The impact of diet on cardiovascular disease has become an increasingly relevant topic as ongoing epidemiological evidence continues to demonstrate clear associations with disease burden and mortality. Certain diets, such as those high in sodium and saturated fat, are associated with cardiovascular disease states, while other diets can be cardioprotective. However, there is limited knowledge on how the micro- and macronutrients within such cardioprotective diets afford their benefits. One such micronutrient is the catechin class, which are naturally occurring compounds in plant foods, such as teas, cocoa, wine, pears, and apples. Recent evidence reveals that catechins may be a key mediator in cardiovascular health via mechanisms of blood pressure reduction, flow-mediated vasodilation, and atherosclerosis attenuation. This review evaluates the current literature on the interplay between catechins and cardiovascular disease, which may have important implications for nutrition counseling and pharmaceutical drug development.

This study evaluated the safety of 3-level anterior cervical diskectomy and fusion (ACDF) with ultra-low-dose recombinant bone morphogenetic protein-2 (rhBMP-2). Thirty-seven consecutive patients with cervical spondylotic myelopathy who were treated with 3-level ACDF and rhBMP-2 were evaluated. Complications such as airway or cervical swelling or hematoma were not observed. The rate of dysphagia was no different at 1, 2, and 6 months postoperatively compared with reports in the literature without rhBMP-2. There were significant improvements in VAS neck/arm pain, Oswestry Neck Disability Index, and cervical lordosis. The use of ultra-low-dose rhBMP-2 for 3-level ACDF may be efficacious for surgically addressing 3-level spondylotic myelopathy.

Transcatheter PFO closure has a high success rate, but a moderate residual shunt occurs in about 10% of cases. The observed incidence of residual shunting after PFO closure is significantly larger with the 30-mm Helex device. © 2014 Wiley Periodicals, Inc.

The purpose of this study was to compare the outcomes of instrumented versus noninstrumented (decompression) surgical treatment of vertebral osteomyelitis. The study population included 104 patients with spinal osteomyelitis who were treated at the authors' institution between 2004 and 2012. This included 62 men and 42 women who underwent either instrumented (n=57) or noninstrumented (n=47) surgery. Mean patient age was 59 years, and mean follow-up was 38 months (range, 12-78 months). Specifically, the following criteria were assessed: mortality rates, infection clearance rates, clinical outcomes measured by Oswestry Disability Index (ODI), mean length of stay, and baseline differences between the 2 cohorts. Although patients in the instrumented cohort had more instability, more neurologic symptoms, and larger volume infection, they had similar clearance of infection (54% vs 42.5%; odds ratio [OR], 1.55; 95% confidence interval [CI], 0.61-3.9; P=.35), mortality rate (9% vs 17%; OR, 0.47; 95% CI, 0.14-1.54; P=.21), and ODI scores (40 vs 45 points; P=.32) compared with patients in the noninstrumented group. However, mean length of stay (19 vs 13 days; P=.02) was significantly higher for patients in the instrumented group. Even in more severe cases of vertebral osteomyelitis, instrumentation resulted in comparable outcomes to decompression. [Orthopedics. 2016; 39(3):e504-e508.].

Objective: The objective of this qualitative review is to summarize the pathophysiological and clinical data behind the clinical entity of left internal mammary artery (LIMA) side branch coronary steal as well as the potential diagnostic and therapeutic modalities available. Background: The presence of persistent unligated LIMA side branches following coronary artery bypass grafting has previously been associated with stable angina and acute coronary syndromes. However, despite numerous attempts to objectively demonstrate a coronary steal phenomenon, the pathophysiology of LIMA side branch flow diversion remains elusive and the clinical utility of intervention is not well elucidated. Methods: A review of literature and available data including case reports, case series, and investigational studies was performed. Results: Therapeutic closure of LIMA side branches has been reported in at least 44 patients and in at least 31 publications since 1990 and is associated with an 87.5% rate of freedom from angina amongst technically successful initial interventions. In all patients with pre-and post-stress testing, intervention was associated with an improvement and/or resolution of previously observed reversible ischemia. Conclusions: LIMA side branch coronary steal should remain an ongoing consideration in symptomatic patients with large unligated side branches on angiography, particularly when there is clear evidence of reversible ischemic on perfusion imaging.
