RESUMO
OBJECTIVE: To analyse compliance with the recommendations on the insertion-maintenance of peripheral venous catheters (PVC) and the incidence of complications according to the healthcare department that inserted the PVCs. PATIENTS AND METHODS: We conducted a prospective cohort follow-up study of PVCs, from their insertion in the emergency or internal medicine (IM) department until their withdrawal. RESULTS: We monitored 590 PVCs, 274 from the emergency department and 316 from IM. In terms of compliance with the process indicators, there was a cannulation rate in the antecubital fossa of 3.5 and 1.6 per 100 catheters-day (P<.001) in the emergency and IM departments, respectively. The sterile placement rates were 1.6 and 12.4 (P<.001), and the rate for transparent dressing was 2.1 and 11.5 (P<.001) per 100 catheters-day in the emergency and IM departments, respectively. The complications rates showed no differences between the departments. The most common complication was phlebitis (95 cases, 16.1%). CONCLUSIONS: Compliance with the insertion-maintenance recommendations for PVC showed differences between the departments; however, the incidence of complications was similar.
RESUMO
BACKGROUND: Several studies show the importance of accurately quantifying not only KRAS and other low-abundant mutations because benefits of anti-EGFR therapies may depend on certain sensitivity thresholds. We assessed whether ultra-selection of patients using a high-sensitive digital PCR (dPCR) to determine KRAS, NRAS, BRAF and PIK3CA status can improve clinical outcomes of panitumumab plus FOLFIRI. PATIENTS AND METHODS: This was a single-arm phase II trial that analysed 38 KRAS, NRAS, BRAF and PIK3CA hotspots in tumour tissues of irinotecan-resistant metastatic colorectal cancer patients who received panitumumab plus FOLFIRI until disease progression or early withdrawal. Mutation profiles were identified by nanofluidic dPCR and correlated with clinical outcomes (ORR, overall response rate; PFS, progression-free survival; OS, overall survival) using cut-offs from 0% to 5%. A quantitative PCR (qPCR) analysis was also performed. RESULTS: Seventy-two evaluable patients were enrolled. RAS (KRAS/NRAS) mutations were detected in 23 (32%) patients and RAS/BRAF mutations in 25 (35%) by dPCR, while they were detected in 7 (10%) and 11 (15%) patients, respectively, by qPCR. PIK3CA mutations were not considered in the analyses as they were only detected in 2 (3%) patients by dPCR and in 1 (1%) patient by qPCR. The use of different dPCR cut-offs for RAS (KRAS/NRAS) and RAS/BRAF analyses translated into differential clinical outcomes. The highest ORR, PFS and OS in wild-type patients with their lowest values in patients with mutations were achieved with a 5% cut-off. We observed similar outcomes in RAS/BRAF wild-type and mutant patients defined by qPCR. CONCLUSIONS: High-sensitive dPCR accurately identified patients with KRAS, NRAS, BRAF and PIK3CA mutations. The optimal RAS/BRAF mutational cut-off for outcome prediction is 5%, which explains that the predictive performance of qPCR was not improved by dPCR. The biological and clinical implications of low-frequent mutated alleles warrant further investigations. CLINICALTRIALS.GOV NUMBER: NCT01704703. EUDRACT NUMBER: 2012-001955-38.

BACKGROUND: Circulating tumor DNA (ctDNA) is a potential source for tumor genome analysis. We explored the concordance between the mutational status of RAS in tumor tissue and ctDNA in metastatic colorectal cancer (mCRC) patients to establish eligibility for anti-epidermal growth factor receptor (EGFR) therapy. PATIENTS AND METHODS: A prospective-retrospective cohort study was carried out. Tumor tissue from 146 mCRC patients was tested for RAS status with standard of care (SoC) PCR techniques, and Digital PCR (BEAMing) was used both in plasma and tumor tissue. RESULTS: ctDNA BEAMing RAS testing showed 89.7% agreement with SoC (Kappa index 0.80; 95% CI 0.71 - 0.90) and BEAMing in tissue showed 90.9% agreement with SoC (Kappa index 0.83; 95% CI 0.74 - 0.92). Fifteen cases (10.3%) showed discordant tissue-plasma results. ctDNA analysis identified nine cases of low frequency RAS mutations that were not detected in tissue, possibly due to technical sensitivity or heterogeneity. In six cases, RAS mutations were not detected in plasma, potentially explained by low tumor burden or ctDNA shedding. Prediction of treatment benefit in patients receiving anti-EGFR plus irinotecan in second- or third-line was equivalent if tested with SoC PCR and ctDNA. Forty-eight percent of the patients showed mutant allele fractions in plasma below 1%. CONCLUSIONS: Plasma RAS determination showed high overall agreement and captured a mCRC population responsive to anti-EGFR therapy with the same predictive level as SoC tissue testing. The feasibility and practicality of ctDNA analysis may translate into an alternative tool for anti-EGFR treatment selection.

