Abstract
Comprehending symbiont abundance among host species is a major ecological endeavour, and the metabolic theory of ecology has been proposed to understand what constrains symbiont populations. We parameterized metabolic theory equations to investigate how bird species' body size and the body size of their feather mites relate to mite abundance according to four potential energy (uropygial gland size) and space constraints (wing area, total length of barbs and number of feather barbs). Predictions were compared with the empirical scaling of feather mite abundance across 106 passerine bird species (26,604 individual birds sampled), using phylogenetic modelling and quantile regression. Feather mite abundance was strongly constrained by host space (number of feather barbs) but not by energy. Moreover, feather mite species' body size was unrelated to the body size of their host species. We discuss the implications of our results for our understanding of the bird-feather mite system and for symbiont abundance in general.

Abstract
INTRODUCTION Temperature and time conditions during storage and distribution of blood components (BC) and their permissible deviations are strictly regulated. The degree of compliance with these requirements in daily practice of transfusion services (TS) is not well known. MATERIALS AND METHODS We conducted a survey among Spanish hospital TS covering different aspects of BC management in their daily activity. RESULTS Eighty-three TS managing 56 % of total transfusions answered the survey. Monitoring of red blood concentrates (RBC) temperature during in-hospital distribution was routinely performed by only 12 % of the TS. The main criterion for BC re-entry into the stock was the total time spent outside controlled temperature. Up to 41 % of the TS apply the "30-minute rule" to distributed RBC, while most services use a 60-minute rule for PC. No adverse events were detected when RBC that had remained longer than 30 or 60 min outside the TS were transfused. Fresh frozen plasma is usually thawed 2 h preissue and stored at 4 °C up to 24 h. DISCUSSION AND CONCLUSIONS In the Spanish context, the 30- and 60-minute rules for re-entry of RBC and PC into the TS stock are loosely followed. Feedback for a large number of TS suggests that the extension of the 30-minute RBC rule to at least 60 min is feasible, if other safety requirements are met. Flexibility with some requirements could help reduce product loss without deleterious effect on BC safety.

Abstract
Viral infections and reactivations are one of the main causes of morbidity and mortality in patients who undergo allogeneic haematopoietic progenitor cell transplantation. Adoptive immunotherapy with virus-specific Tcells (from donor to patient) has shown efficacy in the antiviral treatment of patients who have undergone transplantation and whose immune system has not yet been reconstituted. Currently, and according to the requirements of the corresponding agencies that regulate the production of these advanced personalised therapies, the production and application of these cell products are being optimised in such a way that they comply with good manufacturing practice standards and are safe and effective for treating patients. To facilitate their implementation, we need to understand the foundations of producing and using virus-specific Tcells. This study reviews the evolution of the methodology for producing antiviral Tcells and the studies that support their therapeutic efficacy. The study covers up to the current production platforms, whose commercialisation has begun in Spain. These platforms will help obtain virus-specific Tcells and chimeric antigen receptor Tcells, among others, in a completely automated manner and under good manufacturing practice conditions. The implementation of these new methodologies in the Spanish healthcare system will undoubtedly facilitate patients' access to a new repertoire of advanced therapies.

Abstract
Toll-like receptors (TLRs) are key sensors of mycobacterial infections and play a crucial role in the initiation and coordination of the antimycobacterial innate immune response. T1805G, a functional TLR1 single nucleotide polymorphism (SNP), has been associated with susceptibility to pulmonary tuberculosis (PTB), but contradictory results among different populations have been reported. Our objective was to study this SNP in a genetically homogeneous population to evaluate its role in conferring susceptibility or resistance to PTB. In our population, the 1805G allele and the GG genotype (OR 2.04, 95%CI 1.26-3.31) influence susceptibility to PTB, in contrast with data observed in other populations.

