Efecto complementario de abonos verdes en precocidad, calidad y rendimiento en un cultivo de melón orgánico (Cucumis melo L. var. cantalupensis Naud) cv Araucano.

68 p.La investigación se llevó a cabo en la estación experimental Panguilemo de la Universidad de Talca, en el sector destinado para producción orgánica, entre el periodo del 26 de Abril de 2010 hasta el 17 de Marzo de 2011. En el ensayo se evaluó el uso de abonos verdes, como fertilización complementaria, en la producción orgánica de melón (Cucumis melo L. var. cantalupensis Naud) cv. Araucano. Para realizar el ensayo se utilizó un diseño de bloques completamente al azar, con 4 repeticiones por tratamiento. Los tratamientos son avenavicia, centeno-vicia, ballica-trébol blanco, ballica, ballica-vicia y centeno. El cultivo de melón se estableció en el lugar donde se incorporaron los abonos verdes, y se llevó a cabo mediante un manejo de cultivo forzado, donde se utilizó un mulch de color naranjo y una malla textil agrícola. El objetivo del estudio fue evaluar los abonos verdes sobre los rendimientos, la precocidad y la calidad del melón en producción orgánica. En los abonos verdes se evaluó la cantidad de materia seca y posterior a esto el análisis de nutrientes de cada uno de ellos. En el cultivo de melón se evaluaron los rendimientos (comercial, descarte y total), frutos por planta, sólidos solubles (°Brix), presión de pulpa (lb/plg2), diámetros distal y ecuatorial, y materia seca de la planta. Los resultados fueron sometidos a un análisis de varianza (ANDEVA) y donde se encontró diferencias significativas se realizó separación de medias con el test de Tukey (5%). En la cantidad de materia seca y aporte de nutrientes de los abonos verdes, el tratamiento centeno-vicia es el que obtuvo el mejor rendimiento con 3492,5 (kg/ha) y 77,23 kg N/ha respectivamente. En el caso del melón los mayores rendimientos totales, tanto en cantidad como en toneladas, fueron presentados en el tratamiento centeno-vicia con 38636,9 fr/ha y 62 t/ha respectivamente. El tratamiento que presentó mayor número de frutos por planta, tanto frutos comerciales como totales, fue centeno-vicia con 1,26 y 1,46 respectivamente. Los sólidos solubles y la presión de pulpa no presentaron diferencias entre los distintos tratamientos, igualmente el diámetro ecuatorial y distal de los frutos. El número de guías terciarias de la planta presentó diferencias significativas. Finalmente la mezcla centeno-vicia contribuyó con la mayor cantidad de materia seca de la planta de melón, con 3312,8 kg/ha./ABSTRACT: The research was carried out in the Panguilemo experimental station in the University of Talca, in the place destined to organic production, between 26 April 2010 and 17 March 2011. In the experiment were evaluated the use of green manure as complementary fertilization in the production of organic melon (Cucumis melo L. var. cantalupensis Naud) cv. Araucano. To make the test was used a design of completely randomized block, with 4 repetitions for every treatment. The treatments are oats-vicia, rye-vicia, ryegrass-white clover, ryegrass, ryegrassviciaand rye. The cultivation of melon was established in the place where green manures were incorporated and it was carried out through a forced crop management, where an orange mulch and an agricultural textile mesh were used. The objective of the study was evaluated the green manures about to the yields, the precocity and the melon quality in organic production. In the green manures was evaluated the amount of dry matter and subsequent to this, the analysis of nutrients of each of them. In the melon cultivation were evaluated the yields (commercial, discard and total), fruits per plants, soluble solids (°Brix), pulp pressure (lb/plg2), distal and equatorial diameters and dry matter of the plant. The results were subjected to analysis of variance (ANOVA), and where significant differences were found, an average separation was done applying the Tukey (5%) test. In the amount of dry matter and nutrients contribution of green manures, the rye-vicia treatment got the best yield with 3492, 5 (kg/ha) and 77, 23 kg N/ha, respectively. In the melon case the highest total yields, as in quantity as in tons, were presented in rye-vicia treatment with 38636, 9 fr/ha and 62 t/ha respectively. The treatment that presented the greatest number of fruits per plant, as commercial as total fruit, was rye + vicia, with 1, 26 and 1, 46 respectively. The soluble solids and pulp pressure did not present differences among the diverse treatments, equally the equatorial and distal diameter of the fruits. The number of tertiary guides of the plant presented significant differences. Finally, the mix of rye+ vicia contributed with the major quantity of dry matter in the melon plant with 3312, 8 kg/ha

