Abstract
Complex oxides offer a wide range of functional properties, and recent advances in the fabrication of freestanding membranes of these oxides are adding new mechanical degrees of freedom to this already rich functional ecosystem. Here, photoactuation is demonstrated in freestanding thin film resonators of ferroelectric Barium Titanate (BaTiO3) and paraelectric Strontium Titanate (SrTiO3). The free-standing films, transferred onto perforated supports, act as nano-drums, oscillating at their natural resonance frequency when illuminated by a frequency-modulated laser. The light-induced deflections in the ferroelectric BaTiO3 membranes are two orders of magnitude larger than in the paraelectric SrTiO3 ones. Time-resolved X-ray micro-diffraction under illumination and temperature-dependent holographic interferometry provide combined evidence for the photostrictive strain in BaTiO3 originating from a partial screening of ferroelectric polarization by photo-excited carriers, which decreases the tetragonality of the unit cell. These findings showcase the potential of photostrictive freestanding ferroelectric films as wireless actuators operated by light.

Abstract
Seasonal windows of opportunity are intervals within a year that provide improved prospects for growth, survival, or reproduction. However, few studies have sufficient temporal resolution to examine how multiple factors combine to constrain the seasonal timing and extent of developmental opportunities. Here, we document seasonal changes in milkweed (Asclepias fascicularis)-monarch (Danaus plexippus) interactions with high resolution throughout the last three breeding seasons prior to a precipitous single-year decline in the western monarch population. Our results show early- and late-season windows of opportunity for monarch recruitment that were constrained by different combinations of factors. Early-season windows of opportunity were characterized by high egg densities and low survival on a select subset of host plants, consistent with the hypothesis that early-spring migrant female monarchs select earlier-emerging plants to balance a seasonal trade-off between increasing host plant quantity and decreasing host plant quality. Late-season windows of opportunity were coincident with the initiation of host plant senescence, and caterpillar success was negatively correlated with heatwave exposure, consistent with the hypothesis that late-season windows were constrained by plant defense traits and thermal stress. Throughout this study, climatic and microclimatic variations played a foundational role in the timing and success of monarch developmental windows by affecting bottom-up, top-down, and abiotic limitations. More exposed microclimates were associated with higher developmental success during cooler conditions, and more shaded microclimates were associated with higher developmental success during warmer conditions, suggesting that habitat heterogeneity could buffer the effects of climatic variation. Together, these findings show an important dimension of seasonal change in milkweed-monarch interactions and illustrate how different biotic and abiotic factors can limit the developmental success of monarchs across the breeding season. These results also suggest the potential for seasonal sequences of favorable or unfavorable conditions across the breeding range to strongly affect monarch population dynamics.

Abstract
BACKGROUND Controlled donation after circulatory death (cDCD) has expanded the donor pool for liver transplantation (LT). However, transfusion requirements and perioperative outcomes should be elucidated. The aim of this multicenter study was to assess red blood cell (RBC) transfusions, one-year graft and patient survival after LT after cDCD with normothermic regional perfusion (NRP) compared with donors after brain death (DBD). METHODS 591 LT carried out in ten centers during 2019 were reviewed. Thromboelastometry was used to manage coagulation and blood product transfusion in all centers. Normothermic regional perfusion was the standard technique for organ recovery. RESULTS 447 patients received DBD and 144 cDCD with NRP. Baseline MCF Extem was lower in the cDCD group There were no differences in the percentage of patients (63% vs. 61% p = 0.69), nor in the number of RBC units transfused (4.7 (0.2) vs 5.5 (0.4) in DBD vs cDCD, p = 0.11. Twenty-six patients (6%) died during admission for LT in the DBD group compared with 3 patients (2%) in the cDCD group (p = 0.15). To overcome the bias due to a worse coagulation profile in cDCD recipients, matched samples were compared. No differences in baseline laboratory data, or in intraoperative use of RBC or one-year outcome data were observed between DBD and cDCD recipients. CONCLUSIONS cDCD with NRP is not associated with increased RBC transfusion. No differences in graft and patient survival between cDCD and DBD were found. Donors after controlled circulatory death with NRP can increasingly be utilized with safety, improving the imbalance between organ donors and the ever-growing demand.

Abstract
BACKGROUND Cell-free DNA (cfDNA) analysis using peripheral blood represents an exciting, minimally invasive technology for cancer diagnosis and monitoring. The reliability of testing is dependent on the accuracy and sensitivity of specific molecular analyses to detect tumor-associated genomic variants and on the quantity and quality of cfDNA available for testing. Specific guidelines for standardization and design of appropriate quality programs focused specifically on cfDNA isolation are lacking, as are standardized quality control reagents. CONTENT This report describes and illustrates quality control and quality assurance processes, supported by generation of in-house quality control material, to ensure the reliability of the preanalytical phase of cfDNA analysis. SUMMARY We have developed a robust quality program to support high-volume automated cfDNA extraction from peripheral blood by implementing processes and procedures designed to monitor the adequacy of specimen collection, specimen stability, efficiency of cfDNA extraction, and cfDNA quality.

