Aspectos de la política económica kirchnerista

Este trabajo presentar algunas preguntas en torno a la política económica del gobierno kirchnerista. La pregunta que atraviesa el mismo es la de si posible hablar de una alianza o articulación entre ciertas fracciones de capital y sectores del trabajo, impulsada y mediada por el gobierno. Para responder a este interrogante, en un primer lugar se describe brevemente en qué consistió el modelo nacional-popular de sustitución de importaciones, como también el modelo neoliberal en Argentina. Luego se centra en la descripción de las políticas económicas del gobierno de Néstor Kirchner, con el objetivo de observar continuidades y rupturas respecto al modelo neoliberal, e ir detectando indicadores que puedan responder a la pregunta formulada. Serán tomadas las convocatorias al Consejo del Salario Mínimo, Vital y Móvil, como espacio que pone en juego las relaciones entre los trabajadores y empresarios locales, como también se analizará el rol del gobierno en el mismo. Finalmente, se formularán algunas preguntas en torno al llamado diálogo o pacto social propuesto por el gobierno de Cristina Fernández de Kirchner, entendiéndolo como un aspecto que daría continuidad a los debates instalados en el marco del Consejo del Salario. La intención de este trabajo es la de conocer y realizar un análisis de la política económica, generar interrogantes, detectar tendencias y condiciones; a fin de enriquecer la mirada sobre el momento socio-histórico en el que nos encontramos.

Estructura de clase, distribución del ingreso y políticas públicas. Una aproximación al caso argentino en la etapa post-neoliberal

En el período 2003-2009 parecieran reducirse en Argentina los niveles de desigualdad de ingresos respecto de la década de 1990. En ocasiones, dicha dinámica distributiva suele relacionarse a ciertas políticas públicas aplicadas por el Estado. Sin embargo, creemos que, generalmente, estos análisis no contemplan el impacto diferenciado de las políticas de ingresos -tales como el Salario Mínimo vital y Móvil, la Asignación Universal por Hijo, el Plan Jefes, el Plan Familias, entre otras- sobre los trabajadores que pertenecen a diferentes estratos al interior de los sectores populares. En el presente trabajo, intentamos realizar una estratificación social por clases sociales, similar a la propuesta por Torrado (1994), para evaluar dos cuestiones clave en relación a las políticas de ingresos aplicadas en la última década. Primero, pretendemos medir el impacto diferencial de las políticas mencionadas sobre los diferentes estratos al interior de los sectores populares. En segundo lugar, la estratificación mencionada nos permite indagar sobre el origen de estas políticas públicas y en qué medida las mismas son el resultado de las estrategias de lucha de los diferentes estratos que conforman las clases populares. La fuente de información prioritaria para realizar el estudio será la Encuesta Permanente de Hogares diseñada por el INDEC

Constitucionalismo contemporáneo y la teoría del contenido mínimo: el derecho al trabajo

El neoconstitucionalismo, como modelo de teoría jurídica, permite entender y abordar de mejor forma la estructura del derecho en el siglo XXI, superando así los rezagos del derecho privado, insuficiente en estos tiempos para explicar en clave de derechos la relación entre Constitución, Estado y derechos humanos. En este libro se aborda la teoría del contenido mínimo de los derechos fundamentales, según la cual estos tienen, además del contenido esencial, uno que está dado por los instrumentos internacionales y que representa el estándar mínimo que los Estados no pueden desconocer bajo ninguna circunstancia so pena de eliminar o anular el derecho mismo y con ello dar lugar a responsabilidades internacionales. Esta teoría es aplicable también a los derechos sociales, por lo que, al analizar el derecho al trabajo, se busca ejemplificar de qué manera los Estados pueden, y deben, empezar a recorrer el camino de realización de ciertos derechos tradicionalmente relegados. Para ello se realiza un recorrido sobre el contenido y transformaciones del trabajo –como hecho social vital para las sociedades modernas– y se presenta una propuesta de contenido mínimo acorde con la normatividad internacional vigente.

