Associations of Left Atrial Volume Index to Left Ventricular Ejection Fraction Ratio with Clinical Outcomes in Transthyretin Cardiac Amyloidosis.

Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) affects all cardiac chambers to cause left ventricular (LV) deformation as well as left atrial (LA) remodeling and functional impairment. We investigated the associations of the LA volume index (LAVI):LV ejection fraction (LVEF) ratio with the increased risk of death, heart transplant, or LV assist device implantation (LVAD) in patients with ATTR-CM.

Methods: This was a retrospective cohort study involving 69 heart failure (HF) patients with ATTR-CM at an academic medical center between 1 November 2008 and 31 March 2024.

Successful treatment of painful chronic wounds with amniotic and umbilical cord tissue: A case series.

Patients with chronic wounds may experience persistent, debilitating pain that cannot be adequately managed with analgesics and that negatively impacts their quality of life. In this case series, three painful chronic and ischemic wounds that were caused by polyarteritis nodosa vasculitis ( = 1) and peripheral arterial disease (PAD) ( = 2) were successfully treated with cryopreserved umbilical cord tissue and/or amniotic membrane and umbilical cord particulate, resulting in notable reduction in pain within 7 days followed by expedited wound closure. No adverse events related to these tissue products were observed.

Actinobaculum schaalii causing urinary tract infections: report of four cases from Argentina.

Actinobaculum schaalii may be a more common urinary tract pathogen than previously described. Here we report four cases of A. schaalii UTIs and we also propose a simple identification scheme to be used in the conventional microbiology laboratory based on standard biochemical tests.
