概括
婴儿中轻度蛋白质能量营养不良 (PEM) 显示出明显的性别特异性代谢变化. 女孩表现出较高的代谢压力,而男孩表现出改变的能量基质,表明潜在的症.
科学领域:
- 儿科 儿科 儿科
- 生物化学 生物化学
- 营养科学 营养科学
背景情况:
- 蛋白质能量营养不良 (PEM) 仍然是一个全球性问题,内源性因素有助于其持续存在.
- 轻度PEM经常被忽视,但幼儿营养不良可能会导致终身健康后果.
- PEM的性别特异性病原体需要进一步研究.
研究的目的:
- 为了研究经历轻度PEM的初始阶段的婴儿的性别特异性血液代谢概况.
- 为了确定早期的生化标志物,区分男性和女性婴儿之间对PEM的代谢反应.
主要方法:
- 检查了38名婴儿 (1-12个月) 具有I级PEM和30名健康对照.
- 进行了全面的血液检查,分析了总蛋白质,白蛋白,血红蛋白,转蛋白,尿素,肌,葡萄糖,乳酸,酸盐和甘油三.
- 评估了酶活性,包括乳酸脱酶,氨酸转移酶,亚斯巴酸转移酶和肌酸化酶.
主要成果:
- 在PEM婴儿和对照组之间,总蛋白质,白蛋白,血红蛋白或转激素没有显著差异.
- 在PEM婴儿中尿素含量升高和肌素水平显著升高,在女孩中特别明显 (2.5倍),表明了代谢性压力.
- 患有PEM的男孩表现出葡萄糖和甘油三降低,酸盐增加,乳酸/酸盐比率升高,这表明症.
- 患有PEM的女孩表现出稳定的甘油三,但乳酸/酸盐比率显著增加,这表明潜在的乳酸化.
结论:
- 婴儿中轻度PEM呈现出明显的性别特异性代谢变化.
- 男性婴儿显示代谢转向症,而女性婴儿显示更强烈的代谢应激和倾向于乳糖酸症.
- 这些发现强调了在儿童PEM的早期诊断和管理中考虑性别的重要性.

Overview of Protein Metabolism
788
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Inborn Errors of Metabolism
140
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Sex-linked Disorders
101.5K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Adrenal Gland Disorders
1.4K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Anorexia Nervosa
47
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.

Bone Disorders
3.4K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
