Abstract
Lead ammunition stands out as one of the most pervasive pollutants affecting wildlife. Its impact on bird populations have spurred efforts for the phase-out of leaded gunshot in several countries, although with varying scopes and applications. Ongoing and future policy changes require data to assess the effectiveness of adopted measures, particularly in the current context of biodiversity loss. Here, we assessed the long-term changes in blood lead (Pb) levels of Egyptian vultures from the Canary Islands, Spain, which have been severely affected by Pb poisoning over the past two decades. During this period, the reduction in hunting pressure and changes in legislation regarding firearms usage for small game hunting likely contributed to a decrease in environmental Pb availability. As anticipated, our results show a reduction in Pb levels, especially after the ban on wild rabbit hunting with shotgun since 2010. This effect was stronger in the preadult fraction of the vulture population. However, we still observed elevated blood Pb levels above the background and clinical thresholds in 5.6% and 1.5% of individuals, respectively. Our results highlight the positive impact of reducing the availability of Pb from ammunition sources on individual health. Nonetheless, the continued use of Pb gunshot remains an important source of poisoning, even lethal, mainly affecting adult individuals. This poses a particular concern for long-lived birds, compounding by potential chronic effects associated with Pb bioaccumulation. Our findings align with recent studies indicating insufficient reductions in Pb levels among European birds of prey, attributed to limited policy changes and their uneven implementation. We anticipated further reductions in Pb levels among Egyptian vultures with expanded restrictions on hunting practices, including a blanket ban on Pb shot usage across all small game species.

Abstract
A bearded vulture (Gypaetus barbatus) found dead in northern Spain presented external lesions consistent with electrocution as the cause of death. During forensic examination, macroscopic lesions suggested potential comorbidity, so samples were collected for molecular and toxicological analyses. Gastric content and liver were analysed for toxic substances, and pentobarbital (a common pharmaceutical used for euthanasia in domestic animals) was detected at a concentration of 37.3 and 0.05 µg/g, respectively. Other toxicological, viral and endoparasite analyses (avian malaria, avian influenza and flaviviruses) were negative. Thus, although the cause of death was electrocution, pentobarbital intoxication likely impaired the equilibrium and reflexes of the individual, possibly causing the bird to contact energized wires that it would not have otherwise. These results underline the importance of comprehensive analysis of forensic cases of wildlife deaths and reveal barbiturate poisoning as an additional threat for the conservation of the bearded vulture in Europe.

Abstract
BACKGROUND Blood loss is a major determinant of outcomes following hepatectomy. Robotic technology enables hepatobiliary surgeons to mimic open techniques for inflow control and parenchymal transection during major hepatectomy, increasing the ability to minimize blood loss and perform safe liver resections. METHODS Initial experience of 20 consecutive major robotic hepatectomies from November 2018 to July 2020 at two co-located institutions was reviewed. All cases were performed with extrahepatic inflow control and parenchymal transection with the laparoscopic cavitron ultrasonic surgical aspirator (CUSA), and a technical description is illustrated. Clinical characteristics, operative data, and surgical outcomes were retrospectively analyzed. RESULTS The median (range) patient age was 58 years (20-76) and the majority of 14 (70%) patients were ASA III-IV. There were 12 (60%) resections for malignancy and the median tumor size was 6.2 cm (1.2-14.6). Right or extended right hepatectomy was the most common procedure (12 or 60% of cases). There were 7 (35%) left or extended left hepatectomies and 1 (5%) central hepatectomy. The median operative time was 420 (177-622) minutes. Median estimated blood loss was 300 mL (25-800 mL). One (5%) case was converted to open. Two (10%) patients required blood transfusion. The median length of stay was 3 (1-6) days. Major complications included 1 (5%) Clavien-Dindo IIIa bile leak requiring percutaneous drainage placement. There was no 90-day mortality. CONCLUSION Advanced techniques to reduce blood loss in robotic hepatectomy may optimize safety and minimize morbidity in these complex minimally invasive procedures.

Abstract
The active role of gastrointestinal microbiota in mercury (Hg) methylation has been investigated in different terrestrial organisms from insects or annelids to rats and mammals, including the human beings. Some findings reveal the animal digestive tracts as new potential niches for Hg methylation especially in terrestrial invertebrates. However, contradictory results have been reported so far and there is still a long way to fully understand how important the MeHg production in this habitat could be, as well as its implications on the toxicity and biomagnification of MeHg within terrestrial food chains. It is important to know what has been studied in the past and discuss the previous results according to the new perspectives opened in this field. Therefore, the aim of this work is to review the present state of knowledge about the potential capability of gastrointestinal microbiota in Hg methylation with special emphasis in terrestrial animals and to propose new approaches profiting the new and powerful molecular and analytical tools.

