Geriatric co-management and interdisciplinary transitional care reduced hospital readmissions in frail older patients in Argentina: results from a randomized controlled trial.

Background: Hospitalization is a moment of extreme vulnerability for frail older adults. There is scarce evidence on the effectiveness of geriatric co-management or transitional care interventions in Latin America.

Aims: To assess whether geriatric co-management combined with an interdisciplinary transitional care intervention could reduce 30-day hospital readmission rate compared to usual care in hospitalized frail older patients in a tertiary hospital in Argentina.

[Acute cardiovascular beriberi (shoshin-beriberi)].

Beriberi (BB), thiamine deficiency, has been described in the Asian literature in the 17th century and is characterized by peripheral neuropathy and muscle weakness, also called "dry" beriberi (BB) to differentiate it from "wet" BB, with essentially cardiovascular manifestations. Wet can be either "classic" wet BB in which signs and symptoms of right-sided heart failure with normal or high cardiac output are the presenting features or the "shoshin" BB variant with severe biventricular failure and metabolic acidosis, which must be treated early to prevent the rapid development of low cardiac output failure and sudden death. In this case, we report a 58 year old alcoholic woman who developed dyspnea, oliguria, edema, cardiac failure with high output, metabolic acidosis, renal tubular dysfunction and serum lactate level of 5.
