Hypersensitivities

620
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Allergic Drug Reactions

838
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Antibody Structure

60.1K
Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibodies consist of four polypeptide chains: two identical heavy...

背景情况:

  • 过敏特异性免疫疗法 (ASIT) 是对过敏性疾病的关键治疗方法.
  • 了解公众对ASIT的看法对于患者的参与和治疗坚持是很重要的.
  • 像Twitter这样的社交媒体平台提供了对公众情绪的洞察力.

研究的目的:

  • 在Twitter上分析公众对过敏原特异性免疫疗法 (ASIT) 的情绪.
  • 为了分析情绪,使用Valence Aware词典和情绪推理器 (VADER) 模型.
  • 为了追踪11年的情绪趋势.

主要方法:

  • 通过Twitter API,从2012年至2022年收集了34711条提及"过敏疫苗"的推文.
  • 通过删除URL,用户名,标签和重复内容来预处理推特.
  • 应用了VADER模型来对推特情绪进行分类 (积极,消极,中立).

主要成果:

  • 分析了32,783条相关推特,其中32.41%是负面的,31.11%是中立的,36.47%是积极的情绪.
  • 11年的平均情绪极性是0.02751,表明整体情绪中立.
  • 观察到每年平均极度的增加趋势,在2017年,2018年和2022年有显著的积极平均值.

结论:

  • 在推特上对过敏原特异性免疫治疗的整体公众情绪在分析的十年中保持中立.
  • 尽管推特数量随着时间的推移而下降,但情绪逐渐出现了积极的转变.
  • 具体年份显示,关于过敏疫苗的公共话语更加积极.
