概括
社交媒体提供癌症信息,但覆盖范围不平衡. 医疗社交媒体 (MSM) 和普通社交媒体 (CSM) 的重点不同,强调需要更广泛的癌症预防和治疗内容.
科学领域:
- 医疗传播中的大数据分析.
- 机器学习用于对健康信息的内容分析.
- 社交媒体在公共卫生传播中的作用.
背景情况:
- 社交媒体对于癌症预防和治疗信息的传播至关重要.
- 在社交媒体平台上对癌症综合信息的理解有限.
- 医学社交媒体 (MSM) 和普通社交媒体 (CSM) 的比较研究很少.
研究的目的:
- 通过大数据分析,全面地图化MSM和CSM的癌症治疗和预防信息特征.
- 提高癌症覆盖率,支持患者明智地做出治疗决策.
主要方法:
- 从4个MSM和5个CSM的微信官方账户收集了60,843条帖子.
- 应用潜伏迪里克莱特分配 (LDA) 主题建模,提取8427个与癌症相关的帖子.
- 利用来自变压器 (BERT) 和GloVe的双向编码器表示来实现内容的自动化多标签分类.
主要成果:
- 分析了8427篇与癌症相关的文章;35.52%包含预防和44.43%的治疗信息.
- CSM专注于生活方式预防 (例如,饮食,运动),而MSM强调医疗方面 (例如,查,疫苗接种).
- 两个平台都显示辐射预防和母乳养的覆盖范围有限;CSM (35.52%) 更多地关注预防,而不是MSM (13.49%).
结论:
- 社交媒体上的癌症信息缺乏平衡,只关注具体的预防和治疗方面.
- 需要在社交媒体平台上更广泛地覆盖癌症预防措施和治疗方法.
- 机器学习提供了一种有前途的方法,用于分析和绘制社会媒体上的健康信息维度,以促进健康.

Targeted Cancer Therapies
7.5K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Cancer Survival Analysis
334
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Combination Therapies and Personalized Medicine
4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Treatment Resistant Cancers
3.3K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Mouse Models of Cancer Study
5.5K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
