A European-Japanese study on peach allergy: IgE to Pru p 7 associates with severity.

BACKGROUND: Pru p 3 and Pru p 7 have been implicated as risk factors for severe peach allergy. This study aimed to establish sensitization patterns to five peach components across Europe and in Japan, to explore their relation to pollen and foods and to predict symptom severity. METHODS: In twelve European (EuroPrevall project) and one Japanese outpatient clinic, a standardized clinical evaluation was conducted in 1231 patients who reported symptoms to peach and/or were sensitized to peach. Specific IgE against Pru p 1, 2, 3, 4 and 7 and against Cup s 7 was measured in 474 of them. Univariable and multivariable Lasso regression was applied to identify combinations of parameters predicting severity. RESULTS: Sensitization to Pru p 3 dominated in Southern Europe but was also quite common in Northern and Central Europe. Sensitization to Pru p 7 was low and variable in the European centers but very dominant in Japan. Severity could be predicted by a model combining age of onset of peach allergy, probable mugwort, Parietaria pollen and latex allergy, and sensitization to Japanese cedar pollen, Pru p 4 and Pru p 7 which resulted in an AUC of 0.73 (95% CI 0.73-0.74). Pru p 3 tended to be a risk factor in South Europe only. CONCLUSIONS: Pru p 7 was confirmed as a significant risk factor for severe peach allergy in Europe and Japan. Combining outcomes from clinical and demographic background with serology resulted in a model that could better predict severity than CRD alone.

Component-resolved diagnosis and beyond: Multivariable regression models to predict severity of hazelnut allergy.

BACKGROUND: Component-resolved diagnosis (CRD) has revealed significant associations between IgE against individual allergens and severity of hazelnut allergy. Less attention has been given to combining them with clinical factors in predicting severity. AIM: To analyze associations between severity and sensitization patterns, patient characteristics and clinical history, and to develop models to improve predictive accuracy. METHODS: Patients reporting hazelnut allergy (n = 423) from 12 European cities were tested for IgE against individual hazelnut allergens. Symptoms (reported and during Double-blind placebo-controlled food challenge [DBPCFC]) were categorized in mild, moderate, and severe. Multiple regression models to predict severity were generated from clinical factors and sensitization patterns (CRD- and extract-based). Odds ratios (ORs) and areas under receiver-operating characteristic (ROC) curves (AUCs) were used to evaluate their predictive value. RESULTS: Cor a 9 and 14 were positively (OR 10.5 and 10.1, respectively), and Cor a 1 negatively (OR 0.14) associated with severe symptoms during DBPCFC, with AUCs of 0.70-073. Combining Cor a 1 and 9 improved this to 0.76. A model using a combination of atopic dermatitis (risk), pollen allergy (protection), IgE against Cor a 14 (risk) and walnut (risk) increased the AUC to 0.91. At 92% sensitivity, the specificity was 76.3%, and the positive and negative predictive values 62.2% and 95.7%, respectively. For reported symptoms, associations and generated models proved to be almost identical but weaker. CONCLUSION: A model combining CRD with clinical background and extract-based serology is superior to CRD alone in assessing the risk of severe reactions to hazelnut, particular in ruling out severe reactions.

Effect of goal-directed haemodynamic therapy on postoperative complications in low-moderate risk surgical patients: a multicentre randomised controlled trial (FEDORA trial).

