まとめ
阻害性睡眠無呼吸 (OSA) の継続的な陽性気道圧 (CPAP) は,エネルギー消費または摂取を大幅に変化させることなく,主に脂肪のない質量 (FFM) から体重増加を引き起こす可能性があります. これは,潜在的に有害な代謝効果に関連していない微妙な正のエネルギーバランスを示唆しています.
科学分野:
- 睡眠医学
- 代謝に関する研究
- 心臓呼吸器生理学
背景:
- 阻害性睡眠時無呼吸 (OSA) は,継続的な陽性呼吸道圧 (CPAP) で治療される一般的な状態です.
- 体重増加は,OSA患者のCPAP開始後に一般的に観察される現象です.
- CPAPに関連した体重増加の根本的なメカニズムと臨床的関連性は,まだ完全に理解されていません.
研究 の 目的:
- OSA患者におけるCPAP療法のエネルギー消費,食事摂取,体調,身体活動,食欲調節ホルモンの影響を調査する.
- OSAのCPAP治療中に観察された体重増加に寄与するメカニズムを解明する.
- CPAPによる体重変化が有害な代謝変化と関連しているかどうかを判断する.
主な方法:
- 12週間のCPAP治療と非アクティブな対照群を比較したOSA患者によるオープンランドマイズされた制御試験.
- 主要の結果は,休息時のエネルギー消費 (REE) であり,次要の結果は,カロリー摂取量,脂肪量 (FM),無脂肪量 (FFM) および身体活動でした.
- 摂食を調節するホルモンの変化を評価した第3段階のアウトカム. 分析では,治療の意図 (ITT) とプロトコルごとにアプローチが用いられました.
主要な成果:
- CPAP治療は,休息時のエネルギー消費量 (REE) や総カロリー摂取量に有意な影響を及ぼさなかった.
- CPAP群では夕方の体重とボディマス指数の有意な増加が観察されました.
- CPAP治療により,脂肪のない質量 (FFM),アシレートされたグリリン,インスリン類似成長因子1が増加し,コルチゾールと認知抑制が低下した.
結論:
- OSA患者におけるCPAP誘発の体重増加は,主に脂肪の量ではなく,脂肪フリーマスの増加によるようです.
- 体重増加は,休息時のエネルギー消費,体力活動,カロリー摂取の大きな変化なしに起こっており,微妙な正のエネルギーバランスを示唆しています.
- CPAPの代謝影響の評価は,観察された増加が有害な代謝結果を示さない可能性があるため,全体重にのみ焦点を当てることよりも,体組成の変化 (例えば,FFM) を考慮する必要があります.

Sleep Apnea
220
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.

Mechanical Ventilation III: Noninvasive Ventilation
224
Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Physiological Control of Respiration
3.2K
Introduction
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
317
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
