leaves of N. oleander were simultaneously collected weekly. High correlations in Pb concentrations were found between leaves and PM2.5; in a lesser extent, correlations were also found for Fe, Zn and Ti. Scanning electron microscopy showed the capture of airborne pollution particles in the large and abundant substomatal chambers of N. oleander leaves. Altogether, results indicate that N. Oleander, as a metal resistant plant by metal exclusion, is a suitable candidate as a biomonitoring tool for airborne metal pollution in urban areas.

Abstract
Blood pressure (BP) evolves with age; until the 50's it is higher in men than in women, equaling and even then increasing in women. The prevalence of controlled BP appears to be similar between the sexes, but the prevalence of cardiovascular disease is higher in women than in men. The possibility that BP influences the cardiovascular risk differently according to sex must therefore be considered. While some studies suggest no difference exists, others have shown evidence of an increased risk in women with respect to men despite equal BP. In this way, it seems that the measurement of ambulatory BP, but not office BP, would mark the differences in the association between BP-gender and cardiovascular risk. It should therefore be investigated the possibility of a different BP goal for women and men, especially by evaluating ambulatory BP.

Abstract
BACKGROUND Congenital glycosylation disorders (CGDs) are a group of disorders caused by a defect in glycoprotein synthesis. Clinical manifestations may affect to different organs. AIMS To describe two new patients cases with a CGD in order to make paediatricians aware of this disorder. CLINICAL CASES Two new cases of different age and gender are presented, showing clinical manifestations, and radiological and laboratory findings compatible with CGD. One of the cases was followed up for several years. CONCLUSIONS Glycosylation disorders are a group of conditions to bear in mind when considering the diagnosis of a patient with neurological symptoms of unexplained origin, particularly in those cases that include a delay in psychomotor activity, low muscle tone, epilepsy, and hepatic or coagulation disorders, as well as in patients with cerebellar or olivopontocerebellar atrophy.

Abstract
In this paper, an optical design is presented for an anastigmatic telescope with back focal length corrected with exact ray tracing to eliminate spherical, coma, and astigmatism aberrations. The telescope is formed of three conical mirrors, two of them polished on the same substratum. The optical design is divided into three stages: we began the design obtaining the Gaussian parameters in a first-order solution; posteriorly, were obtained analytically the three mirrors' asphericity in a third-order design. The final design stage consists of the implementation of the Fermat's principle, the Abbe sine condition, and the Coddington equations for the exact correction for the three aforementioned aberrations.

Abstract
OBJECTIVE Self-expandable plastic stents (SEPS) are increasingly being used for treatment of postoperative esophageal leak. This complication occurs in 4-27% of patients after radical gastrectomy, and has a high mortality rate up to 60%.The aim of this study is to evaluate the efficacy of SEPS (Polyflex®) for treatment of post-operative esophago-jejuno anastomosis leak after radical gastrectomy for gastric cancer. MATERIAL AND METHODS During one year period patients who underwent a radical gastrectomy in our hospital for gastric cancer and developed a postoperative anastomotic leak were prospectively included in the study after signing a consent form, and treated with SEPS placement under endoscopic and fluoroscopic control for leak occlusion. RESULTS Four patients were included (3 men/1 woman). The mean interval between operation and SEPS placement was 16 days (range: 4-34). SEPS deployment was easily performed in all patients with complete occlusion of esophageal lumen in three patients. In the fourth patient we needed to deploy a second coaxial stent to achieve a complete occlusion of the fistula. SEPS migration did not happen in our series. One patient had already developed a mediastinitis by the time we placed the SEPS and he died 3 days later. Extraction of the SEPS was easily performed 4-8 weeks after deployment. CONCLUSION We achieved a complete healing of the anastomotic fistula after radical gastrectomy in 3 out of 4 patients, without major complications related to SEPS. Placement of SEPS is an appealing minimally invasive alternative to surgical repair for patients with postoperative anastomotic leak.