BACKGROUND: The aim of this study was to evaluate postoperative complications in patients having major elective surgery using oesophageal Doppler monitor-guided goal-directed haemodynamic therapy (GDHT), in which administration of fluids, inotropes, and vasopressors was guided by stroke volume, mean arterial pressure, and cardiac index. METHODS: The FEDORA trial was a prospective, multicentre, randomised, parallel-group, controlled patient- and observer-blind trial conducted in adults scheduled for major elective surgery. Randomization and allocation were carried out by a central computer system. In the control group, intraoperative fluids were given based on traditional principles. In the GDHT group, the intraoperative goals were to maintain a maximal stroke volume, with mean arterial pressure >70 mm Hg, and cardiac index ≥2.5 litres min-1 m-2. The primary outcome was percentage of patients with moderate or severe postoperative complications during the first 180 days after surgery. RESULTS: In total, 450 patients were randomized to the GDHT group (n=224) or control group (n=226). Data from 420 subjects were analysed. There were significantly fewer with complications in the GDHT group (8.6% vs 16.6%, P=0.018). There were also fewer complications (acute kidney disease, pulmonary oedema, respiratory distress syndrome, wound infections, etc.), and length of hospital stay was shorter in the GDHT group. There was no significant difference in mortality between groups. CONCLUSIONS: Oesophageal Doppler monitor-guided GDHT reduced postoperative complications and hospital length of stay in low-moderate risk patients undergoing intermediate risk surgery, with no difference in mortality at 180 days. CLINICAL TRIAL REGISTRATION: ISRCTN93543537.

PET-CT in presurgical lymph node staging in non-small cell lung cancer: the importance of false-negative and false-positive findings. / La PET-TC en la estadificación ganglionar prequirúrgica del carcinoma de pulmón de células no pequeñas: implicación de los falsos negativos y falsos positivos.

OBJECTIVE: To assess the importance of false-negative and false-positive findings in computed tomography (CT) and 18F-FDG positron emission tomography (PET) in mediastinal lymph node staging in patients undergoing surgery for non-small cell lung cancer (NSCLC). MATERIAL AND METHODS: This retrospective study included 113 consecutive patients and 120 resected NSCLCs; 22 patients received neoadjuvant treatment. We compared the findings on preoperative 18F-FDG PET-CT studies with the postoperative pathology findings. Lymph node size and primary tumor size were measured with CT, and lymph nodes and primary tumors were evaluated qualitatively and semiquantitatively (using standardized uptake values (SUVmax)) with PET. RESULTS: Metastatic lymph nodes were found in 26 (21.7%) of the 120 tumors and in 41 (7.7%) of the 528 lymph node stations analyzed. 18F-FDG PET-CT yielded 53.8% sensitivity, 76.6% specificity, 38.9% positive predictive value, 85.7% negative predictive value, and 71.7% diagnostic accuracy. The false-negative rate was 14.2%. Multivariable analysis found that the factors associated with false-negative findings were a moderate degree of differentiation in the primary tumor (p = 0.005) and an SUVmax of the primary tumor >4 (p = 0.027). The false-positive rate was 61.1%, and the multivariable analysis found that lymph node size >1cm was associated with false-positive findings (p < 0.001). CONCLUSIONS: In mediastinal lymph node staging in patients with NSCLC, 18F-FDG PET-CT improves the specificity and negative predictive value and helps clinicians to select the patients that will benefit from surgery. Given the high rate of false positives, histological confirmation of positive cases is recommendable.

The EuroPrevall outpatient clinic study on food allergy: background and methodology.

BACKGROUND: The EuroPrevall project aimed to develop effective management strategies in food allergy through a suite of interconnected studies and a multidisciplinary integrated approach. To address some of the gaps in food allergy diagnosis, allergen risk management and socio-economic impact and to complement the EuroPrevall population-based surveys, a cross-sectional study in 12 outpatient clinics across Europe was conducted. We describe the study protocol. METHODS: Patients referred for immediate food adverse reactions underwent a consistent and standardized allergy work-up that comprised collection of medical history; assessment of sensitization to 24 foods, 14 inhalant allergens and 55 allergenic molecules; and confirmation of clinical reactivity and food thresholds by standardized double-blind placebo-controlled food challenges (DBPCFCs) to milk, egg, fish, shrimp, peanut, hazelnut, celeriac, apple and peach. RESULTS: A standardized methodology for a comprehensive evaluation of food allergy was developed and implemented in 12 outpatient clinics across Europe. A total of 2121 patients (22.6% <14 years) reporting 8257 reactions to foods were studied, and 516 DBPCFCs were performed. CONCLUSIONS: This is the largest multicentre European case series in food allergy, in which subjects underwent a comprehensive, uniform and standardized evaluation including DBPCFC, by a methodology which is made available for further studies in food allergy. The analysis of this population will provide information on the different phenotypes of food allergy across Europe, will allow to validate novel in vitro diagnostic tests, to establish threshold values for major allergenic foods and to analyse the socio-economic impact of food allergy.