Abstract
Abstract
Introduction
Cardiovascular disease risk augments with advance of age. The mechanism of the increased cardiovascular disease risk by aging is related to attenuation of arterial function via endothelium-derived relaxing factor, such as nitric oxide (NO). Recently, apelin and adropin have identified as NO-upregulated hormones, whereas augmented secretion of asymmetric dimethylarginine (ADMA) have identified as NO-downregulated hormones. However, the effects of exercise training-induced changes in NO-regulated hormones on the reduction of arterial stiffness via NO productions remain unclear.
Purpose
This study aimed to determine the time-dependent changes in NO-regulated hormones related to exercise-training effects of arterial stiffness via NO productions in healthy middle-aged and older adults.
Methods
Thirty-two Japanese healthy middle-aged and older subjects (67±1 years) were randomly divided into two groups: exercise intervention and sedentary controls. Subjects in the training group completed 8-week of aerobic exercise training (60–70% peak oxygen uptake [VO2peak] for 45 min, 3 days/week). We evaluated plasma nitrite/nitrate (NOx), apelin, and ADMA levels, serum apelin level and carotid-femoral pulse wave velocity (cfPWV) as an index of arterial stiffness, measured every 2 weeks for 8-week in the training group.
Results
cfPWV was gradually declined from baseline to 8-week and significantly decreased from baseline at weeks 6 (P<0.05) and 8 (P<0.01). Plasma NOx level was gradually elevated during exercise intervention and significantly increased from baseline at weeks 6 (P<0.05) and 8 (P<0.01). Interestingly, plasma apelin and serum adropin levels were gradually elevated during exercise intervention and significantly increased from baseline at weeks 4, 6 and 8 (each P<0.01). Additionally, plasma ADMA level was significantly decreased at 8-week intervention (P<0.01). Furthermore, the exercise training-induced increase in plasma NOx level was significantly correlated with the changes in circulating apelin (r=0.505, P<0.05), adropin (r=0.662, P<0.01), or ADMA (r=−0.483, P<0.05) levels before and after the 8-week. The exercise training-induced increase in plasma NOx level was significantly correlated with training-induced changes in circulating apelin (r=0.483, P<0.05) or adropin (r=0.556, P<0.05) before and after the 6-week.
Conclusions
These results suggest that the NO-upregulated hormones (apelin and adropin) were increased at the early stage of exercise training intervention and NO-downregulated hormone (ADMA) was decreased at the late stage of exercise training intervention, and these changes in NO-regulated hormones may be contributed to the reduction of arterial stiffness in the middle-aged and older adults.

Abstract
The C56R mutation associated with factor XI deficiency has been first evidenced in individuals from the French Basque Country. Genetic investigations revealed that this mutation occurred about 5400 years ago as a founder effect in this zone. Other cases were subsequently described in Southwestern Europe. Noticeably a cluster of cases was evidenced in Yecla, a small city from the province of Murcia, in Southeastern Spain. In correlation with historical sources our genetic data and surname analysis argue for associating this mutation with the migration of people from Western Pyrenees (and more probably from the Navarra province) toward Southeastern Spain during the Reconquista period.

Abstract
Abstract
Background
Sugar-sweetened beverage consumption is contributing to the obesity epidemic. On 28 March 2017, Catalonia enacted a law levying an excise tax on sugar-sweetened beverages for public health reasons. The purpose of this study is to assess the impact of the tax on the consumption of sugar-sweetened beverages in Catalonia (Spain).
Methods
Before-and-after study to assess changes in the prevalence of consumption of sugar-sweetened beverages among 1929 persons aged 12 to 40 years residing in low-income neighbourhoods of Barcelona (intervention) and Madrid (control). Beverage consumption frequency was ascertained via a validated questionnaire administered during the month prior to the tax’s introduction (May 2017) and again at one year after it had come into force. The effect of the tax was obtained using Poisson regression models with robust variance.
Results
While the prevalence of regular consumers of taxed beverages fell by 41% in Barcelona as compared to Madrid, the prevalence of consumers of untaxed beverages remained stable. The main reason cited by more than two-thirds of those surveyed for reducing their consumption of sugar-sweetened beverages was the increase in price, followed by a heightened awareness of their health effects.
Conclusions
The introduction of the Catalonian excise tax on sugar-sweetened beverages was followed by a reduction in the prevalence of regular consumers of taxed beverages.
Key messages
This is the first study to show the efficacy of the Catalonian excise tax to reduce the prevalence of regular consumers of sugar sweetened beverages by residents of low-income neighbourhoods in Spain. Our results, along with the remaining scientific evidence on the subject, would justify the extension of the measure to the rest of Spain for public health reasons.

