Association of breast arterial calcification with stroke and angiographically proven coronary artery disease: a meta-analysis
Objective: We conducted a meta-analysis of the current literature to deduce the strength of association between breast arterial calcification (BAC) and coronary artery disease (CAD) and/or stroke.
Methods: PubMed, Google Scholar, ClinicalTrials.gov, and Ovid were searched for English-language literature up to August 2013 using the terms “breast arterial calcification,” “breast vascular calcification,” “coronary artery disease,” “coronary heart disease,” “cardiovascular disease,” “abnormal coronary angiography,” and “stroke.” A hand search of the reference lists of key articles was performed to s...

Active testing search for point cloud matching.
We present a general approach for solving the point-cloud matching problem for the case of mildly nonlinear transformations. Our method quickly finds a coarse approximation of the solution by exploring a reduced set of partial matches using an approach to which we refer to as Active Testing Search (ATS). We apply the method to registration of graph structures by branching point matching. It is based solely on the geometric position of the points, no additional information is used nor the knowledge of an initial alignment. In the second stage, we use dynamic programming to refine the solution. We tested our algorithm on ang...

Stress echocardiography for the diagnosis of coronary artery disease: an evidence-based analysis.
The objective of the analysis is to determine the diagnostic accuracy of stress echocardiography (ECHO) in the diagnosis of patients with suspected coronary artery disease (CAD) compared to coronary angiography (CA). STRESS ECHOCARDIOGRAPHY: Stress ECHO is a non-invasive technology that images the heart using ultrasound. It is one of the most commonly employed imaging techniques for investigating a variety of cardiac abnormalities in both community and hospital settings. A complete ECHO exam includes M-mode, 2-dimensional (2-D) images and Doppler imaging. In order to diagnosis CAD and assess whether myocardial ischemia is ...

Finite Element Analysis in Asymptomatic, Symptomatic, and Ruptured Abdominal Aortic Aneurysms: In Search of New Rupture Risk Predictors.
CONCLUSIONS: From different FEA derived parameters, PWRI distinguishes most precisely between asymptomatic and symptomatic AAA. If elevated, this value may represent a negative prognostic factor for asymptomatic AAAs.

Cerebral mycotic aneurysm as a consequence of infective endocarditis: A literature review
Conclusion The CMAs are risky due to their potential consequences of cerebral hernia and aneurysmal rupture. The treatment of this entity is always challenging as it is difficult to determine the timing of the cerebral and cardiac operations concerning the necessity of heparinization in cardiac surgery. Sufficient antibiotics have to be used in IE patients in order to prevent from the potential consequence like CMAs. The choices of treatment for CMAs depend on the conditions of CMAs. They are curable to either conservative, endovascular or surgical management in selected patients. At least a 2-week interval between clippin...

Indocyanine Green Angiography in Breast Reconstruction: Utility, Limitations, and Search for Standardization
Conclusions:
ICGA can reduce postoperative tissue loss and aid in intraoperative flap design and inset. Despite the benefits of ICGA, its technical use and interpretation have yet to be standardized, limiting its widespread acceptance.

OCTA Biomarker Search in Patients with nAMD: Influence of Retinal Fluid on Time-Dependent Biomarker Response
CONCLUSIONS: OCTA-based parameters VA, TVL, TNJ, and MNVarea show a strong response to anti-VEGF therapy over time, independent of the presence of IRF, SRF or RT. We conclude that the above listed OCTA parameters could contribute to our understanding of MNV biology and to guide individualized treatment in the future.TRIAL REGISTRY: The authors confirm that all ongoing and related trials are registered.

Local intramuscular transplantation of autologous bone marrow mononuclear cells for critical lower limb ischaemia
CONCLUSIONS: We identified a small number of studies that met our inclusion criteria, and these differed in the controls they used and how they measured important outcomes. Limited data from these trials provide very low- to low-certainty evidence, and we are unable to draw conclusions to support the use of local intramuscular transplantation of BMMNC for improving clinical outcomes in people with CLI. Evidence from larger RCTs is needed in order to provide adequate statistical power to assess the role of this procedure.PMID:35802393 | PMC:PMC9266992 | DOI:10.1002/14651858.CD008347.pub4

Thoracic outlet syndrome: a review for the primary care provider
CONCLUSIONS: The most common form of TOS is neurogenic. The most common symptoms are pain and paresthesias of the head, neck, and upper extremities. Diagnosis of nTOS is clinical, and the best screening test is the ULTT. There is no conclusive evidence that any one treatment method is more effective for nTOS, given limitations in the published data. Surgical decompression remains the treatment of choice for vascular forms of TOS.PMID:36018621 | DOI:10.1515/jom-2021-0276
