Abstract
PURPOSE To study vision related quality of life (VRQoL) before and after a massive cataract campaign in West Africa and the relationship with visual indicators. METHODS All the patients who received cataract surgery in Burkina Faso during a blindness prevention campaign were examined. VRQoL was assessed using a modified version of the WHO/PBD VF20. The questionnaire was changed to reflect the socioeconomic and local culture. Patients were interviewed by local interviewers before and three months after surgery. A quality of life related to vision index (QoL-RVI) was calculated. RESULTS A total of 305 patients underwent cataract extraction in at least one eye, of these, a total of 196 (64%) completed the study. Mean age was 61.97 ± 14.39 years. The majority of eyes had poor visual acuity (VA<20/200, log MAR: 1.0) preoperatively (88.70%) with a mean VA of logMAR 2.17 ± 0.70 (20/2000) which improved to 0.86 ± 0.64 LogMAR (20/150) 3 months after cataract surgery. QoL-RVI improved postoperatively in 90.2% of patients, did not change in 3.1% and was worse in 6.7%. Statistically significant differences were detected (Wilcoxon test p <0.05) for all items tested before and after surgeries. Correlations for the patients after operations showed that there was a statistically significant relation between a global estimated QoL-RVI and the VA previous to the surgery (-0.196 p=0.014), regarding the same index and the VA after the procedures (-0,35 p=0,00018). CONCLUSION Cataract surgery increases the quality of life of patients living in a developing country such as Burkina Faso and the improvement correlates with the recovery of the visual acuity.

Abstract
Neuroleptic malignant syndrome is a rare medical emergency associated with the use of antipsychotics and other antidopaminergic drugs. There is no specific test, and diagnosis is based on high clinical suspicion and good differential diagnosis. A clinical picture consistent with hyperthermia, muscle rigidity, altered level of consciousness, together with signs of rhabdomyolysis in analytical studies and a history of taking neuroleptic drugs are the key elements in the detection of this entity. Due to its low incidence and potential mortality, it is essential to publish case reports of neuroleptic malignant syndrome in order to raise awareness of this entity and facilitate diagnostic suspicion when encountering a patient with compatible symptoms. The following is the case of a 79 year old patient with chronic alcohol consumption as the only history of interest, who was given a single dose of haloperidol after an episode of delirium in the postoperative period of conventional trauma surgery. She subsequently developed a picture of progressive deterioration of the level of consciousness, diaphoresis, generalized muscle rigidity, hyperthermia, together with severe metabolic acidosis, hyperlacticaemia, rhabdomyolysis, hypertransaminasemia and hypocalcemia. After ruling out other entities compatible with the clinical picture, neuroleptic malignant syndrome was given as the main diagnostic hypothesis. Diagnosis was confirmed after clinical and analytical improvement following treatment with dantrolene. The patient was discharged from hospital with no sequelae a few days after onset of the condition.

Abstract
Many classes of compounds are known or suspected to disrupt the endocrine system of vertebrate and invertebrate organisms. This review of the sources and fate of selected endocrine disrupting chemicals (EDCs) in the environment includes classes of compounds that are "legacy" contaminants, as well as contaminants of emerging concern. EDCs included for discussion are organochlorine compounds, halogenated aromatic hydrocarbons, brominated flame retardants, per- and polyfluoroalkyl substances, alkylphenols, phthalates, bisphenol A and analogues, pharmaceuticals, drugs of abuse and steroid hormones, personal care products, and organotins. An exhaustive survey of the fate of these contaminants in all environmental media (e.g., air, water, soil, biota, foods and beverages) is beyond the scope of this review, so the priority is to highlight the fate of EDCs in environmental media for which there is a clear link between exposure and endocrine effects in humans or in biota from other taxa. Where appropriate, linkages are also made between the fate of EDCs and regulatory limits such as environmental quality guidelines for water and sediments and total daily intake values for humans.

Abstract
Endocrine disrupting chemicals (EDCs) are heterogenous in structure, chemical and physical properties, and their capacity to partition into various environmental matrixes. In many cases, these chemicals can disrupt the endocrine systems of vertebrate and invertebrate organisms when present at very low concentrations. Therefore, sensitive and varied analytical methods are required to detect these compounds in the environment. This review summarizes the analytical methods and instruments that are most used to monitor for EDCs in selected environmental matrixes. Only those matrixes for which there is a clear link between exposures and endocrine effects are included in this review. Also discussed are emerging methods for sample preparation and advanced analytical instruments that provide greater selectivity and sensitivity.

