[Psychosomatic symptoms as an expression of the deterioration of the health-related quality of life in adolescents]. / Síntomas psicosomáticos como expresión del deterioro de la calidad de vida relacionada con la salud en adolescentes.

AIM: To analyze, in a population of adolescents in school, the relationship between psychosomatic symptoms and the perception of health-related quality of life (HRQoL), differentiating by gender and age group. DESIGN: Transversal study. LOCATION: Five Secondary Schools. PARTICIPANTS: Eight hundred and forty four adolescents between the ages of 15 and 18 in secondary school. MAIN MEASUREMENTS: HRQoL using KIDSCREEN-52 and psychosomatic symptoms with the psychosomatic problems scale (PSP). RESULTS: Girls and adolescents aged 17-18 years presented significantly higher psychosomatic symptoms, both groups also scored worse in all dimensions of HRQoL, although only the dimensions related to physical and mental wellness, mood and stress reached significance. All psychosomatic symptoms were inversely associated with the ten dimensions of KIDSCREEN-52. The regression models showed that sadness, concentrating difficulties and sleeping difficulties were the predictors of worse HRQoL in both sexes and age groups and these variables explained between 30 and 41% of the HRQoL variance of the adolescents. CONCLUSIONS: Psychosomatic symptoms are frequent especially in girls and in older adolescents and predictors of worse HRQoL. It is important to distinguish them from medical conditions to avoid unnecessary interventions. As expressions of emotional discomfort they must be evaluated and treated in an integral way because they interfere with daily life and increase the vulnerability proper of adolescence.

Characterisation of genetic structure of the Mayan population in Guatemala by autosomal STR analysis.

BACKGROUND: Currently, the Guatemalan population comprises genetically isolated groups due to geographic, linguistic and cultural factors. For example, Mayan groups within the Guatemala population have preserved their own language, culture and religion. These practices have limited genetic admixture and have maintained the genetic identity of Mayan populations. AIM: This study is designed to define the genetic structure of the Mayan-Guatemalan groups Kaqchiquel, K'iche', Mam and Q'eqchi' through autosomal short tandem repeat (STR) polymorphisms and to analyse the genetic relationships between them and with other Mayan groups. SUBJECTS AND METHODS: Fifteen STR polymorphisms were analysed in 200 unrelated donors belonging to the Kaqchiquel (n = 50), K'iche' (n = 50), Mam (n = 50) and Q'eqchi' (n = 50) groups living in Guatemala. Genetic distance, non-metric MDS and AMOVA were used to analyse the genetic relationships between population groups. RESULTS: Within the Mayan population, the STRs D18S51 and FGA were the most informative markers and TH01 was the least informative. AMOVA and genetic distance analyses showed that the Guatemalan-Native American populations are highly similar to Mayan populations living in Mexico. CONCLUSIONS: The Mayan populations from Guatemala and other Native American groups display high genetic homogeneity. Genetic relationships between these groups are more affected by cultural and linguistic factors than geographical and local flow. This study represents one of the first steps in understanding Mayan-Guatemalan populations, the associations between their sub-populations and differences in gene diversity with other populations. This article also demonstrates that the Mestizo population shares most of its ancestral genetic components with the Guatemala Mayan populations.

The role of plasma IDO activity as a diagnostic marker of patients with colorectal cancer.

High levels of indoleamine 2,3-dioxygenase (IDO) are involved in tumour escape mechanisms. The aim of this study is the evaluation of L-kynurenine of plasma as marker of diagnostic and prognostic in patients with colorectal cancer. The study included 78 patients with colorectal cancer, of whom 15 % were in stage I/II, 30 % in stage III, and 55 % in stage IV, and was compared with a control group of 70 healthy subjects. The receiver operating characteristic (ROC) curve analysis showed an area under the curve of 0.917, with a specificity of 100 % and with a sensitivity to detect cancer of the colon of 85.2 %, taking 1.83 µM as a cut-off point. The overall survival analysis also indicated that patients with low levels of L-kynurenine in plasma increased survival rate after 45 months of follow-up (P = 0.032). These results show that the plasma levels of L-kynurenine could be a good biomarker to differentiate individuals with colorectal cancer from healthy individuals.