Abstract
Anatomy Academy is a simultaneous service-learning experience for preprofessional school undergraduate students and preclinical professional students acting as classroom paraprofessional teachers (Mentors), and engaged-learning experience for fourth to sixth grade elementary school children (Students). Using didactic and kinesthetic active learning teaching strategies in small-group classroom environments, Mentors taught anatomy, physiology, and nutrition concepts to Students. In this study of the program's early years (2012-2014), overall objectives of improving Mentors' pedagogical confidence; and Students' science interest, science knowledge, and exercise self-efficacy were assessed. Mentors showed (89% response of 595 surveyed) improvement in content delivery (P < .001), student engagement (P < .001), classroom management (P < .001), and professionalism (P = .0001). Postprogram Mentor reflections were categorized into 7 major themes that demonstrated personal growth through the service-learning opportunity: (1) realization of an ability to make a difference in the world now; (2) acknowledgment of the importance of listening in teaching; (3) recognition that lives can and will change with "a little love"; (4) insight into the effectiveness of guiding Students through material rather than lecturing; (5) awareness of the value of respect in the learning environment; (6) cognizance of the power of individualized attention to motivate Students; and (7) reflection of one's own personal growth through the open influence of Students. Students showed (88% response of 1259 surveyed) improvement in science knowledge (P = .014) and exercise self-efficacy (P = .038), but not science interest (P = .371). Thus, while Students are learning more science and becoming more aware of their health, we need to be more overt in our presence as scientists in the educational arena.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Background Fluid resuscitation is not only used to prevent acute kidney injury (AKI) but fluid management is also a cornerstone of treatment for patients with established AKI and renal failure. Ultrafiltration removes volume initially from the intravascular compartment inducing a relative degree of hypovolemia. Normal reflex mechanisms attempt to sustain blood pressure constant despite marked changes in blood volume and cardiac output. Thus, compensated shock with a normal blood pressure is a major cause of AKI or exacerbations of AKI during ultrafiltration. Methods We undertook a systematic review of the literature using MEDLINE, Google Scholar and PubMed searches. We determined a list of key questions and convened a 2-day consensus conference to develop summary statements via a series of alternating breakout and plenary sessions. In these sessions, we identified supporting evidence and generated clinical practice recommendations and/or directions for future research. Results We defined three aspects of fluid monitoring: i) normal and pathophysiological cardiovascular mechanisms; ii) measures of volume responsiveness and impending cardiovascular collapse during volume removal, and; iii) measured indices of each using non-invasive and minimally invasive continuous and intermittent monitoring techniques. The evidence documents that AKI can occur in the setting of normotensive hypovolemia and that under-resuscitation represents a major cause of both AKI and mortality ion critically ill patients. Traditional measures of intravascular volume and ventricular filling do not predict volume responsiveness whereas dynamic functional hemodynamic markers, such as pulse pressure or stroke volume variation during positive pressure breathing or mean flow changes with passive leg raising are highly predictive of volume responsiveness. Numerous commercially-available devices exist that can acquire these signals. Conclusions Prospective clinical trials using functional hemodynamic markers in the diagnosis and management of AKI and volume status during ultrafiltration need to be performed. More traditional measure of preload be abandoned as marked of volume responsiveness though still useful to assess overall volume status.

Abstract
INTRODUCTION Factor XI (FXI) deficiency is a rare disorder with molecular heterogeneity in Caucasians but relatively frequent and molecularly homogeneous in certain populations. AIM To characterize FXI deficiency in a Spanish town of 60 000 inhabitants. METHODS A total of 324 764 APTT tests were screened during 20 years. FXI was evaluated by FXI:C and by Western blot. Genetic analysis of F11 was performed by sequencing, multiplex ligation-dependent probe amplification and genotyping. RESULTS Our study identified 46 unrelated cases and 170 relatives with FXI deficiency carrying 12 different genetic defects. p.Cys56Arg, described as founder mutation in the French-Basque population, was identified in 109 subjects from 24 unrelated families. This mutation was also identified in 2% of the general population. p.Cys416Tyr, c.1693G>A and p.Pro538Leu were identified in 7, 6 and 2 unrelated families, respectively. NGS analysis of the whole F11 gene revealed a common haplotype for each of the four recurrent mutations, suggesting a founder effect. The analysis of plasma FXI of four p.Pro538Leu homozygous carriers revealed that this variant was not activated by FXIIa. We identified four mutations previously described in other Caucasian subjects with FXI deficiency (p.Lys536Asn; p.Thr322Ile, p.Arg268Cys and c.325G>A) and four new gene defects: p.(Cys599Tyr) potentially causing a functional deficiency, p.(Ile426Thr), p.(Ile592Thr) and the first worldwide duplication of 1653 bp involving exons 8 and 9. Bleeding was rare and mild. CONCLUSIONS Our population-cohort study supplies new evidences that FXI deficiency in Caucasians is more common than previously thought and confirmed the wide underlying genetic heterogeneity, caused by both recurrent and sporadic mutations.