Abstract
Background The clinical course of COVID-19 critically ill patients, during their admission in the intensive care unit (UCI), including medical and infectious complications and support therapies, as well as their association with in-ICU mortality has not been fully reported. Objective This study aimed to describe clinical characteristics and clinical course of ICU COVID-19 patients, and to determine risk factors for ICU mortality of COVID-19 patients. Methods Prospective, multicentre, cohort study that enrolled critically ill COVID-19 patients admitted into 30 ICUs from Spain and Andorra. Consecutive patients from March 12th to May 26th, 2020 were enrolled if they had died or were discharged from ICU during the study period. Demographics, symptoms, vital signs, laboratory markers, supportive therapies, pharmacological treatments, medical and infectious complications were reported and compared between deceased and discharged patients. Results A total of 663 patients were included. Overall ICU mortality was 31% (203 patients). At ICU admission non-survivors were more hypoxemic [SpO2 with non-rebreather mask, 90 (IQR 83–93) vs 91 (IQR 87–94); p < 0.001] and with higher sequential organ failure assessment score [SOFA, 7 (IQR 5–9) vs 4 (IQR 3–7); p < 0.001]. Complications were more frequent in non-survivors: acute respiratory distress syndrome (ARDS) (95% vs 89%; p = 0.009), acute kidney injury (AKI) (58% vs 24%; p < 10−16), shock (42% vs 14%; p < 10−13), and arrhythmias (24% vs 11%; p < 10−4). Respiratory super-infection, bloodstream infection and septic shock were higher in non-survivors (33% vs 25%; p = 0.03, 33% vs 23%; p = 0.01 and 15% vs 3%, p = 10−7), respectively. The multivariable regression model showed that age was associated with mortality, with every year increasing risk-of-death by 1% (95%CI: 1–10, p = 0.014). Each 5-point increase in APACHE II independently predicted mortality [OR: 1.508 (1.081, 2.104), p = 0.015]. Patients with AKI [OR: 2.468 (1.628, 3.741), p < 10−4)], cardiac arrest [OR: 11.099 (3.389, 36.353), p = 0.0001], and septic shock [OR: 3.224 (1.486, 6.994), p = 0.002] had an increased risk-of-death. Conclusions Older COVID-19 patients with higher APACHE II scores on admission, those who developed AKI grades II or III and/or septic shock during ICU stay had an increased risk-of-death. ICU mortality was 31%.

Abstract
Antecedentes No se ha reportado plenamente la evolución clínica de los pacientes críticos de COVID-19 durante su ingreso en la unidad de cuidados intensivos (UCI), incluyendo las complicaciones médicas e infecciosas y terapias de soporte, así como su asociación con la mortalidad en UCI. Objetivo El objetivo de este estudio es describir las características clínicas y la evolución de los pacientes ingresados en UCI por COVID-19 y determinar los factores de riesgo de la mortalidad en UCI de dichos pacientes. Métodos Estudio prospectivo, multicéntrico y de cohorte, que incluyó a los pacientes críticos de COVID-19 ingresados en 30 UCI de España y Andorra. Se incluyó a los pacientes consecutivos del 12 de marzo al 26 de mayo del 2020 si habían fallecido o habían recibido el alta de la UCI durante el periodo de estudio. Se reportaron los datos demográficos, los síntomas, los signos vitales, los marcadores de laboratorio, las terapias de soporte, terapias farmacológicas y las complicaciones médicas e infecciosas, realizándose una comparación entre los pacientes fallecidos y los pacientes dados de alta. Resultados Se incluyó a un total de 663 pacientes. La mortalidad general en UCI fue del 31% (203 pacientes). Al ingreso en UCI los no supervivientes eran más hipoxémicos (SpO2 con mascarilla de no reinhalación, de 90 [RIC 83-93] vs. 91 [RIC 87-94]; p < 0,001] y con mayor puntuación en la escala SOFA-Evaluación de daño orgánico secuencial (SOFA, 7 [RIC 5-9] vs. 4 [RIC 3-7]; p <0,001]). Las complicaciones fueron más frecuentes en los no supervivientes: síndrome de distrés respiratorio agudo (SDRA) (95% vs. 89%; p = 0,009), insuficiencia renal aguda (IRA) (58% vs. 24%; p < 10–6), shock (42% vs. 14%; p < 10–13) y arritmias (24% vs. 11%; p < 10–4). Las superinfecciones respiratorias, infecciones del torrente sanguíneo y los shock sépticos fueron más frecuentes en los no supervivientes (33% vs. 25%; p = 0,03, 33% vs. 23%; p = 0,01 y 15% vs. 3%, p = 10–7, respectivamente). El modelo de regresión multivariable reflejó que la edad estaba asociada a la mortalidad y que cada año incrementaba el riesgo de muerte en un 1% (IC del 95%: 1-10, p = 0,014). Cada incremento de 5 puntos en la escala APACHE II predijo de manera independiente la mortalidad (odds ratio [OR]: 1,508 [1,081, 2,104], p = 0,015). Los pacientes con IRA (OR: 2,468 [1,628, 3,741], p < 10–4)], paro cardiaco (OR: 11,099 [3,389, 36,353], p = 0,0001] y shock séptico [OR: 3,224 [1,486, 6,994], p= 0,002) tuvieron un riesgo de muerte incrementado. Conclusiones Los pacientes mayores de COVID-19 con puntuaciones APACHE II más altas al ingreso, que desarrollaron IRA en grados ii o iii o shock séptico durante la estancia en UCI tuvieron un riesgo de muerte incrementado. La mortalidad en UCI fue del 31%.

