Traducir el Martín Fierro, una credencial cultural para Folco Testena
Authors: Iriarte Sara Jaquelina 
Published: May 2020

En los intersticios entre literatura y vida, Folco Testena forja su autofiguración de traductor en la introducción al Martín Fierro que preparó para acompañar su primera versión al italiano de la obra de José Hernández. Su relato en primera persona revela lo íntimo a la vez que da cuenta de las coyunturas sociohistóricas que marcaron la labor intelectual desarrollada por los inmigrantes en la cosmopolita Buenos Aires de principios del siglo XX. Traducir el Martín Fierro se presenta, bajo la forma de una historia de autosuperación, como la oportunidad para obtener una credencial cultural en un medio de hostilidad al extranjero y de censura política. El objetivo del presente artículo es poner en circulación un texto de difícil acceso y contribuir a completar el cuadro de la historia de la traducción poniendo en foco a los sujetos sociales que la protagonizan.

Abstract. Here we describe the design and performance of a new
water cluster chemical ionization–atmospheric pressure interface time-of-flight mass spectrometer (CI-APi-TOF). The instrument selectively measures
trace gases with high proton affinity such as ammonia and dimethylamine,
which are important for atmospheric new particle formation and growth.
Following the instrument description and characterization, we demonstrate
successful measurements at the CERN CLOUD (Cosmics Leaving OUtdoor Droplets)
chamber where very low ammonia background levels of ∼4 pptv
were achieved (at 278 K and 80 % RH). The limit of detection of the water
cluster CI-APi-TOF is estimated to be ∼0.5 pptv for ammonia.
Although no direct calibration was performed for dimethylamine (DMA), we
estimate its detection limit is at least 3 times lower. Due to the short
ion–molecule reaction time and high reagent ion concentrations, ammonia
mixing ratios up to at least 10 ppbv can be measured with the instrument
without significant reagent ion depletion. Besides the possibility to
measure compounds like ammonia and amines (dimethylamine), we demonstrate
that the ionization scheme is also suitable for the measurement of trace
gases containing iodine. During CLOUD experiments to investigate the
formation of new particles from I2, many different iodine-containing
species were identified with the water cluster CI-APi-TOF. The compounds
included iodic acid and neutral molecular clusters containing up to
four iodine atoms. However, the molecular structures of the
iodine-containing clusters are ambiguous due to the presence of an unknown
number of water molecules. The quantification of iodic acid (HIO3)
mixing ratios is performed from an intercomparison with a nitrate
CI-APi-TOF. Using this method the detection limit for HIO3 can be
estimated as 0.007 pptv. In addition to presenting our measurements obtained
at the CLOUD chamber, we discuss the applicability of the water cluster
Ci-APi-TOF for atmospheric measurements.

Published: May 2020

Introduction:
Insurance claim rejections represent a challenge for healthcare providers because of the potential for lost revenue and administrative costs of reworking claims.

Methods:
The billing records of five hand and upper extremity surgeons at a tertiary academic center were queried for all patient billing activity over a 1-year period yielding a total of 14,421 unique patient encounters.

Results:
A total of 11,839 unique patient encounters were included, and the overall claim rejection rate was 19.3%. Claim rejection rate varied significantly by payer (P < 0.0001) and was lowest in private insurance (14.0%) and highest in Medicare (31.2%). The use of multiple Current Procedure Terminology codes for an encounter was independently associated with an increased risk of claim rejection for both office (25.6%, relative risk [RR] 1.27, 95% confidence interval [CI] 1.03 to 1.49, P = 0.0032) and surgical (25.6%, RR 1.67, 95% CI 1.28 to 2.18, P = 0.0002) settings. After multivariate regression adjustment, modifier 25 was associated with a decreased risk of claim rejection (23.3%, RR 0.72, 95% CI 0.61 to 0.85, P < 0.0001).

Discussion:
Insurance claim rejection occurs frequently (19.3%) in hand/upper extremity surgery and varies by insurance type, with the highest rejection rate occurring in Medicare (31.2%). For a given encounter, the use of multiple Current Procedure Terminology codes and specific modifiers are predictive of rejection risk.

