Abstract
Increasingly potent immunosuppressive agents have reduced the incidence of rejection of transplanted organs while increasing patient susceptibility to opportunistic infections and cancer. Adenoviruses are increasingly recognized as contributors to morbidity and mortality in stem cell and solid-organ transplant recipients. Clinical findings range from asymptomatic viremia to respiratory and gastrointestinal disease, hemorrhagic cystitis, and severe disseminated illness. We describe the first case in Chile of hemorrhagic adenovirus cystitis after renal transplantation in an adult.

Abstract
Helminth eggs are the pathogens most resistant to inactivation during sludge and wastewater treatment. For this reason, in several regulations and the WHO guidelines for wastewater and excreta reuse for agriculture and aquaculture they are considered as indicators of the performance of the treatment process. Conditions required to inactivate helminth eggs, notably Ascaris lumbricoides, are recommended in the literature, but in practice these have not always proven effective, not only for Ascaris but also other genera of helminth eggs. The objective of this research was to study the inactivation of a high total content of non larval Ascaris and other genera of helminth eggs of medical importance to developing countries under controlled conditions of (a) temperature (30 °C to 80 °C) and humidity (80, 90 and 95%) and (b) lime doses (15 and 20% of CaO w/w dry basis) and humidity (90 and 80%), using different contact times in both cases. The inactivation data obtained for different genera of non larval helminth eggs is presented. Results showed that there is a combination of conditions (temperature, pH and humidity) that is optimal for inactivation. To completely inactivate any genera of non larval helminth eggs: (a) a temperature above 70 °C and 80% humidity for a duration of 120 min; and, (b) a 20% CaO dose (pH 12.5) and a humidity level of 80% for a duration of 8 months are needed. With regard to the resistance of different genera of helminth eggs, Ascaris, Toxocara and Taenia, in that order, were the most resistant, while the most sensitive were Trichuris and Hymenolepis. For most of the conditions tested Ascaris showed the highest resistance, probably due to the chemical arrangement of its membrane.

Abstract
OBJECTIVE The purpose of this study was to evaluate the importance of various factors on 1-year serum creatinine (SCr) as a surrogate endpoint for allograft survival among a series of kidney transplantations performed at 2 centers. PATIENTS AND METHODS Two hundred sixty consecutive renal transplantations were included with overall mean age of 40 +/- 13 years, including 55% men and 19% living donor grafts. Factors considered for analysis were donor and recipient ages, and sexes, number of transplantations, panel-reactive antibodies, total number of HLA mismatches, cold ischemia time (CIT), acute rejection (AR) rate, and presence/duration of delayed graft function (DGF). Multiple regression analyses were performed for 1-year SCr, AR rate, and DGF duration. RESULTS One-year SCr was 1.46 +/- 0.5 mg/dL, 6-month AR rate was 22%, and DGF rate was 29% of mean duration 3 +/- 8 days. Multiple regression analysis for lower 1-year SCr value identified as significant female recipient sex, lower donor age, absence of AR within 6 months, and decreased DGF duration (P < .05). The only significant factor affecting AR rate was DGF duration. Finally, prolonged CIT was associated with a longer DGF duration. CONCLUSIONS We confirmed that 1-year SCr was primarily affected by well-known factors, such as AR incidence, donor age, and female recipient sex. However, we identified DGF duration as a significant factor affecting 1-year SCr. AR rate was also associated with DGF duration, which in turn depended upon longer CIT.

Abstract
The energy spectrum of cosmic rays above 2.5 x 10;{18} eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the particle flux, J proportional, variantE;{-gamma}, at energies between 4 x 10;{18} eV and 4 x 10;{19} eV is 2.69+/-0.02(stat)+/-0.06(syst), steepening to 4.2+/-0.4(stat)+/-0.06(syst) at higher energies. The hypothesis of a single power law is rejected with a significance greater than 6 standard deviations. The data are consistent with the prediction by Greisen and by Zatsepin and Kuz'min.

