An In Vitro Model of a Parallel-Plate Perfusion System to Study Bacterial Adherence to Graft Tissues
Published on: January 7, 2019
Summary
Updated guidelines for infective endocarditis prophylaxis in 2007 question previous recommendations. Prophylaxis is now focused on high-risk patients, acknowledging daily activities cause bacteremia.
Area of Science:
- Cardiology
- Infectious Diseases
- Dental Medicine
Background:
- The 2007 American Heart Association guidelines revised infective endocarditis prophylaxis recommendations.
- Emerging data questioned the efficacy of previous prophylaxis regimens.
- Bacteremia from daily activities (e.g., brushing teeth) is more common than from dental procedures.
Purpose of the Study:
- To provide Canadian physicians with the rationale behind current infective endocarditis prophylaxis guidelines.
- To summarize indications for prophylaxis.
- To detail conditions where prophylaxis is not recommended.
Main Methods:
- Review of the 2007 American Heart Association guidelines on infective endocarditis prophylaxis.
- Analysis of current data regarding bacteremia and infective endocarditis.
- Focus on identifying high-risk patient groups and procedures.
Main Results:
- Significant reduction in the number of target patient groups and procedures requiring prophylaxis.
- Emphasis shifted to patients at highest risk for adverse outcomes.
- Clarification of when prophylaxis is not indicated.
Conclusions:
- Current guidelines reflect a more targeted approach to infective endocarditis prophylaxis.
- Prophylaxis is recommended only for specific high-risk individuals and procedures.
- Physicians need to be aware of updated indications and contraindications.

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:29Endocarditis IV: Nursing Management
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:14Myocarditis III: Medical Management
Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...
01:22Myocarditis IV: Nursing Management
Myocarditis is an inflammatory condition of the myocardium requiring meticulous nursing management for optimal patient outcomes. Effective management begins with a thorough assessment of the patient's medical history, paying close attention to past infections, autoimmune disorders, travel history, and exposure to toxins or drugs. Recent viral infections and systemic diseases are particularly relevant due to their potential role in triggering myocarditis.Physical Examination and MonitoringThe...
