- ウイルス学
- 流行病学
- 公衆衛生
背景:
- COVID-19 パンデミックは,ウイルス性呼吸器感染症の正常なパターンを大きく破壊し,その循環と季節性に影響を与えた.
- SARS-CoV-2が他の呼吸器ウイルスに与える影響を理解することは,公衆衛生と臨床ケアを管理するために極めて重要です.
研究 の 目的:
- イタリア南部におけるウイルス性呼吸器感染症の頻度に対するSARS-CoV-2の影響を評価する.
- COVID-19 パンデミック前,中,後におけるウイルスの循環と季節性を比較する.
- SARS-CoV-2の出現が他の呼吸器ウイルスにどのように影響したかを調査する.
主な方法:
- 学術病院からの鼻のサンプルを分析した過去と今後の研究.
- サンプルは,COVID-19以前の期間とCOVID-19後の期間に分類されました.
- 呼吸器系ウイルスが特定され,その有病率と共感染パターンが分析されました.
主要な成果:
- 全体として,3930件のサンプルのうち20%が呼吸器ウイルスに陽性であった.高齢者 (65~98歳) の陽性率は高かった.
- パンデミック前は,インフルエンザAが最も一般的であった. パンデミックの間は,SARS-CoV-2が優勢であった. パンデミック後,SARS-CoV-2は減少したが,インフルエンザAは増加した.

Common Respiratory Disorders
898
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Respiratory Capacities
884
Respiratory capacities are crucial indicators of lung function, representing the maximum amount of air an individual's respiratory system can handle during various breathing phases.
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

Respiratory Volumes and Capacities
2.7K
The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide from the body. Respiratory volumes describe the volume of air in the lungs at different phases of the respiratory cycle. Tidal volume is the air breathed in and out during normal, quiet breathing. Inspiratory reserve volume is the air that can be forcefully inspired beyond the tidal volume. In contrast, expiratory reserve volume refers to the air that can be expelled from the lungs after a normal...

Respiratory Volumes
1.7K
Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Respiratory Volumes and Capacities I

Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
