Relative Risk01:12

Relative Risk

2.1K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.5K
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...

Primary Active Transport01:47

Primary Active Transport

198.5K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Primary and Secondary Growth in Roots and Shoots

60.5K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

326
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Area of Science:

  • Hepatology
  • Internal Medicine
  • Clinical Epidemiology

Background:

  • Primary biliary cholangitis (PBC) is a progressive chronic cholestatic liver disease.
  • A subset of patients with PBC may develop liver failure or death.
  • Accurate risk stratification is essential for identifying at-risk patients and guiding treatment.

Purpose of the Study:

  • To review established and novel prognostic factors for PBC.
  • To discuss tools for risk stratification in PBC patients.
  • To highlight the clinical applicability of these prognostic tools.

Main Methods:

  • Review of multicentre cohort studies on PBC progression.
  • Analysis of biochemical response to ursodoxycholic acid for risk stratification.
  • Evaluation of serum biomarkers (total bilirubin, alkaline phosphatase) and risk scores (GLOBE, UK-PBC).

Main Results:

  • Biochemical response to ursodoxycholic acid identifies patients who may benefit from additional therapies.
  • Serum total bilirubin and alkaline phosphatase are validated biomarkers for long-term PBC outcomes.
  • The GLOBE and UK-PBC risk scores offer individualized risk prediction for PBC patients.

Conclusions:

  • Established and emerging prognostic tools enhance risk stratification in PBC.
  • Personalized risk prediction aids in tailoring management strategies for PBC.
  • Further research and clinical application of these tools can improve patient outcomes.
