Estudio de coberturas de vacunación y registro de vacunas en Coronel Vidal, General Pirán y Vivoratá / Study of vaccination coverage and vaccine registration in Coronel Vidal, General Pirán and Vivoratá

INTRODUCCIÓN La vacunación en adultos y adolescentes no alcanza los niveles deseables. Es fundamental mejorar el conocimiento en relación a coberturas, para orientar las políticas de salud. OBJETIVOS Conocer las coberturas de vacunación de adultos y adolescentes y la proporción que tienen registro de vacunas, Evaluar concordancia entre registros escritos y autoreporte, Evaluar factores asociados a esquemas incompletos. METODOLOGÍA Estudio transversal, en hogares, de adultos y adolescentes que viven en Coronel Vidal, General Pirán y Vivoratá. RESULTADOS El 23,8% de los encuestados, presentó registro de vacunación. Los adolescentes (67,9% con registro), presentaron coberturas de vacunación más elevadas en todas las vacunas respecto de los adultos. El 57,7% de adolescentes presentó esquema completo mientras que solo el 16,8% de los adultos lo tuvo. Las vacunas con mejores coberturas en adolescentes fueron doble/triple viral; 97,9%, antitetánica (últimos 10 años); 94,7% y hepatitis B; 98,5%. Las coberturas de HPV fueron bajas (76,4%) y solo el 64,6% completó el esquema. En adultos la vacuna con mejor cobertura fue antitetánica 64,4%. Solo el 36,2% de personas con factor de riesgo tenía registro de vacunas. La cobertura de influenza fue del 57,1%. Las vacunas que mejor concordancia presentaron entre autoreporte y registro fueron HPV y gripe, siendo baja en todo el resto. Entre los adolescentes el no tener médico de cabecera se asoció a esquemas incompletos. DISCUSIÓN El registro y coberturas de vacunación son bajos en adultos. Los adolescentes presentan mejores coberturas para algunas vacunas y más proporción de registro

Reconstruction of complex dynamical systems affected by strong measurement noise.

This Letter reports on a new approach to properly analyze time series of dynamical systems which are spoilt by the simultaneous presence of dynamical noise and measurement noise. It is shown that even strong external measurement noise as well as dynamical noise which is an intrinsic part of the dynamical process can be quantified correctly, solely on the basis of measured time series and proper data analysis. Finally, real world data sets are presented pointing out the relevance of the new approach.

Reducing stochasticity in the North Atlantic Oscillation index with coupled Langevin equations.

We present a critical investigation of the functional relationship between the two pressure time series routinely used to define the index characterizing the North Atlantic Oscillation (NAO), well known to regulate global climate variability and change. First, by a standard Markov analysis we show that the standard NAO index based on the pressure difference is not optimal in the sense of producing sufficiently reliable forecasts because it contains a dominating stochastic term in the corresponding Langevin equation. Then, we introduce a variationally optimized Markov analysis involving two coupled Langevin equations tailored to produce a NAO quasi-index having the desired minimum possible stochasticity. The variationally optimized Markov analysis is very general and can be applied in other physical situations involving two or more time series.

Discrete model for laser driven etching and microstructuring of metallic surfaces.

We present a unidimensional discrete solid-on-solid model evolving in time using a kinetic Monte Carlo method to simulate microstructuring of kerfs on metallic surfaces by means of laser-induced jet-chemical etching. The precise control of the passivation layer achieved by this technique is responsible for the high resolution of the structures. However, within a certain range of experimental parameters, the microstructuring of kerfs on stainless steel surfaces with a solution of H3PO4 shows periodic ripples, which are considered to originate from intrinsic dynamics. The model mimics a few of the various physical and chemical processes involved and within certain parameter ranges reproduces some morphological aspects of the structures, in particular ripple regimes. We analyze the range of values of laser beam power for the appearance of ripples in both experimental and simulated kerfs. The discrete model is an extension of one that has been used previously in the context of ion sputtering and is related to a noisy version of the Kuramoto-Sivashinsky equation used extensively in the field of pattern formation.