Abstract
PURPOSE Hyperglycemia increases risks of kidney and liver transplant rejection. To determine whether perioperative and subsequent glycemic control was associated with increased risk of heart transplant rejection over the year after transplantation, we performed a retrospective analysis of glycemic control and rejection rates in heart transplantation patients. METHODS Perioperative glucose levels were analyzed in 157 patients undergoing transplantation at Northwestern Memorial Hospital from June 2005 to December 2012 and compared in patients with and without rejection found on routine follow-up biopsy specimens. RESULTS Grade ≤1R rejection on biopsy was observed in 116 patients and grade ≥2R rejection (grade requiring increased anti-rejection treatment) in 41 patients. Although no significant differences in the preoperative fasting or inpatient mean glucose levels were found, the mean glucose levels from discharge to 1 year trended higher in those with grade ≥2R compared to grade ≤1R (128.8 ± 40.9 versus 142.2 ± 46.6 mg/dL, P = .084). In a multivariable logistic regression model, neither the lowest nor highest quartile of glucose levels had significantly different odds ratios (ORs) for the development of ≥2R compared to the middle 50% glucose levels. Older age (OR 0.96, P = .020) and higher body mass index levels (OR 0.86, P = .004) were significantly associated with lower odds of developing grade ≥2R. CONCLUSIONS Although the glucose trend regarding rejection was not statistically significant, we cannot exclude the possibility that much higher glucose levels would influence rejection rates.

Abstract
Biomonitoring using birds of prey as sentinel species has been mooted as a way to evaluate the success of European Union directives that are designed to protect people and the environment across Europe from industrial contaminants and pesticides. No such pan-European evaluation currently exists. Coordination of such large scale monitoring would require harmonisation across multiple countries of the types of samples collected and analysed-matrices vary in the ease with which they can be collected and the information they provide. We report the first ever pan-European assessment of which raptor samples are collected across Europe and review their suitability for biomonitoring. Currently, some 182 monitoring programmes across 33 European countries collect a variety of raptor samples, and we discuss the relative merits of each for monitoring current priority and emerging compounds. Of the matrices collected, blood and liver are used most extensively for quantifying trends in recent and longer-term contaminant exposure, respectively. These matrices are potentially the most effective for pan-European biomonitoring but are not so widely and frequently collected as others. We found that failed eggs and feathers are the most widely collected samples. Because of this ubiquity, they may provide the best opportunities for widescale biomonitoring, although neither is suitable for all compounds. We advocate piloting pan-European monitoring of selected priority compounds using these matrices and developing read-across approaches to accommodate any effects that trophic pathway and species differences in accumulation may have on our ability to track environmental trends in contaminants.

Abstract
The impact of mercury (Hg) pollution in the terrestrial environments and the terrestrial food chains including the impact on human food consumption is still greatly under-investigated. In particular, studies including Hg speciation and detoxification strategies in terrestrial animals are almost non-existing, but these are key information with important implications for human beings. Therefore, in this work, we report on Hg species (inorganic mercury, iHg, and monomethylmercury, MeHg) distribution among terrestrial animal tissues obtained from a real-world Hg exposure scenario (Almadén mining district, Spain). Thus, we studied Hg species (iHg and MeHg) and total selenium (Se) content in liver and kidney of red deer (Cervus elaphus; n = 41) and wild boar (Sus scrofa; n = 16). Similar mercury species distribution was found for both red deer and wild boar. Major differences were found between tissues; thus, in kidney, iHg was clearly the predominant species (more than 81%), while in liver, the species distribution was less homogeneous with a percentage of MeHg up to 46% in some cases. Therefore, Hg accumulation and MeHg transfer were evident in terrestrial ecosystems. The interaction between total Se and Hg species has been evaluated by tissue and by animal species. Similar relationships were found in kidney for both Hg species in red deer and wild boar. However, in liver, there were differences between animals. The possible underlying mechanisms are discussed.

Abstract
Biomonitoring using raptors as sentinels can provide early warning of the potential impacts of contaminants on humans and the environment and also a means of tracking the success of associated mitigation measures. Examples include detection of heavy metal-induced immune system impairment, PCB-induced altered reproductive impacts, and toxicity associated with lead in shot game. Authorisation of such releases and implementation of mitigation is now increasingly delivered through EU-wide directives but there is little established pan-European monitoring to quantify outcomes. We investigated the potential for EU-wide coordinated contaminant monitoring using raptors as sentinels. We did this using a questionnaire to ascertain the current scale of national activity across 44 European countries. According to this survey, there have been 52 different contaminant monitoring schemes with raptors over the last 50years. There were active schemes in 15 (predominantly western European) countries and 23 schemes have been running for >20years; most monitoring was conducted for >5years. Legacy persistent organic compounds (specifically organochlorine insecticides and PCBs), and metals/metalloids were monitored in most of the 15 countries. Fungicides, flame retardants and anticoagulant rodenticides were also relatively frequently monitored (each in at least 6 countries). Common buzzard (Buteo buteo), common kestrel (Falco tinnunculus), golden eagle (Aquila chrysaetos), white-tailed sea eagle (Haliaeetus albicilla), peregrine falcon (Falco peregrinus), tawny owl (Strix aluco) and barn owl (Tyto alba) were most commonly monitored (each in 6-10 countries). Feathers and eggs were most widely analysed although many schemes also analysed body tissues. Our study reveals an existing capability across multiple European countries for contaminant monitoring using raptors. However, coordination between existing schemes and expansion of monitoring into Eastern Europe is needed. This would enable assessment of the appropriateness of the EU-regulation of substances that are hazardous to humans and the environment, the effectiveness of EU level mitigation policies, and identify pan-European spatial and temporal trends in current and emerging contaminants of concern.

