Published: May 2017

Background:

Anatomical variation may represent a challenge in achieving a close fit between a prosthesis and a patient’s osseous geometry in total knee arthroplasty (TKA). The purposes of this study were to determine whether the shape of the distal part of the femur differs among ethnicities, whether these differences affect the fit of the femoral component of a standard prosthesis, and whether the additional availability of a femoral component with a reduced mediolateral dimension for the same anteroposterior dimension improves femoral component fit across ethnicities.

Methods:

Femoral dimensions were measured intraoperatively during 967 TKAs performed using the same type of prosthesis in patients of 5 different ethnicities. Aspect ratios were calculated to determine whether the shapes of the femora differed among ethnicities. The component fit (“perfect,” overhang, or underhang) when only standard prostheses were available was compared with the fit when both standard and narrow prostheses were available in all ethnic groups. This enabled us to determine whether the femoral component fit was improved by the additional availability of the narrow version.

Results:

Wide variations in shape were found among ethnicities as were variations among individuals of the same ethnicity. Differences in shape among ethnicities influenced the rate of overhang. However, overhang was more frequent at the trochlear than at the condylar level across all ethnicities. The availability of both the standard and the narrow femoral components improved the rate of a perfect fit in women in 3 of the 5 ethnic groups and reduced the overhang rate in women in all 5 of the ethnic groups. In contrast, only modest improvements in femoral component fit, which were not statistically significant, were seen in men.

Conclusions:

The shape of the distal part of the femur varies not only among ethnicities but also within ethnic groups, leading to a high prevalence of overhang when only standard prostheses are available. The additional availability of a femoral component with a reduced mediolateral dimension for the same anteroposterior size can reduce overhang and improve component fit across ethnicities.

Compared corn–soybean rotations with cover crops vs fallows under no‐till or till.

Corn–soybean rotations with cereal rye after corn decreased soil NO3–N by 42%.

Soil attributes and crop yields were generally unaffected by cover crops use.

Tillage increased soil organic matter and exchangeable K compared to no‐till.

Tillage reduced soybean yields by 245 kg/ha compared to no‐till.

Cover crops (CCs) have been heralded for their potential to improve soil properties, retain nutrients in the field, and subsequent crop yields, yet support for these claims within Illinois remains limited. Cover crops were used in corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations. We assessed five sets of CCs vs. fallow controls under no‐till (NT) and chisel till (Till) on soil attributes and crop yields, encompassing one complete rotation cycle. The experimental layout was a split split‐block where whole plot treatments (P, rotation phase; and Y, year) had a Latin square design and subplot treatments of tillage (NT vs. Till) were split into sub‐subplot treatments of CC rotations. We measured soil properties, crop yields, CC stand counts in late fall, and spring biomass samples, each year. Tillage increased the level of soil organic matter (SOM) and exchangeable potassium (K) within our systems yet significantly decreased the yield of soybean by 245 kg/ha. Compared to winter fallow, soil attributes under corn–soybean rotations that included CCs did not show any statistically significant change after one cycle of production except increased N scavenging with cereal rye growing after corn harvest. Inclusion of CCs in the corn–soybean rotation did not affect cash crop yields in either till or NT systems. Our results show that cereal rye is the CC with the best potential as an N scavenger in the corn–soybean rotation, but claims of crop yield increases in the short term are not supported.

Core Ideas

Spring maize mono‐cropping system is shown to be a water‐saving and high‐yield maize farming system.

Spring maize was traditionally planted in late April or early May but seldom obtained desirable yield.

Altering sowing date reduced frequency of high‐temperature stress of spring maize around silking and grain‐filling stage.

Altering sowing date improved assimilate availability of spring maize during the grain‐filling stage.

Late May turned out to be the better sowing date, rather than traditional sowing dates in late April or early May under current conditions.