HCV-coinfection is related to an increased HIV-1 reservoir size in cART-treated HIV patients: a cross-sectional study

In HIV-1/HCV-coinfected patients, chronic HCV infection leads to an increased T-lymphocyte immune activation compared to HIV-monoinfected patients, thereby likely contributing to increase HIV-1 reservoir that is the major barrier for its eradication. Our objective was to evaluate the influence of HCV coinfection in HIV-1 viral reservoir size in resting (r) CD4+ T-cells (CD25-CD69-HLADR-). Multicenter cross-sectional study of 97 cART-treated HIV-1 patients, including 36 patients with HIV and HCV-chronic co-infection without anti-HCV treatment, 32 HIV patients with HCV spontaneous clearance and 29 HIV-monoinfected patients. rCD4+ T-cells were isolated and total DNA was extracted. HIV viral reservoir was measured by Alu-LTR qPCR. Differences between groups were calculated with a generalized linear model. Overall, 63.9% were men, median age of 41 years and Caucasian. Median CD4+ and CD8+ T-lymphocytes were 725 and 858 cells/mm 3 , respectively. CD4+ T nadir cells was 305 cells/mm 3 . Proviral HIV-1 DNA size was significantly increased in chronic HIV/HCV-coinfected compared to HIV-monoinfected patients (206.21 ± 47.38 vs. 87.34 ± 22.46, respectively; P = 0.009), as well as in spontaneously clarified HCV co-infected patients when compared to HIV-monoinfected individuals (136.20 ± 33.20; P = 0.009). HIV-1/HCV co-infected patients showed a larger HIV-1 reservoir size in comparison to HIV-monoinfected individuals. This increase could lead to a greater complexity in the elimination of HIV-1 reservoir in HIV-1/HCV-coinfected individuals, which should be considered in the current strategies for the elimination of HIV-1 reservoir.Financial support was provided by the Instituto de Salud Carlos III to VB (PI15CIII/00031), by the Spanish Ministry of Economy and Competitiveness to MC (SAF2016–78480-R) and The SPANISH AIDS Research Network RD16CIII/0002/0001, RD16CIII/0002/0002 and RD16/0025/0013 - ISCIII – FEDER.

Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)

This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Albiglutide and cardiovascular outcomes in patients with type 2 diabetes and cardiovascular disease (Harmony Outcomes): a double-blind, randomised placebo-controlled trial

Background: Glucagon-like peptide 1 receptor agonists differ in chemical structure, duration of action, and in their effects on clinical outcomes. The cardiovascular effects of once-weekly albiglutide in type 2 diabetes are unknown. We aimed to determine the safety and efficacy of albiglutide in preventing cardiovascular death, myocardial infarction, or stroke. Methods: We did a double-blind, randomised, placebo-controlled trial in 610 sites across 28 countries. We randomly assigned patients aged 40 years and older with type 2 diabetes and cardiovascular disease (at a 1:1 ratio) to groups that either received a subcutaneous injection of albiglutide (30–50 mg, based on glycaemic response and tolerability) or of a matched volume of placebo once a week, in addition to their standard care. Investigators used an interactive voice or web response system to obtain treatment assignment, and patients and all study investigators were masked to their treatment allocation. We hypothesised that albiglutide would be non-inferior to placebo for the primary outcome of the first occurrence of cardiovascular death, myocardial infarction, or stroke, which was assessed in the intention-to-treat population. If non-inferiority was confirmed by an upper limit of the 95% CI for a hazard ratio of less than 1·30, closed testing for superiority was prespecified. This study is registered with ClinicalTrials.gov, number NCT02465515. Findings: Patients were screened between July 1, 2015, and Nov 24, 2016. 10 793 patients were screened and 9463 participants were enrolled and randomly assigned to groups: 4731 patients were assigned to receive albiglutide and 4732 patients to receive placebo. On Nov 8, 2017, it was determined that 611 primary endpoints and a median follow-up of at least 1·5 years had accrued, and participants returned for a final visit and discontinuation from study treatment; the last patient visit was on March 12, 2018. These 9463 patients, the intention-to-treat population, were evaluated for a median duration of 1·6 years and were assessed for the primary outcome. The primary composite outcome occurred in 338 (7%) of 4731 patients at an incidence rate of 4·6 events per 100 person-years in the albiglutide group and in 428 (9%) of 4732 patients at an incidence rate of 5·9 events per 100 person-years in the placebo group (hazard ratio 0·78, 95% CI 0·68–0·90), which indicated that albiglutide was superior to placebo (p&lt;0·0001 for non-inferiority; p=0·0006 for superiority). The incidence of acute pancreatitis (ten patients in the albiglutide group and seven patients in the placebo group), pancreatic cancer (six patients in the albiglutide group and five patients in the placebo group), medullary thyroid carcinoma (zero patients in both groups), and other serious adverse events did not differ between the two groups. There were three (&lt;1%) deaths in the placebo group that were assessed by investigators, who were masked to study drug assignment, to be treatment-related and two (&lt;1%) deaths in the albiglutide group. Interpretation: In patients with type 2 diabetes and cardiovascular disease, albiglutide was superior to placebo with respect to major adverse cardiovascular events. Evidence-based glucagon-like peptide 1 receptor agonists should therefore be considered as part of a comprehensive strategy to reduce the risk of cardiovascular events in patients with type 2 diabetes.