Preoperative Carbohydrate Drinks Do Not Decrease Postoperative Nausea and Vomiting in Type 2 Diabetic Patients Undergoing Total Knee Arthroplasty—A Randomized Controlled Trial
Authors: Shin Seokyung , Choi Yong Seon , Shin Hyejung , Yang Ick Hwan , Park Kwan Kyu , Kwon Hyuck Min , Kang Byunghag , Kim So Yeon 
Published: May 2020

Introduction:
We evaluated whether preoperative carbohydrate drink would be able to decrease postoperative nausea and vomiting (PONV) and improve the quality of recovery (QoR) in diabetic patients undergoing total knee arthroplasty (TKA).

Methods:
Eighty-two patients were randomized to either the intravenous (IV) Dextrose group (n = 41) or Oral carbohydrate (CHO) group (n = 41). The IV Dextrose group received dextrose solution mixed with insulin while fasting, and the Oral CHO group received carbohydrate drinks preoperatively. PONV was assessed up to postoperative 36 hours, and QoR was assessed before surgery and on postoperative day (POD) 1. Blood glucose was measured from the morning of surgery until POD 1.

Results:
PONV scores were not different between the groups. Postoperative QoR scores were significantly higher in the Oral CHO group (median [interquartile range]; 160 [153 to 167]) than the IV Dextrose group (155 [147 to 159]) (P = 0.009), but the difference did not meet the minimal clinically important difference. Blood glucose was comparable between the groups.

Discussion:
Preoperative CHO drink did not reduce PONV in diabetic patients after total knee arthroplasty. A statistically significant but clinically questionable improvement in the QoR was seen in the Oral CHO group. However, preoperative CHO drink did not increase hyperglycemia, which suggests that it may be a safe component of perioperative care in diabetic patients.

Published: May 2020

Introduction:
There are few small case series that discuss patient outcomes after a transolecranon fracture-dislocation, and they suggest that patients have reasonable function after injury. The purpose of this study was to describe the injury pattern and clinical outcomes of transolecranon fracture-dislocations.

Methods:
After Institutional Review Board approval, transolecranon fracture-dislocations treated at two academic level 1 trauma centers between 2005 and 2018 were retrospectively reviewed. Fracture characteristics and postsurgical complications were recorded. Radiographs were reviewed for arthrosis, and Quick Disabilities of Arm, Shoulder, and Hand (QuickDASH) scores were obtained at a minimum of 12 months after injury.

Results:
Thirty-five patients with a mean follow-up of 28 months (range, 12 to 117 months) were included. Nine patients had associated radial head fracture, 23 patients had associated coronoid fracture, four patients had ligamentous injury, and two patients had capitellum fracture. Four patients (11%) developed infection and required irrigation and débridement with intravenous antibiotics. Thirteen patients (13 of 35, 37%) developed radiographic arthrosis with most (11 of 13) having grade 2 or three changes. Patients who had associated radial head fracture, coronoid fracture, capitellum fracture, and/or ligamentous injury had significant arthrosis (10 of 24, 42%) more commonly than patients with olecranon fracture alone (1 of 11, 9%) (P = 0.05). Twenty-eight patients completed patient outcomes instrument and achieved a mean QuickDASH score of 9 (range, 0 to 59). Patients with isolated transolecranon fracture had a significantly better QuickDASH score (0.93, 0 to 4) than patients with transolecranon fracture variant with associated coronoid fracture, radial head fracture, distal humeral fracture, or ligamentous injury (11.74, 0 to 59) (P = 0.04).

Discussion:
Patients with transolecranon fracture-dislocation had excellent return to function based on the QuickDASH outcome assessment. Patients with transolecranon fracture with associated radial head fracture, coronoid fracture, humeral condyle fracture, and/or ligamentous injury tend to have worse functional outcome than patients with simple transolecranon fracture.

