Summary
The Mealtime Assessment Scale (MAS) shows preliminary validity for assessing swallowing efficacy and safety. While reliable for efficacy, further validation is needed for the safety subscale in dysphagia patients.
Area of Science:
- Clinical assessment tools
- Swallowing disorders
- Dysphagia diagnostics
Background:
- The Mealtime Assessment Scale (MAS) was developed to evaluate swallowing safety and effectiveness during meals.
- Accurate assessment tools are crucial for managing patients with dysphagia.
Purpose of the Study:
- To perform a preliminary validation of the Mealtime Assessment Scale (MAS).
- Investigate internal consistency, inter-rater agreement, concurrent validity, known-group validity, and responsiveness of the MAS.
Main Methods:
- MAS was administered to 100 individuals without dysphagia and 100 with dysphagia.
- Inter-rater agreement was assessed by two clinicians evaluating 50 subjects.
- Concurrent validity was determined by correlating MAS with MASA and ASHA NOMS scales.
- Known-group validity compared MAS scores between the two groups.
Main Results:
- Internal consistency and responsiveness were confirmed for the efficacy component, but not for safety.
- High inter-rater agreement was observed for all MAS items (average deviation index <0.66).
- MAS demonstrated strong correlations with MASA and ASHA NOMS, and significant differences between patient groups.
Conclusions:
- Preliminary evidence supports the validity and reliability of the MAS for swallowing assessment.
- The internal consistency and responsiveness of the safety subscale require further investigation.
- Additional studies are necessary to fully validate the MAS instrument.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...

01:202° Amines to N-Nitrosamines: Reaction with NaNO2
5.4K
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

6.2K
The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics). Experiments confirm the existence of such a temperature, called absolute zero. An absolute temperature scale is one whose zero point is absolute zero. Such scales are convenient in science because several physical quantities, such as the volume of an ideal gas, are directly...