The productivity of spring maize (Zea mays L.) in North China Plain (NCP) is primarily limited by high‐temperature stress (HTS) during the grain‐filling stage. To avoid HTS and promote productivity, variable sowing date (SD), treatments were established from 2013 to 2015 (early April, SD1; mid‐April, SD2; late April, SD3; early May, SD4; mid‐May, SD5; and late May, SD6). During the grain‐filling stage, the leaf area index (LAI) and dry matter accumulation (DMA) were greatest at the final SD (SD6) compared with all other treatments. Additionally, the daily mean air temperature (Tmean), daily maximum air temperature (Tmax), and cumulative stressful days (CSD) during this stage across 3 yr decreased at SD6 by 1.4 to 3.2°C, 1.0 to 2.7°C, and 5.7 to 14.7 d, respectively, compared with the values at SD1 to SD5. Planting at SD6 increased the final grain yield by an average of 5.4 to 19.3%. A linear regression analysis showed that the kernel number (KN) per plant increased by 4 with every 100 kg ha−1 DMA. Kernel number was negatively correlated with Tmax and CSD from 15 d pre‐silking to 15 d post‐silking. Compared to SD1 and SD4, ear leaf at 15 d post‐silking under the SD6 treatment had the highest net photosynthetic rate (Pn) and the lowest ABA concentration. In conclusion, to avoid HTS and achieve the greatest corn grain yields in NCP, spring sowing maize should be postponed until late May.

Published: May 2017

Core Ideas

Severe early‐season defoliation, such as hail injury, may cause abnormal growth and development of corn tassels.

If defoliation induced tassel deformation occurs within a large field, poor pollen production could greatly reduce yield.

Certain genetic backgrounds may be more likely to express tassel deformation in response to early‐season defoliation.

Published: May 2017

Microbial source tracking (MST) has been extensively used to detect the sources of fecal pollution in water. The inclusion of MST in water management strategies improves the ecological status of the ecosystem and human and animal health under interdisciplinary analysis in all aspects of health care for humans, animals, and the environment (One Health approach). In this study, the performance of MST markers targeting host‐specific Bacteroidales (HF183 and Rum‐2‐Bac) and Bifidobacterium species (HMBif and CWBif) were evaluated in raw sewage collected from human, ruminant, swine, and poultry sources in Tunisia, Cyprus, Ireland, and Spain. In addition, the ratio between somatic coliphages and bacteriophages infecting Bacteroides GA17 (SOMCPH/GA17PH) was measured in Tunisia and Spain. The obtained results showed variability of the bacterial markers between the four countries, suggesting that their usefulness could be affected by several conditions (dietary habits, agricultural practices, and climatic conditions) that differ between countries. The Rum‐2‐Bac marker stood out as a valid MST tool, particularly in Ireland, whereas CWBif was the best option in Tunisia, Spain, and Cyprus. The human‐specific HMBif marker showed good sensitivity and specificity in Tunisia, Spain, and Ireland, whereas HF183 showed a low specificity. However, HF183 was suggested as a good human marker in Ireland and Cyprus because of its higher concentration than HMBif. Regarding viral markers, the ratio of SOMCPH/GA17PH showed a clear discrimination between human and nonhuman samples. The combined use of molecular bacterial markers and the ratio of SOMCPH/GA17PH may improve the success of MST.

Core Ideas

• Differences among geographical areas have been observed for human source tracking markers

• Agricultural practices and/or climate conditions may affect the selection of ruminant MST markers.

• The MST markers described must be validated in each area before use for water management.

The sugarcane aphid (Melanaphis sacchari) has become a serious pest causing severe economic losses to sorghum [Sorghum bicolor (L.) Moench] grown in the southern United States. Since its original detection in four states in 2013, M. sacchari on sorghum has now, in 2016, spread to 19 states. The presence of one or multiple genotypes on sorghum in the United States has not yet been established. In this study, genome sequencing of M. sacchari was used to develop microsatellite markers. A total of 8,665,267 reads and 1.44 Gb of nucleotide sequences were generated, and 79.6% of the reads were from M. sacchari. Melanaphis sacchari DNA from 46 samples from 17 locations across seven states and one US territory was polymerase chain reaction (PCR) amplified using 38 newly created microsatellite markers, as well as 14 published microsatellite markers. Genotyping with the 52 microsatellite markers indicated that the samples of M. sacchari on sorghum were all one genotype, with the exception of a single sample collected from Sinton, TX, which had the predominant genotype as well as another genotype. Genotyping of the aphid samples with 12 microsatellite markers for Buchnera aphidicola, the obligate aphid symbiont, had nearly identical results. The invasive M. sacchari on sorghum appears to be spreading in the United States on sorghum as primarily one asexual clone.
Identification of Quantitative Trait Loci for Popping Traits and Kernel Characteristics in Sorghum Grain

