Thermal co-evaporation of halide perovskites is a solution-free, conformal, scalable, and controllable deposition technique with great potential for commercial applications, particularly in multi-junction solar cells. Monolithic triple-junction perovskite solar cells have garnered significant attention because they can achieve very high efficiencies. Nevertheless, challenges arise in fabricating these devices, as they require multiple layers and precise current matching across complex absorber stacks. Here we demonstrate a current-matched monolithic all-perovskite p–i–n triple-junction solar cell enabled by controlled thermal co-evaporation of various absorber layers in the stack. The top and middle subcells were fabricated by developing optimized thermally co-evaporated Cs0.3FA0.7Pb(I0.56Br0.44)3 (1.80 eV bandgap) and FAPbI3 (1.53 eV) perovskites, respectively, while the bottom subcell employed a solutionprocessed Cs0.25FA0.75Pb0.5Sn0.5I3 (1.25 eV) perovskite. By optimising absorber thicknesses and compositions through optical modelling, we achieve excellent current matching between the top (9.6 mA cm−2 ), middle (9.3 mA cm−2 ), and bottom subcells (9.0 mA cm−2 ), achieving an overall efficiency of 15.8%. Optical modelling simulations suggest that current matching and efficiency up to 11.4 mA cm−2 and 37.6% respectively could be attainable using the latest interlayer materials. This work highlights the potential of scalable vapour-based deposition techniques for advancing multi-junction perovskite-based solar cells, paving the way for future developments in this field

Background/Objectives: To analyze the macular pigment optical density (MPOD) values in a child population and to evaluate the relation between MPOD and adherence to the Mediterranean diet using a validated questionnaire specially created for children. Eighty-eight children were included in this cross-sectional study from two primary education schools of Seville (Spain). Methods: MPOD values were measured using Macular Pigment Screener II ®. Lutein and Zeaxanthin intake was evaluated by KIDMED questionnaire, which classifies children according to adherence to the Mediterranean diet. A whole ocular exam with slit-lamp biomicroscopy was conducted by a specialized optometrist. Results: The mean age ranged between 6 and 8 years. The mean MPOD value was 0.46 ± 0.18. The mean score of the KIDMED questionnaire was 7.19 ± 1.85. No statistically significant differences were found as a function of gender or among Mediterranean diet adherence groups. No significant differences in MPOD values between answers were found in any KIDMED questions. No correlations were found for MPOD with several variables, such as Mediterranean diet adherence and KIDMED score. Conclusions: MPOD levels in children could not be correlated with Mediterranean Diet adherence and, thus, good dietary habits. Genetic characteristics, mother’s diet habits, oxidative stress, and body fat composition in children could be the main factors influencing MPOD levels.

Introduction: This study aimed to investigate the effcacy and safety of quantum molecular resonance (QMR) electrotherapy in patients with dry eye disease (DED).
Methods: A systematic review with metaanalysis, reporting the effects of QMR electro therapy in three databases, PubMed, Scopus and Web of Science, was performed according to the PRISMA statement with a search period ending on December 24, 2024.
Results: Seven studies, including four open-label, non-comparative trials and three randomized controlled studies (RCTs), were included. Although all studies reported signif cant improvements in most outcome measures after QMR electrotherapy, the meta-analysis indicated that overall effcacy did not signif cantly favor either group when comparing QMR electrotherapy to controls (SMD 0.40; 95% CI − 0.06 to 0.86; P = 0.09; I 2 = 85%). However, only the change in DED symptoms was signif cantly favorable for QMR electrotherapy com pared to controls (SMD 0.69; 95% CI 0.30–1.08; P = 0.0005; I 2 = 28%). In sensitivity analyses, overall effcacy remained non-signifcant when comparing QMR electrotherapy to placebo QMR electrotherapy (SMD 0.14; 95% CI − 0.24 to 0.52; P=0.46; I 2 =65%). Additionally, changes in DED symptoms, TBUT, ST, and CFS also showed no statistically signifcant differences between both groups. Regarding safety, most studies reported no AEs, with a satisfactory tolerability profle for QMR electrotherapy. However, a meta-analysis could not be performed.
Conclusions: With the current scientifc litera ture available to date, QMR electrotherapy seems to show some evidence of alleviating DED symp toms. However, evidence supporting its effcacy in improving DED signs and safety remains lim ited. Therefore, further RCTs with robust designs are needed to confrm these fndings.
Background: Echinocandins are recommended as firstline therapy in patients with candidemia. However, there is debate on their efficacy in survival outcomes. The aim of this study is to evaluate whether the choice of initial antifungal therapy improves mortality in patients with candidemia in relation to the presence of septic shock.
Methods: Patients with candidemia hospitalized in internal medicine wards of 5 tertiary care centers were included in the study (December 2012–December 2014). Patient characteristics, therapeutic interventions, and outcome were reviewed. Propensity score (PS) was used as a covariate of the multivariate analysis to perform a stratified analysis according to PS quartiles and to match patients receiving “echinocandins” or “azoles.”
Results: Overall, 439 patients with candidemia were included in the study. A total of 172 (39.2%) patients had septic shock. Thirty-day mortality was significantly higher in patients with septic shock (45.3%) compared with those without septic shock (31.5%; P = .003). Among patients with septic shock, the use of echinocandins in the first 48 hours, compared with azoles, did not affect 30-day mortality in the PS-adjusted Cox regression analysis (hazard ratio [HR], 0.77; 95% confidence interval [CI], 0.37–1.59; P = .48), the PS-stratified analysis, or the logistic regression model in matched cohorts (adjusted HR, 0.92; 95% CI, 0.51–1.63; P = .77).
Conclusions: Echinocandin therapy seems not to improve the outcome of non–intensive care unit patients with septic shock due to candidemia. These findings support the urgent need of further studies in this patient population.

El reciente RD 893/2024, de 10 de septiembre, por el que se regula la protección
de la seguridad y la salud en el ámbito del servicio del hogar familiar, viene a cubrir la
laguna sostenida durante casi treinta años a raíz de su exclusión del ámbito de aplicación
de la Ley 31/1995, de 8 de noviembre, de prevención de riesgos laborales. Siendo innegable
la necesidad de protección de esta prestación ante factores que no han de infravalorarse, la
norma plantea una tutela “en diferido”, quedando aspectos cruciales a la concreción por las
pertinentes herramientas informáticas. Exhibe, además, un carácter muy estético, con ciertos
olvidos y dificultades exegéticas y alguna solución alejada de la realidad del domicilio y las
particularidades de las personas trabajadoras domésticas y de quien aprovecha su prestación