Abstract
The CD209 gene family that encodes C-type lectins in primates includes CD209 (DC-SIGN), CD209L (L-SIGN) and CD209L2. Understanding the evolution of these genes can help understand the duplication events generating this family, the process leading to the repeated neck region and identify protein domains under selective pressure. We compiled sequences from 14 primates representing 40 million years of evolution and from three non-primate mammal species. Phylogenetic analyses used Bayesian inference, and nucleotide substitutional patterns were assessed by codon-based maximum likelihood. Analyses suggest that CD209 genes emerged from a first duplication event in the common ancestor of anthropoids, yielding CD209L2 and an ancestral CD209 gene, which, in turn, duplicated in the common Old World primate ancestor, giving rise to CD209L and CD209. K(A)/K(S) values averaged over the entire tree were 0.43 (CD209), 0.52 (CD209L) and 0.35 (CD209L2), consistent with overall signatures of purifying selection. We also assessed the Toll-like receptor (TLR) gene family, which shares with CD209 genes a common profile of evolutionary constraint. The general feature of purifying selection of CD209 genes, despite an apparent redundancy (gene absence and gene loss), may reflect the need to faithfully recognize a multiplicity of pathogen motifs, commensals and a number of self-antigens.

Abstract
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau neutrinos that interact in Earth's crust. Tau leptons from nu(tau) charged-current interactions can emerge and decay in the atmosphere to produce a nearly horizontal shower with a significant electromagnetic component. The data collected between 1 January 2004 and 31 August 2007 are used to place an upper limit on the diffuse flux of nu(tau) at EeV energies. Assuming an E(nu)(-2) differential energy spectrum the limit set at 90% C.L. is E(nu)(2)dN(nu)(tau)/dE(nu)<1.3 x 10(-7) GeV cm(-2) s(-1) sr(-1) in the energy range 2 x 10(17) eV< E(nu)< 2 x 10(19) eV.

Abstract
AIMS The study aim was to determine the presence of total and faecal coliforms on kitchen surfaces, in tap water and on the hands of caregivers in households on both sides of the US-Mexico border. METHODS AND RESULTS Samples were collected in 135 randomly selected households in Ciudad Juarez, Mexico, and El Paso, Texas. Different surfaces throughout the kitchen and head of households' hands were sampled using sterile cotton swabs moistened in D/E neutralizing solution. Sponge/dishcloth and drinking water samples were also obtained. Total and faecal coliforms were enumerated on m-Endo LES and mFC respectively. Total coliforms and Escherichia coli in drinking water samples were enumerated in accordance with the Quanti-Tray method. Sponge/dishcloth samples were the most commonly contaminated kitchen sites, followed by countertops and cutting boards. We recovered faecal coliforms from 14% of the hands of child caregivers, and this indicator was moderately associated with self-reported failure to wash hands after using the toilet (OR = 3.2; 95% CI: 0.9, 11.1). CONCLUSIONS Hand washing should continue to be emphasized, and additional interventions should be directed to specific kitchen areas, such as sponges/dishcloths, tables/countertops and cutting boards. SIGNIFICANCE AND IMPACT OF THE STUDY There is a need for additional interventions regarding kitchen sanitation.

