Death is not only a universal biological fact; for the individual it is the "event horizon". This fact has important symbolic meanings and complex social consequences. Any society, secular or not, must manage this reality. What response is given to the question of religious phenomenon in general, and to funerary practices in particular, in a secular society in which individuals with different religious sensibilities coexist? This article aims to analyse the response given by the Spanish state to the questions raised regarding burials by Muslim communities, the most widespread minority group in Spain as a whole. This response, which would be framed within what could be called a 'cooperation model', has encountered some difficulties as a result of the territorial organisation of the Spanish state. Despite this, the willingness to cooperate on the part of both the administrations that make up the state and the Islamic communities has made a situation of stable coexistence possible.

Gambling is an international phenomenon, posing a serious threat to adolescents who begin gambling at a young age. This study aims, to explore gambling behavior in adolescents and interpret its risk factors. We conducted a three-waves cohort longitudinal study assessing gambling and associated risk factors in south-eastern Spain. Data were analyzed using the Capabilities, Opportunities, Motivations, Behavior (COM-B) model and the partial least squares path modelling (PLS-PM) technique. Gambling was measured by frequency and money spent; associated factors were knowledge about gambling, parental attitude towards gambling, risk perception, normative perception, and intention to gamble. These items were assigned as indicators of each construct of the COM-B model—capability, opportunity, motivation, and behavior—using the theoretical domains framework. Once the behavior was performed, feedback on future capability, opportunity, and motivation was observed. Results show that capability, determined by past experience, and opportunity, determined by parental attitudes, motivates adolescents to seek gambling experiences in the future. Identifying such factors that affect gambling behavior in adolescents and establishing relationships between them through a robust theoretical model is essential for designing effective interventions.

Abstract: Killer cell immunoglobulin-like receptors (KIRs) are regulators of cytolytic activity of natural killer and certain T cells through interactions with human leukocyte antigen (HLA) class I ligands. KIRs have been shown to contribute to the pathogenesis of several autoimmune diseases, but their role in multiple sclerosis (MS) is still unclear. Here we determined the influence of KIR genes and their HLA class I ligands on susceptibility to MS and on the response to interferon-beta treatment in a Spanish population. KIR and HLA genotyping were performed in 200 MS patients and 200 controls. Significantly higher frequencies were found for KIR2DL5 and KIR3DS1 genes in MS patients and the carriage of the KIR2DL1 gene was associated with a higher progression index. Moreover, the frequency of the HLA-Bw4 motif was significantly reduced in MS patients. The KIR2DL1 and HLA-C2 matches were more frequent in MS patients, whereas the KIR3DL1 and HLA-Bw4 matches were more frequent in healthy controls. Nevertheless, non significant associations were found between all the KIR genes and therapeutic response to interferon-beta. Our results confirm that the carriage of HLA-Bw4 is a protective factor in MS and suggest that KIR2DL5 and KIR3DS1 may have a predisposing role in the disease. [Copyright &y& Elsevier]

This paper analyzes the psychosocial variables that make up the profile of the university entrepreneur in Spain from the perspective of the entrepreneurial intention. A career development model is used to classify these psychosocial variables in three settings: family, workplace and personal issues. The sample consisted of 601 university students from the autonomous region of Castilla y Le6n. The results show that the students develop high intentions to work as employees for private companies or for the Administration but their intentions to become entrepreneurs are low. Specifically, we found that gender, family, labor experience, entrepreneurial training, social support, barriers perception and individualistic and coUectivistic values are likely to predict the entrepreneurial intention of university students.

