概括
暴露于高热应激的工人面临损伤的风险增加,超过65%的工人超过了安全温度限制. 这种职业热暴露显著提高了功能减弱 (eGFR) 的可能性.
科学领域:
- 职业健康 职业健康 职业健康
- 环境健康 环境健康
- 腎臟病學 (nephrology) 是一種醫學專業.
背景情况:
- 全球气温上升加剧了工人的热应激 (HS),增加了对与热有关的疾病的易感性.
- 原因不明的慢性病 (CKDu) 在炎热气候地区的非农业工人中越来越令人担忧.
- 果仁工人尤其面临风险,因为脱水,热压力和体力疲劳会损害脏健康.
研究的目的:
- 调查果工人中职业热量暴露与功能之间的关联.
- 评估与热暴露水平相关的热应变指标和泌尿器官症状的流行程度.
- 确定高热暴露工人估计淋巴细胞过率 (eGFR) 降低的几率.
主要方法:
- 在泰米尔纳德邦Cuddalore的2020-2021年研究中,评估了262名果仁工人.
- 湿球球体温度 (WBGT) 和美国政府工业卫生师会议标准评估了热量暴露和工作量.
- 测量了热应变指标 (HSI),包括耳温度,汗流率,尿液特异性重量和血清肌素;计算了eGFR.
主要成果:
- 超过65%的工人经历过WBGT超过安全值 (平均WBGT30.4°C±1.8°C).
- 95%的暴露于热量的工人至少表现出一种生理热应变指标.
- 暴露于高热量的工人患EGFR<90毫升/分钟/1.73米2的概率高3.5倍,尿路器官症状的风险高7.7倍.
结论:
- 持续的职业热力压力会对果仁工人的功能产生负面影响,由较低的EGFR表示.
- 需要进一步的研究来了解慢性热暴露对的长期影响.
- 实施工作场所冷却解决方案对于减轻热应激和保护脏健康至关重要.

01:21External Anatomy of the Kidney

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