A systematic review of sugammadex vs neostigmine for reversal of neuromuscular blockade.

We reviewed systematically sugammadex vs neostigmine for reversing neuromuscular blockade. We included 17 randomised controlled trials with 1553 participants. Sugammadex reduced all signs of residual postoperative paralysis, relative risk (95% CI) 0.46 (0.29-0.71), p = 0.0004 and minor respiratory events, relative risk (95% CI) 0.51 (0.32-0.80), p = 0.0034. There was no difference in critical respiratory events, relative risk (95% CI) 0.13 (0.02-1.06), p = 0.06. Sugammadex reduced drug-related side-effects, relative risk (95% CI) 0.72 (0.54-0.95), p = 0.02. There was no difference in the rate of postoperative nausea or the rate of postoperative vomiting, relative risk (95% CI) 0.94 (0.79-1.13), p = 0.53, and 0.87 (0.65-1.17), p = 0.36 respectively.

The prevalence and distribution of food sensitization in European adults.

BACKGROUND: Complaints of 'food allergy' are increasing. Standardized surveys of IgE sensitization to foods are still uncommon and multicountry surveys are rare. We have assessed IgE sensitization to food-associated allergens in different regions of Europe using a common protocol. METHODS: Participants from general populations aged 20-54 years in eight European centres (Zurich, Madrid, Utrecht, Lodz, Sophia, Athens, Reykjavik and Vilnius) were asked whether they had allergic symptoms associated with specific foods. Weighted samples of those with and without allergic symptoms then completed a longer questionnaire and donated serum for IgE analysis by ImmunoCAP for 24 foods, 6 aeroallergens and, by allergen microarray, for 48 individual food proteins. RESULTS: The prevalence of IgE sensitization to foods ranged from 23.6% to 6.6%. The least common IgE sensitizations were to fish (0.2%), milk (0.8%) and egg (0.9%), and the most common were to hazelnut (9.3%), peach (7.9%) and apple (6.5%). The order of prevalence of IgE sensitization against different foods was similar in each centre and correlated with the prevalence of the pollen-associated allergens Bet v 1 and Bet v 2 (r = 0.86). IgE sensitization to plant allergen components unrelated to pollen allergens was more evenly distributed and independent of pollen IgE sensitization (r = -0.10). The most common foods containing allergens not cross-reacting with pollens were sesame, shrimp and hazelnut. DISCUSSION: IgE sensitization to foods is common, but varies widely and is predominantly related to IgE sensitization to pollen allergens. IgE sensitization to food allergens not cross-reacting with pollens is rare and more evenly distributed.

Validation of the Spanish-language version of the Montreal Cognitive Assessment as a screening test for cognitive impairment in multiple sclerosis.

BACKGROUND: The neuropsychological batteries traditionally used for the assessment of cognitive impairment (CI) in patients with multiple sclerosis are complex tests requiring a long time to administer. Simpler tests are needed to detect cognitive impairment in daily clinical practice. OBJECTIVE: We aimed to evaluate the diagnostic validity and reliability of the Montreal Cognitive Assessment (MoCA) test as a screening tool for CI in patients with multiple sclerosis, as compared against the Brief Neuropsychological Battery. MATERIAL AND METHODS: We recruited 52 patients with multiple sclerosis (61.5% women; mean age [standard deviation]: 41.7 [11.5] years). We analysed the reliability (internal consistency, interobserver reliability, and test-retest reliability), construct validity (factor analysis, Pearson correlation coefficient, and coefficient of determination), and criterion validity (ROC curve, sensitivity, specificity, total agreement, positive and negative predictive values, positive and negative likelihood ratios, and Fagan nomogram) of the MoCA test in this population. RESULTS: The prevalence of CI was 21.2% according to findings from the Brief Neuropsychological Battery, and 25% according to the MoCA test. The MoCA test showed good internal consistency (Cronbach alpha, 0.822) and interobserver and test-retest reliability (intraclass correlation coefficient 0.80 and 0.96, respectively). The correlation coefficient between total Brief Neuropsychological Battery and MoCA test scores was 0.82. The optimal cut-off point on the ROC curve was 25-26, yielding 91% sensitivity and 93% specificity. CONCLUSION: The MoCA test is a valid and reliable tool for screening for CI in patients with multiple sclerosis.