Abstract
Context
Cereal pellets containing the anti-coagulant poison brodifacoum at 20 ppm are routinely used to rid islands of invasive rodents. The impact, if any, of the poison on invertebrates is not well understood. This is problematic because many of the islands targeted for treatment harbour endemic invertebrate species, including snails where available information about brodifacoum impact is equivocal.
Aims
Combining field tests and subsequent laboratory analysis, the present study investigated the effect of brodifacoum on the snails of Henderson Island, South Pacific.
Methods
In the field, we housed snails in plastic boxes for up to 10 days to compare the survival of those kept with and without access to brodifacoum cereal pellets. Subsequently, we analysed brodifacoum levels in those kept with access to poisoned pellets, according to whether they survived or died.
Key results
There were no detectable differences in the survival between the captive snails kept with and those kept without access to brodifacoum. Among those with access, there were no significant differences in brodifacoum concentrations between the minority that died and the majority that survived. In fact, brodifacoum was detected in only a few samples.
Conclusions
Brodifacoum appears not to pose a risk to the snails of Henderson Island.
Implications
Although it would be prudent to test the impact of brodifacoum on the resident snails before proceeding with a rodent eradication on other islands, we suspect the Henderson results can be extended to other sites.

Abstract
Hunted mallards (n = 56) were collected in the Ebro Delta (Spain) in 2007-08 to evaluate the use of feces as a non-invasive monitoring method to study lead shot ingestion. The prevalence of Pb shot ingestion in these birds was 28.6%, and similar to that reported before a ban on Pb shot use in 2003. Lead concentrations in terminal intestinal contents were higher in mallards with Pb shot in their gizzard. Feces Pb concentrations >34 microg/g d.w were indicative of Pb shot ingestion, and background Pb levels were <12.5 microg/g d.w. To discriminate between birds ingesting soil Pb, and those ingesting Pb shot, we correlated Al and Pb levels and showed that mallards with ingested Pb shot in the gizzard stood out as outliers within the regression. Feces Pb-Al relationships can be used as a simple non-invasive tool in monitoring programs regarding Pb shot ingestion in birds.

Abstract
A common vole (Microtus arvalis) population peak in Northern Spain in 2007 was treated with large scale application of chlorophacinone, an anticoagulant rodenticide of the indandione family. Voles found dead and trapped alive were collected in treated and untreated areas. Residues of chlorophacinone were analyzed in liver of voles by HPLC-UV. Also, the presence of the pathogen Francisella tularensis was analyzed by PCR in samples of vole spleen. Chlorophacinone (82-3800 ng/g; wet weight liver) was only detected in voles found dead in treated areas (55.5%). The prevalence of F. tularensis in voles found dead in treated areas was also particularly high (66.7%). Moreover, chlorophacinone levels were lower in voles that were PCR-positive for F. tularensis (geometric mean [95% CI], 418 [143-1219] ng/g) than in those that were PCR-negative (1084 [581-2121] ng/g). Interactions between pathogens and rodenticides might be considered to reduce the doses used in baits or to avoid the use of the more toxic 2nd generation anticoagulant rodenticides.

Abstract
Arsenic is known to accumulate with iron plaque on macrophyte roots. Three to four years after the Aznalcóllar mine spill (Spain), residual arsenic contamination left in seasonal wetland habitats has been identified in this form by scanning electron microscopy. Total digestion has determined arsenic concentrations in thoroughly washed 'root+plaque' material in excess of 1000 mg kg(-1), and further analysis using X-ray absorption spectroscopy suggests arsenic exists as both arsenate and arsenite. Certain herbivorous species feed on rhizomes and bulbs of macrophytes in a wide range of global environments, and the ecotoxicological impact of consuming arsenic rich iron plaque associated with such food items remains to be quantified. Here, greylag geese which feed on Scirpus maritimus rhizome and bulb material in areas affected by the Aznalcóllar spill are shown to have elevated levels of arsenic in their feces, which may originate from arsenic rich iron plaque.

Abstract
Lead mining in the Sierra Madrona mountains and the valley of Alcudia in Southern Spain began in the 1st millennium B.C., and the area was intermittently exploited up until the end of the 20th century. The degree of contamination by Pb, Zn, Cd, Cu, As and Se of soil, water and sediment, and the transfer to 13 species of plants, and then to red deer (Cervus elaphus) have been studied. Mined areas had higher concentrations in stream sediments than control areas. The highest concentrations were observed for Pb (1481 microg g(-1) d.w.) and As (1880 microg g(-1)) in the sediment of a stream flowing beside the spoil dump at Mina de Horcajo. Plants from mining sites contained consistently higher levels of Pb and As, and their concentrations in plants were correlated. The highest concentrations of Pb were in Gramineae (Pb: 97.5, As: 2.4 microg g(-1) d.w.), and the lowest in elmleaf blackberry (Rubus ulmifolius). The highest mean liver concentrations were found in red deer from the mining sites for Pb (0.805 microg g(-1) d. w.), Cd (0.554 microg g(-1)), Se (0.327 microg g(-1)), and As (0.061 microg g(-1)), although these were well below the levels associated with clinical poisoning.

