Biomechanical models of in vitro constructs for spinopelvic osteosynthesis.

Spinopelvic lesions are the result of high-energy vertical trauma with axial skeletal overload where the spine impacts onto the sacrum, dissociating the lumbar spine from the pelvis. Therefore, lumbopelvic instrumentations are aimed to counteract these vertical forces, although various biomechanical aspects of the combinations of different constructs (with or without iliosacral screws) or the number of lumbar fixation levels (L5 or the combination of L5 with L4) are subject to controversy. The number of patients in each published series is too short, and the nature of the fixation is very different from one article to another, making comparison very difficult. In this paper the methodology for laboratory studies is discussed. The design of the test bench fixture, biomechanical testing protocol and data analysis are very important when inference to the clinical setting is desired.

Ecografía diafragmática perioperatoria en el punto de atención como herramienta de predicción de fallo respiratorio postoperatorio en pacientes de alto riesgo: estudio de viabilidad y serie de casos / Perioperative diaphragm point-of-care ultrasound as a prediction tool of postoperative respiratory failure in high-risk patients: A feasibility study and case series

Introducción: La función muscular respiratoria en el período postoperatorio es clave para determinar si un paciente desarrollará insuficiencia respiratoria postoperatoria (IRP) o no. La IRP ocurre cuando el intercambio de gases no satisface las necesidades metabólicas. La parálisis ipsilateral del hemidiafragma después del bloqueo del plexo braquial interescalénico (BPBI) provoca una reducción aguda de la función muscular respiratoria. Esta reducción no causa IRP cuando el hemidiafragma contralateral genera suficiente intercambio de gases para satisfacer las demandas metabólicas. Objetivos: Estudiar la evolución de la función muscular hemidiafragmática durante el perioperatorio mediante ecografía diafragmática (D-POCUS) y usarlo como una herramienta innovadora de predicción de IRP valorando el hemidiafragma contralateral en caso de que ocurra una parálisis hemidiafragmática aguda. Métodos: Se estudian pacientes considerados de alto riesgo programados para cirugía de hombro con BPBI. Se evalúan ecográficamente ambos hemidiafragmas, antes y después del procedimiento, mediante fracción de acortamiento (FA) y excursión diafragmática (ED). Se registró en URPA los pacientes con IRP. Resultados: En los 6 pacientes estudiados se produjo una reducción significativa de la FA y la ED del hemidiafragma ipsilateral. Solo 1/6 mostró signos de IRP. La evaluación del hemidiafragma contralateral durante el postoperatorio mostró que en los 5 pacientes sin signos de IRP no existieron cambios significativos en la función del hemidiafragma contralateral. El único paciente que mostró una caída de la función hemidiafragmática contralateral fue el único paciente que padeció IRP. Conclusiones: En esta serie de casos D-POCUS permite conocer la función perioperatoria del diafragma en pacientes de alto riesgo. Todos los pacientes sufrieron una reducción de la FA y la excursión hemidiafragmática aguda tras BPBI; sin embargo, estos pacientes no desarrollaron...(AU)

Introduction: Respiratory muscle function in the postoperative period is a key to whether a patient develops Postoperative Respiratory Failure (PRF) or not. PRF occurs when the gas exchange does not meet metabolic needs. Ipsilateral paralysis of the hemidiaphragm after interscalenic brachial plexus block (ISB) causes an acute reduction of respiratory muscle function. This reduction does not cause PRF when the contralateral hemidiaphragm generates enough gas exchange to meet metabolic demands. Objectives: To study the evolution of hemidiaphragmatic muscle function during the perioperative period with diaphragmatic ultrasound (D-POCUS), and use it as an innovative tool to predict PRF, assessing the contralateral hemidiaphragm in the event of acute hemidiaphragm paralysis. Methods: Patients considered high risk, scheduled for shoulder surgery with ISB are studied. Both hemidiaphragms were evaluated by ultrasound, before and after the procedure, measuring Thickening Fraction (TF) and Diaphragmatic Excursion (DE). PACU patients with PRF were registered. Results: There was a significant reduction in the TF and DE of the ipsilateral hemidiaphragm in the six patients studied. Only 1/6 patients showed signs of PRF. The evaluation of the contralateral hemidiaphragm during the postoperative period showed that in the five patients without signs of PRF, there were no significant changes in the function of the contralateral hemidiaphragm. The patient, who showed a reduction in contralateral hemidiaphragm function, was the only one who suffered PRF. Conclusions: In this case series, D-POCUS allows to know the perioperative function of the diaphragm in high-risk patients. All patients suffered an acute reduction of hemidiaphragm function after ISB; however, these patients did not develop PRF when the contralateral hemidiaphragm function was preserved.(AU)

BDNF levels and nigrostriatal degeneration in "drug naïve" Parkinson's disease patients. An "in vivo" study using I-123-FP-CIT SPECT.

