Hepatitis B surveillance in Canada: 2005-2012.
Summary
Hepatitis B (HB) infection rates declined in Canada from 2005-2012. Acute HB cases saw a notable decrease, while chronic HB rates also trended downwards, indicating progress in public health surveillance.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- Hepatitis B (HB) remains a significant global health concern.
- Understanding surveillance trends is crucial for effective public health interventions.
- Previous analyses lacked detailed differentiation between acute and chronic HB infection statuses.
Purpose of the Study:
- To analyze surveillance trends of Hepatitis B (HB) in Canada from 2005 to 2012.
- To examine trends by age, sex, and infection status (acute vs. chronic).
- To provide insights into the evolving epidemiology of HB in Canada.
Main Methods:
- Utilized national surveillance data from the Canadian Notifiable Disease Surveillance System.
- Compiled data on acute and chronic HB cases reported between 2005 and 2012.
- Analyzed trends by age, sex, and infection status over the specified period.
Main Results:
- Reported acute HB infection rates decreased from 1.0 to 0.6 per 100,000 population.
- Acute HB rates were consistently higher in males than females.
- Reported chronic HB infection rates decreased from 14.1 to 12.0 per 100,000 population (2009-2012).
Conclusions:
- This study provides the first comprehensive analysis of HB trends by infection status using Canadian national data.
- Canada is experiencing a downward trend in overall HB rates, particularly for acute infections.
- Enhanced national capacity to differentiate acute from chronic HB is recommended for improved understanding of transmission and disease burden.

01:26Principles of Disease Surveillance
570
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

01:25Immune Surveillance by NK Cells and Phagocytes
8.9K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

01:08Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
281
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

01:21Hepatic Portal System

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
248
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

01:16Hepatic Drug Excretion: Influencing Factors
599
The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...
