まとめ
この研究では,乳がんの早期発見のための臨床乳房検査 (CBE) と対比して,iBreastExam (iBE) 装置を評価した. iBEはCBEとの高い合意を示したが,広範なスクリーニングプログラムの展開にはさらなる精細化が必要である.
科学分野:
- 腫瘍学
- 公衆衛生
- 医療機器
背景:
- 低・中所得国 (LMIC) での乳がんの負担の増加
- 低所得国におけるマンモグラフィー検診のインフラが限られている.
- 臨床乳房検査 (CBE) は実行可能だが主観的なスクリーニング方法である.
研究 の 目的:
- 乳がんの早期発見のための iBreastExam (iBE) とCBEの合意を評価する.
- 資源の限られた環境でCBEの代替または補足としてのiBEの可能性を評価する.
主な方法:
- 40歳から69歳までの9994人の女性を対象とした横断的な研究.
- 訓練を受けた医療提供者によるCBEとiBEによる独立したスクリーニング
- 陽性の症例は専門外科医に紹介され,その後診断手順 (マンモグラフィー,超音波,生検) を行う.
主要な成果:
- CBEとiBEの間の総合意額は99.5% (カッパ=0.78) であった.
- 検診された9994人の女性のうち14例の乳がんが検出されました (0. 14%).
- 3 女性の乳がんはCBEで陽性だが,iBEでは陰性だった.
結論:
- iBreastExamは,臨床乳房検査と非常に一致しています.
- 信頼性の高い乳がんスクリーニングのために,iBEの感受性をさらに精錬する必要があります.
- iBEをスクリーニングプログラムに広く導入する前に,さらなる研究が必要である.

Pulmonary Tuberculosis I
321
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Assessment of blood pressure in brachial artery(two-step method)
892
Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Clinical Trials
7.5K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Pulmonary Tuberculosis II
339
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
