Sistema para a Predi??o do Crescimento da Corti?a
Almeida,Alice; Tomé,Margarida;
Silva Lusitana , 2008,
Abstract: cork growth modelling was based on two models: cork growth model for complete rings and a model for total cork thickness prediction. the cork growth model was developed using data from 189 cork samples taken at breast height. four biological growth functions were considered using their formulation as difference equations. the evaluation of the fitting and predictive ability of the models was based on model efficiency and on several statistics computed with the press residuals, complemented with graphical analysis to assess the regression assumptions. the model selected - lundqvist-a - can be used to predict cork thickness in complete rings at any year of the cork rotation. the model for the prediction of total cork thickness is used to predict total cork thickness from the thickness in complete rings.
Diagnosis of Tuberculosis in the Wild Boar (Sus scrofa): A Comparison of Methods Applicable to Hunter-Harvested Animals
Nuno Santos,Margarida Geraldes,Andreia Afonso,Virgílio Almeida,Margarida Correia-Neves
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0012663
Abstract: To obtain robust epidemiological information regarding tuberculosis (TB) in wildlife species, appropriate diagnostic methods need to be used. Wild boar (Sus scrofa) recently emerged as a major maintenance host for TB in some European countries. Nevertheless, no data is available to evaluate TB post-mortem diagnostic methods in hunter-harvested wild boar.
?N?o quero brincar?: a avalia??o psicológica e diagnóstica em saúde mental infantil
Almeida,Sara; Silva,Leonor Corrêa da; Fornelos,Margarida;
Análise Psicológica , 2003,
Abstract: the psychological evaluation might play an important role in the comprehension of the childhood working mental. by using psychometrics pre-defined and standardized instruments, it is possible achieve a better understanding of the cognitive potential and self organization, allowing the analyse of the behave, attitudes and reactions in the psychological evaluation setting. through the presentation of one clinical case about four years old boy, the authors pretend to show the contribution of the psychological evaluation for a better definition of the childhood psychopathology, in a multidisciplinary team.
Indicadores de morbimortalidade hospitalar de tuberculose no Município de S?o Paulo
Galesi, Vera Maria Neder;Almeida, Margarida Maria Mattos Brito de;
Revista Brasileira de Epidemiologia , 2007, DOI: 10.1590/S1415-790X2007000100006
Abstract: introduction: the treatment of tuberculosis is currently carried out in outpatient health services and hospitalization is only recommended for the more severe cases or for those facing social problems. in s?o paulo, however, a considerable number of tuberculosis patients are still hospitalized. objective: to study the socio-demographic and clinical-epidemiological characteristics of hospitalized tuberculosis patients in the city of s?o paulo in 2001. specific objective: to calculate tuberculosis morbimortality indicators for inpatients. methods: indicators of morbimortality of inpatients were calculated taking as sources, data from the s?o paulo state tuberculosis information system - (epitb) registration program, and the follow-up and analysis of reports and population data from deinfo/ sempla and fipe. results: a total of 2,473 tuberculosis patients were hospitalized in the city of s?o paulo in 2001. the hospitalization rate for these patients was 23.5 per 100,000 inhabitants, and the mortality rate found was 4.1 per 100,000 inhabitants with 485 deaths, yielding a fatality rate of 17.4%. discussion: the tb/hiv co-infection rate was of 32.7% among inpatients and 12.5% among those not hospitalized, showing that the aids epidemic has caused a considerable impact both in the magnitude and in the severity of the situation of hospitalized tuberculosis patients. the higher fatality rate (48.4%) is of disseminated / miliary tuberculosis, of which the majority occurs in hiv-positive patients. if, however, known hiv-positive cases are excluded, the fatality rate still remains high, i.e. 15%, showing that the severity of cases is not only due to co-infection. conclusions: taking all points into consideration, the indicators showed an alarming situation. recommendation: it is recommended that the epidemiological surveillance of municipalities establish flows and follow_up strategies for tuberculosis patients who have been hospitalized, mainly those in large urban centers, in

Revista Portuguesa de Pneumologia , 2006,
Abstract: the authors present the case of a child with severe idiopathic pulmonary hemosiderosis who after having begun treatment with hydroxychloroquine had a significant and lasting improvement. the efficacy of this therapeutic is pointed out. they also report the occurrence of clinical exacerbation, with hemoptysis, after receiving an influenza vaccine.
