Abstract
BACKGROUND The incidence of non-AIDS defining cancer (NADC) is higher in people living with HIV (PLWH) than in the general population, and it is already one of the leading causes of death in the HIV-infected population. It is estimated that the situation will be aggravated by the progressive aging of PLWH. Early diagnosis through intensive cancer screening may improve the ability for therapeutic interventions and could be critical in reducing mortality, but it might also increase expenditure and harms associated with adverse events. The aim of this study is to evaluate an enhanced screening program for early diagnosis of cancer in PLWH compared to standard practice. The specific objectives are (1) to compare the frequency of cancer diagnosed at an early stage, (2) to analyze safety of the enhanced program: adverse events and unnecessary interventions, (3) to analyze the cost-utility of the program, and (4) to estimate the overall and site-specific incidence of NADC in PLWH. METHODS We will conduct a multicenter, non-blinded, randomized, controlled trial, comparing two parallel arms: conventional vs enhanced screening. Data will be recorded in an electronic data collection notebook. Conventional intervention group will follow the standard of care screening in the participating centers, according to the European AIDS Clinical Society recommendations, and the enhanced intervention group will follow an expanded screening aimed to early detection of lung, liver, anal, cervical, breast, prostate, colorectal, and skin cancer. The trial will be conducted within the framework of the Spanish AIDS Research Network Cohort (CoRIS). DISCUSSION The trial will evaluate the efficacy, safety, and efficiency of an enhanced screening program for the early diagnosis of cancer in HIV patients compared to standard of care practice. The information provided will be relevant since there are currently no studies on expanded cancer screening strategies in patients with HIV, and available data estimating cost effectiveness or cost-utility of such as programs are scarce. An enhanced program for NADC screening in patients with HIV could lead to early diagnosis and improve the prognosis of these patients, with an acceptable rate of unnecessary interventions, but it is critical to demonstrate that the benefits clearly outweigh the harms, before the strategy could be implemented.

Abstract
Abstract
Introduction and Objectives: Cancer patients are more susceptible to infections because of the active treatment that they need to treat their disease. A new coronavirus, called SARS-CoV-2, has caused a global pandemic where cancer patients have an increased risk of morbidity and mortality associated with COVID-19. However, the incidence data of COVID-19 in cancer patient with active treatment are not known, although the main oncology societies recommend a delay and/or stop in active cancer treatment during this pandemic. Whether this stop will have an impact on the future evolution of their disease is also not known. Therefore, a study of the incidence of COVID-19 in this type of patient can help us to organize the protocols and the treatment in these high-risk patient group.
Materials and Methods: We conducted a prospective clinical study of cancer patients within active treatment (chemotherapy, palliative hormonotherapy, radiotherapy, target therapies, or immunotherapy), analyzing the number of COVID-19 diagnoses between February 26 and May 13 in two oncology services of the Andalusian community. A descriptive analysis of 692 patients with active treatment was carried out. In addition, the cumulative incidence and the differences between groups were calculated using the SPSS vs 18.
Results: A total of 692 cancer patients undergoing active treatment at the Hospital Costa del Sol (Marbella) and at the Hospital San Cecilio (Granada) were analyzed. Sixty four percent were men with a mean age of 60 years. Forty one percent had a breast cancer diagnosis, 12.9% had lung cancer, and 14.5% had colorectal tumor. Fifty three percent of them received treatment for stage IV disease, and up to 43% were delayed treatment due to pandemic. The total number of infections was 9, a cumulative incidence of 1.3%, 95% CI (0.384-2.217), and 22% of them died after developing the infection. Advanced age (p = 0.011), an admission in the 3 months prior to the diagnosis of COVID-19 (p = 0.031), and active treatment with chemotherapy (p = 0.003) were the factors that were associated with an increased risk of developing COVID-19.
Conclusions: The incidence of SARS-CoV-2 in cancer patients on active treatment is low but the mortality is high, as previously reported for these patients. Given that the incidence of COVID-19 in patients with treatment is low, we cannot conclude any role of treatment delay in the development of COVID-19 in these patients.

Abstract
PURPOSE Among the prognostic factors relevant to the condition of oncological patients, nutritional status (NS) has the greatest single impact on quality of life (QL). The goals of our study were to evaluate the influence of NS, weight loss (WL), and the presence of cachexia, prior to the initiation of chemotherapy, on the patient's QL. METHODS Adult patients (aged ≥ 18 years) diagnosed with solid tumours for whom chemotherapy was started between April 2016 and June 2017 were eligible for inclusion in the study. They were asked to complete a QL questionnaire (Functional Assessment of Cancer Treatment (FACT-G)) at the beginning. The presence or absence of cachexia was evaluated at the outset, following the definition proposed by Fearon and nutritional assessment by the Patient-Generated Subjective Global Assessment (PG-SGA) scale. RESULTS A total of 177 patients completed the FACT-G, the 60% receiving curative therapy. At the start of the treatment, 58.2% of patients had experienced WL, with an average of 4.4 ± 7.4%, and 19% were at risk of malnutrition. Patient who presented cachexia at diagnosis, were treated with palliative intention, had a Nutriscore ≥ 5 points or presented malnutrition in accordance with PG-SGA had a poorer QL (p < 0.05). Greater WL was associated with a worsened QL (p = 0.001). Breast cancer patients presented an inverse correlation between the %WL and the initial score in the FACT-G (r = - 0.304, p = 0.023), whereas no such correlation was observed for the other types of tumour (r = - 0.012, p = 0.892). CONCLUSIONS These results underline the relation of NS before starting chemotherapy and QL. Greater WL was associated with a worsened QL, especially in women with breast cancer.

Abstract
Positron annihilation lifetime spectroscopy is used to experimentally demonstrate the direct relationship between vacancies and the shift of the martensitic transformation temperature in a Ni_{55}Fe_{17}Ga_{28} alloy. The evolution of vacancies assisting the ordering enables shifts of the martensitic transformation up to 50 K. Our results confirm the role that both vacancy concentration and different vacancy dynamics play in samples quenched from the L2_{1} and B2 phases, which dictate the martensitic transformation temperature and its subsequent evolution. Finally, by electron-positron density functional calculations V_{Ni} is identified as the most probable vacancy present in Ni_{55}Fe_{17}Ga_{28}. This work evidences the capability of vacancies for the fine-tuning of the martensitic transformation temperature, paving the way for defect engineering of multifunctional properties.

Abstract
This paper shows that, for a large range of parameters, the journal editor prefers to delegate the choice to review the manuscript to the biased referee. If the peer review process is informative and the review reports are costly for the reviewers, even biased referees with extreme scientific preferences may choose to become informed about the manuscript's quality. On the contrary, if the review process is potentially informative but the reviewer reports are not costly for the referees, the biased reviewer has no incentive to become informed about the manuscript. Furthermore, if the reports are costly for referees but the peer review processes are not potentially informative, the biased reviewers will never become informed. In this paper, we also present a web resource that helps editors to experiment with the review process as a device for information transmission.