Abstract
Essentials Vitamin K-dependent coagulant factor deficiency (VKCFD) is a rare autosomal recessive disorder. We describe a case of inherited VKCFD due to uniparental disomy. The homozygous mutation caused the absence of GGCX isoform 1 and overexpression of Δ2GGCX. Hepatic and non-hepatic vitamin K-dependent proteins must be assayed to monitor VKCFD treatment. SUMMARY Background Inherited deficiency of all vitamin K-dependent coagulant factors (VKCFD) is a rare autosomal recessive disorder caused by mutations in the γ-glutamyl carboxylase gene (GGCX) or the vitamin K epoxide reductase gene (VKORC1), with great heterogeneity in terms of both clinical presentation and response to treatment. Objective To characterize the molecular basis of VKCFD in a Spanish family. Methods and Results Sequencing of candidate genes, comparative genomic hybridization and massive sequencing identified a new mechanism causing VKCFD in the proband. Uniparental disomy (UPD) of chromosome 2 caused homozygosity of a mutation (c.44-1G>A) resulting in aberrant GGCX splicing. This change contributed to absent expression of the mRNA coding for the full-length protein, and to four-fold overexpression of the smaller mRNA isoform lacking exon 2 (Δ2GGCX). Δ2GGCX might be responsible for two unexpected clinical observations in the patient: (i) increased plasma osteocalcin levels following vitamin K1 supplementation; and (ii) a mild non-bleeding phenotype. Conclusions Our study identifies a new autosomal disease, VKCFD1, caused by UPD. These data suggest that the Δ2GGCX isoform may retain enzymatic activity, and strongly encourage the evaluation of both hepatic and non-hepatic vitamin K-dependent proteins to assess differing responses to vitamin K supplementation in VKCFD patients.

Abstract
IMPORTANCE Understanding molecular mechanisms of response and resistance to anticancer therapies requires prospective patient follow-up and clinical and functional validation of both common and low-frequency mutations. We describe a whole-exome sequencing (WES) precision medicine trial focused on patients with advanced cancer. OBJECTIVE To understand how WES data affect therapeutic decision making in patients with advanced cancer and to identify novel biomarkers of response. DESIGN, SETTING, AND PATIENTS Patients with metastatic and treatment-resistant cancer were prospectively enrolled at a single academic center for paired metastatic tumor and normal tissue WES during a 19-month period (February 2013 through September 2014). A comprehensive computational pipeline was used to detect point mutations, indels, and copy number alterations. Mutations were categorized as category 1, 2, or 3 on the basis of actionability; clinical reports were generated and discussed in precision tumor board. Patients were observed for 7 to 25 months for correlation of molecular information with clinical response. MAIN OUTCOMES AND MEASURES Feasibility, use of WES for decision making, and identification of novel biomarkers. RESULTS A total of 154 tumor-normal pairs from 97 patients with a range of metastatic cancers were sequenced, with a mean coverage of 95X and 16 somatic alterations detected per patient. In total, 16 mutations were category 1 (targeted therapy available), 98 were category 2 (biologically relevant), and 1474 were category 3 (unknown significance). Overall, WES provided informative results in 91 cases (94%), including alterations for which there is an approved drug, there are therapies in clinical or preclinical development, or they are considered drivers and potentially actionable (category 1-2); however, treatment was guided in only 5 patients (5%) on the basis of these recommendations because of access to clinical trials and/or off-label use of drugs. Among unexpected findings, a patient with prostate cancer with exceptional response to treatment was identified who harbored a somatic hemizygous deletion of the DNA repair gene FANCA and putative partial loss of function of the second allele through germline missense variant. Follow-up experiments established that loss of FANCA function was associated with platinum hypersensitivity both in vitro and in patient-derived xenografts, thus providing biologic rationale and functional evidence for his extreme clinical response. CONCLUSIONS AND RELEVANCE The majority of advanced, treatment-resistant tumors across tumor types harbor biologically informative alterations. The establishment of a clinical trial for WES of metastatic tumors with prospective follow-up of patients can help identify candidate predictive biomarkers of response.

Abstract
The Affordable Care Act (ACA) has already resulted in expanded eligibility for Medicaid in 27 states, including California, as of 2014. One major concern about the Medicaid expansion is that a high level of need among the newly eligible may lead to runaway costs, which could overwhelm state budgets when federal subsidies no longer cover 100 percent of the expansion population's costs in 2017. Although cost increases as a result of the newly eligible are likely, an even more important question is whether these increases will be temporary or permanent. Evidence from California's Low Income Health Program (LIHP) suggests that cost and utilization increases among newly eligible Medicaid beneficiaries will be mostly temporary. This policy brief presents data showing a significant decline in the use of hospital inpatient care and in emergency room visits after one year of enrollment in LIHP, and a stable, not increasing, rate of outpatient service use. Because LIHP provided health care coverage from 2011 to 2013 in advance of the full Medicaid expansion, our findings suggest that early and significant investments in infrastructure and in improving the process of care delivery can effectively address the pent-up demand for health care services of previously uninsured populations.