INTRODUCTION: Parkinson's Disease (PD) is a common neurodegenerative disorder, characterized by a progressive loss of dopaminergic neurons and whose cause remains unclear. Brain-Derived Neurotrophic factor (BDNF) is a protein involved in dopaminergic cells survival. Previous studies have shown decreased serum BDNF levels in PD patients. AIM AND OBJECTIVES: The aim of the study was to evaluate serum BDNF levels in a group of recently diagnosed non-medicated PD patients and its relationship with the nigrostriatal system degeneration using I-123-FP-CIT. METHODS: 30 recently diagnosed, unmedicated PD patients were included in this study. Serum BDNF levels were measured twice using a sandwich enzyme linked immunoabsorbent assay and compared with levels of 27 unrelated Caucasian healthy adults. A I-123-FP-CIT SPECT was performed in all PD Patients in order to assess the association between serum BDNF levels and I-123-FP CIT uptake in several brain areas using a volumetric semi-automatic method. RESULTS: PD patients showed lower serum BDNF levels (Median = 49.61, IQ range: 43.55 to 61.82) than the controls (Median = 68.82, IQ range: 51.87 to 88.14) (U = 211.00, z = -3.10, p = 0.002). BDNF levels in PD patients correlated with both caudate (Spearman r = 0.58, p = 0.001 for ispilateral and r 0.55, p = 0.002 for contralateral) and putamen (Spearman r = 0.68, p < 0.001 for ipsilateral and r = 0.80, p < 0.001 for contralateral) I-123-FP-CIT uptake ratios. CONCLUSIONS: Serum BDNF levels were lower in recently diagnosed, untreated PD patients compared to controls. These lower levels were significantly correlated with the I-123-FP-CIT uptake ratios.

Water consumption related to different diets in Mediterranean cities.

Providing the sustainable development goals (SDGs) water, food and energy security to cities relies strongly on resource use outside city borders. Many modern cities have recently invested in a sustainable urban water system, and score high in international city rankings regarding water management and direct urban water use. However, these rankings generally neglect external resource use for cities. Here we quantify the water resources related to food consumption in thirteen cities located in Mediterranean countries, by means of the water footprint (WF) concept. These WFs amount from 3277l per capita per day (l/cap/d) to 5789l/cap/d. These amounts are about thirty times higher than their direct urban water use. We additionally analyse the WF of three diet scenarios, based upon a Mediterranean dietary pattern. Many authors identify the Mediterranean diet as cultural heritage, being beneficial for human health and a model for a sustainable food system. The first diet scenario, a healthy Mediterranean diet including meat, leads to WF reductions of -19% to -43%. The second diet scenario (pesco-vegetarian), leads to WF reductions of -28% to -52%. The third diet scenario (vegetarian), leads to WF reductions of -30% to -53%. In other words, if urban citizens want to save water, they need to look at their diets.

Mortalidad prematura cardiovascular y sus costes: 20 años de seguimiento del estudio DRECE / Costs resulting from premature mortality due to cardiovascular causes: a 20-year follow-up of the DRECE study

Objetivos. Las enfermedades cardiovasculares permanecen todavía como la principal causa de muerte en España. El estudio Dieta y Riesgo de Enfermedades Cardiovasculares en España (DRECE) se basa en una cohorte representativa de la población general española en la que se analizan los hábitos nutricionales y de vida estudiando su asociación con los patrones de morbimortalidad. Hemos estimado el impacto, en términos de pérdida de productividad, de la mortalidad prematura atribuida a las enfermedades cardiovasculares. Métodos. La pérdida de productividad atribuida a mortalidad prematura se calculó desde 1991, basándose en los años de vida y de vida laboral potencialmente perdidos. Resultados. Durante el seguimiento de 20años de una cohorte de 4.779 sujetos se produjeron 225 fallecimientos (hombres, 152). El 16% de las defunciones se atribuyó a enfermedades cardiovasculares. Los costes por pérdidas de productividad por mortalidad prematura superaron los 29 millones de euros. De ellos, 4 millones de euros (14% del coste total) se debieron a causas cardiovasculares. Conclusiones. La mortalidad prematura cardiovascular en la cohorte DRECE ha supuesto un importante coste social por pérdidas de productividad laboral (AU)

