Las tecnologías de la información y la comunicación son el nuevo medio por el que se perpetúa el control y la desigualdad a través del maltrato y la violencia de género. Esta situación resulta aún más sangrante y menos visible en los casos de las mujeres con capacidades diferentes. Que las redes se conviertan en un espacio de libertad y no de control pasa inexcusablemente, por una educación en valores y para la igualdad, un uso responsable, respetuoso y adecuado de las redes sociales y la necesaria prevención y detección precoz de toda forma de violencia machista

Systematic Study of the Content of Phytochemicals in Fresh and Fresh-Cut Vegetables

Vegetables and fruits have beneficial properties for human health, because of the presence of phytochemicals, but their concentration can fluctuate throughout the year. A systematic study of the phytochemical content in tomato, eggplant, carrot, broccoli and grape (fresh and fresh-cut) has been performed at different seasons, using liquid chromatography coupled to triple quadrupole mass spectrometry. It was observed that phenolic acids (the predominant group in carrot, eggplant and tomato) were found at higher concentrations in fresh carrot than in fresh-cut carrot. However, in the case of eggplant, they were detected at a higher content in fresh-cut than in fresh samples. Regarding tomato, the differences in the content of phenolic acids between fresh and fresh-cut were lower than in other matrices, except in winter sampling, where this family was detected at the highest concentration in fresh tomato. In grape, the flavonols content (predominant group) was higher in fresh grape than in fresh-cut during all samplings. The content of glucosinolates was lower in fresh-cut broccoli than in fresh samples in winter and spring sampling, although this trend changes in summer and autumn. In summary, phytochemical concentration did show significant differences during one-year monitoring, and the families of phytochemicals presented different behaviors depending on the matrix studied

Social demand in ambulatory oral surgery. Experience in the Master of Oral Surgery of Madrid Complutense University (Spain)

Objectives. An evaluation is made of the surgical activity in the context of the Master of Oral Surgery (Madrid Complutense University, Madrid, Spain), together with an analysis of social demand in ambulatory oral surgery. Study design. A descriptive statistical analysis (frequency and contingency tables) is made of the different parameters relating to the activity carried out in this postgraduate master during two academic years. Results. A total of 6750 interventions were carried out in 5877 patients. Females predominated over males (62% versus 38%), and 59.2% of the subjects were in the 21-40 years age range. The most common procedure was tooth extraction (91%); of these, 83.5% corresponded to molars. Other extractions accounted for 5.5%, while impacted canines represented 1.2% of the interventions, cyst removal 1.2%, and periapical surgery 0.5%. Conclusions. Our results show third molar extraction to be the most commonly demanded intervention in ambulatory oral surgery

Metaanalysis of the epidemiology and clinical manifestations of odontomas

Objective: To evaluate the epidemiological and clinical aspects of the different types of odontomas. Study design: A metaanalysis was made of 3065 odontomas obtained from a literature review of 30 articles published in recent years. Results: Odontomas show no gender predilection, and are most often diagnosed in the second decade of life. They are preferentially located in the upper maxilla, particularly in the anterior sector. Compound odontomas are more prevalent than complex odontoma, and show no predilection in terms of patient gender, age or location. Most such lesions are asymptomatic and constitute casual findings in X-ray studies indicated for other reasons. The most common clinical manifestations are the retention of permanent teeth and the presence of a tumor. Treatment consists of surgical removal of the lesion. The prognosis is very good, with a scant tendency towards relapse. Conclusions: Odontomas are the most common odontogenic tumors. Their most significant characteristics comprise alterations in tooth eruption, and the diagnosis is casually established in the course of routine X-ray studies

Clinical and radiological course in apicoectomies with the Erbium : YAG LASER

Objective. A study is made of the efficacy of the Erbium:YAG laser in granulomatous periapical lesions, based on clinical and radiographic controls. Material and methods. The study comprised a series of 45 patients amenable to periapical surgical treatment of incisors, canines and premolars. A conventional surgical technique was used, with silver amalgam retrograde filling and irradiation of the bone defect and remnant root cement with the Erbium:YAG laser. Clinical and radiographic controls were made during 24 months, assessing the absence of symptoms and the presence of pain, swelling or fistula and ossification of the lesions, respectively. Results. The clinical course proved asymptomatic in 95.5% of the cases. As regards remodeling of the bone cavity, 77.7% had completed ossification after 24 months, 13.3% were in an advanced stage of ossification and 4.5% in an intermediate stage, while 4.5% showed treatment failure. Conclusions. The combination of silver amalgam and irradiation with the Erbium:YAG laser in periapical surgery showed a very high clinical success rate, with a 77.7% bone cavity remodeling rate after 24 months

Testing for signif cant differences between two spatial patterns using covariates

This is the accepted manuscript of the following article: Borrajo, M., González-Manteiga, W., & Martínez-Miranda, M. (2019). Testing for significant differences between two spatial patterns using covariates. Spatial Statistics, 100379. doi: 10.1016/j.spasta.2019.100379This paper addresses the problem of comparing the spatial distribution of two point patterns. A formal statistical test is proposed to decide whether two observed patterns share the same theoretical intensity model. This underlying model assumes that the first-order intensity function of the process generating the patterns may depend on covariate information. The test statistic consists of an $L_2$-distance between two kernel estimators for the corresponding relative density, which is shown to be asymptotically normal under the null hypothesis assuming that the underlying process is Poisson. In practice a suitable bootstrap method is proposed to calibrate the test. Simulations are used to explore the ability of the proposed test to identify different spatial patterns. An application to the analysis of wildfires in Canada shows the practicality of the proposal, with appealing conclusions regarding to the need of including covariate informationS

Bootstrapping kernel intensity estimation for inhomogeneous point processes with spatial covariates

This is the accepted manuscript of the following article: Borrajo, M., González-Manteiga, W., & Martínez-Miranda, M. (2020). Bootstrapping kernel intensity estimation for inhomogeneous point processes with spatial covariates. Computational Statistics & Data Analysis, 144, 106875. doi: 10.1016/j.csda.2019.106875The bias-variance trade-o for inhomogeneous point processes with covariates is theoretically and empirically addressed. A consistent kernel estimator for the rst-order intensity function based on covariates is constructed, which uses a convenient relationship between the intensity and the density of events location. The asymptotic bias and variance of the estimator are derived and hence the expression of its infeasible optimal bandwidth. Three data-driven bandwidth selectors are proposed to estimate the optimal bandwidth. One of them is based on a new smooth bootstrap proposal which is proved to be consistent under a Poisson assumption. The other two are a rule-of-thumb method based on assuming normallity, and a simple non-model-based approach. An extensive simulation study is accomplished considering Poisson and non-Poisson scenarios, and including a comparison with other competitors. The practicality of the new proposals is shown through an application to real data about wild res in Canada, using meteorological covariatesThis work has been partially supported by the Spanish Ministry of Economy and Competitiveness, through grants number MTM2013-41383P and MTM2016-76969P, which includes support from the European Regional Development Fund (ERDF).
