Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

269
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacokinetics in Pediatric Patients: Drug Excretion

259
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Drug Dosing: Obese Patients

263
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Pharmacodynamics in Geriatric Patients: Effects of Age

234
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...

Immunological Memory01:23

Immunological Memory

16.8K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Patient-centered Care01:13

Patient-centered Care

3.0K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

    Summary

    Immunological abnormalities, including elevated immunoglobulins and complement factors, are present in ankylosing spondylitis (AS). Specific lymphocyte subset changes correlate with disease activity, suggesting a role in AS pathogenesis.

    Area of Science:

    • Immunology
    • Rheumatology

    Background:

    • Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily affecting the axial skeleton.
    • Understanding the immunological underpinnings of AS is crucial for developing targeted therapies.

    Purpose of the Study:

    • To investigate alterations in humoral and cellular immunity in patients with ankylosing spondylitis.
    • To correlate immunological changes with disease activity in AS.

    Main Methods:

    • Serum levels of IgG, IgA, IgM, C3, and C4 were measured.
    • Lymphocyte subpopulations (B cells, OKT3, OKT8, OKIa1) were analyzed using monoclonal antibodies.
    • Patients were stratified into active (CRP ≥ 15 mg/l) and inactive (CRP < 15 mg/l) groups.

    Main Results:

    • AS patients exhibited significantly higher IgG and IgA levels, and increased C3 and C4 compared to healthy controls.
    • A decrease in B cells and OKT3+ cells, with an increase in OKT8+ and OKIa1+ cells, was observed in AS patients.
    • Active AS patients showed a higher percentage of OKT8+ and OKIa1+ cells and lower OKT3+ cells compared to inactive patients and controls.

    Conclusions:

    • Immunological aberrations are evident in ankylosing spondylitis.
    • Specific lymphocyte subset alterations are associated with disease activity, implicating immune dysregulation in AS pathogenesis.