Published: May 2017

Popped grain sorghum [Sorghum bicolor (L.) Moench] has developed a niche among specialty snack‐food consumers. In contrast with popcorn (Zea mays L.), sorghum has not benefitted from persistent selective breeding for popping efficiency and kernel expansion ratio. Although recent studies have already demonstrated that popping characteristics are heritable in sorghum, the discovery of quantitative trait loci (QTL) for these traits could help expedite and streamline the breeding process. To that end, the objective of this study was to identify regions of the sorghum genome associated with kernel popping traits. Using digital genotyping technology in conjunction with linkage mapping methodology, QTL were identified for kernel popping efficiency and kernel expansion ratio. Additionally, sets of QTL were identified for desirable traits including kernel weight, kernel diameter, kernel hardness, and kernel color. These results provide an initial assessment of regions of the sorghum genome that harbor trait loci controlling the popping quality of sorghum kernels and provide a basis for further detailed genetic studies of this relatively new use for food‐grade sorghum grain.

Core Ideas

Long‐term (30 yr) diversified crop rotations had a positive impact on soil C fractions.

Carbon fractions increased with increased rotation length.

Diversified rotations enhanced soil C sequestration and microbial biomass and activity.

Diversified crop rotations may enhance C fractions and soil quality by affecting the quality and quantity of crop residue returned to the soil compared with monocropping and fallow. We evaluated the effect of 30‐yr‐old diversified crop rotations on soil C fractions at 0‐ to 15‐, 15‐ to 30‐, and 0‐ to 30‐cm depths in the Loess Plateau of China. Crop rotations were continuous winter wheat (Triticum aestivum L.) (W); 3‐yr rotations of corn (Zea mays L.)–winter wheat–winter wheat–millet (Eleusine coracana L.) (CWWM), pea (Pisum sativum L.)–winter wheat–winter wheat–millet (PWWM), and sainfoin (Onobrychis viciifolia Scop.)–winter wheat–winter wheat–sainfoin (SWWS); 4‐yr rotation of pea–winter wheat–winter wheat–corn (PWWC); and 8‐yr rotation of alfalfa (Medicago sativa L.) (4 yr)–potato (Solanum tuberosum L.) (1 yr)–winter wheat (3 yr) (A4PoW3). A fallow (F) treatment was also included for comparison. Carbon fractions were soil organic C (SOC), particulate organic C (POC), potential C mineralization (PCM), and microbial biomass C (MBC). At all depths, SOC and POC were greater in A4PoW3 than F, W, and PWWC. The PCM and MBC were greater with SWWS than most other crops rotations. Soil C fractions increased linearly with increased belowground crop residue returned to the soil. Both SOC and POC increased linearly with increased rotation length. All C fractions were also correlated with mean annualized crop grain yield. Diversified crop rotations with increased belowground residue production enhanced soil C sequestration and microbial biomass and activity as well as crop yield compared with monocropping.

Published: May 2017

Background: Nosocomial infections caused by methicillin-resistant Staphylococci could lead to increased morbidity and mortality, but little is known about the prevalence of infections with these organisms in healthcare facilities and in the community in Tripoli. This study investigated the in vitro susceptibility of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase negative staphylococci (MRCNS) to antimicrobial agents, and determined the molecular characteristics of MRSA.

Methods: This is a retrospective observational study aiming at determining the prevalence and antibiotic resistance pattern of (MRSA) and (MRCNS) isolated from non-duplicated clinical specimens in Tripoli Central Hospital (TCH) between June 2013 and June 2014. Isolates were identified using standard laboratory procedures. Antimicrobial susceptibility tests were carried out by disk diffusion method and automated systems. DNA of the MRSA isolates was used for PCR to determine the molecular analysis.