This study analyzed the time course of recovery following 2 resistance exercise protocols differing in level of effort: maximum (to failure) vs. half-maximum number of repetitions per set. 9 males performed 3 sets of 4 vs. 8 repetitions with their 80% 1RM load, 3×4(8) vs. 3×8(8), in the bench press and squat. Several time-points from 24 h pre- to 48 h post-exercise were established to assess the mechanical (countermovement jump height, CMJ; velocity against the 1 m·s(-1) load, V1-load), biochemical (testosterone, cortisol, GH, prolactin, IGF-1, CK) and heart rate variability (HRV) and complexity (HRC) response to exercise. 3×8(8) resulted in greater neuromuscular fatigue (higher reductions in repetition velocity and velocity against V1-load) than 3×4(8). CMJ remained reduced up to 48 h post-exercise following 3×8(8), whereas it was recovered after 6 h for 3×4(8). Significantly greater prolactin and IGF-1 levels were found for 3×8(8) vs. 3×4(8). Significant reductions in HRV and HRC were observed for 3×8(8) vs. 3×4(8) in the immediate recovery. Performing a half-maximum number of repetitions per set resulted in: 1) a stimulus of faster mean repetition velocities; 2) lower impairment of neuromuscular performance and faster recovery; 3) reduced hormonal response and muscle damage; and 4) lower reduction in HRV and HRC following exercise.

OBJECTIVE: To assess the psychometric properties of the behavioral indicators of pain scale (ESCID) when applied to a wide range of medical and surgical critical patients. DESIGN: A multicentre, prospective observational study was designed to validate a scale measuring instrument. SETTING: Twenty Intensive Care Units of 14 hospitals belonging to the Spanish National Health System. PARTICIPANTS: A total of 286 mechanically ventilated, unable to self-report critically ill medical and surgical adult patients. PROCEDURE: Pain levels were measured by two independent evaluators simultaneously, using two scales: ESCID and the behavioral pain scale (BPS). Pain was observed before, during, and after two painful procedures (turning, tracheal suctioning) and one non-painful procedure. MAIN VARIABLES: ESCID reliability was measured on the basis of internal consistency using the Cronbach-α coefficient. Inter-rater and intra-rater agreement were measured. The Spearman correlation coefficient was used to assess the correlation between ESCID and BPS. RESULTS: A total of 4386 observations were made in 286 patients (62% medical and 38% surgical). High correlation was found between ESCID and BPS (r=0.94-0.99; p<0.001), together with high intra-rater and inter-rater concordance. ESCID was internally reliable, with a Cronbach-α value of 0.85 (95%CI 0.81-0.88). Cronbach-α coefficients for ESCID domains were high: facial expression 0.87 (95%CI 0.84-0.89), calmness 0.84 (95%CI 0.81-0.87), muscle tone 0.80 (95%CI 0.75-0.84), compliance with mechanical ventilation 0.70 (95%CI 0.63-0.75) and consolability 0.85 (95%CI 0.81-0.88). CONCLUSION: ESCID is valid and reliable for measuring pain in mechanically ventilated unable to self-report medical and surgical critical care patients. CLINICALTRIALS.GOV: NCT01744717.