Abstract
*The effects of zinc (Zn) toxicity on photosynthesis and respiration were investigated in sugar beet (Beta vulgaris) plants grown hydroponically with 1.2, 100 and 300 microM Zn. *A photosynthesis limitation analysis was used to assess the stomatal, mesophyll, photochemical and biochemical contributions to the reduced photosynthesis observed under Zn toxicity. *The main limitation to photosynthesis was attributable to stomata, with stomatal conductances decreasing by 76% under Zn excess and stomata being unable to respond to physiological and chemical stimuli. The effects of excess Zn on photochemistry were minor. Scanning electron microscopy showed morphological changes in stomata and mesophyll tissue. Stomatal size and density were smaller, and stomatal slits were sealed in plants grown under high Zn. Moreover, the mesophyll conductance to CO(2) decreased by 48% under Zn excess, despite a marked increase in carbonic anhydrase activity. Respiration, including that through both cytochrome and alternative pathways, was doubled by high Zn. *It can be concluded that, in sugar beet plants grown in the presence of excess Zn, photosynthesis is impaired due to a depletion of CO(2) at the Rubisco carboxylation site, as a consequence of major decreases in stomatal and mesophyll conductances to CO(2).

Abstract
In the last decade, a new parasite that causes severe losses has been detected in farmed turbot Psetta maxima (L.), in north-western Spain. The parasite was classified as a myxosporean and named Enteromyxum scophthalmi. The aim of this study was to characterize the main histological changes that occur in E. scophthalmi-infected turbot. The parasite provoked catarrhal enteritis, and the intensity of the lesions was correlated with the progression of the infection and with the development of the parasite. Infected fish were classified into 3 groups, according to the lesional degree they showed (slight, moderate and severe infections). In fish with slight infections, early parasitic stages were observed populating the epithelial lining of the digestive tract, without eliciting an evident host response. As the disease progressed, catarrhal enteritis was observed, the digestive epithelium showed a typical scalloped shape and the number of both goblet and rodlet cells was increased. Fish with severe infections suffered desquamation of the epithelium, with the subsequent release of parasitic forms to the lumen. The dislodged enterocytes underwent anoikis, a mode of apoptosis triggered by the loss of anchorage, which might facilitate spreading of the parasite. Lymphohaematopoietic depletion was also observed, mainly in head kidney and spleen, which could contribute to the high virulence of this parasite.

Abstract
6015 Background: TPF combination is the new standard IC. Adding cetuximab to PF chemotherapy is superior to PF alone in metastatic disease. We incorporated cetuximab into IC with TPF and subsequent radiotherapy (RT) in unresectable SCCHN. Methods: Phase II trial conducted in 7 Spanish hospitals. Previously untreated pts aged 18–70 yrs, ECOG PS 0–1 with unresectable SCCHN were eligible. Induction comprised T 75mg/m2 day 1, P 75mg/m2 day 1, F 750mg/m2 days 1–5, and cetuximab 250mg/m2 days 1, 8, and 15 (initial dose 400mg/m2 on cycle (C) 1, day 1), repeated every 21 days x 4 C, with prophylactic antibiotics and G-CSF support. Subsequently, pts received accelerated RT with a concomitant boost (69.9Gy) and cetuximab 250mg/m2 weekly. The primary endpoint was the objective response rate (RR) to cetuximab TPF as neoadjuvant therapy. Simon's optimal two-stage design was used to calculate the sample size of 49 evaluable pts. Results: 50 pts were enrolled: median age 54 yrs (33–68); 44 male; all stage IV (T4=31, N2–3=40). Primary sites were: oropharynx, 23; hypopharynx, 16; oral cavity, 5; larynx, 4.41(82%) pts received all 4 cycles of cetuximab TPF; 47 pts received ≥2 C and were evaluable for response using RECIST. 3 pts received <2 C (2 deaths from intercurrent disease and febrile neutropenia, 1 secondary neoplasm diagnosed). The table shows RR. Serious grade 3/4 adverse events (AEs) were: neutropenia 24%; neutropenic fever 20%; infection 6%; thrombocytopenia 4%; diarrhea 12%; hepatotoxicity 4%; hypomagnesemia 2%. Grade 3 AEs were: nausea/vomiting 2%; mucositis 6%; renal failure 4%; asthenia 4%; rash 4%; hypotension 4%. There were 2 AE-related deaths (febrile neutropenia and hepatic insufficiency). Conclusions: The addition of cetuximab to TPF IC in pts with unresectable SCCHN yields a high RR, mainly CR, potentially prolonging survival. Cetuximab TPF combination should be given to pts with good PS with specialized support provided. [Table: see text] [Table: see text]