Abstract
BACKGROUND Patients with chronic deltoid ligament insufficiency (CDLI) present a challenging situation. Although numerous procedures have been described, optimal treatment is still a matter of debate. While the treatment armamentarium ranges from simple ligament repair to complex reconstructions with or without realignment osteotomies, direct repair augmented with an Internal Brace™ device appears to be an attractive intermediate option. We investigated functional outcomes and complications in patients with CDLI operated on using Internal Brace™ augmentation. METHODS A prospective study was conducted. Patients were included if they presented medial ankle pain and/or giving way, exhibited asymmetric flexible hindfoot valgus, failed conservative treatment, and had a positive MRI evaluated by an independent radiologist. Patients with stage IV flatfoot deformity, neuropathy and/or inflammatory arthritis were excluded. CDLI was confirmed intraoperatively with the arthroscopic drive-through sign. Patients were evaluated preoperatively and postoperatively using FAAM, SF-36 and grade of satisfaction. Paired t-tests were used to assess FAAM and SF-36 scores variation. RESULTS Thirteen patients met inclusion criteria. No patient was lost to follow-up, with a mean follow-up time of 13.5 months (range 6-21). Preoperative FAAM and SF-36 scores improved from 58.7 to 75.3 and from 60.2 to 84.4 postoperatively, respectively (p<.01). Two implant failures were observed, with no apparent compromise of construct stability. No patient was re-operated. CONCLUSIONS Our results suggest that deltoid ligament repair with Internal Brace™ augmentation in patients with CDLI is a reliable option with good functional outcomes and high satisfaction grade in short term follow-up. LEVEL OF EVIDENCE Level IV.

Abstract
Background Personalised medicine is nowadays a major objective in oncology. Molecular characterization of tumours through NGS offers the possibility to find possible therapeutic targets in a time- and cost-effective way. However, the low quality and complexity of FFPE DNA samples bring a series of disadvantages for massive parallel sequencing techniques compared to high-quality DNA samples (from blood cells, cell cultures, etc.). Results We performed several experiments to understand the behaviour of FFPE DNA samples during the construction of SureSelectQXT libraries. First, we designed a quality checkpoint for FFPE DNA samples based on the quantification of their amplification capability (qcPCR). We observed that FFPE DNA samples can be classified according to DIN value and qcPCR concentration into unusable, or low-quality (LQ) and good-quality (GQ) DNA. For GQ samples, we increased the amount of input DNA to 150 ng and the digestion time to 30 min, whereas for LQ samples, we used 50 ng of DNA as input but we decreased the digestion time to 1 min. In all cases, we increased the cycles of the pre-hyb PCR to 10 but decreased the cycles of the post-hyb PCR to 8. In addition, we confirmed that using half of the volume of reagents can be beneficial. Finally, in order to obtain better results, we designed a decision flow-chart to achieve a seeding concentration of 12–14 pM for MiSeq Reagent Kit v2. Conclusions Our experiments allowed us to unveil the behaviour of low-quality FFPE DNA samples during the construction of SureSelectQXT libraries. Sequencing results showed that, using our modified SureSelectQXT protocol, the final percentage of usable reads for low-quality samples was increased more than three times allowing to reach median depth/million reads values of 76.35. This value is equivalent to ~ 0.9 and ~ 0.7 of the values obtained for good-quality FFPE and high-quality DNA respectively.

Abstract
Undifferentiated and dedifferentiated endometrial carcinomas are rare and highly aggressive subtypes of uterine cancer, not well characterized at a molecular level. To investigate whether dedifferentiated carcinomas carry molecular genetic alterations similar to those of pure undifferentiated carcinomas, and to gain insight into the pathogenesis of these tumors, we selected a cohort of 18 undifferentiated endometrial carcinomas, 8 of them with a well-differentiated endometrioid carcinoma component (dedifferentiated endometrioid carcinomas), and studied them by immunohistochemistry and massive parallel and Sanger sequencing. Whole-exome sequencing of the endometrioid and undifferentiated components, as well as normal myometrium, was also carried out in one case. According to The Cancer Genome Atlas classification, we distributed 95% of the undifferentiated carcinomas in this series as follows: (a) hypermutated tumors with loss of any mismatch repair protein expression and microsatellite instability (eight cases, 45%); (b) ultramutated carcinomas carrying mutations in the exonuclease domain of POLE (two cases, 11%); (c) high copy number alterations (copy-number high) tumors group exhibiting only TP53 mutations and high number of alterations detected by FISH (two cases, 11%); and (d) low copy number alterations (copy-number low) tumors with molecular alterations typical of endometrioid endometrial carcinomas (five cases, 28%). Two of the latter cases, however, also had TP53 mutations and higher number of alterations detected by FISH and could have progressed to a copy-number high phenotype. Most dedifferentiated carcinomas belonged to the hypermutated group, whereas pure undifferentiated carcinomas shared molecular genetic alterations with copy-number low or copy-number high tumors. These results indicate that undifferentiated and dedifferentiated endometrial carcinomas are molecularly heterogeneous tumors, which may have prognostic value.

