Background: Identifying children and adolescents with cardiometabolic risk at an early stage is crucial for effective treatment and prevention. From a practical perspective, this could be accomplished by assessing the presence of abdominal obesity, which serves as a surrogate indicator of increased cardiometabolic risk and is easy to measure. However, the assessment of abdominal obesity via waist circumference has not yet become a standard procedure in pediatric healthcare. The present study aimed to analyze the secular trends in increased cardiometabolic risk, as indicated by waist circumference among Spanish children and adolescents., Methods: This study included 4861 children and adolescents aged 8 to 16 years from two nationwide representative cross-sectional surveys, the EnKid study and the PASOS study, conducted in 1998-2000 and 2019-2020, respectively. Anthropometric variables were measured in both surveys by trained personnel. Three different waist-to-height (WHtR) cutoffs were used to define abdominal obesity as criteria for cardiometabolic risk. BMI categories were defined according to the IOTF and WHO growth charts., Results: Abdominal obesity [waist to height ratio (cm/cm) > 0.49] significantly increased from 40.7 to 56.1% and 93.8 to 97.2% in participants with overweight and obesity, respectively, between 1998-2000 and 2019-2020 (p < 0.05). Logistic regression analysis, adjusted for sex and age, revealed that the odds of being at increased cardiometabolic risk in 2019-2020 was 1.99 (95% CI 1.48-2.67) in participants with overweight in comparison with 1998-2000. The effect size was comparable among the three WHtR criteria for abdominal obesity or the BMI categories according to IOTF and WHO boundaries., Conclusions: The prevalence of Spanish children with increased cardiometabolic risk, identified by abdominal obesity, significantly increased among those with overweight during the last two decades. This finding underlines the need of including the measurement of waist circumference as a standard procedure in pediatric practice., (© 2024. The Author(s).)

Childhood obesity is a public health problem worldwide. An important determinant of child and adolescent obesity is socioeconomic status (SES). However, the magnitude of the impact of different SES indicators on pediatric obesity on the Spanish population scale is unclear. The aim of this study was to assess the association between three SES indicators and obesity in a nationwide, representative sample of Spanish children and adolescents. A total of 2791 boys and girls aged 8 to 16 years old were included. Their weight, height, and waist circumference were measured. SES was assessed using two parent/legal guardian self-reported indicators (educational level -University/non-University- and labor market status -Employed/Unemployed-). As a third SES indicator, the annual mean income per person was obtained from the census section where the participating schools were located (≥12.731€/<12.731€). The prevalence of obesity, severe obesity, and abdominal obesity was 11.5%, 1.4%, and 22.3%, respectively. Logistic regression models showed an inverse association of both education and labor market status with obesity, severe obesity, and abdominal obesity (all p < 0.001). Income was also inversely associated with obesity ( p < 0.01) and abdominal obesity ( p < 0.001). Finally, the highest composite SES category (University/Employed/≥12.731€ n = 517) showed a robust and inverse association with obesity (OR = 0.28; 95% CI: 0.16-0.48), severe obesity (OR = 0.20; 95% CI: 0.05-0.81), and abdominal obesity (OR = 0.36; 95% CI: 0.23-0.54) in comparison with the lowest composite SES category (Less than University/Unemployed/<12.731€; n = 164). No significant interaction between composite SES categories and age and gender was found. SES is strongly associated with pediatric obesity in Spain.

Objective: Obesity is an inflammatory disease that is widely distributed in the world's population and is related to the leading causes of death. The use of prebiotics and probiotics can be an alternative treatment against obesity. Although there have been found physiological and biochemical effects of its use, the molecular mechanism remains unclear. The present review analyzed articles that suggested the activation of pathways related to the metabolism of the fatty acids, as well as the impact on anti-inflammatory mechanisms, as part of the mechanism of action of prebiotics and probiotics, to know therefore the possible pathways activated by the prebiotics and probiotics., Methods: Exhaustive research was made on articles included in the period 2005-2021 related to the effect of prebiotics and probiotics in obesity, inflammatory diseases, and metabolic diseases. Identifying an effect on anti-inflammatory cytokines and PPAR modulation, with a consequent decrease in inflammation and fat degradation., Results: A total of sixty-three articles were obtained, which were classified as basic information on molecular markers of obesity, the effect of prebiotics and probiotics in obesity, and articles related to anti-inflammatory effects and fatty acid metabolism observed in obesity and other inflammatory diseases., Conclusions: The effect of prebiotics and probiotics in obesity can be linked to the anti-inflammatory mechanism produced, and this effect leads to an increase in the expression of genes related to fatty acid metabolism.

A progressive shift away from traditional healthy dietary patterns, such as the Mediterranean diet (MedDiet), has been observed in recent decades. The aim of this study was to assess determinants of optimal adherence to the MedDiet in Spanish children and adolescents. A cross-sectional analysis was included in the PASOS nationwide representative study in Spain. Participants were 3607 children and adolescents; 8-16 years old. Primary and secondary outcome measures of weight and height were measured. Adherence to the MedDiet, physical activity, and sedentary behavior in children and adolescents, as well as parental physical activity and dietary habits, were assessed. Optimal adherence to the MedDiet was observed in 45.5% of primary school students and 34.8% of secondary school students (OR: 0.65; 95%CI: 0.56-0.75). Optimal adherence to the MedDiet was higher in children/adolescents meeting daily recommended moderate and vigorous physical activity (OR: 2.39, 95%CI: 1.97-2.89) and in those meeting daily recommended screen time on weekdays (OR: 2.05, 95%CI: 1.77-2.38) and weekends (OR: 1.76, 95%CI: 1.48-2.10). Participants with optimal adherence to the MedDiet were more likely to have mothers with a high-level education and high-tercile of SDQS, mothers who never smoked or were former smokers, and mothers who met the recommended physical activity and screen time. It can be concluded that a low prevalence of optimal adherence to the MedDiet was found among current Spanish children and adolescents. Optimal adherence to the MedDiet was associated with reaching the recommendations on physical activity and screen time, with the highest maternal educational level, and healthier maternal lifestyles.

