Clinical Outcomes of Thoracic Cancer Patients Requiring ICU Admission: A 10-Yea...

IntroductionLung cancer is the most common solid malignancy requiring intensive care unit (ICU) admission, but ICU admission for cancer patients is often denied, being the second most common reason for refusal. This study aimed to evaluate the outcomes of thoracic cancer patients admitted to the ICU and understand the characteristics that may affect these outcomes. MethodsThis retrospective cohort study analyze...

Integrated assessment of environmental risk in AMD-affected mine waste: mineral...

The long-term environmental legacy of mining in sulfide-rich regions remains a critical concern due to the persistent generation of acid mine drainage (AMD) and the mobilization of potentially toxic elements (PTEs). This study presents a comprehensive, site-specific assessment of mine waste from two contrasting geochemical zones, Nuestra Señora del Carmen (NSC) and Volta Falsa (VF), within the historically unde...

Copiapite group: occurrence and properties in mining contamination scenarios

ABSTRACT: The copiapite group shows a wide range of chemical compositions, allowing the identification of several mineral phases (e.g., aluminocopiapite and magnesiocopiapite). These minerals, typically observed in mining environments, are formed from evaporation and acid mine drainage (AMD) precipitation. In these areas, the copiapite has been studied to comprehend its ability to store some potentially toxic e...

From waste to resources: UAV monitoring of abandoned mine tailings and critical...

Acid mine drainage and waste dispersion in legacy mining sites: an integrated a...

Abandoned mines pose environmental risks due to the accumulation of sulfide-rich waste, which generates acid mine drainage and produces fine-grained, unconsolidated materials that, when deposited on steep slopes, accelerate erosion and contaminant transport. This study assesses the environmental impact of the Trimpancho mining complex by integrating UAV-based photogrammetry, water analysis, and mine waste chara...

A data-driven high-accuracy modelling of acidity behavior in heavily contaminat...

Accurate estimation of water acidity is essential for characterizing acid mine drainage (AMD) and designing effective remediation strategies. However, conventional approaches, including titration and empirical estimation methods based on iron speciation, often fail to account for site-specific geochemical complexity. This study introduces a high-accuracy, site-specific empirical model for predicting acidity in ...

The relevance of metallic species for monitoring acidity in mine waters: statis...

[Excerpt] Acid mine drainage (AMD) challenges the global mining industry due to its severe environmental impact on aquatic ecosystems, water resources, and soils. Areas affected by AMD are typically characterized by high acidity, low pH (< 3), and elevated concentrations of sulfate and metals (Fe, Al, Mn, and others). Monitoring and predicting water acidity in AMD systems is critical for assessing environmental...

Metastatic Non-Small Cell Lung Carcinoma treated with immunotherapy+ chemothera...

Assessment of response to systemic therapy can be challenging in mNSCLC, especially with immunotherapy, due to the possibility of atypical response patterns. We report a case of metastatic lung adenocarcinoma under immunotherapy and chemotherapy with an apparent response dissociated in a pulmonary nodule, whose biopsy of the non-responsive lesion revealed a histological diagnosis different from the primary tumo...

The role of the iron oxyhydroxides and efflorescent sulfates in remediation by ...

[Excerpt] Acid mine drainage (AMD) is a common problem associated with the weathering of metal sulfide wastes in abandoned mining areas, which can be rich in toxic metals and metalloids. The formation of secondary mineral phases such as iron oxyhydroxides, oxyhydroxysulfates, and efflorescent sulfates may be a natural attenuation process in mining soils because these minerals can scavenge potentially toxic elem...