Abstract
In order to describe the influence of Pleistocene glaciations on the genetic structure and demography of a highly mobile, but specialized, passerine, the Savi’s Warbler (Locustella luscinioides), mitochondrial DNA sequences (ND2) and microsatellites were analysed in c.330 individuals of 17 breeding and two wintering populations. Phylogenetic, population genetics and coalescent methods were used to describe the genetic structure, determine the timing of the major splits and model the demography of populations. Savi’s Warblers split from its sister species c.8 million years ago and have two major haplotype groups that diverged in the early/middle Pleistocene. One of these clades originated in the Balkans and is currently widespread, showing strong evidence for population expansion; whereas the other is restricted to Iberia and remained stable. Microsatellites agreed with a genetic break around the Pyrenees, but showed considerable introgression and a weaker genetic structure. Both genetic markers showed an isolation-by-distance pattern associated with the population expansion of the eastern clade. Breeding populations seem to be segregated at the wintering sites, but results on migratory connectivity are preliminary. Savi’s Warbler is the only known migratory bird species in which Iberian birds did not expand beyond the Pyrenees after the last glaciation. Despite the long period of independent evolution of western and eastern populations, complete introgression occurred when these groups met in Iberia. Mitochondrial sequences indicated the existence of refugia-within-refugia in the Iberian Peninsula during the last glacial period, which is surprising given the high dispersal capacity of this species. Plumage differences of eastern subspecies seemed to have evolved recently through natural selection, in agreement with the glacial expansion hypothesis. This study supports the great importance of the Iberian Peninsula and its role for the conservation of genetic variation.

Abstract
BACKGROUND AND OBJECTIVES In contrast with hematologic malignancies in which the value of immunophenotypic studies is well established, information on the immunophenotypic characteristics of myelodysplastic syndromes (MDS) is scanty. The main goal of the present study was to explore the immunophenotypic differences between patients with MDS and normal individuals, including changes in distribution of cell lineages as well as phenotypic aberrations and blockades in cell maturation pathways. DESIGN AND METHODS In MDS the proportion of bone marrow CD34+ cells was higher than in normal patients but the most immature progenitors (CD34+CD38-) were less represented. By contrast the proportion of myelomonocytic CD34+ cells was greater than in normal individuals, translating into an increased myeloid/non-myeloid CD34+ hematopoietic progenitor cell ratio. RESULTS This suggests that in MDS, the majority of CD34+ cells are already committed to the myeloid lineage. Upon analyzing the granulo-monocytic differentiation pathway, MDS patients showed an increased proportion of monocytic cells with a decreased percentage of cells of neutrophil lineage, leading to a lower neutrophil/monocytic cell ratio. Maturational arrests in the monocytic but not in the neutrophil differentiation pathway were observed. In refractory anemia with excess blasts in transformation (RAEB-t) such blockades mainly occurred during the earliest stages of differentiation but in the other MDS subtypes they occurred in later stages. INTERPRETATION AND CONCLUSIONS Phenotypic aberrations occurred in 90% of patients and a high proportion of cases showed >=2 aberrations. In summary, our results show that, in addition to an abnormal distribution of the bone marrow cell compartment, MDS patients frequently show aberrant phenotypes and maturational arrests. Some of these features may help in cases in which the diagnosis of MDS is questionable.

Abstract
BACKGROUND Almost all automated hematology cell analyzers use methods based on either the impedance (PLTi) or the optical (PLTo) properties of the cells for performing platelet counts. To improve the accuracy of platelet counts in peripheral blood (PB), the use of CD61 (GPIIIa) MoAbs (ImmunoPLT method) has recently been introduced in an automated hematology blood-analyzer system (Cell-Dyn 4000, Abbott Diagnostics). STUDY DESIGN AND METHODS A comparative evaluation was made of the accuracy and precision of the three methods currently available in the Cell-Dyn 4000 automated hematology cell analyzer for counting the number of platelets per microliter of PB in a total of 47 patients with chemotherapy-induced thrombocytopenia. A flow cytometric PB platelet count was also performed in parallel and used as an external reference. RESULTS PB platelet counts showed a good correlation among the PLTo, CD61-ImmunoPLT, and flow cytometric methods. In contrast, the PLTi procedure usually provided an overestimation of the number of platelets per microliter. Although a good correlation was observed between the flow cytometric reference method and both the ImmunoPLT and PLTo methods, the highest degree of agreement was found for the ImmunoPLT techniques (94% vs. 67%). A comparative analysis of the PLTo and CD61-ImmunoPLT methods with regard to their value for predicting platelet transfusion needs on the basis of specific flow cytometric platelet count thresholds showed a good correlation when the cutoff level of 10,000 platelets per microL was used. In contrast, at the threshold of 20,000 platelets per microL, slight differences were observed between the PLTo and CD61-ImmunoPLT procedures for predicting transfusion needs. CONCLUSION Such results indicate that, if the CD61-ImmunoPLT method is used in the platelet transfusion decision-making process, unnecessary platelet transfusions could be avoided in up to 17.5 percent of persons with a PLTo count of <20,000 platelets per microL.