Abstract
BACKGROUND Available evidence assessing the impact of small intestinal bacterial overgrowth (SIBO) following gastrectomy is limited. OBJECTIVES To evaluate the prevalence of SIBO after gastrectomy and its association with malnutrition. To describe the antibiotic treatment required to correct it and if nutritional status improves. MATERIAL AND METHODS A prospective cohort study was performed at the Agencia Sanitaria Costa del Sol (Costa del Sol Health Agency) from 2012 to 2015. A hydrogen-methane breath test with oral glucose overload was performed. Demographic variables and nutritional parameters were collected at baseline and one month after effective treatment of SIBO. The antibiotic regimens and the number of treatment lines used were assessed. RESULTS Sixty gastrectomy patients were analysed, 58.3% of which were male. A sub-analysis of the curve was performed at 45min to minimise possible false positives, and SIBO was identified in 61.6% of cases. SIBO patients tended to have a lower BMI, although this trend was not statistically significant. After treatment with rifaximin, 94.6% of patients were still positive for SIBO, which fell to 85.7% after metronidazole. The rate of total antibiotic treatment failure was 67.6%. No statistically significant changes were found in nutritional parameters after treatment. CONCLUSIONS SIBO was identified in 61.6% of patients after gastrectomy. No correlation was found with any malnutrition parameter. Rifaximin and metronidazole were found to be largely ineffective in eradicating SIBO. When treatment was effective, the impact on malnutrition was negligible and may have been associated with other factors.

Abstract
La hemoglobinuria bacilar (HB) es una enfermedad infectocontagiosa, aguda, producida Clostridium haemolyticum, que afecta principalmente a bovinos y es predispuesta por diferentes factores. En este artículo se realiza un estudio retrospectivo de los casos de HB diagnosticados en bovinos de la provincia de Buenos Aires, por el Servicio de Diagnóstico Veterinario Especializado de INTA Balcarce durante el período 1969-2015 y los casos reportados por veterinarios privados en el Programa de Interacción Profesional en el área de influencia del Centro Regional Buenos Aires Sur del INTA durante el periodo 2001-2007. Se observó marcada estacionalidad de la enfermedad durante los meses de invierno y una asociación con un avanzado estado de preñez de los animales (88% de los casos). Solo en un 15,9 % de los casos se pudo confirmar una infestación simultánea con Fasciola hepatica en los rodeos donde se diagnosticó la enfermedad. En un 47,9 % de estos episodios los animales habían recibido previamente dos dosis de vacuna contra HB. HB es endémica e insidiosa en ciertas regiones de nuestro país. La información sobre algunos aspectos de su etiopatogenia y el control es escasa, dificultando su prevención. Estas áreas deberían ser exploradas en el futuro para tratar de mejorarlas.

Abstract
OBJECTIVES Contemporary data from country-wide cohorts are needed to reveal trends in the occurrence of acute myocardial infarction (AMI) in people living with HIV (PLWH). We analysed time trends in the standardized incidence rate (sIR) of AMI in PLWH in Spain from 2004 to 2015, and compared them with trends in the general population. METHODS A longitudinal study in a nationwide contemporary multicentre HIV-infected cohort was carried out. Data on all incident AMI events were collected, and age- and sex-standardized IRs calculated. To analyse the IR of AMI in the general population, the national rates of hospital discharges for AMI per 100 000 inhabitants stratified for age and sex from 2004 to 2015 were obtained using the morbidity report data from the National Statistics Institute. A Poisson regression model was fitted to assess the effect of covariates of interest on AMI occurrence. RESULTS The sIRs of AMI in 2004-2015 were 237.92 [95% confidence interval (CI) 225.95-249.90] and 66.75 (95% CI: 23.49-110.01) per 100 000 patient-years in male and female PLWH, respectively. There was a decrease in the sIR of AMI in male PLWH from 279.02 (95% CI: 265.46-292.59) per 100 000 person-years in 2004-2009 to 222.13 (95% CI: 210.83-233.42) per 100 000 person-years in 2010-2015. Compared with the general population, the sIR ratio was 1.41 (95% CI: 1.26-1.55) in 2004-2009, and 1.28 (95% CI: 1.15-1.43) in 2010-2014. AMI occurrence was associated with older age (P < 0.066 for each 10-year age stratum ≥ 35-years compared with the 25-34 year stratum), higher plasma HIV RNA (P < 0.001), lower CD4 count (P < 0.04 for CD4 strata > 350 cells/μL compared with the 0-100 cells/μL stratum), and the period 2004-2009 (P < 0.001). CONCLUSIONS There has been a decreasing incidence of AMI in PLWH in Spain, associated with improving immune and virological status, but the incidence of AMI has remained higher than in the general population.

BACKGROUND Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor, with the Milan criteria considered to be the gold standard for patient selection for liver transplantation (LT). MATERIALS AND METHODS We performed a descriptive observational study, reviewing 20 years of experience of LT in patients with HCC in the Fundacion Valle del Lilí in Cali, Colombia. Subgroup analysis was undertaken for periods 1999 to 2007 and 2008 to 2015. RESULTS Fifty-seven cases with a pretransplant HCC diagnosis were reviewed. In the first period patients within the Milan criteria had a recurrence-free survival at 5 years of 66.6%, and in those who exceeded the Milan criteria, recurrence-free survival was 75%. In the second period, patients within the Milan criteria, recurrence-free survival at 5 years was 93.5%, and in those who exceeded the Milan criteria, recurrence-free survival was 75.7%. No statistically significant difference was found in either period. For patients with mild and moderate tumor differentiation, the relapse survival rate at 5 years was 69.4% (95% confidence interval [CI] 35.8-87.8) and 74.7% (95% CI 44.5-90), respectively. All patients with poor tumor differentiation relapsed and died within 3 years. CONCLUSION Global and recurrence-free survival among patients who met and patients who exceeded the Milan criteria was not significantly different, suggesting an expansion of the Milan criteria to include potential recipients who were previously excluded. Obtaining histologic differentiation and identifying vascular invasion will provide a more worthwhile contribution to LT decision making.

Abstract
OBJECTIVE Pilot project focusing on the implementation and evaluation of a health education (HE) program for inmates of the prison of Ocaña I (Spain). The objective was to analyze the intentions for change in health habits and perceptions, and to assess whether the HE-program had differential effects depending on whether the participants belonged to the PAIEM or not and their socio-demographic characteristics. METHODOLOGY The participants were 65 men, who answered an ad hoc questionnaire at the end of each session. Data analysis applied was univariate and bivariate (one-way ANOVA, t-test for Equality of Means and Chi-Square test). RESULTS The average rating of the sessions was 3.51 out of 4 (SD = 0.62). The percentage of positive answers about the intention to adopt healthy habits was higher among non-PAIEM subjects (84.8%) than among those who were part of this program (57.9%). All subjects having a couple indicated an intention to change negative habits, compared to 67.3% for those without a couple. The percentage of subjects who said that their perception on the issue had changed was highest among those without education (89.7%) than among those with education (61.5%). CONCLUSIONS The evaluation of implanted HE-program implemented in the Ocaña I prison was very positive, there are differences between subjects belonging to the PAIEM and those who do not.

