MediSur , 2007,
Abstract: Backgroud: Diabetes represents one of the medical conditions complicating pregnancy more frequently, and has the major repercussion not only on mother and foetus but also in the new born child. Objectives: To determine the maternal conditions that associate with the apparition of macrosomia on descendants. Methods: Analytical study that included 159 cases with gestational diabetes treated in the obstetric service of the Universitary Provincial Hospital ¨Dr. Gustavo Aldereguía Lima¨ de Cienfuegos, in the years 2003-2004. there were evaluated the maternal age, the parity, hypertension, gestational diabetes and macro foetus antecedents, nutritional values before pregnancy, skin colour, gestational time to diagnosis, PTG values at two hours, gestational time at delivery. A multivariate analysis was done through a logistic regression. Results and Conclusions: Obesity and gestational diabetes diagnosis over 23 weeks were the variable group that most associated with the apparition of macrosomia. Fundamento: La diabetes representa una de las condiciones médicas que con más frecuencia complican el embarazo y tiene la mayor repercusión no solo sobre la madre y el feto, sino también sobre el recién nacido. Objetivo: Determinar las condiciones maternas que se asocian con la aparición de macrosomía en la descendencia. Métodos: Estudio analítico que incluyó 159 gestantes con diabetes gestacional atendidas en el Servicio de Obstetricia del Hospital Provincial Universitario ¨Dr. Gustavo Aldereguía Lima¨ de Cienfuegos, en los a os 2003- 2004. Se evaluaron la edad materna, paridad, antecedentes de hipertensión, de diabetes gestacional y de macrofeto, valoración nutricional al inicio del embarazo, color de la piel, tiempo gestacional al diagnóstico, valor de la PTG a las 2 horas, tiempo gestacional al parto. Se realizó un análisis multivariado mediante una regresión logística. Resultados y Conclusioes: La obesidad y el diagnóstico de diabetes gestacional por encima de las 23 semanas fueron el grupo de variables que más se asociaron con la aparición de macrosomía.

Abstract: Background: Major congenital defects have an impact on perinatal mortality and morbidity with economic and social consequences. Objective: To determine the relevant risk factors linked to the occurrence of congenital defects in Cienfuegos between 2000 and 2005. Methods: A case-control study was carried out. Women with fetus or newborns with major congenital defects formed the case group (255) while the control group consisted of a similar number of healthy children selected each year by a randomized simple sample. The variables gathered by the Cuban Congenital Defects Records were studied. Chi-Square method was used with 95% of accuracy and a reliance rate of 95%; logistic regression was used with the Wald test. Results: There was a predominance of Central Nervous System defects (28, 6%). The most relevant risk factors were a history of congenital defects, smoking habits, and acute infection during the first three months, as well as belong to the third birth on. Conclusion: The most clinical relevant risks factors were the congenital defect history and the acute infection during the firs three months. Fundamento: Las malformaciones congénitas mayores influyen en la morbimortalidad perinatal, lo que tiene implicaciones sociales y económicas. Objetivo: Determinar los factores de riesgo relevantes, asociados a la aparición de malformaciones congénitas mayores, en la provincia Cienfuegos en el período 2000-2005. Métodos: Se realizó un estudio de casos y controles no pareados. Las mujeres registradas con fetos o recién nacidos con malformaciones congénitas mayores, constituyeron el grupo de casos (255), mientras que el grupo control estuvo conformado por un número similar de ni os sanos, seleccionados en cada a o, por un muestreo aleatorio simple. Se estudiaron las