Abstract
INTRODUCTION Ancillary hospital personnel represent an important body of opinion because as they work in a hospital their opinion has more credibility for the general public as a result of their activity in hospitals. However, in most cases they do not have any health care training which means that their attitude could be based on a lack of knowledge or unfounded fears. OBJECTIVE To analyze the attitude toward living kidney donation (LKD) among ancillary personnel in Spanish and Latin-American hospitals and to analyze the variables that might influence such attitude. PATIENTS AND METHOD from «International Collaborative Donor Project» a random sample was taken among ancillary personnel in Spain, Mexico and Cuba hospitals. Attitude towards LKD was evaluated using a validated, anonymously filled and self-administered survey. RESULTS 951 professionals were surveyed (Spain: 277, Mexico: 632, Cuba: 42). 89% (n=850) are in favor of related kidney donation, lowering to 31% (n=289) in non-related donation. Of the rest, 8% (n=78) are not in favor and the 3% (n=23) are unsure. By country, Cubans (98%) and Mexicans (91%) are more in favour than Spanish (84%) (P=.001). The following variables are related to favourable attitude towards LKD: female sex (P=.017), university degree (P=.010), work in health services (P=.035), labour stability (P=.016), personal experience in donation and transplantation (P=.001), positive attitude toward cadaveric donation (P<.001), belief that he or she might need a transplant in the future (P<.001), positive attitude towards living liver donation (P<.001), a willingness to receive a donated living liver if needed (P<.001), having discussed the subject of organ donation and transplantation within the family (P<.001), partner's positive attitude towards the subject (P<.001), participation in voluntary type pro-social activities (P=.002) and not being concerned about possible mutilation after donation (P<.001) CONCLUSIONS: The attitude toward living related kidney donation is favourable among ancillary personnel in Spanish and Latin-Americans hospitals. Because living donation is a better source of organs than cadaveric ones, this favourable predisposition can be used as promoting agent of living donation in order to develop it in Spanish-speaking countries.

Abstract
BACKGROUND Healthcare assistants are an important group of workers who can influence public opinion. Their attitudes toward organ donation may influence public awareness of healthcare matters; negative attitudes toward donation and transplantation could have a negative impact on public attitudes. Our objective was analyze the attitudes of healthcare assistants, in Spanish and Mexican healthcare centers toward organ donation and determine factors affecting them using a multivariate analysis. MATERIAL AND METHODS As part of the "International Collaborative Donor Project," 32 primary care centers and 4 hospitals were selected in Spain and 5 hospitals in Mexico. A randomized sample of healthcare assistants was stratified according to healthcare services. Attitudes were evaluated using a validated questionnaire of the psychosocial aspects of donation, which was self-completed anonymously by the respondent. Statistical analysis used the chi-square test, Student t test, and logistic regression analysis. RESULTS Of 532 respondents, 66% in favored donation and 34% were against it or undecided. Upon multivariate analysis, the following variables had the most weight: 1) country of origin (Mexicans were more in favor than Spanish; odds ratio [OR]) = 1.964; P = .014); 2) a partner with a favorable attitude (OR = 2.597; P = .013); 3) not being concerned about possible bodily mutilation after donation (OR = 2.631; P = .006); 4) preference for options apart from burial for handling the body after death (OR = 4.694; P < .001) and 5) accepting an autopsy if one was needed (OR = 3.584; P < .001). CONCLUSIONS The attitudes of healthcare assistants toward organ donation varied considerably according to the respondent's country of origin. The psycho-social profile of a person with a positive attitude to donation was similar to that described within the general public.

Abstract
The wild grapevine, Vitis vinifera L. ssp. sylvestris (Gmelin) Hegi, considered as the ancestor of the cultivated grapevine, is native from Eurasia. In Spain, natural populations of V. vinifera ssp. sylvestris can still be found along river banks. In this work, we have performed a wide search of wild grapevine populations in Spain and characterized the amount and distribution of their genetic diversity using 25 nuclear SSR loci. We have also analysed the possible coexistence in the natural habitat of wild grapevines with naturalized grapevine cultivars and rootstocks. In this way, phenotypic and genetic analyses identified 19% of the collected samples as derived from cultivated genotypes, being either naturalized cultivars or hybrid genotypes derived from spontaneous crosses between wild and cultivated grapevines. The genetic diversity of wild grapevine populations was similar than that observed in the cultivated group. The molecular analysis showed that cultivated germplasm and wild germplasm are genetically divergent with low level of introgression. Using a model-based approach implemented in the software structure, we identified four genetic groups, with two of them fundamentally represented among cultivated genotypes and two among wild accessions. The analyses of genetic relationships between wild and cultivated grapevines could suggest a genetic contribution of wild accessions from Spain to current Western cultivars.

Abstract
INTRODUCTION The promotion of different means of procuring both deceased and living organs (kidney and liver) is a necessity given the current organ shortage. Emergency department personnel are involved in the donation and transplantation process. Our objective was to analyze the attitude to the different kinds of organ donation of emergency services personnel in hospital centers in Spain and Mexico. MATERIALS AND METHODS A randomized sample was obtained from the "International Collaborative Donor Project" and was stratified according to emergency services and job category in nine hospitals, in Spain and in Mexico (n = 22). Attitude was evaluated using a validated survey. RESULTS Of the respondents, 76% were in favor of deceased organ donation and 24% were not in favor. This attitude toward deceased donation was associated with the respondent's country of origin, age, and job category; Mexicans (P = .036), younger respondents (P = .023), and physicians were most in favor (P < .001). With regard to attitude toward living kidney donation, 89% were in favor of related donation. Regarding living liver donation, 85% were in favor of related donation. In attitude toward living kidney and liver donation, relevant factors were related to donation and transplantation. CONCLUSIONS Professionals in emergency departments in hospital centers in Spain and Mexico had a favorable attitude toward the different kinds of donation, although it was less favorable than the attitude reported in other professional hospital groups.

