Percutaneous large-bore axillary access is a safe alternative to surgical approach: A systematic review.

OBJECTIVES: To systematically review relevant literature regarding cardiovascular outcomes of large-bore axillary arterial access via percutaneous and surgical approaches. BACKGROUND: In patients with severe peripheral arterial disease (PAD) undergoing cardiac interventions, large-bore femoral access may be prohibitive. The axillary artery provides an alternative vascular access for transcatheter aortic valve replacement (TAVR) or mechanical circulatory support. There have been limited comparisons of percutaneous transaxillary (pTAX) approach with the more traditional surgical transaxillary (sTAX) approach. METHODS: Pubmed and Medline databases were queried through January 2019 for studies describing pTAX or sTAX approaches with TAVR or Impella insertion. Primary outcomes were access-related mortality, 30-day mortality, stroke, major vascular complications, and major bleeding. RESULTS: One hundred and fifty five studies were reviewed, with additional unpublished data from 1 institution. Twenty-two studies met the inclusion criteria. Patient data was heterogeneous, with 69% TAVR and 31% Impella use in the pTAX group, and 96% TAVR and 4% Impella use in the sTAX group. There was more cardiogenic shock in the pTAX group. When compared to surgical approach, the percutaneous approach had similar 30-day mortality for TAVR (5.6% vs 4.6%, OR non-significant) and Impella (43.4% vs 38.6%, OR non-significant), similar stroke rates (4.3% vs 4.2%, OR non-significant), similar major vascular complications (2.8% vs 2.3%, OR non-significant) and less major bleeding (2.7% vs 17.9%, OR significant). CONCLUSIONS: Data suggests large-bore pTAX access has similar 30-day mortality, stroke rates, and major vascular complications as sTAX access, with less major bleeding. Additional studies are needed to validate results.

Clinical and procedural characteristics of persons living with HIV presenting with acute coronary syndrome.

OBJECTIVES: Persons living with HIV (PLWH) are at greater risk for acute coronary syndrome (ACS). Practice patterns of ACS management by HIV serostatus are unknown. We examined the presentation and management of ACS in PLWH. DESIGN: Retrospective case-control study. METHODS: We included 86 PLWH and 263 sex-matched and race-matched HIV-negative controls hospitalized with ACS between 2004 and 2013. We performed multivariable conditional logistic regression to determine the associations between HIV serostatus and ACS type and management. RESULTS: Both groups were predominantly of black race and male sex. PLWH were significantly younger (53 vs. 60 years) and more likely to smoke (48 vs. 31%). Among PLWH, 30% had CD4 cell count less than 200 cells/µl and 58% had undetectable HIV RNA. PLWH had more single-vessel disease and a higher median Gensini score among those with single-vessel disease (32 vs. 4.25) than controls. HIV serostatus was positively associated with ST-elevation myocardial infarction (STEMI) [adjusted odds ratio (aOR) (95% confidence interval (CI)):5.05 (1.82-14.02)], and any revascularization procedure after ACS [aOR (95% CI): 2.90 (1.01-8.39)] and negatively associated with non-STEMI [aOR (95% CI): 0.33 (0.14-0.79)] presentation. PLWH who underwent stent placement had a higher likelihood of bare metal stent placement compared with controls [70 vs. 15%, aOR (95% CI): 5.94 (1.33-26.55)]. Among PLWH, ACS characteristics were not significantly associated with CD4 cell count, HIV RNA, or antiretroviral therapy. CONCLUSION: PLWH hospitalized with ACS were more likely to have severe single-vessel disease, present with STEMI rather than non-STEMI, and undergo revascularization, and less likely to have a drug-eluting stent placed than matched HIV-negative controls, suggesting that coronary plaque morphology and/or distribution is different with HIV infection and warrants further investigation.

Natural Approaches in Diabetes Management: A Review of Diet, Exercise, and Natural Products.

Diabetes mellitus (DM) is a highly prevalent condition that causes significant morbidity and mortality in the United States and worldwide. Conventional therapies include lifestyle modification, oral pharmacological agents, and subcutaneous insulin. Emerging data suggest that natural approaches to the treatment of DM may help supplement current therapies for further glycemic control. Herein, we review the evidence of several natural modalities for DM treatment. We describe the pathophysiology of diabetes and its complications, provide an overview of current pharmacologic treatments, and finally, discuss natural approaches to diabetes management. Specifically, we will describe on the utility of diet, physical activity, and common natural products in the treatment of DM and focus on recent, high-quality studies. Adverse effects and potential interactions of each therapy will be highlighted where applicable.
