Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

5.5K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Common Respiratory Disorders01:31

Common Respiratory Disorders

997
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

2.0K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

232
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Acute Respiratory Failure-I01:21

Acute Respiratory Failure-I

386
Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

422
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Area of Science:

  • Virology
  • Epidemiology
  • Infectious Diseases

Background:

  • Human respiratory syncytial virus (RSV) is a negative-sense single-stranded RNA virus responsible for seasonal respiratory epidemics.
  • RSV typically exhibits two predominant genotypes (A and B) that alternate annually, with regional variations.
  • The virus poses a significant health risk, causing disease and mortality in pediatric and elderly populations, as well as immunocompromised individuals.

Purpose of the Study:

  • To clarify the clinical impact of RSV in hospitalized adult populations.
  • To highlight the role of multiplex molecular assays in understanding RSV's prevalence and effects.
  • To provide an overview of current therapeutic and preventative strategies under development.

Main Methods:

  • Utilized multiplex molecular assays to expand the understanding of RSV in hospitalized adults.
  • Reviewed clinical data to assess the spectrum of RSV-related symptoms and complications.
  • Analyzed the epidemiology of RSV genotypes (A and B) and their seasonal patterns.

Main Results:

  • Expanded use of molecular assays has clarified the clinical impact of RSV in hospitalized adults.
  • RSV infection in adults can range from upper respiratory tract infections to severe lower respiratory tract infections.
  • RSV exacerbations of pre-existing cardiac and lung conditions are significant concerns in adult patients.

Conclusions:

  • RSV is a critical pathogen affecting adults, leading to diverse respiratory illnesses and exacerbations of chronic conditions.
  • Multiplex assays are crucial for accurate RSV diagnosis and understanding its clinical burden in adults.
  • While supportive care remains primary, the development of novel therapeutic and preventative options offers future hope for managing RSV.