Effects of two alveolar recruitment manoeuvres (sustained inflation and stepwise) followed by positive end-expiratory pressure on cardiac output (measured with lithium dilution), invasive blood pressure and arterial oxygen tension in isoflurane-anaesthetised goats.

Alveolar recruitment manoeuvres (ARM) performed during general anaesthesia improve oxygenation; however cardiovascular depression may be observed. The aim of the study was to compare the effects of sustained inflation (SI) and stepwise ARMs on cardiac output (CO), mean arterial blood pressure and arterial oxygen tension (PaO2) in ten mechanically ventilated goats anaesthetised with isoflurane. In the SI ARM, peak inspiratory presure (PIP) was increased to 30 cmH2O and sustained for 20 s. In the stepwise ARM, the PIP was increased by 5 cmH2O each minute for three minutes from 10 to 25 cmH2O. Both ARMs were followed by positive end-expiratory pressure of 5 cmH2O. Paired lithium dilution CO measurements and arterial blood samples were obtained before and after each ARM. The order of the ARM was randomised and each goat was subjected to both techniques. Data was reported as median and interquartile range (IQR). Significance was set at 0.05. The median change in CO (measured by subtracting values after and before ARM) was -0.15 L min-1 (IQR -0.51; 0.03) and - 0.90 L min-1 (IQR -1.69; -0.58) for SI and stepwise ARM respectively (p = 0.04). The median change in PaO2 was 3 kPa (IQR -2.7; 7.6) and 0.4 kPa (IQR -3.4; 5.5) for SI and stepwise ARM respectively (p = 0.03). In conclusion, SI ARM causes less impact on CO and provides a better improvement in PaO2 compared to stepwise ARM in goats.

Evaluation of the perception of physical and emotional health of ophthalmologists in Spain and the influence of the COVID-19 pandemic.

OBJECTIVE: The main objective was to study the perception of physical and emotional health of Spanish ophthalmologists and their health habits, as well as the possible influence of the COVID-19 pandemic. METHODS: An observational, cross-sectional, non-randomized and uncontrolled study was carried out among at Spanish ophthalmologists through an online survey of 47 questions on eating habits, tobacco, alcohol, physical exercise, workload, and perception of physical and emotional state. RESULTS: Of a total of 2,179 ophthalmologists, 260 (11.9%) of whom 55% were men responded to the survey, with a mean age of 52.9±11.4 years. 5.8% were smokers. In total, 51.5% reported good physical health, with a mean Body Mass Index of 24.4kg/m2. Overall, 53.5% reported depression, 66.9% tiredness, 34.6% difficulty sleeping, and 57.3% considered their work hard. Up to 28.5% of those surveyed had thought about leaving their job and 60.8% about reorganizing their workload. In total, 91.9% would continue to choose Ophthalmology as a specialty. In total, 36.2% reported an increase in workload, 42.3% worsening of physical state and 63.8% worsening of emotional state as a consequence of the COVID-19 pandemic. CONCLUSIONS: Spanish ophthalmologists have a positive perception of their physical and emotional health, despite having life habits that are not always healthy and feeling mostly down. The COVID-19 pandemic has had a negative influence on the physical and emotional health of ophthalmologists.