Background and Aims: The World Health Organization recommended simultaneous measurement of body mass index (BMI) and waist circumference (WC) and suggested joint use to predict disease risks. The aim of this study was to assess the prevalence of BMI and waist-to-height ratio (WHtR) categories among Spanish children and adolescents, as well as their associations with several lifestyle factors., Methods: Cross-sectional analysis of 8-16-year-old children and adolescents ( n = 3772) were included in the PASOS nationwide representative study. Children/adolescents and their mothers/female caregivers answered a questionnaire on lifestyle and health factors. Child/adolescent anthropometrics were measured. Four combined BMI-WHtR disease risk categories were built., Results: A third of participants showed combined BMI-WHtR categories with high disease risk (12.3% 'increased risk', 9.7% 'high risk', 14.3% 'very high risk'). Participants in the 'very high risk' group were less likely to be females (odds ratio 0.63; 95% CI: 0.52-0.76) and adolescents (0.60; 95% CI: 0.49-0.72), to practice ≥60 min/day of moderate-vigorous physical activity (MVPA) (0.73; 95% CI: 0.57-0.93), and to watch <120 min/day of total screen time on weekdays (0.61; 95% CI: 0.49-0.76). Mothers of participants in the 'very high risk' group were less likely to have a high educational level, be in the overweight or normal range, have never smoked or were former smokers, and watch <120 min/day of total screen time on weekends. Participants in the 'increased' and 'high risk' categories had mothers with normal weight and ≥60 min/day of MVPA. Participants in the 'high risk' group did not achieve ≥60 min/day of MVPA and showed lower adherence to the Mediterranean diet., Conclusions: Adherence to a healthy lifestyle in children and adolescents, but also in their mothers/female caregivers during offspring's childhood and adolescence, is associated with low BMI-WHtR disease risk.

Background: The aim of this study is to determine the current status of Spanish Hospital Emergency Services (HES) in diagnosing and treating the most prevalent tropical diseases (TD) in Spain., Methods: A cross-sectional descriptive study was carried out, using a questionnaire in Google Forms® sent to members of the INFURG-SEMES group. The following variables were analyzed: the size of the hospital in terms of number of beds, number of tropical disease emergencies, existence of tropical medicine protocols, urgent diagnostic tests or antimalarial treatment., Results: The form was sent to 75 hospitals. Responses were obtained from 42 emergency services (55%) in 10 Autonomous Communities. Twenty-four (57.1%) had >500 beds. Only five hospitals (11.9%) have the facilities to diagnose malaria and dengue 24 hours a day. There was no tropical disease protocol in 19 (45.3%) hospitals. Seven (16.7%) hospitals had =?10 attendances/day. Larger hospitals were more likely to have an infectious disease unit independent from Internal Medicine service, along with a tropical medicine unit, and an on-call infectious disease specialist and microbiologist. There are no statistically significant differences between larger and smaller hospitals in terms of their capacity to carry out appropri-ate diagnoses or treatments in 24 hours., Conclusion: Care and treatment of emerging diseases are now a sizeable percentage of the consultations at an HES. Such units generally lack specific protocols, particularly for malaria. Urgent diagnostic testing for malaria is also needed.

Introduction and Objectives: The COVID-19 outbreak has had an unclear impact on the treatment and outcomes of patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to assess changes in STEMI management during the COVID-19 outbreak., Methods: Using a multicenter, nationwide, retrospective, observational registry of consecutive patients who were managed in 75 specific STEMI care centers in Spain, we compared patient and procedural characteristics and in-hospital outcomes in 2 different cohorts with 30-day follow-up according to whether the patients had been treated before or after COVID-19., Results: Suspected STEMI patients treated in STEMI networks decreased by 27.6% and patients with confirmed STEMI fell from 1305 to 1009 (22.7%). There were no differences in reperfusion strategy (> 94% treated with primary percutaneous coronary intervention in both cohorts). Patients treated with primary percutaneous coronary intervention during the COVID-19 outbreak had a longer ischemic time (233 [150-375] vs 200 [140-332] minutes, P<.001) but showed no differences in the time from first medical contact to reperfusion. In-hospital mortality was higher during COVID-19 (7.5% vs 5.1%; unadjusted OR, 1.50; 95%CI, 1.07-2.11; P <.001); this association remained after adjustment for confounders (risk-adjusted OR, 1.88; 95%CI, 1.12-3.14; P=.017). In the 2020 cohort, there was a 6.3% incidence of confirmed SARS-CoV-2 infection during hospitalization., Conclusions: The number of STEMI patients treated during the current COVID-19 outbreak fell vs the previous year and there was an increase in the median time from symptom onset to reperfusion and a significant 2-fold increase in the rate of in-hospital mortality. No changes in reperfusion strategy were detected, with primary percutaneous coronary intervention performed for the vast majority of patients. The co-existence of STEMI and SARS-CoV-2 infection was relatively infrequent., (Copyright © 2020 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.)

Objective: The SARS-CoV-2 pandemic conditions high mortality rates in hospitalized elderly. Currently, a few studies include octogenarian patients and none of them analyze the impact of functional status on this health outcome. Our objective is to describe the characteristics of patients older than 80 years hospitalized for coronavirus disease 2019 (COVID-19), to determine the mortality rate and to identify associated factors., Material and Methods: Prospective observational study carried out on patients over 80 years admitted for COVID-19 in a Geriatrics Service. Sociodemographic, clinical, functional, mental, analytical, radiological, therapeutic and healthcare variables were collected. The factors associated with in-hospital lethality were analyzed by bivariate analysis., Results: 58 cases with laboratory-confirmed COVID-19 were included, mean age 88.3 ± 5.4 years, 69% women, 65.5% moderate-severe cognitive impairment and previous Barthel index 40.66 ± 36. The main symptoms were fever (60,3%), dyspnea (53.4%) and deterioration of functional condition (50%). The most frequent comorbidities were cardiovascular disease (75.9%), hypertension (HT) (74.1%) and chronic kidney disease (CKD) (50%). A mortality rate of 41,4% was detected and the associated factors were: severe functional dependence (OR = 3.8 [1.2-12.2]), moderate-severe cognitive impairment (OR = 4.9 [1-25.4]) and CKD (OR = 3.2 [1.1-9.7])., Conclusion: High mortality rates are observed in older patients hospitalized for COVID-19, with a higher risk of dying in those with severe functional dependence or cognitive impairment. These findings reinforce the value of Geriatric Assessment to develop strategies to adapt diagnostic and therapeutic decision-making and to optimize care for elderly patients in the event of a new epidemic outbreak., (Copyright © 2020 SEGG.

