概括
维生素D补充剂在COVID-19期间改善了军人新兵的血清水平,但并没有显著降低SARS-CoV-2血清转化率. 机构的对策也未能在未接种疫苗的人群中防止感染传播.
科学领域:
- 免疫学 免疫学 免疫学
- 营养科学 营养科学
- 流行病学 流行病学
背景情况:
- 由于COVID-19的流行,武装部队的准备就受到威胁.
- 观察到无症状的SARS-CoV-2传播和与低维生素D状态的潜在联系.
- 需要进行研究来评估维生素D补充剂对军事人员感染的影响.
研究的目的:
- 为了前性地确定军事新兵和大学队伍中的SARS-CoV-2血清转化率.
- 为了测试维生素D补充剂会影响血清转换的假设.
- 评估机构对抗COVID-19传播措施的有效性.
主要方法:
- 在英格兰北部招募了两个队伍 (军事新兵和大学生).
- 军事新兵接受维生素D补充剂,而大学生担任对照.
- 维生素D水平和抗SARS-CoV-2抗体通过多个时间点的血液样本进行测量.
主要成果:
- 与大学生 (25.7%) 相比,军人新兵 (44.4%) 的血清转化率更高.
- 军事新兵在补充剂后的维生素D水平较高,尽管有坚持问题的问题.
- 维生素D的负面变化与新兵的血清转化有关,但不是大学生.
结论:
- 机构反制措施没有减少未接种疫苗的步兵新兵中SARS-CoV-2感染.
- 维生素D补充剂增加了血清维生素D水平,但对血清转化缺乏临床显著影响.
- 可能需要进一步的研究来探索维生素D在军事环境中预防感染的作用.

Cognitive Dissonance
32.3K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Transmission-based Precautions II: Airborne and Protective Environment
1.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Factors Affecting the Risk of Infection
10.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Controls in Experiments
6.9K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Immunological Memory
505
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...
