概括
患有状细胞疾病 (SCD) 的高风险儿童在炎热的天气中面临更多的血管闭塞危机 (VOC) 紧急访问. 相反,更高的温度与该组急性胸部综合征 (ACS) 的紧急诊所数量较少相关.
科学领域:
- 环境健康 环境健康
- 儿科血液学 儿科血液学
- 气候变化的影响 气候变化的影响
背景情况:
- 状细胞疾病 (SCD) 导致儿童显著的发病率.
- 关于天气对儿科SCD并发症的影响的证据有限.
- 了解环境触发因素对于管理SCD至关重要.
研究的目的:
- 调查天气暴露和儿科SCD患者急性并发症急诊室 (ED) 访问之间的关联.
- 区分对血管闭塞危机 (VOC) 和急性胸部综合征 (ACS) 的影响.
- 评估低风险和高风险患者群体之间的风险差异.
主要方法:
- 美国儿童医院48,885例ED遭遇 (2015-2020年) 的回顾性案例交叉研究.
- 包括0-21岁的患有SCD的患者,经历了血管封闭性危机 (VOC) 或急性胸部综合征 (ACS).
- 分析了温度,热量指数 (HI) 和湿球温度 (WBGT) 和ED访问之间的关联,使用条件后勤回归,按风险分层 (低与高).
主要成果:
- 在高风险的儿科SCD患者中,在滞后的第3天升高的体温,HI和WBGT与VOC的ED访问的更高几率有关.
- 这些天气变量与高风险患者中ACSEDED访问率降低有关.
- 在低风险儿科SCD患者中没有观察到与天气相关的显著关联.
结论:
- 高温,HI和WBGT与高风险儿科SCD患者的VOC增加和ACSED访问减少相关.
- 这些发现突出了天气对SCD并发症的影响.
- 需要进一步的研究来确定气候变化中SCD并发症的环境风险因素.

Emerging Adulthood
676
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Hot Weather Concreting
313
Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing.
Mitigating the heat increase in concrete can be economically achieved by shading aggregate stockpiles to prevent heating from solar radiation,...

Cold Weather Concreting
374
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.

Hemodialysis II: Procedure and Complications
790
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Introduction Cardiac Emergencies
337
Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...
