まとめ
4つの学前期の喘息のプロファイルが特定され,母親の喘息と母乳育児の欠如が主要なリスク要因であった. これらのプロファイルは,幼児期の後期に喘息のリスクに影響を与えます.
科学分野:
- 小児アレルギー・免疫学
- 呼吸器医学とは
- エピデミオロジー エピデミオロジー
背景:
- 幼児期の喘息は一般的ですが,異質的です.
- 異なった喘息の現象型を特定することは,根本的なメカニズムを理解し,ターゲットを絞った介入を開発するために不可欠です.
- 展望的なコホート研究は,幼児期から幼少期までの喘息の軌跡と関連するリスク要因を追跡するために不可欠です.
研究 の 目的:
- 4歳までの幼稚園児における異なった喘息のプロフィールを定義する.
- これらの喘息のプロフィールに関連した早期の生命の要因を特定するために.
- これらの学前期の喘息のプロフィールが9歳の時に喘息のリスクに与える影響を決定する.
主な方法:
- ラテンクラス分析は,幼児期から4歳までの8つの喘息応答と2つの重度マーカーに基づいて,喘息のプロフィールを特定するために使用されました.
- データは,出産前の前向きなコホート研究から得られた.
- マルチノミアルロジスティック回帰を用いて,幼児期リスク因子と9歳の喘息の関連性に関する相対リスク比率 (RRR) を計算した.
主要な成果:
- 4つの学前期の喘息のプロファイルが特定されました:"決して/まれ" (n=538),"早期持続" (n=83),"一時的" (n=263),および"遅発" (n=148).
- 母親の喘息歴は,すべての不良喘息プロファイル,特に"早期持続性"喘息 (RRR 5.06) のリスクを増加させた.
- 6ヶ月の授乳は"早期の持続性"の喘息のリスクを低減させ (RRR 0.53),12ヶ月の授乳はすべての有害なプロフィールから保護された. エクゼマとアレルギーは",早期の持続性"と"遅発性"の喘息のリスクを高めました. "早期の持続性" (RRR 7.25) と"遅発性" (RRR 3.93) の喘息のプロファイルは,9歳までに喘息のリスクの増加と関連していました.
結論:
- 明確な学前期の喘息プロファイルは,特定の早期の曝露とアトピー測定値と関連しています.
- 母親の喘息と母乳育児の欠如は,有害な喘息プロフィールの重要な統合的危険因子です.
- 幼児の喘息に対する効果的な第一予防戦略を開発するために,根本的なメカニズムに関するさらなる研究が必要である.

Factors Affecting Pulmonary Ventilation
3.4K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Asthma-I: Introduction
3.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Physical Assessment of the Respiratory Tract IV: Auscultation
2.7K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Assessment of Respiration
2.1K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Respiratory System Abnormal Finding II: Palpation and Auscultation
1.6K
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Asthma-II: Pathophysiology and Classification
4.6K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