Peritonitis due to Rhizobium radiobacter
Raquel Marta,Catarina Damaso,José Esteves da Silva,Margarida Almeida
Einstein (S?o Paulo) , 2011,
Abstract: Rhizobium radiobacter (Agrobacterium radiobacter) is an aerobicGram-negative rod belonging to Agrobacterium genus, a groupof phytopathogenic bacteria present in the soil that has beenimplicated in human opportunistic infections. We report a clinicalcase of bacterial peritonitis in a 5-year-old child with chronic renaldisease in peritoneal dialysis, who had a history of direct soilcontact identified. The infection was treated with ceftazidime andpiperaciline+tazobactam without relapses or the need to remove theperitoneal dialysis catheter.
Interleukin-10: A Key Cytokine in Depression?
Susana Roque,Margarida Correia-Neves,Ana Raquel Mesquita,Joana Almeida Palha,Nuno Sousa
Cardiovascular Psychiatry and Neurology , 2009, DOI: 10.1155/2009/187894
Abstract: An increasing body of evidence implicates proinflammatory cytokines in psychiatric disorders, namely, in depression. Of notice, recent studies showed that anti-inflammatory cytokines, such as IL-10, also modulate depressive-like behavior. In this article, we propose that the anti-inflammatory cytokine IL-10 is a putative link between two of the most widely reported phenomenon observed in depressed patients: the disruption of the hypothalamic-pituitary-adrenal axis and the imbalanced production of cytokines. If so, IL-10 might represent a novel target for antidepressant therapy.
Influence of Spray-dried Hydroxyapatite-5-Fluorouracil Granules on Cell Lines Derived from Tissues of Mesenchymal Origin
Tim Scharnweber,Catarina Santos,Ralf-Peter Franke,Maria Margarida Almeida,Maria Elisabete V. Costa
Molecules , 2008, DOI: 10.3390/molecules13112729
Abstract: In our previous work we described the preparation and characterization of spray dried hydroxyapatite micro granules loaded with 5-fluorouracil (5-FU). These loaded particles are used as a model drug delivery system (DDS). In this study we examined the in vitro response of two cell lines derived from different tissues to 5-FU loaded granules (LG). Both cell lines, either L929 cells of a mouse fibroblast lineage or cells originating from a rat osteosarcoma (ROS 17/2.8) showed a dose dependent decrease in cell proliferation in response to 5-FU-, either dissolved in the culture medium or loaded onto particles. The response of the two cell lines to loaded and nonloaded particles was different. The effect of LG and of a corresponding concentration of free 5-FU was practically the same for the ROS 17/2.8 cells indicating that ROS 17/2.8 cells were not affected by the carrier material. In contrast, L929 cells showed a slight decrease in cell proliferation also in the presence of granules not loaded with 5-FU. This is thought to be attributed to the inhibition of mitogenesis by phosphocitrates, already demonstrated in fibroblasts. In summary, we found that the loaded 5-FU kept its effectivity after the spray drying process and that the response towards the granules varied with cell type. This is the first step towards a tissue specific DDS.
Hidropisia Fetal e Colestase Neonatal Caso Clínico
Afonso,Ariana; Alexandrino,Ana Margarida; Silva,Ermelinda Santos; Almeida,Alexandra; Santos,Gilberta Neves;
Nascer e Crescer - Revista do Hospital de Crian?as Maria Pia , 2010,
Abstract: there is a wide variety of disorders associated with non-immune hydrops fetalis and neonatal cholestasis. besides exhaustive investigation, in some cases it is not possible to identify an etiological factor. the approach to these entities should be supported by detailed anamnesis and a meticulous physical examination. additional testing must be oriented by clinical manifestations and the aim is prompt identi?cation of potential life-threatening diseases and treatable disorders. the authors present the diagnostic and therapeutic approaches in a premature newborn with hydrops fetalis, admitted in an intensive care neonatal unit soon after birth, who developed cholestasis from the 2nd day of life.