Abstract
PURPOSE Despite known cholesterol lowering effects the use of psyllium husk (Plantaginis ovatae testa) in Germany for hypercholesterolemia is limited compared to their use as a laxative. To investigate whether use in hypercholesterolemia is limited due to adverse effects on the gastrointestinal system, a prospective observational study was conducted. METHODS Sixty-two outpatients with documented hypercholesterolemia and complaints of constipation were identified from an academic clinical center. Treatment with 3.5g psyllium husk preparation administered three times daily was initiated and patients were monitored at weekly intervals. Gastrointestinal symptoms were quantified using a validated Nepean Dyspepsia Index modified to identify both upper and lower abdominal symptoms. Diaries and study medication records were used to evaluate compliance. RESULTS Fifty-four of 62 patients enrolled in the study completed the study protocol with 4 subjects discontinuing due to adverse reactions associated with psyllium husks. Total cholesterol was significantly decreased from 252+/-39mg/dl before treatment to 239+/-37mg/dl after 3 weeks of treatment. Similarly, low density lipoprotein (LDL)-cholesterol decreased from 174+/-34 to 162+/-31mg/dl during the study. Triglycerides and high density lipoprotein (HDL) were unchanged. Gastrointestinal symptoms were rated lower at the end than at the beginning of the study. In week 1 most of the patients reported gastrointestinal symptoms and also gastrointestinal adverse reactions, which however, showed a decrease from week 1 to weeks 2 and 3 in the diaries. Patient response to study medication was positive for patients completing the study. CONCLUSIONS Psyllium husk preparations may be a therapeutic option for patients with mild to moderately elevated cholesterol levels. Adverse gastrointestinal symptoms associated with the preparation appear to be transient in some of the patients. Compliance may be optimized with adequate patient counseling.

Prevalence and determinants of high-risk human papillomavirus (HPV) infection and cervical cytological abnormalities in imprisoned women. Epidemiol Infect 2008; 136:215-21. [PMID: 17445312 PMCID: PMC2870800 DOI: 10.1017/s0950268807008382] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/21/2007] [Indexed: 11/06/2022] Open
Abstract
The aim of the study was to estimate the prevalence and risk factors associated with infection by high-risk human papillomavirus (HR-HPV) in cervix and squamous intra-epithelial lesions (SIL) in imprisoned women. This was done by a cross-sectional study of imprisoned women attending the gynaecological clinic in Foncalent prison in Alicante, Spain. The study period was from May 2003 to December 2005. HR-HPV infection was determined through Digene HPV Test, Hybrid Capture II (HC-II). HPV typing was determined by multiplex nested PCR assay combining degenerate E6/E7 consensus primers. Multiple logistic regression modelling was used for the analysis of associations between variables where some were considered possible confounders after checking for interactions. A total of 219 women were studied. HR-HPV prevalence was 27.4% and prevalence of SIL was 13.3%. HIV prevalence was 18%, higher in Spaniards than in migrant women (24.6% vs. 14.3%, P<0.05). In multivariate analyses, risk factors for HPV infection were younger age (P for trend=0.001) and tobacco use (OR 2.62, 95% CI 1.01-6.73). HPV infection (OR 4.8, 95% CI 1.7-13.8) and HIV infection were associated with SIL (OR 4.8, 95% CI 1.6-14.1). The commonest HPV types were HPV16 (29.4%), HPV18 (17.6%), HPV39 (17.6%) and HPV68 (17.6%). The prevalence of both HR-HPV infection and SIL in imprisoned women found in this study is high. Determinants for each of the outcomes studied were different. HPV infection is the most important determinant for SIL. A strong effect of HIV co-infection on the prevalence of SIL has been detected. Our findings reinforce the need to support gynaecological clinics in the prison setting.

Abstract
OBJECTIVES To evaluate the practical utility of the PiCCO system for monitoring cardiac output and its derived variables during lung resection surgery. PATIENTS AND METHODS Patients scheduled for lung resection surgery were enrolled. After anesthesia had been induced, a Pulsiocath catheter was placed in the femoral artery ipsilateral to the thoracotomy. The following parameters were evaluated: ease of placement of the arterial catheter, functioning of the system, and appearance of complications. When the catheter was connected to the PiCCO monitor, cardiac output and derived variables were recorded throughout the procedure. RESULTS Fifteen patients were enrolled in the study. Placement of the catheter in the femoral artery was easy in 9 cases (60%), difficult in 4 cases (27%), and impossible in 2 cases (13%). The catheter functioned correctly in 7 patients but problems developed in 6 patients (2 cases of a poor-quality pressure curve, 1 case of a discrepancy of more than 20% in comparison with blood pressure, and 3 cases of impossibility of extracting blood samples through the arterial catheter because the patients were in a lateral decubitus position). No complications relating to arterial puncture were observed. Hemodynamic monitoring showed increased cardiac output after surgery. CONCLUSIONS The results suggest that using the PiCCO system during lung resection surgery is of limited utility, given that problems developed in relation to 53% of the catheters. This makes the technique unreliable in the event of its being required.

