Low-Cost Materials for Do-It-Yourself (DIY) Installation of House Screening against <em>Aedes aegypti</em>
House-screening (HS) using fixed-aluminium frames to reduce the risk of indoor infestation with Aedes aegypti mosquitoes as well as the risk of Aedes-transmitted diseases in communities living in endemic areas. However, the success of this approach has been hindered by the elevated cost of the aluminium-based materials as well as their professional installation, which cannot be afforded by people living under vulnerable conditions. Cost-saving strategies such as the use of low-cost materials including wood, PVC, and Velcro are within the list of HS options available and offered by HS businesses and/or Do-it-yourself (DIY) packages verbi gratia ready-made and ready-to-install mosquito-screens. Here, we evaluated the efficacy of low-cost frames constructed with different materials to protect against Ae. aegypti indoor infestation using experimental huts. The efficacy of protection in preventing female mosquito passing inside the huts of any of the options of frames was high (>93%) compared to the control with no-screen. People’s perceptions on the different materials showed the most “popular” alternative was the frame made of wood (62%). All the prototype-frames of HS made of different materials were effective at blocking Ae. aegypti entering-mosquitoes particularly, low-cost options like magnets and Velcro
FSR 1716: A New Milky Way Globular Cluster Confirmed Using VVV RR Lyrae Stars
We use deep multi-epoch near-IR images of the VISTA Variables in the Vía Láctea (VVV) Survey to search for RR Lyrae stars toward the Southern Galactic plane. Here, we report the discovery of a group of RR Lyrae stars close together in VVV tile d025. Inspection of the VVV images and PSF photometry reveals that most of these stars are likely to belong to a globular cluster that matches the position of the previously known star cluster FSR 1716. The stellar density map of the field yields a >100? detection for this candidate globular cluster that is centered at equatorial coordinates R.A. J2000 = 16:10:30.0, decl. J2000 = ?53:44:56 and galactic coordinates l = 329.77812, b = ?1.59227. The color–magnitude diagram of this object reveals a well-populated red giant branch, with a prominent red clump at K s = 13.35 ± 0.05, and J ? K s = 1.30 ± 0.05. We present the cluster RR Lyrae positions, magnitudes, colors, periods, and amplitudes. The presence of RR Lyrae indicates an old globular cluster, with an age >10 Gyr. We classify this object as an Oosterhoff type I globular cluster, based on the mean period of its RR Lyrae type ab, days, and argue that this is a relatively metal-poor cluster with [Fe/H] = ?1.5 ± 0.4 dex. The mean extinction and reddening for this cluster are and E(J ? K s ) = 0.72 ± 0.02 mag, respectively, as measured from the RR Lyrae colors and the near-IR color–magnitude diagram. We also measure the cluster distance using the RR Lyrae type ab stars. The cluster mean distance modulus is (m ? M)0 = 14.38 ± 0.03 mag, implying a distance D = 7.5 ± 0.2 kpc and a Galactocentric distance R G = 4.3 kpc

Pharmacological management of antifungal agents in pulmonary aspergillosis: an updated review
Introduction: Aspergillus may cause different types of lung infections: invasive, chronic pulmonary or allergic bronchopulmonary aspergillosis. Pharmacological management with antifungals poses as a challenge. Patients diagnosed with pulmonary aspergillosis are complex, as well as the problems associated with antifungal agents. Areas covered: This article reviews the pharmacology of antifungal agents in development and currently used to treat pulmonary aspergillosis, including the mechanisms of action, pharmacokinetics, pharmacodynamics, dosing, therapeutic drug monitoring and safety. Recommendations to manage situations that arise in daily clinical practice are provided. A literature search of PubMed was conducted on November 15th, 2020 and updated on March 30th, 2021. Expert opinion: Recent and relevant developments in the treatment of pulmonary aspergillosis have taken place. Novel antifungals with new mechanisms of action that extend antifungal spectrum and improve pharmacokinetic-related aspects, drug-drug interactions and safety are under current study. For those antifungals already marketed, new data related to pharmacokinetics, pharmacodynamics, dose adjustments in special situations, therapeutic drug monitoring and safety are available. To maximize efficacy and reduce the risk of associated toxicities, it is essential to choose the most appropriate antifungal; optimize its dose, interval, route of administration and length of treatment; and prevent side effects
Tratamientos Psicológicos Empíricamente Apoyados Para la Infancia y Adolescencia: : Estado de la Cuestión
Background: The empirical
evidence accumulated on the effi cacy, effectiveness, and effi ciency of
psychotherapeutic treatments in children and adolescents calls for an
update. The main goal of this paper objective was to carry out a selective
review of empirically supported psychological treatments for a variety
of common psychological disorders and problems in childhood and
adolescence. Method: A review was carried out of the psychological
treatments for different psychological disorders and problems in socialemotional or behavioral adjustment in the child-adolescent population
according to the Spanish National Health System (Clinical Practice
Guidelines) levels of evidence and degrees of recommendation. Results:
The fi ndings suggest that psychological treatments have empirical
support for addressing a wide range of psychological problems in these
developmental stages. The degree of empirical support ranges from low
to high depending on the phenomenon analyzed. The review suggests
unequal progress in the different fi elds of intervention. Conclusions:
From this update, psychologists will be able to make informed decisions
when implementing those empirically supported treatments to address the
problems that occur in childhood and adolescence.Antecedentes: la evidencia empírica acumulada en los últimos años sobre
la efi cacia, efectividad y efi ciencia de los tratamientos psicológicos en la
infancia y adolescencia reclama una actualización. El principal objetivo
de este artículo es el de llevar a cabo una revisión de los tratamientos
psicológicos empíricamente apoyados para una diversidad de problemas
psicológicos habituales en la infancia y la adolescencia. Método:
se revisan los tratamientos psicológicos para diferentes trastornos
psicológicos y problemas en el ajuste socioemocional o conductual en
población infanto-juvenil en función de los niveles de evidencia y grados
de recomendación del Sistema Nacional de Salud de España (Guías de
Práctica Clínica). Resultados: los hallazgos sugieren que los tratamientos
psicológicos específi camente dirigidos a niños, niñas y adolescentes
disponen de apoyo empírico para el abordaje de un amplio elenco de
problemas psicológicos. Este grado de apoyo empírico oscila de bajo a
alto en función del problema analizado. La revisión muestra un avance
desigual en los diferentes campos de intervención. Conclusiones: a partir
de esta actualización, los profesionales de la psicología podrán tomar
decisiones informadas a la hora de implementar aquellas intervenciones
psicológicas con apoyo empírico para el abordaje de los problemas en la
infancia y la adolescenci