Genetic evidence for the vital function of osterix in cementogenesis

To date, attempts to regenerate a complete tooth, including the critical periodontal tissues associated with the tooth root, have not been successful. Controversy still exists regarding the origin of the cell source for cellular cementum (epithelial or mesenchymal). This disagreement may be partially due to a lack of understanding of the events leading to the initiation and development of the tooth roots and supportive tissues, such as the cementum. Osterix (OSX) is a transcriptional factor essential for osteogenesis, but its role in cementogenesis has not been addressed. In the present study, we first documented a close relationship between the temporal- and spatial-expression pattern of OSX and the formation of cellular cementum. We then generated 3.6 Col 1-OSX transgenic mice, which displayed accelerated cementum formation vs. WT controls. Importantly, the conditional deletion of OSX in the mesenchymal cells with two different Cre systems (the 2.3 kb Col 1 and an inducible CAG-CreER) led to a sharp reduction in cellular cementum formation (including the cementum mass and mineral deposition rate) and gene expression of dentin matrix protein 1 (DMP1) by cementocytes. However, the deletion of the OSX gene after cellular cementum formed did not alter the properties of the mature cementum as evaluated by backscattered SEM and resin-cast SEM. Transient transfection of Osx in the cementoblasts in vitro significantly inhibited cell proliferation and increased cell differentiation and mineralization. Taken together, these data support 1) the mesenchymal origin of cellular cementum (from PDL progenitor cells); 2) the vital role of OSX in controlling the formation of cellular cementum; and 3) the limited remodeling of cellular cementum in adult mice.

The effect of implementing a modified early warning scoring (MEWS) system on the adequacy of vital sign documentation

Introduction and objectives Early recognition of deteriorating patients results in better patient outcomes. Modified early warning scores (MEWS) attempt to identify deteriorating patients early so timely interventions can occur thus reducing serious adverse events. We compared frequencies of vital sign recording 24 h post-ICU discharge and 24 h preceding unplanned ICU admission before and after a new observation chart using MEWS and an associated educational programme was implemented into an Australian Tertiary referral hospital in Brisbane. Design Prospective before-and-after intervention study, using a convenience sample of ICU patients who have been discharged to the hospital wards, and in patients with an unplanned ICU admission, during November 2009 (before implementation; n = 69) and February 2010 (after implementation; n = 70). Main outcome measures Any change in a full set or individual vital sign frequency before-and-after the new MEWS observation chart and associated education programme was implemented. A full set of vital signs included Blood pressure (BP), heart rate (HR), temperature (T°), oxygen saturation (SaO2) respiratory rate (RR) and urine output (UO). Results After the MEWS observation chart implementation, we identified a statistically significant increase (210%) in overall frequency of full vital sign set documentation during the first 24 h post-ICU discharge (95% CI 148, 288%, p value <0.001). Frequency of all individual vital sign recordings increased after the MEWS observation chart was implemented. In particular, T° recordings increased by 26% (95% CI 8, 46%, p value = 0.003). An increased frequency of full vital sign set recordings for unplanned ICU admissions were found (44%, 95% CI 2, 102%, p value = 0.035). The only statistically significant improvement in individual vital sign recordings was urine output, demonstrating a 27% increase (95% CI 3, 57%, p value = 0.029). Conclusions The implementation of a new MEWS observation chart plus a supporting educational programme was associated with statistically significant increases in frequency of combined and individual vital sign set recordings during the first 24 h post-ICU discharge. There were no significant changes to frequency of individual vital sign recordings in unplanned admissions to ICU after the MEWS observation chart was implemented, except for urine output. Overall increases in the frequency of full vital sign sets were seen.

Understanding dementia is vital in all health care staff

As the Australian population continues to age, health care staff will come into contact with and care for increasing numbers of people with dementia. A basic understanding of dementia is important to the quality of these interactions. This article summarises recently published research on levels of knowledge of Alzheimer’s disease among health care staff in an Australian regional health district (Smyth, Fielding, Beattie, Gardiner, Moyle, Franklin, Hines & MacAndrew, 2013).

Putting vital stains in context

While vital staining remains a cornerstone in the diagnosis of ocular disease and contact lens complications, there are many misconceptions regarding the properties of commonly used dyes by eye-care practitioners and what is and what is not corneal staining after instillation of sodium fluorescein. Similarly, the proper use and diagnostic utility of rose Bengal and lissamine green B, the other two ophthalmic dyes commonly used for assessing ocular complications, have similarly remained unclear. Due to the limitations of vital stains for definitive diagnosis, concomitant signs and symptoms in addition to a complete patient history are required. Over the past decade, there have been many reports of a type of corneal staining—often referred to as solution-induced corneal staining (SICS)—that is observed with the use of multipurpose solutions in combination with soft lenses, more specifically silicone hydrogel lenses. Some authors believe that SICS is a sign of lens/solution incompatibility; however, new research shows that SICS may be neither a measure of lens/solution biocompatibility nor ‘true’ corneal staining, as that observed in pathological situations. A large component of SICS may be a benign phenomenon, known as preservative-associated transient hyperfluorescence (PATH). There is a lack of correlated signs and/or symptoms with SICS/PATH. Several properties of SICS/PATH, such as appearance and duration, differentiate it from pathological corneal staining. This paper reviews the properties of vital stains, their use and limitations in assessment of the ocular surface, the aetiology of corneal staining, characteristics of SICS/PATH that differentiate it from pathological corneal staining and what the SICS/PATH phenomenon means for contact lens-wearing patients.