(1) Background: Intravesical mitomycin-C (MMC) combined with hyperthermia is increasingly used in non-muscle invasive bladder cancer (NMIBC), especially in the context of a relative BCG shortage. We aim to determine real-world data on the long-term treatment outcomes of adjunct hyperthermic intravesical chemotherapy (HIVEC) with MMC and a COMBAT® bladder recirculation system (BRS); (2) Methods: A prospective observational trial was performed on patients with NMIBC treated with HIVEC using BRS in nine academic institutions in Spain between 2012–2020 (HIVEC-E). Treatment effectiveness (recurrence, progression and overall mortality) was evaluated in patients treated with HIVEC MMC 40mg in the adjuvant setting, with baseline data and a clinical follow-up, that comprise the Full Analysis Set (FAS). Safety, according to the number and severity of adverse effects (AEs), was evaluated in the safety (SAF) population, composed by patients with at least one adjunct HIVEC MMC instillation; (3) Results: The FAS population (n = 502) received a median number of 8.78 ± 3.28 (range 1–20) HIVEC MMC instillations. The median follow-up duration was 24.5 ± 16.5 (range 1–81) months. Its distribution, based on EAU risk stratification, was 297 (59.2%) for intermediate and 205 (40.8%) for high-risk. The figures for five-year recurrence-free and progression-free survival were 50.37% (53.3% for intermediate and 47.14% for high-risk) and 89.83% (94.02% for intermediate and 84.23% for high-risk), respectively. A multivariate analysis identified recurrent tumors (HR 1.83), the duration of adjuvant HIVEC therapy <4 months (HR 1.72) and that high-risk group (HR 1.47) were at an increased risk of recurrence. Independent factors of progression were high-risk (HR 3.89), recurrent tumors (HR 3.32) and the induction of HIVEC therapy without maintenance (HR 2.37). The overall survival was determined by patient age at diagnosis (HR 3.36) and the treatment duration (HR 1.82). The SAF population (n = 592) revealed 406 (68.58%) patients without AEs and 186 (31.42%) with at least one AE: 170 (28.72%) of grade 1–2 and 16 (2.7%) of grade 3–4. The most frequent AEs were dysuria (10%), pain (7.1%), urgency (5.7%), skin rash (4.9%), spasms (3.7%) and hematuria (3.6%); (4) Conclusions: HIVEC using BRS is efficacious and well tolerated. A longer treatment duration, its use in naïve patients and the intermediate-risk disease are independent determinants of success. Furthermore, a monthly maintenance of adjunct MMC HIVEC diminishes the progression rate of NMIBC. [ABSTRACT FROM AUTHOR]

• We have been able to collect demographic, genetic and clinical data of a large series of patients with Pompe disease in Spain. • The estimated prevalence of Pompe disease in Spain is lower than expected and could around 3.1 cases per every millions of habitants. • The region with a higher prevalence of cases is Andalucia, located in the South of Spain. • Our data shows a huge variability in how the diagnosis is obtained and the follow-up is performed across different medical centers in Spain, suggesting that new guidelines are required. Pompe disease is a rare genetic disorder with an estimated prevalence of 1:60.000. The two main phenotypes are Infantile Onset Pompe Disease (IOPD) and Late Onset Pompe Disease (LOPD). There is no published data from Spain regarding the existing number of cases, regional distribution, clinical features or, access and response to the treatment. We created a registry to collect all these data from patients with Pompe in Spain. Here, we report the data of the 122 patients registered including nine IOPD and 113 LOPD patients. There was a high variability in how the diagnosis was obtained and how the follow-up was performed among different centres. Seven IOPD patients were still alive being all treated with enzymatic replacement therapy (ERT) at last visit. Ninety four of the 113 LOPD patients had muscle weakness of which 81 were receiving ERT. We observed a progressive decline in the results of muscle function tests during follow-up. Overall, the Spanish Pompe Registry is a valuable resource for understanding the demographics, patient's journey and clinical characteristics of patients in Spain. Our data supports the development of agreed guidelines to ensure that the care provided to the patients is standardized across the country. [ABSTRACT FROM AUTHOR]

Objective: Alcohol and cannabis consumption in young people aged 14 to 18 years show high and stable prevalence and incidence. The Instituto de Adicciones de Madrid Salud (IAMS) within its prevention strategy aimed at adolescents and young people in Madrid, implements an universal 3-sessions school-based prevention program. To evaluate the effectiveness of a program aimed at alcohol and cannabis from the Theory of Planned Behavior (TPB, Ajzen, 1991), we analysed the changes in consumption and intention of consumption, attitudes and subjective norm as well as in the risk perception., Methods: Quasi-experimental design. Participants: Over 1,529 students belonging to 12 high schools in Madrid (M=15.36 years, DT=1.13, range: 13-18, 51.8% boys) Experimental group: N=790, intervention period October-December 2018. Control group: N=469. The Student's t test was used for the repeated means test. When the difference between the means was significant, the effect size was calculated using Cohen's d index., Results: Alcohol: consumption (t=2.08, p<0.05, d=0.07), intention (t=3.01, p<0.01, d=0.12), risk perception (t=-502, p<0.001, d=0.20), attitudes (t=5.77, p<0.001, d=0.21), subjective norm (t=2.17, p<0.05, d=0.08). Cannabis: intention (t=2.98, p<0.01, d=0.11), risk perception (t=-3.99, p<0.001, d=0.14), attitudes (t=6.19, p<0.001, d=0.23)., Conclusions: Students who received the intervention reduced the favourable attitudes and intention of alcohol and cannabis consumption and alcohol consumption, and increased the risk perception on both substances, with significant differences, but low effect sizes. Related to control group and regarding cannabis there were no significant differences. The program has been shown to be potentially effective, but would benefit from a review for fit to its theoretical framework., Competing Interests: Disclosure The authors report no conflicts of interest in this work.