OBJECTIVE: To assess pain response on patients with moderate to severe head injury before a common nursing procedure: tracheal suctioning. MATERIAL AND METHOD: An observational longitudinal pilot study with consecutive sampling performed from September to December of 2012. Pain was assessed by a pain behavioral indicator scale 5 minutes before, meanwhile and 15 minutes after tracheal suctioning the days 1, 3 and 6 of their intensive care unit (ICU) stay, as well as a non-painful procedure: rubbing with gauze the forearm of the patient. Pseudo-analgesia and hemodynamic variables were also recorded. Descriptive analysis of the variables, inferential statistics with t-student and Anova with SPSS 17.0; statistical tests were considered significant if the critical level observed was less than 5% (P<.05). RESULTS: Pain was assessed on 27 patients. 82% suffered from severe head trauma and 18% moderate. The average pain value during nursing procedure day 1 was 3, 18±2.6, day 3: 2, 59±2 and day 6: 3, 94±2.3. There was a significant increase in mean pain while performing suctioning during the three days of assessment (P<.05); however no significant differences between the average pain value on the three days of the assessment (P>.05) were shown. Data for the painless procedure were significantly different on day 6 (P<.05) CONCLUSION: During tracheal suctioning in patients with head injury in the first 6 days in the ICU, objective mild-moderate pain according to ESCID scale has been detected.

OBJECTIVES: To evaluate the incidence and risk factors of constipation in patients with severe trauma (ST). MATERIALS AND METHOD: A retrospective observational study (January-December 2011) of medical records in ST-patients with a minimum stay of 5 days was performed. Descriptive analysis of variables, inferential analysis: Student's T test and Chi-square of SPSS 17.0. Significance level P<.05. RESULTS: A total of 80 patients fulfilled the inclusion criteria, but only 69 could be analyzed. Of these, 84.06% showed constipation (according to its definition by the Work Group for Metabolism and Nutrition SEMICYUC). The most frequent day of first stool was day 7 and 9 after tolerance of enteral nutrition. Statistical significance (S.S.) of constipation was found with stay, days of sedation/relaxation/opiates, and mechanical ventilation. There was no S.S. between early enteral nutrition (EEN) and constipation (P>.05). CONCLUSIONS: There is a very high incidence of constipation in ST patients. ICU stay, days of analgesic sedation, relaxation, and mechanical ventilation are risk factors that influence the occurrence of this problem. Laxatives should be prescribed prophylactically.

AIMS: Quantifying and evaluating the response to the bedside monitor alarms (BMA) by nurses in intensive care unit (ICU). METODOLOGY: Prospective observational study (October 2011-January 2012). Randomized blind audit on alarm management. Alarm programming and alarm limits were related to experience in ICU. We evaluated the response to BMA with the variables: alarm type (relevant/not relevant/alert) and response type. Descriptive analysis of variables for multivariate ANOVA and Chi-square test with SPSS 17.0. RESULTS: 434 audits were analyzed. The programming was: Blood pressure (BP) 88.25%, heart rate (HR) 98.62% O(2) saturation (SO) 96.79%, respiratory rate (FR) 65.75%. The alarms originated were BP 49.73%, 10.75% HR, 39.25% SO, 3.27% FS. The nurse responded to 93.3% of them and 50% were treated before 10 sec. 56.16% of the alarms were not relevant, 25.12% relevant and 18.72% alerting. 41.8% were due to handling. CONCLUSION: The alarms are programmed/attended by the nurse and there is uniformity in programming/selection limits. 25% of BMA carried therapeutic attitude.

Appropriateness is a dimension of quality that evaluates the effective use of technologies, resources or interventions in specific situations or populations, assessing whether our interventions do more benefit than harm. The evidence regarding pain monitoring in the critically ill patient points to the periodic assessment of pain using appropriate tools, with the aim of improving pain management and more efficient use of analgesics in the intensive care unit. The first step would be to assess the patient's ability to communicate or self-report and, based on this, to select the most appropriate pain assessment tool. In patients who are unable to self-report, behavioural pain assessment tools are recommended. When we talk about the suitability of behavioural scales for pain monitoring in critically ill patients unable to self-report, we refer to their use with a clear clinical benefit, i.e. using the right tool for pain assessment to be effective, efficient and consistent with bioethical principles. To our knowledge, there are no published data on the suitability of pain assessment tools in unable to self-report critically ill patients, so, in the framework of continuous quality improvement in pain care, new research should incorporate this approach by integrating the best scientific evidence with current clinical practice.