Abstract
e19089 Background: Bevacizumab, an anti-VEGF monoclonal antibody, improves response rates and prolongs survival in p with non squamous NSCLC when combined with carboplatin-paclitaxel or cisplatin-gemcitabine. This single-arm, open-labeled phase II trial aims to evaluate the efficacy and safety profile of B in combination with another widely used chemotherapy doublet for NSCLC: cisplatin and vinorelbine. Methods: Chemotherapy-naïve p diagnosed with stage IIIB or IV non squamous NSCLC received cisplatin (80 mg/m2), vinorelbine (25 mg/m2 IV days 1 and 8) and B (15 mg/kg IV) on day 1 every 3 weeks for up to 6 cycles followed by B 15 mg/kg alone every 3 weeks until disease progression. Main eligibility criteria were: PS 0–1, no brain metastases, no history of hemoptysis, stable cardiac condition and no full dose anticoagulation. Primary endpoint was progression-free survival and secondary endpoints were RR, duration of response, OS, 1-year survival and safety profile of the combination. Results: 38 p have been enrolled in the study and data of 27 p have been included in this analysis. P characteristics were: male 66.7%; median age 57 years (range 41–74); ECOG PS 0/1 (%) 33.3/66.7; adenocarcinoma/other (%) 74.1/25.9; stage IIIB/IV (%) 25.9/74.1. Median number of cycles for B/cisplatin/vinorelbine was 4.0 (range 1–6) and median number of cycles for B maintenance was 2 (range 1–4). 17 p were evaluable for response according to RECIST criteria: PR 29.4% and SD 41.2%. With a median follow-up of 3.9 months (range 0.7–11.1), median PFS was 4.6 months (95% CI: 2.6–6.6) and median OS has not been reached yet. Hematological toxicities were: 1 p gr. 3 anemia; 2 p gr. 3 and 2 p gr. 4 leucopenia; 10 p gr. 3, 1 p gr. 4 neutropenia and 3 p febrile neutropenia. Most common grade 3/4 non hematological toxicities were: vomiting (1p gr. 4), high blood pressure, asthenia and hyperglycemia. 1 p experienced gr. 4 abdominal pain, 1 p. gr. 4 constipation, 1 p. gr. 4 nausea and 1 p gr. 4 respiratory infection. No grade 3/4 hemoptysis were reported. Conclusions: This interim analysis shows that B in combination with cisplatin and vinorelbine is safe and well tolerated and has a promising activity in chemo-naïve p with non squamous NSCLC. Survival data will be updated. [Table: see text]

Abstract
7537 Background: Combination of platinum-based chemotherapy and radiotherapy is the standard treatment for p with unresectable stage III NSCLC, but considering the high rates of recurrence, it is necessary to improve these results. Erlotinib is an EGFR TKI that prolongs survival in p with recurrent and metastatic NSCLC. In this study, we aim to evaluate the role of erlotinib as maintenance therapy after a standard concurrent chemo-radiotherapy regimen in p with stage III NSCLC. Methods: P with unresectable stage IIIA/IIIB—without malignant effusions—NSCLC who had received a standard concurrent chemo-radiotherapy regimen and had no evidence of tumor progression were enrolled in this single arm, open-label phase II study and received erlotinib 150 mg/day po for 6 months. Main eligibility criteria were: PS 0–2, adequate bone marrow, hepatic and renal function and measurable disease by RECIST criteria. Primary endpoint was the percentage of p without evidence of disease progression after 6 months of erlotinib therapy and secondary endpoints were: PFS, OS, ORR and safety profile. Results: 49 p have been included in the study and data from 37 p are presented in this analysis. Baseline characteristics: median age 62 years (range 41–76); male 94.6%; caucasian 100%; smokers/never smokers (%) 97.3/2.7; ECOG PS 0/1/2 (%) 18.9/75.7/2.7; adenocarcinoma/squamous cell carcinoma/large cell carcinoma (%) 16.2/75.7/5.4; stage IIIA/IIIB (%) 16.2/83.8. Most common previous chemo-radiotherapy regimen is cisplatin/docetaxel/RT (83.8%). 27 p were evaluable for tumor response: CR 22.2%; PR 12.8%; SD 55.6%; PD 7.4%. Median TTP was 7.3 months (95% CI 5.8–16.9) and median OS was 18.7 months (95% CI 11.8-NA). Most common adverse events related to erlotinib were rash 30.6% (3 p gr. 3) and diarrhea 16.7%. Conclusions: Erlotinib as maintenance therapy is an active and well tolerated treatment after concurrent chemo- radiotherapy in p with stage III NSCLC. In spite of the majority of patients are caucasian, males, smokers with squamous cell carcinoma, maintenance with single agent erlotinib reached a promising median OS of 18.7 months. Updated data will be presented. No significant financial relationships to disclose.