Objective: To determine whether isolated patients admitted to hospital have a higher incidence of adverse events (AEs), to identify their nature, impact and preventability., Design: Prospective cohort study with isolated and non-isolated patients., Setting: One public university hospital in the Valencian Community (southeast Spain)., Participants: We consecutively collected 400 patients, 200 isolated and 200 non-isolated, age ≥18 years old, to match according to date of entry, admission department, sex, age (±5 years) and disease severity from April 2017 to October 2018., Exclusion Criteria: patients age <18 years old and/or reverse isolation patients., Primary and Secondary Outcome Measures: The primary outcome as the AE, defined according to the National Study of Adverse Effects linked to Hospitalisation (Estudio Nacional Sobre los Efectos Adversos) criteria. Cumulative incidence rates and AE incidence density rates were calculated., Results: The incidence of isolated patients with AEs 16.5% (95% CI 11.4% to 21.6%) compared with 9.5% (95% CI 5.4% to 13.6%) in non-isolated (p<0.03). The incidence density of patients with AEs among isolated patients was 11.8 per 1000 days/patient (95% CI 7.8 to 15.9) compared with 4.3 per 1000 days/patient (95% CI 2.4 to 6.3) among non-isolated patients (p<0.001). The incidence of AEs among isolated patients was 18.5% compared with 11% for non-isolated patients (p<0.09). Among the 37 AEs detected in 33 isolated patients, and the 22 AEs detected in 19 non-isolated patients, most corresponded to healthcare-associated infections (HAIs) for both isolated and non-isolated patients (48.6% vs 45.4%). There were significant differences with respect to the preventability of AEs, (67.6% among isolated patients compared with 52.6% among non-isolated patients)., Conclusions: AEs were significantly higher in isolated patients compared with non-isolated patients, more than half being preventable and with HAIs as the primary cause. It is essential to improve training and the safety culture of healthcare professionals relating to the care provided to this type of patient., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Introduction: Physical activity (PA) is essential to healthy mental and physical development in early life. However, the prevalence of physical inactivity, which is considered a key modifiable driver of childhood obesity, has reached alarming levels among European youth. There is a need to update the data for Spain, in order to establish if current measures are effective or new approaches are needed., Methods and Analysis: We present the protocol for Physical Activity, Sedentarism, lifestyles and Obesity in Spanish youth (PASOS). This observational, nationally representative, multicentre study aims to determine the PA levels, sedentary behaviours and prevalence of physical inactivity (defined as <60 min of moderate to vigorous PA per day) in a representative sample of Spanish children and adolescents. The PASOS study has recruited a representative random sample of children and adolescents aged 8-16 years from 242 educational centres in the 17 'autonomous regions' into which Spain is divided. The aim is to include a total of 4508 youth participants and their families. Weight, height and waist circumference will be measured by standardised procedures. Adherence to the Mediterranean diet, quality of life, sleep duration, PA and sedentary behaviour are being measured by validated questionnaires. PA is measured by the Physical Activity Unit 7-item Screener. A representative subsample (10% of participants) was randomly selected to wear accelerometers for 9 days to obtain objective data on PA. Parents are asked about their educational level, time spent doing PA, diet quality, self-perceived stress, smoking habit, weight, height, their child's birth weight and if the child was breast fed., Ethics and Dissemination: The study was approved by the Ethics Committee of the Fundació Sant Joan de Déu, Barcelona, Spain. Main findings of the study will be disseminated to the scientific community and to general public by media conferences, social media and a website., Trial Registration Number: ISRCTN34251612., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Extracurricular physical activity in children and adolescents can help achieve compliance with the World Health Organization (WHO) recommendations for physical activity. The purpose of this study was to evaluate factors in school and family environments of children and adolescents in Spain that could be related to the practice of extracurricular physical activity. Multistage random cluster sampling was conducted to include 128 schools with the participation of 10,096 students between the ages of 7 and 16. Participants completed the survey of sports habits designed by the National Sports Council. The results revealed a higher participation in extracurricular sports activities among boys (OR: 1.67 (1.5-1.9)) and students in primary education (up to 12 years old) (OR: 1.8 (1.7-2.0)). Likewise, a statistically significant relationship ( p < 0.005) was observed between families where another family member practiced sports and lower number of screen time hours, improved academic performance, and better self-perceived health. Participation of children and adolescents in extracurricular sports activities seems to be associated with their immediate environment. It is therefore essential to emphasize the importance of establishing physical activity habits from an early age in family and school environments.

