Summary
Positional obstructive sleep apnea (POSA) is common in children with obesity. Identifying POSA can help tailor positional therapies for better treatment outcomes in pediatric patients.
Area of Science:
- Pediatric Sleep Medicine
- Obesity and Sleep Disorders
- Respiratory Physiology
Background:
- Obstructive sleep apnea (OSA) is prevalent in children with obesity.
- Positional obstructive sleep apnea (POSA), where events occur mainly when supine, is a recognized phenotype.
- Limited data exists on POSA prevalence and associated factors in pediatric obesity.
Purpose of the Study:
- To determine the prevalence of POSA in children with obesity.
- To identify factors associated with POSA in this population.
Main Methods:
- Cross-sectional study of 112 children (aged 8-18) with obesity undergoing polysomnography (PSG).
- POSA defined by an overall apnea-hypopnea index (OAHI) ≥5 and a supine to nonsupine OAHI ratio ≥2.
- Demographic, anthropometric, and PSG data were collected and analyzed.
Main Results:
- 38% of children with obesity had OSA (43/112).
- Of those with OSA, 58% (25/43) had POSA.
- No significant differences in age, sex, or anthropometrics were found between POSA and non-POSA groups.
Conclusions:
- POSA is a frequent phenotype in children with obesity and OSA.
- Identifying POSA is crucial for developing targeted positional therapies.
- This finding supports individualized treatment strategies for pediatric 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.

01:25Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
143
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...