OBJECTIVE: To assess pain in non-communicative patients with severe trauma undergoing mechanical ventilation prior to, during and after tracheal suctioning, mobilization and wound care. MATERIAL AND METHOD: A prospective and observational study from October to December 2011 was performed. Study variables were ESCID scale and monitoring of vital signs (blood pressure, heart rate, and respiratory rate). Data were gathering 5 minutes before, during and 15 minutes after the 3 procedures. The nursing evolutive report recorded pain assessment, administration and effectiveness of the analgesia. Descriptive analysis of variables included Student's T test/ANOVA for multivariate analysis with SPSS 17.0. RESULTS: A hundred eighty four observations: 46.8% tracheal suctioning, 38.5% mobilization and 14.7% wound care were performed in 29 patients. ESCID score was 0.4±1 before, 3.4±2.7 during and 0.4±1 after for wound care; 0.4±1.1 before, 3.6±2.2 during and 1.1±0.5 for tracheal suctioning; 0.5±1.1 before, 3±2.8 during and 0.2±0.8 after for mobilization. These increased significantly during the performance of the 3 procedures before-during/during-after: P=.000. All the hemodynamic variables were significantly modified during mobilization and tracheal suctioning: before-during/during-after: P=.000, with the exception of the cures that only affected respiratory rate. 27% of the procedures received analgesia: 9% received it before, 15% during and 3.2% after, with more analgesia being required for the wound care (33.3%). The data collected in the nursing report on the evaluation of pain/effectiveness of the analgesia showed 20.66%. CONCLUSION: An increase on the ESCID score was observed while performing the procedures.

INTRODUCTION: Bibliometric analysis allow the quantitative evaluation of the characteristics of a scientific publication. OBJECTIVE: To perform a bibliometric analysis of original articles in the journal Enfermería Intensiva from 2001 to 2020. RESULTS: The journal Enfermería Intensiva has published, between 2001 and 2020, 438 works, of which 259 are original articles (59.1%). These original articles are mostly quantitative studies (76.1%), with an average of 30.5 bibliographic references (SD 13.9), 4.9 citations (SD 1.7) in the Web of Science and Scopus repertoires, and 15,489.5 visits/downloads (median 9090 and interquartile range 4567-15,260) according to information on the magazine's website. These originals have been signed by 1345 authors, which represents a collaboration index of 5.2. 78.0% of the authors are sporadic, having published only one work. Most of the articles come from authors who work in institutionally located in hospitals and university centers, and geographically in the Communities of Madrid, Cataluña, Navarra and Andalucía. CONCLUSIONS: There is little international, regional and institutional collaboration, producing the highest level of collaboration between authors from the same center. The journal has established itself in the panorama of scientific nursing research in Spain and shows bibliometric indicators similar or even superior to other publications in its environment.