Coagulopathy is a key feature of COVID-19 and D-dimer has been reported as a predictor of severity. However, because D-dimer test results vary considerably among assays, resolving harmonization issues is fundamental to translate findings into clinical practice. In this retrospective multicenter study (BIOCOVID study), we aimed to analyze the value of harmonized D-dimer levels upon admission for the prediction of in-hospital mortality in COVID-19 patients. All-cause in-hospital mortality was defined as endpoint. For harmonization of D-dimer levels, we designed a model based on the transformation of method-specific regression lines to a reference regression line. The ability of D-dimer for prediction of death was explored by receiver operating characteristic curves analysis and the association with the endpoint by Cox regression analysis. Study population included 2663 patients. In-hospital mortality rate was 14.3%. Harmonized D-dimer upon admission yielded an area under the curve of 0.66, with an optimal cut-off value of 0.945 mg/L FEU. Patients with harmonized D-dimer ≥ 0.945 mg/L FEU had a higher mortality rate (22.4% vs. 9.2%; p < 0.001). D-dimer was an independent predictor of in-hospital mortality, with an adjusted hazard ratio of 1.709. This is the first study in which a harmonization approach was performed to assure comparability of D-dimer levels measured by different assays. Elevated D-dimer levels upon admission were associated with a greater risk of in-hospital mortality among COVID-19 patients, but had limited performance as prognostic test., (© 2021.

Identification of predictors for severe disease progression is key for risk stratification in COVID-19 patients. We aimed to describe the main characteristics and identify the early predictors for severe outcomes among hospitalized patients with COVID-19 in Spain. This was an observational, retrospective cohort study (BIOCOVID-Spain study) including COVID-19 patients admitted to 32 Spanish hospitals. Demographics, comorbidities and laboratory tests were collected. Outcome was in-hospital mortality. For analysis, laboratory tests values were previously adjusted to assure the comparability of results among participants. Cox regression was performed to identify predictors. Study population included 2873 hospitalized COVID-19 patients. Nine variables were independent predictors for in-hospital mortality, including creatinine (Hazard ratio [HR]:1.327; 95% Confidence Interval [CI]: 1.040-1.695, p  = .023), troponin (HR: 2.150; 95% CI: 1.155-4.001; p  = .016), platelet count (HR: 0.994; 95% CI: 0.989-0.998; p  = .004) and C-reactive protein (HR: 1.037; 95% CI: 1.006-1.068; p  = .019). This is the first multicenter study in which an effort was carried out to adjust the results of laboratory tests measured with different methodologies to guarantee their comparability. We reported a comprehensive information about characteristics in a large cohort of hospitalized COVID-19 patients, focusing on the analytical features. Our findings may help to identify patients early at a higher risk for an adverse outcome.

Purpose: Previously, higher circulating levels of matrix metalloproteinase (MMP)-9 and tissue inhibitor matrix metalloproteinases (TIMP)-1 were reported in the first hours after TBI in blood samples from patients with poor prognosis. Thus, the objectives of this study were to determine whether MMP-9 and TIMP-1 levels during the first week of a severe TBI could be used as biomarker predictive of mortality., Methods: We included patients with severe TBI (defined as Glasgow Coma Scale lower than 9), and with Injury Severity Score in non-cranial aspects lower than 9. We determined serum concentrations of MMP-9 and TIMP-1 at days 1, 4 and 8 of TBI., Results: TIMP-1 concentrations at days 1 (p < .001), 4 (p = .001), and 8 (p = .01) of TBI were higher in non-surviving (n = 34) than in surviving (n = 90) patients. ROC curve analyses showed an area under curve of TIMP-1 concentrations at days 1, 4, and 8 of TBI to predict 30-day mortality of 78% (p < .001), 76% (p < .001) and 71% (p = .02) respectively., Conclusions: The most relevant new findings of our study were that TIMP-1 levels during the first week of a severe TBI were higher in non-surviving than in surviving patients and that could be used as biomarker predictive of mortality., (Copyright © 2019 Elsevier Inc.