Background: Spain has dramatically increased the number of controlled circulatory death donors (cDCD). The initial selection criteria for considering cDCD for kidney transplantation (KT) have been expanded progressively, with practically no limits in donor age during the last years. We aimed to analyze the early clinical outcomes using expanded (> 65 years) cDCD in comparison with standard ones., Methods: Observational multicenter study including 19 transplant centers in Spain. We performed a systematic inclusion in a central database of every KT from expanded cDCD at each participant unit from January-2012 to January-2017. Surgical procedures and immunosuppressive protocols were based on local practices. Data was analyzed in the central office using logistic and Cox regression or competitive-risk models for multivariate analysis. Median time of follow-up was 18.1 months., Results: 561 KT were performed with kidneys from cDCD, 135 from donors older than 65 years. As expected, recipients from older cDCD were also older (65.8 (SD 8.8) vs 53.7 (SD 11.4) years; p < 0.001) and with higher comorbidity. At 1 year, no differences were found amongst older and younger cDCD KT recipients in terms of serum creatinine (1.6 (SD 0.7) vs 1.5 (SD 0.8) mg/dl; p = 0.29). Non-death censored graft survival was inferior, but death-censored graft survival was not different (95.5 vs 98.2% respectively; p = 0.481). They also presented a trend towards higher delayed graft function (55.4 vs 46.7%; p = 0.09) but a similar rate of primary non-function (3.7 vs 3.1%; p = 0.71), and acute rejection (3.0 vs 6.3%; p = 0.135). In the multivariate analysis, in short follow-up, donor age was not related with worse survival or poor kidney function (eGFR < 30 ml/min)., Conclusions: The use of kidneys from expanded cDCD is increasing for older and comorbid patients. Short-term graft outcomes are similar for expanded and standard cDCD, so they constitute a good-enough source of kidneys to improve the options of KT wait-listed patients.

Background: Various recent outbreaks of hepatitis A virus (HAV) have been described in men who have sex with men despite the availability of an effective vaccine. This study aimed to determine the current rates of seroconversion after receiving HAV vaccine (HAV-V) in HIV-infected patients under real-life conditions., Setting: Patients were selected from a Southern Spanish multicentric cohort of HIV-infected subjects., Methods: Retrospective analysis of all patients who received 2 doses (standard scheme) from April 2008 to May 2016 or from June 2016 to February 2018 facing an HAV outbreak with shortage of HAV-V, 1 single dose of HAV-V. Response to HAV-V was defined as positive anti-HAV IgG between 1 and 12 months after the last vaccination dose., Results: A total of 522 patients were included, mainly men who have sex with men (86.2%). In the standard-dose group, 303/343 [88.3%; 95% confidence interval (CI): 84.5 to 91.5] patients showed seroconversion as compared with 149/179 (83.2%; 95% CI: 76.9 to 88.4) of the single-dose group (P = 0.107). Undetectable baseline HIV-RNA (adjusted odds ratio: 4.86; 95% CI: 1.86 to 12.75; P = 0.001) and a CD4 T-cell count ≥350/μL (adjusted odds ratio, 3.96; 95% CI: 1.26 to 12.49; P = 0.019) were independently associated with response to both regimens. A higher CD4/CD8 ratio was also associated with response after a single dose., Conclusions: HIV-infected patients should be encouraged to undergo HAV-V with 2 standard doses 6 months apart; a single dose achieves a high rate of seroconversion in those patients with favorable response factors and may be enough to limit future outbreaks in case of HAV-V shortage until supply is reestablished.

This observational, open, multicenter clinical trial with a single treatment group aimed to evaluate the effectiveness of a dietary supplement whose main ingredients are hydrolyzed gelatin, chondroitin sulfate, glucosamine sulfate, and devil's claw and bamboo extracts for pain reduction and improvement of functional capacities in patients with osteoarthritis (OA) of the knee and/or hip (REDART study). In all, 130 patients with OA recruited from Spanish hospitals received the dietary supplement for 6 months. The primary outcome was the patients' global assessment of pain in the affected joint as measured with a visual analogue scale (VAS). Other outcome measurements included the Lequesne Functional Index (subindexes for pain/discomfort, distance walked, and daily living) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC; subindexes for pain, stiffness, and physical function). Scores were taken at months 3 and 6 of the treatment. Patients ( N = 78) showed a reduction of pain of 3.77 ± 1.77 points after 6 months ( p < .0001) in the VAS. The total reduction in the Lequesne Functional Index was 6.30 ± 4.08 points after 6 months ( p < .0001), with significant reductions in all subindexes of the scale. A similar pattern was found for the WOMAC index, with an overall reduction of 22.49 ± 14.03 points after 6 months ( p < .0001) and significant reductions in all subindexes. No major adverse events were noted during the treatment. This exploratory study shows that treatment with the dietary supplement significantly reduces pain and improves locomotor function in patients with OA of the knee and/or hip.

The south of Iberia conserves an important group of Palaeolithic rock art sites. The graphisms have been mostly attributed to the Solutrean and Magdalenian periods, while the possibility that older remains exist has provoked extensive debate. This circumstance has been linked to both the cited periods, until recently, due to the transition from the Middle to Upper Palaeolithic in the extreme southwest of Europe as well as the non-existence of some of the early periods of Palaeolithic art documented in northern Iberia. This study presents the results of interdisciplinary research conducted in Las Ventanas Cave. These results enabled us to identify a new Palaeolithic rock art site. The technical, stylistic and temporal traits point to certain similarities with the range of exterior deep engravings in Cantabrian Palaeolithic rock art. Ventanas appears to corroborate the age attributed to those kinds of graphic expression and points to the early arrival of the Upper Palaeolithic in the south of Iberia. Importantly, the results provide information on the pre-Solutrean date attributed to trilinear hind figures. These findings challenge the supposed Neanderthal survival idea at one of the main late Middle Palaeolithic southern Iberian sites (Carigüela) and, due to the parallels between them and an engraving attributed to this period in Gibraltar, it raises the possibility of interaction between modern humans and Neanderthals in the extreme southwest of Europe., Competing Interests: The authors have declared that no competing interests exist.