Rationale and design of a randomized, double-blind, placebo controlled multicenter trial to study efficacy, security, and long term effects of intermittent repeated levosimendan administration in patients with advanced heart failure: LAICA study.

BACKGROUND: Advanced heart failure (HF) is associated with high morbidity and mortality; it represents a major burden for the health system. Episodes of acute decompensation requiring frequent and prolonged hospitalizations account for most HF-related expenditure. Inotropic drugs are frequently used during hospitalization, but rarely in out-patients. The LAICA clinical trial aims to evaluate the effectiveness and safety of monthly levosimendan infusion in patients with advanced HF to reduce the incidence of hospital admissions for acute HF decompensation. METHODS: The LAICA study is a multicenter, prospective, randomized, double-blind, placebo-controlled, parallel group trial. It aims to recruit 213 out-patients, randomized to receive either a 24-h infusion of levosimendan at 0.1 µg/kg/min dose, without a loading dose, every 30 days, or placebo. RESULTS: The main objective is to assess the incidence of admission for acute HF worsening during 12 months. Secondarily, the trial will assess the effect of intermittent levosimendan on other variables, including the time in days from randomization to first admission for acute HF worsening, mortality and serious adverse events. CONCLUSIONS: The LAICA trial results could allow confirmation of the usefulness of intermittent levosimendan infusion in reducing the rate of hospitalization for HF worsening in advanced HF outpatients.

Cerebral and cerebellar pseudoatrophy associated with valproic acid. Report of three pediatric cases. / Pseudoatrofia cerebral y cerebelosa asociada a ácido valproico. Descripción de tres casos pediátricos.

INTRODUCTION: Cerebral and cerebellar pseudoatrophy is a rare adverse effect of valproic acid (VPA) that we need to be aware of, due to its diagnostic and therapeutic implications. CASE REPORT: We report three cases of children between 5 and 9 years old, with epilepsy and previous normal brain magnetic resonance imaging, who were taking the drug at correct doses. Pseudoatrophy manifests subacutely with symptoms and images of cerebral and/or cerebellar atrophy, reversible after drug withdrawal. DISCUSSION AND CONCLUSIONS: This is a type of VPA-related encephalopathy, different from dose-dependent toxic encephalopathy, hyperammonaemic encephalopathy or encephalopathy related to liver failure. In children, it causes cognitive, motor, mood and behavioral deterioration, and may be accompanied by epileptic decompensation. Withdrawing the drug leads to complete clinical-radiological recovery, and reducing the dose leads to improvement.

La retirada del fármaco conlleva una recuperación completa clinicorradiológica, y la disminución de dosis, una mejoría.

Genetic identification of missing persons: DNA analysis of human remains and compromised samples.

Human identification has made great strides over the past 2 decades due to the advent of DNA typing. Forensic DNA typing provides genetic data from a variety of materials and individuals, and is applied to many important issues that confront society. Part of the success of DNA typing is the generation of DNA databases to help identify missing persons and to develop investigative leads to assist law enforcement. DNA databases house DNA profiles from convicted felons (and in some jurisdictions arrestees), forensic evidence, human remains, and direct and family reference samples of missing persons. These databases are essential tools, which are becoming quite large (for example the US Database contains 10 million profiles). The scientific, governmental and private communities continue to work together to standardize genetic markers for more effective worldwide data sharing, to develop and validate robust DNA typing kits that contain the reagents necessary to type core identity genetic markers, to develop technologies that facilitate a number of analytical processes and to develop policies to make human identity testing more effective. Indeed, DNA typing is integral to resolving a number of serious criminal and civil concerns, such as solving missing person cases and identifying victims of mass disasters and children who may have been victims of human trafficking, and provides information for historical studies. As more refined capabilities are still required, novel approaches are being sought, such as genetic testing by next-generation sequencing, mass spectrometry, chip arrays and pyrosequencing. Single nucleotide polymorphisms offer the potential to analyze severely compromised biological samples, to determine the facial phenotype of decomposed human remains and to predict the bioancestry of individuals, a new focus in analyzing this type of markers.