Objective: Two studies have reported that patients with the 4G/4G genotype of the plasminogen activator inhibitor-1 (PAI-1) genetic polymorphism had higher plasma PAI-1 concentrations and higher risk of death than those with the 4G/5G or 5G/5G genotypes; one study involved 175 children with meningococcal disease, and the other included 88 adult patients with septic shock. Thus, the objective of this study was to determine whether there is an association between carriage of the 4G/4G genotype, plasma PAI-1 concentrations and mortality in a large series of adult septic patients., Methods: An observational, prospective, multicenter study was carried out in six Spanish Intensive Care Units including severe septic patients. We determined the PAI-1 4G/5G polymorphism and plasma PAI-1 concentrations in all patients. The end-points of the study were 30-day and 6-month mortality., Results: We included a total of 260 patients, 82 (31.5%) with 4G/4G, 126 (48.5%) with 4G/5G and 52 (20.0%) with 5G/5G genotype. Multivariate logistic regression analysis showed that the 4G/4G genotype was associated with higher mortality at 30 days (Odds Ratio = 1.95; 95% CI = 1.063-3.561; p = 0.03) and at 6 months (Odds Ratio = 2.19; 95% CI = 1.221-3.934; p = 0.01), and that higher plasma PAI-1 concentrations were associated with higher mortality at 30 days (Odds Ratio = 1.01; 95% CI = 1.002-1.022; p = 0.02) at 6 months (Odds Ratio = 1.01; 95% CI = 1.003-1.023; p = 0.01). Multivariate linear regression analysis showed that increased plasma PAI-1 concentrations were associated with the PAI-1 4G/4G genotype (regression coefficient = 4.82; 95% CI = 3.227 to 6.406; p<0.001)., Conclusions: The major findings of our study, to our knowledge the largest series reporting data about 4G/5G polymorphism of the PAI-1 gene, plasma PAI-1 concentrations and mortality in septic patients, were that septic patients with the 4G/4G genotype had higher plasma PAI-1 concentrations and higher risk of death than those with 4G/5G or 5G/5G genotypes.

Objective: There have been found apoptotic changes in brain tissue samples from animals and humans after a traumatic brain injury (TBI). The protein cytokeratin 18 (CK-18), present in epithelial cells, is cleaved by the action of caspases during apoptosis, and the resulting fragments are released into the blood as caspase-cleaved CK (CCCK)-18. Circulating levels of CCCK-18, as biomarker of apoptosis, have been determined in patients with different processes; however, it has not been explored in TBI patients. Thus, the objective of this study was to determine whether there is an association between serum CCCK-18 levels and mortality and whether such levels could be used as a biomarker to predict outcomes in TBI patients., Methods: A prospective, observational, multicenter study carried out in six Spanish Intensive Care Units. We included patients with severe TBI defined as Glasgow Coma Scale (GCS) lower than 9; and were excluded those patients with Injury Severity Score (ISS) in non-cranial aspects higher than 9. We measured serum CCCK-18 levels at admission. The end-point of the study was 30-day mortality., Results: Surviving patients (n = 73) showed lower serum CCCK-18 levels (P = 0.003) than non-survivors (n = 27). On ROC analysis, the area under the curve (AUC) for serum CCCK-18 levels as predictor of 30-day mortality was 0.69 (95% CI = 0.59-0.78; P = 0.006). We found in survival analysis that patients with serum CCCK-18 higher than 201 u/L had higher 30-day mortality than patients with lower levels (Hazard ratio = 3.9; 95% CI = 1.81-8.34; P<0.001). Regression analyses showed that serum CCCK-18 levels higher than 201 u/L were associated with 30-day mortality (OR = 8.476; 95% CI = 2.087-34.434; P = 0.003) after controlling for age and GCS., Conclusions: The novel finding of our study was that serum CCCK-18 levels are associated with 30-day mortality and could be used as a prognostic biomarker in patients with severe TBI.

