Abstract

Insights

Older adults stung by wasps face a high risk of multiple organ dysfunction syndrome (MODS). Advanced age, sting severity, and complications like acute kidney injury (AKI) and acute respiratory distress syndrome (ARDS) are key risk factors.

Area of Science:

  • Toxicology
  • Geriatrics
  • Critical Care Medicine

Background:

  • Wasp stings can lead to severe systemic reactions.
  • Older adults are a vulnerable population susceptible to adverse outcomes from envenomation.

Purpose of the Study:

  • To investigate the clinical features and risk factors for short-term multiple organ dysfunction syndrome (MODS) in elderly individuals following wasp stings.
  • To identify predictors of MODS in this specific demographic.

Main Methods:

  • Retrospective analysis of demographic, clinical, and laboratory data from patients aged over 65 who experienced wasp stings.
  • Comparison of clinical data between patients who developed MODS and those who did not.
  • Logistic regression analysis to identify independent risk factors for MODS.

Main Results:

  • 118 patients were analyzed; 49 developed MODS.
  • Significant differences between MODS and non-MODS groups included age, pre-hospital time, and need for advanced life support.
  • Acute kidney injury (AKI) and acute respiratory distress syndrome (ARDS) were the most frequent complications, significantly higher in the MODS group.
  • Independent risk factors for MODS were advanced age, number of stings, prolonged pre-hospital time, and the presence of AKI and ARDS.

Conclusions:

  • Older adults are at high risk for MODS after wasp stings.
  • AKI and ARDS are critical complications associated with MODS in this population.
  • Clinicians should utilize age, sting burden, pre-hospital duration, AKI, and ARDS to assess risk and guide early, targeted interventions for improved outcomes.

Anticholinesterase Agents: Poisoning and Treatment

Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.     
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...