We report the case of an 18-year-old patient who received an allogeneic bone marrow transplant from an HLA-identical unrelated donor for a Ph+ acute lymphoblastic leukemia, in his third complete remission. Cyclophosphamide and busulfan were used as conditioning treatment. Acute graft-versus-host disease developed on day +9, and the response to adequate treatment (steroids) was favourable. On day +45 the patient developed an acute severe haemorhragic cystitis, and BK polyomavirus was demonstrated in urine samples using electron microscopy and polymerase chain reaction. Urinary symptoms did not improve in spite of palliative treatment, but a response was evident after 2 weeks of cidofovir treatment.

Abstract
We report on a case of pyridoxine refractory hereditary sideroblastic anaemia (HSA) in a 19-year-old man who underwent peripheral blood stem cell transplantation (PBSCT) from his HLA-identical brother. By using short tandem repeat polymorphism, 100% donor cells were observed in peripheral blood on day +21; bone marrow showed mixed chimaerism from day +21 to day +221, when 100% cells of donor origin were observed. The patient developed extensive chronic graft-versus-host disease with favourable response to treatment. When the haemoglobin range was normal, a programme of phlebotomies reduced serum ferritin levels. Three years after transplantation, the patient has an ECOG rating of 0, with completely normal haemoglobin values (15 g/dl). To our knowledge, this is the first PBSCT reported in a case of hereditary sideroblastic anaemia.

Abstract
BACKGROUND Patients on cardiopulmonary bypass (CPB) have an increased susceptibility to postoperative bleeding. Previous reports using desmopressin acetate (DDAVP) for the prevention of postoperative bleeding have given contradictory results, whereas the protease inhibitor aprotinin has been shown to reduce blood loss after this type of surgery. This randomized study was performed to assess the efficacy of DDAVP versus aprotinin in the prevention of bleeding after CPB. METHODS AND RESULTS One hundred nine of 122 eligible patients were randomized to four different groups: Group A (n = 28) received aprotinin starting with a bolus of 2 x 10(6) KIU followed by a continuous infusion of 0.5 x 10(6) KIU/h until the end of surgery; group B (n = 25) received of DDAVP 0.3 micrograms/kg i.v. on completion of CPB; group C (n = 28) received two doses of DDAVP, the first as in group B and an additional dose 6 hours after surgery; group D (n = 28) received no treatment. There was a marked reduction of postoperative blood loss either at 12 hours (P < .01) or 72 hours (P < .02) in the aprotinin group compared with all other groups, whereas no significant effect was observed in either of the two DDAVP regimens. A significant reduction in the amount of blood used was observed only in the aprotinin group (P < .01). Of the plasma fibrinolytic components assayed, there was a significant reduction of the fibrin degradation product generation in the aprotinin group (P < .001), whereas a significant systemic hyperfibrinolysis was observed in both DDAVP-treated groups and the control group. No side effects related to the study drugs were observed in any patient. CONCLUSIONS Aprotinin inhibited fibrinolysis; this correlated with a significant reduction of postoperative blood loss and need for blood replacement after CPB. Neither one nor two doses of DDAVP had a beneficial effect. Aprotinin offers a better alternative than DDAVP in the prevention of bleeding after CPB.

