Regulation of Food Intake01:30

Regulation of Food Intake

208
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Anorexia Nervosa01:28

Anorexia Nervosa

56
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Taste Buds and Receptors

1.9K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Bulimia Nervosa01:30

Bulimia Nervosa

61
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Assessment of the Gastrointestinal System II: Health Perception Pattern01:29

Assessment of the Gastrointestinal System II: Health Perception Pattern

87
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

科学领域:

  • 神经科学是一个神经科学.
  • 内分泌学 在内分泌学.
  • 心理学 心理学 心理学

背景情况:

  • COVID-19已与各种长期健康影响有关.
  • 饮食行为是一个复杂的过程,受荷尔蒙和神经信号的影响.
  • 对于COVID-19对食欲调节的影响仍然不完全理解.

研究的目的:

  • 调查COVID-19对饮食行为和食欲调节的持续影响.
  • 为了比较与食欲相关的荷尔蒙特征和大脑活动,在有和没有COVID-19病史的人群中比较.

主要方法:

  • 对来自两个组的55名成年人 (<50岁,没有超重/肥胖) 的横截面分析:非COVID-19 (n=27) 和COVID-19病史 (n=28).
  • 评估了饥饿,饮食行为 (TFEQ-18),血格林,神经Y (NPY) 和休息状态功能性MRI (fMRI).
  • 使用基于voxel的区域同质性 (ReHo) 和神经元同步性和连接性的中心度 (DC) 来分析大脑活动.

主要成果:

  • 与非COVID-19组相比,COVID-19组的血 ghrelin (197.5 vs. 67.1 pg/mL) 和NPY (128.0 vs. 84.5 pg/mL) 水平显著更高 (分别为p < 0.001和p = 0.005).与非COVID-19组相比,COVID-19组的血 ghrelin (197.5 vs. 67.1 pg/mL) 和NPY (128.0 vs. 84.5 pg/mL) 水平显著更高.
  • NPY水平与左舌环中的ReHo和DC正相关,这是参与食欲调节的区域.
  • 两组之间的认知克制,不受控制的饮食或情绪饮食得分没有显著差异 (p > 0.05).

结论:

  • 在COVID-19感染后长时间观察到食欲相关激素 (ghrelin,NPY) 的持续升高.
  • 增加的NPY水平与控制食欲的大脑区域神经活动的改变有关.
  • 尽管饮食行为模式稳定,但COVID-19可能会导致食欲神经内分泌调节的持久变化.