DNA variants at the genes that encode components of the IL17-pathway may contribute to the risk of impaired renal function/chronic kidney disease. Our aim was to determine whether common IL17RA single nucleotide polymorphisms (SNPs) were associated with a reduced estimated glomerular filtration rate (eGFR) in a cohort of healthy elderly individuals (n=650). We found a significantly higher frequency of SNP rs4819554 AA homozygotes among individuals with eGFR<60 ml/min/1.73 m(2) (n=90) (p=0.005, OR=2.11; 1.26-3.54), an effect that was independent of the presence of type 2 diabetes. Allele rs4819554 A had been associated to the risk of developing end stage renal disease, and was also linked to an increased expression of the IL17RA protein and higher levels of Th17 cell subsets. A scenario in which the pro-inflammatory role of the IL17-pathway contributes to kidney damage might explain the association between Il17RA polymorphisms and an impaired renal function., (Copyright © 2015 American Society for Histocompatibility and Immunogenetics.

Background & Aims: (i) To describe the demographic, clinical, virological and histological characteristics of the patients undergoing evaluation for indication of triple therapy against hepatitis C virus genotype 1, and to identify the reasons why candidate patients are excluded; and (ii) to evaluate the characteristics of the healthcare environment related to treatment., Methods: Observational, prospective and multi-centred study involving 16 hospitals of Spain. Data were collected on 1122 patients receiving attention in the outpatient clinics between June and December 2012., Results: Of the 1122 patients evaluated, 769 were finally included in this study; 27% (211/769) had contraindications to the therapy. Of those without contraindications, 54% (301/558) did not receive the treatment, and so, only about a third of the patients (33%-257/769) underwent therapy. The reasons for not initiating therapy were as follows: patient refusal (30%), mild disease/awaiting new treatments (34%), restrictions by the health service (30%), other reasons (6%). In univariate analyses, the probability of receiving treatment was related to: age <60 years, male gender, high education level, advanced fibrosis, having had previous treatment, being assessed in a centre of excellence. In multivariate analyses, the factors independently related to the probability of receiving treatment were as follows: high education level of the patients (P = 0.004), advanced fibrosis (P < 0.001) and centres of excellence (P = 0.009)., Conclusion: Despite the high efficacy of triple therapy, only a small proportion of patients receive the treatment. The causes related to non-treatment depend on patient factors, disease stage and characteristics of the health-service provision., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: To get to know the influence of the four domains of the Chronic Lower Limb Venous Insufficiency Questionnaire (CIVIQ) on the quality of life (QoL) of patients with primary superficial venous incompetence, and their behaviour in relation to age, gender, occupation, body mass index (BMI), and also with respect to the clinical and anatomical classes of the CEAP., Material and Methods: The sample was composed of 468 patients with primary superficial venous reflux (135 male and 333 female) who answered 100% of the questions in the Short Form-12 (SF12) and CIVIQ questionnaires. After a clinical and duplex examination, the patients were categorized as C0-6, Ep, As, Ap or As,p and Pr according to the CEAP classification. The relationships between CIVIQ domains and gender, age, occupation, BMI, and the clinical and anatomical classes of the CEAP classification were analyzed., Results: Men reported better QoL than women (33.2 vs. 46.3) and this was also true for each of the CIVIQ's domains (p < .00). Pain (50.6) and physical restriction (45.3) were the dimensions with a greater influence on QoL, whereas social (41.7) and psychological (38.1) dimensions had a lesser influence. Patients aged between 45 and 64, household activities, and patients with C2-3 clinical classes were the patient groups with the worst scores in all the CIVIQ dimensions and those where significant differences were found. The BMI and anatomical distribution of the reflux had no influence on the QoL., Conclusions: Pain and physical restriction were the CIVIQ domains with greater influence on the QoL of patients with primary superficial venous reflux. Age increase (up to 64 years), female gender, household activities, and C2-3 CEAP clinical class were the main factors associated with the worst QoL perception., (Copyright © 2014 European Society for Vascular Surgery.

Purpose: Evaluate the diagnostic performance of contrast enhanced CT/PET (ceCT/PET) in the response assessment of patients with colorectal cancer liver metastases., Methods: 33 ce CT/PET studies of 19 patients with colorectal liver metastases were prospectively evaluated. All of them, 13 (68.4%) were males and 6 (31.6%) females. Mean age and range were 63 [42-78]. All patients were treated with neoadjuvant chemotherapy. In all cases post-therapy diagnostic confirmation of liver lesions was obtained. A ce CT PET/was obtained 1h after the injection of 370 MBq of 18F-FDG. Metabolic and morphologic studies were evaluated by two blinded nuclear physicians and radiologists respectively to assess the location, size and suspected diagnosis of lesions (benign or malignant). A combined assessment of both techniques was performed. The final diagnosis was established by histopathology or clinical/radiological follow-up greater than 6 months., Results: A total of 120 liver lesions were identified, 115 were malignant and 5 benign. From the malignant lesions, 105 were identified with the ceCT, 44 with the PET and 109 with ceCT/PET. All of the benign lesions were correctly classified with any of the three imaging techniques. The sensitivity of PET, ceCT and ceCT/PET were of 38%, 91% and 95% respectively and the specificity was 100% in all three of the diagnostic studies., Conclusion: Administration of intravenous contrast in the PET/CT is mandatory to evaluate treatment response rate of liver metastases due to the limitations of isolated metabolic images in these cases., (Copyright © 2013 Elsevier Ireland Ltd.

The aim of the paper is to analyse the prevalence of liver involvement and related factors in HIV-infected patients with early syphilis (<2 years). Liver involvement was defined as an elevation above normal ranges of alanine transaminase, aspartate aminotransferase, gamma-glutamyltransferase and/or alkaline phosphatase during early syphilis, or doubling of previous levels in patients with liver enzyme elevation before syphilis. We undertook a multicentre study and of the 147 cases, 86.4% were men who had sex with men, and the diagnoses of syphilis and HIV infection were coincident in 48 (32.7%). Liver involvement was detected in 45 (30.6%) and the only related factor was a rapid plasma reagin (RPR) titre ≥1/64 (odds ratio 3.76; 95% confidence interval 1.3-10.5; P = 0.012). In conclusion, liver involvement occurs in around one-third of HIV-infected patients with early syphilis and is associated with high RPR levels. Syphilis should be included in the differential diagnosis of liver enzyme elevation in HIV-infected patients.