Abstract
OBJECTIVES To compare two techniques for total intravenous anesthesia (TIVA): midazolam-alfentanil-flumazenil and propofol-alfentanil, contrasting them with combined anesthesia (thiopental-isoflurane-alfentanil) and assessing the efficacy of flumazenil in continuous perfusion for preventing resedation in TIVA with midazolam. PATIENTS AND METHODS The efficacy and clinical tolerance of the 3 anesthetic techniques with propofol, midazolam or isoflurane were studied in 63 patients undergoing elective breast, lumbar or gynecological surgery. Anesthetic induction was achieved with midazolam 0.3 mg/kg-1 (group M), propofol 2.5 mg/kg-1 (group P) or thiopental 3 mg/kg-1 (group I); all patients also received 50 micrograms/kg-1 alfentanil and vecuronium bromide 0.12 mg/kg-1/h-1. Maintenance was achieved with midazolam in perfusion at 0.12 mg/kg-1/h-1 (group M); propofol in perfusion at 7 mg/kg-1/h-1 and a pre-incision dose of 1.5 mg/kg-1 (group P); and isoflurane at 1.15% (group I). The 3 groups also received one pre-incision dose of alfentanil 25 micrograms/kg-1 and post-incision perfusion at 60 micrograms/kg-1/h-1. The infusion of alfentanil was changed by amounts of 20 micrograms/kg-1/h-1 in accordance with the patient's response to surgery. After surgery patients in group M received flumazenil 0.5 mg i.v. over 30 sec and a perfusion of flumazenil 0.5 mg over 60 min. Parameters indicating efficacy were: 1) total dose and timing of alfentanil; 2) number of instances of inadequate anesthesia; 3) peri-operative amnesia; 4) times of awakening and extubation after surgery, and 5) the number of patients in each group who required naloxone. Parameters indicating tolerance were: 1) hemodynamic variables; 2) the number of postoperative desaturations; 3) level of sedation, comprehension and motor coordination and orientation; 4) the "G/g detection" test and the memory recall test; 5) adverse side effects; 6) need for postoperative analgesia, and 7) evaluation of the anesthetic technique. RESULTS The 3 techniques afforded effective control of hemodynamic response to intubation and surgical incision. Anesthetic maintenance was easy and safe with isoflurane and propofol. Higher doses of alfentanil, however, were needed with midazolam and we found a higher incidence of signs of superficial anesthesia. Reversion of midazolam with flumazenil 0.5 mg i.v. produced earlier awakening, although this was followed later by relapse into hypno-sedation that could not be prevented with a perfusion of flumazenil. Although recovery from anesthesia was slower with propofol than with isoflurane, we observed no differences in level of sedation, motor coordination and postoperative comprehension. Maintenance with isoflurane produced a higher incidence of adverse side effects such as tremors and nausea after surgery. CONCLUSIONS None of the TIVA techniques proved superior in all the parameters studied during anesthetic maintenance when compared with balanced isoflurane-alfentanil, although the propofol-alfentanil combination was found to be superior to that of midazolam-alfentanil. After anesthesia, however, recovery was better with the association of propofol-alfentanil and adverse side effects were fewer. Flumazenil at the doses used was ineffective for preventing resedation due to midazolam.

Abstract
BACKGROUND AIMS The effects of two anesthetic agents, alfentanil and isoflurane, on the macrophage-monocytic system and the relation with the adrenocortical-hypophyseal axis were analyzed. MATERIAL AND METHODS Thirty ASA I-II patients submitted to elective surgery were distributed into two groups: group I, analgesic anesthesia with alfentanil 100 micrograms/kg, a perfusion of 2-3 micrograms/kg/min and naloxone 0.2-0.4 mg upon termination of surgery; group II, inhalation anesthesia with isoflurane at 2-2.5% and O2/air = 1/1. HLA-DR membrane receptors and vimentin threads of the cytoskeleton were determined in basal conditions, at one hour and two hours of induction and upon termination of surgery by means of indirect immunofluorescence with the use of monoclonal antibodies. Phagocytosis of latex particles was also measured and ACTH and cortisol levels were obtained by radioimmunoassay. RESULTS In group I (alfentanil) a decrease (p < 0.01) of all the monocyte parameters analyzed, which was more significant than that observed in group II (isoflurane), was observed. In group II only the expression of HLA-DR and the index of phagocytosis (p < 0.05) were statistically significant. Following the administration of naloxone a reversion of these parameters was observed. The maximum immune depression corresponded with the lowest values of ACTH and cortisol (group I) with surgical stress being discarded as the cause of this immunodepression. CONCLUSIONS Alfentanil produces a monocytic depression which reverses following the administration of naloxone, thus discarding surgical stress as the cause of this immunodepression suggesting a mechanism mediated by opiate receptors. With regards to isoflurane, the functions of the mononuclear-phagocytic system were hardly altered in the patient studied.

