Infection01:20

Infection

11.6K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Urinary Tract Infection II: Pathophysiology

524
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Cystic Fibrosis: Pathogenesis

676
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Stages of Infection01:26

Stages of Infection

64.7K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

2.6K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

科学领域:

  • 神经病理学神经病理学
  • 公共卫生 公共卫生
  • 社会流行病学 社会流行病学

背景情况:

  • 阿尔茨海默病和相关痴呆症 (ADRD) 是复杂的,与社会经济因素有关.
  • 结构上的不平等,例如生活在弱势社区 (根据区域贫困指数 - ADI进行索引),增加了ADRD风险.
  • 脑血管疾病 (CVD) 是痴呆症中常见的共患病,但它与邻居剥夺的关系未得到充分研究.

研究的目的:

  • 调查社区贫困 (ADI) 与脑血管疾病 (CVD) 神经病理学的存在之间的联系.
  • 分析来自邻里研究中的国家大脑银行捐赠者样本的数据.
  • 了解更高的社区贫困是否预测多元化的队列中的心血管疾病.

主要方法:

  • 利用来自21个阿尔茨海默氏病研究中心 (ADRC) 的7,187名脑捐赠者参与者的数据.
  • 将死亡时的捐赠者地址链接到国家ADI百分位数,分类为第三类.
  • 评估CVD神经病理学 (心脏病发作,出血,微心脏病发作,白质稀缺) 使用NACC数据和后勤回归,根据性别,年龄和APOE状态进行调整.

主要成果:

  • 大约25%的捐赠者居住在贫困地区,52%的捐赠者患有心血管疾病.
  • 增加的ADI显著预测了心血管疾病神经病变的更高几率 (OR = 1.16,p < .001).

结论:

  • 在国家大脑捐赠者队列中,更高的邻居贫困与心血管疾病神经病理病的几率增加有关.
  • 研究结果表明,社会经济劣势和脑血管病理之间存在联系.
  • 需要进一步的研究来阐明驱动这些协会的机制.
