Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

14.1K
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...

Genome-wide Association Studies-GWAS

15.9K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Gastritis-II: Pathophysiology

1.5K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Factors Affecting Protein-Drug Binding: Patient-Related Factors

380
Protein-drug binding, a pivotal aspect of pharmacokinetics, is subject to considerable variability influenced by an array of patient-related factors. The intricate interplay of age, individual differences, and pathological conditions significantly impact the binding dynamics and subsequent pharmacological effects.
Age stands as a key determinant in protein-drug binding. Neonates, characterized by low albumin content, experience heightened concentrations of unbound drugs such as phenytoin and...

Factors Affecting Illness01:18

Factors Affecting Illness

5.5K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Area of Science:

  • Immunology
  • Rheumatology
  • Metabolic Disorders

Background:

  • Acute gout arthritis flares are a major cause of impaired quality of life and increasing healthcare burdens.
  • Gout management faces challenges due to comorbidities and rising hospital admission rates.
  • Chronic gouty arthritis can lead to joint damage and functional limitations.

Purpose of the Study:

  • To review new knowledge on the variability of responses to urate crystals in gout.
  • To explore factors influencing gout flare unpredictability and self-limitation.
  • To identify potential new targets for gout prevention and treatment.

Main Methods:

  • Review of current literature on innate immunity and inflammasome activation in gout.
  • Analysis of the interplay between diet, metabolism, and inflammation in gouty arthritis.
  • Examination of genetic, epigenetic, and microbiome influences on gout flares.

Main Results:

  • Innate immunity and inflammasome activation are key to gout flare responses.
  • Diet, metabolism, nutritional sensing, microbiome, and phagocyte behavior influence gout variability.
  • Endogenous regulators, nutritional biosensors, and genetic factors play significant roles.