Results: 218 isolates of Staphylococci were obtained, 71.6% were coagulase positive staphylococci (CPS) and 28.4% were coagulase negative staphylococci (CNS). 39.7% of CPS were MRSA, while 75.8% of CNS were MRCNS. The rates of hospital-acquired MRSA (HA-MRSA) and community-acquired MRSA (CA-MRSA) among MRSA isolates were 61.3% and 38.7% respectively. A similar trend was detected among MRCNS isolates, where 74.5% were HA-MRCNS and 25.5% were CA-MRCNS. All the MRSA and MRCNS isolates were susceptible (100%) to vancomycin, tigecycline, linezolid, quinupristin/dalfopristin, daptomycin and moxifloxacin. Generally, hospital-acquired strains showed higher resistance rates than community-acquired ones to the most commonly tested non-beta-lactam antibiotics. 35.5% of all staphylococcal isolates exhibited mecA+ gene and 12.9% expressed mecC+. Meanwhile, 38.7% of MRSA isolates harbored both mecA and mecC. However, 12.9% of MSSA isolates were negative for both mecA and mecC. The mecA gene was detectable in 59.1% and 40.9 % of HA-MRSA and CA-MRSA isolates respectively.

Conclusion: Hospital-acquired MRSA and MRCNS isolates had higher resistance rates to non-beta lactam antimicrobial drugs than the respective community-acquired isolates. This was shown by early detection of mecC gene among MRSA isolates.

Published: May 2017

El objetivo del presente trabajo fue evaluar la reacción a M. phaseolina de tres variedades experimentales y siete variedades de polinización libre del INIFAP, así como 14 híbridos comerciales de sorgo, con la finalidad de identificar variedades e híbridos que puedan presentar tolerancia o menor susceptibilidad a esta enfermedad. Los experimentos se establecieron en Culiacán, Sinaloa, México, durante los ciclos Primavera-Verano de 2010 y 2011, bajo condiciones de campo en temporal. Se utilizó un diseño de bloques al azar en cada experimento con tres repeticiones y un análisis combinado para los dos ciclos agrícolas. La parcela experimental consistió en inocular 10 plantas con mondadientes infectados del hongo. El análisis de varianza detecto diferencias significativas (p<0.05) en longitud de lesión ocasionada por el hongo entre años. En el ciclo 2010, se observó una longitud de lesión promedio significativamente mayor (10.10 cm) en comparación con el ciclo 2011 (5.79 cm). Los genotipos con menor longitud de lesión en promedio de los dos ambientes fueron: Fortuna y Mazatlán-16 (3.5 y 4.95 cm, respectivamente).  Los genotipos con mayor longitud de lesión fueron Kilate, G-STAR-7402 y G-STAR-7205 (13.2, 15.7 y 16.65 cm, respectivamente). No existió correlación entre la longitud de lesión y rendimiento de grano. Las variedades Fortuna y Mazatlán-16 mostraron menor daño a M. phaseolina, por lo cual se sugieren para siembras de temporal y como progenitores en la formación de híbridos de sorgo tolerantes a esta enfermedad.

