Insights

Respiratory syncytial virus (RSV) causes significant hospitalizations in Louisiana children under one year old, primarily with bronchiolitis. Immunoprophylaxis is recommended during the November to March RSV season.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Public Health

Background:

  • Respiratory syncytial virus (RSV) is a leading cause of infant bronchiolitis and pneumonia globally.
  • Understanding the epidemiology of RSV hospitalizations is crucial for public health interventions.

Purpose of the Study:

  • To determine the burden of RSV hospitalizations in Louisiana from 1999 to 2010.
  • To identify demographic and seasonal patterns of RSV infections in hospitalized children.

Main Methods:

  • Utilized Louisiana Inpatient Hospital Discharge Data from 1999-2010.
  • Identified cases using RSV diagnosis codes.
  • Analyzed hospitalization rates, age distribution, and seasonality.

Main Results:

  • 2,000-3,000 annual RSV hospitalizations occurred, with rates of 37.2-71.4 per 100,000 population.
  • Bronchiolitis was the primary diagnosis (79%), predominantly affecting infants under one year (44% aged 0-3 months).
  • The RSV season spanned November to March; most infections (96.1%) were community-acquired.

Conclusions:

  • RSV poses a substantial burden on Louisiana's pediatric population, particularly young infants.
  • Targeted immunoprophylaxis during the identified RSV season is recommended for high-risk infants.
  • The findings support public health strategies for RSV prevention and management in this region.

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

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:
Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

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...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Common Respiratory Disorders01:31

Common Respiratory Disorders

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,...

Rous Sarcoma Virus (RSV) and Cancer

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...