Abstract
The oxidation handicap hypothesis proposes that testosterone mediates the trade-off between the expression of secondary sexual traits and the fight against free radicals. Coloured traits controlled by testosterone can be produced by carotenoid pigments (yellow-orange-red traits), but carotenoids also help to quench free radicals. Recently, it has been shown that testosterone increases the amount of circulating carotenoids in birds. Here, a testosterone-mediated trade-off in the carotenoid allocation between colour expression and the fight against oxidative stress is proposed. Male red-legged partridges were treated with testosterone, anti-androgens or manipulated as controls. Testosterone-treated males maintained the highest circulating carotenoid levels, but showed the palest red traits and no evidence of oxidative damage. Increased levels of a key intracellular antioxidant (i.e. glutathione) indicated that an oxidative challenge was in fact induced but controlled. The trade-off was apparently solved by reducing redness, allowing increased carotenoid availability, which could have contributed to buffer oxidative stress.

Abstract
Fusarium graminearum is a mould that causes serious diseases in cereals worldwide and that synthesises mycotoxins such as deoxynivalenol (DON), which can seriously affect human and animal health. Predicting the level of mycotoxin accumulation in food is very difficult, because of the complexity of the influencing parameters. In this work, we have studied the possibility of using artificial neural networks (NN) to predict DON level attained in F. graminearum wheat cultures taking as inputs the fungal contamination level of the cereal, the water activity as a measure of the available water for fungal growth in the cereal, the temperature and time. DON analysis was performed by gas chromatography with electron capture detection. The data matrix was used to train and validate various types of NN using MATLAB 7.0. The aim was to obtain a network that provided the best possible fit between predicted and target DON levels by minimising the mean-square error of test. Radial basis function-NNs attained lower errors and better generalisation than multi-layer perceptron networks to predict DON accumulation in wheat. This is the first time that NNs have been used to predict DON accumulation in wheat based on the studied factors.

Abstract
The Iberian lynx (Lynx pardinus) is the most endangered felid in the world with a wild population which probably stands at less than 200 individuals inhabiting two areas in Southern Spain (Doñana and Sierra Morena) that are known to have been contaminated by heavy metals and metalloids due to a long history of mining activities. This contamination may pose a threat to long term conservation efforts and hence, the concentrations of seven elements (As, Se, Cd, Zn, Cu, Pb, Hg) were determined in the liver, muscle and bone of 9 lynx, as well as 17 red foxes (Vulpes vulpes), 11 Egyptian mongooses (Herpestes ichneumon), 4 common genets (Genetta genetta) and 1 Eurasian badger (Meles meles). The mean concentrations found were below the threshold levels indicative of chronic intoxication in all the species studied. In general, genet and red fox were species with the highest concentrations of several elements in Doñana, whilst Iberian lynx had the lowest levels of most of them. Lynx from Sierra Morena had significantly higher concentrations of bone Pb (2.05 microg/g d.w.) than those from Doñana (0.13 microg/g d.w.), probably due to the mineralised underlying geology and/or the abandoned mine workings in Sierra Morena. Egyptian mongoose presented liver concentrations of Hg up to 9.7 microg/g d.w. A strong relationship between Hg and Se levels was found in liver and muscle samples of all the studied species, especially in mongoose. In conclusion, levels of the studied elements do not appear to represent a significant threat for the lynx or for the other carnivores studied. However, given the critical status of the Iberian lynx, a continuous monitoring scheme remains necessary.

Abstract
INTRODUCTION Significant malnutrition exists in a high percentage of patients with head and neck cancer. Malnutrition is associated with defects in immune function that may impair the host response to malignancy. Malnutrition and immunosupression make patients highly susceptible to postoperative infections and complications. OBJECTIVES Compare two immunoenhanced enteral nutritions with a control diet, and evaluate the effect in postoperative infections, length of stay and inflammatory markers. PATIENTS A population of 44 patients with oral and laryngeal cancer was enrolled in a randomized trial. At surgery, patients were randomly allocated to three groups: (group I); patients receiving an arginine-enhanced formula (group II); patients receiving a standard polymeric formula, and (group III) patients receiving an arginine, RNA and omega-3 fatty acids enhanced formula, in an isonitrogenous way. RESULTS The duration of enteral nutrition in the three groups was similar with an average duration of 14,5 +/- 8 days. The length of postoperative stay was similar, with an average of 19,8 +/- 8,5 days. Wound infections and general infections were more frequent in the control group. Fistula rates were not improved in the enhanced diet groups. No significant intergroup differences in the trend of the two plasma proteins (albumin, transferrin), lymphocytes, weight, IL-6, CPR and TNFalpha were detected. The control group showed the highest levels of TNFalpha at the fourteenth postoperative day. Gastrointestinal tolerance and diarrhoea rate were similar in all the patients. CONCLUSIONS Immunoenhanced enteral nutrition formulas improved the infection rate in the postoperative of head and neck cancer patients. In the fistula rates, we observed that technical problems and nutritional status might have played an equally important role, and therefore the positive effect of immunonutrition in this parameter might have been overestimated.

