Summary
Immunosenescence, or aging-related immune decline, increases elderly susceptibility to infections like cysticercosis. This study found cysticercosis is common in older adults, potentially linked to increased cancer risk.
Area of Science:
- Immunology
- Pathology
- Epidemiology
Background:
- Immunosenescence, a hallmark of aging, compromises immune defenses.
- Elderly individuals exhibit increased susceptibility to infections, neoplasia, and parasitic diseases, including cysticercosis.
Purpose of the Study:
- To compare the epidemiological and anatomopathological features of cysticercosis in elderly versus non-elderly patients.
- To investigate the potential association between cysticercosis, immunosenescence, and neoplasia in the elderly.
Main Methods:
- Retrospective review of 72 autopsy protocols and specimens.
- Categorization of patients into three groups: elderly with cysticercosis, non-elderly with cysticercosis, and a control group without cysticercosis.
Main Results:
- Cysticercosis was identified in 27.8% of elderly patients.
- Elderly patients predominantly presented with neurocysticercosis (80%) and cardiac cysticercosis (20%), with early parasitic stages (75%).
- Neoplastic and cardiovascular diseases were significantly more frequent causes of death in the elderly cysticercosis group compared to non-elderly.
Conclusions:
- Cysticercosis is prevalent in the elderly population.
- Immunosenescence, potentially exacerbated by cysticercosis, may create conditions favorable for neoplasia development in older adults.
- Continuous parasitic infection throughout aging may contribute to increased disease susceptibility.

01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:24Cystic Fibrosis: Management
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
01:15Drug Dosing: Geriatric Patients
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...