Abstract
We examined the contractile responsiveness of rat thoracic aortas under pressure
overload after long-term suprarenal abdominal aortic coarctation (lt-Srac).
Endothelium-dependent angiotensin II (ANG II) type 2 receptor
(AT2R)-mediated depression of contractions to ANG II has been reported in
short-term (1 week) pressure-overloaded rat aortas. Contractility was evaluated in
the aortic rings of rats subjected to lt-Srac or sham surgery (Sham) for 8 weeks. ANG
I and II levels and AT2R protein expression in the aortas of lt-Srac and
Sham rats were also evaluated. lt-Srac attenuated the contractions of ANG II and
phenylephrine in the aortas in an endothelium-independent manner. However, lt-Srac
did not influence the transient contractions induced in endothelium-denuded aortic
rings by ANG II, phenylephrine, or caffeine in Ca2+-free medium or the
subsequent tonic constrictions induced by the addition of Ca2+ in the
absence of agonists. Thus, the contractions induced by Ca2+ release from
intracellular stores and Ca2+ influx through stored-operated channels were
not inhibited in the aortas of lt-Srac rats. Potassium-elicited contractions in
endothelium-denuded aortic rings of lt-Srac rats remained unaltered compared with
control tissues. Consequently, the contractile depression observed in aortic tissues
of lt-Srac rats cannot be explained by direct inhibition of voltage-operated
Ca2+ channels. Interestingly,
12-O-tetradecanoylphorbol-13-acetate-induced contractions in
endothelium-denuded aortic rings of lt-Srac rats were depressed in the presence but
not in the absence of extracellular Ca2+. Neither levels of angiotensins
nor of AT2R were modified in the aortas after lt-Srac. The results suggest
that, in rat thoracic aortas, lt-Srac selectively inhibited protein kinase C-mediated
activation of contraction that is dependent on extracellular Ca2+
entry.

Abstract
Adenoid cystic carcinomas (ACCs) from various anatomical sites harbor a translocation t(6;9)(q22-23;p23-24), resulting in MYB-NFIB gene fusion. This gene fusion is not well studied in mammary ACCs, and there are no studies examining this abnormality in solid variant of ACC with basaloid features (SBACC), a high-grade variant thought to behave more aggressively than ACCs with conventional histologic growth. Our aim was to investigate the frequency of MYB-NFIB gene fusion in mammary ACCs with a focus paid to SBACC. MYB rearrangement and MYB-NFIB fusion were assessed by fluorescence in situ hybridization and reverse-transcription polymerase chain reaction, respectively. Histologic features and the presence of MYB rearrangement were correlated with clinical outcome. MYB rearrangement was present in 7 (22.6%) of 31 mammary ACCs (5/15 [33.3%] ACCs with conventional growth; 2/16 [12.5%] SBACCs). One patient with conventional ACC developed distant metastasis, and no patients had axillary lymph node involvement by ACC (mean follow-up, 34 months; range, 12-84 months). Two patients with SBACC had axillary lymph node involvement at initial surgery, and 2 additional patients experienced disease recurrence (1 local, 1 distant; mean follow-up, 50 months; range, 9-192 months). MYB-NFIB fusion status did not correlate with clinical outcome in studied patients. We confirm that MYB-NFIB gene fusion is observed in mammary ACCs and that a subset lacks this abnormality. This study is the first to confirm the presence of MYB rearrangement in SBACC. Additional validation with long-term follow-up is needed to determine the relationship, if any, between MYB-NFIB gene fusion and clinical outcome.

Abstract
El índice masa corporal (IMC) es uno de los criterios mayormente utilizados para definir la obesidad en la población infantil. No obstante, el mismo determina el estado nutricional, mientras que el total de la grasa corporal demarca su composición corporal. Por lo tanto, el objetivo general del estudio fue determinar la relación entre el índice de masa corporal y el porcentaje de grasa corporal en 505 estudiantes (242 del sexo femenino y 263 masculino) de un Liceo Bolivariano del estado Barinas, con edades comprendidas entre 10 y 20 años. La investigación se enmarcó en el enfoque cuantitativo, con un tipo de investigación de campo, basado en un diseño no experimental, de nivel descriptivo-correlacional y de corte transversal. El análisis de datos se realizó a través del software estadístico SPSS versión 17.0. Los resultados presentan una correlación alta entre el IMC y el porcentaje de grasa (r: 0,75** para las chicas y r: 0,77** para los chicos; p<0,01). Asimismo, se presentaron correlaciones altas y significativas en los diferentes grupos de edad para ambos sexos. Para el masculino G1: r: 0,81, p<0,01; G2: r: 0,82**, p<0,01 y G3: r: 0,66**, p<0,01. En el caso del femenino la relación fue G1: r: 0,72**; G2: r: 0,83** y G3: r: 0,81**, p<0,01. Se concluye de esta manera que existe alta correlación positiva entre el IMC y el porcentaje de grasa corporal en la Institución Educativa mencionada, por lo tanto se considera la utilización del IMC como una herramienta aplicable para la estimación del estado nutricional.