Abstract
The heating properties of Fe71.7Si11B13.4Nb3Ni0.9 amorphous glass-coated microwires are explored for prospective applications in magnetic hyperthermia. We show that a single 5 mm long wire is able to produce a sufficient amount of heat, with the specific loss power (SLP) reaching a value as high as 521 W/g for an AC field of 700 Oe and a frequency of 310 kHz. The large SLP is attributed to the rectangular hysteresis loop resulting from a peculiar domain structure of the microwire. For an array of parallel microwires, we have observed an SLP improvement by one order of magnitude; 950 W/g for an AC field of 700 Oe. The magnetostatic interaction strength essential in the array of wires can be manipulated by varying the distance between the wires, showing a decreasing trend in SLP with increasing wire separation. The largest SLP is obtained when the wires are aligned along the direction of the AC field. The origin of the large SLP and relevant heating mechanisms are discussed.

Abstract
Over the past two decades, magnetic hyperthermia and photothermal therapy are becoming very promising supplementary techniques to well-established cancer treatments such as radiotherapy and chemotherapy. These techniques have dramatically improved their ability to perform controlled treatments, relying on the procedure of delivering nanoscale objects into targeted tumor tissues, which can release therapeutic killing doses of heat either upon AC magnetic field exposure or laser irradiation. Although an intense research effort has been made in recent years to study, separately, magnetic hyperthermia using iron oxide nanoparticles and photothermal therapy based on gold or silver plasmonic nanostructures, the full potential of combining both techniques has not yet been systematically explored. Here we present a proof-of-principle experiment showing that designing multifunctional silver/magnetite (Ag/Fe3O4) nanoflowers acting as dual hyperthermia agents is an efficient route for enhancing their heating ability or specific absorption rate (SAR). Interestingly, the SAR of the nanoflowers is increased by at least 1 order of magnitude under the application of both an external magnetic field of 200 Oe and simultaneous laser irradiation. Furthermore, our results show that the synergistic exploitation of the magnetic and photothermal properties of the nanoflowers reduces the magnetic field and laser intensities that would be required in the case that both external stimuli were applied separately. This constitutes a key step toward optimizing the hyperthermia therapy through a combined multifunctional magnetic and photothermal treatment and improving our understanding of the therapeutic process to specific applications that will entail coordinated efforts in physics, engineering, biology, and medicine.

Abstract
PURPOSE To analyse the prognostic role of the immunohistochemical expression of pKDR in patients with advanced colorectal cancer treated with oxaliplatin and fluoropyrimidines combination chemotherapy with or without bevacizumab. METHODS Retrospective multicentre study, carried out at four hospitals in the Valencian Community (Spain). Patients evolution was compared based on the immunohistochemical expression of pKDR, classified using 4 categories: 0 (undetectable), 1 (mild), 2 (moderate) and 3 (high intensity). Patients were divided into two groups for the analysis: group 1 with low expression (0-1) vs. group 2 with high expression (2-3). RESULTS Histological samples for the pKDR analysis were available for 84 of the 112 patients selected. Seven (8.3 %) had undetectable or mild expression of pKDR (Group 1) and 77 (91.7 %) showed moderate or high expression of pKDR (Group 2). Response rate in Group 1 was 100 % compared to 54.2 % in Group 2 (p = 0.019). Progression-free survival (PFS) (15 vs. 12 months, p = 0.4) and overall survival (OS) (28 vs. 22 months, p = 0.09) were numerically but not significantly higher in patients from Group 1 vs. Group 2. Patients from Group 2 who received bevacizumab presented a significantly higher PFS (13 vs. 11, p = 0.015) and a numerically higher OS (23 vs. 17 months, p = 0.27) than those treated exclusively with chemotherapy. CONCLUSIONS Our results suggest that the absence or low expression of pKDR is associated with a better prognostic profile in patients with advanced colorectal cancer treated with chemotherapy and bevacizumab. Patients with a high pKDR expression benefit from the combination of chemotherapy with bevacizumab.

Abstract
Exposure to the tellurium oxyanion tellurite (TeO3(2-)) results in the establishment of an oxidative stress status in most microorganisms. Usually, bacteria growing in the presence of the toxicant turn black because of the reduction of tellurite (Te(4+)) to the less-toxic elemental tellurium (Te(0)). In vitro, at least part of tellurite reduction occurs enzymatically in a nicotinamide dinucleotide-dependent reaction. In this work, we show that TeO3(2-) reduction by crude extracts of Escherichia coli overexpressing the zwf gene (encoding glucose-6-phosphate dehydrogenase) takes place preferentially in the presence of NADPH instead of NADH. The enzyme responsible for toxicant reduction was identified as 6-phosphogluconate dehydrogenase (Gnd). The gnd gene showed a subtle induction at short times after toxicant exposure while strains lacking gnd were more susceptible to the toxicant. These results suggest that both NADPH-generating enzymes from the pentose phosphate shunt may be involved in tellurite detoxification and resistance in E. coli.

Abstract
BACKGROUND Endemic goiter remains a serious public health problem and 75 % of people affected live in underdeveloped countries where treatment is difficult for various reasons. The aim of this article is to report our experience in African countries with the management and surgical treatment of endemic goiter, performed in a nonhospital setting and without general anesthesia in the context of a collaborative development project by experienced endocrine surgeons. METHODS Fifty-six black African patients with a goiter were studied. Those in poor general health, the elderly, patients with either small goiters or clinical hyperthyroidism, and those presenting with an acute episode of malaria were excluded from the study. Cervical epidural anesthesia with spontaneous ventilation was used and a partial thyroidectomy was performed. The technique used, its immediate complications, and early and late follow-up were analyzed. RESULTS Surgery was performed on 31 patients with grades 3 and 4 goiter without mortality and a morbidity rate of 11.9 %, with 97 % of all complications being minor. There were no instances of dysphonia or symptomatic hypocalcemia and the mean stay was 1.57 days (range 1.25-1.93). Follow-up in the first year was 71 % and no case of severe or recurrent hypothyroidism was detected. CONCLUSIONS Surgery without general anesthesia performed in a nonhospital setting in underdeveloped countries in patients with goiter is a viable option with good results and low morbidity.

Abstract
The CERN Axion Solar Telescope has finished its search for solar axions with (3)He buffer gas, covering the search range 0.64 eV ≲ ma ≲ 1.17 eV. This closes the gap to the cosmological hot dark matter limit and actually overlaps with it. From the absence of excess x rays when the magnet was pointing to the Sun we set a typical upper limit on the axion-photon coupling of gaγ ≲ 3.3 × 10(-10) GeV(-1) at 95% C.L., with the exact value depending on the pressure setting. Future direct solar axion searches will focus on increasing the sensitivity to smaller values of gaγ, for example by the currently discussed next generation helioscope International AXion Observatory.

Abstract
A novel method for superparamagnetic nanoparticle detection using copper impedance as the sensing property is presented. The increase of impedance produced by the proximity of the nanoparticles in the copper is comparable to that of classical magnetoimpeditive materials. A physical interpretation of the detection in terms of the induction of eddy currents in the copper element by the oscillating magnetic moments of the particles is proposed. Experimental research has been done to support this hypothesis, namely, analyses of the influence of the driving current frequency and amplitude, and of the geometry and size of the sensing conductor. The ability of copper to quantify the number of nanoparticles was successfully verified, evidencing the great potential of this new method.