Abstract
A constitutive model for describing the mechanical response of an amorphous glassy polycarbonate is proposed. The model is based on an isotropic elastic phase surrounded by an SO(3) continuum of plastic phases onto which the elastic phase can collapse under strain. An approximate relaxed energy is developed for this model on the basis of physical considerations and extensive numerical testing, and it is shown that it corresponds to an ideal elastic-plastic behavior. Kinetic effects are introduced as rate-independent viscoplasticity, and a comparison with experimental data is presented, showing that the proposed model is able to capture the main features of the plastic behavior of amophous glassy polycarbonate.

Abstract
AIM To develop a scale to assess the severity of hepatic encephalopathy using simple dichotomic items. METHODS A list of 48 items was created by selecting items that are simple to recognize and categorize; it was applied to thirty-six cirrhotic in-patients with episodic encephalopathy, in addition to the adapted-West-Haven Criteria and the Glasgow Coma Score. The list underwent an item reduction process and principal component analysis; the metric characteristics were evaluated. RESULTS Multiple neurological abnormalities were observed and a Clinical Hepatic Encephalopathy Staging Scale of nine items was constructed. The principal component analysis of the Clinical Hepatic Encephalopathy Staging Scale obtained two factors that explained 77% of the variance. The Clinical Hepatic Encephalopathy Staging Scale exhibited adequate internal consistency and reproducibility. The scores of the Clinical Hepatic Encephalopathy Staging Scale correlated to those of adapted-West-Haven Criteria and the Glasgow Coma Score. CONCLUSIONS This study confirms that the evaluation of multiple neurological manifestations is not necessary to classify hepatic encephalopathy adequately, which can be simply undertaken by an assessment of the patient's orientation, alertness, ability to respond to commands and to talk. A list of nine items is proposed as a linear scale from normality (Clinical Hepatic Encephalopathy Staging Scale = 0) to deep coma (Clinical Hepatic Encephalopathy Staging Scale = 9).

Abstract
We report a patient who developed type II heparin-induced thrombocytopenia (HIT) and accidentally received a recombinant hirudin (r-hirudin) overdosage. Treatment with hemodialysis (HD) using high-flux polysulfone dialyzer and hemofiltration was performed. Length of treatment was adjusted, monitoring activated partial thromboplastin time (aPTT) to 1.5-2.5 times the mean of the normal range. She developed deep venous thrombosis and occlusion of vascular access. Only after cessation of heparin lock catheter, platelet count began to increase. After one year of treatment with acenocoumarol and additional low-dose r-hirudin, neither bleeding nor thrombotic episodes have been reported.

