Cardiogenic Shock Secondary to Acute Mitral Regurgitation With Nonischemic Etiology Successfully Stabilized by Transcatheter Intervention.

• Echocardiography is essential in diagnosing cardiogenic shock secondary to acute MR. • TMVEER can stabilize these patients who present as prohibitive risks for surgery. • Careful monitoring is warranted after TMVEER.

A Case of Sarcoidosis Mimicking Lymphoma Confounded by Cognitive Decline.

Sarcoidosis is a disease with an unknown cause that affects multiple organ systems and has a varied clinical presentation. Often, its symptomatology mimics other disease processes, such as lymphoma, tuberculosis, and amyloidosis. The reticuloendothelial involvement and typical B symptoms of weight loss, fatigue, night sweats, and lymphadenopathy can make sarcoidosis often easily confused with lymphoma.

Quantification of shared air: a social and environmental determinant of airborne disease transmission.

Background: Tuberculosis is endemic in Cape Town, South Africa where a majority of the population become tuberculosis infected before adulthood. While social contact patterns impacting tuberculosis and other respiratory disease spread have been studied, the environmental determinants driving airborne transmission have not been quantified.

Methods: Indoor carbon dioxide levels above outdoor levels reflect the balance of exhaled breath by room occupants and ventilation.

Shared air: a renewed focus on ventilation for the prevention of tuberculosis transmission.

Background: Despite an improvement in the overall TB cure rate from 40-74% between 1995 and 2011, TB incidence in South Africa continues to increase. The epidemic is notably disquieting in schools because the vulnerable population is compelled to be present. Older learners (age 15-19) are at particular risk given a smear-positive rate of 427 per 100,000 per year and the significant amount of time they spend indoors.
