The riddle of hyperlactatemia

A recent observational study in a large cohort of critically ill patients confirms the association between hyperlactatemia and mortality. The mechanisms regulating the rates of lactate production and clearance in critical illness remain poorly understood. During exercise, hyperlactatemia clearly results from an imbalance between oxygen delivery and energy requirements. In critically ill patients, the genesis of hyperlactatemia is significantly more complex. Possible mechanisms include regional hypoperfusion, an inflammation-induced upregulation of the glycolitic flux, alterations in lactate-clearing mechanisms, and increases in the work of breathing. Understanding how these complex processes interact to produce elevations in lactate continues to be an important area of research

Benefits and Challenges of Support Facilitation in an Inclusive Classroom

The purpose of this inquiry was to determine the benefits and challenges of support facilitation in an inclusive classroom. To answer our inquiry questions, we (UNF ESE teacher candidates) collected data on general education (GE) teachers and the varying exceptional (VE) teachers’ perceptions of support facilitation at Coastal Middle School through surveys, observational walkthroughs, and teacher interviews. From the data, we discovered benefits and challenges in four overarching categories: teachers’ perceptions, collaboration, instruction, and student engagement themes. As a result of the data, we recommended that Coastal Middle School outline clear and explicit roles for both the GE teacher and the special education teacher during the co-planning and co-teaching process, train the teachers on how to co-plan together, inform them of co-teaching methods they can use, and to create a schedule where the VE teacher only needs to focus on one class during each period

Plant bugs (Heteroptera: Miridae) associated with roadside habitats in Argentina and Paraguay: Host plant, temporal, and geographic range effects

Between November 1999 and September 2001, mirid nymphs (Hemiptera: Miridae) were collected on wild and cultivated plants in central and northern Argentina and southeastern Paraguay. In the laboratory, nymphs were reared until adult emergence. Four (Bryocorinae, Deraeocorinae, Mirinae, and Orthotylinae) of the eight mirid subfamilies were collected during the study. Twenty-two mirid species on 43 putative host plant species were collected in Argentina, and five species of mirids on eight plant species were collected in Paraguay. Eighty-five new mirid-plant associations were recorded (only 112 mirid-plant associations had been reported previously for Argentina). Most of the mirids were in the subfamily Mirinae, tribe Mirini, and most of the host plants belonged to Asteraceae. Almost all mirids were collected on plants with flower buds present. In addition to host plant records, the phenology and pattern of plant use for the most abundant mirids are reported. Mirid richness and abundance varied according to the host plant species; the highest diversity and richness of mirids occurred in the western region of Argentina (Salta, Jujuy, and Tucumán provinces). The most frequently collected mirid, Taylorilygus apicalis (Fieber) (≈87% of the 35,970 collected mirids), was usually collected on Asteraceae. This exotic species could have affected the native mirid fauna in the study area. More research on the possible interactions between T. apicalis and the native mirids of Argentina and Paraguay is needed. Our results suggest that T. apicalis exhibits regional polyphagy, i.e., uses numerous hosts throughout its geographic range.Facultad de Ciencias Naturales y Muse

The role of the provincial state in the construction of a “chubutense identity”: representations of aboriginal and Welsh peoples in school texts in Chubut (1978 – 2012)

El siguiente escrito responde a los avances iniciales en mi investigación de tesis doctoral en historia, en la que planteo trabajar la construcción de identidades a partir de lo que implica “ser chubutense”, especialmente desde las acciones del gobierno provincial desde la creación de la provincia del Chubut en el periodo 1955-1958. Aquí analizaremos específicamente como son trabajadas las historias de los pueblos originarios de la región y los galeses en los textos escolares de la provincia, en el periodo 1980-2012, es decir, desde su surgimiento hasta la actualidad.The following essay reflects the initial advances regarding my PhD thesis research, in which I propose to enquire about the construction of identities based on what it implies to be “chubutense”, especially from the actions of the provincial government since the creation of Chubut province in the period 1955-1958. Here, we will specifically analyze the approach of the history of the natives and the Welsh in provincial school textbooks, in the period 1980-2012, that is, from their emergence to the present.Fil: Williams, Jose Guillermo.

La construcción del pasado chubutense en el discurso histórico provincial: representaciones de la experiencia exploratoria y colonizadora española en Chubut, Argentina, en textos escolares provinciales (1978-2006)

The following paper proposes to analyze the ways in which Chubut school textbooks have represented the Spanish exploratory and colonizing experience in the current territory of Chubut, Argentina. We start the article by explaining the role of education and school textbooks in the conformation of a territory’s history and identity, and then we briefly refer to the role played by “Hispanity” in the nation and the province, especially since the early 20th century, but also in current time. After describing what we call the “Spanish experience” in Chubut, we analyze five school textbooks, seeing how this experience is represented in each of them. The article ends by explaining that the assigned role varies between one text and the other but, despite its continuous appearance, its importance never manages to be bigger than other historical episodes of Chubut, chiefly, the Welsh settlement. En este trabajo nos proponemos analizar de qué modo se ha representado la experiencia exploratoria y colonizadora española en el territorio de la actual provincia de Chubut, Argentina, en los textos escolares de educación primaria de producción provincial. Para ello iniciamos el artículo explicando el rol de la educación y los textos escolares en la conformación de la historia y la identidad de un territorio, y luego nos referimos brevemente al papel que ha jugado la “hispanidad” en la nación y en la provincia, especialmente desde principio del siglo XX, pero también en la actualidad. Tras una descripción de lo que denominamos la “experiencia española” en Chubut, analizamos cinco textos escolares, viendo cómo esta experiencia es representada en cada uno de ellos. El artículo finaliza explicando que el rol asignado va variando entre un texto y en otro, pero, a pesar de aparecer siempre, su papel nunca llega a ser más relevante que otros episodios históricos de la provincia, principalmente el de la colonización galesa

An Exploratory Study to Understand Factors Associated with Health-related Quality of Life Among Uninsured/Underinsured Patients as Identified by Clinic Providers and Staff

Since the release of Healthy People 2020, there has been extensive research understanding factors associated with health-related quality of life (HRQoL) among specific populations. Despite this growing body of research, little has been conducted to understand the factors associated with HRQoL among uninsured/underinsured Americans. The purposes of the present study were to assess clinic staff to determine: (1) whether there is a need to examine HRQoL among uninsured/underinsured individuals, (2) whether there is a need for tailored HRQoL-promoting interventions among uninsured/underinsured individuals, and (3) the factors associated with HRQoL among uninsured/underinsured individuals. A survey was sent to an association of 41 clinics that provides free medical services to uninsured/underinsured individuals. The majority of participants indicated that uninsured/underinsured individuals experience unique factors associated with HRQoL and that there was a need to implement tailored HRQoL-improving interventions among uninsured/underinsured individuals. The results also present the personal/contextual factors associated with HRQoL of uninsured/underinsured individuals