Peripapillary and optic nerve head vessel density of glaucoma and healthy subjects from Afro-Caribbean and European descent: A pilot study.

PURPOSE: To compare the peripapillary and optic nerve head vessel density (PP-ONH VD) between glaucoma patients (all, early, moderated, and advanced) and healthy subjects of Afro-Caribbean descent (AD) and European descent (ED). METHODS: This was a cross-sectional study. One eye was evaluated in 90 subjects, including 66 glaucoma patients and 24 healthy subjects, who underwent PP-ONH VD imaging using SPECTRALIS® Optical Coherence Tomography Angiography (OCT-A). We analysed the superficial vascular complex using the AngioTool version 0.6a software. The correlation between the PP-ONH VD and visual field mean deviation (MD) was evaluated using a scatter plot and Spearman's rho correlation coefficient. RESULTS: Among the healthy subjects, the AD group had a lower superficial PP-ONH VD [43.29±3.25% (mean±standard deviation)] than the ED group (46.06±1.75%) (P=0.016). Overall, superficial PP-ONH VD did not show any significant differences between the total AD and ED glaucoma patients or in the subgroup analyses (early/moderate/advanced) (AD: 32.73±6.70%, 37.11±5.72%, 32.48±5.73%, 27.76±4.74%, respectively; ED: 33.94±6.89%, 38.52±3.82%, 35.56±4.18%; 27.65±6.31%, respectively) (P>0.05 for all). A strong, statistically significant correlation was established between vessel density and mean deviation among AD and ED glaucoma patients (r=0.709 and r=0.704, respectively) (P<0.001 for both). CONCLUSION: This pilot study shows that healthy subjects of AD had lower peripapillary and optic nerve head superficial vessel density than healthy subjects of ED, but no significant differences were found between AD and ED glaucoma groups (all, early, moderate, or advanced).

Biometry data and prevalence of corneal astigmatism in caucasian spanish candidates for cataract surgery.

PURPOSE: To describe ocular biometric parameters and the prevalence of corneal astigmatism as well as age and gender correlations in a population of cataract surgery candidates and to estimate the number of eyes that would be candidates for a toric intraocular lens (IOL). METHODS: In consecutive patients requiring cataract surgery over a one-year period (June 2016 to June 2017), the following optical biometry measurements were performed on an IOLMaster 700 or Lenstar 900: axial length (AL), anterior chamber depth (ACD), lens thickness (LT), mean keratometry (K), flat keratometry (K1), steep keratometry (K2), corneal astigmatism (Cyl) and white-to-white diameter (WTW). Descriptive statistics for the demographic and biometric data were analyzed. RESULTS: The study sample included 6111 eyes of 3332 patients (59.3% women), with a mean age of 74.78±9.7years. The means of the compiled data are as follows: AL 23.58±1.55mm, ACD 3.08±0.41mm, LT 4.55±0.52mm,K 44.15±1.54 diopters (D), K1 43.64±1.57 D, K2 44.69±1.61 D, Cyl 1.0±0.81. D and WTW 11.88±0.46mm. The male patients had significantly larger eyes (higher AL, ACD and WTW) and flatter corneas (lower flat and steep K). Older patients had significantly lower AL, ACD and WTW, while their LT values were higher. Corneas became significantly steeper with age. 60.5% of eyes had less than 1 D of corneal astigmatism, while 3.1% had ≥3.0 D. CONCLUSIONS: Less than 1 D of corneal astigmatism was present in the majority of cataract surgery candidates. 3.1% of eyes were candidates for a toric IOL. This study provides useful information on inventory requirements for planning hospital resources.

Biomarkers and intermediate-high risk non-muscle invasive bladder cancer: a multivariate analysis of three different cellular pathways with pronostic implications.