Objectives. Cardiovascular diseases are still the leading cause of death in Spain. The DRECE study (Diet and Cardiovascular Disease Risk in Spain), based on a representative cohort of the Spanish general population, analyzed nutritional habits and lifestyle and their association with morbidity and mortality patterns. We estimated the impact, in terms of loss of productivity, of premature mortality attributed to cardiovascular diseases. Methods. The loss of productivity attributed to premature mortality was calculated from 1991, based on the potential years of life lost and the potential years of working life lost. Results. During the 20-year follow-up of a cohort of 4779 patients, 225 of these patients died (men, 152). Sixteen percent of the deaths were attributed to cardiovascular disease. The costs due to lost productivity by premature mortality exceeded 29 million euros. Of these, 4 million euros (14% of the total cost) were due to cardiovascular causes. Conclusions. Premature cardiovascular mortality in the DRECE cohort represented a significant social cost due to lost productivity (AU)

Sulphur and oxygen isotope analysis to identify sources of sulphur in gypsum-rich black crusts developed on granites.

We describe the results of sulphur and oxygen isotope analyses used to identify sources of the gypsum present in black crusts that grow on the granite of historical buildings. The crusts were sampled at various locations in and near the city of Vigo (NW Spain) and were analysed for their sulphur content and δ(34)S and δ(18)O isotope ratios. Sampled crusts had δ(34)S values of 7.3‰ to 12.9‰ and δ(18)O values of 6.56‰ to 12.51‰. Sampled as potential sulphur sources were bulk depositions, seawater, foundation, ashlar and construction materials and combustion residues. The results indicated marine and, to a lesser extent, anthropogenic, origins for the sulphur and ruled out the contribution of sub-soil sulphates by capillary rise from building foundations. Isotope analyses would indicate that cement and mortar were enriched in sulphur after their application in buildings. The fact that facade orientation (towards the sea or fossil fuel pollution sources) was correlated with sulphur isotope distribution pointed to various contributions to black crust formation.

Interaction between PARP-1 and HIF-2α in the hypoxic response.

Hypoxia-inducible factors (HIFs) mediate the transcriptional adaptation of hypoxic cells. The extensive transcriptional programm regulated by HIFs involves the induction of genes controlling angiogenesis, cellular metabolism, cell growth, metastasis, apoptosis, extracellular matrix remodeling and others. HIF is a heterodimer of HIF-α and HIF-ß subunits. In addition to HIF-1α, HIF-2α has evolved as an isoform that contributes differently to the hypoxic adaptation by performing non-redundant functions. Poly (ADP-ribose) polymerase-1 (PARP-1) is a nuclear protein involved in the control of DNA repair and gene transcription by modulating chromatin structure and acting as part of gene-specific enhancer/promoter-binding complexes. Previous results have shown that PARP-1 regulates HIF-1 activity. In this study, we focused on the cross-talk between HIF-2α and PARP-1. By using different approaches to suppress PARP-1, we show that HIF-2α mRNA expression, protein levels and HIF-2-dependent gene expression, such as ANGPTL4 and erythropoietin (EPO), are regulated by PARP-1. This regulation occurs at both the transcriptional and post-trancriptional level. We also show a complex formation between HIF-2α with PARP-1. This complex is sensitive to PARP inhibition and seems to protect against the von Hippel-Lindau-dependent HIF-2α degradation. Finally, we show that parp-1(-/-) mice display a significant reduction in the circulating hypoxia-induced EPO levels, number of red cells and hemoglobin concentration. Altogether, these results reveal a complex functional interaction between PARP-1 and the HIF system and suggest that PARP-1 is involved in the fine tuning of the HIF-mediated hypoxic response in vivo.

Serum biochemical markers in drowning: diagnostic efficacy of Strontium and other trace elements.