variables recogidas en el modelo del Registro Cubano de Malformaciones Congénitas modificado. Se utilizó el estadígrafo Chi cuadrado con una exigencia de precisión del 95 % y la razón de productos cruzados (OR) con un índice de confiabilidad (IC) = 95 %; se aplicó la regresión logística utilizando el método “adelante Wald”. Resultados: Predominaron las malformaciones correspondientes al Sistema Nervioso Central (28,6 %). Como factores de riesgo más relevantes se encontraron los antecedentes de malformaciones congénitas, el hábito de fumar, y de infección aguda durante el primer trimestre, así como ser hijo del tercer nacimiento en adelante. Conclusiones: Los factores de riesgo de mayor importancia clínica en su aparición, fueron el antecedente de malformación congénita y la infección aguda durante

Abstract: Fundament: Diabetes Mellitus is one of the most affecting diseases in the development of pregnancy. This greatly depends on the metabolic control achieved, which has demanded several proyects of treatment, thus decreasing the risks that the gestational process carries out. Objective: to compare the perinatal results between the diabetic gestational women and pregestational ones admitted at Cienfuegos Hospital. Method: Comparative study developed at the Gynecological-Obstetric Universitary Hospital from Cienfuegos province, from January to december 2003, including 167 pregnant women with Diabetes mellitus during pregnancy. The variables under study were: type of Diabetes, Márquez Guillén classification about good or bad fetal-maternal prognosis , treatment used, type of delivery, gestational age at labor, newborn weight, prenatal and maternal complication. Results: There was a predominance of gestational diabetes (73, 6 %) over the cases with pregestational diabetes (26,3 %). According to Marquez Guillén classification , the bad fetal-maternal prognosis (X=16.37, p < 0.05), the treatment with diet plus insulin(X=53.5, p < 0.05),abortio(X=32.2, p < 0.05),pre term delivery (X=11, p < 0.05),maternal morbidity (X=36.8, p < 0.05) and perinatal morbidity (X=39.6, p < 0.05) were the most frequent in pregestationaldiabetes than in gestational diabetes. Fundamento: La diabetes mellitus es una de las enfermedades que mayor repercusión tiene sobre el desarrollo y los resultados del embarazo, lo cual depende en gran medida del control metabólico alcanzado, para lo cual se han ideado numerosos protocolos de tratamiento, logrando por este medio minimizar el riesgo que el proceso gestacional lleva implícito. Objetivo: Comparar los resultados perinatales entre las diabéticas gestacionales y pregestacionales ingresadas en nuestro centro. Métodos: Estudio comparativo realizado en el Servicio de Obstetricia del Hospital Universitario ¨Dr. Gustavo Aldereguía Lima¨ de Cienfuegos desde enero a diciembre del 2003, en el que se incluyeron 167 gestantes con diabetes durante el embarazo. Se estudiaron las siguientes variables: tipo de diabetes, clasificación de Márquez Guillén (buen o mal pronóstico materno fetal), tratamiento usado, tipo de parto, tiempo gestacional al parto, peso del recién nacido, complicaciones perinatales y maternas. Resultados: Predominó la diabetes gestacional (73, 6 %) sobre los casos con diabetes pregestacional (26,3 %),el riesgo de mal pronóstico de la DMPG respecto a la DMG en este estudio fue de 2,41 IC 95 % (1,60;3,63) en relación al tratamiento con

