まとめ
アプローチバイアス修正(ApBM)は、標準治療への追加によって喫煙中止率を改善しませんでした。この研究では、ApBM、偽薬トレーニング、または標準治療単独と比較して、長期禁煙率に有意差は見られませんでした。
科学分野:
- 行動科学
- 臨床心理学
- 依存症医学
背景:
- 喫煙は喫煙キューに対するアプローチバイアスと関連しています。アプローチバイアス修正(ApBM)はアルコール使用障害に有望ですが、喫煙中止における有効性は不明です。
研究 の 目的:
- 喫煙中止治療の補助としてのApBMが、対照群と比較して6ヶ月の長期禁煙率を増加させるかどうかを評価すること。
主な方法:
- 標準的な喫煙中止治療(TAU)を受けている351人の参加者を対象としたランダム化、対照、二重盲検試験。参加者は7日間、TAU + ApBM、TAU +偽薬トレーニング、またはTAU単独にランダムに割り付けられました。主要評価項目は、連続した禁煙と低い一酸化炭素レベルによって定義される6ヶ月後の長期禁煙でした。
主要な成果:
- 6ヶ月の禁煙率は、TAU+ApBM群で19.3%、TAU+偽薬群で17.4%、TAU単独群で16.2%でした。3群間で禁煙率に統計学的に有意な差は認められませんでした。
結論:
- 喫煙中止治療への追加としてのApBMは、偽薬トレーニングまたは標準治療単独よりも優れていません。アルコール使用障害におけるApBMの肯定的な効果は、タバコ使用障害には及ばないことが示唆されています。

Confirmation Biases
8.2K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Hindsight Biases
4.3K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
473
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Bias
7.4K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Histone Modification
16.2K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.

Spreading of Chromatin Modifications
9.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.