The aim of our study was to analyse several serum biochemical markers in order to evaluate the discriminant capacity of trace elements individually and jointly in drowning (seawater drowning and freshwater drowning) and their correlation with age, sex, postmortem interval, time in water and concentrations of the trace elements in the drowning medium. Sixty-seven cases of drowning (53 seawater drownings (SWD); 14 freshwater drownings (FWD) and 73 control cases (other asphyxias, n=44, and other causes of death, n=29) were selected according to the scene, cause and circumstances of death, together with autopsy findings. Serum strontium (Sr), magnesium (Mg), sodium (Na), chloride (Cl), calcium (Ca), iron (Fe), urea, creatinine (Cr) and cardiac Troponine T (cTn-T) were measured in the left ventricle (Lv), right ventricle (Rv) and peripheral blood. Lv-Rv differences for each marker and Sr, Mg, Na, Cl, Ca and Fe concentrations in the drowning medium were determinated. Mean concentrations of Sr, Cl and Mg in both ventricles and peripheral serum and Lv-Rv differences and Ca Lv and Na Rv were significantly higher in cases of drowning than for other causes of death. In SWD, Sr, Mg, Ca, Na and Cl were significantly higher in Lv than in Rv as a result of aspirating water. In contrast, haemodilution is evident from the significantly higher levels of Fe and urea in Rv than in Lv in cases of SWD, and from the higher Mg and Cr levels in Rv in FWD. In the case of SWD, serum levels of Sr are confirmed as the best parameter for diagnosis, although other trace elements may also be useful, such as the serum concentrations of Mg and Cl. In the case of FWD, the joint determination of Sr and other biochemical markers, especially Fe, may increase correct diagnosis.

Evaluation of food consumption and dietary patterns in Spain by the Food Consumption Survey: updated information.

BACKGROUND/OBJECTIVES: The Food Consumption Survey (FCS), conducted for over 20 years by the Spanish Ministry of Agriculture, Fisheries and Food (MARM), is the most reliable source of data to evaluate the food consumption and dietary patterns of Spain. The aim of this study was to assess population food availability per capita per day, which allows the calculation of energy and nutrient intake and comparison with the Recommended Nutrient Intakes for the Spanish population. In addition, different markers of the quality of the diet have been evaluated. SUBJECTS/METHODS: The sample consisted of consumption and distribution data, obtained from the nationwide representative FCS for the period 2000-2006. A two-stage sampling method was applied, where in the first stage the units to be sampled were towns or local entities, and in the second stage households that were going to be part of the final sample from those entities were selected. Units consisted of towns or local entities in the national territory. The sample size was 619 selected entities. Units in the second stage were households from the selected towns (8200 homes). The data allowed the calculation of energy and nutrient intakes, using food composition tables. The quality of the diet was also evaluated: the adequacy of the diet in meeting the recommended intakes for energy and nutrients; energy profile; dietary fat quality; dietary protein quality; nutrient density; and Mediterranean diet adequacy indices. The present data were compared with previous data obtained by our research group in 1964, 1981 and 1991. RESULTS: Using the most recent data, average intake comprised milk and derivatives (379 g/person/day), fruit (310 g/person/day), vegetables and greens (302 g/person/day), cereals and derivatives (214 g/person/day), meat and meat products (179 g/day), fish (100 g/person/day), oil and fat (48 g/person/day), precooked food (34 g/person/day), eggs (32 g/person/day), and legumes and pulses (11.9 g/person/day). There was also a high consumption of non-alcoholic beverages (433 g/person/day) and alcoholic beverages (247 g/person/day). In consequence, meat and meat product consumption was higher than the recommendations, whereas for cereals and their derivatives, vegetables and greens, fruit, and legumes and pulses, consumption was below recommendations for the Spanish population. Some staple and traditional Mediterranean foods (bread, potatoes and olive oil) showed a dramatic decline when compared with data from Household Budget Surveys in 1964 data. Energy intake declined by about 300 kcal/person/day, when compared with the 1964 mean consumption. Insufficient nutrient intakes were found in the young adult population for zinc and folic acid in both sexes, and for iron in women, when compared with dietary reference values. CONCLUSIONS: Food consumption patterns in Spain and energy and nutrient intakes have changed markedly in the last 40 years, differing at present from the traditional and healthy Mediterranean diet.

Excessive fructose intake induces the features of metabolic syndrome in healthy adult men: role of uric acid in the hypertensive response.

