Revista Espa?ola de Salud Pública , 2009, DOI: 10.1590/S1135-57272009000300011
Abstract: background: to study the renal function (fr) of the hypertensive patients by means of estimating equations and serum creatinine (crp). to calculate the percentage of patients with chronic kidney disease (erc) that present normal values of crp. to analyze which factors collaborate in the deterioration of the fr. methods: descriptive cross-sectional study of patients with hta. crp and arterial tension (ta) were determined. the glomerular filtration rate was calculated by means of cockroft-gault and mdrd's formula. the years of evolution of the hta were registered. a descriptive study of the variables and the possible dependence among them was completed, using several times linear multiple regression. results: 52 patients were studied (57,7% women). average age 72,4 ± 10,8. 32,6% (cockcroft-gault) or 21,5% (mdrd) were fulfilling erc criterion. the erc was mainly diagnosed in females. 21,4% (cockcroft-gault) and 9,5 % patients (mdrd) with erc had normal crp values. we do not find linear dependence between the numbers of ta and the fr. the ta check-up objectives do not suppose less development of erc. in males we find linear dependence within the fr (mdrd) and the years of evolution of the hta. conclusion: the erc is a frequent pathology in the hypertense persons. the systematical utilization of estimating equations facilitates the detection of hidden erc in patients with normal crp.
Prevalencia de los factores de riesgo de fractura por fragilidad en varones de 40 a 90 a?os de una zona básica de salud rural
Gómez Navarro,Rafael;
Revista Espa?ola de Salud Pública , 2011, DOI: 10.1590/S1135-57272011000500008
Abstract: background: osteoporosis and as a consequence fragility fractures have emerged in recent years as a major public health issue in developed countries. although its epidemiology and risk factors in postmenopausal women are well known, few studies exist focused on analyzing this pathology in men. our objective is to determine the prevalence of fragility fracture risk factors in men belonging to our population and to calculate the absolute risk of major osteoporotic fracture and hip fracture. methods: cross-sectional study conducted in a rural health basic area. the target population was composed by males between 40 and 90 years old. causes of exception were not considered. personal interviews were carried out collecting the following data: age, weight, height, body mass index (bmi), previous fractures, background on parent hip fracture, smoking habits, use of corticosteroids, background on rheumatoid arthritis, secondary osteoporosis, alcohol and bone mineral density (bmd). with this data, later in our health center, the absolute fracture risk and the hip fracture risk were calculated using the frax ? tool. results: 431 cases were studied. mean age 65,8 ± 13,9 years old and bmi 28,4 ± 4,3 kg/m2. bmd had not been determined for any of the patients. prevalence of risk factors: previous fracture 3,7%; parents with hip fractures 10,4%; smokers 21,1%; glucocorticoids 2,8%; rheumatoid arthritis 0,9%; secondary osteoporosis 2,3%; alcohol 30,9%. absolute fracture risk, 3,7 ± 3,1 95% ci (3,43-4,02); hip fracture risk 1,7 ± 2,5 95% ci (1,51-1,98). conclusion: particularly important for males, the elimination of alcohol and tobacco.
Aplicación de la herramienta FRAX? para la determinacion del riesgo de fractura en mujeres de un ámbito rural

