Background The study investigates the prognostic impact of sex and sex‐related differences in patients hospitalized with heart failure with mildly reduced ejection fraction (HFmrEF). More data regarding the characterization of patients and their outcomes in the presence of HFmrEF are needed. Methods and Results Consecutive patients hospitalized with HFmrEF (ie, left ventricular ejection fraction 41%–49% and signs or symptoms of HF) were retrospectively included at one institution from 2016 to 2022. Female patients were compared with male patients with regard to the primary end point of all‐cause mortality at 30 months (median follow‐up). Statistical analyses comprised Kaplan–Meier, multivariable Cox proportional regression analyses and propensity score matching. From a total of 2184 patients hospitalized with HFmrEF, 64.6% were male. Female patients with HFmrEF were older than male patients (median age 78 versus 73 years; P=0.001) and had lower rates of ischemic cardiomyopathy (46.6% versus 63.6%; P=0.001). Within the entire study cohort, sex was not associated with the risk of all‐cause mortality (hazard ratio [HR], 0.931 [95% CI, 0.797–1.088]; P=0.372). However, male sex was associated with a lower risk of HF‐related rehospitalization at 30 months (HR, 0.761 [95% CI, 0.600–0.966]; P=0.026), which was confirmed after multivariable adjustment (HR, 0.759 [95% CI, 0.592–0.973]; P=0.029) and propensity score matching (HR, 0.722 [95% CI, 0.539–0.967]; P=0.029). Conclusion Although almost two thirds of patients hospitalized with HFmrEF were male, sex was no predictor for the risk of all‐cause mortality at 30 months. However, female sex was associated with a higher risk of HF‐related rehospitalization. Registration URL: https://clinicaltrials.gov; Unique identifier: NCT05603390.

Molten salts are the most widely used thermal energy storage system in Concentrated Solar Power (CSP) plants, accounting for 50% of the installed capacity. Many studies have conducted life cycle assessments of the Greenhouse Gas (GHG) emissions produced within the CSP ecosystem; however, it has not yet been standardized for molten salt storage. This study compares GHG emissions of molten salt storage in CSP with conventional coal and natural gas power plants, to measure the environmental impact they can have in the CSP ecosystem. This was achieved with the use of simulations for 48 operational CSP plants worldwide using the system advisor model with their respective operation conditions. Results show that for the three configurations studied, CSP plants would result in annual 3,99 MMtCO2eq of emissions displaced when compared to a coal power plant and 1,61 MMtCO2eq compared to a natural gas power plant.

Background: There is limited data regarding the influence of lung compliance on the outcome of patients with cardiogenic shock (CS). Thus, a registry study was conducted to assess the prognostic influence of lung compliance in invasively ventilated patients with CS. Methods: Hospital records for consecutive invasively ventilated CS-patients from June 2019 to May 2021 were collected into a prospective registry. Our study evaluated the prognostic influence of lung compliance on 30-day all-cause mortality. Statistical analyses comprised t-tests, analysis of variance (ANOVA), Kruskal-Wallis-tests, Spearman’s correlation, Kaplan-Meier survival analyses, and Cox regression. Results: A total of 141 patients with CS requiring invasive mechanical ventilation were included. Stratification by quartiles revealed that patients with the lowest lung compliance (≤23.8 mL/cmH2O) experienced the highest mortality rates (77.1% vs. 66.7% vs. 48.6% vs. 51.4%; log-rank p = 0.018) both overall and among the subgroup of CS-patients with cardiac arrest (80% vs. 74% vs. 53% vs. 59%; log-rank p = 0.037). After stratifying by the median, patients with lung compliance

Im Zuge der steigenden Beteiligung in der Hochschulbildung und der damit einhergehenden Studienheterogenität stehen die Hochschulen vor Herausforderungen im Umgang mit der Vielfältigkeit der Studierendenschaft und der Etablierung relevanter Maßnahmen, die sich auf die Lebenswelt Studierender beziehen und ihre Bedarfe in den Konzeptions- und Entwicklungsprozess integrieren. Im Rahmen dieses Beitrag wird ein studierendenzentierter Ansatz zur online-gestützten Selbsteinschätzung von Studierenden dargestellt, mit dessen Hilfe Studierende einen Einblick in ihre eigene Studiensituation und datenbasiertes, individualisiertes Feedback erhalten.
