Abstract: considering that the indiscriminate use of wide spectrum antibiotics has favour the appearance of bacterial resistance to multiple drugs, a quasi-experiemental intervention study was performed between january 2002 and january 2006, in the neonatal intensive care unit (nicu) of the hospital militar central in bogotá (hmc), in which the use of cephalosporins of 3th generation was restricted and changed for antibiotics non associated with the induction of beta-lactamases of extended spectrum (esbls), by the use of piperacillin-tazobactam and cefepime. a comparison was done before and after the restriction policy was applied in nosocomial infections produced by gram-negative bacteria. it was found that 24, 5% out of 2880 patients were diagnose with infections and among them, 30,7% were nosocomial infection. 49% of isolated germs were gram-negative bacteria from which 51% of klebsiella pneumoniae, 28% of escherichia coli, 14% of acinetobacter baumannii and 7% of serratia isolates produced esbls. in 70% of the esbls cases, cephalosporins of 3er generation were used. after restriction of cephalosporins of 3 th generation an important decreased in the number of beta-lactamic resistance isolates were observed (from 20% during the first period to less than 4 % during the second), which means that the risk of esbls production decreased five times, with a ratio of prevalence of 4,91 (ic 95%: 1,14-21,09) and a p value of 0,031 with respect to the previous period. it can be conclude that the adoption of a restriction policy in the use of antibiotics had a significant reductor effect on the incidence of esbls in nicu of our hospital, which implies a reduction of costs as the use of carbapenems was also reduced.

Abstract: Teniendo en cuenta que el uso indiscriminado de antibióticos de amplio espectro ha favorecido la aparición de resistencia bacteriana a múltiples drogas, se realizó un estudio de intervención cuasiexperimental entre enero de 2002 y enero de 2006 en la unidad de cuidados intensivos neonatal (UCIN) del Hospital Militar Central de Bogotá (HMC), en el que se restringió el uso de cefalosporinas de 3a generación cambiándolas por antibióticos no asociados con inducción de beta-lactamasas de espectro extendido (BLEEs), utilizando piperazilina-tazobactam y cefepime. En el estudio se hizo comparación antes y después de la política de restricción antibiótica en infecciones nosocomiales por gérmenes gram negativos, encontrándose que de 2880 pacientes que ingresaron a UCIN, el 24,5% tuvo diagnóstico de infección y de ellos, el 30,7% correspondió a infecciones hospitalarias. De los gérmenes aislados el 49% correspondió a bacterias gram negativas, con una producción de BLEEs en el 51% de los aislados de Klebsiella pneumoniae, de 28% en los de Escherichia coli, de 14% en los de Acinetobacter baumannii y de 7% en los de Serratia. En el 70% de los casos con presencia de BLEEs se habían utilizado cefalosporinas de III generación. Luego de la restricción de cefalosporinas de III generación se observó una importante disminución en los aislamientos de los gérmenes productores de resistencia betalactámica (del 20% en el primer periodo, se bajó a menos del 4% en el segundo), es decir que el riesgo producir BLEEs disminuyó casi cinco veces, con una razón de prevalencia de 4,91(IC 95%: 1,14-21,09) y un valor de p=0,031 respecto al periodo anterior, pudiéndose concluir que la adopción de una política de restricción en el uso de antibióticos tuvo un significativo efecto reductor en la incidencia de BLEEs en la UCIN de nuestro hospital, disminuyendo a su vez los costos, pues se redujo el uso de carbapenems. Tendo em conta que o uso indiscriminado de antibióticos de amplo espectro favoreceu a apari o de resistência bacteriana a numerosos medicamentos, realizou-se um estudo de interven o experimental entre janeiro de 2002 e janeiro de 2006 na unidade de terapia intensivos neonatal (UTIN) do Hospital Militar Central de Bogotá, no que se restringiu o uso de cefalosporinas de III gera o mudando-as por antibióticos n o associados com indu o de beta-lactamasas de espectro estendido (BLEEs), utilizando piperazilina-tazobactam e cefepime. No estudo se fez compara o antes e depois da política de restri o antibiótica em infec es nosocomiais por bactérias gram negativos, encontrando-se qu