Abstract
The CERN Axion Solar Telescope (CAST) has extended its search for solar axions by using (3)He as a buffer gas. At T=1.8 K this allows for larger pressure settings and hence sensitivity to higher axion masses than our previous measurements with (4)He. With about 1 h of data taking at each of 252 different pressure settings we have scanned the axion mass range 0.39 eV≲m(a)≲0.64 eV. From the absence of excess x rays when the magnet was pointing to the Sun we set a typical upper limit on the axion-photon coupling of g(aγ)≲2.3×10(-10) GeV(-1) at 95% C.L., the exact value depending on the pressure setting. Kim-Shifman-Vainshtein-Zakharov axions are excluded at the upper end of our mass range, the first time ever for any solar axion search. In the future we will extend our search to m(a)≲1.15 eV, comfortably overlapping with cosmological hot dark matter bounds.

Abstract
BACKGROUND Despite years of experience with lung transplantation, perioperative morbidity rates remain high. The objective of this study was to analyze our series of lung transplant recipients, seeking to identify possible intra- and postoperative risk factors associated with mortality. PATIENTS AND METHODS We performed a descriptive, retrospective study of 224 consecutive patients undergoing lung transplantation over a period of 112 months; we excluded retransplant procedures. We gathered details of the surgical procedure and postoperative period in the recovery unit. Univariate analysis using the chi-square test identified variables associated with the incidence of mortality. RESULTS From 1999 to 2008, we performed 224 lung transplants, including 66% in men and 34% in women. Their overall mean age was 49.9 +/- 13.5 years. The conditions that led to transplantation were pulmonary fibrosis (38.4%); chronic obstructive pulmonary disease emphysema (29%); cystic fibrosis (10.7%); bronchiectasis (8.9%); pulmonary hypertension (3.1%); and other diseases (9.9%). A total of 124 (55.4%) patients underwent single and 100 (44.6%) received sequential bilateral lung transplantations. Surgical risk factors were identified in 51.3% of the cases, the most frequent being hemorrhage (25.3%), followed by severe pulmonary hypertension (14.7%) and cardiopulmonary bypass (12.1%). Greater perioperative mortality was detected among patients with surgical risk factors, namely, significantly related to cardiopulmonary bypass, pulmonary hypertension, and air leak. A higher frequency of surgical risk factors was observed among patients with bilateral lung transplantations and longer procedures, but they were not associated with greater perioperative mortality. Reoperation was necessary in 16 patients (7.2%), mainly owing to bleeding, it was not significantly related to mortality risk. CONCLUSIONS The incidence of surgical risk factors in lung transplantation was high, especially in bilateral lung transplantations and prolonged procedures. Postoperative bleeding requiring reoperation was not frequent and not associated with increased preoperative mortality in our series.

Abstract
INTRODUCTION The indication for single or double lung transplantation in patients diagnosed with pulmonary emphysema is a topic of current debate. Our aim was to analyze the differences in the incidence of perioperative complications, survival, and quality of life between single and double lung transplantations. MATERIALS AND METHODS From 1999 to 2008, 223 subjects underwent transplantation in our department, of whom 62 (28%) had a previous diagnosis of pulmonary emphysema. A retrospective study was performed to establish possible differences between group 1 (single lung) and group 2 (double lung) transplants analyzing overall survival using the Kaplan-Meier method and differences between groups using the log-rank test. Pearson chi-square test was used to compare the frequency of postoperative complications, bronchiolitis obliterans BOS acute rejection episodes, and infections. RESULTS We included 62 patients who underwent transplantation for emphysema. Cumulative 5-year survival rate, excluding preoperative mortality, was 54% overall, 59% for group 1, and 56% for group 2. No significant differences were observed between the groups (P = .47). The frequency of BOS was 34% in group 1 and 42% in group 2 (P = .52). At least 1 acute rejection episode occurred in 52% of group 1 patients and 51% of group 2 patients (P = .98). Bacterial infections were experienced by 50% of group 1 patients and 54% of group 2 patients (P = .72). Fungal infections affected 10% of group 1 patients and 15% of group 2 patients (P = .71). Intraoperative complications were recorded in 27.6% of group 1 patients versus 54% of group 2 patients, a difference that was statistically significant (P = .032). CONCLUSIONS The study results supported the decision of our group to consider single lung transplantation the treatment of choice in emphysema, which may be complemented with volume reduction surgery in the native lung or subsequent transplantation of the contralateral lung.

Abstract
INTRODUCTION The major limiting factor for lung transplantation (LT), both worldwide and in Spain, is the number of suitable lung donors. This, together with the increased demand for LT, led us to propose the performance of 2 single lung transplantations simultaneously using the same donor (the "twinning procedure"). OBJECTIVE The objective of this study was to analyze the outcome of patients who underwent transplantation with this procedure, assessing differences between the first and the second transplant. PATIENTS AND METHODS From November 2001 to August 2008, 46 single lung transplantations (SLTs) were performed with 23 donors. RESULTS The mean ischemia time was 258 minutes (median, 265) for the first transplantation and 312 minutes (median, 320) for the second transplantation. Primary graft dysfunction occurred in 5 patients (24%) in the first group and 9 in the second group (39%; P = .27). The median intubation time was 8 hours for the first and 6.5 hours for the second group. The mean hospital stay was 39 and 31 days, respectively. Postoperative mortality was 2 (8.7%) and 3 (13%) patient, respectively (P = .99). There was no significant difference in the incidence of acute rejection episodes, infections, or chronic rejections. Five-year survival rates were 67.9% for the first and 61.5% for the second (Kaplan-Meier). CONCLUSIONS The performance of 2 SLTs using the same donor and in the same hospital was feasible with adequate planning, permitting better use of donors and reducing waiting list time and mortality. Our results showed no increased risk for recipients of the second transplant in the early postoperative and long-term periods.

Abstract
In Arabidopsis thaliana Columbia (Col-0) plants, the restriction of Tobacco etch virus (TEV) long-distance movement involves at least three dominant RTM (restricted TEV movement) genes named RTM1, RTM2, and RTM3. Previous work has established that, while the RTM-mediated resistance is also effective against other potyviruses, such as Plum pox virus (PPV) and Lettuce mosaic virus (LMV), some isolates of these viruses are able to overcome the RTM mechanism. In order to identify the viral determinant of this RTM-resistance breaking, the biological properties of recombinants between PPV-R, which systemically infects Col-0, and PPV-PSes, restricted by the RTM resistance, were evaluated. Recombinants that contain the PPV-R coat protein (CP) sequence in an RTM-restricted background are able to systemically infect Col-0. The use of recombinants carrying chimeric CP genes indicated that one or more PPV resistance-breaking determinants map to the 5' half of the CP gene. In the case of LMV, sequencing of independent RTM-breaking variants recovered after serial passages of the LMV AF199 isolate on Col-0 plants revealed, in each case, amino acid changes in the CP N-terminal region, close to the DAG motif. Taken together, these findings demonstrate that the potyvirus CP N-terminal region determines the outcome of the interaction with the RTM-mediated resistance.

