Summary
Frailty trajectories before and after hip fracture significantly impact mortality risk in older adults. Identifying progressive frailty post-hip fracture is crucial for targeted interventions and improved survival.
Area of Science:
- Gerontology
- Geriatric Medicine
- Public Health
Background:
- Hip fractures pose significant health risks for older adults.
- Understanding frailty evolution around hip fractures and its mortality impact is critical.
Purpose of the Study:
- Investigate frailty trajectories before and after hip fracture.
- Determine the association between these frailty trajectories and subsequent mortality risk.
Main Methods:
- Population-based cohort study using UK Biobank data (n=4963).
- Assessed frailty using Hospital Frailty Risk Score and ICD-10 codes.
- Latent class trajectory analysis modeled pre- and post-fracture frailty trends.
Main Results:
- Identified three pre-fracture (robust, moderate, progressive) and three post-fracture (stable moderate, stable high, progressive) frailty trajectories.
- Progressively frail individuals showed increased frailty pre-fracture.
- Higher pre-fracture frailty predicted greater post-fracture frailty; highest mortality risk seen in rapidly progressive post-fracture frailty.
Conclusions:
- Distinct frailty trajectories before and after hip fracture are linked to varied mortality risks.
- Routine frailty assessments are needed to identify high-risk individuals.
- Targeted interventions can improve recovery and survival in hip fracture patients.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:27Fractures: Bone Repair
5.1K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:19The Effect of Aging on Tissues
3.3K
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...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
234
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...