PURPOSE: To determine the presence of a group of mutations, and establish the prognostic value for recurrence and progression. MATERIALS AND METHODS: Prospective observational study. Intermediate-to-high-risk non-muscle invasive bladder cancer (NMIBC) was evaluated. Data from genetic analyses were included in a database along with clinicopathological variables of interest. RESULTS: Seventy-four patients. Twenty-five (33.8%) recurred and 3 (4.1%) progressed. Median time to recurrence: 8 months (5.7-12.7). Median time to progression: 14 months (P75: 12). Mutation distribution: KRAS codon 12: one patient (1.4%), BAT25: five patients (6.8%), BAT-26: four patients (5.4%), and D2S123: 6 patients (8.1%). Arg72Pro polymorphism: 50 patients (67.6%) exhibited homozygous mutations, 23 (31.1%) were heterozygous, and 1 patient (1.4%) did not present the mutation. We found an association between presence of MSI at BAT26 and female sex (p < 0.05) and tumor stage and the TP53 Arg72Pro polymorphism. Recurrence-free survival (RFS) was significantly associated with presence of MSI at D2S123, with a HR of 5.44 for patients presenting the mutation (95% CI 1.83-16.16). On multivariate analysis, we found a statistically significant increase in risk of recurrence among patients with MSI at D2S123 (HR 5.15; p < 0.05) and more than 2 previous transurethral bladder resections (TURBs) (HR 5.07; p < 0.05) adjusted for tumor stage and grade. Harrell's concordance index revealed an accuracy of 0.74 (p < 0.05). CONCLUSION: An association was found between presence BAT26 MSI and female sex, Arg72Pro polymorphism with tumor stage and D2S123 and more than 2 TUR procedures were associated with RFS adjusted to tumor stage and grade.

Antimicrobial resistance increased over an 8-year period in Enterobacteriaceae cultured from canine urine samples.

OBJECTIVES: The aims of the present study were to describe the prevalence of positive urinary bacterial culture in dogs, to identify the most commonly isolated microorganisms and to analyse changes in antimicrobial susceptibility patterns over time. MATERIAL AND METHODS: A retrospective case series was performed using culture and susceptibility results from canine urine samples collected between January 2010 and December 2017. The presence or absence of infection, identity of the bacterium with heaviest growth, and susceptibility profile were recorded for each sample. Trends in the frequency of positive culture and antimicrobial resistance were assessed by Poisson regression modelling. Prevalence rate ratio and 95% confidence interval were reported for resistance to each antimicrobial. RESULTS: A positive urine culture was documented in 771 (22.5%) of 3420 samples. Escherichia coli was the most commonly isolated microorganism. There was no significant increase in the frequency of positive bacterial culture over the study period (prevalence rate ratio 0.98; 95% confidence interval: 0.92 to 1.0). Overall, there was an increase in antimicrobial resistance within Enterobacteriaceae from 5.2 to 35.6%. The prevalence of multidrug-resistant bacteria varied from year to year throughout the study period. However, the Poisson regression model identified a significant increase in the frequency of multidrug-resistant Enterobacteriaceae over this period, averaging approximately 22% per year (prevalence rate ratio 1.22, 95% confidence interval: 1.06 to 1.42). CLINICAL SIGNIFICANCE: The significant increase in antimicrobial resistance observed in this study is concerning and may have implications for veterinary and public health. Appropriate measures, such as antibiotic stewardship programmes, should be implemented to address increasing antimicrobial resistance.

Identification of Senior At Risk scale predicts 30-day mortality among older patients with acute heart failure. / La escala Identification of Senior at Risk predice la mortalidad a los 30 días en los pacientes mayores con insuficiencia cardiaca aguda.