Low-fat pork liver pâtés enriched with n-3 PUFA/konjac gel were formulated by replacing (totally or partially) pork backfat by a combination of healthier oils (olive, linseed and fish oils) and konjac gel. Lipid oxidation, microbiological changes and biogenic amine (BA) formation were studied in healthier-lipid pâtés during chill storage (85 days, 2 °C). Increasing unsaturated fatty acid levels favoured lipid oxidation, although the levels reached were low throughout the storage period, ranging from 0.113 to 0.343 mg malonaldehyde/kg sample. Neither the formulation nor the time in storage affected the microbial load. Biogenic amine contents of products (the sum of initial concentrations and amines formed during storage) varied according to the type of BA but were far below levels that could constitute a consumer health hazard., (Copyright © 2012 Elsevier Ltd.

Inappropriate speed is a major cause of traffic accidents. Different measures have been considered to control traffic speed, and intelligent speed adaptation (ISA) systems are one of the alternatives. These systems know the speed limits and try to improve compliance with them. This paper deals with an informative ISA system that provides the driver with an advance warning before reaching a road section with singular characteristics that require a lower safe speed than the current speed. In spite of the extensive tests performed using ISA systems, few works show how warnings can be adapted to the driver. This paper describes a method to adapt warning parameters (safe speed on curves, zone of influence of a singular stretch, deceleration process and reaction time) to normal driving behavior. The method is based on a set of tests with and without the ISA system. This adjustment, as well as the analysis of driver acceptance before and after the adaptation and changes in driver behavior (changes in speed and path) resulting from the tested ISA regarding a driver's normal driving style, is shown in this paper. The main conclusion is that acceptance by drivers increased significantly after redefining the warning parameters, but the effect of speed homogenization was not reduced., (Copyright © 2010 Elsevier Ltd.

The occurrence of in vitro amino acid activity in bacterial strains associated with fresh pork sausages packaged in different atmospheres and kept in refrigeration was studied. The presence of biogenic amines in decarboxylase broth was confirmed by ion-exchange chromatography and by the presence of the corresponding decarboxylase genes by PCR. From the 93 lactic acid bacteria and 100 enterobacteria strains analysed, the decarboxylase medium underestimates the number of biogenic amine-producer strains. 28% of the lactic acid bacteria produced tyramine and presented the tdc gene. All the tyramine-producer strains were molecularly identified as Carnobacterium divergens. Differences on the relative abundance of C. divergens were observed among the different packaging atmospheres assayed. After 28 days of storage, the presence of argon seems to inhibit C. divergens growth, while packing under vacuum seems to favour it. Among enterobacteria, putrescine was the amine more frequently produced (87%), followed by cadaverine (85%); agmatine and tyramine were only produced by 13 and 1%, respectively, of the strains analysed. Packing under vacuum or in an atmosphere containing nitrogen seems to inhibit the growth of enterobacteria which produce simultaneously putrescine, cadaverine, and agmatine. Contrarily, over-wrapping or packing in an atmosphere containing argon seems to favour the growth of agmatine producer-enterobacteria. The production of putrescine and cadaverine was associated with the presence of the corresponding amino acid decarboxylase genes. The biogenic amine-producer strains were included in a wide range of enterobacterial species, including Kluyvera intermedia, Enterobacter aerogenes, Yersinia kristensenii, Serratia grimesii, Serratia ficaria, Yersinia rodhei, Providencia vermicola and Obesumbacterium proteus., (Copyright © 2011 Elsevier Ltd.

Introduction: Malaria has increased in Spain, and is potentially severe in children. Information on pediatric malaria in Spain is scarce. The aim is to evaluate the clinical, therapeutic and epidemiological characteristics of children diagnosed with malaria in our hospital., Patients and Methods: A retrospective descriptive study was performed on all pediatric cases of malaria diagnosed in Getafe University Hospital, from January 1995 to November 2006. Epidemiological and clinical features, as well as diagnostic methods, treatments and outcome were studied. An analysis of two comparative periods (before and after January 2000) was carried out., Results: Eighteen cases of confirmed malaria were identified, twelve girls and six boys. The age range was from 13 months to 13 years with a median age of 60 months. All patients had recently travelled to or from endemic countries. Despite having a stable number of admissions to hospital over time, all but two patients were diagnosed in the second period (P<0.01). Fever and gastrointestinal symptoms were the most common symptoms, with liver or spleen enlargement in 75%. Thrombocytopenia and anemia were common. No cases of complicated malaria or death occurred. Plasmodium identification by microscopic examination was used in all cases. Identification of Plasmodium species with PCR was carried out in 16 children. P. falciparum was found in 89% of these cases. Quinine-sulphate and clindamycin were used in 72%., Conclusions: The incidence of pediatric malaria is increasing in the southern area of Madrid, with P. falciparum as the most frequently identified species. Microscopic visualization or identification of its antigen are gold-standard diagnostic methods, however, identification with PCR is essential upon admission to determine the species and discard possible multiple infestations. Pediatricians must learn to suspect this potentially severe disease, in order to establish an early treatment that may improve the prognosis.

Introduction: Spontaneous pneumothorax (SP) is a frequent complication in non-treated HIV-infected patients as a complication of opportunistic infections and tumours., Objective: To analyse the aetiology of SP in non-treated HIV patients., Patients and Methods: Observational study of SP cases observed in a cohort of 9831 of non-treated HIV-infected patients attended in seven Spanish hospitals., Results: 105 patients (1.06%) developed SP. The aetiological cause was identified in 89 patients. The major causes identified were: bacterial pneumonia (36 subjects, 34.3%); Pneumocystis jiroveci pneumonia (PJP) (31 patients, 29.5%); and pulmonary tuberculosis (17 cases, 15.2%). The most common cause of SP in drugs users was bacterial pneumonia (40%), whereas PJP was more common (65%) in sexual transmitted HIV-patients. The most common cause of bilateral SP was PJP (62.5%) whereas unilateral SP was most commonly associated with bacterial pneumonia (40.2%). The most common cause of SP in patients with a CD4+ lymphocyte count >200 cells/ml and in patients without AIDS criteria was bacterial pneumonia. PJP was the more common cause in patients with a CD4+ lymphocyte count <200 cells/ml or with AIDS., Conclusion: The incidence of SP in non-treated HIV-infected patients was 1.06%. The aetiology was related to the patients risk practices and to their degree of immunosuppression. Bacterial pneumonia was the most common cause of SP.