Bacterial community dynamics during bioremediation of diesel oil-contaminated Antarctic soil. MICROBIAL ECOLOGY 2009; 57:598-610.

Abstract
The effect of nutrient and inocula amendment in a bioremediation field trial using a nutrient-poor Antarctic soil chronically contaminated with hydrocarbons was tested. The analysis of the effects that the treatments caused in bacterial numbers and hydrocarbon removal was combined with the elucidation of the changes occurring on the bacterial community, by 16S rDNA-based terminal restriction fragment length polymorphism (T-RFLP) typing, and the detection of some of the genes involved in the catabolism of hydrocarbons. All treatments caused a significant increase in the number of bacteria able to grow on hydrocarbons and a significant decrease in the soil hydrocarbon content, as compared to the control. However, there were no significant differences between treatments. Comparison of the soil T-RFLP profiles indicated that there were changes in the structure and composition of bacterial communities during the bioremediation trial, although the communities in treated plots were highly similar irrespective of the treatment applied, and they had a similar temporal dynamics. These results showed that nutrient addition was the main factor contributing to the outcome of the bioremediation experiment. This was supported by the lack of evidence of the establishment of inoculated consortia in soils, since their characteristic electrophoretic peaks were only detectable in soil profiles at the beginning of the experiment. Genetic potential for naphthalene degradation, evidenced by detection of nahAc gene, was observed in all soil plots including the control. In treated plots, an increase in the detection of catechol degradation genes (nahH and catA) and in a key gene of denitrification (nosZ) was observed as well. These results indicate that treatments favored the degradation of aromatic hydrocarbons and probably stimulated denitrification, at least transiently. This mesocosm study shows that recovery of chronically contaminated Antarctic soils can be successfully accelerated using biostimulation with nutrients, and that this causes a change in the indigenous bacterial communities and in the genetic potential for hydrocarbon degradation.

Abstract
PURPOSE To test efficacy and tolerability of non-platinum regimens for advanced non-small-cell lung cancer (NSCLC). METHODS Chemonaive patients with measurable stage IIIB/IV NSCLC treated with gemcitabine and cisplatin (GC), or gemcitabine and docetaxel (GD), maximumsix cycles in a phase IIB trial. RESULTS A total of 108 patients were randomized. Response rates (GC vs. GD, respectively): complete 3.6/2.0%, Partial 30.9/38.0%. Median Overall Survival (OS): 8.9 months in both groups (P = 0.53); and median time to progression (TTP): 6.2/5.5 months respectively (P = 0.61). Toxicities included (GC vs. GD, respectively): grade 3-4 neutropenia 49.1/41.2%; grade 3 thrombocytopenia 30.9/3.9%; grade 3 anemia 14.5/3.9%. Non-haematological toxicity was similar, except for nausea and vomiting, (16.3/2%); renal toxicity (3.7/0%) and hepatic toxicity (5.6/12.7%). CONCLUSIONS With a higher overall response rate and lower toxicity, GD is a good first treatment option for advanced NSCLC.