Abstract: Background: Diabetes constitutes the most frequent medical complication during pregnancy, and it has a direct impact on the perinatal results. Objectives: To determine the effect of the diabetes on perinatal results. Methods: A descriptive study of series of cases was carried out. Of an universe of 13 603 childbirths from January 1st, 2003 to December 31st, 2005, in the Obstetric Service of the University Hospital ¨Dr. Gustavo Aldereguía Lima¨ in Cienfuegos, a sample of 229 pregnant women with diabetes was taken. Rates were determined for under weight, premature births, congenital malformations, late fetal deaths, macrosomia, asphyxia and assessment of caesarean operation in the diabetic women; as well as the risk of these complications for this group with regard to the non diabetic pregnant women and between the gestational and pre-gestational diabetes. Results: Diabetes incidence and pregnancy was of 1, 68 %. The risk of premature birth (17,4 %), of under weight of the newborn (13,1 %), macrosomia (15,3 %), malformations (3,5 %), neonatal death (0,4 %), late fetal death (0,9 %) and birth by Caesarean operation (64,2 %) was higher in the diabetic population, with regard to the non diabetic. The pre- gestational diabetes turned out to have bigger risks with regard to the gestational one regarding the premature childbirth, the most important congenital malformations and the late fetal deaths. Conclusion: Although the province shows a low incidence of diabetes in the pregnancy, the risk of adverse perinatal results is considerable for this group, especially in pre-gestational diabetic women. Fundamento: La diabetes constituye la complicación médica más frecuente en el embarazo, lo que incide directamente en los resultados perinatales. Objetivos: Determinar el efecto de la diabetes sobre los resultados perinatales. Métodos: Se realizó un estudio descriptivo, de serie de casos. De un universo de 13 603 partos realizados desde el 1ro de enero del 2003 al 31 de diciembre del 2005, en el Servicio de Obstetricia del Hospital Universitario “Dr. Gustavo Aldereguía Lima” de Cienfuegos, se tomó una muestra de 229 gestantes con diabetes. Se determinaron las tasas de bajo peso, prematuridad, malformaciones congénitas, muertes fetales tardías, macrosomía, asfixia y tasa de cesárea en las gestantes diabéticas; así como el riesgo de estas complicaciones para este grupo con respecto a las gestantes no diabéticas y entre la diabetes gestacional y pregestacional. Resultados: La incidencia de diabetes y embarazo fue de 1,68 %. El riesgo de prematuridad (17,4 %), de bajo pes

Inner Functions in Lipschitz, Besov, and Sobolev Spaces
Daniel Girela,Cristóbal González,Miroljub Jevti
Abstract and Applied Analysis , 2011, DOI: 10.1155/2011/626254
Abstract: We study the membership of inner functions in Besov, Lipschitz, and Hardy-Sobolev spaces, finding conditions that enable an inner function to be in one of these spaces. Several results in this direction are given that complement or extend previous works on the subject from different authors. In particular, we prove that the only inner functions in either any of the Hardy-Sobolev spaces with 1/≤<∞ or any of the Besov spaces , with 0<,≤∞ and ≥1/, except when =∞, =0, and 2<≤∞ or when 0<<∞, =∞, and =1/ are finite Blaschke products. Our assertion for the spaces 0∞,, 0<≤2, follows from the fact that they are included in the space VMOA. We prove also that for 2<<∞, VMOA is not contained in 0∞, and that this space contains infinite Blaschke products. Furthermore, we obtain distinct results for other values of relating the membership of an inner function in the spaces under consideration with the distribution of the sequences of preimages {?1()}, ||<1. In addition, we include a section devoted to Blaschke products with zeros in a Stolz angle.
Oscillatory Solutions for Second-Order Difference Equations in Hilbert Spaces
Cristóbal González,Antonio Jiménez-Melado
Advances in Difference Equations , 2007, DOI: 10.1155/2007/86925
Abstract: We consider the difference equation ”2xn+f(n,xn+ )=0, =0,1, ¢ € |, in the context of a Hilbert space. In this setting, we propose a concept of oscillation with respect to a direction and give sufficient conditions so that all its solutions be directionally oscillatory, as well as conditions which guarantee the existence of directionally positive monotone increasing solutions.

