Syphilitic Coronary Artery Ostial Stenosis Resulting in Acute Myocardial Infarction Treated by Percutaneous Coronary Intervention
Marcelo A. Nakazone,Maurício N. Machado,Raphael B. Barbosa,Márcio A. Santos,Lilia N. Maia
Case Reports in Medicine , 2010, DOI: 10.1155/2010/830583
Abstract: Cardiovascular abnormalities are well-known manifestations of tertiary syphilis infections which although not frequent, are still causes of morbidity and mortality. A less common manifestation of syphilitic aortitis is coronary artery ostial narrowing related to aortic wall thickening. We report a case of a 46-year-old male admitted due to acute anterior ST elevation myocardial infarction submitted to primary percutaneous coronary intervention successfully. Coronary angiography showed a suboccluded ostial lesion of left main coronary artery. VDRL was titrated to 1/512. The patient was discharged with treatment including benzathine penicillin. Previous case reports of acute myocardial infarction in association with syphilitic coronary artery ostial stenosis have been reported, but the fact that the patient was treated by percutaneous coronary intervention is unique in this case.

Abstract: background: percutaneous coronary intervention (pci) has become one of the most commonly performed cardiac procedures in clinical practice. due to improvement in outcomes, reduced acute complication rates, the need to reduce costs and the limited availability of hospital beds, elective pci with same-day discharge has become an interesting option. methods: single-center registry with a retrospective evaluation of all patients undergoing elective pci who were discharged on the same day, from january 2009 to march 2012. the rates of major adverse cardiac events (death, myocardial infarction, target-vessel revascularization and stroke), in addition to stent thrombosis, vascular complications and re-hospitalization between hospital discharge and the first 30 days of follow-up were determined. results: sixty-nine patients were evaluated with mean age of 64.5 ± 11.2 years, most of them were male (82%), and 28% were diabetics. all patients had stable coronary artery disease and type a or b1 lesions (36% and 36% respectively). radial access was the most commonly used approach (89%), with 5 f introducer sheaths in 56% and 6 f in the remaining patients. procedure success was obtained in 98.5%. no clinical events were observed at the 30-day follow-up. conclusions: our results demonstrated that same-day discharge was safe for patients with low clinical and angiographic risk undergoing elective pci with no procedure-related complications.
The components of economic freedom, income and growth: an empirical analysis
Corbi, Raphael B.;
Estudos Econ?micos (S?o Paulo) , 2007, DOI: 10.1590/S0101-41612007000300003
Abstract: this paper seeks to bring a better understanding of the relationship between economic growth and the disaggregated factors which constitute the elements of economic freedom. the two main objectives of this paper are to: (1) based on the solow augmented growth model, test which of the elements of economic freedom demonstrate a statistically significant relationship to economic growth; and (2) establish which way the main causality direction between economic freedom and growth runs from. finally, we identify desirable directions for further research and policy implications.
Borrelia burgdorferi aggrecanase activity: more evidence for persistent infection in Lyme disease
Raphael B. Stricker
Frontiers in Cellular and Infection Microbiology , 2013, DOI: 10.3389/fcimb.2013.00040
Abstract: Lyme disease is the most common tickborne illness in the world today. A recent study describes for the first time an enzyme produced by the spirochetal agent of Lyme disease, Borrelia burgdorferi, that cleaves aggrecan, a proteoglycan found in joints and connective tissue. Discovery of the spirochetal aggrecanase raises many questions about the pathogenesis of Lyme arthritis and lends support to the concept of persistent B. burgdorferi infection in patients with chronic Lyme disease symptoms.
Artificial Night Lighting Reduces Firefly (Coleoptera: Lampyridae) Occurrence in Sorocaba, Brazil  [PDF]
Oskar Hagen, Raphael Machado Santos, Marcelo Nivert Schlindwein, Vadim Ravara Viviani
Advances in Entomology (AE) , 2015, DOI: 10.4236/ae.2015.31004
Abstract: Artificial night lighting is gaining attention as a new type of pollution; however, studies of its impacts are scarce. Fireflies provide good models to investigate its effects on nocturnal wildlife, since they depend on their bioluminescence for reproduction. This study investigated the impact of artificial illumination on firefly activity at the new campus of the Federal University of São Carlos (Sorocaba, Brazil). The flashing activity of different firefly species, especially Photinus sp1 (82% of all occurrences), was investigated during 3 years, before and after the installation of multi metal vapor spotlights. Quantitative and qualitative analysis, performed in transects at different distances from the artificial light sources, showed significant negative effects on Photinus sp1 occurrence. This study proposes fireflies as potential flagship species and bioindicators for artificial night lighting and for the first time quantifies its effects, providing subsidies for future conservationist legislations regarding photopollution.
The Infectious Diseases Society of America Lyme guidelines: a cautionary tale about the development of clinical practice guidelines