Abstract
OBJECTIVE To assess the preoperative management in our emergency surgical service and to improve the quality of the care provided to patients. MATERIAL AND METHODS In order to find the causes of non-compliance, the Ishikawa Fishbone diagram was used and eight assessment criteria were chosen. The first assessment includes 120 patients operated on from January to April 2007. Corrective measures were implemented, which consisted of meetings and conferences with doctors and nurses, insisting on the importance of the informed consent as a legal document which must be signed by patients, and the obligation of giving a copy to patients or relatives. The second assessment includes the period from July to October 2007 (n=120). RESULTS We observed a high non-compliance of C1 signing of surgical consent (CRITERION 1: all patients or relatives have to sign the surgical informed consent for the operation to be performed [27.5%]) and C2 giving a copy of the surgical consent (CRITERION 2: all patients or relatives must have received a copy of the surgical informed consent for the Surgery to be performed [72.5%]) and C4 anaesthetic consent copy (CRITERION 4: all patients or relatives must have received a copy of the Anaesthesia informed consent corresponding to the operation performed [90%]). After implementing corrective measures a significant improvement was observed in the compliance of C2 and C4. In C1 there was an improvement without statistical significance. CONCLUSIONS The carrying out of an improvement cycle enabled the main objective of this paper to be achieved: to improve the management of informed consent and the quality of the care and information provided to our patients.

Abstract
Cathodoluminescence and photoluminescence techniques have been used to investigate room temperature light emission from beta-Ga(2)O(3):Eu nanostructures, which were obtained by two methods. In one of them, a mixture of Ga(2)O(3)/Eu(2)O(3) powders was used as precursor material and annealed under an argon flow. In the other one, undoped beta-Ga(2)O(3) nanostructures were first obtained by thermal oxidation of metallic gallium and europium was subsequently incorporated by a diffusion process. Room temperature luminescence at 610 nm due to Eu(3+) intraionic transitions from beta-Ga(2)O(3):Eu has been observed. Waveguiding of this red emitted light through the structures was shown.

Abstract
In vitro activity of fosfomycin, compared with other antibiotics used for urinary tract infections (UTI), against extended spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae clinical isolates obtained from UTIs, was determined. The activity of fosfomycin, co-trimoxazole, ciprofloxacin, nitrofurantoin, amoxicillin/clavulanic acid and gentamicin against 71 ESBL-producing E. coli clinical isolates and 13 ESBL-producing K. pneumoniae clinical isolates obtained from UTI was studied by the agar-dilution method or E-test. E. coli isolates produced mainly CTX-M type ESBL (76.1%), especially CTX-M 14 (56.3%). K. pneumoniae isolates produced most predominantly SHV-type ESBL (92.3%), mainly SHV-2 (76.9%). Gentamicin (4.4%), fosfomycin (5.6%) and nitrofurantoin (5.6%) showed the lowest resistance proportions against E. coli. Co-trimoxazole and ciprofloxacin (7.7%) showed the lowest resistance proportions against K. pneumoniae.

Abstract
Primary ovarian lymphoma is a rare entity. We submit a case of a 34-year-old black patient presenting with a bilateral adnexal tumor. She underwent hysterectomy with double salpingo-oophorectomy followed by polychemotherapy treatment. Histology confirmed Epstein-Barr virus-positive bilateral Burkitt's lymphoma. The patient died from septic shock after a month of treatment. Endemic Burkitt's lymphoma has a predilection for the female genital tract, manifesting itself clinically as a pelvic mass and less frequently as a menstrual disorder. It is a rare entity in our environment but should be kept in mind when treating patients of African origin.

Abstract
Hafnia alvei, a Gram negative bacillus related to the Enterobacteriaceae family, is considered an opportunistic pathogen of several animal species and humans. In this communication, we describe fimbrial-like structures from different strains of H. alvei that cannot be easily ascribed to any of the previously reported fimbrial types in this species (type I or type III). Polymerase chain reaction (PCR) and immunofluorescence assays were carried out to study fimbriae and flagella in H. alvei strains isolated from different sources. No correlation between the results obtained by PCR and those obtained by phenotypic methods were found, and the antibodies used gave cross or different recognition patterns of the surface structures present in these strains. We report as well that strain and growth temperature influence fimbriation and expression of flagella in human and animal isolates of H. alvei. This study also indicates that the absence of fimbriae have a significant positive influence on the initial adhesion of H. alvei to human epithelial cells.

Abstract
phi29 DNA-containing 12-13- particles (produced by infecting nonsuppressor hosts of Bacillus subtilis with phage containing suppressible mutations in cistrons 12 and 13) can be complemented with lysates containing proteins p12* and p13 to yield infectious phage. Complementation of these particles with lysates containing p12* but not p13 or complementation with purified p12* in the absence of p13 produces a structure (called complex) which has a markedly different organization. Electron microscopy and sedimentation analysis after digestion with DNase I or proteinase K indicate that complex is composed of an intact phage head with a genome-sized linear DNA molecule attached at the collar-tail region. EcoRI digestion establishes that the DNA molecule has a unique orientation. Gel electrophoresis indicates that p12*, the neck appendage protein, is transferred to the particles when complex is formed. Complex can also be produced by incubation of 12-13- particles at 42 degrees , by incubation at pH 6.0, or by incubation in the presence of 20 mM EDTA. Complex is also formed from DNA-containing 12- particles but to a lesser extent.

Abstract
We report the case of a 29-year-old man with hemoptysis. The patient came to the emergency department, where a laboratory test and chest radiograph were reported as normal. The following day the patient again had hemoptysis, though less than previously. He reported no chest pain, dyspnea, fever, catarrh, changes in urine or feces, contact with patients with bacillus disease or constitutional symptoms. Doppler ultrasound of the chest showed right basal parenchymatous condensation containing a vessel with arterial flow (in the opposite direction to the aortic flow) compatible with an aberrant vessel, possibly a sequestration, leaving the aorta above the celiac trunk. Because of the findings of the chest echogram and magnetic resonance study, thoracoabdominal computed tomography angiography was undertaken; this showed right basal condensation and an anomalous vessel originating 1 cm above the celiac trunk, supplying the right lower lobe. An aortic and pulmonary arteriogram via an arterial and right femoral vein approach confirmed the findings. The patient was treated successfully with percutaneous embolization with coils. The relevant literature is reviewed.

In January 2003 an automatic GC-FID analyzer of volatile organic compounds between 2 and 10 carbon atoms (C2-C10 VOCs) was placed in the centre of the Valderejo Natural Park in northern Iberia (42.87 degrees N, 3.22 degrees W), far away from important cities. The system operated continuously until December 2004. Data coverage was higher than 70% for a total of 59 VOC of both anthropogenic and biogenic origin, with detection limits in the range of pptv. Our results allow for the description of the behaviour of these compounds, in order to identify external impacts arriving to the sampling site which has been recognized to be highly representative of a rural background atmosphere. Biogenic VOC concentrations have been compared also with the calculated emissions, using Guenther's algorithm, and the discrepancies interpreted in terms of the different reactivity of such compounds.