Abstract
UNLABELLED Sclerosing Encapsulating Peritonitis (SEP) is a rare but serious complication of continuous ambulatory peritoneal dialysis (CAPD) with a high morbi-mortality. We describe our experience with patients was diagnostic of SEP, their characteristics in CAPD and their clinic evolution after diagnosis. 190 CAPD patients were follow-up during 17 years. Eight patients (4.2%) developed SEP. Average age 45+/-14 years (range 29-64 years), four was male. Time in CAPD was 72+/-29 months (range 24-120 months). All patients have peritonitis previously (mean 3+/-1). We observe a change in peritoneum characteristics (D/P Cr 4), with an average of 0.6+/-0.1 at one year of CAPD, versus 0.82+/-0.08 at the end of CAPD, with statistic significance (p<0.001). There are increases in use of hypertonic bags: 53%+/-28 at beginning versus 91%+/-27 at end, with statistic significance (p<0.009). All patients show tendency to hyperphosphoremia (mean 6.7+/-0.7 mg/dl), with product calcium-phosphorus 68.4+/-8.3. Five patients (62.5%) have a previous renal transplant, one lost due to early graft thrombosis and two lost due to acute rejection. Six patients (75%) have a previous abdominal surgery, although was extra peritoneal in all cases. The diagnosis of SEP was clinic suspicion in all cases, suggestive radiological data (intestinal handle group) and laparoscopy showing SEP (cocoon) with histological confirmation (fibrosis and peritoneal calcification) in four cases. The treatment was medical in six cases associated with surgery in four of them. The medical treatment was tamoxifen and/or corticosteroids, associated with total parenteral nutrition in two patients and enteral nutrition in one. Surgery in six patients: three as urgent surgery (all died) and three as programme surgery (two live still). Etiology of died was: three for sepsis, one for peritonitis after bowel perforation, one for severe problems of nutrition. The average survival of three patients alive was 38+/-17 months, two of them had programme surgery, and one with functioning transplant we opt for conservative treatment. The actuarial survival at 24 months was 51%. CONCLUSION The SEP is a serious entity with high mortality. Although our short experience doesn't can indicate a concrete treatment, our personal impression is that early surgery associated with corticosteroids treatment may improve the prognostic.

Abstract
BACKGROUND The sustained elevation of phosphorous among patients with end-stage renal failure is associated with elevated mortality rates. Phosphate binding agents are usually necessary to control serum phosphate levels. Phosphate removal during dialysis is limited largely due to the intracellular location of most inorganic phosphorous. The membrane surface, the frequency and the duration of therapy have proved to be very important factors in the serum phosphate control. THE AIM of our work is to investigate the influence on phosphate removal of factors that normally participate in the haemodialysis session: Plasma phosphate level (Php), treatment duration, membrane surface, high or low-flux membranes, the vascular access, dialysate flux , the volume of blood passing through the dialyzer (L) in each dialysis session and the blood flow during the first hour of dialysis. On 16 patients, we also had the possibility of comparing phosphate removal with 1.8 m(2) high-flux haemodialysis, 1.8 m(2) on-line hemodiafiltration and the on-line technique with the new Helixone dialyzer Fresenius Fx100. METHODS 108 haemodialysis patients, 62% men, 38% women aged 21-82 years (61+/-14;mean+/-sem),) were selected for the study. Mean treatment time 4.14+/-0.41 hours (range 3.5-5 hours). The vascular access was an arterio-venous fistula in eighty five (78%) and a double lumen tunnelled catheter 23 (22%). Patients were studied under their normal every day conditions. High-flux membrane was used by 31 (30%) patients and low-flux membrane by 77 (70%). Membrane surface was: 1.7 m2:17 (16%); 1.8 m2:77 (71%); 2,1 m2:14 (13%). Dialysate flux was: 500 ml/min. 55 patients; 700 ml/min: 53 patients. In 16 out of 108 patients we had the possibility of using on-line hemodiafiltration with ultrapure bicarbonate-buffered dialysate. Phosphate mass removal (MPO4) was calculated using the formula:MPO4=0.1 t-17+50 Cds 60+11Cb 60 (1), where t is treatment time in minutes, Cds60 and Cb60 are phosphate concentrations in dialysate and plasma measured at 60 min from the beginning of hemodialysis in mg/dl, and MPO4 is the estimated phosphate removed in mg/treatment. RESULTS We found a good correlation between phosphate removal and serum phosphate levels (p=0.01), but not with the membrane surface or treatment duration. Phosphate removal was 640+/-180 mg/session with low-flux membrane and 700+/-170 mg/session with high-flux membrane (p=0.280). The MPO4 was 720+/-190 mg/treatment in patients with a AV fistula and 620+/-180 in patients with a tunnelled catheter (p=0.023). We found a good correlation between phosphate removal and the volume of blood (L) that passed the dialyzer in each session (r=0.001) but we did not find a correlation between phosphate removal and KT/Vurea, the dialysate flux or the ultra filtration. On-line technique did not increased the MPO4(733+/-280 mg, p=0.383). The on-line technique with the new dialyzer (Fresenius Fx100), increased the phosphate removal to 759+/-199 mg/session (p=0.057). CONCLUSION Phosphate removal during dialysis is influenced by Plasma phosphate levels, the volume of blood that passed the dialyzer and the vascular access. Uniformity on time and membrane surface could explain the abs cense of influence in our case. The ultra filtration, dialysate flux, membrane permeability or on-line hemodiafiltration does not influence the phosphate removal. The new membrane helixone with 2,1 m2 (Fresenius Fx100) increases phosphate removal probably because the membrane surface is higher.

