title: Baicalein inhibits bacterial membrane modifications and induces ferroptotic-like damages to potentiate colistin killing via orchestrating cellular labile iron

description: Colistin holds clinical importance as a last resort therapy against infections caused by multidrug-resistant Gram-negative pathogens. In addition to well-studied plasmid-encoded <i>mcr</i> alleles, the adaptive mechanisms primed by host conditions are increasingly evidenced to be responsible for suboptimal efficacy of colistin in clinical practice, yet have long been neglected. Herein, we reported the identification of baicalein that potentiates colistin killing <i>in vitro</i> and <i>in vivo</i> by manipulating bacterial labile iron pool, where ferrous iron accumulates at the expense of ferric and total iron. This change in iron abundance leads to inactivation of the PmrA/B two-component system and subsequent PmrA/B-dependent lipopolysaccharide modifications, finally promoting colistin to bind and destabilize the bacterial membrane. Meanwhile, increased ferrous iron, in response to colistin-induced ROS, results in ferroptotic-like damage, which generates lethal reactive electrophilic species to deteriorate the essential cellular constituents. These data underscore an exploitable link between iron homeostasis and colistin susceptibility, as both primary and secondary actions of colistin respond to the shifts in cellular labile iron. To sum, this study offers a translationally viable regimen of baicalein-colistin combination against Gram-negative pathogen infection and reveals the cellular labile iron as a generally applicable target for developing next-generation colistin adjuvants.

title: Re-análisis bayesiano de la salud mental en inmigrantes latinoamericanos en España (2014-2020): Reporte estadístico suplementario

description: Este conjunto de datos contiene el reporte estadístico detallado y las simulaciones de Monte Carlo que respaldan la Carta al Director titulada "Erosión de la 'paradoja del migrante sano' en salud mental en España: re-análisis bayesiano en población latinoamericana (2014-2020)". El análisis utiliza los datos primarios de prevalencia de depresión autodeclarada reportados por Borrell et al. (2025) a partir de las Encuestas Europeas de Salud en España de los años 2014 y 2020.

Contenido del reporte (Epidat 4.0):

·         Población 1: Población nativa nacida en España.

·         Población 2: Inmigrantes procedentes de países de América Latina.

Metodología: Inferencia bayesiana para la diferencia de proporciones utilizando distribuciones a priori no informativas de Jeffreys (Beta 0.5, 0.5)

Simulaciones: Se realizaron 10.000 iteraciones para cada periodo para obtener las distribuciones posteriores y los intervalos de credibilidad (ICr) al 95%. 

Hallazgos clave documentados:

·         Año 2014: Se documenta una ventaja de salud mental significativa a favor del colectivo latinoamericano, con una diferencia de prevalencia media de 3,7% y un ICr 95% de [1,6% a 5,3%].

·         Año 2020: Se observa la erosión de dicha ventaja, con una diferencia media reducida al 1,4% y un ICr 95% que cruza el valor nulo [-0,5% a 3,0%], indicando que la "paradoja" se ha vuelto estadísticamente incierta.
