Summary
Most employees return to work after total hip arthroplasty (THA). Key factors for successful return to work include fewer sick days before surgery, higher job positions, and a healthy BMI, while obesity and manual labor pose risks.
Area of Science:
- Orthopedic Surgery
- Occupational Health
- Public Health
Background:
- Increasing number of working-age individuals undergoing total hip arthroplasty (THA).
- Limited understanding of factors influencing return to work (RTW) post-THA.
- Need to identify predictors of RTW for this demographic.
Purpose of the Study:
- Identify risk factors for return to work (RTW) after total hip arthroplasty (THA).
- Analyze demographic, general health, health risk behaviors, and socioeconomic status variables.
- Inform strategies to improve RTW rates in working-age THA patients.
Main Methods:
- Study cohort: 408 employees from the Finnish Public Sector (FPS) who underwent THA.
- Data sources: National health registers and FPS surveys for pre-operative information.
- Statistical analysis: Cox proportional hazard modeling to assess RTW likelihood.
Main Results:
- High RTW rate: 94% of patients returned to work post-THA.
- Average recovery time: 3 months (range: 10 days to 1 year).
- Significant predictors of RTW: <30 pre-operative sick days (HR 1.8), higher occupational position (HR 2.2), BMI < 30 (HR 1.4).
- Non-significant factors: Age, sex, general health, health-risk behaviors.
Conclusions:
- The majority of employees successfully return to work after THA.
- Pre-operative factors like sick leave duration, job type, and BMI significantly impact RTW.
- Obesity and manual labor combined with prolonged pre-operative sick leave increase the risk of not returning to work.

01:04Venous Return
12.0K
The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

01:12Total Voids in Concrete
479
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

01:47Primary Active Transport
197.8K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

01:05Total Internal Reflection Fluorescence Microscopy
11.1K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
