Authors: Lopez-Miranda J. Luis , Elizalde-Mata Alberto , Esparza Rodrigo , Estevez Miriam 
Published: February 2025

Abstract
The massive influx of Sargassum spp. to the Mexican Caribbean coasts poses significant environmental, economic, and health challenges. This study explores the potential use of Sargassum spp. as a biosorbent material for contaminant removal. Some of the pollutants found in water bodies in some coastal areas are those derived from soaps and detergents, such as sulfates and phosphates. Therefore, the biosorbent capacity of Sargassum spp. to remove this type of substance dissolved in water was studied. The removal efficiency, for both pollutants, was greater than 90% when a concentration of 900 mg*L−1 was used. The capacity of Sargassum spp. to be used in several cycles was demonstrated, maintaining its biosorbent capacity. The structural changes in Sargassum spp. after biosorption were characterized by scanning electron microscopy, demonstrating the presence of sulfates and phosphates on Sargassum spp. Therefore, this work proposes an efficient, economic, and sustainable removal system based on Sargassum spp.

Application of Karhunen-Loève Transform Algorithms in Hydrogeological Parameter Compression: A Comparative Study
Authors: Yue Chao , Wang Jianping , Wang Zitao 
Published: February 2025

ABSTRACT
This paper proposes a parameter compression method using the Karhunen-Loève Transform (K-L) to reduce the computational burden of parameter inversion in groundwater models. Two spatial distributions of hydraulic conductivity (K) were generated using Kriging interpolation and Sequential Gaussian Simulation (SGS), and the K-L transform was applied to reduce their dimensionality. The method’s generality was assessed by varying model boundaries, extreme values of K, and simulation periods. The results showed that sequentially adding different boundary conditions resulted in high accuracy in model output. The model was most accurate when K values were within the range of 50-100 m/d, and its performance decreased as the range of K expanded. The model also exhibited high accuracy across various time periods within a single stress period. Dimensionality reduction through Kriging-KL and SGS- KL resulted in high accuracy of model-simulated heads, with R2 values exceeding 0.80 and 0.98 respectively. Overall, the K-L transform efficiently reduces parameter dimensions without compromising model performance. SGS-KL showed greater robustness under varying parameters, indicating its suitability for complex groundwater systems. This study contributes to efficient groundwater model inversion and provides valuable insights into the characteristics of groundwater systems.
The Crucial Role of Geothermal Fluids in Reducing the Water and Carbon Footprints of Lithium Mining in Salt Flats Worldwide
Authors: Alam Mohammad Ayaz 
Published: February 2025

ABSTRACT
Thermal waters, which often have a high Li concentration, can influence the formation of Li-rich brines in the salt flats. Several studies suggest that geothermal activity accelerates the leaching of Li-rich volcanic rocks in the catchment areas of the closed basins, contributing to higher Li concentrations in brines. Considering that there is no salt flat in Chile or other parts of the world that does not have a present-day (active) or palaeo-geothermal system, there is a need for a holistic geoscientific study of the salt flats to investigate the association between lithium enrichment of brine in the salt flats and geothermal systems present in the host closed basins. The expected results of such studies in different salt flats will help understand the role of geothermal systems in forming economic Li deposits that could be selectively mined sustainably. This is because thermal waters can also concentrate Li in specific horizons, allowing for selective extraction with minimal impact on freshwater aquifers. This would be possible because conductive heating by underlying thermal water could induce circulation (convective overturn) of basin brines within hydrologically connected horizons. Accordingly, this geothermally induced brine circulation may develop a heterogeneous subsurface Li distribution, where thermal waters could be instrumental in forming Li-enriched horizons in subsurface brine. Deciphering and modeling the latter will form a strong and tangible basis for developing environmentfriendly methods for Li mining that will have negligible influence on the groundwater and wetland ecosystems using drilling technologies prevalent in the hydrocarbon industry for extracting particular sedimentary horizons. Further, geothermal systems present in the closed hydrologcal basins could aid in reducing the environmental footprint of Li mining by providing thermal energy for extraction processes and electricity generation using low-enthalpy binary power plants. Considering the focus on direct extraction of Li (DLE) in Chile and neighboring countries, it is necesary to integrate it with geothermal following holistic geoscientific studies involving geological, geochemical and geophysical investigations, validated by exploratory drilling. This will help mitigate environmental challenges associated with current DLE technologies by using geothermal water in the extraction process and expertise from the geothermal industry in brine recharge.

