Modelos de gestão e o SUS

O recente documento do Ministério do Planejamento sobre Fundações Públicas (2005) e a crise da área hospitalar colocaram novamente na agenda do SUS a questão dos modelos de gestão pública. O objetivo deste artigo é situar no contexto das reformas de estado pensadas na década de 90 para o Brasil, as propostas de mudança dos modelos de gestão da administração pública, com foco no processo de implementação do SUS. Essa abordagem trata em primeiro lugar da personalidade jurídica das organizações de saúde na esfera estatal, conceituando o público a partir de seus objetivos; em segundo, discute o contexto as reformas de estado e as mudanças propostas para a administração pública. Os autores entendem que critérios e parâmetros para avaliação institucional devem contemplar quatro aspectos: subordinação à política de saúde; legalidade; eficiência gerencial e capacidade de controle. A partir do quadro de referencia geral elaborou-se uma análise comparativa em relação à proposta das fundações públicas de direito privado. Na análise comparativa das características desse tipo de entidade proposta para gestão hospitalar, observam-se semelhanças com a proposta de Organizações Sociais. Fundação Estatal e Contrato de Gestão podem ser vistos como modelos que possibilitam modernizar o Estado, além de re-introduzirem o tema da reforma hospitalar na agenda governamental brasileira

Visual Feedforward Control in Human Locomotion During Avoidance of Obstacles that Change Size

The purpose of the current study was to understand how visual information about an ongoing change in obstacle size is used during obstacle avoidance for both lead and trail limbs. Participants were required to walk in a dark room and to step over an obstacle edged with a special tape visible in the dark. The obstacle's dimensions were manipulated one step before obstacle clearance by increasing or decreasing its size. Two increasing and two decreasing obstacle conditions were combined with seven control static conditions. Results showed that information about the obstacle's size was acquired and used to modulate trail limb trajectory, but had no effect on lead limb trajectory. The adaptive step was influenced by the time available to acquire and process visual information. In conclusion, visual information about obstacle size acquired during lead limb crossing was used in a feedforward manner to modulate trail limb trajectory.

A gestão do conhecimento na educação ambiental

Information and knowledge are resources of environmental education (EE) that can be performed through knowledge management (KM). The aim of this paper is to propose measures of knowledge creation (KC) to improve performance of EE. This study is based on the research literature without empirical findings; therefore, the results are limited by the methodological resources of the theoretical essay. However, this limitation is the greatest motivation for future research which could investigate the proximity of EE with KM and KC in empirical investigations. Some suggestions for developing the requirements of KC programs to EE are presented as the results: possibility of the SECI process to better perform various aspects of environmental education such as social learning, interaction activities, dialogue, experience exchanging, information and knowledge, and of different ideas and ways of acting, done by EE and, finally, the possibility of Ba to develop a proper space for creation of new environmental knowledge. This article contains academic contributions to KM by providing greater discussion and understanding of KC; to EE when it allows a different view based on the work of information and knowledge about the processes of teaching, when contributing to social programs for EE, improving their practices and, consequently, contributing to an environmentally sustainable economic development.

Aportes da gestão da informação para a criação de conhecimento em equipes de inovação

Information and knowledge have been cited for two decades as competitive advantage tools. Recently, the use of them is discussed in promotion of the innovation. The premise indicates that human interaction, information sharing and knowledge creation are vital for the success of organizations that need to learn and innovate all the time. This paper has the intention to point contributions from a dynamic environment of acquisition, dissemination and the use of information to the subsequent knowledge creation and the formation of innovation teams.

Gestão do Conhecimento: a produção científica em períodos brasileiros entre 1997 e 2006

This study analyzes how the subject ""Knowledge Management"" (KM) has been published by authors of the Information Science (IS) and Administration (ADM). The research identifies the most productive periodicals, the most prolific institutions and authors in each area, as well as the results obtained. This is a study that presents the mapping of the Brazilian scientific production on KM, in national periodicals level A from CAPES, in the IS and ADM areas. The study is divided into three periods: 1997-2006, 1997-2001 and 2002-2006. The theoretical foundation is based on Nonaka and Takeuchi, Davenport and Prusak, Davenport and Cronin. Seventy-six articles are analyzed, forty in the IS area and thirty-six in the ADM area. The results indicate that the IS has published much more on the subject KM than the ADM. Although the chart presented is not exhaustive, it represents an important sample of the Brazilian scientific production on KM, from 1997-2006.

