    Lung cancer (LC) is the leading cause of cancer deaths, and chronic obstructive pulmonary disease (COPD) can increase LC risk. Metallomics may provide insights into both of these tobaccorelated diseases and their shared etiology. We conducted an observational study of 191 human serum samples, including those of healthy controls, LC patients, COPD patients, and patients with both COPD and LC.We found 18 elements (V, Al, As, Mn, Co, Cu, Zn, Cd, Se,W, Mo, Sb, Pb, Tl, Cr, Mg, Ni, and U) in these samples. In addition, we evaluated the elemental profiles of COPD cases of varying severity. The ratios and associations between the elements were also studied as possible signatures of the diseases. COPD severity and LC have a significant impact on the elemental composition of human serum. The severity of COPD was found to reduce the serum concentrations of As, Cd, and Tl and increased the serum concentrations of Mn and Sb compared with healthy control samples, while LC was found to increase Al, As, Mn, and Pb concentrations. This study provides new insights into the effects of LC and COPD on the human serum elemental profile that will pave the way for the potential use of elements as biomarkers for diagnosis and prognosis. It also sheds light on the potential link between the two diseases, i.e., the evolution of COPD to LC.This work has been supported by the project "Heteroatom-tagged proteomics and metabolomics to study lung cancer.

    ResumenAntecedentesDesde 1980 la terapia de neuroestimulación sacra ha demostrado ser una terapia válida y alternativa en el manejo de los trastornos miccionales por patología del tracto urinario bajo, siendo sus principales indicaciones la retención urinaria idiopática, la incontinencia de urgencia y la incontinencia fecal. En nuestro país sigue siendo una terapia novedosa y no se cuenta aún con estudios que evalúen esta eficacia en términos de calidad de vida o con parámetros cuantitativos.Objetivo del estudioEstablecer la eficacia de la terapia de neuroestimulación sacra tipo InterStim, Medtronic®, en el manejo de los pacientes con trastornos de vaciamiento vesical, efectuando un análisis urodinámico y de la calidad de vida comparativo previo y posterior al tratamiento, determinando los volúmenes miccionales, los períodos de incontinencia, la satisfacción del paciente y la calidad de vida.Material y métodosDesde enero de 2010 hasta junio de 2013, en el Hospital Central Militar se realizó evaluación urodinámica y comparativa de la calidad de vida mediante el empleo del instrumento SF-36 v2 (versión mexicana) e ICIQSF, en los pacientes que presentaron trastorno de vaciamiento vesical de etiología no obstructiva y que fueron refractarios a tratamiento médico.ResultadosSe incluyeron 10 pacientes en el estudio, bajo los siguientes diagnósticos: disinergia detrusor-esfínter, vejiga hiperactiva y retención urinaria no obstructiva, ubicados por género (2 masculinos y 8 femeninos). En la totalidad de los pacientes se presentó mejoría del 50% o superior durante la fase de prueba de la terapia de neuroestimulación, y se colocó fase definitiva con los siguientes resultados: se obtuvieron resultados equivalentes al 50-65% de mejoría en los parámetros cualitativos de función física, función social y rol emocional, así como en las variables cuantitativas de volumen de vaciamiento, eficacia de vaciamiento y disminución de los períodos de incontinencia.DiscusiónComo se ha establecido a nivel de la literatura mundial, nuestros resultados fueron similares en el efecto benéfico y la eficacia en la calidad de vida e incontinencia urinaria, respectivamente, y se reportan porcentajes de éxito mayores al 50% en el cese total de los episodios de incontinencia.ConclusionesLa neuromodulación mediante la estimulación del nervio sacro es una forma exitosa de tratamiento en los trastornos de vaciamiento vesical de etiología no obstructiva y refractaria al tratamiento médico, es segura, mínimamente invasiva y de fácil aplicación, y mejora la calidad de vida de los pacientes. Sin embargo, es necesario realizar estudios aleatorizados y que consideren parámetros objetivos (urodinámicos), así como las complicaciones posibles a mediano y largo plazo en este tipo de terapia.AbstractBackgroundSince 1980, sacral neuromodulation therapy has been shown to be a valid alternative therapy in the management of urinary disorders due to lower urinary tract pathology, and its primary indications are: idiopathic urinary retention, urge incontinence, and fecal incontinence. It is still considered a novel therapy in Mexico and there are no studies using quantitative parameters that evaluate its efficacy in terms of quality of life.AimsTo establish the efficacy of the Medtronic InterStim® sacral neuromodulation therapy in the management of patients with bladder voiding disorders through urodynamic and quality of life analyses before and after treatment. Urine volume, periods of incontinence, patient satisfaction, and quality of life were determined.MethodsA comparative urodynamic and quality of life evaluation was carried out using the SF-36 v2 (Mexican version) and the ICIQSF instruments on patients presenting with nonobstructive bladder voiding disorders that were refractory to medical treatment.ResultsTen patients with the following diagnoses were included in the study: detrusor sphincter dyssynergia, overactive bladder, and nonobstructive urinary retention. Two of the patients were men and 8 were women. There was a 50% or greater improvement in all 10 patients during the test phase of the neuromodulation therapy and the definitive placement phase produced the following results: a 50-65% improvement in the qualitative parameters of physical function, social function, and emotional role, as well as in the quantitative variables of voiding volume, voiding efficacy, and reduced periods of incontinence.DiscussionOur results were similar to those established in the international literature in relation to the beneficial effect on quality of life and efficacy in urinary incontinence management; the literature reports success percentages in the complete cessation of incontinence episodes at above 50%.ConclusionsNeuromodulation through sacral nerve stimulation is a successful form of treatment of nonobstructive and medical treatment-refractory bladder voiding disorders. It is safe, minimally invasive, and easy to apply and it improves patient quality of life. Nevertheless, further randomized studies on this type of therapy need to be conducted that take into account objective parameters (urodynamics) and possible medium and long-term complications

