要旨

Aim:

Upper airway anatomy is important in obstructive sleep apnea (OSA). This study conducted a correlation analysis between the apnea-hypopnea index (AHI) score and upper airway measurements obtained from cone-beam computed tomography (CBCT), arch measurements obtained from diagnostic casts, and subjective data from patients' records, including the Berlin Sleep Questionnaire and Epworth Sleepiness Scale.

Methods:

Twenty-five subjects with a confirmed diagnosis of OSA via polysomnography with a mean AHI of 25.5 (SD18.5) were enrolled in this study.

Results:

A significant correlation was found between the AHI score and the following factors: male sex, obesity categories, Berlin questionnaire category, sleep efficiency, and maxillary intermolar width measured between the mesiobuccal cusp tip of the right and left first molars. Airway measurements from CBCT, including anterior cranial base length, facial proportion, and the length of the soft palate in the mid-sagittal plane and the retroglossal area in the axial plane, were significantly correlated with the AHI score.

Conclusion:

In addition to male gender and obesity, anatomic factors related to upper airway measurements on CBCT are significantly correlated with AHI, indicating upper airway limitations, OSA severity, and aiding early diagnosis.

Drug-Induced Sleep Endoscopy (DISE) with Target Controlled Infusion (TCI) and Bispectral Analysis in Obstructive Sleep Apnea

The aim of this study was to establish a standardized protocol for sleep endoscopy to differentiate obstruction patterns in obstructive sleep apnea (OSA). Target-controlled infusion (TCI) of the sedative was combined with real-time monitoring of the depth of sedation using bispectral...

Sleep Apnea

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Bioavailability: Influencing Factors

Bioavailability: Influencing Factors

Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...

Factors Influencing Microbial Growth: pH

Factors Influencing Microbial Growth: pH

Microorganisms are classified as acidophiles, neutrophiles, or alkaliphiles based on their pH growth preferences, reflecting their adaptations to specific environments. Maintaining a stable intracellular pH is critical for macromolecular stability and enzymatic activity, which can be challenged by external pH variations.Neutrophiles, such as Escherichia coli, grow optimally between pH 5.5 and 8.0. These microorganisms inhabit neutral or slightly acidic environments and employ mechanisms like...

Persuasion: Motivational Factors Influencing Attitude Change

Source: William Brady & Jay Van Bavel—New York University
Decades of social psychological research sought to understand a fundamental question that pervades our social life including politics, marketing and public health; namely, how are people persuaded to change their attitudes towards an idea, person, or object? Traditional work found that there are key factors that influence whether persuasion is successful or not including the source of the persuasive message ("source"),...