Altazor, de Vicente Huidobro: o gesto político numa das epopeias de XX

This article aims at presenting a reading of Vicente Huidobro's poem Altazor (1931,) assuming the epic genre postulations and the conditions of its development in the first half of the twentieth century. Important works were produced in that period, setting in motion a deployment of the epic genre as refashioned by the avant-garde movements and contesting the metaphysical formulations that had considered it impossible as a discursive space in modern times. Altazor is situated in this movement as a self-conscience of issues of language and its objective capacities. The work deals with the possible modes of enunciation of a great poet, Altazor, who lacks his former serenity of old and looks for a language able to transcend his mother tongue, because he does not accept its origin. His political revolution is performed on language, the artifice through which history is told.

Sociedade e gestão do risco: o aquífero Guarani em Ribeirão Preto-SP, Brasil

Contemporary society creates risks of all kinds, changing the meaning of this term. Although it may be associated with natural hazards, it gradually assumes a stronger relation with human actions, especially due to the use of technology. The use of land for agricultural and urban activities creates the possibility of contamination in the recharge area of the Guarani aquifer in the municipality of Ribeirao Preto, state of Sao Paulo, Brazil. This city is one of the most important in the state with high economic development. Besides this, it is located in the recharge area of the main reservoir of underground water of South Cone. This paper aims to discuss the management of groundwater use in Ribeirao Preto and reflects the risk that contamination and overexploitation might cause to the main city's water supply.

Monocular vision and increased distance reducing the effects of visual manipulation on body sway

The goal of this study was to examine the coupling between visual information and body sway with binocular and monocular vision at two distances from the front wall of a moving room. Ten participants stood as still as possible inside of a moving room facing the front wall in conditions that combined room movement with monocular/binocular vision and distance from the front wall (75 and 150cm). Visual information effect on body sway decreased with monocular vision and with increased distance from the front wall. In addition, the combination of monocular vision with the farther distance resulted in the smallest body sway response to the driving stimulus provided by the moving room. These results suggest that binocularvision near the front wall provides visual information of a better quality than the monocular vision far from the front wall. We discuss the results with respect to two modes of visual detection of body sway: ocular and extraocular. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

The look of royalty: visual and odour signals of reproductive status in a paper wasp

Reproductive conflicts within animal societies occur when all females can potentially reproduce. In social insects, these conflicts are regulated largely by behaviour and chemical signalling. There is evidence that presence of signals, which provide direct information about the quality of the reproductive females would increase the fitness of all parties. In this study, we present an association between visual and chemical signals in the paper wasp Polistes satan. Our results showed that in nest-founding phase colonies, variation of visual signals is linked to relative fertility, while chemical signals are related to dominance status. In addition, experiments revealed that higher hierarchical positions were occupied by subordinates with distinct proportions of cuticular hydrocarbons and distinct visual marks. Therefore, these wasps present cues that convey reliable information of their reproductive status.

Three-monthly intravitreal bevacizumab injections for neovascular age-related macular degeneration: short-term visual acuity results

PURPOSE. To evaluate the change in vision after 3 monthly consecutive intravitreal injections of 1.25 mg of bevacizumab for neovascular age-related macular degeneration (AMD). METHODS. A retrospective analysis of 35 eyes was performed. Visual acuity (VA) at initial visit and at each follow-up visit was compared. The injection of bevacizumab was performed at 30-day intervals and patients were observed for 5 months after the last injection. RESULTS. Of the 35 eyes, 9 had received previous treatment with photodynamic therapy with or without 4 mg of intravitreal triamcinolone. VA was measured in Snellen table and transformed into logMAR for statistical purposes. Mean age was 76.66 years (range, 49-90 years). There were 24(69%) women and 11(31%) men. Mean VA at the initial visit was 0.92 +/- 0.50. At month 1, mean VA was 0.84 +/- 0.51 and at month 2 was 0.74 +/- 0.51. At month 3, mean VA remained 0.74 +/- 0.49. Six and 8 months after the initial visit, VA was 0.79 +/- 0.49 and 0.77 +/- 0.50, respectively. The improvement in VA was statistically significant at month 2 and at the end of the follow-up (8 months) compared with the baseline VA. CONCLUSIONS. Three consecutive monthly injections of intravitreal bevacizumab to treat neovascular AMD is effective in improving VA in the short term. Longer prospective studies should be performed to confirm VA stability after the third injection. (Eur J Ophthalmol 2010; 20: 740-4)