OBJECTIVE: To assess the value of frailty screening tool (Identification of Senior at Risk [ISAR]) in predicting 30-day mortality risk in older patients attended in emergency department (ED) for acute heart failure (AHF). DESIGN: Observational multicenter cohort study. SETTING: OAK-3 register. SUBJECTS: Patients aged ≥65 years attended with ADHF in 16 Spanish EDs from January to February 2016. INTERVENTION: No. VARIABLES: Variable of study was ISAR scale. The outcome was all-cause 30-day mortality. RESULTS: We included 1059 patients (mean age 85±5,9 years old). One hundred and sixty (15.1%) cases had 0-1 points, 278 (26.3%) 2 points, 260 (24.6%) 3 points, 209 (19.7%) 4 points, and 152 (14.3%) 5-6 points of ISAR scale. Ninety five (9.0%) patients died within 30 days. The percentage of mortality increased in relation to ISAR category (lineal trend P value <.001). The area under curve of ISAR scale was 0.703 (95%CI 0.655-0.751; P<.001). After adjusting for EFFECT risk categories, we observed a progressive increase in odds ratios of ISAR scale groups compared to reference (0-1 points). CONCLUSIONS: scale is a brief and easy tool that should be considered for frailty screening during initial assessment of older patients attended with AHF for predicting 30-day mortality.

Validation of the Spanish-language version of the Montreal Cognitive Assessment as a screening test for cognitive impairment in multiple sclerosis. / Validación de la versión española de la Escala Cognitiva de Montreal (MoCA) como herramienta de cribado de deterioro cognitivo asociado a la esclerosis múltiple.

INTRODUCTION: The neuropsychological batteries traditionally used for the assessment of cognitive impairment (CI) in patients with multiple sclerosis are complex tests requiring a long time to administer. Simpler tests are needed to detect cognitive impairment in daily clinical practice. OBJECTIVE: We aimed to evaluate the diagnostic validity and reliability of the Montreal Cognitive Assessment (MoCA) test as a screening tool for CI in patients with multiple sclerosis, as compared against the Brief Neuropsychological Battery. MATERIAL AND METHODS: We recruited 52 patients with multiple sclerosis (61.5% women; mean age [standard deviation]: 41.7 [11.5] years). We analysed the reliability (internal consistency, interobserver reliability, and test-retest reliability), construct validity (factor analysis, Pearson correlation coefficient, and coefficient of determination), and criterion validity (ROC curve, sensitivity, specificity, total agreement, positive and negative predictive values, positive and negative likelihood ratios, and Fagan nomogram) of the MoCA test in this population. RESULTS: The prevalence of CI was 21.2% according to findings from the Brief Neuropsychological Battery, and 25% according to the MoCA test. The MoCA test showed good internal consistency (Cronbach alpha, 0.822) and interobserver and test-retest reliability (intraclass correlation coefficient 0.80 and 0.96, respectively). The correlation coefficient between total Brief Neuropsychological Battery and MoCA test scores was 0.82. The optimal cut-off point on the ROC curve was 25-26, yielding 91% sensitivity and 93% specificity. CONCLUSION: The MoCA test is a valid and reliable tool for screening for CI in patients with multiple sclerosis.

Oncologic outcomes in 408 consecutive patient cohort treated with da Vinci robot-assisted radical prostatectomy. / Resultados oncológicos de un programa de prostatectomía radical asistida por robot «da Vinci¼ en una cohorte de 408 pacientes consecutivos.

The objective of this study is to evaluate the general characteristics and oncological results in a cohort of 408 cases submitted to da Vinci Standard 4-armed robot-assisted radical prostatectomy (RARP), performed between October 2006 and February 2015 at Clínico San Carlos hospital. Statistical analysis was performed with the SPSS 20.0 program. Qualitative variables are presented with their frequency distribution and quantitative variables with their mean and standard deviation or median and interquartile range. The χ2 test was used to analyze the association of qualitative variables. The disease-free survival outcome variable was evaluated with a Kaplan-Meier curve analysis, and the differences were contrasted with the Breslow test. A Cox regression model was adjusted. Among the results, we highlight the follow-up of 47 months (32-68.75m), recurrence-free survival of 90 months (95% CI, 86-94), median time to recurrence of 23 months (10.5-37 m), recurrence 16'6% (68/408), biochemical recurrence (62/498, 15'2%) and 22% of complications, mostly Clavien I-II. The results are summarized in Tables 1 to 7 and Figure 1. CONCLUSIONS: 1) RARP is a safe technique with an acceptable percentage of complications, mostly minor (Clavien grades iandii), 2) We found a higher probability of remaining recurrence-free in the lower grades of the ISUP classification and a higher probability of recurrence in high-risk cases, and 3) The multivariate model showed that the ISUP grade was significantly related to survival and the ISUP and PSM classification grades were independent prognostic variables.

