We present clinical and radiological findings in a case of collecting (Bellini) duct carcinoma (CDC). This is a rare and aggressive kidney cancer originating from the distal renal tubule. The patient underwent radical nephrectomy and the pathological report showed trabeculopapillary, partially solid adenocarcinoma infiltrating the renal capsule and sinus. Immunohistochemical, as well as mucinocarminic and PAS staining studies are necessary for diagnosis of CDC. Surprisingly, one year follow-up studies were negative for recurrent disease. Chromosomal findings are usually different from most often diagnosed clear cell renal cell cancers. Findings from the literature are briefly discussed.

Use of the oxygen reserve index/FiO as a non-invasive index to estimate venous admixture in anesthetized dogs.
Front Vet Sci

Department of Clinical Sciences, Ross University School of Veterinary Medicine, Basseterre, Saint Kitts and Nevis.
The oxygen reserve index (ORi) is a novel, non-invasive parameter that estimates arterial oxygen partial pressure (PaO) during hyperoxia when the fraction of inspired oxygen (FiO) is elevated. This study aimed to assess the utility of the ORi/FiO ratio as an index for quantifying F-shunt, serving as an estimate of venous admixture. Anesthetic records were reviewed from 44 dogs undergoing general anesthesia and requiring arterial catheterization.

Sepsis is one of the leading causes of mortality in hospital settings, and early diagnosis is a crucial challenge to improve clinical outcomes. Artificial intelligence (AI) is emerging as a valuable resource to address this challenge, with numerous investigations exploring its application to predict and diagnose sepsis early, as well as personalizing its treatment. Machine learning (ML) models are able to use clinical data collected from hospital Electronic Health Records or continuous monitoring to predict patients at risk of sepsis hours before the onset of symptoms.

Background: Kappa free light chains (KFLCs) are emerging as promising biomarkers for intrathecal B cell activity for diagnosing multiple sclerosis (MS) through cerebrospinal fluid (CSF) analysis. In this study, we evaluated the ability of KFLC formulas to identify the presence of MS and their agreement with the 'gold standard' of CSF IgG oligoclonal bands (OCBs).
Methods: A total of 233 patients were included in this study: 149, comprising 43 males and 106 females, had MS, and the remainder, 40 males and 44 females, had other neurological diseases (ONDs).
Performance and stability analysis of all-perovskite tandem photovoltaics in light-driven electrochemical water splitting.

All-perovskite tandem photovoltaics are a potentially cost-effective technology to power chemical fuel production, such as green hydrogen. However, their application is limited by deficits in open-circuit voltage and, more challengingly, poor operational stability of the photovoltaic cell. Here we report a laboratory-scale solar-assisted water-splitting system using an electrochemical flow cell and an all-perovskite tandem solar cell.

Background: Cell-free hemoglobin (CFH) and free heme are potent mediators of endotheliopathy and organ injury in sepsis, but their roles in other hemolytic pathologies are not well-defined. A prime example is trauma where early hemolysis may initiate damage and predict outcome. Here, we investigated the presence of plasma CFH, heme, and their major scavengers after traumatic injury.