The geology and climate of the western Mediterranean area were strongly modified during the Late Tertiary and the Quaternary. These geological and climatic events are thought to have induced changes in the population histories of plants in the Iberian Peninsula. However, fine-scale genetic spatial architecture across western Mediterranean steppe plant refugia has rarely been investigated. A population genetic analysis of amplified fragment length polymorphism variation was conducted on present-day, relict populations of Ferula loscosii (Apiaceae). This species exhibits high individual/population numbers in the middle Ebro river valley and, according to the hypothesis of an abundant-centre distribution, these northern populations might represent a long-standing/ancestral distribution centre. However, our results suggest that the decimated southern and central Iberian populations are more variable and structured than the northeastern ones, representing the likely vestiges of an ancestral distribution centre of the species. Phylogeographical analysis suggests that F. loscosii likely originated in southern Spain and then migrated towards the central and northeastern ranges, further supporting a Late Miocene southern-bound Mediterranean migratory way for its oriental steppe ancestors. In addition, different glacial-induced conditions affected the southern and northern steppe Iberian refugia during the Quaternary. The contrasting genetic homogeneity of the Ebro valley range populations compared to the southern Iberian ones possibly reflects more severe bottlenecks and subsequent genetic drift experienced by populations of the northern Iberia refugium during the Pleistocene, followed by successful postglacial expansion from only a few founder plants.

Objectives: To study the prevalence of cognitive decline and dementia in the residential environment, the pharmacological and non-pharmacological treatments used, and the possible existence of undiagnosed dementia., Material and Methods: We performed a cross-sectional epidemiological study in a population of 215 elderly persons institutionalized in October 2007 in three nursing homes in Asturias. Socio-demographic, clinical, functional and mental variables were collected through a predefined study protocol., Results: A total of 215 elderly individuals were included in the study (mean +/- standard deviation [SD] 81.2+/-10.2 years, 70.2% women). Barthel Index scores were 50.63+/-37.43, Mini-Mental State Examination (MMSE) scores were 14.71+/-9.73 and Geriatric Depression Scale (GDS) scores were 3.63+/-3.74. Dementia had been diagnosed in 34.4%, the most prevalent cause being Alzheimer's disease (20.9%). Among patients diagnosed with dementia, 45.9% received specific pharmacological treatment for Alzheimer's disease. Among elderly residents who had attended school, 77.8% had MMSE scores below 24 and 32.9% were diagnosed with dementia. Among individuals that had not attended school, 75% had MMSE scores below 18 and 39.6% were diagnosed with dementia., Conclusions: In our study population, approximately 76% of nursing home residents showed some degree of cognitive decline, 1 out of 3 residents had been diagnosed with dementia and about half were receiving specific pharmacological treatment. The results show that approximately 40% of elderly individuals admitted to nursing homes with cognitive impairment lack a clear diagnosis of the syndrome or its cause.

Background: Didanosine enteric-coated capsules (ddI-EC) should be taken under fasting conditions. However, the effect of food on the absorption of ddI-EC may not reduce exposure to the drug., Method: We performed an observational study to assess the effect on virological failure of taking ddI-EC with food. To be included, patients had to have begun their first ddI-EC-containing HAART regimen between June 1, 2001 and June 1, 2003. Primary endpoints were virological failure or discontinuation of the ddI-EC-containing regimen., Results: 668 patients were included (119 patients were naïve, 172 switched from a different regimen, and 377 were part of rescue therapy). 296 patients were taking ddI-EC with food. After 71 weeks of follow-up, 162 discontinued ddI-EC in the fasting group and 120 in the fed group. 46 patients had virological failure (19 without food vs. 27 in the group with food). Adherence to therapy >80% was 79.7%. We fitted a multivariate Cox proportional hazard model and found a significant interaction between ddI-EC intake and adherence. The multivariate model showed that when adherence to HAART was poor (<80% of prescribed pills) taking ddI-EC with food significantly increased the risk of virological failure (hazard ratio [HR] 8.32, 95% CI 1.67-41.65), but this disappeared when adherence was 80%-95% (HR 0.27, 95% CI 0.04-1.53) or >95% (HR 0.57, 95% CI 0.12-2.77)., Conclusion: When adherence is good (>80% of the prescribed doses), ddI-EC can be administered with food without an increase in virological failure or HAART discontinuation.

A survey-based comparative study was conducted to evaluate the changes on the prostate pathology in two male populations separated by a time interval of two years (1st and 3rd Week of Prostate Health). A total of 2056 respondents in the 1st Week, and 2126 in the 3rd Week were evaluated. The questionnaire included questions relative to prostate awareness, impact of urinary complaints on daily like activities, Spanish validated IPSS and selective questions for prostate patients. The comparison between both surveys disclosed visits to the urologist at earlier age and longer-standing symptoms. The most prevalent symptoms continue to be decreased calibre of the urinary stream, pollakiuria and urgency. IPSS/L and IPSS/age ratios remained unchanged. There was increased number of visits by mildly symptomatic patients (IPSS < 8), increased periodical revisions, and in the number of patients seen and treated by the urologist. A significant approximation to the diagnostic testing criteria established by the WHO for BPH was demonstrated. The number of patients who received treatment raised and there was also a significant improvement in the outcome. Comparative populational studies could allow to assess changes in the awareness status of the prostate, changes in symptomatic levels and quality of life of the population requesting health care, as well as changes in the diagnostic and therapeutical schemes in patients suspected of having BPH.

