Summary
Screening for staghorn stones every two years in individuals aged 30-70 is cost-effective, preventing renal failure and saving healthcare costs. This approach offers significant savings per person compared to no screening.
Area of Science:
- Nephrology
- Health Economics
- Preventive Medicine
Background:
- Staghorn stones are a significant cause of kidney damage and renal failure.
- Early diagnosis through screening can prevent kidney damage.
- Cost-effectiveness analysis is crucial before implementing screening programs.
Purpose of the Study:
- To calculate the cost-effectiveness of screening for staghorn stones.
- To compare screening versus no screening strategies for staghorn stones.
- To determine the optimal screening interval and age group.
Main Methods:
- A decision tree model was used to calculate screening costs and effectiveness.
- Effectiveness was measured by the number of prevented renal failure cases.
- Incremental Cost-Effectiveness Ratio (ICER) was calculated and compared with WHO standards.
Main Results:
- Screening increased costs by $4,861,783 USD but prevented 100 cases of renal failure.
- The ICER was $48,618 USD per additional case of renal failure prevented.
- Screening individuals aged 30-70 every two years was the most cost-effective strategy.
Conclusions:
- Bi-annual screening for staghorn stones in the 30-70 age group is cost-effective.
- The recommended screening strategy aligns with WHO guidelines.
- This approach can save approximately $3,026 USD per person in healthcare costs.

01:30Types of Building Stone
440
Building stones, essential materials for construction, are extracted from natural rock deposits and processed into specific forms and dimensions suitable for various building applications. These stones are broadly classified into three types based on their geological formation: igneous, sedimentary, and metamorphic.
Igneous rocks are formed from the solidification of magma or lava. An example is granite, known for its durability and resistance to weathering, making it ideal for parts of...

01:15Quarrying of Stone
580
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

01:29Stone Masonry
464
Stone masonry is a construction technique that uses individual stones to build structures and can be categorized into two main types: rubble and ashlar. Rubble masonry uses uneven, naturally shaped stones such as river rocks or fragments from quarries. This method often requires the mason to select and possibly shape each stone to fit the designated space, ensuring a proper build, even with irregular stone sizes and shapes. Ashlar masonry, on the other hand, employs uniformly cut stones that...

02:19Buffer Effectiveness
55.2K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

02:59Biological Effects of Radiation
17.9K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
