Article Synopsis
  • This study explores multi-element compound-specific isotope analysis (CSIA) to assess the biodegradation of 2,3-dichloroaniline (2,3-DCA), a significant industrial chemical, during controlled laboratory experiments.* -
  • Findings reveal negligible carbon and hydrogen isotope fractionation but notable inverse nitrogen isotope fractionation during the aerobic biodegradation, suggesting that the reaction’s initial enzymatic step might limit the process.* -
  • The research indicates that using nitrogen isotope signatures can help estimate biodegradation levels in contaminated sites, with potential rates reaching 80-90%, showcasing multi-element CSIA as a promising method for studying environmental chemical transformations.*

Precision oncology treatments are being applied more commonly in breast and gynecological oncology through the implementation of Molecular Tumor Boards (MTBs), but real-world clinical outcome data remain limited. A retrospective analysis was conducted in patients with breast cancer (BC) and gynecological malignancies referred to our center's MTB from 2018 to 2023. The analysis covered patient characteristics, next-generation sequencing (NGS) results, MTB recommendations, therapy received, and clinical outcomes.

Precision oncology is a field of personalized medicine in which tumor biology forms the basis for tailored treatments. The preferred approach currently applied in clinical practice is based on the concept of malignant tumors as genetic diseases that are caused by mutations in oncogenes and tumor suppressors. On the one hand, these can be targeted by molecular drugs, while on the other hand, next-generation sequencing allows for comprehensive analysis of all relevant aberrations, thus enabling the matching of appropriate treatments across entities based on molecular information.

Pediatric COVID-19 vaccination is effective in preventing COVID-19-related hospitalization, but duration of protection of the original monovalent vaccine during SARS-CoV-2 Omicron predominance merits evaluation, particularly given low coverage with updated COVID-19 vaccines. During December 19, 2021-October 29, 2023, the Overcoming COVID-19 Network evaluated vaccine effectiveness (VE) of ≥2 original monovalent COVID-19 mRNA vaccine doses against COVID-19-related hospitalization and critical illness among U.S.

A lack of regular access to clean and safe water and sanitation is a persistent problem in many parts of the world. Most water insecurity studies focus on the world's less-industrialized and lower-income countries, where sanitation and water delivery infrastructure may never have existed. However, many individuals in higher-income countries experience invisible water insecurity, wherein specific households or individuals lack access to sanitation and clean water despite the relative wealth of their country.

Article Synopsis
  • A study investigated the impact of pre-existing immunocompromising conditions (ICCs) on pediatric patients with acute COVID-19 admitted to intensive care across 55 hospitals in the U.S.!
  • Out of 1,274 patients, 105 had ICCs, which were linked to higher in-hospital mortality (11.4% vs. 4.6%) and longer hospital stays, although initial disease severity was similar between those with and without ICCs.!
  • Despite the challenges, most patients with ICCs survived and left the hospital without new severe health issues, highlighting a positive aspect of the outcomes for these vulnerable patients.!

Plasmids play a major role in rapid adaptation of bacteria by facilitating horizontal transfer of diverse genes, most notably those conferring antibiotic resistance. While most plasmids that replicate in a broad range of bacteria also persist well in diverse hosts, there are exceptions that are poorly understood. We investigated why a broad-host range plasmid, pBP136, originally found in clinical isolates, quickly became extinct in laboratory populations.

Background: Proteinase-activated receptor 2 (PAR-2) is a G-protein coupled receptor associated with many inflammatory diseases, including asthma. We have shown an association between PAR-2 expression in peripheral blood monocytes and asthma severity as well as blood PAR-2 mRNA level and lung function. Since F2RL1 (the gene encoding PAR-2) polymorphisms affect PAR-2 expression, we hypothesize they may affect asthma severity.

Article Synopsis
  • A study analyzed the clinical characteristics and vaccination status of young children hospitalized for acute COVID-19 across 28 pediatric hospitals in the U.S. from September 2022 to May 2023.
  • Of the 597 children examined, only 4.5% had completed their primary COVID-19 vaccination series, while 7.0% had started but not completed it, with the majority being unvaccinated.
  • Most children admitted with severe COVID-19, including those requiring intensive care, were previously healthy and had not initiated vaccination, highlighting a concerning gap in immunization among vaccine-eligible young kids.

We show that red cell exchange (RCE) treats hyperleukocytosis in acute leukemia. RCE provided similar leukoreduction to standard therapeutic leukoreduction and could be superior in patients with severe anemia or monocytic leukemias or when requiring rapid treatment.

Background: Increased breast density augments breast cancer risk and reduces mammography sensitivity. Supplemental breast MRI screening can significantly increase cancer detection among women with dense breasts. However, few women undergo this exam, and screening is consistently lower among racially minoritized populations.

Personalized oncology according to current practice is primarily based on tumor biology, which is translated into genomic biomarkers. Mutations in oncogenes and tumor suppressor genes are targeted by rationally designed drugs and, conversely, are used to inform tailored treatment strategies. Faster and cheaper technologies for DNA sequencing enable genomic medicine in a clinical routine setting.

Article Synopsis
  • Compound specific isotope analysis (CSIA) is effective for tracking the degradation of contaminants in groundwater, but lacks methods for low concentration samples, particularly for H- and N-CSIA, which have higher detection limits compared to C-CSIA.
  • The study successfully uses polar organic chemical integrative samplers (POCIS) with C-, H-, and N-CSIA to analyze nitro- and amino-substituted chlorobenzenes, achieving isotopic equilibrium in lab tests after 30 days and showing comparable method quantification limits to solid phase extraction.

Background: The fast-changing labor market highlights the need for an in-depth understanding of occupational mobility impacted by technological change. However, we lack a multidimensional classification scheme that considers similarities of occupations comprehensively, which prevents us from predicting employment trends and mobility across occupations. This study fills the gap by examining employment trends based on similarities between occupations.

The circulating nucleocapsid (NCP) antigen of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is detectable in coronavirus disease-2019 (COVID-19) patients. To better understand the biology of disease severity, we investigated NCP clearance kinetics in hospitalized COVID-19 patients. Serum NCP was quantified using a commercial NCP-specific enzyme-linked immunoassay in hospitalized COVID-19 patients (n = 63) during their hospital stay.
