Predictors of red blood cell transfusion after cardiac surgery: a prospective cohort study

Abstract OBJECTIVE To identify predictors of red blood cell transfusion (RBCT) after cardiac surgery. METHOD A prospective cohort study performed with 323 adults after cardiac surgery, from April to December of 2013. A data collection instrument was constructed by the researchers containing factors associated with excessive bleeding after cardiac surgery, as found in the literature, for investigation in the immediate postoperative period. The relationship between risk factors and the outcome was assessed by univariate analysis and logistic regression. RESULTS The factors associated with RBCT in the immediate postoperative period included lower height and weight, decreased platelet count, lower hemoglobin level, higher prevalence of platelet count <150x10 3/mm3, lower volume of protamine, longer duration of anesthesia, higher prevalence of intraoperative RBCT, lower body temperature, higher heart rate and higher positive end-expiratory pressure. The independent predictor was weight <66.5Kg. CONCLUSION Factors associated with RBCT in the immediate postoperative period of cardiac surgery were found. The independent predictor was weight.

Deposits of transforming growth factor-beta-induced protein in granular corneal dystrophy type II after LASIK.

PURPOSE: To analyze components of the deposits in the corneal flap interface of granular corneal dystrophy type II (GCD II) patients after laser in situ keratomileusis (LASIK). METHODS: Four corneal GCD II specimens displaying disease exacerbation after LASIK were analyzed. Three of these specimens included the recipient corneal button after penetrating keratoplasty or deep lamellar keratoplasty for advanced GCD II after LASIK. The fourth specimen, a similar case of GCD II after LASIK, included the amputated corneal flap. Specimens were processed for histopathologic and immunohistochemical analyses. RESULTS: Corneal stromal deposits in the LASIK flaps of all specimens were stained with 3 anti-transforming growth factor-beta-induced protein (TGFBIp) antibodies. The deposits displayed bright red color staining with Masson trichrome; however, negative staining was seen with Congo red, suggesting that hyaline is the main component localizing to the TGFBIp deposits rather than amyloid. CONCLUSIONS: Amorphous granular material deposited along the interface of the LASIK flap in GCD II corneas is composed mainly of hyaline deposits.

Red tape and delayed entry

Does cutting red tape foster entrepreneurship in industries with the potential to expand? We address this question by combining the time needed to comply with government entry procedures in 45 countries with industry-level data on employment growth and growth in the number of establishments during the 1980s. Our main empirical finding is that countries where it takes less time to register new businesses have seen more entry in industries that experienced expansionary global demand and technology shifts. Our estimates take into account that proxying global industry shifts using data from only one country or group of countries with similar entry regulations will in general yield biased results.

Antibody-indocyanin conjugates for immunophotodetection of human squamous cell carcinoma in nude mice.

We have recently shown that immunophotodetection of human colon carcinomas in nude mice and in patients is possible by using anti-carcinoembryonic antigen monoclonal antibodies (MAb) coupled to fluorescein. The most common clinical application of photodiagnosis has been for the detection of squamous cell carcinomas (SCC) in the upper respiratory tract, but the free dyes used have a poor tumor selectivity. We selected the known MAb E48 directed against SCC and coupled it to a fluorescent dye: indopentamethinecyanin (indocyanin). This dye has an advantage over fluorescein in that it emits a more penetrating fluorescent red signal at 667 nm after excitation with a laser ray of 640 nm. In vitro, an conjugate with an indocyanin:MAb molar ratio of 2, and an additional trace labeling with 125I, showed more than 80% of binding to cells from the SCC line A431. In vivo, when injected i.v. into nude mice bearing xenografts of the same carcinoma line, the MAb E48-(indocyanin)2 conjugate was almost as efficient as the unconjugated MAb E48 in terms of specific tumor localization: 15% of the injected dose per g of tumor at 24 h after injection and a tumor:overall normal tissue ratio of 6-8. There was no selective tumor localization of an irrelevant IgG1-(indocyanin)2 conjugate. Immunophotodetection of the s.c. SCC xenografts on mice given injections of 100 micrograms of MAb E48-(indocyanin), conjugate (representing 1 microgram of indocyanin) was performed at 24 h. Upon laser irradiation, clearly detectable red fluorescence from the indocyanin-MAb conjugate was observed specifically in the SCC xenografts across the mouse skin. In comparison, injection of 100 micrograms of a MAb E48 coupled to 2 micrograms of fluorescein gave a specific green fluorescence signal in the tumor xenografts, which was detectable, however, only after removing the mouse skin. Injection i.v. of a 15 times higher amount of free indocyanin (15 micrograms) gave a diffuse red fluorescence signal all over the mouse body with no definite increase in intensity in the tumor, indicating a lack of tumor selectivity of the free dye. The results demonstrate the possibility of broadening and improving the efficiency of tumor immunophotodiagnosis by coupling to a MAb directed against SCC, a fluorescent dye absorbing and emitting at higher wavelength than fluorescein, and thus having deeper tissue penetration and lower tissue autofluorescence. Such a demonstration opens the way to a new form of clinical immunophotodiagnosis and possibly to the development of a more specific approach to phototherapy of early bronchial carcinomas.