Abstract
OBJECTIVE the aim of the study was to assess the incidence, clinical presentation, location, and response to endoscopic therapy of gastrointestinal bleeding from Dieulafoy's lesion. MATERIAL AND METHOD ALL consecutive episodes of gastrointestinal bleeding due to Dieulafoy's lesion seen between 2000 and 2006 were retrospectively reviewed. All main clinical and endoscopic data were collected: type and effectiveness of endoscopic therapy, rebleeding, complications, and mortality during hospitalization. RESULTS WE found 41 patients, 26 males and 15 females, median age of 71.19 years. Dieulafoy's lesion accounted for 1.55% of all gastrointestinal bleeding episodes during the study period. The incidence of Dieulafoy's lesion was 2.2 cases/100.000 inhabitants/year. Active bleeding at endoscopy was present in 85.36%, and comorbidity in 92.68%. The stomach was the most frequent location (60.97%), followed by duodenum (29.26%). Endoscopic therapy achieved initial hemostasis in all cases. Three patients (7.31%) initially treated with epinephrine injection showed rebleeding and properly responded to a second session of endoscopic therapy. No surgery was needed. The mortality rate during hospitalization was 4.87%. CONCLUSIONS Dieulafoy's lesion is an uncommon, but potentially severe cause of gastrointestinal bleeding. It may be found in any location within the gastrointestinal tract. Endoscopic therapy is effective and safe. Injected epinephrine alone is associated with a higher risk of rebleeding.

Abstract
White lupin (Lupinus albus L.) is an annual crop that has been used for phytostabilization of acidified multi-contaminated soils. Once the culture cycle is over, after shoot harvesting, a progressive transference of contaminants from roots to soil may take place as decomposition of roots occurs. An incubation experiment with Cu, Zn, Cd, and As-loaded roots of white lupin and soils with different pH values and concentrations of these contaminants from the area affected by a mine spill at Aznalcóllar (near Seville, Spain) was performed in order to assess the effect of the decomposition of the roots to the pH and (NH4)2SO4-extractable levels of these pollutants in the soils. Pollutants loaded-roots were mineralized (56 d) at a ratio similar to animal manures (15.8-19.4% of total organic carbon) in soil. The estimated root inputs of contaminants in comparison to their extractable concentrations in soil were high, especially in the control, non-contaminated and neutral contaminated soils. However, the extractable concentrations of the toxic elements in the soil were mainly governed by soil pH. Hence, the correction and maintenance of the soil pH within the range 5-6 after lupin culture is essential for long-time phytostabilization of acidified multi-contaminated soils.

Abstract
The aim of this study was to evaluate the safety of transradial catheterization without prior withdrawal of oral anticoagulation. In total, 183 patients on long-term acenocoumarol treatment who underwent transradial catheterization were included in a prospective study. In 135 patients, the coumarin derivative was continued without interruption before and during catheterization and, in 48, the drug was stopped 48 hours in advance. No severe thromboembolic or hemorrhagic complications occurred. At 7-day follow-up, the rate of occurrence of hematomas >3 cm in size was 5.5% in the group that continued anticoagulant treatment, and 10.4% in the group that stopped oral anticoagulation (P=.31). The transradial approach appears to be a safe option for patients receiving long-term coumarin treatment and could be the technique of choice because it avoids the drawbacks and complications associated with the withdrawal of oral anticoagulation.

Abstract
OBJECTIVES The kinetics of three serological markers (IgM, IgA, and IgG) in serum, saliva, and urine samples from adult patients with primary or secondary dengue infection were studied. DESIGN Serum, saliva, and urine samples were collected from 22 patients with clinical and confirmed dengue 3 virus infection during the outbreak in Havana City in 2001. They were tested by capture IgM (MAC-ELISA), IgA (AAC-ELISA), and IgE (EAC-ELISA) and IgG ELISA inhibition method (EIM) to detect specific dengue antibodies. RESULTS Similar kinetics were observed in IgM, IgA, and IgG antibodies in saliva and IgA and IgG in urine samples from secondary cases compared with kinetics in serum samples, although the values were lower. No IgG antibody was detected in saliva and urine samples in primary cases and IgM antibody was not detected in urine samples from either primary or secondary infection. All secondary cases were positive for IgG in saliva and urine samples at day 7. The kinetics of specific IgE antibodies in primary and secondary cases were different. CONCLUSIONS The kinetics of three serological markers (IgM, IgA, and IgG) in serum, saliva, and urine samples from adult patients with primary or secondary dengue 3 virus infection were studied for the first time, showing its behavior and usefulness in dengue virus diagnosis. The specific IgE could play a role as a serological marker in secondary infections.