Abstract
Sustained endoplasmic reticulum (ER) stress and thus activation of the unfolded protein response is now thought to be the foundation of various chronic disorders including whole-body insulin resistance and cardiovascular disease. The purpose of the present study was to test the hypothesis that ER stress impairs insulin-stimulated vasomotor reactivity. We report that experimental induction of ER stress in isolated aortic rings with tunicamycin (20 μg/mL), a well-established inducer of ER stress, resulted in insulin-stimulated vascular contraction (-78±21% at 1000 μIU/mL; -100±27% at 10,000 μIU/mL; all p<0.05) rather than relaxation (+23±7% at 1000 μIU/mL; +43±8% at 10,000 μIU/mL; all p<0.05). Importantly, we found that insulin-stimulated vascular contraction as a result of ER stress was largely eliminated in the presence of tezosentan (3 μM), a nonselective endothelin-1 (ET-1) receptor blocker (+1±14% at 1000 μIU/mL; +8±17% at 10,000 μIU/mL). Similarly, inhibition of ET-1 receptors fully restored the impairment of acetylcholine-mediated relaxation induced by ER stress (maximal relaxation: control = 94±2%, tunicamycin = 76±5%, tunicamycin + tezosentan = 90±3). Furthermore, we demonstrate that ER stress caused a ≈20-fold greater release of ET-1 from aortic endothelial cells under basal conditions as well as a ≈15-fold increase under insulin-stimulated conditions (p<0.05). This ER stress-mediated up-regulation in ET-1 release from endothelial cells was accompanied by a ≈3-fold increase in phosphorylation of p44/22 MAPK (p<0.05), a known pathway by which insulin signaling activates ET-1. Together, these findings support the hypothesis that vascular ER stress-mediated activation of ET-1 may be an underlying cause of impaired vasomotor responsiveness to insulin and endothelial dysfunction.

Abstract
BACKGROUND RNA quality is believed to decrease with ischaemia time, and therefore open radical prostatectomy has been advantageous in allowing the retrieval of the prostate immediately after its devascularization. In contrast, robotic-assisted laparoscopic radical prostatectomies (RALP) require the completion of several operative steps before the devascularized prostate can be extirpated, casting doubt on the validity of this technique as a source for obtaining prostatic tissue. We seek to establish the integrity of our biobanking process by measuring the RNA quality of specimens derived from robotic-assisted laparoscopic radical prostatectomy. METHODS We describe our biobanking process and report the RNA quality of prostate specimens using advanced electrophoretic techniques (RNA Integrity Numbers, RIN). Using multivariate regression analysis we consider the impact of various clinicopathological correlates on RNA integrity. RESULTS Our biobanking process has been used to acquire 1709 prostates, and allows us to retain approximately 40% of the prostate specimen, without compromising the histopathological evaluation of patients. We collected 186 samples from 142 biobanked prostates, and demonstrated a mean RIN of 7.25 (standard deviation 1.64) in 139 non-stromal samples, 73% of which had a RIN ≥ 7. Multivariate regression analysis revealed cell type--stromal/epithelial and benign/malignant--and prostate volume to be significant predictors of RIN, with unstandardized coefficients of 0.867(p = 0.001), 1.738(p < 0.001) and -0.690(p = 0.009) respectively. A mean warm ischaemia time of 120 min (standard deviation 30 min) was recorded, but multivariate regression analysis did not demonstrate a relationship with RIN within the timeframe of the RALP procedure. CONCLUSIONS We demonstrate the robustness of our protocol--representing the concerted efforts of dedicated urology and pathology departments--in generating RNA of sufficient concentration and quality, without compromising the histopathological evaluation and diagnosis of patients. The ischaemia time associated with our prostatectomy technique using a robotic platform does not negatively impact on biobanking for RNA studies.

