Sair curado para a vida e para o bem: diagramas, linhas e dispersão de forças no complexus nosoespacial do Hospital de Caridade Juvino Barreto (1909-1927)

This work has as object of study the Hospital de Caridade Juvino Barreto, nosocomial institution located in the city of Natal (RN), between the Praia de Areia Preta and the Monte Petrópolis, focusing on the period from 1909, the year in which the new hospital building was constructed and opened, and 1927, the date of the transfer of administration of the public domain to the newly created Sociedade de Assistência Hospitalar (SAH). We study the conditions of possibility of the emergence of this hospital space in the urban environment of the capital of Rio Grande do Norte, seeking to understand the different tactics and strategies implemented by the historical subjects involved in the formation of this institution nosocomial. Starting from a corpus of documents consisting of medical memories (with Dr. Januário Cicco as privileged observer), information present in newspapers (the Republic and the Christmas Journa l), photo collection and extensive administrative and legal material (Speeches, Exhibitions, Reports, Laws and Resolutions), we analyzed in detail the medical geography of HCJB, relating the discourses of medicine and geography in choosing the spatial location of the hospital as we examine the architecture of the hospital, its inner spat iality, divisions, forms of space control, and, finally, we discuss the medical practices that took place within it, leading us in this regard, from the experiences of clinical hospital chief, Dr. Januário Cicco, especially the discussion on "ethics" in hospital work. The perception of HCJB as medical nosoespaciality always on the move, incorporated under taxonomic principles based on difference and dispersion forces, led us to articulate it theoretically from the conceptual-methodological arsenal of philosopher Michel Foucault, particularly his reflections of genealogical phase, focusing on the phenomenon of power, a position that allows us to enhance our space-hospital construction, invention, product of power relations, which give the unfinished aspect nosocômio, apparent, always at stake, perpetual non-modeling possibility has previously defined array, establishing it at the field of possible, of virtuality, of power: hospital that could have been and that it was not. Indeed, the investigation of various aspects/elements of hospital space Juvino Barreto revealed us new dimensions of hospital space, far more complex than the simple and the current idea of a place to shelter patients: plasticity and fluidity of space, which is not made to circumscribe the limits of empeiria, engraving up to strength relations fought between different subject; its Constitution as a transitional space, Heterotopic, doing live inside modern elements with premoderns (professional doctors working with religious thought, skeptical of positivist medicine living with the religious faith of the nuns of Santana); the impossibility of thinking hospital space of HCJB while homogeneous unit, static, transistoric, making the spatiality, without considering the profound differences, fractures and dislocations that animated his own existence, multiplying their expressions of identity

Predation of Platyrrhinus lineatus (E. Geoffroy, 1810) (Chiroptera: Phyllostomidae) by Cyanocorax chrysops (Vieillot, 1818) (Passeriformes: Corvidae).

The predation on vertebrates by birds, including bats, is very common in some families (Accipitridae, Falconidae, Tytonidae, Strigidae), constituting their main diet. For other families (except those that feed strictly on fish), it is occasional and sometimes a matter of opportunity. Here we recorded the predation on a bat (Platyrrhinus lineatus) by the neotropical bird plush-crested jay (Cyanocorax chrysops). on July 26, 2009, around 11:00 am, we recorded an individual of C. chrysops taking part of a P. lineatus on its beak. This record occurred on Jacarezinho Farm (Valparaiso [long dash] SP). The prey species identification was done by visual observation, considering the bat size and its external morphology, especially by the presence of the white dorsal bright stripe. Probably, Platyrrhinus lineatus behavior, which involves living together or in couples on tree canopies, made the capture by the plush-crested jay easier. This is a new record for the diet of C. chrysops and highlights the necessity of additional studies related to birds diet in the Neotropics, even the more conspicuous ones.

End-systolic pressure-diameter relation of the left ventricle during transient and sustained elevations of blood pressure

OBJECTIVE: To assess the effect of transient and sustained variations in cardiac load on the values of the end-systolic pressure-diameter relation (ESPDR) of the left ventricle. METHODS: We studied 13 dogs under general anesthesia and autonomic blockade. Variations of cardiac loads were done by elevation of blood pressure by mechanical constriction of the aorta. Two protocols were used in each animal: gradual peaking and decreasing pressure variation, the transient arterial hypertension protocol (TAH), and a quick and 10 min sustained elevation, the sustained arterial hypertension protocol(SAH). Then, we compared the ESDR in these two situations. RESULTS: Acute elevation of arterial pressure, being it transitory or sustained, did not alter the heart frequency and increased similarly the preload and after load. However, they acted differently in end systolic pressure-diameter relation. It was greater in the SAH than TAH protocol, 21.0±7.3mmHg/mm vs. 9.2±1.2mmHg/mm (p<0.05). CONCLUSION: The left ventricular ESPDR values determined during sustained pressure elevations were higher than those found during transient pressure elevations. The time-dependent activation of myocardial contractility associated with the Frank-Starling mechanism is the major factor in inotropic stimulation during sustained elevations of blood pressure, determining an increase in the ESPDR values.