Infectio , 2011,
Abstract: introduction: hepatitis a is an infectious disease caused by a non-encapsulated rna virus of the picornaviridae family, classified as hepatovirus. it is transmitted by a fecal-oral route, either from person to person or in common source epidemics. objective: the aim of this study was to estimate the seroprevalence of igg antibodies against the hepatitis a virus in children aged 1-15 years, treated in a university hospital as part of a national collaborative study. methods: a descriptive study was performed between june and november 2007. the antibody titers were detected by means of a microparticle capture enzyme immunoassay. a survey to identify risk factors was conducted for each participant, with additional variables under study. results: we studied 422 children. the overall prevalence of antibodies against hepatitis a was 29.1%, with 37.1% in the group of 5 to 9 years of age, 36.1% for 10 to 15, and 13.8% for 1 to 4. the highest proportion of antibody prevalence was found in children of the lowest socioeconomic status, 44.2% for the stratum 1 and 27.9% for the stratum 2. conclusion: the seroprevalence to hepatitis a virus was lower in children with less than five years of age, which is an indication of a transition of the epidemiological profile to an intermediate one. the prevalence was higher in children of low socioeconomic levels, which may be related to overcrowding and poor hygiene practices
Endovascular approach of tibial peroneal trunk pseudo-aneurysm
Abello,Ana Lorena; Galvis,Víctor Raúl; Escobar,William;
Colombia Médica , 2010,
Abstract: this is a case report of a patient with tibioperoneal trunk pseudoaneurysm secondary to firearm injury. through endovascular intervention, two covered stents were placed on the lesion, with exclusion of the pseudoaneurysm and preservation of the vessel of origin. arterial doppler follow up 20 days after intervention revealed adequate stent permeability. in cases of complex extremity trauma with osteo-musculo-vascular involvement, endoluminal repair seems to be a useful tool in distal vessels.

A Geostatistical Approach to the Seasonal Precipitation Effect on Boro Rice Production in Bangladesh  [PDF]
Avit Kumar Bhowmik, Ana Cristina Costa
International Journal of Geosciences (IJG) , 2012, DOI: 10.4236/ijg.2012.33048
Abstract: Geographical assessments on the relationship between climate variability and crop production are important for planning adaptation programs to climate change impacts on Asian rice production. This paper analyses the seasonal precipitation consequences to irrigated crop yields, in opposition to the idea that irrigated crop yields are not affected by precipitation changes. Geostatistical methods are applied to assess changes in the patterns of seasonal precipitation and corresponding changes in the Boro crop production in Bangladesh. Surfaces depicting changes in the monsoon, non-monsoon and total precipitation from 2006 to 2007, and changes in three varieties of Boro crop yield and Total Boro yield from 2006-2007 to 2007-2008 crop year are generated through Splines, Inverse Distance Weighting and Ordinary Kriging methods. Performance evaluation of these models is also performed. The relationships between the surfaces of different precipitation seasons and the surfaces of different Boro yield seasons are then assessed. The results show that there is a significant correlation between seasonal precipitation changes and Boro yield changes with notable correlation coefficients and similarity in the patterns. A significant conformity of the high precipitation zones to the high Boro yielding zones is also depicted.

Delgado, Ana Cristina Coll;
Educa??o & Sociedade , 1998, DOI: 10.1590/S0101-73301998000200008
Abstract: this study aims at understanding how the integration of sociocultural issues occurs on the curricular proposal and teaching practice of a pre-school unit where professionals, joined to relatives and neighborhood, constructed within ten years a political-teaching project named "em busca de uma alternativa curricular" (searching for a curriculum alternative). the topics that conducted the investigation were: political-teaching project history and origin, interactions among different social actors, real curriculum and its demonstrations in the teaching practice, large and local culture, age and type relations.
Psicanálise e universidade: reflex?es sobre uma conjun??o ainda possível
Figueiredo, Ana Cristina;
Fractal : Revista de Psicologia , 2008, DOI: 10.1590/S1984-02922008000100022
Abstract: this paper approaches the relation between psychoanalysis and university. it begins with a historical approach in rio de janeiro since the 60's and examines the possibilities of psychoanalysis in undergraduate and postgraduate levels. the former only presents knowledge 'about' psychoanalysis. the latter may involve clinical work or a psychoanalyst's working through a master or doctoral thesis. the text presents the 'four discourse' theory formulated by lacan and discusses the transmission of psychoanalysis through teaching. it puts forward that this transmission is of a 'wish for knowledge' based on its lack which is the core of psychoanalytical approach to knowledge.
Molduras públicas de performatividade queer e representa??o mediática em Portugal
Santos,Ana Cristina;
Ex aequo , 2009,
Abstract: the media attention towards lgbt issues after the 1990s generated impacts on social representations of sexual orientation and gender identity, as well as on the portuguese lgbt movement itself, which was forced to an increased political reflexivity about its own individual and/or collective image. consequently, the subversive public display of the body is often excluded, even within the lgbt movement. such stance mirrors an ideological choice that tends to disconnect lgbt activism of its central role in deconstructing the dominant heteronormative and heterosexist culture, representing disengagement in relation to the queer venture. contributing to this debate are processes of ?normalization of homosexuality? which result from, and create, a narrow understanding of the frames of queer performativity considered (un)acceptable in the public sphere.