Abstract
A considerable number of fatness QTL have been identified in growing pigs, but there is a lack of knowledge about the genetic architecture of this trait in gilts and sows. We have performed a genome scan, in 255 Iberian × Meishan F(2) sows, for backfat thickness (BF) at 150 (BF(150) ) and 210 (BF(210)) days of age, 30 days after conception (BF(30)) and 7-10 days before farrowing (BF(bf)). We have found one BF150 QTL in SSC6 (120 cM) that was highly significant (P < 0.001) at the chromosome-wide level and suggestive at the genome-wide level (P < 0.1). Ten additional chromosome-wide significant QTL were found for sow BF(150) (SSC1, SSC13), BF(210) (SSC6, SSC8, SSC15), BF(30) (SSC5, SSC6) and BF(bf) (SSC1, SSC6, SSC13). The location of several of the BF QTL varied depending on the growing and reproductive status of the sow, suggesting that part of these genetic effects may have a temporal pattern of phenotypic expression.

Abstract
INTRODUCTION Living donor kidney (LKD) transplantation provides better results than deceased donor donation, involving minimum risk for the donor. However, LKD donation rates are low in most countries. We analyzed attitudes toward LKD in transplant hospitals in Spain, Mexico, and Cuba. MATERIALS AND METHODS Data were obtained from five transplant hospitals through the International Collaborative Program "Proyecto Donante Vivo, Murcia" in three countries: Spain (n = 1168), Mexico (n = 903), and Cuba (n = 202). The random sample (2273 employees) was stratified according to job category. The instrument used to evaluate attitude was a validated questionnaire. Statistical analysis included Student t test, the chi(2) test, and multivariate analysis. RESULTS Eighty eight percent (n = 2002) of Spanish, Mexican, and Cuban transplant hospital personnel were in favor of related LKD and 24% nonrelated LKD (n = 555). Attitudes were more favorable among centers in Cuba 97% (n = 195), followed by Mexico 88% (n = 793) and by Spain 87% (n = 1014; P < .001). According to job category, 91% (n = 617) of physicians were in favor, 88% (n = 543) of nurses, 85% (n = 198) of health care assistants, and 85% (n = 198) of auxiliary personnel. Attitudes were related to variables of: attitude toward deceased donation (P < .001), discussion about organ donation and transplantation (P < .001), concern about body mutilation after donation (P = .001), a possible need for a transplant in the future (P < .001), and attitude toward living liver donation (P < .001). CONCLUSIONS Attitudes toward LKD in Hispanic/Latin Transplant Hospitals were favorable and could encourage an increase in LKD in the coming years assuming suitable sociopolitical and economic condition, as well as support from nephrologists.

Abstract
OBJECTIVE To evaluate in a canine model the induction of tolerance to renal transplantation after splenectomy and splenosis. MATERIALS AND METHODS This prospective, experimental, comparative, longitudinal study included 4 experimental groups, each comprising 4 dogs. Group 1 (control group) underwent renal transplantation only; group 2 underwent renal transplantation and splenectomy; group 3 underwent renal transplantation and splenosis; and group 4 underwent renal transplantation, splenectomy, and splenosis. Survival and degree of rejection were compared between the 4 groups. RESULTS Splenosis improved renal function after transplantation, as indicated by increased serum creatinine concentration (group 3, 6.2 mg/dL vs group 1, 12.9 mg/dL). Comparison of weighted survival curves (corrected for degree of rejection) demonstrated a significant difference between group 2 (66.0 days) and group 4 (66.2 days) vs group 1 (52.7 days) and group 3 (41.2 days) (P = .05, Wilcoxon rank sum test). CONCLUSION These results suggest that in this experimental model of renal transplantation, splenosis and splenectomy induce clinical tolerance, as indicated by improved renal function and prolonged recipient survival.

Abstract
Allograft recipients are exposed to risks owing to immunosuppression, and there is always the possibility that psychological issues interfere with the procedure's outcomes. An episode of blindness was suspected in a bilateral hand allograft recipient. The patient underwent a multidisciplinary evaluation, and clinical, electrophysiological, laboratory and a combination of functional and morphological magnetic resonance imaging (MRI) tests ruled out any visual process and revealed a secondary benefit, which turned out to be the use of privileges of the transplant support centre for several months. Composite tissue allograft recipients require a thorough psychological assessment before and after transplant procedures to prevent malingering.

Abstract
Small cell neuroendocrine tumor of the cervix is a rare malignancy with aggressive behavior. Metastases and recurrent disease are frequent and multimodal therapy is commonly used. Neoadjuvant or adjuvant chemotherapy should be combined with radiation therapy and surgery, even in early stages. Nevertheless, due to the low prevalence of these tumors, the best treatment has not yet been determined. Two cases of small cell neuroendocrine tumor of the uterine cervix are reported. We describe the clinical course, diagnostic methods and examine treatments applied and survival.