Influência da idade no comportamento da pressão intraocular em uma população da região Sul-brasileira

OBJETIVO: Verificar influência da idade no comportamento da pressão intraocular (PIO) em população acima de 40 anos. MÉTODOS: Neste estudo observacional transversal realizado no município de Piraquara - PR, a PIO foi aferida através da tonometria de Goldmann. Todos os indivíduos foram submetidos a exame de triagem, sendo os suspeitos de glaucoma ou hipertensão ocular encaminhados ao atendimento de retorno para realização de exame oftalmológico completo. Para fins de análise estatística, os pacientes foram divididos em grupos etários (40-49; 50-59; 60-69 e acima de 70 anos). Posteriormente todos os pacientes portadores de glaucoma ou suspeita, hipertensão arterial sistêmica (HAS) ou Diabetes mellitus (DM) foram excluídos. RESULTADOS: Avaliaram-se 3360 indivíduos com média de idade de 54,04 ± 10,52 anos, sendo 59,79% do sexo feminino. Não se observou diferença estatisticamente significativa entre a média da PIO nos diferentes grupos etários (p=0,19; teste ANOVA). da mesma forma, não foi observada correlação significativa entre a PIO e a idade (p = 0,11; correlação linear de Pearson). Após exclusão dos indivíduos portadores de HAS (1671), DM (n=360), glaucoma ou suspeita de glaucoma (n=161) não se observou diferença estatisticamente significativa entre a média da PIO e a idade (p=0,17; teste ANOVA). No entanto, uma fraca correlação negativa, porém significativa, foi encontrada entre PIO e idade (p=0,03; R=-0,055, correlação linear Pearson). CONCLUSÃO: Na presente amostra, não foi observada influência significativa da idade na PIO, entretanto, após a exclusão de indivíduos com glaucoma, HAS e DM, observou-se uma fraca correlação linear negativa e significativa entre as duas variáveis.

Assessing the uncertainties of model estimates of primary productivity in the tropical Pacific Ocean

Depth-integrated primary productivity (PP) estimates obtained from satellite ocean color-based models (SatPPMs) and those generated from biogeochemical ocean general circulation models (BCGCMs) represent a key resource for biogeochemical and ecological studies at global as well as regional scales. Calibration and validation of these PP models are not straightforward, however, and comparative studies show large differences between model estimates. The goal of this paper is to compare PP estimates obtained from 30 different models (21 SatPPMs and 9 BOGCMs) to a tropical Pacific PP database consisting of similar to 1000 C-14 measurements spanning more than a decade (1983-1996). Primary findings include: skill varied significantly between models, but performance was not a function of model complexity or type (i.e. SatPPM vs. BOGCM); nearly all models underestimated the observed variance of PR specifically yielding too few low PP (< 0.2 g Cm-2 d(-1)) values; more than half of the total root-mean-squared model-data differences associated with the satellite-based PP models might be accounted for by uncertainties in the input variables and/or the PP data; and the tropical Pacific database captures a broad scale shift from low biomassnormalized productivity in the 1980s to higher biomass-normalized productivity in the 1990s, which was not successfully captured by any of the models. This latter result suggests that interdecadal and global changes will be a significant challenge for both SatPPMs and BOGCMs. Finally, average root-mean-squared differences between in situ PP data on the equator at 140 degrees W and PP estimates from the satellite-based productivity models were 58% lower than analogous values computed in a previous PP model comparison 6 years ago. The success of these types of comparison exercises is illustrated by the continual modification and improvement of the participating models and the resulting increase in model skill.

Influência da elevaçáo transitória e da elevaçáo sustentada da pressáo arterial sobre a primeira derivada temporal da pressáo ventricular.

PURPOSE--To analyze the influence of transient and sustained elevations of arterial pressure (AP) on the rate of rise of the left ventricular pressure (dp/dt). METHODS--Thirteen anesthetized, thoracotomized and mechanically ventilated dogs, submitted to pharmacological autonomic block (oxprenolol-3 mg/kg plus atropine-0.5 mg/kg). The AP elevation was obtained by mechanical constriction of the descending thoracic aorta. Two protocols were applied to all animals: Transient Arterial Hypertension (TAH) and Sustained Arterial Hypertension (SAH) and the following variables were evaluated: heart rate (HR), systolic (LVSP) and end diastolic (LVEDP) left ventricular pressure and dp/dt. In TAH the variables were analyzed in the basal condition (To) and at the maximal value of AP attained during the transient pressure elevation (TM). In the protocol SAH the variables were evaluated in the conditions: Control (Ho), hypertension 1 (H1) and hypertension 2 (H2). RESULTS--Considering all conditions, there were no significant differences among the values of HR. In the protocol TAH, the LVSP varied from 133 +/- 22 mmHg to 180 +/- 27 mmHg, whereas in SAH the values of LVSP were as follow: HO = 129 +/- 25 mmHg; H1 = 152 = 23 mmHg; H2 = 182 +/- 24 mmHg. LVEDP changed in both protocols: To = 7 +/- 2 mmHg; TM = 13 +/- 2 mmHg (p < 0.05); Ho = 7 +/- 2 mmHg; H1 = 10 +/- 2 mmHg; H2 = 14 +/- 3 mmHg (p < 0.05). During TAH there was no difference between the values of dp/dt (To = 3.303 +/- 598 mmHg/s; TM = 3.350 +/- 653 mmHg/s; p > 0.05), however, there were increases of the dp/dt during SAH (Ho = 3.233 +/- 576 mmHg/s; H1 = 3.831 +/- 667 mmHg/s; H1 = 4.594 +/- 833 mmHg/2; p < 0.05). CONCLUSION--The values of dp/dt are not influenced by transient elevation of AP. Sustained increase of AP activates cardiac adjustments, which results in elevation of dp/dt, by stimulation of contractile state. Probably, the inotropic intervention mechanism is the length dependent activation due to the Frank-Starling mechanism.

The genetics of New World monkey visual pigments

To have color vision, having at least two cone photopigment types with different spectral sensitivities present in distinct photoreceptors is necessary together with the neural circuitry necessary to extract color information. Visual pigments are highly conserved molecules, but differences can be found among vertebrate groups. Primates have a variety of cone photopigments (i.e., opsins) that are expressed by polymorphic genes. This article examines the diversity of cone photopigments in New World monkeys and their behavioral relevance.