BACKGROUND: Alzheimer's disease (AD) prevention trials require a large outreach and screening funnel to identify cognitively unimpaired adults who meet the study's inclusion criteria, such as certain clinical or demographic criteria, genetic risk factors, and/or biomarker evidence of the disease. OBJECTIVES: Describe tactics and strategies to identify and enroll cognitively unimpaired adults with one (heterozygotes [HT]) or two (homozygotes [HM]) copies of the APOE ε4 allele, a genetic risk factor for dementia due to AD, into the Alzheimer's Prevention Initiative (API) Generation Program, the largest and only prevention trials for late onset AD using this enrichment technique. DESIGN AND SETTING: The Generation Program was comprised of two global, randomized, double-blind, placebo-controlled, parallel group adaptive design with variable treatment duration clinical trials. Generation Study 1 randomized participants into one of two cohorts: Cohort 1 which evaluated CAD106 vs. placebo or Cohort 2 which evaluated umibecestat vs placebo. Generation Study 2 randomized participants into two doses of umibecestat vs. placebo. The Generation Program was terminated early in 2019, while enrollment was still occurring. PARTICIPANTS: Both Generation Study 1 and Generation Study 2 enrolled cognitively unimpaired APOE ε4 HMs aged 60-75; Generation Study 2 also enrolled APOE ε4 HTs ages 60-75 with elevated brain amyloid. METHODS AND MEASUREMENTS: Describe results of the centralized and localized outreach, recruitment, screening strategies and tactics as well as characteristics of sites successful at enrolling genetically eligible participants, with a particular focus on APOE ε4 HMs given the 2-3% prevalence of this genotype. RESULTS: At the time the trial program was terminated, 35,333 individuals had consented to the optional prescreening ICF1a/ICFA and provided a sample of DNA for APOE genotyping, 1,138 APOE ε4 HMs consented to screening for Generation Study 1 (ICF1b), and 1,626 APOE ε4 carriers were randomized into either Generation Study 1 or Generation Study 2. Genetic testing registries, partnerships with genetic testing/counseling companies, and the optional prescreening ICF1a/ICFA were the most successful strategies for identifying genetically eligible participants for screening. CONCLUSIONS: It is feasible to recruit, screen and randomize cognitively unimpaired APOE ε4 carriers, particularly APOE ε4 HMs for a global AD prevention trial. The Generation Program was on track to complete enrollment by end of 2019. Factors that were key to this success included: working with sites to develop customizable outreach, recruitment, and screening programs specific to their site needs, providing forums for sites to exchange best practices, and developing partnerships between the sponsor team and trial sites.

At present, there is great concern about limited water resources and water quality, which require a more advanced technology. The Moving Bed Biofilm Reactor (MBBR) has been shown to be an efficient technology for removal of organic matter and nutrients in industrial and urban wastewater treatment. However, there are some pollutants which are more difficult to remove by biological processes, so this process can be improved with additional physical and chemical treatments such as electrocoagulation, which appears to be a promising technology in electrochemical treatments. In this research, urban wastewater was treated in an MBBR plant with an electrocoagulation pre-treatment. K1 from AnoxKaldnes and AQWISE ABC5 from Aqwise were the carriers studied under three different filling ratios (20, 35, and 50%). The experimental pilot plant had four bioreactors with 20 L of operation volume and a common feed tank with 100 L of operation volume. The movement of the carriers was generated by aeration and stirrer systems. Organic matter removal was studied by analysis of soluble chemical oxygen demand (sCOD). The maximum organic matter removal in this MBBR system was 65.8% ± 1.4% and 78.4% ± 0.1% for K1 and Aqwise ABC5 carriers, respectively. Moreover, the bacterial diversity of the biofilm was studied by temperature-gradient gel electrophoresis (TGGE) of PCR-amplified partial 16S rRNA genes. 20 prominent TGGE bands were successfully reamplified and sequenced, being the predominant population: ß-Proteobacteria, α-Proteobacteria, and Actinobacteria.

Septo-optic dysplasia (SOD) is a rare congenital condition of unknown cause, with a characteristic triad that includes optic nerve hypoplasia, pituitary function abnormalities and midline brain defects, in addition to a broad spectrum of symptoms and associations. A total of five clinical cases are presented, four of which met the complete classic triad. All of them showed a wide variety of ophthalmological, endocrinological and neurological alterations. Within the ophthalmological spectrum of SOD, papillary hypoplasia and ocular motility alterations (nystagmus, strabismus) stand out. Other less frequent ones may also appear, such as pupillary alterations, microphthalmia and coloboma. Given the suspicion of SOD, brain MRI scan should be performed, as well as consultation with the paediatric department in order to complete the study and indicate, if necessary, systemic treatment.