Objectives: to determine the value of percutaneous liver biopsy (PLB) in the diagnosis of fever of unknown origin (FUO) in HIV-infected patients and establish a prediction model for its usefulness to enable diagnosis of FUO in these patients to be standardized., Methods: a total of 58 HIV-infected patients who underwent PLB for the evaluation of FUO were studied at 'Carlos Haya' Hospital in Malaga, Spain. The patients were classified into three groups, according to the results of the PLB: (a) diagnostic PLB (when a definitive diagnosis was obtained); (b) helpful PLB (the tissue sample showed suggestive, but not definitive, findings); and (c) normal or non-specific PLB (no contribution to diagnosis, the findings being normal or irrelevant). Multivariate analysis was made to establish a prediction model for the diagnostic usefulness of PLB, calculating the positive (PPV) and negative (NPV) predictive values., Results: PLB was carried out in 58 HIV-infected patients during diagnosis of FUO. Risk factors for HIV infection included intravenous drug use (72.4%), homosexual or bisexual activities (12.1%), and heterosexual transmission (15.5%). Fifty-two out of 58 patients (89.6%) had previous AIDS-defining illnesses. The mean CD4 lymphocyte count +/-SD was 56.4+/-80.9/mm3. The mean duration of fever was 43 days. Diagnosis could be established in 51 (87.9%) patients, with tuberculosis (50%) and leishmaniasis (20.7%) being the most common. The PLB was diagnostic in 25 cases (43.1%), helpful in 13 (22.4%), and normal or non-specific in the remaining 20 (34.5%). Biopsy-associated complications occurred in two cases. The presence of hepatomegaly or splenomegaly were the most useful factors in predicting the usefulness of the PLB, with a PPV of 86.1% and NPV of 68.2%. In patients with tuberculosis, an increased alkaline phosphatase and hepatomegaly had a PPV of 86.4% and a NPV of 71.4%., Conclusions: PLB is a useful technique for the diagnosis of FUO in HIV-infected persons. Early PLB should be considered in those patients with hepatosplenomegaly and increased alkaline phosphatase levels.

Objective: To analyze the clinical features, yield of the diagnostic techniques, and therapeutic response of HIV-associated visceral leishmaniasis (VL), and compare the initial episodes to the relapses., Methods: Forty-one episodes of leishmaniasis visceral, diagnosed in 31 HIV-positive patients between 1st February 1992 and 31st January 1996 were reviewed., Results: The prevalence of VL in HIV-positive patients in our center was 4.2%. Fifty-eight percent of the patients had AIDS prior to the diagnosis of VL. Fever was more frequent in the initial episodes than in the relapses (90.3% versus 60%; p < 0.05; OR: 6.2; IC 95%: 0.8-51.5), splenomegaly was more frequent in the relapses (100% versus 71%; p = 0.05). The diagnostic delay was longer in the initial episodes (27.2 +/- 22.7 versus 5 +/- 4.8 days; p < 0.05). The diagnostic yield of bone marrow biopsy was 82.1%, of liver biopsy 72.7% and of splenic fine-needle aspiration 87.5%. The indirect immunofluorescence test for Leishmania antibodies was positive in 5.9% of cases. Therapeutic failure occurred in 47.6% of patients treated with antimonials and 3.3% of patients treated with amphotericin B. Those patients who received secondary prophylaxis had less relapses than those who did not (17.6% versus 66.7%; p < 0.05; OR: 0.11; IC 95%: 0.01-1.28). Of the 31 patients, twenty-six (83.8%) died, and in none of them was the cause of the death directly related to LV., Conclusion: HIV-associated VL manifests clinically in a similar fashion to the immunocompetent's disease. It appears in advanced immunosuppression phases, behaving like other AIDS-defining illnesses. In spite of a good therapeutic response the relapse rate is high.

All patients diagnosed of brucellosis in 4 regional hospitals during a period of nine years were reviewed, in an attempt to evaluate the efficacy of different antimicrobic regimens and also the clinical features. Evolution and complications of brucellar sacroiliitis. Of a total of 548 patients, 12% had been diagnosed of sacroiliitis and, of theme, 49 had complete data available with efficacy of different treatments, the time elapsed until fever and pain ceased was evaluated, together with initial therapeutic failures, relapses and length of hospital stay. Brucellar sacroiliitis is the most frequent osteoarthral complication of Brucella sp. in our setting. Keeping an stable incidence. It is predominant among young male (82%) population (mean age 25 +/- 12 years). The illness evolution is acute and less frequently subacute with a evolution mean-time before referral of 38 +/- 44 days (minimum 4 days, maximum 180 days). Fever (81%) and pain on gluteus and low lumbar localizations (100%) are the more frequent clinical features. Time elapsed until pain ceased was longer with doxycycline plus rifampicin (68 +/- 86) than with doxycycline plus streptomycin (28 +/- 43) (less than 0.05) and length of hospital stay was also longer with said treatment (p less than 0.05). There were no differences concerning time frame until fever ceased, initial therapy failures and relapses. Sequelae are infrequent and consist in persistency of pain. In resume response to treatment with usual regimens, doxycycline plus streptomycin of doxycycline rifampicin is good, being however time elapsed until pain ceases of mean length in hospital stay shorter in the group receiving doxycycline plus streptomycin. Control studies to confirm these data are need.

The study population consisted of 832 premenarcheal girls. Vaginal cultures are performed on 40 premenarcheal girls suffering from vulvovaginitis. All were less than 7 years old. This patients were seen in primary cares. In 23 cases (57.5%) E. coli was isolated, Enterococcus (30%), mixed flora (10%) and G. vaginalis (2.5%). Common clinical characteristics were pruritus (97.5%), vaginal discharge (67.5%). Dysuria and abdominal pain constituted accompanying symptoms. Only in one case masturbation was observed.