La resistencia a los antibióticos por parte de las bacterias está provocando gran impacto negativo en la salud humana y en la producción animal. Actualmente,  Staphylococcus aureus es considerada dentro de los seis principales grupos bacterianos con mayores reportes de aparición de resistencia a nivel mundial. Por otro lado, durante décadas las plantas de uso medicinal han sido fuente importante de compuestos  bactericidas; sin embargo, también se ha empezado a documentar otras moléculas con otros mecanismos antimicrobianos, como es la inhibición de la percepción de quórum (anti-percepción de quórum (APQ)). En la medicina tradicional mexicana las hojas de  aguacate mexicano (Persea americana var drymifolia) han sido empleadas para tratar diversos padecimientos que involucran infecciones bacterianas, por lo que es factible contenga compuestos que posean efectos antioxidantes, bactericidas y APQ, que ayuden a combatir las infecciones de cepas resistentes. De tal manera, que el objetivo de esta investigación fue determinar el efecto de los polifenoles totales de las hojas de Persea americana var. drymifolia y su actividad APQ sobre cepas de S. aureus  resistentes a meticilina (MRSA). Métodos: Se obtuvieron los polifenoles presentes en las hojas de 18 cultivares de aguacate mexicano mediante extracción asistida por ultrasonido y fueron purificados en una columna de amberlita. Estos polifenoles fueron analizados funcionalmente y evaluados contra cepas de  S. aureus  MRSA para determinar su efecto APQ sobre el sistema denominado Agr.Resultados: Los polifenoles extraídos de las hojas de aguacate de raza mexicana exhiben una fuerte actividad bactericida. De los 18 cultivares probados, la variedad María Elena fue la que presentó el mayor efecto, exhibiendo una CMI de 116 μg∙mL-1 y un CMB de 133 μg∙mL-1 contra la cepa de MRSA μ3. Sin embargo, también logran inhibir los niveles  de expresión del operón agr (P2 y P3) con respecto al gen constitutivo de rDNA 16S. De igual manera, los polifenoles mostraron una buena actividad antioxidante, además de que se logró identificar la presencia de flavonoides y saponinas.Discusión y Conclusión: Los polifenoles extraídos de las hojas de aguacate mexicano, exhiben principalmente actividad bactericida, pero también inhiben la expresión de genes asociados a la percepción de quórum de cepas de S. aureus  MRSA. De igual manera, presentan una buena actividad antioxidante, lo que en conjunto puede ayudar a contrarrestar las infecciones con cepas resistentes de manera más eficiente. Por lo tanto, las hojas de aguacate mexicano son una fuente importante de metabolitos antioxidantes, bactericidas y APQ.

Metabolic syndrome is a frequent metabolic disorder characterized by obesity and insulin resistance seems to be the main pathophysiological alteration. The goal of treating metabolic syndrome is to reduce the risk of coronary heart disease and the development of type 2 diabetes. The lifestyle modification therapy combines specific recommendations on diet alone or combined with other strategies. In this review, we address the following topics: 1) the importance of the high prevalence of metabolic syndrome and obesity, and 2) the role of lifestyle modification focusing on dietary fat intake in the management of MS.

Published: May 2017

Patients with gallstones are often affected by alimentary disorders contributing to the onset of gallstones disease. Cholecystectomy can have nutritional and metabolic consequences in the short-term (diarrhea, abdominal pain and bloating) and in the long-term (increased Body Mass Index with metabolic syndrome, gastritis, liposoluble vitamin deficiency). Pathogenic mechanisms behind these disturbances are reviewed and the need for an early post-operative nutritional intervention based on low-lipid, high-fibers diet, is highlighted.
Hypertension and Risk of Post-Operative Cognitive Dysfunction (POCD): A Systematic Review and Meta-Analysis
Authors: Feinkohl I. , Winterer G. , Pischon T.
Published: May 2017

Background:

Post-operative cognitive dysfunction (POCD) occurs frequently after major surgery. Hypertension is well-established as a risk factor for age-related cognitive impairment, but it is unclear whether or not it also increases the risk of POCD.

Objective:

To evaluate the role of hypertension in POCD risk in a systematic review and meta-analysis.

Method:

PubMed, Ovid SP and the Cochrane Database of Systematic Reviews were searched for longitudinal studies of adults undergoing surgery with reporting of hypertension, blood pressure and/or anti-hypertensive treatment associations with POCD as relative risks or odds ratios. Fixed-effects meta-analyses were performed using Review Manager (version 5.3).

Results:

Twenty-four studies on 4317 patients (mean age 63 years) were included. None of the studies had set out to assess hypertension as a risk factor for POCD. Hypertension was used as a categorical predictor throughout and only 2 studies adjusted for potential confounders. Across all 24 studies, hypertension was not significantly associated with POCD risk (RR 1.01; 95% CI 0.93, 1.09;p=0.82), though among 8 studies with >75% males, we found hypertension associations with a 27% increased risk of POCD (RR 1.27, 95% CI 1.07, 1.49;p=0.005).

Conclusion:

Our findings do not support the hypothesis that hypertension is a risk factor for POCD. However, since none of the studies included in our analysis were hypothesis-driven and most did not adjust for potential confounders, further systematic investigations are needed to evaluate the role of hypertension in the epidemiology of POCD.

