Summary
Global research on nutrition and frailty is growing, led by the US and China. Key research gaps include a lack of mechanistic insights and interventional trials for frailty prevention and treatment.
Area of Science:
- Gerontology and Nutritional Science
- Public Health and Aging Research
Background:
- Frailty is a critical indicator of aging health, characterized by multisystem decline.
- Nutrition is a significant modifiable factor influencing frailty development and progression.
Purpose of the Study:
- To conduct a systematic scientometric analysis of global research trends in nutrition and frailty.
- To identify key contributors, collaboration patterns, and thematic evolution in this field.
- To address a significant gap in understanding the nutrition-frailty relationship.
Main Methods:
- Systematic retrieval of 754 publications (2000-2024) from the Web of Science Core Collection.
- Bibliometric analysis using VOSviewer, CiteSpace, and R package bibliometrix.
- Structured literature review of 257 studies to synthesize findings.
Main Results:
- Consistent growth in publications, with the US and China as leading contributors.
- Nutrients journal published most frequently; Journals of Gerontology Series A was most co-cited.
- Frailty prevention and treatment identified as predominant research focus, with identified gaps in mechanistic and personalized nutrition.
Conclusions:
- The study maps the intellectual landscape of nutrition and frailty research.
- Identified critical research voids: overreliance on observational data, scarcity of interventional trials, and limited global diversity.
- Provides direction for future interdisciplinary investigations into nutrition and frailty.

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
183
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
180
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...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
216
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...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
212
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...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
221
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