Abstract
We evaluated in human monocytes the effect of high doses of alfentanyl on the expression of vimentin filaments, the phagocytic activity and the membrane display of HLA-DR molecules in the subjects undergoing surgery. The study was performed on 30 patients, ASAI-II. The patients received 100 mcg/kg i.v. of Alfentanil and the maintenance of anaesthesia was made with Alfentanil (2-3 mcg/kg/min.). The patients were randomized in two groups. The patients were ventilated with N2O:O2 (1:1) (Group I) or air: O2 (1:1) (Group II). After surgery, all patients of the Group II received Naloxone (0.2-0.4 mg). Central venous blood samples were obtained before induction, one and two hours after induction of anaesthesia and at the end of surgery. Separation of monocytes was performed according to Boyum technique. CD35 and HLA-DR molecules and vimentin filaments were studied by indirect immunofluorescence method using monoclonal antibodies. Percentage of positive cells were read with a cytofluorometer. The phagocytic function of monocytes was determined by ingestion of latex particles. Cortisol and ACTH plasma levels were determined by RIA. High doses of Alfentanyl depress phagocytic function and membrane display of CD35 and HLA-DR molecules in monocyte and induce marked changes in the organization of vimentin filaments in these cells in patients undergoing surgery. This monocytic depression was more marked in the patients ventilated with N2O. In our results there was uninhibition of ACTH and cortisol plasma levels responses to surgical stress by Alfentanil administration. Since the effects of Alfentanil were reversed by Naloxone, an opioid receptor mechanism seems to mediate these events.

Abstract
Midazolam (MDZ) (8-chloro-6(2-fluoropheny 1)-1-methyl-4H-imidazol-[1,5a] [1,4]benzodiazepine) is an "annelated" benzodiazepine (BZDs) synthetized in 1976, characterized differently with the "classical" BZDs by a five-membered heterocycle fused on position 1,2 of the diazepine nucleus. This fused imidazol ring modifies the properties inherent in the "classical" BZDs in at the least three aspects: solubility, metabolisation and the stability in aqueous solution. MDZ, having similar properties with the "classical" benzodiazepines, has better local tolerance, faster onset of action, greater plasmatic clearance, shorter half-life elimination (1.7-2.4 hr) with no active metabolites. With a bioavailability of 92% (IV), 82-91% (IM) and 50-52% "per os", the CNS effects of MDZ are similar in all three ways. In anesthesiology we can administer MDZ as an anesthetic premedication ("per os", IM or IV), anesthetic induction and maintenance and IV sedation in locorregional anesthetic procedures or diagnostic and therapeutic explorations. MDZ has a great safety margin, moderate respiratory and cardiovascular effects and lacks of teratogenic or embryotoxic effects.

Abstract
It is theorized that intermediate filaments are important in the modulation of membrane activity and cell motility; however, their functions are unknown. The assembly and organization of these filaments are under hormonal regulation. We investigated in human monocytes the in vitro effects of Met-enkephalin, Leu-enkephalin, and beta-endorphin on the expression of immunoreactive cytoskeletal vimentin filaments. We simultaneously examined their effect on the phagocytosis of Candida albicans and on the membrane display of surface molecules. The three opioid peptides markedly reduced the expression of vimentin filaments, the phagocytic activity, and the display of HLA-DR molecules at concentrations of 10(-6), 10(-8), and 10(-10) M. On the other hand, the intravenous administration of fentanyl, a synthetic opiate agonist, to patients undergoing surgery induced similar changes in monocytes. In other experiments, 10(-8) M beta-endorphin also decreased the expression of CR3 but did not influence the display of CD13, a surface protein of unknown function. Expression of vimentin filaments correlated directly with the display of HLA-DR antigens and CR3 and with the phagocytic activity. The results of this paper indicate that opiates and opioids, neuropeptides known to be released during stress, can directly depress several monocyte functions. Furthermore, from these data it may be speculated that intermediate filaments may regulate the membrane expression of some surface molecules and the phagocytic process.