Medical history of 6 patients diagnosed with Williams-Beuren Syndrome (SWB) in pediatric age was revised. All the patients presented characteristic elf facies and cardiovascular abnormalities. All presented good visual acuity, except one case of unilateral amblyopia. The most frequent refractive error was hyperopia (nâ¯=â¯6; 100%) and astigmatism (nâ¯=â¯5; 83.3%). Ocular motility alterations were found in 2 patients (1 case of exophoria with hyperfunction of right inferior oblique and another of congenital endotropia with bilateral hyperfunction of inferior oblique). On the cognitive function, 66.7% (nâ¯=â¯4) had visoperceptive disorders. Other findings were epicanthus (nâ¯=â¯6; 100%) and congenital obstruction of the nasolacrimal duct with unilateral epiphora (nâ¯=â¯1; 16.7%). SWB is a rare disorder with complex ophthalmological and systemic manifestations. For this reason, ophthalmological follow-up of these children is recommended.

INTRODUCTION: Premature children birth and survival is becoming more frequent due to the improvement in obstetric and neonatal care. This makes it increasingly common to find patients with history of preterm birth in ophthalmology clinics, both in pediatric and adult ages. Premature birth can lead to ocular structural changes, being possible to affect the ganglion cell complex (GCC), among other structures, which can be studied using optical coherence tomography. MATERIALS AND METHODS: To carry out a bibliographic review of the studies that analyze GCC in patients with a history of prematurity compared with patients born at term. RESULTS: Several studies that analyze GCC in patients with a history of prematurity are referenced and their results are studied. CONCLUSIONS: In our clinical practice, knowing the history of prematurity is fundamental in the assessment of GCC measured by optical coherence tomography, since this layer is different in the patients with a history of prematurity compared to patients born at term.
RESUMO
OBJECTIVE: To analyse compliance with the recommendations on the insertion-maintenance of peripheral venous catheter (PVC) and the incidence of complications according to the healthcare department that inserted the PVCs. PATIENTS AND METHODS: We conducted a prospective cohort follow-up study of PVCs, from their insertion in the emergency or internal medicine (IM) department until their withdrawal. RESULTS: We monitored 590 PVCs, 274 from the emergency department and 316 from IM. In terms of compliance with the process indicators, there was a cannulation rate in the antecubital fossa of 3.5 and 1.6 per 100 catheters-day (pâ¯<â¯.001) in the emergency and IM departments, respectively. The sterile placement rates were 1.6 and 12.4 (pâ¯<â¯.001), and the rate for transparent dressing was 2.1 and 11.5 (pâ¯<â¯.001) per 100 catheters-day in the emergency and IM departments, respectively. The complications rates showed no differences between the departments. The most common complication was phlebitis (95 cases, 16.1%). CONCLUSIONS: Compliance with the insertion-maintenance recommendations for PVC showed differences between the departments; however, the incidence of complications was similar.

INTRODUCTION: There is a growing interest in the study of the relationship between heart disease, including acute coronary syndrome (ACS) and cognitive impairment, and although the factors mediating ACS and cognitive impairment are not well understood, the debate revolves around the role of the left ventricular ejection fraction (LVEF). AIMS: To determine the presence of cognitive impairment in patients with ACS and explore its association with various factors, including sociodemographic, medication use and performance on cardiac function tests (in particular LVEF). PATIENTS AND METHODS: Sociodemographic, medical and neuropsychological variables were collected in 80 patients with ACS participating in a cardiac rehabilitation programme. Their scores on the neuropsychological battery were compared with normative population data to determine which subjects showed deficient performance. Regression analyses were conducted to determine which factors are associated with performance on neuropsychological tests. RESULTS: Compared to their normative group, 37.5% of the subjects had low scores on three or more neuropsychological tests. Age, low educational level and low LVEF explained up to 51% of the variability in neuropsychological test results. CONCLUSIONS: Patients with ACS are more likely to have impaired cognitive functions, such as attention, memory and executive functions, along with a slower information processing speed. An LVEF below 50% could be a major explanatory factor for such cognitive impairment.
TITLE: Variabilidad en el rendimiento neuropsicológico en pacientes con síndrome coronario agudo.Introducción. Existe un interés creciente por el estudio de la relación entre las cardiopatías, incluido el síndrome coronario agudo (SCA) y el deterioro cognitivo, y, aunque no se conocen con concreción los factores que median entre el SCA y el deterioro cognitivo, en el centro de este debate se encuentra el papel de la fracción de eyección del ventrículo izquierdo (FEVI). Objetivos. Determinar la presencia de deterioro cognitivo en pacientes con SCA y explorar su asociación con diversos factores sociodemográficos, consumo de fármacos, rendimiento en pruebas funcionales cardíacas (en particular, la FEVI). Pacientes y métodos. Se recogieron variables sociodemográficas, médicas y neuropsicológicas en 80 pacientes con SCA que participaban en un programa de rehabilitación cardíaca. Se compararon sus puntuaciones en la batería neuropsicológica con los datos normativos poblacionales para determinar qué sujetos mostraban un rendimiento deficitario. Se realizaron análisis de regresión para determinar qué factores se asocian con el rendimiento en las pruebas neuropsicológicas. Resultados. En comparación con su grupo normativo, el 37,5% de los sujetos presentó una baja puntuación en tres o más test neuropsicológicos. La edad, un bajo nivel educativo y una FEVI baja explicaron hasta el 51% de la variabilidad en los resultados de las pruebas neuropsicológicas. Conclusiones. Los pacientes con SCA tienen más posibilidades de presentar un deterioro de funciones cognitivas, como la atención, la memoria y las funciones ejecutivas, junto con un enlentecimiento en la velocidad de procesamiento de la información. Una FEVI inferior al 50% podría ser un factor explicativo destacado de dicho deterioro cognitivo.