Choice Behaviour of Housing Attributes: Theory and measurement
Authors: Zinas Bako Zachariah , Mohd Jusan Mahmud
Published: May 2017

Preferences and choices in society are constant dynamic operations, made based on the behavioural dynamism of people. In this cosmic dynamism, they keep shifting from one stage to another, within the same cosmic space. Housing preferences and choices, like any other life interests, therefore operate within this framework. Unlike merchandised product brands, housing brands are hardly known, probably because of the heterogeneous nature of the housing product - the house. However, very little is known about the relevant housing attributes (refer to page 7). Housing preferences and choices operate within the framework of preferences and choices for housing attributes. In any preference and choice activity, there are underlying motivations that make it possible for an individual to choose from available alternatives within a given product field. This paper examines and outlines the methodological and theoretical framework of housing preferences and choices, based on the theory of means-end chain (MEC). Previous MEC applications in the field of architecture and urban design have been very useful and successful. The paper attempts to explore from the literature the possibility of extending the previous methods and their applicability in the design process. In dealing with user preference for housing, there is a need for research for the development of a technological tool to identify user needs and preferences, and the kind of decision support that is required to identify these needs.

Service Environment of Restaurants: Findings from the youth customers
Authors: Boo Ho Voon.
Published: May 2017

The relatively service-driven restaurant industry is becoming more important in generating income for many Asian countries and hence the service performance of the restaurants must be well understood and managed. The key determinants for restaurant service quality need to be identified, especially for the important segment such as youth customers. Therefore, this paper aims to explore the importance of service environment (servicescape and human service), food quality and price from the youth customers’ perspective. The types of restaurant investigated were the fine dining (n1 = 145), fast food (n2 = 147), and food court (n3 = 117) restaurants. Duly completed structured questionnaires (n = 409) were collected. The key determinants on satisfaction and loyalty were mainly human service and price. However, the impact of servicescape on customer satisfaction and loyalty was relatively smaller, except for fast food restaurants.

Authors: Jusoh Rohayati , Zainal Abidin Zubaidah
Published: May 2017

This paper presents a study of students‟ awareness, experiences and perceptions on teaching-research nexus in three universities in Malaysia, namely UiTM, UIA and UKM. The findings are based on the results of the questionnaires of 480 students. In line with the previous research, the results indicate that students are moderately aware of the research activities of their lecturers. Nevertheless, many of the students participating in this research perceive clear benefits to teaching and learning from the research activities undertaken at their university, their experiences on research aspects, and the academicians' involvement in research. The results of the study could be applied to the discussion of particular strategies that may be used to strengthen the nexus between teaching and research to benefit the undergraduates‟ learning experience in these institutions.

Authors: Lailiyah Masrurin , Cahyono Bambang Yudi
Published: May 2017

The advance of technology nowadays has encouraged many English as a Foreign Language (EFL) teachers to use technology in EFL teaching. However, some EFL teachers are still reluctant to take the opportunity. Low level of self-efficacy has been identified as a factor that hinders EFL teachers to use technology in EFL teaching. While a lot of research on EFL teachers’ self-efficacy has been reported in the literature, EFL teachers’ Self-Efficacy towards Technology Integration (SETI) has been rarely studied, especially in the Indonesian context of EFL teaching. Therefore, this study aimed to examine Indonesian EFL teachers’ SETI and their use of technology in EFL teaching. It involved 23 EFL teachers. Data were collected by using survey and interview. Analysis of the data showed that there is a relation between the EFL teachers’ SETI and their use of technology in EFL teaching.

