Summary: This study aims to provide a rapid molecular-based protocol for detection and quantification of viable SARS-CoV-2 on surfaces, which helps researchers better understand the risk of contracting COVID-19 through contact with fomites and develop more efficient epidemiological measures. The study evaluates different methods to recover inactivated SARS-CoV-2 particles from surfaces and compares them with surrogates, showing efficient removal of PCR signals from inactivated SARS-CoV-2 suspensions.

Summary: Research on airborne exposure to SARS-CoV-2 in indoor environments, particularly in healthcare settings, is ongoing. Currently, there is no standardized or optimized method for bioaerosol sampling, leading to limitations in representing temporal and spatial variability of the virus in aerosols. Experimental models indicate that environmental samples with higher viral RNA amplification values may not necessarily have infectivity. Standardization of long-term monitoring and infectivity assessment for SARS-CoV-2 in the air is urgently needed.

Summary: Whole genome sequencing is the best tool to track virus evolution and variant spread, but its ability to analyze a large number of samples is still inferior to qPCR. Advanced qPCR methods are needed for epidemiological and clinical research to quickly and affordably identify emerging variants and collect data on their spread. This study designed a one-step RT-qPCR assay for multiplex detection of the Omicron lineage, which showed high sensitivity and specificity and was cross-validated by WGS.

Summary: The study investigated the detection of total and subgenomic RNA of SARS-CoV-2 in nasopharyngeal swab samples and their relationship to symptom duration. Results showed that subgenomic RNA levels declined linearly with total RNA levels, with a constant relationship over the duration of symptoms. This suggests that subgenomic RNA may not provide additional information on infectivity beyond what can be determined by total RNA copies.

Summary: Saliva is not suitable as a specimen alternative; both saline (0.45%) and guanidine hydrochloride are effective in virus detection; stability of SARS-CoV-2 in saline and guanidine hydrochloride at room temperature; reducing primer/probe concentration and thermocycling times increases testing capability without significant loss of performance.

Summary: Although SARS CoV-2 infection may not be as serious a threat as before, the increased transmissibility of the Omicron variant remains a challenge for health care systems. This study evaluates the performance of three SARS-CoV-2 diagnostic tests and finds that all have high specificity and sensitivity for detecting the virus. The LOD values for each test were determined and suggest that the reported outcomes should be based on internal validation rather than manufacturer's declarations.

Summary: This study aimed to investigate the presence of Staphylococcus aureus in wild ungulates and determine its relationship with clinical and food-chain settings. The results showed the existence of methicillin-resistant and phenotypically linezolid-resistant S. aureus in wild boar and red deer, indicating the occurrence of resistance in wildlife. Genotypic analysis revealed some clonal lineages that are also found in humans and livestock. Additionally, the study identified that land use, human disturbance, and host-related factors determine the occurrence of resistance.

Summary: Climate change is altering population habits, leading to water shortages, which require new water sources for less stringent applications like agriculture. In this study, different water sources were used to irrigate vegetables/fruits, revealing potential health risks from secondary-treated and chlorine-treated wastewater, and the potential of green wall-treated greywater as a safe option. The study demonstrated the need for further improvement in reclaimed water to eliminate the risk of foodborne diseases and protect human health.

While collaborations between statisticians and ecologists have always been important, expertise from computer scientists and engineers is now becoming increasingly necessary. This article discusses the current and potential future changes in animal abundance surveys, highlighting the decreasing importance of classical methods like distance sampling and capture-recapture, and the growing significance of camera surveys, acoustic surveys, spatial capture-recapture, and genetic methods. The impact of these changes on the work of statisticians in ecology is explored.

Summary: Ecological interactions between wildlife and cattle play a fundamental role in the transmission of bovine tuberculosis caused by Mycobacterium bovis. This study aimed to evaluate the patterns of wildlife-cattle interaction at a global level and identify the factors influencing these interactions. The results showed that direct interactions between wildlife and cattle were low, while indirect interactions were significantly higher. Increasing wildlife density was found to increase the risk of indirect interactions and potential transmission of tuberculosis to cattle. This study highlights the importance of considering indirect interactions in controlling and preventing tuberculosis transmission at the wildlife-livestock interface.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
