Background and purposeUrinary incontinence is one of the most serious complications of prostate cancer treatment. The objective of this study was to assess efficacy and safety of Adjustable Transobturator Male System (ATOMS) compared to Adjustable Continence Therapy (proACT) for male stress urinary incotinence according to literature findings.Material and methodsA systematic review and meta-analysis on adjustable devices ATOMS and ProACT is presented. Studies on female or neurogenic incontinence were excluded. Differences between ATOMS and proACT in primary objective: dryness status (no-pad or one safety pad/day) after initial device adjustment, and in secondary objectives: improvement, satisfaction, complications and device durability, were estimated using random-effect model. Statistical heterogeneity among studies included in the meta-analysis was assessed using tau2, Higgins´s I2 statistics and Cochran´s Q test.ResultsCombined data of 41 observational studies with 3059 patients showed higher dryness (68 vs. 55%; p = .01) and improvement (91 vs. 80%; p = .007) rate for ATOMS than ProACT. Mean pad-count (-4 vs. -2.5 pads/day; p = .005) and pad-test decrease (-425.7 vs. -211.4 cc; p < .0001) were also significantly lower. Satisfaction was higher for ATOMS (87 vs. 56%; p = .002) and explant rate was higher for proACT (5 vs. 24%; p < .0001). Complication rate for ProACT was also higher, but not statistically significant (17 vs. 26%; p = .07). Mean follow-up was 25.7 months, lower for ATOMS than ProACT (20.8 vs. 30.6 months; p = .02). The rate of working devices favoured ATOMS at 1-year (92 vs. 76; p < .0001), 2-years (85 vs. 61%; p = .0008) and 3-years (81 vs. 58%; p = .0001). Significant heterogeneity was evidenced, due to variable incontinence severity baseline, difficulties for a common reporting of complications, different number of adjustments and time of follow-up and absence of randomized studies.ConclusionsDespite the limitations that studies available are exclusively descriptive and the follow-up is limited, literature findings confirm ATOMS is more efficacious, with higher patient satisfaction and better durability than ProACT to treat male stress incontinence.
In this paper we describe how a Nintendo Wii remote control (known as the Wiimote) can be used in the design and implementation of several undergraduate-level experiments in a physics laboratory class. An experimental setup composed of a Wiimote and a conveniently located IR LED allows the trajectory of one or several moving objects to be tracked and recorded accurately, in both long and short displacement. The authors have developed a user interface program to configure the operation of the acquisition system of such data. The two experiments included in this work are the free fall of a body with magnetic braking and the simple pendulum, but other physics experiments could have been chosen. The treatment of the data was performed using Bayesian inference.
In this paper a process for estimating the Stefan–Boltzmann law constant is proposed through a study of the current–voltage curve of a 12 V bulb. The least squares treatment of the data allows the value of the constant to be determined with results that are in accordance with the data in the literature.
Título: Escala de desarrollo armónico. Una propuesta integradora para la evaluación del desarrollo infantil. Resumen: En el ámbito de la evaluación psicológica, cada vez más, los profesionales interesados en el desarrollo son sensibles a la necesidad de instrumentos capaces de integrar en su diseño el carácter sistémico y epigenético de este proceso. La mayoría de las explicaciones propuestas en las últimas décadas convergen en considerar el cambio evolutivo como el resultado de una compleja red de transacciones entre el sujeto y sus contextos de desarrollo a distintos niveles. La Escala de Desarrollo Armónico recoge elementos sensibles al dinamismo del proceso ontogenético: áreas y funciones de desarrollo que experimentan tensiones generadoras de cambios cuantitativos y cualitativos a través de diferentes niveles y etapas. Estas etapas, entendidas como "estados atractores" -concepto clave en la Teoría de Sistemas Dinámicos Autoorganizados-, pierden rigidez e integran la variabilidad. La escala aporta variables que permiten abordar simultáneamente la dimensión cuantitativa (el Cociente de Desarrollo Medio) y la calidad del proceso de desarrollo (el Indice de Armonía). Los primeros ensayos realizados desvelan su utilidad como un test de screening al servicio de la prevención desarrollo infantil. Palabras clave: Psicología del desarrollo; escalas de evaluación del desarrollo infantil; teoría de sistemas dinámicos; desarrollo armónico.Abstract: Professionals interested in the area of psychological assessment are becoming increasingly sensitive towards the need for instruments capable of integrating the systemic and epigenetic character of the developmental process into its design. Most of the proposals put forward in recent decades coincide in considering developmental change as the result of a complex network of transactions between the subject and its developmental contexts at different levels. The Scale of Harmonic Development combines elements sensitive to the dynamism of the ontogenetic process: areas and functions of development which experience generative tensions of quantitative and qualitative change across different levels and stages. These stages, understood as "attractor states -a key concept in the Self-organizing Dynamic Systems Theory-, lose rigidity and integrate variability. The scale provides variables which allow the quantitative dimension (the Average Development Quotient) and the quality of the process of development (the Index of Harmony) to be dealt with at the same time. Initial trials reveal their usefulness as a screening test to serve in child development prevention.