Cancer chemotherapy reduces plasma total polyphenols and total antioxidants capacity in colorectal cancer patients.

Our aim was to investigate the effect of chemotherapy on plasma total antioxidant capacity and polyphenols in patients with colon cancer. Plasma samples were collected from 70 CRC patients under chemotherapy treatment, and 15 non-treated patients. The control group included 71 healthy individuals. Plasma ABTS and FRAP were measured as biomarkers of antioxidant total capacity and the total phenols as an indicator to determine the polyphenols levels in plasma. Treatment with chemotherapy protocols resulted in a significant decrease of ABTS (-24 %, p < 0.048), FRAP (-15 %, p < 0.046) and polyphenols (-46 %, p < 0.05) compared with the values of those not treated. The total antioxidant capacity was significantly lower (-18 % for ABTS and -12 % for FRAP) in patients with metastasis as compared with patients without metastasis. The plasma total phenols, were also decreased (-16 %, p = 0.005) in metastasis patients. The patients with colorectal cancer have decreased total antioxidant capacity and the values are lower in patients treated with chemotherapy. Furthermore, CEA tumor marker levels are associated with a lower plasma total antioxidant capacity, and therefore with the progress and development of the disease.

Paediatric adverse drug reactions reported to the Spanish Pharmacovigilance System from 2004 to 2009.

PURPOSE: This study was conducted to evaluate relevant new information about ADRs reported in the Spanish paediatric population over a 6-year period. METHODS: Adverse drug reactions (ADRs) for individuals aged 0-17 years reported to the Spanish Pharmacovigilance System from 2004 to 2009 were analysed with respect to time, age and sex, category of ADR [System Organ Class (SOC)], seriousness, suspected medicines [level 2 of the Anatomical Therapeutic Chemical (ATC) Classification System] and type of reporter. RESULTS: In total, 4,279 ADR reports corresponding to 8,196 ADRs were analysed, approximately two ADRs per report. The rate of paediatric ADR reports in 2009 was 165 per million, of which nearly half (46 %) were for children (age group 2-11 years). Similar total numbers of ADRs were reported for boys and girls. The most frequent ADRs reported were from the following SOCs: general disorders and administration site conditions (34 %); skin and subcutaneous tissue disorders (15 %); nervous system disorders (14 %). Reports encompassed medicines from various ATC groups: vaccines and anti-infectives for systemic use (67 %); nervous system (9 %); respiratory system (9 %). On average, 37 % of ADRs were classified as serious. There were 33 fatal ADRs, and 35 % of the paediatric population associated with the ADR notifications required hospitalization or extended hospital stay. CONCLUSIONS: In Spain, ADR reporting rate in the paediatric population has increased since 2004. The proportion of suspected ADR reports related to vaccines was predominant, which highlights the important role played by nurses. ADR notification of congenital malformations in newborn infants highlights the need for joint action between the Spanish System of Pharmacovigilance of Medicines for Human Use (SEFV-H) and paediatricians, obstetricians and gynaecologists. The publication of safety reports by regulatory agencies is determinant for the increased number of ADR notifications.

Concentration-Dependent Protection by Ethanol Extract of Propolis against γ-Ray-Induced Chromosome Damage in Human Blood Lymphocytes.

Radioprotection with natural products may be relevant to the mitigation of ionizing radiation-induced damage in mammalian systems; in this sense, propolis extracts have shown effects such as antioxidant, antitumoral, anti-inflammatory, and immunostimulant. We report for the first time a cytogenetic study to evaluate the radioprotective effect, in vitro, of propolis against radiation-induced chromosomal damage. Lymphocytes were cultured with increasing concentrations of ethanol extract of propolis (EEP), including 20, 40, 120, 250, 500, 750, 1000, and 2000 µg mL(-1) and then exposed to 2 Gy γ-rays. A significant and concentration-dependent decrease is observed in the frequency of chromosome aberrations in samples treated with EEP. The protection against the formation of dicentrics was concentration-dependent, with a maximum protection at 120 µg mL(-1) of EEP. The observed frequency of dicentrics is described as negative exponential function, indicating that the maximum protectible fraction of dicentrics is approximately 44%. Free radical scavenging and antioxidant activities are the mechanisms that these substances use to protect cells from ionizing radiation.