Abstract
The purpose of the present study was to assess the repercussion of morphine injected in the intrathecal space on postoperative neuroendocrine response and the correlation with pain relief in the postop period. We studied 50 healthy patients (ASA I-II) submitted to orthopaedic surgery under general anaesthesia (N = 25) or spinal anaesthesia (N = 25). In the group under general anaesthesia we observed a hypersecretion of ADH, ACTH, cortisol and aldosterone during and after surgery. In the group un spinal anaesthesia, it was evident, on the contrary, a blockade of the neuroendocrine response during surgery, as well as an attenuation during postoperative period. Intraoperative and postoperative bleeding with spinal anaesthesia was significantly lower (p less than 0.01; p less than 0.05 respectively) than with general anaesthesia. Postoperative analgesia was excellent in group with spinal anaesthesia; the average duration of analgesia was 16.3 hours. We conclude that small intrathecal doses of morphine have beneficial effects and may be used usefulness in orthopaedic surgery.

Abstract
The effects of labetalol on the secretion of prostacyclin and plasma-renin activity (PRA) were evaluated, relative to a control group in 24 patients undergoing hip osteotomy. They were randomly assigned to two groups (G-I and G-II) with 12 patients each. Patients allocated to both groups received standard anaesthesia (thiopentone, pancuronium, fentanyl and nitrous oxide). Patients belonging to Group II were given labetalol at a dose of 0.8 mg kg-1. The stable metabolite of PGI2, 6-keto-PGF1 alpha was quantified from urine samples by radioimmunoassay (RIA). Cortisol, PRA and aldosterone were determined from blood samples. A significant increase in 6-keto-PGF1 alpha elimination was observed in G-I. Labetalol administration partially but significantly inhibited this increase. We believe that prostacyclin is involved not through the beta 1 but through the alpha 1 receptors in the secretion of renin.

Abstract
The effect of standard anaesthesia (G-I) and epidural analgesia (G-II) on urinary synthesis of PGE2 was compared in two groups of 12 patients each undergoing orthopaedic surgery. This study demonstrates a significant elevation of renal PGE2 in patients undergoing standard anaesthesia during surgery. In marked contrast, with epidural analgesia, the inhibition of renal secretion of PGE2 is apparent. These findings strongly suggest the important role of the sympathetic nervous system in the synthesis of PGE2.

Abstract
The endocrine, humoral and hemodynamic factors that affect renin secretion are studied during open-heart surgery in a group of 40 patients, 20 with mitral and 20 with aortic valve disease. During the incission period, the PRA (plasma renin activity) increases due to a sympatoadrenergic hyperactivity. These increase is noted also during bypass, and is closely related with the hypotension that extracorporeal circulation produces. It is also discussed the influence of the exclusion of pulmonary circulation, that decreases conversion of angiotensin I to II and catabolism of norepinephrine.

Abstract
In 91 patients who had undergone surgery under C.E.C. the influence of the analgesia on adrenal cortex system was studied. With the exception of the analgesic used, the anaesthesia was performed following the same guidelines in all of the operations. Concentrations of cortisol in plasma were maximum with Pentazocina, the weakest analgesic used by us, and minimum with Fentanest. In view of these results, we can affirm that, in the absence of alterations haemodynamic, metabolic and neurological, concentrations of cortisol in plasma are a true reflexion of the amount of analgesic protection that different drugs offer against noxins stimuli triggered by the surgical act. These findings guarantee the intimate relationship that exists between the nervous system and the endocrine system and they are further confirmed by results obtained with a recently acquired analgesic Fentathienil, which is more potent than Fentanyl.