Abstract
Plum pox virus (PPV) is a member of the genus Potyvirus that is able to infect a large variety of plant species, including trees of the genus Prunus, its natural host. When some PPV isolates are propagated for an extended time in herbaceous plants, their ability to infect trees is reduced. The molecular basis of this change in host infectivity is poorly understood. We report the construction of hybrid viruses from cDNA clones of two D-strain isolates of PPV, PPV-D and PPV-R, which differ in their host range. PPV-D can infect GF305 peach seedlings efficiently, however, it is unable to infect Nicotiana clevelandii plants. Conversely, PPV-R infects N. clevelandii, but not GF305 peach seedlings. The analyses of the hybrid viruses showed that, although determinants of PPV pathogenicity are extensively spread throughout the PPV genome, the 3' terminal region of the PPV-R genome, including the 3' noncoding region and the coding regions for the coat protein (CP), NIb, and part of NIa protein, is sufficient to confer infectivity of N. clevelandii in a PPV-D background. Our data demonstrate a high concentration of amino acid substitutions in the CP and a host-specific effect of a deletion at the N terminus of this protein in PPV pathogenicity in peach and N. clevelandii infectivity experiments. These results suggest that relevant host specificity determinants are located in the N-terminal region of the CP. The analyses of the PPV-R and PPV-D chimeras also showed that key host-specific pathogenicity determinants lie in the 5' terminal third of the PPV genome, a region that spans proteins P1, HCPro, and P3. The selection of mutations in only a few specific residues in proteins P1, P3, and 6K1 after partial adaptation of a chimeric virus (BD-GFP) to N. clevelandii further suggests a relevant role for these proteins in host adaptation.

Abstract
Cardiac and diaphragmatic mitochondria from male SAMP8 (senescent) and SAMR1 (resistant) mice of 5 or 10 months of age were studied. Levels of lipid peroxidation (LPO), glutathione (GSH), GSH disulfide (GSSG), and GSH peroxidase and GSH reductase (GRd) activities were measured. In addition, the effect of chronic treatment with the antioxidant melatonin from 1 to 10 months of age was evaluated. Cardiac and diaphragmatic mitochondria show an age-dependent increase in LPO levels and a reduction in GSH:GSSG ratios. Chronic treatment with melatonin counteracted the age-dependent LPO increase and GSH:GSSG ratio reduction in these mitochondria. Melatonin also increased GRd activity, an effect that may account for the maintenance of the mitochondrial GSH pool. Total mitochondrial content of GSH increased after melatonin treatment. In general, the effects of age and melatonin treatment were similar in senescence-resistant mice (SAMR1) and SAMP8 cardiac and diaphragmatic mitochondria, suggesting that these mice strains display similar mitochondrial oxidative damage at the age of 10 months. The results also support the efficacy of long-term melatonin treatment in preventing the age-dependent mitochondrial oxidative stress.

Abstract
Tobacco (Nicotiana tabaccum L.) is among the most important crops in La Vera Region (Cáceres, west-central Spain) where, since 2001, flue-cured tobacco plants showing typical symptoms of a vascular disease associated to the cyst nematode (Globodera tabacum) complex have been frequently observed (2). Symptoms observed were wilting, yellowing, and drying of the leaves, usually on one side of the plant; stunted and distorted leaves with curved midribs due to the unequal growth; and brown vascular discoloration of stems and midribs. Several diseased plants were collected during the summers of 2003 and 2004, and F. oxysporum was consistently isolated from sections of necrotic midribs. To confirm the pathogenicity of F. oxysporum isolates, plants of flue-cured tobacco (cv. Ct-681) were inoculated. Since Fusarium wilt of tobacco may be caused by F. oxysporum f. sp. vasinfectum or F. oxysporum f. sp. batatas (1), plants of cotton (cv. Acala) and sweet potato (cvs. Nemagold and Nancy Hall) were also inoculated to determine the forma specialis designation. Twenty plants per cultivar and isolate were inoculated with six isolates at the two to four true-leaf stage by pouring into the substrate 200 ml of a conidial suspension (1 × 105 CFU/ml). After inoculation, plants were incubated in a growth chamber at 28°C (day) and 24°C (night) with a 16-h photoperiod. All six F. oxysporum isolates were pathogenic to tobacco and sweet potato, but there were differences among isolates in time from inoculation to appearance of first disease symptoms (7 to 15 days after inoculation in tobacco and sweet potato) and also in disease severity 30 days after inoculation (60 to 100% wilt or mortality in tobacco and 50 to 100% in sweet potato). F. oxysporum was reisolated from stems of inoculated plants. No disease symptom was observed in cotton plants 60 days after inoculation, and F. oxysporum was not reisolated from them. Results of inoculation on the differential hosts indicated that disease symptoms in tobacco were caused by F. oxysporum f. sp. batatas. To our knowledge, this is the first report of F. oxysporum f. sp. batatas causing disease in flue-cured tobacco in Spain. References: (1) G. M. Armstrong and J. K. Armstrong.

Abstract
Cervical carcinoma (CC) is one of the most common cancers among women worldwide and the first cause of death among the Mexican female population. Human papillomavirus (HPV) infection is the most important etiologic factor for CC. Of the oncogenic types, HPV16 and HPV18 are found in 60-70% of invasive CCs worldwide. HPV18 appears to be associated with a more aggressive form of cervical neoplasia than HPV16 infection. At present, there are no studies on differentially expressed cellular genes between transformed cells harboring HPV16 and HPV18 sequences. Based on previous complementary DNA microarray data from our group, 13 genes were found to be differentially overexpressed between HPV16- and HPV18-transformed cells. These genes were as follows: E6BP, UBE4A, C20orf14, ATF7, ABCC8, SLC6A12, WASF3, SUV39H1, SPAG8, CCNC, E2FFE, BIRC5, and DEDD. Differential expression of six selected genes was confirmed by real-time reverse transcription-polymerase chain reaction (RT-PCR). All real-time RT-PCRs confirmed differential expression between HPV18 and HPV(-) samples. The present work identifies genes from signaling pathways triggered by HPV transformation that could be differentially deregulated between HPV16(+) and HPV18(+) samples.

Abstract
Fifty-four Holstein bulls were blocked by initial BW (301 +/- 7.4 kg) and randomly assigned to 6 treatments following a 3 x 2 factorial arrangement, with 3 concentrate lipid levels (5, 8, and 11% of DM) and 2 lipid sources (whole canola seed and whole linseed), with the objective of evaluating the possibility of increasing the content of n-3 fatty acids in meat. Concentrates (mostly corn meal) were isonitrogenous and isocaloric. Concentrate and straw were both fed ad libitum. Animal BW was recorded every 2 wk, and feed consumption was recorded weekly. Ruminal pH and VFA concentrations were determined monthly. Bulls were transported to the slaughterhouse when they achieved the target slaughter weight of 443 kg (after 105 +/- 4 d of fattening). After slaughter, a sample of LM from the sixth to the eighth ribs was dissected and analyzed for intramuscular fat content and fatty acid profile. Dietary lipid source did not affect overall animal performance, rumen fermentation, or carcass quality. Rumen pH was >6.0 despite consumption by the bulls of large amounts of concentrate. In bulls fed linseed, the percentage of n-3 fatty acids in LM increased linearly with lipid level, whereas in bulls fed canola seed it remained constant. The ratio of n-6:n-3 fatty acids was lower (P < 0.01) in the LM of bulls fed linseed (10.0) than in those fed canola seed (26.0). The content of cis-9, trans-11-CLA in the LM tended (P = 0.06) to be greater in the bulls fed linseed than in those fed canola seed (62.9 vs. 49.2 mg/kg of LM, respectively). Concentration of n-3 fatty acids in meat of bulls fed high-concentrate diets can be enhanced by whole linseed supplementation without affecting animal performance, ruminal fermentation, or carcass quality.