Authors: Camargos Maria Gisely , Costa Maria de Lourdes Zamboni , Miranda Elisângela de Souza
Published: May 2017

O controle biológico aplicado consiste em liberações em massa de predadores ou parasitoides após a criação laboratorial em larga escala. Avaliar o custo de produção do parasitoide Diachasmimorpha longicaudata para controle biológico de moscas-das-frutas irá fornecer uma ferramenta capaz de auxiliar o planejamento, controle e uma forma de apoiar as empresas quanto as suas tomadas de decisão. Este trabalho teve por objetivo identificar e analisar os custos variáveis de produção do parasitoide D. longicaudata, criado em larvas de Anastrepha fraterculus. Para isso, foi utilizada a ferramenta de Custeio Baseado em Atividade [ABC]. Foi acompanhado o processo produtivo para obter o custo variável total de produção em laboratório de pesquisa e biofábrica de inimigos naturais, localizado em Piracicaba, São Paulo. A capacidade de produção de pupas de A. fraterculus parasitadas por D. longicaudata é de um milhão por semana nesse laboratório, sendo que um milhão de pupas representa 34 L, e um mL contém aproximadamente 30 pupas. O custo variável de produção para produzir um milhão de pupas parasitadas por semana foi de R$ 5.919,65. O custo com mão de obra representa 57% do custo total, enquanto o custo com materiais representa 43%. Portanto, o custo de uma pupa parasitada por D. longicaudata foi de R$ 0,0059 considerando um milhão de pupas por semana. A tomada de decisão do produtor em relação ao controle biológico utilizando D. longicaudata dependerá de estudos prévios sobre o parasitoide e cultura pretendida.
De la autonomía personal al consentimiento informado y las voluntades anticipadas
Authors: Martínez Bullé Goyri Víctor Manuel , Olmos Pérez Alexandra
Published: May 2017

En este trabajo se aborda cómo los individuos hemos logrado en los últimos tiempos el respeto a nuestra dignidad en el momento de la muerte, ejerciendo nuestra autonomía al asumir decisiones con relación a la manera en que queremos vivir el tránsito de la vida a la muerte, si bien no tomando el control sobre el momento mismo de la muerte, sí sobre las condiciones y la atención médica que deseamos nos sea proporcionada en ese momento. Desde el punto de vista jurídico se ha desarrollado la idea de que tratar a un paciente sin su consentimiento o pese a sus objeciones puede constituir una conducta antijurídica. Al derecho de la persona de autodeterminarse se corresponde el deber del médico de informar al paciente la verdad sobre su condición, los cursos de acción entre los cuales puede elegir, sus consecuencias, de manera que cuente con los medios para poder adoptar una decisión. El derecho a la información y al consentimiento informado se han desarrollado como un derecho autónomo, complementario al derecho a la salud. La doctrina del consentimiento informado dio lugar a que se empezara a reconocer el derecho que tenemos todos a tomar decisiones con respecto al final de nuestra propia vida. Vivir con dignidad ese momento significa, entre otras cosas, además de la eliminación del dolor y el sufrimiento, que se respete nuestra autonomía; esto es, nuestra voluntad sobre qué tipo de atención médica queremos recibir y hasta qué momento queremos recibirla. El paso siguiente sería encontrar el medio más adecuado para que esa voluntad pudiera expresarse, siendo que y es así como surgen las llamadas “voluntades anticipadas”, que actualmente forman ya parte del sistema jurídico mexicano en diversas entidades federativas, y lo cual ha llevado al desarrollo de un nuevo ámbito de servicios médicos para los pacientes terminales: los cuidados paliativos, que ya se encuentran previstos también a nivel federal en la Ley General de Salud.

Authors: Londoño Toro Beatriz
Published: May 2017

Este artículo forma parte de un trabajo de investigación que analiza el papel de las clínicas jurídicas en las universidades iberoamericanas. Tiene como objetivo presentar la percepción de los docentes clínicos y de los estudiantes sobre las necesidades, funciones y retos de las clínicas en la formación jurídica. Se inicia con una presentación conceptual e histórica, que permite diferenciar y reconocer la evolución del movimiento de educación legal clínica en Iberoamérica, para posteriormente evaluar el modelo en seis países (Argentina, Chile, Colombia, México, Perú y España). Se utilizó la metodología DOFA, a partir de la percepción de los docentes clínicos —obtenida a través la implementación de entrevistas en profundidad— y la percepción delos estudiantes que integran o han integrado clínicas jurídicas en Iberoamérica —a partir de una encuesta—. Finaliza el trabajo con unas conclusiones que buscan evidenciar los principales retos, y ante todo, la necesidad de reconsiderar y valorar la metodología de educación legal clínica como una herramienta pedagógica integral.
