Sleep is fundamental for both health and wellness. The advent of "on a chip" and "smartphone" technologies have created an explosion of inexpensive, at-home applications and devices specifically addressing sleep health and sleep disordered breathing. Sleep-related smartphone Applications and devices are offering diagnosis, management, and treatment of a variety of sleep disorders, mainly obstructive sleep apnea. New technology requires both a learning curve and a review of reliability. Our objective was to evaluate which app have scientific publications as well as their potential to help in the diagnosis, management, and follow-up of sleep disordered breathing.We search for relevant sleep apnea related apps on both the Google Play Store and the Apple App Store. In addition, an exhaustive literature search was carried out in MEDLINE, EMBase, web of science and Scopus for works of apps or devices that have published in the scientific literature and have been used in a clinical setting for diagnosis or treatment of sleep disordered breathing performing a systematic review.We found 10 smartphone apps that met the inclusion criteria.The development of these apps and devices has a great future, but today are not as accurate as other traditional options. This new technology offers accessible, inexpensive, and continuous at home data monitoring of obstructive sleep apnea, but still does not count with proper testing and their validation may be unreliable.

Resumen Objetivo El objetivo de este estudio es crear y validar un cuestionario abreviado de la version espanola del Transsexual Voice Questionnaire for Male-to-Female Transsexuals (VeTVQMtF). Metodologia El estudio fue dirigido por 2 hospitales de referencia para la feminizacion quirurgica de la voz y por un departamento universitario de psicologia y rehabilitacion vocal, todos ellos en Espana. Material y metodos Se realizo un estudio prospectivo de 51 mujeres transexuales a las que se les intervino de feminizacion quirurgica de la voz entre enero 2017 y diciembre 2018. La VeTVQMtF fue rellenada por las mujeres transexuales antes y despues de la cirugia y los 10 items de este cuestionario que mas variaron fueron seleccionados por un grupo de expertos en feminizacion de la voz, para desarrollar la version abreviada de la VeTVQMtF (VeTVQMtF-10). Se estudio la correlacion entre la puntuacion total y la puntuacion de cada item en la VeTVQMtF y en la VeTVQMtF-10. Se analizo la consistencia interna de la VeTVQMtF-10. Resultados Se encontro una buena correlacion entre los 2 cuestionarios (coeficiente de Pearson > 0,90), una buena correlacion entre la puntuacion total y la puntuacion de cada item de la VeTVQMtF-10 y una correlacion negativa entre la de la VeTVQMtF y la frecuencia fundamental de la voz tras la cirugia. El α Cronbach fue de 0,79. Conclusion La VeTVQMtF-10 es una version abreviada valida de la VeTVQMtF y podria usarse para valorar la calidad de vida relacionada con la voz en mujeres transexuales en el idioma espanol.