Abstract
The aim of this study is to determine oncogenic human papillomavirus (HPV) types and HPV type 16 (HPV16) variant distribution in two Spanish population groups, commercial sex workers and imprisoned women (CSW/IPW) and the general population. A multicenter cross-sectional study of 1,889 women from five clinical settings in two Spanish cities was conducted from May to November 2004. Oncogenic HPV infection was tested by an Hybrid Capture II (HC2) test, and positive samples were genotyped by direct sequencing using three different primer sets in L1 (MY09/11 and GP5+/GP6+) and E6/E7. HPV16 variants were identified by sequencing the E6, E2, and L1 regions. Four hundred twenty-five samples were positive for the HC2 test, 31.5% from CSW/IPW and 10.7% from the general population. HPV16 was the most frequent type. Distinct profiles of oncogenic HPV type prevalence were observed across the two populations. In order of decreasing frequency, HPV types 16, 31, 58, 66, 56, and 18 were most frequent in CSW/IPW women, and types 16, 31, 52, 68, 51, and 53 were most frequent in the general population. We analyzed HPV16 intratype variants, and a large majority (78.7%) belonged to the European lineage. AA variants were detected in 16.0% of cases. African variants belonging to classes Af1 (4.0%) and Af2 (1.3%) were detected. Different HPV types and HPV16 intratype variants are involved in oncogenic HPV infections in our population. These results suggest that HPV type distribution differs in CSW/IPW women and in the general population, although further analysis is necessary.

Abstract
OBJECTIVES To estimate prevalence and determinants of high risk (HR) human papillomavirus (HPV) by country of origin in women attending a family planning centre (FPC) in Alicante, Spain. METHODS Cross sectional study of all women attending a FPC from May 2003 to January 2004. An ad hoc questionnaire was designed and data were collected prospectively. HR HPV infection was determined through the Digene HPV test, Hybrid Capture II, and positive samples for PCR were directly sequenced. Data were analysed through multiple logistic regression. RESULTS HR HPV prevalence in 1011 women was 10% (95% CI: 8.2 to 12). Compared to Spaniards (prevalence 8.2%) HR HPV prevalence in Colombians was 27.5% (OR: 4.24 95% CI: 2.03 to 8.86), 23.1% in Ecuadoreans (OR: 3.35 95% CI: 1.30 to 8.63), and 22.73% in women from other Latin American countries (OR: 3.29 95% CI: 1.17 to 9.19). Women with more than three lifetime sexual partners had an increased risk of HR HPV infection (OR 3.21 95% CI: 2.02 to 5.10). The higher risk of HR HPV infection was maintained in Latin American women in multivariate analyses that adjusted for age, number of lifetime sexual partners, and reason for consultation. The commonest HPV types in women with normal cervical smears were HPV-18 (20%), HPV-16 (14%) and HPV-33 (11%). CONCLUSIONS Prevalence of HR HPV is more than three times higher in Latin Americans than in Spaniards. Latin American women's HPV prevalence resembles more that of their countries of origin. It is essential that health service providers identify these women as a priority group in current cervical screening programmes.