Abstract
Refinement of previous QTL on porcine chromosome 12 for fatty-acid composition and a candidate gene association analysis were conducted using an Iberian x Landrace cross. The concentrations of ten fatty acids were assayed in backfat tissue from which four metabolic ratios were calculated for 403 F2 animals. Linkage analysis identified two significant QTL. The first QTL was associated with the average chain length ratio and the percentages of myristic, palmitic and gadoleic acids. The second QTL was associated with percentages of palmitoleic, stearic and vaccenic acids. Based upon its position on SSC12, fatty acid synthase was tested as a candidate gene for the first QTL and no significant effects were found. Similarly, gastric inhibitory polypeptide (GIP) and acetyl-coenzyme A carboxylase alpha (ACACA) were tested as candidate genes for the second QTL using three SNPs in GIP and 15 synonymous SNPs in ACACA cDNA sequences. Two missense SNPs in GIP showed significant effects with palmitoleic and stearic fatty-acid concentration. Highly significant associations were found for two SNPs in ACACA with stearic, palmitoleic and vaccenic fatty-acid concentrations. These associations could be due to linkage disequilibrium with the causal mutations.

Abstract
Phosphorus deficiency is one of the major nutrient stresses affecting plant growth. Plants respond to phosphate (Pi) deficiency through multiple strategies, including the synthesis of high-affinity Pi transporters. In this study, the expression pattern of one putative wheat high-affinity phosphate transporter, TaPT2, was examined in roots and leaves under Pi-deficient conditions. TaPT2 transcript levels increased in roots of Pi-starved plants. A 579 bp fragment of the TaPT2 promoter is sufficient to drive the expression of the GUS reporter gene specifically in roots of Pi-deprived wheat. This TaPT2 promoter fragment was also able to drive expression of the GUS reporter gene in transgenic Arabidopsis thaliana, under similar growth conditions. Conserved regions and candidate regulatory motifs were detected by comparing this promoter with Pi transporter promoters from barley, rice, and Arabidopsis. Altogether, these results indicate that there are conserved cis-acting elements and trans-acting factors that enable the TaPT2 promoter to be regulated in a tissue-specific and Pi-dependent fashion in both monocots and dicots.

Abstract
Two polymorphisms of the porcine prolactin receptor (PRLR) gene were previously related to litter size by several authors; however, the magnitude and direction of such effects varied depending on the population analyzed. We have sequenced the complete coding region of the porcine PRLR gene and found 6 nonconservative SNP: C1217T (Leu/Pro406), C1283A (Asp/Ala428), G1439A (Lys/Arg480), T1528A (Met/Leu510), G1600A (Gly/Ser534), and G1789A (Gly/Ser597), within exon 10 of the gene, which encodes the entire intracytoplasmic domain of the protein. Eight haplotypes were found and were segregating at different frequencies in 6 porcine breeds. The effects of each individual SNP and haplotype were evaluated in an Iberian x Meishan F2 population using a univariate mixed-inheritance animal model. Significant effects on the number of corpora lutea were found for PRLR haplotypes (P < 0.012), confirming the previously reported associations of PRLR in this process and highlighting the importance of performing analysis of haplotypes rather than of individual SNP. Suggestive effects or tendencies were found for heart rate at birth (P < 0.10), rectal temperature (P < 0.05), and oxygen saturation (P < 0.10) 1 h after birth, and time to first suckle (P < 0.10). We found greater than expected levels of amino acid variability within the intracellular domain of the porcine PRLR, which have been associated with differences in the number of corpus lutea of sows and the preweaning survivability of piglets.

Abstract
The aim of this study was to investigate chromosomal regions affecting the number of teats in pigs and possible epistatic interactions between the identified quantitative trait loci (QTL). An experimental F2 cross between Iberian and Chinese Meishan lines was used for this purpose. A genomic scan was conducted with 117 markers covering the 18 porcine autosomes. Linkage analyses were performed by interval mapping using an animal model to estimate QTL and additive polygenic effects. Complementary analyses with models fitting two QTL were also carried out. The results showed three genomewide significant QTL mapping on chromosomes 5, 10 and 12, whose joint action control up to 30% of the phenotypic variance of the trait. Meishan alleles had a positive additive effect on teat number, and a positive-additive x additive-epistatic interaction was detected between QTL on chromosomes 10 and 12.

Abstract
Niche apportionment models have only been applied once to parasite communities. Only the random assortment model (RA), which indicates that species abundances are independent from each other and that interspecific competition is unimportant, provided a good fit to 3 out of 6 parasite communities investigated. The generality of this result needs to be validated, however. In this study we apply 5 niche apportionment models to the parasite communities of 14 fish species from the Great Barrier Reef. We determined which model fitted the data when using either numerical abundance or biomass as an estimate of parasite abundance, and whether the fit of niche apportionment models depends on how the parasite community is defined (e.g. ecto, endoparasites or all parasites considered together). The RA model provided a good fit for the whole community of parasites in 7 fish species when using biovolume (as a surrogate of biomass) as a measure of species abundance. The RA model also fitted observed data when ecto- and endoparasites were considered separately, using abundance or biovolume, but less frequently. Variation in fish sizes among species was not associated with the probability of a model fitting the data. Total numerical abundance and biovolume of parasites were not related across host species, suggesting that they capture different aspects of abundance. Biovolume is not only a better measurement to use with niche-orientated models, it should also be the preferred descriptor to analyse parasite community structure in other contexts. Most of the biological assumptions behind the RA model, i.e. randomness in apportioning niche space, lack of interspecific competition, independence of abundance among different species, and species with variable niches in changeable environments, are in accordance with some previous findings on parasite communities. Thus, parasite communities may generally be unsaturated with species, with empty niches, and interspecific interactions may generally be unimportant in determining parasite community structure.

