Potential geographic displacement of Chagas disease vectors under climate change. [PDF]

Med Vet Entomol
As a result of modelling the potential distribution of 55 triatomine species in the Neotropical region, with climate change projected for up to 2050, we found no significant changes. With climate change projected for up to 2080 in the Neotropical region, we see a significant potential for the migration of 55 species of triatomines towards the Amazon ...

COVID‐19 pandemic impact on blood donations and discards from screening tests for transfusion‐transmitted infections in a Brazil Brazilian metropolitan area

Transfusion Medicine, EarlyView.
Abstract Background The COVID‐19 pandemic posed a worldwide challenge for blood services. We aimed to evaluate the impact of the COVID‐19 pandemic on blood donations and blood discards resulting from screening tests for transfused‐transmitted infections (TTIs) in a Brazilian metropolitan.

How do I interpret transfusion transmissible infectious disease testing in a low‐risk donor population?

Transfusion, EarlyView.
Abstract Background Blood donors represent a unique population. Pre‐donation screening questions, donor self‐deferral, and temporary deferral and re‐testing of repeat reactive donors result in lower prevalence of infectious disease compared to the general population.

Assessment of Leishmania exposure in blood donors from a non‐endemic urban area: A study in São Paulo

Vox Sanguinis, EarlyView.
Abstract Background and Objectives According to the World Health Organization, more than 1 billion people are at risk of leishmaniasis in over 89 countries. Environmental changes such as deforestation, urban expansion and climate change facilitate the spread of sand fly vectors and reservoirs, increasing disease transmission.

Exercise‐induced effects on atherogenesis and tryptophan catabolism via the kynurenine pathway in an HIV‐associated atherosclerosis mouse model

Experimental Physiology, EarlyView.
Abstract A mouse model of HIV‐associated atherosclerosis (Tg26+/−ApoE−/−) exhibited increased plaque area compared with the ApoE−/− mouse, linked to elevated indoleamine 2,3‐dioxygenase (IDO) activity. IDO catalyses the conversion of tryptophan (TRP) into kynurenine (KYN), measured by the KYN‐to‐TRP ratio.

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

Experimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...

Deep Vein Thrombosis in Critically Ill Patients With COVID‐19 Pneumonia

Journal of Ultrasound in Medicine, Volume 45, Issue 1, Page 155-170, January 2026.
Objectives The risk of major venous thromboembolism (VTE) among patients with COVID‐19 is high but varies with disease severity. Estimate the incidence of lower extremity deep venous thrombosis (DVT) in critically ill hospitalized patients with COVID‐19, validate the Wells score for DVT diagnosis, and determine patients' prognosis.

Bufalin‐Induced Epithelial‐to‐Mesenchymal Transition in Kidney Epithelial Cells

Cell Biology International, Volume 49, Issue 12, Page 1764-1786, December 2025.
ABSTRACT The kidney plays a central role in fluid, electrolyte, and blood pressure regulation, processes tightly coupled to Na⁺/K⁺‐ATPase activity. Beyond its canonical transport function, Na⁺/K⁺‐ATPase also acts as a signaling receptor for cardiotonic steroids (CTSs) such as bufalin, which have been implicated in fibrosis and epithelial‐to‐mesenchymal

Minimally Invasive Repair of Left Ventricular Aneurysm After Esophagectomy With Retrosternal Gastric Conduit: A Case Report

Clinical Case Reports, Volume 13, Issue 12, December 2025.
Preoperative CT and 3D reconstruction demonstrating an inferior left ventricular aneurysm in a patient with a retrosternal gastric conduit, highlighting the rationale for choosing a left mini‐thoracotomy approach. ABSTRACT In patients with prior esophagectomy and retrosternal gastric conduit, conventional sternotomy may be hazardous.