BACKGROUND: Excessive fructose intake causes metabolic syndrome in animals and can be partially prevented by lowering the uric acid level. We tested the hypothesis that fructose might induce features of metabolic syndrome in adult men and whether this is protected by allopurinol. METHODS: A randomized, controlled trial of 74 adult men who were administered 200 g fructose daily for 2 weeks with or without allopurinol. Primary measures included changes in ambulatory blood pressure (BP), fasting lipids, glucose and insulin, homeostatic model assessment (HOMA) index, body mass index and criteria for metabolic syndrome. RESULTS: The ingestion of fructose resulted in an increase in ambulatory BP (7+/-2 and 5+/-2 mm Hg for systolic (SBP) and diastolic BP (DBP), P<0.004 and P<0.007, respectively). Mean fasting triglycerides increased by 0.62+/-0.23 mmol l(-1) (55+/-20 mg per 100 ml), whereas high-density lipoprotein cholesterol decreased by 0.06+/-0.02 mmol l(-1) (2.5+/-0.7 mg per 100 ml), P<0.002 and P<0.001, respectively. Fasting insulin and HOMA indices increased significantly, whereas plasma glucose level did not change. All liver function tests showed an increase in values. The metabolic syndrome increased by 25-33% depending on the criteria. Allopurinol lowered the serum uric acid level (P<0.0001) and prevented the increase in 24-h ambulatory DBP and daytime SBP and DBP. Allopurinol treatment did not reduce HOMA or fasting plasma triglyceride levels, but lowered low-density lipoprotein cholesterol relative to control (P<0.02) and also prevented the increase in newly diagnosed metabolic syndrome (0-2%, P=0.009). CONCLUSIONS: High doses of fructose raise the BP and cause the features of metabolic syndrome. Lowering the uric acid level prevents the increase in mean arterial blood pressure. Excessive intake of fructose may have a role in the current epidemics of obesity and diabetes.

Coberturas y factores asociados a la vacunación antigripal entre los niños españoles que padecen asma / Coverage and factors associated with anti-influenza vaccination among spanish children suffering asthma

Objetivos: Determinar la cobertura vacunal y los factores asociados con la vacunación antigripal en los niños españoles que padecen asma. Métodos: Se han analizado los registros individuos menores de 18 años incluidos en la Encuesta Nacional de Salud (ENS) de España del año 2003. Se han seleccionado para este trabajo los sujetos que declaran padecer asma. Como variable dependiente se ha utilizado la respuesta (“si”o “no”) a la pregunta, “Querríamos saber si su hijo se ha vacunadode la gripe en la última campaña”. Se analiza la influenza de variables sociodemográficas, estilos de vida, comorbilidad, percepción de la salud y uso de servicios sanitarios sobre la vacunación antigripal y se describe quién le indicó la vacunación al niño. Resultados: Se han analizado los registros de 6.869 individuos de ellos 313 (4,6%) declaraban padecer asma y el 19,9% señalaban haberse vacunado frente a la gripe en la ultima campaña. Entre los niños no asmáticos la cobertura era del 4,6%.(p<0,05)El único factor asociado significativamente con la vacunación antigripal en los niños asma fue el nivel de ingresos en el hogar, demostrándose que los que viven en hogares con mayor nivel de ingresos tenían mayor probabilidad de estar vacunados. La recomendación por parte el medico es el motivo señalado mayoritariamente para haber sido vacunado de la gripe. Conclusiones: Concluimos que las coberturas vacunales antigripales entre los niños asmáticos españoles son injustificablemente bajas y se hace imprescindible que se tomen medidas urgentes para mejorarlas

Objectives: To ascertain anti-influenza vaccination coverage and factors associated with anti-influenza vaccination among Spanish children suffering asthma. Methods: We analyzed data of subjects age under 18 years included in the Spanish National Health Survey (ENS) for 2003. We selected those children whose parents declared to be asthmatic. As a dependent variable, we used the reply (“yes” or “no”) to the question: Was your child vaccinated against influenza during the last campaign?”. We analyzed the influence variables regarding sociodemographic characteristics, life styles, comorbility, self rated health and use of health services on vaccination. The reason for vaccination is described. Results: Finally 6.869 children were analyzed, 313 (4.6%) were classified as asthmatics and the vaccination coverage for the last campaign was 19.9%. Among those without asthma coverage reached only 4.6% (p<0.05). The only factor significantly associated with anti-influenza vaccination in children with asthma was household income: those from homes with a higher level of income were more likely to be vaccinated. The main reason for vaccination in the infant population was “Recommendationby the physician”. Conclusions: Anti-influenza vaccination coverage in the Spanish asthmatic infant population is unjustifiably low. Strategies must be implemented urgently to improve such low coverages