Abstract
Tumor markers such as carbohydrate antigen 19-9 (CA 19-9) are commonly measured in the serum of patients with suspected pancreaticobiliary malignancies. Moderate elevations of CA 19-9 may be seen in benign disease, but levels in the thousands are indicative of malignancy. We report the case of a 64-year-old man with an elevated CA 19-9 of 5791 U/ml and radiological findings suggestive of metastatic gallbladder carcinoma. The patient underwent cholecystectomy and excision of a common bile duct stricture, with hepaticojejunostomy and liver biopsy. The final surgical pathology was consistent with xanthogranulomatous cholecystitis (XGC) and the elevated CA 19-9 returned to normal postoperatively. Thus, an elevated CA 19-9 level, even in the thousands, should not preclude patients from an operation if a mass is deemed resectable. Thorough investigation and treatment may result in a curative operation even if unresectable malignant disease is initially suspected.

Abstract
We studied lead (Pb) shot contamination in sediments from the Guadalquivir marshes and six other closed-basin lagoons in Southern Spain that are of major importance for threatened species of waterbirds. Shot densities were relatively low in Doñana, ranging from 0 to 25 shot/m(2) in the top 10 cm of sediments. The density at Medina lagoon (Ramsar site) was 148 shot/m(2), making it the most contaminated wetland known in Europe. Densities in the other five lagoons ranged from 9 to 59 shot/m(2). We studied the prevalence of ingested Pb shot in waterbirds from Doñana and found a lower prevalence in ducks than previously recorded in other Spanish wetlands. Lead shot were also found embedded in tissues of some waterbirds, proving that protected species such as the greater flamingo (Phoenicopterus ruber) and the glossy ibis (Plegadis falcinellus) are subjected to illegal hunting. The prevalence of embedded shot for geese was especially high (44% for trapped birds). Lead shot were detected in 2.8% of the pellets of the Spanish imperial eagle (Aquila adalberti) which usually preys on geese. We found that the prevalence of ingested Pb shot in geese and in Spanish imperial eagles has significantly decreased in recent years, possibly due to restrictions on hunting activity, efforts to remove shot from a sand dune used by geese to obtain grit, and to the high rainfall in Doñana during the last years that permitted waterfowl to stay more within the protected areas.

Abstract
We evaluated the transfer of Pb from shot to meat during the preparation of breasts of quails with 0, 1, 2 or 4 embedded Pb shot. A traditional Spanish recipe was used which utilizes vinegar during cooking to enhance the long-term preservation of the meat. The effect of the acidic conditions generated by the vinegar on Pb transfer was compared with the same recipe when the vinegar was substituted with water. The effect of up to 4 weeks of storage on Pb transfer has been also evaluated. The transfer of Pb from the embedded shot to the meat was much higher when cooking with vinegar than with water. However, the Pb transfer under acidic conditions did not increase significantly during long-term storage at room temperature. The consumption of only half a pickled quail per week with embedded shot may cause the provisional tolerable weekly intake (PTWI) of Pb by the Spanish consumer to be exceeded.

Abstract
BACKGROUND Celiac axis invasion by central and distal pancreatic cancers has been considered a contraindication to resection. Appleby first described en-bloc celiac axis resection with total gastrectomy for locally advanced gastric cancer. We present our experience with a modification of this procedure in central pancreatic cancers involving the celiac trunk. METHODS Three patients with central pancreatic cancers invading the celiac axis are reviewed. All patients underwent extended pancreatectomy with en-bloc resection of the celiac axis. RESULTS Margins were grossly clear of tumor in all patients. The mean length of stay was 8.3+/-1.1 days. There was no evidence of clinically significant gastric or hepatic ischemia. All 3 patients remain disease free at 34, 14, and 14 months from surgery, respectively. COMMENTS Extended pancreatectomy with celiac axis resection can result in prolonged survival and should be considered in central and distal pancreatic cancers invading the celiac trunk.

Abstract
The chronic shortage of deceased kidney donors has led to increased utilization of donation after cardiac death (DCD) kidneys, the majority of which are procured in a controlled setting. The objective of this study is to evaluate transplantation outcomes from uncontrolled DCD (uDCD) donors and evaluate their utility as a source of donor kidneys. From January 1995 to December 2004, 75,865 kidney-alone transplants from donation after brain death (DBD) donors and 2136 transplants from DCD donors were reported to the United Network for Organ Sharing. Among the DCD transplants, 1814 were from controlled and 216 from uncontrolled DCD donors. The log-rank test was used to compare survival curves. The incidence of delayed graft function in controlled DCD (cDCD) was 42% and in uDCD kidneys was 51%, compared to only 24% in kidneys from DBD donors (p < 0.001). The overall graft and patient survival of DCD donors was similar to that of DBD donor kidneys (p = 0.66; p = 0.88). Despite longer donor warm and cold ischemic times, overall graft and patient survival of uDCD donors was comparable to that of cDCD donors (p = 0.65, p = 0.99). Concerted efforts should be focused on procurement of uDCD donors, which can provide another source of quality deceased donor kidneys.