Elaboración y resignificación del álbum familiar a través del proyecto de creación en el duelo.
Authors: Morcate Casera Montse 
Published: May 2020

La fotografía doméstica, con el álbum como símbolo del legado de la memoria familiar, ha constituido el reflejo de la construcción identitaria y del deseo por configurar una memoria visual en la que proyectar una visión idealizada de la familia. Sin embargo, en otros periodos, las imágenes que reflejaban la muerte, el dolor o la pérdida del entorno fueron aceptadas como parte importante de la memoria familiar. A pesar de que en la actualidad este ámbito de representación se está volviendo a hacer visible, especialmente en el terreno online, es a través del proyecto de creación como numerosos artistas hablan del duelo, la enfermedad o la muerte, visibilizándolos y normalizándolos. En este sentido, el artículo plantea como objeto de estudio dos posibles aproximaciones de este tipo de obras en los que se distingue la documentación de unnuevo episodio de la historia familiar frente a la deconstrucción y/o resignificado del propio archivo familiar. Este examen se complementa con el análisis de diversos proyectos de creación de la autora en los que se explora la memoria y la pérdida a través de la autorrepresentación y la transformación del álbum y la imagen familiar, tanto desde la teoría como en la práctica artística.
Domestic photography, with the album as the symbol of the legacy of family memory, has been a reflection of the identity construction and the desire to configure a visual memory in which to project an idealized vision of the family. However, in other periods, images that reflected personal pain, loss or death were accepted as an important part of family memory. Although this field of representation is now becoming visible, especially in the online ground, it is through the art project that many artists talk about grief, disease or death, making these issues visible and normalizing them. In this sense, the object of study here proposed is to analyze two possible approaches in which one documents a new chapter of the family album whereas the second deconstructs and/or resignifies the actual family archive. Along with this proposal various projects by the author are presented in which memory and loss are explored through self-representation and the transformation of the album and the family image, both from theory and artistic practice.
Material sensible. Un proyecto de fotografía participativa que muestra la experiencia de personas que han sufrido abusos sexuales en la infancia.
Authors: Plans Farrero Mireia 
Published: May 2020

Material sensible es un proyecto de fotografía participativa con personas que han sufrido abusos sexuales en la infancia y que están recibiendo apoyo terapéutico. El proyecto está basado en la metodología Punt de Vista que utiliza la fotografía como herramienta de transformación personal e inclusión social, dirigida a colectivos y personas en riesgo de vulnerabilidad social, poco visibles en discursos hegemónicos. A través del acompañamiento y la inmersión en un proceso creativo que utiliza la intimidad como fuente de referencia, se articulan relaciones entre imagen, memoria, identidad, cotidianidad y representación. Cada participante recupera emociones y fragmentos de su historia personal -a menudo silenciada- reconstruyendo una narración visual propia. El proyecto finaliza con una exposición colectiva fruto del proceso de creación de cada participante, que ayuda a reforzar la identidad, generar nuevos relatos y concienciar a la sociedad sobre un tema tabú como es el abuso sexual infantil.
Material sensible is a participatory photography project with people who have been sexually abused in their childhood and receive therapeutic support. The project is based on the Punt de Vista methodology, using photography as a tool for personal transformation and social inclusion, aimed at groups and people at risk of social vulnerability, which are not visible in predominant discourses. Through accompaniment and immersion in a creative process that uses intimacy as a reference, it connects image, memory, identity, everyday life and representation. Each participant recovers emotions and fragments of their personal history - often silenced - by reconstructing their own visual narrative. The project ends with a collective exhibition resulting from the creative process of each participant, which helps to strengthen the identity, generate new stories and raise awareness.of an unspoken subject such as child sexual abuse.
The ability of oriental magpies (Pica serica) to solve baited multiple-string problems
Authors: Wang Lin , Guo Jinxin , Tian Heng jiu , Sui Jinling 
Published: May 2020

Background
Baited multiple-string problems are commonly used in avian laboratory studies to evaluate complex cognition. Several bird species possess the ability to use a string pull for obtaining food.

Methods
We initially tested and trained 11 magpies to determine whether the oriental magpie (Pica sericia) possesses the ability to solve baited multiple-string problems. Eight of the birds obtained the bait by pulling, and were selected for formal multiple-string tasks in the second stage. Second stage tests were divided into seven tasks based on string configurations.

Results
Only two magpies were able to solve two tasks: one solved the task of parallel strings, and the other solved the task of slanted strings with the bait farther from the middle point between the two strings and selected the short string in the task of long-short strings. When faced with more difficult tasks (i.e., the task of slanted strings with the bait closer to the middle point between the two strings, the task with two crossing strings, and the task of continuity and discontinuity), the birds initially observed the tasks and chose instead to adopt simpler strategies based on the proximity principle, side bias strategies and trial-and-error learning. Our results indicate that the oriental magpie had a partial understanding of the principle of multiple-string problems but adopted simpler strategies.