[Profile of drug use in adolescents. Protective factors]. / Perfil de consumo de drogas en adolescentes. Factores protectores.

OBJECTIVE: To determine the patterns of drug use in an adolescent population and to analyse the role of personal and social protective factors in alcohol consumption. MATERIAL AND METHODS: A descriptive cross-sectional study was carried out in five secondary schools in the city of Cuenca (Spain) in the period 2015-2016. The groups were randomly selected (3rd - 4th GCSE and 1st - 2nd GCE), with a total of 844 students giving their consent. A self-administered questionnaire was used, which included sociodemographic variables, consumption data, CD-RISC 10 scale to evaluate resilience, and KIDSCREEN-52 questionnaire to measure individual and social aspects associated with health-related quality of life in adolescents. Descriptive bivariate and multivariate analyses were performed. RESULTS: Just over half (55.7%) of the pupils selected were girls, and the mean age was 16.3±1.01 years. The pupils began consumption when they became 13-14 years old. The percentages of habitual consumption were 70.9% for alcohol, 26.4% for tobacco, and 14.2% for cannabis. Multiple drug use was also found in 35%. The regression model for alcohol showed that non-consumers showed better values in emotional moods, self-perception, relationships with their parents, and their school environment. CONCLUSIONS: Adolescents start using drugs, especially cannabis, at an earlier age. Availability and the perception of low-risk make alcohol the most widespread drug. Actions aimed at fostering emotional well-being and family support provides security for adolescents, as well as the resources that help them overcome the pressures of the group.

Metformin-associated hyperlactacidaemia acidosis: Diagnosis rate in standard clinical practice and its relationship with renal failure. / Acidosis con hiperlactacidemia por metformina: frecuencia de su diagnóstico en la práctica clínica habitual y relación con la insuficiencia renal.

BACKGROUND AND OBJECTIVES: Observational study on the difference between the number of cases of acidosis with hyperlactacidaemia suspected of being caused by metformin diagnosed in standard clinical practice and the incidence of this condition according to the datasheet. The study also explored the relationship between renal function and metformin-associated hyperlactacidaemia acidosis. PATIENTS: We identified cases of acidosis between 2013 and 2014 by analysing the minimum basic data set and laboratory requests. We selected patients who presented venous lactate levels >2.7 mmol/L at the time they were treated and for whom the use of outpatient metformin was confirmed. The causal relationship with metformin was independently evaluated by several researchers. The incident cases were calculated based on the number of patients who had been dispensed a drug containing metformin during the same period in the study area. RESULTS: We identified 476 cases of acidosis. Metformin was suspected of causing the condition of acidosis with hyperlactacidaemia in 20 of these cases, which represents an incidence rate of 6.57/10,000 patients. Eighty-five percent of the cases presented acute renal failure. CONCLUSIONS: The apparent incidence of acidosis with hyperlactacidaemia in patients treated with metformin is greater than that established in the datasheet (<1/10,000). The onset of metformin-associated hyperlactacidaemia acidosis is related to acute renal impairment.

Prevalence and associated risk factors of latent tuberculosis infection in a Spanish prison.