Changes in the Mechanical Properties of the Horizontal Force-Velocity Profile during a Repeated Sprint Test in Professional Soccer Players

The objective was to analyze the changes in the horizontal force-velocity profile (HFVP) during the execution of repeated sprinting. Methods: Seventeen first-division Chilean soccer players completed a repeated sprint protocol consisting of eight sprints of 30 m with 25-s pauses between repetitions. The behavior of HFVP variables in each attempt was recorded from video recordings and analysis in the MySprint&reg; application. Results: Differences (p &lt; 0.05) were found between sprints in the following: time (T), starting from sprint 5 (F = 35.6; &eta;2p = 0.69); theoretical maximum speed (V0), starting from sprint 4 (F = 29.3; &eta;2p = 0.51); maximum power (PM), starting from sprint 5 (F = 17; &eta;2p = 0.52); rate of decrease in force index produced at each step (DRF), starting from sprint 1 (F = 3.20; &eta;2p = 0.17); and RF10, starting from sprint 1 (F = 15.5; &eta;2p = 0.49). In comparison, F0 and RFpeak did not present any differences (p &gt; 0.05). Conclusion: The HFVP variables more sensitive to the effects of fatigue induced by an RSA protocol are those associated with the production of force at high speeds, being V0, DRF, and Pmax, while those that contribute to the generation of force at the beginning of the sprint, F0 and RFpeak, do not present essential variations

Avances sobre el conocimiento de la geología y la bioestratigrafía del mioceno tardío–plioceno de la provincia de Mendoza

En las Huayquerías del Este, provincia de Mendoza, afloran las formaciones Huayquerías (Mioceno tardío) y la suprayacente Tunuyán (Plioceno), correspondientes a una secuencia sinsedimentaria. Se presentan 15 perfiles estratigráficos nuevos de detalle sobre la base de los atributos litofaciales, su asociación de facies y la caracterización de sus cuerpos sedimentarios, observándose la alternancia de tres niveles depositacionales (aluvial-distal, fluvial y eólico) en un ambiente árido. Se reportan fechados radiométricos de cinco niveles cineríticos para la Formación Huayquerías y uno para la Formación Tunuyán. Se identificaron taxonómicamente 1163 ejemplares (Colección de Paleovertebrados del IANIGLA), recuperados con estricto control estratigráfico, representando 56 taxones en la Formación Huayquerías y 55 en la Formación Tunuyán, distribuidos en 22 y 21 familias, respectivamente (compartiendo 16). Los valores del Coeficiente Corregido de Forbes (0,92 y 0,866 para familia y género, respectivamente) entre ambas formaciones muestran una alta similitud en su composición taxonómica. Sin embargo, los resultados de la curva de acumulación de familias y géneros (rarefacción) sugieren falencias de registro, mayores a nivel de género en la Formación Huayquerías. Comparativamente, a nivel local, la Formación Huayquerías presenta 20 últimos registros, siete a nivel de género: Cyonasua, Huayqueriana, Typotheriopsis, Pronothrotherium, Pseudoeuryurus, Reigechimys y Ullumys (Mammalia), mientras que la Formación Tunuyán presenta 19 primeros registros, seis a nivel de género: Lepidobatrachus (Amphibia), “Cercomys”, Cardiatherium, Eucelophorus, Thylamys y Paleuphractus (Mammalia). La procedencia estratigráfica precisa de los ejemplares de las dos asociaciones, relacionada con los horizontes datados, permitirá comparar con otras asociaciones fósiles de diversas faunas sudamericanas con cronoestratigrafía conocida.Fil: Romano Muñoz, Cristo Omar.
