RESUMO

Adaptive analog beamforming is a key technology to enable spatial control of millimeter-wave wireless signals radiated from phased array antennas (PAAs) which is essential to maximize the capacity of future mobile networks and to ensure efficient usage of scarce spectrum. Intermediate frequency-over-fiber (IFoF), on the other hand, is a promising technology for the millimeter-wave (mm-wave) mobile fronthaul due to its low complexity, high optical spectral efficiency, and low latency. The combination of IFoF and PAA is key to implement mm-wave mobile communications in a scalable, centralized, efficient, and reliable manner. This work presents, for the first time to the best of the authors' knowledge, an extensive outdoor measurement campaign where an experimental IFoF mm-wave wireless setup is evaluated by using PAAs with adaptive beamforming on the transmitter and receiver sides. The configuration of the experimental setup is according to 5G standards, transmitting signals wirelessly at 27 GHz central frequency in the n258 band. The employed PAAs are composed of 8-by-8 patch antenna arrays, allowing beam steering in the azimuth and elevation angles. Furthermore, different end-user locations, antenna configurations, and wireless scenarios are tested in the outdoor experiment, showing excellent EVM performance and achieving 64-QAM transmission over up to 165.5 m at up to 1.88 Gbit/s. The experimental results enable optimization of the experimental setup for different scenarios and prove the system's reliability in different wireless conditions. In addition, the results of this work prove the viability and potential of IFoF combined with PAA to be part of the future 5G/6G structure.

RESUMO

The challenge of moving towards the right to health for all -through the strategies for universal access to health and universal health coverage (universal health)- requires multiple conditions and actions. One of them is to have sufficient health workers, well distributed and with the skills and motivation needed for the transformation of health services and to provide comprehensive and quality responses to people and their communities. This article presents the results of a dialogue between academics from universities in the Americas, and reflects on four essential dimensions: planning, interprofessional training, social responsibility of academic centers, and the use of models of teaching-service-research. These dimensions are fundamental for a comprehensive training of health professionals that contributes to universal health coverage.

RESUMO

[RESUMEN]. El desafío de avanzar hacia la materialización del derecho a la salud para todos a través de la estrategia para el acceso y la cobertura universal de salud (salud universal) requiere de múltiples condiciones y acciones. Una de ellas es contar con trabajadores de la salud suficientes, bien distribuidos y con las competencias y motivación que hagan posible la transformación de los servicios de salud y proporcionen respuestas integrales y de calidad a las personas y sus comunidades. Este artículo, producto del diálogo de académicos de diversos centros universitarios de las Américas, reflexiona y enfatiza cuatro dimensiones esenciales: la planificación, la formación interprofesional, la misión o responsabilidad social de los centros formadores y el uso de modelos de docencia-servicio-investigación. Estas dimensiones deben ser atendidas para una formación integral de profesionales de salud que contribuyan a hacer factible la salud universal.

RESUMO

OBJECTIVES: To assess the preoperative urodynamic predictors of urinary incontinence (UI) 1 year after robot-assisted radical prostatectomy (RARP) and to design a nomogram capable of predicting its occurrence. MATERIALS AND METHODS: Our prospective study included 58 previously continent patients who underwent RARP, in most cases, bilateral nerve-sparing and bladder neck preservation. A urodynamic examination including a urethral pressure profile was performed preoperatively. Multivariate analysis was used to assess the predictors for the need to use 1 or more pads/day and a nomogram was constructed. RESULTS: There was a 20.6% incidence of UI at 1 year after RARP. Bladder compliance, maximum urethral closure pressure and the development of bladder outlet obstruction, correlated well with the incidence of UI on the multivariate analysis (p = 0.043, 0.001, and 0.05, respectively). CONCLUSION: Bladder compliance <27.8 ml/cm H2O, maximum urethral closure pressure <50.3 cm H2O and the bladder outlet obstruction are independent urodynamic factors correlating with UI after RARP. The new nomogram can objectively predict a patient likelihood of requiring 1 or more pads/day 1 year after RARP with a good accuracy.

RESUMO

OBJECTIVE: To develop recommendations for the design and implementation of adverse event notification systems based on the experiences of the Latin American countries. METHODS: Employing the qualitative Metaplán methodology, proposals were obtained from 17 experts on adverse event notification systems from Argentina, Brazil, Chile, Colombia, Cuba, Mexico, and Peru and three from the Pan American Health Organization. The characteristics, scope, barriers and constraints, data entry method, type of analysis, and information feedback on adverse event notification systems were reviewed and how to involve professionals in this process was discussed. The proposals were prioritized through an analysis of the responses, debate, and collective deliberation. RESULTS: A total of 73 recommendations were obtained on the characteristics that adverse event notification systems should have and 90 on barriers and constraints. There was agreement that legal security for professionals, a culture of safety in health facilities, incentives, a nimble system for providing professionals with results, and a single taxonomy are key to the successful implementation of adverse event notification systems, which must endeavor to protect patient safety in order to improve health care. CONCLUSIONS: Adverse event notification systems must be tailored to the needs of each health center. They exist to enable the health system to learn from experience. Confidentiality, anonymity, voluntary participation, a single taxonomy, and legal security for professionals are critical elements of adverse event notification systems.

RESUMO

OBJECTIVES: Urinary incontinence (UI) still remains one of the major functional complications after robot-assisted radical prostatectomy (RARP). As the cause for UI is multifactorial, it is quite difficult to make a prediction preoperatively. Considering intraoperative and postoperative risk factors, besides the preoperative ones, we designed an incontinence prediction model, administered 1 month after the surgery, in order to identify incontinent patients at 1 year. PATIENTS AND METHODS: We retrospectively reviewed 244 patients who underwent RARP at our institution. Only 209 patients had sufficient data, a 1-year follow-up and were continent preoperatively. The association of UI with the risk factors was assessed by univariable and multivariable regression models. RESULTS: There was a 17.2% global UI rate at 1 year after RARP. Only age-adjusted Charlson comorbidity index, erectile function assessed by International Index of Erectile Function-5, prostate volume, nerve-sparing status and 24-hour urine loss at 1 month correlated with UI (p = 0.032, 0.009, 0.031, 0.018 and <0.001, respectively). The accuracy of the prediction model of UI was 92.8% (c-index), with an area under the curve of 91.9%. CONCLUSION: Age-adjusted Charlson comorbidity index, International Index of Erectile Function-5, prostate volume, nerve-sparing status and 24-hour urine loss at 1 month after RARP can predict an individual's risk of UI at 1 year after RARP with good accuracy. Further external validation is required in order to generalize the use of this model.