Abstract
In the present report, a total of 75 Fusarium spp isolates (35 of the Gibberella fujikuroi species complex, 26 of F. oxysporum, 7 of F. graminearum, 5 of F. culmorum, 1 of F. cerealis, and 1 of F. poae) from different hosts were characterized morphologically, physiologically and genetically. Morphological characterization was performed according to macroscopic and microscopic aspects. Physiological characterization was based on their ability to produce fumonisin B1 (FB1), fumonisin B2 (FB2), zearalenone (ZEA) and type B trichothecenes (deoxynivalenol, nivalenol and 3-acetyldeoxynivalenol). FB1, FB2, and ZEA were determined by liquid chromatography and trichothecenes by gas chromatography. Molecular characterization of isolates was carried out using an optimized and simple method for isolation of DNA from filamentous fungi and polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) of the intergenic spacer region (IGS) of the rDNA. The results indicated that G. fujikuroi complex isolates can be divided into low and high fumonisin producers. The haplotypes obtained with HhaI, EcoRI, AluI, PstI and XhoI enzymes provided very characteristic groupings of G. fujikuroi isolates as a function of host type and fumonisin producing capacity. F. graminearum, F. culmorum and F. cerealis isolates were high ZEA and type B trichothecene producers, while F. oxysporum and the G. fujikuroi complex isolates did not show this ability. The haplotypes obtained with CfoI, AluI, HapII, XhoI, EcoRI and PstI enzymes permitted to discern these five Fusarium species and G. fujikuroi complex isolates but the restriction patterns of the IGS region did not show any relationship with the geographic origin of isolates.

Abstract
Due to increasing use of allografts from donation after cardiac death (DCD) donors, we evaluated DCD liver transplants and impact of recipient and donor factors on graft survival. Liver transplants from DCD donors reported to UNOS were analyzed against donation after brain death (DBD) donor liver transplants performed between 1996 and 2003. We defined a recipient cumulative relative risk (RCRR) using significant risk factors identified from a Cox regression analysis: age; medical condition at transplantation; regraft status; dialysis received and serum creatinine. Graft survival from DCD donors (71% at 1 year and 60% at 3 years) were significantly inferior to DBD donors (80% at 1 year and 72% at 3 years, p < 0.001). Low-risk recipients (RCRR < or = 1.5) with low-risk DCD livers (DWIT < 30 min and CIT < 10 h, n = 226) achieved graft survival rates (81% and 67% at 1 and 3 years, respectively) not significantly different from recipients with DBD allografts (80% and 72% at 1 and 3 years, respectively, log-rank p = 0.23). Liver allografts from DCD donors may be used to increase the cadaveric donor pool, with favorable graft survival rates achieved when low-risk grafts are transplanted in a low-risk setting. Whether transplantation of these organs in low-risk recipients provides a survival benefit compared to the waiting list is unknown.

Abstract
Fumonisin B1 (FB1) and fumonisin B2 (FB2) are the main members of a family of mycotoxins produced by various fungal species belonging to the Gibberella fujikuroi complex. The present work shows the results of a comparative study of various clean-up and derivatization procedures for analysis of fumonisins in rice cultures. Fumonisins were extracted from rice with acetonitrile/water (50/50, v/v). For clean-up, three solid-phase extraction procedures were assayed (C18 cartridge, SAX cartridge, and a combination of both). Two reagents (o-phthaldialdehyde and 4-fluoro-7-nitro-benzofurazan) were studied comparatively for formation of fluorescent derivatives. The separation was carried out by LC using a fluorescence detector. The best procedure for analysis of fumonisins in rice involved clean-up with C18 cartridge and derivatization with o-phthaldialdehyde. The limit of detection was 0.010 mg kg(-1) for both toxins. In the 10-500 mg kg(-1) spiking level range, the recovery rates for FB1 and FB2 in rice varied from 94.6% to 103.6% and from 96.3% to 101.9%, respectively. The optimized analytical method for determination of fumonisins in rice was applied to the study of FB1 and FB2 production by four isolates of the G. fujikuroi species complex in rice cultures carried out at different temperatures and water activities to establish the influence of strain and environmental conditions on fumonisin production in this cereal. In general, fumonisin production was the highest at 20 degrees C and lowest at 37 degrees C. Four of the five assayed water activity (aw) values (0.97, 0.98, 0.99, and 1.0) did not affect significantly fumonisin accumulation but fumonisins were not detected in cultures when aw was 0.96.

