Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

2.7K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

12.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.3K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Infection01:20

Infection

8.4K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

13
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...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

17
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Area of Science:

  • Orthopaedic surgery
  • Infectious diseases
  • Biomedical engineering

Background:

  • Orthopaedic infections are a major complication following surgery with internal devices, affecting approximately 5% of patients.
  • These infections lead to significantly higher hospital costs and poorer patient outcomes, including reduced function and increased pain.
  • Understanding the "race for the surface"—the temporal relationship between bacterial colonization and host-cell integration—is crucial for developing new treatments.

Purpose of the Study:

  • To review current and emerging strategies for the prevention and treatment of orthopaedic infections.
  • To highlight advancements in understanding the pathogenesis of these infections.
  • To discuss the evolving landscape of therapeutic options.

Main Methods:

  • Review of existing literature on orthopaedic infection prevention and treatment.
  • Analysis of recent studies on antibiotic efficacy and novel therapeutic approaches.
  • Exploration of host modulation and antibiotic powder use for prevention.

Main Results:

  • Oral antibiotics show comparable efficacy to intravenous antibiotics for orthopaedic infections.
  • Host modulation and antibiotic powders are promising for infection prevention.
  • Understanding bacterial-host interactions is key to new treatment development.

Conclusions:

  • Orthopaedic infections remain a complex clinical challenge requiring ongoing research and innovation.
  • Evolving prevention strategies, such as host modulation and antibiotic powders, show promise in reducing infection rates.
  • Advancements in treatment, including the use of oral antibiotics, are improving patient outcomes.