Abstract: 'Without health, there is no happiness'. Thomas Jefferson'The strong do what they can; the weak endure what they must'. ThucydidesWith the trend toward centralized medical decision making and evidence-based medicine, clinical practice guidelines are becoming a key factor in the practice of medicine and are increasingly relied upon by physicians seeking treatment guidance. However, when guidelines panels fail to conscientiously safeguard the integrity of the guideline development process, the quality of guidelines may be eroded and fall short of the primary goal of guidelines--namely improving patient outcomes [1]. The Connecticut Attorney General's antitrust investigation into the Lyme disease treatment guidelines development process of the Infectious Diseases Society of America (IDSA) underscores the importance of these problems and the need for guidelines reform [2].Guidelines have become a way to drive the medical standard of care that governs physician conduct. When inflexible guidelines are adhered to by insurers, government agencies, medical societies and hospitals, guidelines can essentially create a de facto regulatory scheme fraught with economic, legal, and patient care consequences. Accordingly, guidelines, particularly those formulated by medical societies that are considered dominant under antitrust laws, hold enormous influence over the practice of medicine, creating a situation that is ripe for abuse [3]. For example, third parties such as the insurance industry and pharmaceutical companies whose commercial interests may be affected by guidelines may seek to influence the guidelines development process through the use of 'key opinion leaders' (typically academic researchers) who serve on guidelines panels. The enormous influence of clinical practice guidelines also creates the potential for the guidelines of a dominant medical society to be used competitively against less influential medical societies.The primary goal of clinical practice guidelines i

Abstract: isease: the next decade Perspectives (20744) Total Article Views Authors: Raphael B Stricker, Lorraine Johnson Published Date January 2011 Volume 2011:4 Pages 1 - 9 DOI: http://dx.doi.org/10.2147/IDR.S15653 Raphael B Stricker, Lorraine Johnson International Lyme and Associated Diseases Society, Bethesda, MD, USA Abstract: Although Lyme disease remains a controversial illness, recent events have created an unprecedented opportunity to make progress against this serious tick-borne infection. Evidence presented during the legally mandated review of the restrictive Lyme guidelines of the Infectious Diseases Society of America (IDSA) has confirmed the potential for persistent infection with the Lyme spirochete, Borrelia burgdorferi, as well as the complicating role of tick-borne coinfections such as Babesia, Anaplasma, Ehrlichia, and Bartonella species associated with failure of short-course antibiotic therapy. Furthermore, renewed interest in the role of cell wall-deficient (CWD) forms in chronic bacterial infection and progress in understanding the molecular mechanisms of biofilms has focused attention on these processes in chronic Lyme disease. Recognition of the importance of CWD forms and biofilms in persistent B. burgdorferi infection should stimulate pharmaceutical research into new antimicrobial agents that target these mechanisms of chronic infection with the Lyme spirochete. Concurrent clinical implementation of proteomic screening offers a chance to correct significant deficiencies in Lyme testing. Advances in these areas have the potential to revolutionize the diagnosis and treatment of Lyme disease in the coming decade.

Non-symmetric discrete Toda systems from quad-graphs
Raphael Boll,Yuri B. Suris
Physics , 2009,
Abstract: For all non-symmetric discrete relativistic Toda type equations we establish a relation to 3D consistent systems of quad-equations. Unlike the more simple and better understood symmetric case, here the three coordinate planes of $\mathbb Z^3$ carry different equations. Our construction allows for an algorithmic derivation of the zero curvature representations and yields analogous results also for the continuous time case.