Abstract
AIMS Postprandial lipaemia-induced endothelial dysfunction is felt to be mediated by increases in oxidative stress. In this review, we have examined the cross-sectional relationships found among these three variables. METHODS We found 20 studies conducted by 16 independent investigative teams through a Medline search from 1980 to 2008; studies were required to report correlations between at least two of the three variables of interest in studies of humans. This review is divided into (i) discussions on the biomarkers and other measures of postprandial lipaemia, oxidative stress and endothelial function; (ii) associations reported among the three variables; and (iii) other considerations including alternative intervention studies. RESULTS Triglycerides and free fatty acids are robust and well-standardised biomarkers of lipaemia. Measures of oxidative stress ranged from electron spin techniques to measures of lipid peroxidation and are limited by lack of standardisation. Brachial artery flow-mediated dilatation is the most commonly used measure of endothelial function. The associations between postprandial lipaemia and oxidative stress and between postprandial lipaemia and endothelial function are strong and consistent. However, the association between postprandial oxidative stress and endothelial function appears weak, at least using current approaches to measurement of oxidative stress. DISCUSSION AND CONCLUSIONS These observations are consistent with the proposed concept that oxidative stress mediates the adverse effects of postprandial lipaemia on endothelial function; they are limited by the difficulties in measuring oxidative stress. Efforts directed at optimising and standardising the measurement of oxidative stress will be of value in future works in this area.

Abstract
BACKGROUND Orthotopic liver transplantation (OLT) for patients with cirrhosis and concomitant hepatocellular carcinoma (HCC) in early stages is the treatment of choice, with an acceptable recurrence rate and excellent survival. AIM We sought to evaluate (1) the accuracy of preoperative imaging; (2) the impact of pre-OLT treatments on survival and recurrence; and (3) the influence of beyond Milan criteria selection on global outcomes. METHODS We studied a cohort of 65 patients with HCC among 300 consecutive OLTs over a single 12-year experience. We analyzed the overall outcomes of survival and recurrence, the accuracy of preoperative diagnosis and staging the influence of neoadjuvant treatment prior to OLT, and the effect on overall outcomes beyond the Milan criteria in our series. RESULTS The 65 transplants were performed for HCC, mostly in association with hepatitis C virus and alcoholic cirrhosis with HTP. At a mean follow-up of 40.32 months, the recurrence rate was 5.7% among the 61 HCC confirmed by histopathology. The overall survival was 30.07. Actuarial survivals at 1, 5, and 10 years were 82%, 77%, and 62%, respectively. Six retransplants occurred among the seven graft losses albeit with poor survival after the second graft. Most explants showed low pTNM stages with favorable microscopic features. Preoperative imaging tests failed to achieve an accurate diagnosis in 15.38% of the series. The role of alpha-fetoprotein (AFP) and hepatic biopsy was irrelevant. Unfavorable histopathologic factors predicted a greater recurrence rate, but had no influence on survival. Neither recurrence nor survival were modified by pre-OLT therapy. CONCLUSIONS In our series, AFP, hepatic biopsy, and pre-OLT treatment had limited roles. Radiological imaging techniques underestimated HCC staging and lead to a misdiagnosis to an expected degree. Despite these findings, this single institution experience with OLT for HCC showed excellent survivals with a low recurrence rate including cases of patients beyond the Milan criteria.

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) treated with dialysis have reduced levels of physical functioning. Little is known of the physical functioning in patients prior to initiation of renal replacement therapy (RRT). The purpose of the study was 2-fold: (i) to document physical functioning of patients with CKD not requiring RRT, using objective laboratory tests, physical performance measures and self-reported functioning; and (ii) to determine the correlations between these measures of physical functioning and renal function. METHODS Thirty-two patients with CKD (mean estimated glomerular filtration rate [eGFR] 29.9 +/- 17.0) were recruited for the study. Subjects completed symptom-limited treadmill test (peak oxygen uptake [VO2peak]), physical performance measures (gait speed, sit-to-stand and 6-minute walk) and the SF-36 Health Status Questionnaire (physical functioning scale [PF] and physical composite scale [PCS]). Descriptive and correlational analyses were performed on the data. RESULTS VO2peak (O2 17.8 +/- 6.7 ml/kg body weight per minute), physical performance measures and self-reported functioning were reduced compared with sedentary age-predicted norms. Significant correlations were found between VO2peak and all other physical functioning measures; however, only maximal gait speed and PCS correlated significantly with eGFR. CONCLUSIONS Patients with CKD have reduced physical functioning as measured using objective laboratory tests (VO2peak), physical performance measures and self-reported functioning. Given that low physical functioning predicts outcomes in dialysis patients, interventions to maintain or improve physical functioning are warranted prior to initiation of dialysis.

