Causes of non-attachment to contraceptive methods
Existen diversas causas de abandono o desapego al tratamiento en usuarias de métodos anticonceptivos. De forma general, la percepción o asociación de efectos adversos con el método anticonceptivo representa la principal causa de abandono. La mayor parte de los efectos adversos de los métodos anticonceptivos se relaciona con ideas o creencias erróneas, basadas en mitos, que se transmiten a través del tiempo. Incluso la influencia de abandono o desapego viene apoyada por el propio médico, quien por falta de actualización y asesoramiento puede seguir anclado en el pasado y recomendar acciones, como los 'descansos' del tratamiento con anticoncepción hormonal combinada, que motivan el abandono o, lo que es peor, fracaso del método, con la consecuencia de un embarazo no deseado. Los factores intrínsecos al método pueden aumentar la tasa de abandono, cuando este no se adapta a las características específicas y preferencias des las pacientes. En un intento por disminuir la tasa de abandono se han desarrollado nuevas formulaciones de anticonceptivos hormonales, con la finalidad de reducir los efectos adversos y aportar beneficios adicionales que aumenten el apego al tratamiento.
[English] There are several causes of abandonment or detachment to treatment in users of contraceptive methods. In general, the perception or association of adverse effects with the contraceptive method represents the main cause of interruption. Most of the adverse effects of contraceptive methods are related to misconceptions or beliefs, based on myths, that are transmitted over time. Even the influence of abandonment or detachment is supported by the doctor himself, who for lack of updating and advice can remain anchored in the past and recommend actions, such as the 'breaks' of treatment with combined hormonal contraception, which motivate the abandonment or, which is worse, failure of the method, with the consequence of an unwanted pregnancy. The factors intrinsic to the method can increase the abandonment rate, when it does not adapt to the specific characteristics and preferences of the patients. In an attempt to reduce the dropout rate, new formulations of hormonal contraceptives have been developed, with the aim of reducing adverse effects and providing additional benefits that increase adherence to treatment
First Results from a Broadband Search for Dark Photon Dark Matter in the to eV range with a coaxial dish antenna
We present first results from a dark photon dark matter search in the mass
range from 44 to 52 () using a
room-temperature dish antenna setup called GigaBREAD. Dark photon dark matter
converts to ordinary photons on a cylindrical metallic emission surface with
area and is focused by a novel parabolic reflector onto a horn
antenna. Signals are read out with a low-noise receiver system. A first data
taking run with 24 days of data does not show evidence for dark photon dark
matter in this mass range, excluding dark photon - photon mixing parameters
in this range at 90% confidence level. This surpasses
existing constraints by about two orders of magnitude and is the most stringent
bound on dark photons in this range below 49 eV.Comment: 7 pages, 4 figure
The DUNE Far Detector Interim Design Report, Volume 3: Dual-Phase Module
The DUNE IDR describes the proposed physics program and technical designs of the DUNE far detector modules in preparation for the full TDR to be published in 2019. It is intended as an intermediate milestone on the path to a full TDR, justifying the technical choices that flow down from the high-level physics goals through requirements at all levels of the Project. These design choices will enable the DUNE experiment to make the ground-breaking discoveries that will help to answer fundamental physics questions. Volume 3 describes the dual-phase module's subsystems, the technical coordination required for its design, construction, installation, and integration, and its organizational structure