Abstract
In April 1998, a holding lagoon containing pyrite ore processing waste, failed and released 5-6 million m3 of highly polluting sludge and acidic water. Over 2650 ha of the internationally important Doñana Natural Park became contaminated, along with < 100 ha of the more pristine Doñana National Park. In order to assess the affect of the spill on waterfowl from Doñana, bone and liver samples from 124 individuals have been analysed for As, Pb, Cu, Zn and Se. Five species have been studied, from the Rallidae (rails), Anatini (dabbling ducks) and Aythyini (pochards) families. Geometric mean bone concentrations 2-3 months after the spill were in the order of Zn > Cu > Pb > Se > As, while liver concentrations were in the order of Zn > Cu > Se > Pb > As. Dry weight bone concentrations ranged from n.d-1.76 mg kg(-1) As, 109.4-247.6 mg kg(-1) Zn, 0.06-1.27 mg kg(-1) Se, n.d-134.11 mg kg(-1) Pb, and 2.18-8.92 mg kg(-1) Cu. Wet weight liver concentrations ranged from n.d-0.34 mg kg(-1) As, 29.8-220.1 mg kg(-1) Zn, 0.15-0.85 mg kg(-1) Se, n.d-3.80 mg kg(-1) Pb, and 7.30-742.96 mg kg(-1) Cu. The most important factor related to the accumulation of these metals was commonly species; however, location and sex also had important effects on liver As levels, location and age affected Cu levels, while Zn and Pb were affected by age, sex and location. Birds from Natural Park areas were found to have significantly higher levels of bone Zn, Pb and Cu, and liver As and Cu than birds from National Park areas. Female birds had higher liver As, Zn and Pb than males; whilst adults appeared to have lower bone As and Zn but higher liver Pb than chicks/juveniles. Although metal concentrations were elevated in certain individuals, in the majority of birds studied, they did not reach levels widely considered to be toxic. However, it would appear that As and Cu liver levels (which may be indicative of short-medium term pollutant exposure) were elevated in waterbirds which died in the spill contaminated Natural Park, 2-3 months after the disaster.

Abstract
BACKGROUND Sirolimus is a potent immunosuppressive agent whose role in liver transplantation has not been well-described. AIM To evaluate the efficacy and side-effects of sirolimus-based immunosuppression in liver transplant patients. METHODS Retrospective analysis of 185 patients who underwent orthotopic liver transplantation. Patients were divided into three groups: group SA, sirolimus alone (n = 28); group SC, sirolimus with calcineurin inhibitors (n =56) and group CNI, calcineurin inhibitors without sirolimus (n = 101). RESULTS One-year patient and graft survival rates were 86.5% and 82.1% in group SA, 94.6% and 92.9% in group SC, and 83.2% and 75.2% in group CNI (P = N.S.). The rates of acute cellular rejection at 12 months were comparable among the three groups. At the time of transplantation, serum creatinine levels were significantly higher in group SA, but mean creatinine among the three groups at 1 month was similar. More patients in group SA required dialysis before orthotopic liver transplantation (group SA, 25%; group SC, 9%; group CNI, 5%; P = 0.008), but at 1 year, post-orthotopic liver transplantation dialysis rates were similar. CONCLUSIONS Sirolimus given alone or in conjunction with calcineurin inhibitors appears to be an effective primary immunosuppressant regimen for orthotopic liver transplantation patients. Further studies to evaluate the efficacy and side-effect profile of sirolimus in liver transplant patients are warranted.

Abstract
BACKGROUND Pseudoaneurysms of the extrahepatic arterial vasculature are relatively uncommon lesions following surgery and trauma. In this report we analyze the presentation, management and outcomes of these vascular lesions. Of the related surgical procedures, the reported incidence is highest following laparoscopic cholecystectomy. We hereby analyze the literature on this subject and report our experience, specifically with extrahepatic pseudoaneurysms, drawing an important distinction from intrahepatic pseudoaneurysms. METHODS From September 1995 until July 2004, six patients, including three males and three females with a mean age of 67 years, were treated for seven extrahepatic arterial pseudoaneurysms. Patients were evaluated by endoscopy, ultrasound, computerized tomography, and angiography. Management included coil embolization or arterial ligation and/or hepatic resection. RESULTS The mean pseudoaneurysm size was 4.9-cm (range 1.0-11.0-cm) and the locations included the right hepatic artery (n = 5), inferior pancreaticoduodenal artery (n = 1), and gastroduodenal artery (n = 1). All six patients had prior surgical or percutaneous procedures. Median latency period between the original procedure and treatment of pseudoaneurysm was 17 weeks (range one month-16 years). Clinical features ranged from the dramatic presentation of hypotension secondary to intraperitoneal aneurysmal rupture to the subtle presentation of obstructive jaundice secondary to pseudoaneurysm mass effect. The range of patient presentations created diagnostic challenges, proving that accurate diagnosis is made only by early consideration of pseudoaneurysm. Management was ligation of the right hepatic artery (n = 4) and embolization of the pseudoaneurysms (n = 2). Post-treatment sequelae included liver failure requiring liver transplant (n = 1), intrahepatic biloma requiring percutaneous drainage (n = 1) and cholangitis with right hepatic duct strictures requiring right lobectomy and biliary reconstruction (n = 1). These complications followed arterial ligation, with no complications resulting from embolization. All six patients are alive and well after a mean follow-up of 53 months. CONCLUSIONS Our six patients demonstrate the diversity and unpredictability with which a pseudoaneurysm of the extrahepatic arterial vasculature may present in terms of initial symptoms, prior procedures, and the latency period between presentation and prior procedure. Through our experience and an analysis of the literature, we recommend a diagnostic and management approach for these patients.