A response to "Re: Putting vital stains in context" by Charles W McMonnies, published in the same issue of this journal. "I thank Professor McMonnies for his thoughtful comments,1 which rightly forcemeto more directly address the clinical ramifications of solution-induced corneal staining (SICS). I concur with his observation that determining whether the staining can be attributed to preservative-associated transient hyperfluorescence (PATH) or true pathology can be difficult in a typical clinical situation, perhaps requiring two visits in a single day. There is no easy answer to this dilemma..."

The primacy of vital signs – Acute care nurses’ and midwives’ use of physical assessment skills: A cross sectional study

BACKGROUND: Registered nurses and midwives play an essential role in detecting patients at risk of deterioration through ongoing assessment and action in response to changing health status. Yet, evidence suggests that clinical deterioration frequently goes unnoticed in hospitalised patients. While much attention has been paid to early warning and rapid response systems, little research has examined factors related to physical assessment skills. OBJECTIVES: To determine a minimum data set of core skills used during nursing assessment of hospitalised patients and identify nurse and workplace predictors of the use of physical assessment to detect patient deterioration. DESIGN: The study used a single-centre, cross-sectional survey design. SETTING and PARTICIPANTS: The study included 434 registered nurses and midwives (Grades 5-7) involved in clinical care of patients on acute care wards, including medicine, surgery, oncology, mental health and maternity service areas, at a 929-bed tertiary referral teaching hospital in Southeast Queensland, Australia. METHODS: We conducted a hospital-wide survey of registered nurses and midwives using the 133-item Physical Assessment Skills Inventory and the 58-item Barriers to Registered Nurses’ Use of Physical Assessment scale. Median frequency for each physical assessment skill was calculated to determine core skills. To explore predictors of core skill utilisation, backward stepwise general linear modelling was conducted. Means and regression coefficients are reported with 95% confidence intervals. A p value < .05 was considered significant for all analyses. RESULTS: Core skills used by most nurses every time they worked included assessment of temperature, oxygen saturation, blood pressure, breathing effort, skin, wound and mental status. Reliance on others and technology (F = 35.77, p < .001), lack of confidence (F = 5.52, p = .02), work area (F = 3.79, p = .002), and clinical role (F = 44.24, p < .001) were significant predictors of the extent of physical assessment skill use. CONCLUSIONS: The increasing acuity of the acute care patient plausibly warrants more than vital signs assessment; however, our study confirms nurses’ physical assessment core skill set is mainly comprised of vital signs. The focus on these endpoints of deterioration as dictated by early warning and rapid response systems may divert attention from and devalue comprehensive nursing assessment that could detect subtle changes in health status earlier in the patient's hospitalisation.

Structural Integrity of the Greek Key Motif in beta gamma-Crystallins Is Vital for Central Eye Lens Transparency

Background: We highlight an unrecognized physiological role for the Greek key motif, an evolutionarily conserved super-secondary structural topology of the beta gamma-crystallins. These proteins constitute the bulk of the human eye lens, packed at very high concentrations in a compact, globular, short-range order, generating transparency. Congenital cataract (affecting 400,000 newborns yearly worldwide), associated with 54 mutations in beta gamma-crystallins, occurs in two major phenotypes nuclear cataract, which blocks the central visual axis, hampering the development of the growing eye and demanding earliest intervention, and the milder peripheral progressive cataract where surgery can wait. In order to understand this phenotypic dichotomy at the molecular level, we have studied the structural and aggregation features of representative mutations. Methods: Wild type and several representative mutant proteins were cloned, expressed and purified and their secondary and tertiary structural details, as well as structural stability, were compared in solution, using spectroscopy. Their tendencies to aggregate in vitro and in cellulo were also compared. In addition, we analyzed their structural differences by molecular modeling in silico. Results: Based on their properties, mutants are seen to fall into two classes. Mutants A36P, L45PL54P, R140X, and G165fs display lowered solubility and structural stability, expose several buried residues to the surface, aggregate in vitro and in cellulo, and disturb/distort the Greek key motif. And they are associated with nuclear cataract. In contrast, mutants P24T and R77S, associated with peripheral cataract, behave quite similar to the wild type molecule, and do not affect the Greek key topology. Conclusion: When a mutation distorts even one of the four Greek key motifs, the protein readily self-aggregates and precipitates, consistent with the phenotype of nuclear cataract, while mutations not affecting the motif display `native state aggregation', leading to peripheral cataract, thus offering a protein structural rationale for the cataract phenotypic dichotomy ``distort motif, lose central vision''.