Prevalence of low HDL cholesterol, and relationship between serum HDL and cardiovascular disease in elderly Spanish population: the PREV-ICTUS study.

OBJECTIVE: To assess the prevalence of low serum high-density lipoprotein cholesterol (HDL-C) concentration and the relationship between HDL-C and established cardiovascular disease (CVD) in an elderly Mediterranean population. METHODS: Analysis of Prevención del Riesgo de Ictus, a population-based study on Spanish subjects aged > or = 60 years. Low HDL-C was defined following the European guidelines for cardiovascular prevention [men: < 40 mg/dl (< 1.0 mmol/l); women: < 46 mg/dl (< 1.2 mmol/l)]. The relationship between low HDL-C or HDL-C concentration (in quintiles) and CVD was assessed through multivariate models that included cardiovascular risk factors, statins and subclinical organ damage. RESULTS: On 6010 subjects (71.7 years, 53.5% women), low HDL-C was present in 17.5% [95% confidence interval (CI): 16.5-18.5] and was more frequent in women [20.4% (19.0-21.8) vs. 14.1% (12.8-15.4) in men p < 0.001] and in patients with diabetes, CVD or statin therapy. Low HDL-C was independently associated with CVD [adjusted odds ratio (OR): 1.46, 95% CI: 1.22-1.74, p < 0.001]. The prevalence of CVD was higher as HDL-C concentration was lower (chi-square trend < 0.001). Compared with the highest quintile [> 65 mg/dl (> 1.67 mmol/l)], adjusted OR for CVD were 1.39 (1.10-1.76), 1.41 (1.11-1.80), 1.49 (1.18-1.89) and 1.91 (1.52-2.39), respectively for those in the fourth [57-65 mg/dl (1.46-1.67 mmol/l)], third [51-56 mg/dl (1.31-1.45 mmol/l)], second [46-50 mg/dl (1.18-1.30 mmol/l)] and first [< 46 mg/dl (< 1.18 mmol/l)] quintiles of HDL-C. This association was seen in males and females. CONCLUSIONS: A total of 17.5% of this Spanish population aged > or = 60 years had low HDL-C. We found a strong, independent and inverse association between HDL-C concentrations and established CVD, even at ranges of HDL-C considered as normal.

[Validity and reliability of bladder ultrasound imaging for noninvasive estimation of urine volume in a major outpatient surgery department]. / Validez y fiabilidad de la ecografía vesical en la estimación no invasiva del volumen de orina en una Unidad de cirugía mayor ambulatoria.

OBJECTIVE: To assess the validity and reliability of bladder ultrasound imaging for noninvasive estimation of urine volume, residual volume after voiding, volume before anesthetic induction and after surgery, and volume on sensing an urge to void. PATIENTS AND METHODS: Study of a prospective series of 47 ASA 1-3 patients aged 18 to 79 years undergoing major outpatient surgical procedures under general anesthesia (n = 24) or regional anesthesia and sedation (n = 23). Urine volume was measured at baseline and on recovery (bladder volume by ultrasound and voided volume in a flask) and at the end of surgery (ultrasound only). The reliability and validity of the ultrasound estimation was calculated. RESULTS: Agreement (intraclass correlation coefficient [ICC]) between 4 ultrasound-image estimations at baseline and the measured amount collected in a flask ranged from 0.70 to 0.86. The inter- and intra-measurement reliability was high, with ICC values greater than 0.80. The median error of estimation by ultrasound, with respect to measurement in the flask, was 23% at baseline and 29% after recovery. The amount in the flask was greater. CONCLUSIONS: Ultrasound monitoring of urine in the bladder is reliable and valid, particularly for small volumes. The procedure is tolerated by patients.