Correlation between macular and retinal nerve fibre layer Fourier-domain OCT measurements and visual field loss in chiasmal compression

Purpose The aim of this study was to test the correlation between Fourier-domain (FD) optical coherence tomography (OCT) macular and retinal nerve fibre layer (RNFL) thickness and visual field (VF) loss on standard automated perimetry (SAP) in chiasmal compression. Methods A total of 35 eyes with permanent temporal VF defects and 35 controls underwent SAP and FD-OCT (3D OCT-1000; Topcon Corp.) examinations. Macular thickness measurements were averaged for the central area and for each quadrant and half of that area, whereas RNFL thickness was determined for six sectors around the optic disc. VF loss was estimated in six sectors of the VF and in the central 16 test points in the VF. The correlation between VF loss and OCT measurements was tested with Spearman`s correlation coefficients and with linear regression analysis. Results Macular and RNFL thickness parameters correlated strongly with SAP VF loss. Correlations were generally stronger between VF loss and quadrantic or hemianopic macular thickness than with sectoral RNFL thickness. For the macular parameters, we observed the strongest correlation between macular thickness in the inferonasal quadrant and VF loss in the superior temporal central quadrant (rho=0.78; P<0.001) whereas for the RNFL parameters the strongest correlation was observed between the superonasal optic disc sector and the central temporal VF defect (rho=0.60; P<0.001).

Abnormal Visual Activation in Parkinson`s Disease Patients

Among nonmotor symptoms observed in Parkinson`s disease (PD) dysfunction in the visual system, including hallucinations, has a significant impact in their quality of life. To further explore the visual system in PD patients we designed two fMRI experiments comparing 18 healthy volunteers with 16 PD patients without visual complaints in two visual fMRI paradigms: the flickering checkerboard task and a facial perception paradigm. PD patients displayed a decreased activity in the primary visual cortex (Broadmann area 17) bilaterally as compared to healthy volunteers during flickering checkerboard task and increased activity in fusiform gyms (Broadmann area 37) during facial perception paradigm. Our findings confirm the notion that PD patients show significant changes in the visual cortex system even before the visual symptoms are clinically evident. Further studies are necessary to evaluate the contribution of these abnormalities to the development visual symptoms in PD. (C) 2010 Movement Disorder Society

Long-Term Astroglial Reaction and Neuronal Plasticity in the Subcortical Visual Pathways After a Complete Ablation of Telencephalon in Pigeons (Columba livia)

This paper analyzes the astroglial and neuronal responses in subtelencephalic structures, following a bilateral ablation of the telencephalon in the Columba livia pigeons. Control birds received a sham operation. Four months later the birds were sacrificed and their brains processed for glial fribillary acid protein (GFAP) and neurofilament immunohistochemistry, markers for astrocytes and neurons, respectively. Computer-assisted image analysis was employed for quantification of the immunoreactive labeling in the nucleus rotundus (N.Rt) and the optic tectum (OT) of the birds. An increased number of GFAP immunoreactive astrocytes were found in several subregions of the N.Rt (p .001), as well as in layers 1, 2cd, 3, and 6 of the OT (p .001) of the lesioned animals. Neurofilament immunoreactivity decreased massively in the entire N.Rt of the lesioned birds; however, remaining neurons with healthy aspect showing large cytoplasm and ramified branches were detected mainly in the periphery of the nucleus. In view of the recently described paracrine neurotrophic properties of the activated astrocytes, the data of the present study may suggest a long-lasting neuroglial interaction in regions of the lesioned bird brain far from injury. Such events may trigger neuronal plasticity in remaining brain structures that may lead spontaneous behavior recovery as the one promoted here even after a massive injury.