Objective: Higher circulating levels of tissue inhibitor of matrix metalloproteinases (TIMP)-1 at the time of severe sepsis diagnosis have been reported in nonsurviving than in surviving patients. However, the following questions remain unanswered: 1) Does TIMP-1/MMP-9 ratio differ throughout the first week of intensive care between surviving and non-surviving patients? 2) Is there an association between TIMP-1/MMP-9 ratio and sepsis severity and mortality during such period? 3) Could TIMP-1/MMP-9 ratio during the first week be used as an early biomarker of sepsis outcome? 4) Is there an association between TIMP-1/MMP-9 ratio and coagulation state and circulating cytokine levels during the first week of intensive care in these patients? The present study sought to answer these questions., Methods: Multicenter, observational and prospective study carried out in six Spanish Intensive Care Units (ICUs) of 295 patients with severe sepsis. Were measured circulating levels of TIMP-1, MMP-9, tumour necrosis factor (TNF)-alpha, interleukin (IL)-10 and plasminogen activator inhibitor (PAI)-1 at day 1, 4 and 8. End-point was 30-day mortality., Results: We found higher TIMP-1/MMP-9 ratio during the first week in non-surviving (n = 98) than in surviving patients (n = 197) (p<0.01). Logistic regression analyses showed that TIMP-1/MMP-9 ratio at days 1, 4 and 8 was associated with mortality. Receiver operating characteristic (ROC) curves showed that TIMP-1/MMP-9 ratio at days 1, 4 and 8 could predict mortality. There was an association between TIMP-1/MMP-9 ratio and TNF-alpha, IL-10, PAI-1 and lactic acid levels, SOFA score and platelet count at days 1, 4 and 8., Conclusions: The novel findings of our study were that non-surviving septic patients showed persistently higher TIMP-1/MMP-9 ratio than survivors ones during the first week, which was associated with severity, coagulation state, circulating cytokine levels and mortality; thus representing a new biomarker of sepsis outcome.

Natalizumab is a monoclonal antibody shown to be highly effective in the treatment of relapsing-remitting multiple sclerosis (RRMS). Patients treated with natalizumab can develop antibodies directed against this agent that may affect the efficacy and safety of the drug. In this observational study, the kinetics of the appearance and the incidence of anti-natalizumab antibodies were followed prospectively for 18 months in a cohort of 64 consecutive patients treated with natalizumab for relapsing MS. Blood samples were drawn immediately before starting natalizumab therapy and each month afterwards. The presence of antibodies against natalizumab was assessed by enzyme-linked immunosorbent assay (ELISA) in all patients. Anti-natalizumab antibodies were detected in nine (14.1%) natalizumab-treated patients, three (4.68%) of whom were transiently positive while six (9.37%) were persistently positive (these patients discontinued natalizumab). All positive titres were observed during the first 4 months of treatment. One patient with a hypersensitivity reaction also had persistent antibodies. We conclude that antibodies against natalizumab develop early, within the first 6 months of therapy with natalizumab. Although no antibodies were detected after 4 months of therapy in this particular study, this does not rule out their development later on in exceptional cases.

The TNF-related apoptosis inducing ligand (TRAIL)/TRAIL receptor system participates in crucial steps in immune cell activation or differentiation. It is able to inhibit proliferation and activation of T cells and to induce apoptosis of neurons and oligodendrocytes, and seems to be implicated in autoimmune diseases. Thus, TRAIL and TRAIL receptor genes are potential candidates for involvement in susceptibility to multiple sclerosis (MS). To test whether single-nucleotide polymorphisms (SNPs) in the human genes encoding TRAIL, TRAILR-1, TRAILR-2, TRAILR-3 and TRAILR-4 are associated with MS susceptibility, we performed a candidate gene case-control study in the Spanish population. 59 SNPs in the TRAIL and TRAIL receptor genes were analysed in 628 MS patients and 660 controls, and validated in an additional cohort of 295 MS patients and 233 controls. Despite none of the SNPs withstood the highly conservative Bonferroni correction, three SNPs showing uncorrected p values<0.05 were successfully replicated: rs4894559 in TRAIL gene, p = 9.8×10(-4), OR = 1.34; rs4872077, in TRAILR-1 gene, p = 0.005, OR = 1.72; and rs1001793 in TRAILR-2 gene, p = 0.012, OR = 0.84. The combination of the alleles G/T/A in these SNPs appears to be associated with a reduced risk of developing MS (p = 2.12×10(-5), OR = 0.59). These results suggest that genes of the TRAIL/TRAIL receptor system exerts a genetic influence on MS.