Abstract
Bronchiolitis obliterans organizing pneumonia (BOOP) is a clinicopathologic syndrome with characteristic features. The diagnosis of BOOP requires the presence of a combination of pathological, clinical, and radiological features. We report the case of a lung cancer patient with bronquiloalveolar carcinoma (BAC) presenting with BOOP after chemotherapy with docetaxel and gemcitabine producing severe respiratory insufficiency, and simulating a progression of the tumor.

Abstract
Twelve Arabidopsis accessions were challenged with Plum pox potyvirus (PPV) isolates representative of the four PPV strains. Each accession supported local and systemic infection by at least some of the PPV isolates, but high variability was observed in the behavior of the five PPV isolates or the 12 Arabidopsis accessions. Resistance to local infection or long-distance movement occurred in about 40% of all the accession-isolate combinations analyzed. Except for Nd-1, all accessions showed resistance to local infection by PPV-SoC; in the Landsberg erecta (Ler) accession, this resistance was compromised by sgt1 and rar1 mutations, suggesting that it could be controlled by an R gene-mediated resistance pathway. While most of the susceptible accessions were symptomless, PPV induced severe symptoms on inflorescences in C24, Ler, and Bay-0 as early as 15 days after inoculation. Genetic analyses indicated that these interaction phenotypes are controlled by different genetic systems. The restriction of long-distance movement of PPV-El Amar and of another member of genus Potyvirus, Lettuce mosaic virus, in Col-0 requires the RTM genes, indicating for the first time that the RTM system may provide a broad range, potyvirus-specific protection against systemic infection. The restriction to PPV-PS long-distance movement in Cvi-1 is controlled by a single recessive gene, designated rpv1, which was mapped to chromosome 1. The nuclear inclusion polymerase b-capsid protein region of the viral genome appears to be responsible for the ability of PPV-R to overcome rpv1-mediated resistance.

Abstract
The cylindrical inclusion (CI) protein of potyviruses is involved in virus replication and cell-to-cell movement. These two processes should rely on multiple plant-virus interactions; however, little is known about the host factors that are involved in, or that may interfere with, CI functions. By using a yeast two-hybrid system, the CI protein from Plum pox virus (PPV) was found to interact with the photosystem I PSI-K protein, the product of the gene psaK, of Nicotiana benthamiana. Coexpression of PPV CI was shown to cause a decrease in the accumulation level of PSI-K transiently expressed in N. benthamiana leaves. To test the biological relevance of this interaction, we have analyzed the infection of PPV in N. benthamiana plants in which psaK gene expression has been silenced by RNA interference, as well as in Arabidopsis thaliana psaK knockout plants. Our results show that downregulation of the psaK gene leads to higher PPV accumulation, suggesting a role for the CI-PSI-K interaction in PPV infection.

Abstract
There is little experience on the use of monoclonal antibodies that block the high-affinity interleukin-2 receptor (basiliximab and daclizumab) in sequential therapy in renal transplants with risk of delayed graft function. This study sougth to test the efficacy and safety of the substitution of anticalcineurins with two doses of basiliximab or daclizumab in the immediate posttransplant period for recipients at risk of delayed renal graft function. Immunosuppression consisted of steroids, mycophenolate mofetil, and two doses of basiliximab (20 mg/day) on days 0 and 4 posttransplant or daclizumab (1 mg/kg per day) on days 0 and 15 posttransplant. Anticalcineurins were not administered until the beginning of graft function. Among 49 recipients (mean age 63.5 +/- 10.5 years), 40 received a kidney from a donor over 60 years of age, three from a non-heart-beating donor, and six from donors with an acute elevation of serum creatinine to 2.4 +/- 0.86 (1.7-3.7). At a mean follow-up of 14.2 +/- 8.4 months, five patients experienced acute rejection episodes. Only 15 patients needed posttransplant dialysis (2.7 +/- 1.6). In 11 patients, cyclosporine (CsA) was introduced at 6 +/- 2.9 days posttransplant and in 37, tacrolimus on 8.6 +/- 3.6 days posttransplant. The incidence of kidney graft loss was 16.3%. Patient survival was 96%. Thirty-nine recipients are alive with functioning grafts, with mean serum creatinine of 1.4 mg/dL. In conclusion, substitution for anticalcineurins with interleukin-2-receptor blockade in the immediate posttransplant period for patients at risk of delayed graft function minimizes nephrotoxicity and reduces tubular necrosis, without increasing the risk of an acute rejection episode.

Trypanosoma vivax is the principal etiological agent of bovine trypanosomosis, a widely disseminated disease in tropical and subtropical regions. Here, we present a simple and reproducible method for the purification of T. vivax from experimentally infected and immunosuppressed sheep, using an isopycnic Percoll gradient, followed by DEAE-cellulose chromatography, with an estimated yield of 11-15%. This method could be used for the purification of T. vivax geographical isolates from various locations and from different natural hosts.

Abstract
Primary signet-ring cell carcinoma of the prostate is infrequent and even more so as secondary spread of this pathologic sub-type to the prostate. We describe the sixth reported case with a diagnosis of a secondary signet-ring cell tumour of the prostate secondary to a gastric cancer. Five years post-gastrectomy to resect signet-ring cell carcinoma, we detected a secondary intra-prostatic spread with urinary tract obstruction. The physical appearance of the tumour cells was similar to that of the previously-resected signet-cell carcinoma of the stomach. There were no metastases in other sites and the patient was treated with radiotherapy. When confronted with intra-prostatic signet-ring cell adenocarcinoma it is necessary to distinguish between primary and secondary aetiology since this would reflect in the choice of treatment and prognosis.

Abstract
Serine and threonine of many nuclear and cytoplasmic proteins are posttranslationally modified with O-linked N-acetylglucosamine (O-GlcNAc). This modification is made by O-linked N-acetylglucosamine transferases (OGTs). Genetic and biochemical data have demonstrated the existence of two OGTs of Arabidopsis thaliana, SECRET AGENT (SEC) and SPINDLY (SPY), with at least partly overlapping functions, but there is little information on their target proteins. The N terminus of the capsid protein (CP) of Plum pox virus (PPV) isolated from Nicotiana clevelandii is O-GlcNAc modified. We show here that O-GlcNAc modification of PPV CP also takes place in other plant hosts, N. benthamiana and Arabidopsis. PPV was able to infect the Arabidopsis OGT mutants sec-1, sec-2, and spy-3, but at early times of the infection, both rate of virus spread and accumulation were reduced in sec-1 and sec-2 relative to spy-3 and wild-type plants. By matrix-assisted laser desorption ionization-time of flight mass spectrometry, we determined that a 39-residue tryptic peptide from the N terminus of CP of PPV purified from the spy-3 mutant, but not sec-1 or sec-2, was O-GlcNAc modified, suggesting that SEC but not SPY modifies the capsid. While our results indicate that O-GlcNAc modification of PPV CP by SEC is not essential for infection, they show that the modification has a role(s) in the process.