Abstract
The parasite community of animals is generally influenced by host physiology, ecology, and phylogeny. Therefore, sympatric and phylogenetically related hosts with similar ecologies should have similar parasite communities. To test this hypothesis we surveyed the endoparasites of 5 closely related cheilinine fishes (Labridae) from the Great Barrier Reef. They wereCheilinus chlorourus,C. trilobatus,C. fasciatus,Epibulus insidiatorandOxycheilinus diagramma. We examined the relationship between parasitological variables (richness, abundance and diversity) and host characteristics (body weight, diet and phylogeny). The 5 fishes had 31 parasite species with 9–18 parasite species per fish species. Cestode larvae (mostly Tetraphyllidea) were the most abundant and prevalent parasites followed by nematodes and digeneans. Parasites, body size and diet of hosts differed between fish species. In general, body weight, diet and host phylogeny each explained some of the variation in richness and composition of parasites among the fishes. The 2 most closely related species,Cheilinus chlorourusandC. trilobatus, had broadly similar parasites but the other fish species differed significantly in all variables. However, there was no all-encompassing pattern. This may be because different lineages of parasites may react differently to ecological variables. We also argue that adult parasites may respond principally to host diet. In contrast, larval parasite composition may respond both to host diet and predator-prey interactions because this is the path by which many parasites complete their life-cycles. Finally, variation in parasite phylogeny and parasite life-cycles among hosts likely increase the complexity of the system making it difficult to find all-encompassing patterns between host characteristics and parasites, particularly when all the species in rich parasite communities are considered.

Abstract
With the aim of achieve a better understanding of the epidemiology and distribution of bovine leukaemia virus (BLV) infection in Chile, we assessed the suitability of using DNA isolated from the leukocyte fraction of bulk milk samples to carry out PCR-RFLP and DNA sequence analysis. The env fragment of BLV was successfully amplified from 33 serologically positive bulk milk samples collected from different geographical areas in the south of Chile. Restriction analysis allowed to classify 17 isolates within the Australian subgroup and 16 within the Belgium subgroup. DNA sequence and multiple alignment analysis of eight Chilean isolates showed a significantly higher frequency of single and double nucleotide substitutions. Most of these mutations were non-silent, resulting in changes at the protein level in several important epitopes of gp51. The Chilean sequences and 59 BLV env sequences available at GenBank, were subjected to a phylogenetic analysis, resulting in four different clusters. The groups identified were not related to those previously defined by restriction analysis. Chilean isolates were included in two different clusters and were genetically not related to isolates collected from neighbouring countries. Considering our results we can conclude: (i) bulk milk samples are suitable to identify the presence of BLV allowing epidemiological and genetic studies to be conducted on large geographical areas; (ii) at least four different genetic groups of BLV were identified by phylogenetic analysis, with Chilean isolates included in two different sub clusters.

Abstract
Chagas disease caused by infection with Trypanosoma cruzi Chagas (Kinetoplastida: Trypanosomatidae) is widespread in Mexico, transmitted by various triatomine bugs (Hemiptera: Reduviidae). The only domestic vector in Cuernavaca (population 650 000) is Triatoma pallidipennis (Ståhl) with T. cruzi seroprevalence ranging from 1% to 9% in the resident human population. We surveyed possible risk factors for T. pallidipennis infestation at Cuernavaca (altitude 1200-2200 m) on south-western slopes of the Sierra Madre Occidental. This metropolitan area (with five administrative counties) has rapid urbanization, forested environs and proliferation of 'weekend housing' for visitors from Mexico City, 60 km to the north. To assess factors associated with T. pallidipennis infestation, we first stratified Cuernavaca by altitude and by socio-economic status of population catchment units (PCUs). Within each PCU, one to three blocks were chosen for cluster sampling (three houses/block) and information about Chagas disease was distributed. After obtaining signed consent from householders, representative houses were routinely and opportunistically inspected for T. pallidipennis and surveyed for demographic, economic, physical and other potential risk factors. Of the 1129 houses assessed, T. pallidipennis was found in 4.1% (range 3.0-6.8% per county) and the T. cruzi infection rate was approximately 50% in bugs. Rates of house infestation in poor PCUs were double those in higher socio-economic strata (odds ratio 2.12, confidence interval 1.03-4.3), with >4-fold greater crowding index of T. pallidipennis. The bug density index was inversely correlated with PCU altitude and socio-economic category (altitude of homes being associated with prosperity), while the bug colonization index (presence of nymphs indicating breeding) did not vary significantly across the PCU categories, but did vary according to altitude. Multivariate regression analysis showed that the most significant risk factors associated with T. pallidipennis infestation were lower altitude (linked with lower socio-economic status), garden area >80 m(2), dogs at liberty to enter the house, occurrence of squirrels and opossums around the house, presence of pigs in the surrounding area and having at least one of the adjacent lots empty (unconstructed). Householders who had received information about Chagas disease comprised 33% from infested houses (14/42) but only 15% from non-infested houses (148/984). Hence, the awareness of Chagas disease was significantly associated with having a bug-free house (P < 0.01). When shown specimens of T. pallidipennis, the proportions of householders who recognized them were 78% from infested houses but only 29% of those with uninfested houses. Given the low infestation rates and the high capacity of the population to act appropriately once they have received information regarding this disease and its vector, relevant health education is expected to have a significant impact on triatomine control in this metropolitan area.