Background: Pneumocystis colonization in young HIV-infected patients has been poorly studied. The aim of this study was to analyze the prevalence of P jiroveci colonization in a cohort of young HIV-infected patients., Material and Methods: We designed a basal cross-sectional study in 20 young HIV-infected patients to determine the prevalence of P jiroveci colonization in oropharyngeal wash samples studied by nested polymerase chain reaction (PCR). Subsequently, patients were followed up during 50 weeks to observe the development of Pneumocystis pneumonia (PCP)., Results: P jiroveci colonization was detected in eight (40%) of the 20 oropharyngeal wash samples. Genotype 85C/248C was the most frequent. After 50 weeks of follow-up, one colonized patient with advanced immunodepression developed PCP., Conclusions: We have found a high prevalence of P jiroveci colonization in young HIV-infected patients with a major prevalence of genotype 1 (85C/248C). Further studies are necessary to clarify if Pneumocystis colonization could be a potential risk factor of developing PCP in young HIV infected patients., (Copyright © 2011 Society for Adolescent Health and Medicine.

Aims: Illicit cocaine consumption in Spain is one of the highest in Europe. Our objective was to study the incidence of undisclosed cocaine consumption in patients attending in two Spanish Emergency Departments for chest pain., Methods: We analysed urine samples from consenting consecutive patients attending ED for chest pain to determine the presence of cocaine, and other drugs, by semiquantative tests with fluorescence polarization immunoassay (FPIA)., Results: Of 140 cases, 15.7 presented positive test for drugs, and cocaine was present in 6.4%. All cocaine-positive patients were younger (p < 0.001); none was admitted to Hospital (p = 0.08). No significant differences in ED stay or need for hospitalization were found between cocaine-positive and negative patients., Conclusion: This finding in chest pain patients who consented to urine analysis suggests that the true incidence of cocaine use leading to such ED visits may be higher.

Introduction: Matrix metalloproteinases (MMPs) play a role in infectious diseases through extracellular matrix (ECM) degradation, which favors the migration of immune cells from the bloodstream to sites of inflammation. Although higher levels of MMP-9 and tissue inhibitor of matrix metalloproteinases-1 (TIMP-1) have been found in small series of patients with sepsis, MMP-10 levels have not been studied in this setting. The objective of this study was to determine the predictive value of MMP-9, MMP-10, and TIMP-1 on clinical severity and mortality in a large series of patients with severe sepsis., Methods: This was a multicenter, observational, and prospective study carried out in six Spanish Intensive Care Units. We included 192 (125 surviving and 67 nonsurviving) patients with severe sepsis and 50 age- and sex-matched healthy controls in the study. Serum levels of MMP-9, MMP-10, TIMP-1, tumor necrosis factor (TNF)-alpha, and interleukin (IL)-10 were measured in patients with severe sepsis at the time of diagnosis and in healthy controls., Results: Sepsis patients had higher levels of MMP-10 and TIMP-1, higher MMP-10/TIMP-1 ratios, and lower MMP-9/TIMP-1 ratios than did healthy controls (P < 0.001). An association was found between MMP-9, MMP-10, TIMP-1, and MMP-9/TIMP-1 ratios and parameters of sepsis severity, assessed by the SOFA score, the APACHE-II score, lactic acid, platelet count, and markers of coagulopathy. Nonsurviving sepsis patients had lower levels of MMP-9 (P = 0.037), higher levels of TIMP-1 (P < 0.001), lower MMP-9/TIMP-1 ratio (P = 0.003), higher levels of IL-10 (P < 0.001), and lower TNF-alpha/IL-10 ratio than did surviving patients. An association was found between MMP-9, MMP-10, and TIMP-1 levels, and TNF-alpha and IL-10 levels. The risk of death in sepsis patients with TIMP-1 values greater than 531 ng/ml was 80% higher than that in patients with lower values (RR = 1.80; 95% CI = 1.13 to 2.87;P = 0.01; sensitivity = 0.73; specificity = 0.45)., Conclusions: The novel findings of our study on patients with severe sepsis (to our knowledge, the largest series reporting data about MMP levels in sepsis) are that reduced MMP-9/TIMP-1 ratios and increased MMP-10 levels may be of great pathophysiologic significance in terms of severity and mortality, and that TIMP-1 levels may represent a biomarker to predict the clinical outcome of patients with sepsis.