Abstract
Liver samples of 42 birds belonging to 6 species of Ciconiiformes (grey heron (n = 17), little egret (n = 12), cattle egret (n = 1), glossy ibis (n = 1), little bittern (n = 1), and white stork (n = 10)), collected from two different zones of Spain (Ebro Delta and Madrid) in 1992-1997, were analyzed for organochlorine pesticides and PCBs. SigmaPCBs (sum of concentrations of individual congeners), p,p'-DDE, HCB, gamma-HCH, and heptachlor epoxide were the most prevalent residues detected in all samples (occurrence > 95%). There were no statistically significant differences in organochlorine levels between grey herons and little egrets, while levels of SigmaPCBs, p,p'-DDE, HCB, gamma-HCH, and heptachlor were significantly lower for white storks. These results could be explained by the different habitat of these species, aquatic in the Ebro Delta (grey herons, little egrets) and dry in Madrid (white stork), and their diverse feeding habits.

Abstract
The natural mycobiota occurring in bee pollen is studied in the present report with special attention to analyze the incidence of fungal species that are potential producers of mycotoxins. A total of 90 ready-to-eat bee pollen samples were analyzed. Eighty-seven samples were collected in stores placed in different Spanish areas and three were from Buenos Aires (Argentina). The statistical results (ANOVA) showed that yeasts and Penicillium spp. were the predominant fungi. With regard to the potential mycotoxin producing species, Penicillium verrucosum, Aspergillus niger aggregate, Aspergillus carbonarius, Aspergillus ochraceus, Aspergillus flavus, Aspergillus parasiticus and Alternaria spp. were found. The last genus was isolated very frequently. The potential ability for producing ochratoxin A (OTA) and aflatoxins B(1), B(2), G(1) and G(2) was studied by culturing in vitro the isolates followed by analysis of these mycotoxins in culture extracts by HPLC with fluorescent detection. It was found that 100%, 53.3%, 33.3% and 25% of the isolates of A. carbonarius, A. ochraceus, P. verrucosum and A. niger aggregate, respectively, produced OTA. Moreover, 28.6% of the isolates from the A. flavus plus A. parasiticus group were able to produce aflatoxin B(1). Aflatoxin B(2) was detected in only 10% of the cultures. Aflatoxins G(1) and G(2) were not detected in cultures under the assayed conditions. This is the first report carried out on the natural mycobiota occurring in bee pollen in general and on the toxigenic capability of these isolates in particular.

Abstract
BACKGROUND Despite the risks associated with transfusion, the medical community continues to view blood as a safe and abundant product. In this article, we provide an effective strategy to accomplish orthotopic liver transplantation without transfusion. STUDY DESIGN From June 1999 through July 2004, 27 liver transplantations were performed in Jehovah's Witness patients at the USC-University Hospital (24 adults, 3 children). Nineteen of these were living donor (LD) and eight were deceased donor (DD) liver transplants. Preoperative blood augmentation with erythropoietin and iron was achieved. At induction, all LD and six of eight DD recipients underwent acute normovolemic hemodilution (ANH), and the operation was conducted under conditions of moderate anemia. Cell scavenging techniques were used. Acute normovolemic hemodilution and salvaged blood were returned as needed during bleeding or on completion of transplantation. RESULTS The preoperative liver disease severity score was higher in the deceased donor group. We had 100% graft and patient survivals in the LD group, and 75% in the DD recipients. Two DD recipients died. The remaining are all alive and well, with a mean followup of 965 days (range 266 to 1,979 days) in the LD group and 624 days (range 119 to 1,132 days) in the DD group. CONCLUSIONS Preoperative blood augmentation and acute normovolemic hemodilution provide a safe cushion against operative blood loss. Elective living donor liver transplantation allows full implementation of a transfusion-free strategy in the setting of early hepatic failure, portal hypertension, and anemia. This feat is an important step toward global standardization of transfusion-free surgical practice and an important response to widespread blood shortages and transfusion risks.

Abstract
In the present study, 44 Fusarium spp. isolates (5 Fusarium culmorum, 7 Fusarium graminearum, 1 Fusarium cerealis, 1 Fusarium poae, 26 Fusarium oxysporum, and 4 Gibberella fujikuroi species complex) were characterized morphologically, physiologically and genetically. All except one (Dutch Collection: CBS 620.72) were isolated from different hosts grown in various Spanish localizations. Morphological characterization was made according to macroscopic and microscopic aspects. Physiological characterization was based on their ability to produce zearalenone (ZEA) and type B trichothecenes (deoxynivalenol, nivalenol and 3-acetyldeoxynivalenol). ZEA was determined by liquid chromatography and trichothecenes by gas chromatography. Confirmation was carried out by liquid chromatography-ion trap-mass spectrometry (ZEA) or gas chromatography-mass spectrometry (trichothecenes). Molecular characterization of isolates was performed using an optimized, simple and low-cost method for isolation of DNA from filamentous fungi and polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) of the intergenic spacer region (IGS) of the rRNA gene (rDNA). The results indicate that F. graminearum, F. culmorum and F. cerealis isolates were high ZEA and type B trichothecene producers, the F. poae isolate produced very low level of nivalenol while F. oxysporum and the G. fujikuroi complex isolates did not show this ability. Restriction patterns of the IGS region did not show any relationship with the host, geographic origin of the isolate and mycotoxin-producing capacity. However, the haplotypes obtained with six restriction enzymes (CfoI, AluI, HapII, XhoI, EcoRI and PstI) permitted to discern the six assayed Fusarium species. Therefore, this is a rapid and suitable methodology that allows closely related strains to group and to estimate the genetic relationships between the groups.