Thirteen polymorphic microsatellite markers for the European green toad Bufo viridis viridis, a declining amphibian species.

We report 13 new polymorphic microsatellite markers for the European green toad Bufo viridis viridis (B. viridis subgroup), a declining amphibian from Central, Southeastern and Eastern Europe. Diversity at these loci estimated for 19 individuals ranged from two to ten alleles. Most of these primers also cross-amplify in related West-Mediterranean green toad species (Bufo balearicus, B. siculus and B. boulengeri). These microsatellites will be useful for conservation genetics of threatened Bufo viridis viridis populations and evolutionary studies of green toad taxa in secondary contact to examine hybridization.

Presentan los resultados obtenidos del estudio de selectividad en merluza peruana (Merluccius gayi peruanus) con una red de arrastre de fondo, en el área pesquera de Paita (03° a 05° S), basado en el método de copo cubierto (POPE et al. 1975) con diferentes tamaños de malla (poliamida PA-nylon), 90, 105, 110 y 120 mm. Se observó que la diferencia entre el factor de selección calculado por los distintos análisis para la mallas 105 (106) mm y 110 (114) mm no fue significativa, razón por la cual fueron seleccionadas para aplicar los modelos matemáticos adicionales de GULLAND 1970 y BARANOV 1960, determinándose el tamaño óptimo de malla de 110 mm. El factor de selección (FS) para la malla de 90(90,8)mm fue igual a 3,41; para la malla de 105 (106) mm, igual a 3,03; para la malla de 110 (114) mm fue igual a 2,99; para la malla de 120 (122) mm, fue igual a 2,84.

Avaliação dos Fatores que Afetaram a Produtividade das Galinhas Poedeiras (RHODE ISLAND RED) Durante as Primeiras 52ª Semana, no Aviário do INIDA

Cabo Verde é um país com algum potencial no sector do agronegócios, representando cerca de trinta porcento (30%) dos rendimentos da população rural. Muito tem sido feito para melhorar este sector, contudo, devido à falta de espaço e de pastos, vem buscando alternativas mais viáveis para a criação de animais, que ocupam menos espaço e que produzam mais por m2. O número de aves domésticas em Cabo Verde foi estimada em 431.194, desses noventa e quatro porcento (94%) representava a criação de galinhas. A ilha de Santiago foi a maior produtora com quarenta e sete porcento (47%) dos efetivos, em seguida a ilha de São Vicente com vinte porcento (20%). Temperatura, instalações, nutrição e o manejo são variáveis importantes para o bem-estar animal e devem ser encarados em sinergia. Quando não estão de acordo com as necessidades mínimas exigidas levam as aves para fora da zona de conforto. A temperatura ideal para a criação de galinhas poedeiras na fase de produção deve rondar os 17 °C e os 28°C, e nos primeiros dias de vida de 33°C a 35°C. Em Cabo Verde ainda não existe a preocupação em proporcionar condições ideias para as aves de criação, visto que ainda é feita, na sua grande maioria, de forma tradicional e com pouca ou nenhuma tecnologia que vise um melhor desempenho produtivo das aves. Este trabalho teve como objetivos específicos: • Monitorizar o consumo de ração por aves; • Registar a postura diária e determinar a produção/produtividade; • Analisar os factores que afectam a produção/produtividade de ovos no aviário do INIDA;

The adverse effects of environmental policy in green markets

We model green markets in which purchasers, either firms orconsumers, have higher willingness-to-pay for lesspolluting goods. The effectiveness of pollution reductionpolicies is examined in a duopoly setting. We show thatduopolists' strategic behaviour may increase pollutionlevels. Maximum emission standards, commonly used in greenmarkets, improve the environmental features of products.Nonetheless, overall pollution levels will rise becausegovernment regulation also affects market shares and bootsfirms' sales. Consequently, social welfare may be reduced.We also explore the effects of technological subsidies andproduct charges, including differentiation of charges.

REST/NRSF governs the expression of dense-core vesicle gliosecretion in astrocytes.

Astrocytes are the brain nonnerve cells that are competent for gliosecretion, i.e., for expression and regulated exocytosis of clear and dense-core vesicles (DCVs). We investigated whether expression of astrocyte DCVs is governed by RE-1-silencing transcription factor (REST)/neuron-restrictive silencer factor (NRSF), the transcription repressor that orchestrates nerve cell differentiation. Rat astrocyte cultures exhibited high levels of REST and expressed neither DCVs nor their markers (granins, peptides, and membrane proteins). Transfection of a dominant-negative construct of REST induced the appearance of DCVs filled with secretogranin 2 and neuropeptide Y (NPY) and distinct from other organelles. Total internal reflection fluorescence analysis revealed NPY-monomeric red fluorescent protein-labeled DCVs to undergo Ca(2+)-dependent exocytosis, which was largely prevented by botulinum toxin B. In the I-II layers of the human temporal brain cortex, all neurons and microglia exhibited the expected inappreciable and high levels of REST, respectively. In contrast, astrocyte REST was variable, going from inappreciable to high, and accompanied by a variable expression of DCVs. In conclusion, astrocyte DCV expression and gliosecretion are governed by REST. The variable in situ REST levels may contribute to the well-known structural/functional heterogeneity of astrocytes.