Revista Espa?ola de Salud Pública , 2010, DOI: 10.1590/S1135-57272010000300009
Abstract: background: fractures induced by fragility are an important public health problem. to establish preventive interventions based on the absolute value of the fracture risk must turn into a priority. the objectives of this work are: to determine the absolute fracture risk in postmenopausal women and, depending on it, to consider the recommendations on the convenience of carrying out dexa and/or of initiating a treatment a with antiresorptive agents. methods: descriptive cross-sectional study realized in a rural population. all the women between 40 and 90 years old were studied. their fracture risk was calculated by means of the frax algorithm. to follow a treatment with antiresorptive agents and suffering a terminal illness were considered as a cause of exception. the recommendations regarding the request of dexa and/or of initiating treatment were based on the european guidance for the diagnosis and management of osteoporosis in postmenopausal women. results: the final number of studied women promoted 76, with a middle ages of 67,9 ± 13,4. in them, the absolute risk of osteoporotic fracture 8,1 ± 7,9 and the risk of hip fracture 3,7 ± 5,3. to request dexa is recommended in 9 (11,8 %) and to raise the beginning of treatment in 3 (3,9 %). in 9 (> 84 years), the guide does not establish recommendations. the necessary number of women to screen to indicate the accomplishment of one dexa is 8,4 and of 25,3 to initiate one treatment. we initiate it in the 3 recommended cases and in another one for which the guide does not indicate any recommendation. conclusion: frax alghorithm has facilitated to us the determination in a simple way of the absolute fracture risk and the hip fracture risk of the women of our population and has helped to us to decide to initiate treatment antirresortivo almost in 4 % of the studied ones.

Terapia y modificación de la conducta en el grupo familiar
Rafael Navarro Cueva
Revista de Psicología , 1983,
Abstract: Se hace una breve rese a de la evolución de la terapia comportamental. Se enfatiza el paso de un interés exclusivo por el organismo individual a grupos de organismos. Se analiza la aplicación de los principios conductuales al tratamiento del ni o y cómo lo anterior llevó a utilizar, primero, a los miembros de la familia como agentes de cambio y, luego, a conceptuar la familia como un sistema complejo de contingencias. Se revisa la concepción conductual de la familia y sus aplicaciones terapéuticas. A brief account of the development of Behavior Therapy is done with special emphasis on the evolution from an interest centered upon one organism to a concern for groups of organisms. An analysis is made about how the application of Behavior Therapy to the treatment of children made possible the utilization of the family as a change agent and a conceptualisation of the family as a complex system of contingencies. A revision is made of this view of the family and its applications.

Abstract: Gnaisses graníticos a trondhjemíticos da regi o de Pontalina, sul do estado de Goiás, mostram composi o cálcica acálcio-alcalina, metaluminosa a peraluminosa. Apresentam baixos teores em álcalis, enriquecimento em Ba, Sr, K, Rb emrela o ao Nb, Y, Zr e ETR e anomalias negativas de Nb e Ti, semelhantes à composi o química de magmas gerados emambientes de arcos magmáticos. Foram anteriormente interpretados como parte do embasamento da Faixa Brasília eatribuídos ao Arqueano e Paleoproterozóico, porém novos dados isotópicos Sm – Nd sugerem que estas rochas s oneoproterozóicas (TDM = 0,9 a 1,2 Ga) e os dados geoquímicos indicam que s o semelhantes a rochas de outras regi espertencentes ao Arco Magmático de Goiás.
Mechanism of radiation-induced degradation of bisphenol-A polycarbonate
Rafael Navarro González,Roustam Aliev
Revista de la Sociedad Química de México , 2001,
Abstract: Reportamos una nueva metodología para estudiar el mecanismo de degradación por radiación de materiales poliméricos basada en el análisis combinado de los gases de origen radiolítico, y los productos pirolíticos, generados mediante la pirólisis rápida de polímeros pre-irradiados, acoplado a cromatografía de gases espectroscopía de infrarrojo con transformada de Fourier espectrometría de masas por impacto electrónico. El policarbonato de bisfenol-A (PC) fue estudiado en el rango de dosis de 0.125 a 1.0 MGy. La irradiación del PC estuvo acompa ada por la liberación preferencial del monóxido de carbono seguida de una producción menor de hidrógeno, dióxido de carbono y metano. El PC pirolizado liberó principalmente dióxido de carbono, metano, benceno, tolueno y 4-metilfenol. Con base en los resultados obtenidos sugerimos dos vías principales para la incisión del PC por radiación con igual probabilidad: (a) ruptura del enlace carbonato y (b) ruptura del enlace alifáticoaromático.