Abstract: Fueron estudiadas la anatomía y la ontogenia de las semillas de H. Lhotzkyana, con el fin de conocer la estructura y el origen de su aleta. Fueron analizadas semillas maduras de H. baruensis, representante del género, con el fin de comparar los dos tipos de semillas. La exotesta está constituída por esclereidas alargadas longitudinalmente, la endotesta está formada por células parenquimáticas con peque os grupos de células taníferas. El principal mechanical layer de la semilla es el exotegmen, formado por macroesclereidas radialmente alargadas, el meso y endotegmen son taniníferos. El presente estudio muestra que la aleta de las semillas de H. Lhotzkyana se desarrolla a partir del rafe, and consists of parenchymatic cells sourronding the rapheal vascular bundle and both sclerenchymatic epidermis
Asymptotic Behavior of Solutions to a Vector Integral Equation with Deviating Arguments
Cristóbal González,Antonio Jiménez-Melado
Abstract and Applied Analysis , 2013, DOI: 10.1155/2013/957696
Abstract: In this paper, we propose the study of an integral equation, with deviating arguments, of the type in the context of Banach spaces, with the intention of giving sufficient conditions that ensure the existence of solutions with the same asymptotic behavior at as . A similar equation, but requiring a little less restrictive hypotheses, is In the case of , its solutions with asymptotic behavior given by yield solutions of the second order nonlinear abstract differential equation with the same asymptotic behavior at as . 1. Introduction From the pioneering work of Atkinson [1], and subsequent works found in the literature (see, e.g., [2–10] for recent papers on the subject), we consider the following differential problem, with deviating arguments: with the task of finding solutions with the same behavior at as . Solutions with this prescription are given by the solutions of the following integral equation: which, by writing = , is of the type The purpose of this note is to provide conditions that ensure the existence of solutions to the above integral equation, whose asymptotic behavior at is the same as that of , thus giving a procedure to show existence of solutions with prescribed asymptotic behavior of differential equation of the type (1). Our wish is to also work out this integral equation in the setting of Banach spaces. Denote by the set of nonnegative real numbers. Assume that is a finite set of continuous mappings from to , that is a Banach space (with norm ), and also that is a continuous mapping from to . Finally, assume that is a given continuous mapping with certain regularity and integrability conditions, to be specified later. In order to give a better aspect to our equation, define, for each continuous , the mapping given by Then, our equation becomes which, by writing , , is transformed into A bit more of notation and preliminary results are needed. As customary, denotes the open ball in centered at with radius . The closure in of any set is written , and its closed convex hull, . The space of continuous -valued functions defined on is denoted by , while the space of bounded ones is . The latter is a Banach space when endowed with the sup norm , (i.e., for , ). The Schauder fixed point theorem states that any continuous operator defined on a nonempty, bounded, closed and convex subset of a Banach space has necessarily a fixed point, provided that is a relatively compact subset of . We will also be needing a well-known version of the Arzelà-Ascoli theorem which, in the case that occupies us, is as follows: if a family is equicontinuous at

Abstract: This 26-month follow up multi-centre trial, will include 1200 overweight/obese patients. Random assignment of the intervention by Basic Health Areas (BHA): two geographically separate groups have been created, one of which receives group motivational intervention (group intervention), delivered by a nurse trained by an expert phsychologist, in 32 group sessions, 1 to 12 fortnightly, and 13 to 32, monthly, on top of their standard program of diet, exercise, and the other (control group), receiving the usual follow up, with regular visits every 3 months.By addressing currently unanswered questions regarding the maintenance in weight loss in obesity/overweight, upon the expected completion of participant follow-up in 2012, the IMOAP trial should document, for the first time, the benefits of a motivational intervention as a treatment tool of weight loss in a primary care setting.ClinicalTrials.gov Identifier: NCT01006213Overweight and obesity are growing health problems throughout the industrialised world. If not controlled, it then will continue to contribute to the burden of non-transmitable diseases, which is increasing constantly. There is currently clear scientific evidence of the association of obesity and a large number of diseases and their manifestations, including: diabetes, hypertension, dyslipidemia, cardiovascular events and inflammatory markers such as plasma fibrinogen levels and C-reactive protein [1,2].Overall mortality for cardiovascular causes increases with weight [3,4] and, in the Framingham study, obesity was seen to be an independent risk factor for CVR regardless of other risk factors such as type 2 diabetes mellitus, dyslipidemia and smoking [5,6]; at the same time, overweight and obesity in adults significantly reduces life expectancy, in both women and men and smokers and non-smokers [7].The prevalence of obesity is increasing continuously in developed countries, causing a serious public health problem.