Abstract
This article aims at improving the broadband ultraviolet radiometer's calibration methodology. For this goal, three broadband radiometers are calibrated against a spectrophotometer of reference. Three different one-step calibration models are tested: ratio, first order and second order. The latter is proposed in order to adequately reproduce the high dependence on the solar zenith angle shown by the other two models and, therefore, to improve the calibration performance at high solar elevations. The proposed new second-order model requires no additional information and, thus, keeps the operational character of the one-step methodology. The models are compared in terms of their root mean square error and the most qualified is subsequently validated by comparing its predictions with the spectrophotometer measurements within an independent validation data subset. Results show that the best calibration is achieved by the second-order model, with a mean bias error and mean absolute bias error lower than 2.2 and 6.7%, respectively.

Abstract
Gastrointestinal angiodysplasia is a very common cause of digestive hemorrhage among elderly patients with chronic renal insufficiency. Therapeutic possibilities are scarce, as well as information available. Here we present our experience with 8 cases of dialysis patients that were treated with conjugated estrogens because of digestive hemorrhage due to angiodysplasia. Dissapearance of bleeding was observed after the onset of estrogen therapy, with a significant decrease of blood transfusions. This type of non-invasive treatment can avoid aggressive therapeutic interventions in patients with a high prevalence of co-morbid conditions (old patients undergoing chronic dialysis).

Abstract
A wide range of visual parameters used to evaluate binocular function were evaluated in a paediatric population (1056 subjects aged 6-12 years). Mean values are provided for these ages in optometric tests that directly assess the vergence system, horizontal phorias for near and far vision (measured by a modified version of the Thorington method), negative and positive vergence amplitude for near and far vision (step vergence testing), vergence facility (flippers 8 Delta BI/8 Delta BO), and near-point of convergence (penlight push-up technique and red-lens push-up technique), as well as stimulus accommodative convergence/accommodation ratio and stereoacuity (Randot test) which provide an overall evaluation of the vergence, accommodative and oculomotor systems. A statistical comparison (anova and Bonferroni post hoc test) of these values between ages was performed. The differences, although statistically significant, were not clinically meaningful, and therefore we identified two trends in the behaviour of these parameters. For all parameters, except for vergence facility, we established a single mean reference value for the age range studied. The difference between the means for vergence facility indicated the need to divide the population into two age ranges (6-8 and 8-12 years). This study establishes statistical normal values for these parameters in a paediatric population and their means are a valuable instrument for separating children with binocular anomalies from those with normal binocular vision.

Abstract
UNLABELLED The renoprotective effect of renin-angiotensin system (RAAS) blockade by ACE inhibitors (ACEI) or AT1 receptor antagonists (ARA) in chronic proteinuric nephropathies is well known. Most studies have related this beneficial effect with the antihypertensive and antiproteinuric properties of these drugs, but this aspect has not been extensively analyzed in patients with normal/low values of blood pressure. We studied nineteen patients with different chronic proteinuric nephropathies that started ACEI or ARA because of proteinuria and despite systolic blood pressure (SBP) < or = 115 mmHg. Short and long-term tolerance to treatment as well as evolution of renal function parameters were recorded. RESULTS At baseline, SBP was 110.2 +/- 2.6 mmHg (105-115) an diastolic blood pressure (DBP) 68.6 +/- 4.3 (60-75). Initial low doses of ACEI or ARA were well tolerated. After 6 months of treatment, proteinuria decreased by 46% of baseline, from 2.1 +/- 1.8 g/day to 1.1 +/- 0.8 g/day, without significant changes in BP or renal function. After a 48 +/- 27 months follow up, proteinuria decreased to 0.7 +/- 0.6 g/day (68% of basal values). Renal function and BP did not show significant changes during follow up. CONCLUSIONS RAAS blockade by ACEI/ARA induces a significant antiproteinuric and renoprotective effect in proteinuric patients with normal/low levels of BP Initial doses of ACEI/ARA were well tolerated.

Abstract
We report a 75-years-old woman, stable on a three-weekly hemodialysis program over a period of 3 years, who develop acute hyperphosphatemia secondary to phosphate administration for bowel preparation. The quick clinical diagnosis and the treatment with intensive hemodialysis resulted in a correction of hyperphosphatemia, hypocalcemia, acidemia and other electrolyte abnormalities. The phosphate cathartics are contraindicated in patients with severe renal insufficient or in dialysis program. Our case shows the severe side effects secondary to injudicious use of sodium phosphate cathartics.

Abstract
The evolution of the accommodative function and development of ocular movement are evaluated in a non-clinical paediatric population (1056 subjects) aged 6-12 years, providing means for each age in the optometric tests that evaluate the accommodative amplitude, accommodative facility, accommodative response (lag), and saccadic movements. A comparison of these values between ages (anova) established three distinct trends in the behaviour of these parameters. The accommodative amplitude, measured by modified dynamic retinoscopy, and the evaluation of the saccadic movements by the development of ocular movements [developmental eye movement (DEM)] test showed continuous change with age. The values for monocular and binocular accommodative facility, measured by +/-2.00 D flippers, indicated the need to divide the population into two age groups (6-7 and 8-12 years). Finally, the means of accommodative response, measured by monocular estimation model (MEM) retinoscopy, and the direct observation of saccadic movement revealed no significant differences between ages, establishing a single mean reference value for the age group studied.

Abstract
PURPOSE To explore whether racial and ethnic concordance in the service patterns of residents is as disproportionate as it is among practicing physicians, and to examine the effect of residents' second-language proficiencies on these patterns. METHOD The authors conducted a cross-sectional study of billing data from 13,681 patient visits to resident continuity clinics at a Northern California pediatric medical center between May 1998 and October 1999. For each racial or ethnic group of patients, the proportion of patient visits to race-concordant residents was compared with the proportion of visits to all residents of other races or ethnicities. Multivariate logistic regression analyses (adjusted for confounders and residents' second-language proficiency) were used to measure the concordance of race or ethnicity in patient-resident pairs. RESULTS For all visits made to African-American, Asian, and Latino residents, the percentage of race-concordant visits exceeded the percentage of race-discordant visits for each patient group. In adjusted regression models, African-American, Asian, and Latino patients were more likely to visit residents of the same race or ethnicity. White patients were not more or less likely to visit white residents. When adjusted for residents' second-language proficiencies, Latino patients remained more likely to visit Latino residents and Asian patients remained more likely to see Asian residents. In analyses restricted to residents reporting fluency in Spanish, Latino patients were more likely to visit Latino residents. CONCLUSION African-American, Asian, and Latino pediatric residents disproportionately served more patients from their own racial or ethnic backgrounds. This service pattern was not completely explained by physicians' second-language proficiencies. A resident's race or ethnicity may reflect a unique set of skills that is highly valued by patients or health care systems.