Published: February 2025

Objective: to conduct clinical and economic analysis of nosocomial pneumonia antibacterial therapy in a multidisciplinary hospital in Moscow.Material and methods. The medical records of patients admitted to Yudin City Clinical Hospital in Moscow in 2019–2021 were analyzed retrospectively. Pharmacoepidemiological analysis included the structure of prescriptions of antibacterial drugs (ABDs), features of empirical and etiotropic therapy, duration of using ABDa and other parameters. In total, 110 cases of severe nosocomial pneumonia caused by ESKAPE pathogens were selected for analysis. Direct medical costs and cost-effectiveness coefficients were calculated based on real world data.Results. It was established that nosocomial pneumonia is the most common complication among hospitalized patients in the intensive care unit (ICU). The etiology of nosocomial pneumonia was mostly presented by K. pneumoniae, A. Baumanii, and P. aeruginosa. The administered ABDs included 31 international nonproprietary names of the group J01 Systemic antibacterial drugs. The direct medical costs of empirical antibacterial therapy averaged for 9367 rubles (2118 rubles [1462; 3525]). Comparative cost-effectiveness analysis was performed based on surrogate and endpoints. It was found that direct medical costs associated with ESKAPE pathogens spend about 70% of the budget of established tariff to pay for medical care of the compulsory health insurance program for the patient's stay in the ICU.Conclusion. Antibacterial therapy costs for nosocomial pneumonia significantly increase the total cost of a patient's hospital stay. Сlinical and economic assessment of drug use help optimize therapy costs and develop a hospital formulary of antimicrobial drugs.

HighlightsIn the modern literature, the algorithms for managing patients with CKD and ACS are not fully covered. However, approximately one in three ACS patients has CKD. To date, the frequency of using radial arterial access and intravascular imaging in patients with ACS and CKD in clinical practice is increasing, which significantly improves outcomes. However, many topics related to these issues remain poorly understood, so it is necessary to conduct specialized studies among all stages of CKD, taking into account eGFR, and the severity of albuminuria. AbstractThe number of patients suffering from chronic kidney disease (CKD) is growing progressively, in half of the cases they die from cardiovascular diseases (CVD) before they reach the terminal stage of renal failure. Patients with CKD belong to a special group of the population when considering ACS therapy. CKD complicates diagnosis, risk stratification, pharmacological therapy, invasive treatment, and ACS outcomes. The purpose of the review is to analyze the domestic and foreign literature on the management of ACS in patients with CKD, as well as to offer practical recommendations for practitioners and identify current knowledge gaps that require further research. ACS makes a significant contribution to the morbidity and mortality of patients with CKD, which makes it extremely relevant to study the features of ACS management in this group of patients. It is not uncommon for patients and clinicians to reject scientifically based diagnostic and therapeutic methods due to concerns about worsening renal failure. Although overcoming this phenomenon partly depends on following the recommendations, a complete solution to the problem will equally depend on a proper assessment of the risks, pharmacological and invasive factors characteristic of patients with CKD. To date, the frequency of using radial arterial access and intravascular imaging in patients with ACS and CKD in clinical practice is increasing, which significantly improves outcomes. Nevertheless, a large number of knowledge gaps remain, so it is necessary to conduct specialized studies among all stages of CKD, not only taking into account eGFR, but also the severity of albuminuria. It is important to note that this will require better representation of CKD patients in randomized trials.