AIM: To determine the prevalence of latent tuberculosis infection (LTI) in a Spanish prison, analyze the main sociodemographic and clinical variables associated with this condition and estimate the percentage of individuals with LTI who have received chemoprophylactic treatment. MATERIALS AND METHODS: Cross-sectional study including inmates hosted in the Madrid VI Prison on 16/07/2016. Exclusion criteria: history of tuberculosis; non-updated tuberculin test according to the Tuberculosis Prevention and Control Program in Prisons protocol. Information of the variables was collected from SANIT and SIP programs, and by checking the clinical records of inmates. Description of the participant population and comparison between the frequency of distribution of the independent variables in LTI present and absent groups were performed, the last calculating the p value with Ji2 and Mann-Whitney U tests. Bivariate and multivariate analysis have been carried out with a logistic regression model. RESULTS: 936 individuals have been included. The prevalence of LTI in prison is 54.6%. This condition has been linked to the sociodemographic variables age, sex and nationality of origin, being age the one that has shown the strongest association. Among the other factors analyzed, only HCV infection behaves as a predictor of LTI. 30.3% of the individuals with LTI have completed or are receiving chemoprophylactic treatment in the moment of the study. DISCUSSION: LTI prevalence is high in the Spanish current prison population. The results of the study emphasize the relevance of the LTI screening in the prison setting, specially among high risk groups, and point out the need of a greater effort in the indication and completion of the chemoprophylactic treatment.

Median raphe cysts in men. Presentation of our experience and literature review. / Quistes de rafe medio en el varón. Presentación de nuestra experiencia y revisión de la literatura.

OBJECTIVES: To present our experience with the diagnosis and treatment of median raphe cysts treated in our department in the last 25years. MATERIAL AND METHOD: We conducted a retrospective study of 28men with median raphe cysts who underwent surgery in our department from June 1990 to March 2015. We analysed the age of presentation, reason for consultation, clinical manifestations, histological findings, treatment and outcome after exeresis. RESULTS: The majority of the patients (22; 79%) were asymptomatic and consulted for the aesthetic defect. Four cases (14%) presented urinary abnormalities, and 2 cases (7%) reported discomfort during sexual intercourse. In all cases, the treatment consisted of surgical extirpation of the cysts, with excellent aesthetic and functional results and no lesion recurrence in any of the patients during a mean follow-up of more than 10years. The most common histological type was the transitional cell type in 15 cases (54%), followed by the mixed type (transitional and squamous) in 11 cases (39%). One case (6%) was pure squamous type, and in another case (6%) the epithelium was glandular. CONCLUSIONS: Median raphe cysts are an uncommon type of disembryoplasia that can occur in any location of the median raphe, from the balanic meatus to the edges of the anus. These cysts are generally asymptomatic and their treatment of choice is surgical extirpation.

Circulation of a novel human respiratory syncytial virus Group B genotype during the 2014-2015 season in Catalonia (Spain).

Human respiratory syncytial virus (HRSV) is one of the most common viral aetiological agents in the youngest population. In the present study a novel HRSV-B BA genotype is first described based on the phylogenetic analysis of the coding hypervariable region 2 sequences of G protein from strains detected during the 2014-2015 season. Among all strains detected in the last season, 44% belonged to this new genotype. Therefore, it highlights the importance of a continuous HRSV surveillance to monitor the emergence and spread of new genotypes or variants with genetic changes that may affect antigenic and tropism features.

Rapid and steady-state amino acid transport in perfused human fibroblasts and colon adenocarcinoma cells: effects of methotrexate.

Initial and steady-state uptakes of serine and phenylalanine by human fibroblasts and human colon tumour cells were studied applying a double isotope dilution technique to perfused populations of cultivated cells retained on microcarrier beads. This new method permits the differentiation of the unidirectional transport parameters and can also distinguish between membrane-associated processes and independently intracellular events in isolated cells. High initial L-serine uptake values in colon adenocarcinoma cells became negative under steady-state conditions. To determine if the observed negative L-serine uptake was produced by the rapid efflux of intracellular L-[3H]serine, the cells were treated with methotrexate (MTX) (an inhibitor of cytosolic dihydrofolate reductase). The modified curve of L-[3H]serine uptake after MTX treatment suggests that, under these experimental conditions, net serine transport is non concentrative in colon tumour cells and could be modulated by the rate of intracellular serine metabolism; it also suggests that MTX does not directly affect serine transport in perfused human colon adenocarcinoma cells. Initial and steady-state uptakes of phenylalanine were high in both fibroblasts and tumour cells and were unaffected by MTX treatment.
