Consensus statements from the International Society for Heart and Lung Transplantation consensus conference: Heart failure-related cardiogenic shock.

The last decade has brought tremendous interest in the problem of cardiogenic shock. However, the mortality rate of this syndrome approaches 50%, and other than prompt myocardial revascularization, there have been no treatments proven to improve the survival of these patients. The bulk of studies have been in patients with acute myocardial infarction, and there is little evidence to guide the clinician in those patients with heart failure cardiogenic shock (HF-CS).

Endomyocardiofibrosis in the Americas Collaborative Study: The EMF-SIAC Registry.

Endomyocardiofibrosis (EMF) is a restrictive cardiomyopathy characterized by subendocardial fibrosis due to eosinophilic myocardial infiltration. EMF may commonly present with heart failure (HF) or atrial fibrillation (AF). Immunosuppression can be effective in early stages, but not in the chronic phase.

Evidence of Continued CD4+ and CD8+ T Cell Activity After SARS-COV-2 Clearance in a Late COVID-19 Pneumonia Heart Transplant Patient.

We have studied an unvaccinated heart transplant 64-year-old patient admitted for low-grade fever, dry cough, general malaise, and bilateral interstitial infiltrates, after two months of a diagnosis of coronavirus disease 2019 (COVID-19) bilateral pneumonia. A bronchoalveolar lavage and transbronchial biopsy were performed. Bacterial, mycotic and viral infections were ruled out including repeated reverse transcription polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Mercury concentrations, biomagnification and isotopic discrimination factors in two seabird species from the Humboldt Current ecosystem.

Assessing mercury (Hg) biomagnification requires the description of prey-predator relationships, for each species and ecosystem, usually based on carbon and nitrogen isotope analyses. Here, we analyzed two seabirds from the Humboldt Current ecosystem, the Guanay cormorant (Phalacrocorax bougainvillii) and the Peruvian booby (Sula variegata), as well as their main prey, the Peruvian anchovy (Engraulis ringens). We reported Hg concentrations, Hg biomagnification (BMF) and isotopic discrimination factors (ΔC and ΔN) in seabird whole blood.