Jury simulation studies: To exclude or not to exclude participants based on a lack of comprehension of the case?
Authors: Cullen Hayley J. , Monds Lauren A. 
Published: May 2020

SummaryJury simulation research has been the subject of longstanding criticism in regards to ecological validity. One additional factor that has received little attention that may also impact the generalizability of this research relates to excluding participants based on their memory of, or their attention paid to, the case. In order to determine how common this exclusion is, the authors conducted a scoping review of jury simulation studies within the last 10 years across three major legal psychology journals. The review revealed variability in if and how studies excluded on the basis of poor attention or for failing manipulation or general memory checks. In addition, studies that did exclude on this basis varied greatly in the proportion of the sample that was excluded. Recommendations are provided in order to assist jury researchers in future with how best to manage exclusions on the basis of juror memory and attention.
Basal Plane Hydrogen Evolution Activity from Mixed Metal Nitride MXenes Measured by Scanning Electrochemical Microscopy

Published: May 2020

Abstract2D early transition metal carbide and nitride MXenes have intriguing properties for electrochemical energy storage and electrocatalysis. These properties can be manipulated by modifying the basal plane chemistry. Here, mixed transition metal nitride MXenes, M‐Ti4N3Tx (M = V, Cr, Mo, or Mn; Tx = O and/or OH), are developed by modifying pristine exfoliated Ti4N3Tx MXene with V, Cr, Mo, and Mn salts using a simple solution‐based method. The resulting mixed transition metal nitride MXenes contain 6–51% metal loading (cf. Ti) that exhibit rich electrochemistry including highly tunable hydrogen evolution reaction (HER) electrocatalytic activity in a 0.5 m H2SO4 electrolyte as follows: V‐Ti4N3Tx > Cr‐Ti4N3Tx > Mo‐Ti4N3Tx > Mn‐Ti4N3Tx > pristine Ti4N3Tx with overpotentials as low as 330 mV at −10 mA cm−2 with a charge‐transfer resistance of 70 Ω. Scanning electrochemical microscopy (SECM) reveals the electrochemical activity of individual MXene flakes. The SECM data corroborate the bulk HER activity trend for M‐Ti4N3Tx as well as provide the first experimental evidence that HER results from catalysis on the MXene basal plane. These electrocatalytic results demonstrate a new pathway to tune the electrochemical properties of MXenes for water splitting and related electrochemical applications.
Biodegradable Polymers as the Pivotal Player in the Design of Tissue Engineering Scaffolds
Authors: Zhang Fan , King Martin W. 
Published: May 2020

AbstractBiodegradable polymers play a pivotal role in in situ tissue engineering. Utilizing various technologies, researchers have been able to fabricate 3D tissue engineering scaffolds using biodegradable polymers. They serve as temporary templates, providing physical and biochemical signals to the cells and determining the successful outcome of tissue remodeling. Furthermore, a biodegradable scaffold also presents the fourth dimension for tissue engineering, namely time. The properties of the biodegradable polymer change over time, presenting continuously changing features during the degradation process. These changes become more complicated when different materials are combined together to fabricate a composite or heterogeneous scaffold. This review undertakes a systematic analysis of the basic characteristics of biodegradable polymers and describe recent advances in making composite biodegradable scaffolds for in situ tissue engineering and regenerative medicine. The interaction between implanted biodegradable biomaterials and the in vivo environment are also discussed, including the properties and functional changes of the degradable scaffold, the local effect of degradation on the contiguous tissue and their evaluation using both in vitro and in vivo models.

AbstractThere is a need for improved nanomaterials to simultaneously target cancer cells and avoid non‐specific clearance by phagocytes. An ellipsoidal polymersome system is developed with a unique tunable size and shape property. These particles are functionalized with in‐house phage‐display cell‐targeting peptide to target a medulloblastoma cell line in vitro. Particle association with medulloblastoma cells is modulated by tuning the peptide ligand density on the particles. These polymersomes has low levels of association with primary human blood phagocytes. The stealth properties of the polymersomes are further improved by including the peptide targeting moiety, an effect that is likely driven by the peptide protecting the particles from binding blood plasma proteins. Overall, this ellipsoidal polymersome system provides a promising platform to explore tumor cell targeting in vivo.