    OBJECTIVE: To generate normative data for the Trail Making Test (TMT) in Spanish-speaking pediatric populations. METHOD: The sample consisted of 3,337 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the TMT as part of a larger neuropsychological battery. The TMT-A and TMT-B scores were normed using multiple linear regressions and standard deviations of residual values. Age, age2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. RESULTS: The final multiple linear regression models showed main effects for age on both scores, such that as children needed less time to complete the test while they become older. TMT-A scores were affected by age2 for all countries except, Cuba, Guatemala, and Puerto. TMT-B scores were affected by age2 for all countries except, Guatemala and Puerto Rico. Models indicated that children whose parent(s) had a MLPE >12 years of education needed less time to complete the test compared to children whose parent(s) had a MLPE ≤12 years for Mexico and Paraguay in TMT-A scores; and Ecuador, Mexico, Paraguay, and Spain for TMT-B scores. Sex affected TMT-A scores for Chile, Cuba, Mexico, and Peru, in that boys needed less time to complete the test than girls. Sex did not affect TMT-B scores. CONCLUSIONS: This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate approach to interpret the TMT in pediatric populations

    Evidence for a mixed mass composition at the `ankle' in the cosmic-ray spectrum

    We report a first measurement for ultra-high energy cosmic rays of the correlation between the depth of shower maximum and the signal in the water Cherenkov stations of air-showers registered simultaneously by the fluorescence and the surface detectors of the Pierre Auger Observatory. Such a correlation measurement is a unique feature of a hybrid air-shower observatory with sensitivity to both the electromagnetic and muonic components. It allows an accurate determination of the spread of primary masses in the cosmic-ray flux. Up till now, constraints on the spread of primary masses have been dominated by systematic uncertainties. The present correlation measurement is not affected by systematics in the measurement of the depth of shower maximum or the signal in the water Cherenkov stations. The analysis relies on general characteristics of air showers and is thus robust also with respect to uncertainties in hadronic event generators. The observed correlation in the energy range around the `ankle' at lg(E/eV)=18.519.0\lg(E/{\rm eV})=18.5-19.0 differs significantly from expectations for pure primary cosmic-ray compositions. A light composition made up of proton and helium only is equally inconsistent with observations. The data are explained well by a mixed composition including nuclei with mass A>4A > 4. Scenarios such as the proton dip model, with almost pure compositions, are thus disfavoured as the sole explanation of the ultrahigh-energy cosmic-ray flux at Earth.Comment: Published version.

    Diet quality index as a predictor of treatment efficacy in overweight and obese adolescents: The EVASYON study

    Get PDF
    Background & aim: A diet quality index (DQI) is a tool that provides an overall score of an individual''s dietary intake when assessing compliance with food-based dietary guidelines. A number of DQIs have emerged, albeit their associations with health-related outcomes are debated. The aim of the present study was to assess whether adherence to dietary intervention, and the overall quality of the diet, can predict body composition changes. Methods: To this purpose, overweight/obese adolescents (n = 117, aged: 13–16 years; 51 males, 66 females) were recruited into a multi-component (diet, physical activity and psychological support) family-based group treatment programme. We measured the adolescents’ compliance and body composition at baseline and after 2 months (intensive phase) and 13 months (extensive phase) of follow-up. Also, at baseline, after 6 months, and at the end of follow-up we calculated the DQI. Results: Global compliance with the dietary intervention was 37.4% during the intensive phase, and 14.3% during the extensive phase. Physical activity compliance was 94.1% at 2-months and 34.7% at 13months and psychological support compliance were growing over the intervention period (10.3% intensive phase and 45.3% during extensive phase). Adolescents complying with the meal frequency criteria at the end of the extensive phase had greater reductions in FMI z-scores than those did not complying (Cohen''s d = 0.53). A statistically significant association was observed with the diet quality index. DQI-A variation explained 98.1% of BMI z-score changes and 95.1% of FMI changes. Conclusions: We conclude that assessment of changes in diet quality could be a useful tool in predicting body composition changes in obese adolescents involved in a diet and physical activity intervention programme backed-up by psychological and family support

    RICORS2040 : The need for collaborative research in chronic kidney disease

    Get PDF
    Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is 'solved' by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020-2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true