Abstract
OBJECTIVE Retrospective study on the relation between the use of blood products and survival rates in patients treated surgically for stage I non-small cell lung cancer (NSCLC). PATIENTS AND METHODS The study included 856 patients who underwent surgical resection from 1969 to 2000 for stage I NSCLC, classified histologically according to the current guidelines of the Spanish Society of Pulmonary and Thoracic Surgery (SEPAR). Patients who died in the postoperative period were excluded from the study. A series of clinicopathological variables were recorded, including the perioperative use or not of blood products. Descriptive, univariate, and multivariate statistical analyses were performed. Follow up concluded in December of 2003. RESULTS One hundred twenty-five patients (14.6%) underwent a perioperative transfusion. A significant association was found between the use of blood products and tumor size (P<.001), pneumectomy (P<.001), and cell type (P<.05). The respective 2, 5, and 10-year survival rates were 78%, 63%, and 54% for the nontransfusion group, and 73%, 59%, and 46% for the transfusion group. Both survival curves were compared and no significant differences were found (P=.23). Multivariate regression analysis included tumor size, patient age, and histologic cell type (squamous cell carcinoma or not); no relation between transfusion and survival was found. CONCLUSIONS In our series, we found no difference in survival rates for patients with stage I NSCLC after perioperative blood transfusion.

Abstract
OBJECTIVE To determine the incidence and causes of perioperative mortality following lung transplant for cystic fibrosis. PATIENTS AND METHODS We analyzed the cases of 57 patients. Fifty-five patients received double lung transplants, 1 received a heart-double lung transplant, and 1 received a combined double lung and liver transplant. Information related to the organ donor, recipient, lung graft, and early postoperative period was gathered. Perioperative mortality was defined as death resulting from anesthesia or surgery regardless of how many days had passed. The Kaplan-Meier method was used to analyze survival. A Cox logistic regression model was used to determine variables affecting mortality. RESULTS Survival was 83.7% at 1 year after transplantation, 77.3% at 2 years, and 66.9% at 5 years. Five (8.7%) patients died as a result of anesthesia or surgery. A ratio of PaO2 to inspired oxygen fraction (FiO2) less than 200 mm Hg in the early postoperative period was observed in 8 (14%) patients. Primary graft failure occurred in 4 patients, due to pneumonia in 2 and to biventricular dysfunction in 2. Three of those patients died. Two patients with PaO2/FiO2 greater than 200 mm Hg died after surgery, one from septic shock due to Pseudomonas cepacia and the other from massive cerebral infarction. PaO2/FiO2 upon admission to the recovery care unit was the only variable significantly associated with perioperative mortality in the logistic regression model (P=.0034). CONCLUSIONS The only factor significantly related to perioperative mortality in patients receiving transplants for cystic fibrosis was PaO2/FiO2 upon admission to the recovery unit.

Abstract
OBJECTIVE To determine the prognostic factors for the survival in a group of patients operated on for a non-small cell lung cancer classified as T2N1M0. PATIENTS AND METHODS Two hundred sixteen patients treated exclusively with surgery were studied. Kaplan-Meier survival and Cox multivariable regression analyses were used. RESULTS The overall survival rate was 39.8% at 5 years and 29.9% at 10 years. Sex, age, presence or absence of symptoms, type of resection, number, and location of affected lymph nodes had no effect on survival. Tumor size (P=.04) and histologic type (P=.03) did significantly affect prognosis. Both variables entered into the Cox multivariable regression model. CONCLUSIONS Patients operated on for non-small cell lung cancer classified as T2N1M0 have an overall probability of 5-year survival of approximately 40%. However, the prognosis for this group of patients is heterogeneous: in our study it was affected by the histologic type (45.5% for squamous cell and 25% for non-squamous cell cancers) and tumor size (53% for tumors with a diameter of <or=3 cm, 45% for tumors between 3.1 and 5 cm, and 29% for a tumor diameter >5 cm).

Abstract
OBJECTIVE To determine the causes of death in patients treated surgically for nonsmall cell lung cancer (NSCLC) in stage IA and to evaluate the impact on survival of not performing systematic lymph node dissection and of the number of nodes resected. PATIENTS AND METHODS The study sample consisted of 156 patients operated on for NSCLC and classified in stage IA according to TNM staging. Only palpable or visible lymph nodes were dissected. Kaplan-Meier survival curves were compared using a log-rank test. RESULTS At the end of the study, 85 (54.5%) patients had died, 67 (42.9%) were alive, and 4 (2.5%) were lost to follow up. Twenty-three (14.7%) died from a recurrence of NSCLC: 2 with local tumors (1.2%), 2 with mediastinal node involvement (1.2%), and 19 (12.1%) with distant metastasis. The cause of death was unrelated to NSCLC in 62 (39.7%) cases: 33 (21.1%) had a new tumor, 18 of which were bronchogenic, and 29 (18.5%) had nonmalignant disease. The 5-year survival rate was 81.4%. The rate was 88.9% among patients from whom no lymph nodes were excised and 79.9% among those with node excision, although the difference was not statistically significant (P=.4073). CONCLUSIONS Our experience suggests that neither the fact of not performing systematic lymph node dissection nor the number of nodes resected has an impact on survival. A substantial number of patients died of causes unrelated to the NSCLC for which they had been treated.