Abstract
Genes encoding the oestrogen receptors (ESR) are considered candidate genes for prolificacy traits due to the key role these molecules play in the regulation of reproductive physiology. In this paper, we report the assignment of the pig ESR2 gene to porcine chromosome 1 by radiation hybrid mapping. Most of the ESR2 cDNA was sequenced from Iberian pig ovarian RNA samples and one A/G single nucleotide polymorphism (SNP) was found at exon 5, being associated with a Met/Val substitution at position 949. This SNP was genotyped using a PCR-RFLP (Hsp92II) protocol and its potential effect on litter size was evaluated in two Iberian pig populations. However, no statistically significant association between the ESR2 polymorphism and litter size was found.

Abstract
With approximately 90 million cases annually, infection with Chlamydia trachomatis is the most prevalent sexually transmitted bacterial disease in the world. Considering that these infections are often asymptomatic and cause major complications like acute pelvic inflammatory disease, ectopic pregnancy, infertility or infant pneumonia, the estimated costs for diagnosis and treatment in the USA amounts to 2.2 million US dollars for each 500 cases. Therefore, there is a high need for correct, quick and cost-effective diagnosis and treatment of this urogenital tract infection. New innovative therapies provide good results with regard to efficacy and patients' compliance. The success rates of treatments are at least 95%. However, the occurrence of antibiotic resistance should not be ignored and new treatment schemes must be developed. The state-of-the-art of diagnosis and treatment of chlamydial infections as well as the pathophysiology is discussed in this review. In conclusion, infections with C. trachomatis is an important public health problem, especially in third world and developing countries, and more socio-economic studies linking secondary prevention of chlamydial infections, infertility and adverse pregnancy outcome are needed to understand more of its aetiology. In addition, diagnosis and treatment should be improved. Data in men revealed that past infections but not present infections are more related to male infertility. There is still controversial results. In future studies, function of the seminal vesicles and evaluation of the antioxidant capacity should be taken into account when role of C. trachomatis infection on male fertility is assessed.

Abstract
In cases with previous photorefractive keratectomy (PRK), there is a risk of developing severe haze after laser in situ keratomileusis (LASIK). We report 3 patients (4 eyes) who developed severe haze after LASIK treatment for residual myopia following PRK. Both PRK and LASIK procedures were performed using the VISX 20/20 excimer laser. We report the grade of haze, amount of regression, and visual acuity after the patients were treated with topical steroids. In 2 eyes, the uncorrected visual acuity was 1.0 after 1 year with grade I haze. In the other 2 eyes, there was a residual refractive error, and the best spectacle-corrected visual acuity was 0.7 with grade II haze.

Abstract
A new nematode belonging to the Cystidicolidae is described, Pseudascarophis genypteri n. sp. was found in the intestine of the red ling Genypterus chilensis, sampled off Talcahuano, Chile. It is distinguished from Ascarophis species mainly by the absence of cephalic papillae and of submedial and medial labia. The other species in the genus, Pseudascarophis kyphosi Ko, Margolis, and Machida, 1985, found in Kyphosus cinerascens, and P. tropica (Solov'eva, 1996), found in Parupeneus chrysopleuron, differed principally from P. genypteri in the form of pseudolabia, number of pre- and postanal papillae, and length of spicules.

Abstract
PURPOSE To evaluate laser in situ keratomileusis (LASIK) in the management of overcorrection and undercorrection after radial keratotomy (RK). SETTING Instituto Oftalmológico de Alicante, Alicante, Spain. METHODS This prospective study comprised 20 eyes of 13 patients. The eyes were divided into 2 groups: 11 eyes that were overcorrected after RK and 9 eyes that were undercorrected after RK. Both groups were treated with LASIK after a mean interval of 22 months +/- 8.4 (SD) (range 12 to 45 months). The follow-up was 6 months. RESULTS Six months after LASIK, there was a significant decrease in the spherical equivalent in both groups. Ninety-one percent of eyes in the overcorrected group and 89% in the undercorrected group were within +/-1.0 diopter of the intended correction. There was a significant improvement in the uncorrected visual acuity in both groups. In the overcorrected group, 91% showed no change or improvement in their best corrected visual acuity; in the undercorrected group, 89% showed no change or improvement. CONCLUSIONS Laser in situ keratomileusis was relatively safe in treating both overcorrection and undercorrection after RK. With proper intraoperative precautions, LASIK can effectively treat the residual refractive defects after RK.