This paper offers a brief biographical sketch of Dr. Luis Cifuentes Delatte (1907-2005) and his professional and educational activities developed in his late years in the Department of Urology at Fundacion Jimenez Diaz (1979-1987), from the perspective, the testimony and particular point of view of the author. In addition, we emphasize the friendship of Dr. Luis Cifuentes with the philosopher Xavier Zubiri (1898-1983) and his cultural links with the intellectual society of his time, his origin and personal trajectory from the Ortega's philosophical-humanist view. In the same way we emphasize Dr. Luis Cifuentes Delatte's contribution to the National Academy of Medicine, where he was member (1972-2005), summarizing his lectures; we also briefly show some of the, unfortunately scarce, autobiographical memories the distinguished urologist published.

Background: The purpose of our study was to assess the effects on infants of protease inhibitor (PI)-based antiretroviral therapy (ART) given to their HIV-positive mothers during pregnancy., Material/methods: A multicenter observational study was carried out at 11 centers in Spain, involving 124 HIV-1-infected pregnant women under ART and their infants. The mothers were classified according to the ART protocols used during pregnancy into two groups: group A, 52 women with > or =2 nucleoside reverse transcriptase inhibitors (NRTI) with or without NNRTI, for a mean time of 4.7+/-2.2 months; and group B, 72 women on protease inhibitor (PI)-based regimens for 5.4+/-2.6 months., Results: Maternal therapy was well tolerated, with no serious adverse effects on pregnancy course. No newborn was infected with HIV-1. There were two deaths at birth (group B), both with extreme prematurity. Among the 126 ART-exposed infants (4 siblings), the most common toxicity was anemia (29%), without significant differences between the two groups. Low birthweight and prematurity were also common (21% and 14%, respectively)., Conclusions: Optimal management of HIV-1 infection in women, regardless of their pregnancy status, can be recommended in more developed countries, without adverse effects on pregnancy outcome, and dramatically decreasing vertical transmission. HAART with PI versus potent ART during pregnancy was effective and safe for infants throughout the 12-month follow-up. In the light of recent advances in anti-HIV-1 pregnancy therapy, the long-term safety of these prophylactic and therapeutical strategies should be studied.

Introduction and Objectives: Before including troponin I detection in the daily practice of our hospital we performed a prospective study to determine its real usefulness and to establish the best cut-off point., Methods: We studied 82 consecutive patients admitted with unstable angina to a community hospital. Troponin I was determined (> 10 h after chest pain). Patients were referred to a tertiary hospital for catheterization/revascularization if clinical events developed., Results: Twenty-five patients (31%) suffered events during admission: recurrent angina in 23 cases (28%); heart failure in 5 (6%); exitus in 3 (4%); myocardial infarction in 1 (1%). The cut-off point for troponin I that best predicted events was 0.1 ng/ml. Patients with troponin I > 0.1 (34 patients, 42%) experienced more events [47 vs. 19%; OR = 3.8 (1.4-10.4); p = 0.01] and had higher rates of recurrent angina (42 vs. 19%), heart failure (12 vs. 2%) and exitus (9 vs 0%). Patients with ECG changes and troponin I > 0.1 showed a significantly higher percentage of events (63%) than those with ECG changes alone (23%) or troponin I > 0.1 alone (15%) or those without ECG changes and troponin I < 0.1 (17%) (p < 0.0001)., Conclusions: Troponin I elevation is useful for predicting in-hospital risk for unstable angina patients admitted to a community hospital. A low cut-off value (0.1 ng/ml) predicts events. The association of ECG changes and high troponin I identifies a population at very high risk; however, the absence of both variables in patients with a diagnosis of unstable angina does not preclude the development of events.