OBJECTIVE: To analyze diagnostic (blood drawings) and iatrogenic (Continuous Renal Replacement Therapy, CRRT) blood losses (BL) in severe trauma patients. METHOD: A one-year descriptive, prospective and observational study. We included patients over 15 years of age, admitted with severe trauma and who had a score of > or =16 on the Injury Severity Index (ISS). Those patients in whom limitation of therapeutic effort had been indicated were excluded. A total of 225 patients with 1619 days of evolution were analyzed for volume of BL/day/patient, type of diagnostic test, clinical outcome and utilization of CRRT. The variables were described as mean +/- standard deviation with the Student's T test. RESULTS: Average blood loss of patient per day was 55.5+/-32.2 cc. Statistically significant differences were found between the blood volume drawn when the first day was compared to the second day, 73.5+/-32.2 vs. 56.3+/-21.9 (p<0.001); clinical outcome (alive vs death) 54.8+/-33 vs. 60.7+/-24.9 (p<0.05); severity (ISS<31 or > or =31) 54.65+/-20 vs. 61.5+/-28.5 (p<0.001), No RRT vs RRT: 50.9+/-18.9 vs. 97.2+/-72.6 (p<0.001). CONCLUSIONS: The greatest diagnostic BL occurs during the resuscitation phase, in the patients who die, in those with greater severity and those undergoing CRRT.

Chondrosarcoma is a malignant tumor which often affects the pelvic ring and its symptomathology is non-specific and insidious. We display a case of a right iliopubic branch chondrosarcoma in a 62-year-old male whose first sing was a four-year history of sporadic macroscopic haematuria, related to efforts. After being studied by the Urology Department by cystoscopy and biopsy of bladder tumor, chondral cells were appreciated. Further study with imaging tests diagnosed low-grade chondrosarcoma with bladder infringement. The case is assessed by Musculoskeletal Tumors Committee and a multidisciplinary approach is carried out through en bloc resection and pelvic floor reconstruction. Currently the patient remains asymptomatic.
El condrosarcoma es un tumor maligno que afecta con frecuencia la pelvis y su sintomatología es inespecífica e insidiosa. Describimos el caso de un condrosarcoma de la rama iliopubiana derecha en un varón de 62 años cuyo primer signo de aparición fue una hematuria macroscópica esporádica, relacionada con esfuerzos y de cuatro meses de evolución. Tras ser estudiado por el servicio de urología mediante cistoscopía con biopsia de tumoración en pared vesical se aprecian células de estirpe condral. Tras posterior estudio con pruebas de imagen se diagnostica condrosarcoma de bajo grado con invasión de la vejiga, por lo que es valorado en el comité de tumores musculoesqueléticos y se realiza un abordaje multidisciplinar mediante exéresis en bloque y reconstrucción del suelo pélvico. Actualmente el paciente continúa asintomático.
