概括

在Lejeune海军基地营地饮用水中暴露于挥发性有机化合物 (VOC) 可能会加速帕金森病 (PD) 的进展. 与未暴露的个体相比,暴露于VOC的个体表现出更快的精神病发作,骨折和跌倒.

科学领域:

环境健康环境健康
神经科学是一个神经科学.
流行病学流行病学

背景情况:

以前的研究表明,由于受污染的水,Lejeune海军基地营地的服务人员患帕金森病 (PD) 的风险增加.
挥发性有机化合物 (VOC) 对PD进展的影响在很大程度上尚未研究.

研究的目的:

调查在Lejeune营地饮用水中的VOC暴露是否与加速PD进展有关.

主要方法:

分析了来自Lejeune营 (1975-1985) 的172,128名海军陆战队员的队列.
在VA和医疗保险数据库 (2000-2021) 中确定了PD患者.
暴露于VOCs被使用ATSDR估计分类;生存分析 (Kaplan-Meier,Cox回归) 将暴露和未暴露组之间的进展结果 (精神病,骨折,跌倒,死亡) 进行比较.

主要成果:

在270名PD患者中,177人 (65.6%) 暴露于VOC,中位数暴露超过了允许水平的50倍以上.
暴露的个体经历的精神病 (HR 2.19),骨折 (HR 2.44) 和跌倒 (HR 2.64) 的时间显著缩短.
观察到达死亡时间的剂量-反应关系 (P趋势=0.032);没有发现死亡时间的差异.

结论:

饮用水中的三乙烯和其他VOCs可能会加速PD的进展,表现为早期发病的精神病,骨折和跌倒.
这些发现表明环境暴露对神经退行性疾病进展的长期影响.

关键词:

帕金森病的疾病.风险暴露风险暴露风险暴露这是一个渐进的过程.溶剂溶剂的使用方法三乙烯是一种三乙烯.

Parkinson's Disease: Overview

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Lysosomal Hydrolases

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