Risk factors associated with Enteromyxum scophthalmi (Myxozoa) infection in cultured turbot, Scophthalmus maximus (L.). Parasitology 2006; 133:433-42. [PMID: 16780606 DOI: 10.1017/s0031182006000515] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2006] [Revised: 04/11/2006] [Accepted: 04/13/2006] [Indexed: 11/07/2022]
Abstract
An epidemiological cohort study of Enteromyxum scophthalmi in cultured turbot was performed on a farm in North Western Spain. Four different ongrowing stocks (A, B, C, D) were monitored monthly until market size. Fish from stocks C and D were divided into 2 subgroups, receiving filtered (CF and DF) or unfiltered (CUF and DUF) water. The lack of water filtration was positively associated with infection prevalence, as all fish kept in filtered water remained uninfected. Parasite abundance varied seasonally (P<0.05) in stock B and subgroup CUF. Infection was also associated (P<0.05) with host weight, and the highest prevalences and intensities were detected in 101-200 g and 201-300 g fish. Distribution pattern of E. scophthalmi in subgroups CUF and DUF had a variance higher than the mean, indicating overdispersion. The minimum period necessary for the first detection of the parasite and for the appearance of disease symptoms and mortality, varied depending on the stock and introduction date, although a long pre-patent period was always observed. Several factors, such as host density, parasite recruitment and parasite-induced fish mortality can contribute to the observed distribution pattern. Risk factors found to be associated with E. scophthalmi infection, including water quality and accumulation of infective stages in the culture tanks, should be considered when designing control strategies to prevent the introduction and spread of infective stages in the facilities.

Abstract
The serotine bat (Eptesicus serotinus) accounts for 95 % of cases of human exposition to EBLV1. The aim of this study was to focus on the epidemiology and pathogenesis of EBLV1 infection in the serotine bat. Our first objective was the development of an RT-PCR technique for the specific detection of EBLV1 RNA in oro-pharyngeal swabs. This technique showed better performance than the classical immunofluorescence (IF) on brain in detecting EBLV1 in healthy flying bats. We have used this technique together with antibody detection by the fluorescent focus inhibition test (FFIT) to investigate EBLV1 circulation in 19 natural colonies of serotine bats in Andalusia (Spain) from 1998 to 2003. The survey was based on 1223 different captures of 1080 individuals that were ring banded, sampled and released. Individuals that were repeatedly captured were always found in the same colony even though some colonies were less than five Km apart. Viral circulation was detected in nine colonies either by RT-PCR, serology or both. Each colony showed a different temporal pattern of viral circulation suggesting independent endemic circulation. Some positive individuals were captured healthy in following campaigns evidencing survival after viral infection.

Abstract
BACKGROUND IgA nephropathy (IgA) is one of the most common glomerulonephritis. Renal transplantation is the treatment of choice for patients with ESRD due to any kind of glomerulopathy, including IgA and Henoch-Schönlein purpura nephritis (H-SP), but original disease recurrence is now the third most frequent cause of allograft loss. METHODS Eighty-seven cases of glomerulonephritis as the original disease were divided in two groups: group A--37 affected with 31 IgA and 6 H-SP; and group B--50 with other glomerulopathies. We compared patient and graft survivals at 5 years. To assess the presence of IgA or H-SP recurrence in group A patients, we performed an allograft biopsy in the presence of microhematuria, proteinuria, or an increased plasma creatinine. Known risk factors influencing recurrence rate were also analyzed. RESULTS Five-year patient (97% vs 95%) and graft survivals (81% vs 78%) were not significantly different between groups A and B. Patients with crescentic glomerulonephritis (CGN) at the moment of diagnosis of IgA or H-SP showed a 5-year graft survival of 71% in contrast with 100% graft survival among those with mesangial or focal and segmental glomerulosclerosis pattern (P = .03). Histological recurrence was diagnosed in eight patients: six IgA and two H-SP. Women (P = .013) and a good HLA match (P = .029) were significantly associated with the risk of recurrence. CONCLUSIONS When compared with other glomerulonephritis patients, with IgA or S-HP showed similar 5-year graft and patient survivals. Nevertheless, graft survival was shorter among patients with crescentic glomerulonephritis at the moment of diagnosis. Thus, the disease prognosis after grafting may be linked to the initial histological aggressiveness. Women and those patients transplanted with a good HLA match were prone to develop disease recurrence with a tendency toward a lower 5-year graft survival.