Risk Factors for Visual Field Progression in Treated Glaucoma

Objective: To determine intraocular pressure (IOP)-dependent and IOP-independent variables associated with visual field (VF) progression in treated glaucoma. Design: Retrospective cohort of the Glaucoma Progression Study. Methods: Consecutive, treated glaucoma patients with repeatable VF loss who had 8 or more VF examinations of either eye, using the Swedish Interactive Threshold Algorithm (24-2 SITA-Standard, Humphrey Field Analyzer II; Carl Zeiss Meditec, Inc, Dublin, California), during the period between January 1999 and September 2009 were included. Visual field progression was evaluated using automated pointwise linear regression. Evaluated data included age, sex, race, central corneal thickness, baseline VF mean deviation, mean follow-up IOP, peak IOP, IOP fluctuation, a detected disc hemorrhage, and presence of beta-zone parapapillary atrophy. Results: We selected 587 eyes of 587 patients (mean [SD] age, 64.9 [13.0] years). The mean (SD) number of VFs was 11.1 (3.0), spanning a mean (SD) of 6.4 (1.7) years. In the univariable model, older age (odds ratio [OR], 1.19 per decade; P = .01), baseline diagnosis of exfoliation syndrome (OR, 1.79; P = .01), decreased central corneal thickness (OR, 1.38 per 40 mu m thinner; P < .01), a detected disc hemorrhage (OR, 2.31; P < .01), presence of beta-zone parapapillary atrophy (OR, 2.17; P < .01), and all IOP parameters (mean follow-up, peak, and fluctuation; P < .01) were associated with increased risk of VF progression. In the multivariable model, peak IOP (OR, 1.13; P < .01), thinner central corneal thickness (OR, 1.45 per 40 mu m thinner; P < .01), a detected disc hemorrhage (OR, 2.59; P < .01), and presence of beta-zone parapapillary atrophy (OR, 2.38; P < .01) were associated with VF progression. Conclusions: IOP-dependent and IOP-independent risk factors affect disease progression in treated glaucoma. Peak IOP is a better predictor of progression than is IOP mean or fluctuation.

The Relationship between Intraocular Pressure Reduction and Rates of Progressive Visual Field Loss in Eyes with Optic Disc Hemorrhage

Purpose: To evaluate rates of visual field progression in eyes with optic disc hemorrhages and the effect of intraocular pressure (IOP) reduction on these rates. Design: Observational cohort study. Participants: The study included 510 eyes of 348 patients with glaucoma who were recruited from the Diagnostic Innovations in Glaucoma Study (DIGS) and followed for an average of 8.2 years. Methods: Eyes were followed annually with clinical examination, standard automated perimetry visual fields, and optic disc stereophotographs. The presence of optic disc hemorrhages was determined on the basis of masked evaluation of optic disc stereophotographs. Evaluation of rates of visual field change during follow-up was performed using the visual field index (VFI). Main Outcome Measures: The evaluation of the effect of optic disc hemorrhages on rates of visual field progression was performed using random coefficient models. Estimates of rates of change for individual eyes were obtained by best linear unbiased prediction (BLUP). Results: During follow-up, 97 (19%) of the eyes had at least 1 episode of disc hemorrhage. The overall rate of VFI change in eyes with hemorrhages was significantly faster than in eyes without hemorrhages (-0.88%/year vs. -0.38%/year, respectively, P < 0.001). The difference in rates of visual field loss pre- and post-hemorrhage was significantly related to the reduction of IOP in the post-hemorrhage period compared with the pre-hemorrhage period (r = -0.61; P < 0.001). Each 1 mmHg of IOP reduction was associated with a difference of 0.31%/year in the rate of VFI change. Conclusions: There was a beneficial effect of treatment in slowing rates of progressive visual field loss in eyes with optic disc hemorrhage. Further research should elucidate the reasons why some patients with hemorrhages respond well to IOP reduction and others seem to continue to progress despite a significant reduction in IOP levels.
