Observational Study
HIV, vascular surgery and cardiovascular outcomes: a South African cohort study.
Risk factors for peri-operative cardiac morbidity are poorly described in HIV-positive patients. This prospective observational study describes cardiovascular risk factors in a cohort of vascular surgical patients of known HIV status. We recruited 225 patients with 73 (32%) being HIV-positive. ⋯ HIV-positive and -negative patients had similar outcomes in: 30-day mortality (p = 0.78); three-day postoperative troponin leak (p = 0.66); and a composite outcome of mortality and troponin release (p = 0.69). We conclude that although HIV-positive patients have fewer cardiovascular risk factors, they have similar peri-operative major adverse cardiac events to HIV-negative patients. Research should focus on why this is the case, and if alternative clinical risk predictors can be developed for HIV patients.

Critical Care Case Report PostersSESSION TYPE: Case Report PosterPRESENTED ON: Sunday, March 23, 2014 at 01:15 PM - 02:15 PMINTRODUCTION: TTP was once recognized for its classic pentad features of fever, thrombocytopenia, microangiopathic hemolytic anemia, neurologic dysfunction and renal impairment. However TTP may present with atypical features and the diagnosis may be unrecognized. ⋯ The following authors have nothing to disclose: Ma.

We studied the safety of use of acute reperfusion therapies in patients with stroke- on- awakening using a computed tomographic angiography (Cta) based large vessel occlusion-good scan paradigm in clinical routine. ⋯ When carefully selected using Ct –Cta, by a good scan (aSpeCtS > 7) occlusion paradigm, acute reperfusion therapies in patients with stroke-on-awakening can be performed safely in clinical routine.

AsthmaSESSION TYPE: Slide PresentationsPRESENTED ON: Saturday, March 22, 2014 at 12:15 PM - 01:15 PMPURPOSE: Asthma is a heterogenous disease with distinct clinical phenotypes, including the exacerbation-prone phenotype. This subset of patients contributes to disproportionately high morbidity, mortality and healthcare utilization among all asthma patients. We aimed to investigate the factors that are associated with frequent asthma exacerbations in patients with severe asthma. ⋯ The following authors have nothing to disclose: Jessica Tan, Mariko Koh, Anthony Yii, Adrian ChanNo Product/Research Disclosure Information.

Symptoms of Respiratory Disease PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: Studies of military personnel deployed to Operations Iraqi Freedom and Enduring Freedom have suggested an increase in chronic lung disease due to environmental exposures. Findings are based primarily on increased respiratory symptoms and retrospective data. Our previous study (STAMPEDE I) did not identify any acute interstitial or inflammatory process. The study objective was to complete a comprehensive evaluation of active duty military with deployment-related pulmonary symptoms and identify etiology of symptoms. ⋯ Michael Morris: Consultant fee, speaker bureau, advisory committee, etc.: Speaker Bureau for Spiriva with Pfizer/Boehringer/Ingelheim The following authors have nothing to disclose: Andrew Skabelund, Georgette Haislip, Pedro LuceroNo Product/Research Disclosure Information.
