概括
严重的热浪可能会加剧早产率 (PTB) 的种族差异. 在1995年芝加哥热浪之后,非西班牙裔黑人出生时PTB发病率增加,但非西班牙裔白人出生时没有增加.
科学领域:
- 环境健康 环境健康
- 生殖健康 生殖健康
- 流行病学 流行病学
背景情况:
- 极端高温事件的频率和强度正在增加.
- 过早分娩 (PTB) 是一个重要的公共卫生问题,已知种族差异.
- 严重的热浪对跨种族群体PTB发病率的影响需要进一步调查.
研究的目的:
- 评估1995年芝加哥热浪后非西班牙裔 (NH) 黑人和NH白人分娩中早产 (PTB) 发病率的变化是否有所不同.
- 调查因暴露于极端高温而导致PTB种族差异可能加剧的情况.
主要方法:
- 生态研究设计使用国家生命统计档案数据 (1990-1996).
- 计算库克县,芝加哥每月PTB发病率的平均值.
- 时间序列建模与合成对照NH黑色和NH白色出生,包括SES分析.
主要成果:
- 平均每月PTB发病率为NH黑人出生的18.6%,与NH白人出生的7.8%相比 (1990-1996).
- 在1995年8月至1996年1月的NH黑人出生中,与预期的比率相比,PTB发病率增加了16.7%.
- 在NH白胎中没有注意到PTB发病率的显著增加;在低SESNH黑胎中发生了类似的增加.
结论:
- 严重的热浪可能会导致早产率的种族差异增加.
- 可能需要有针对性的干预措施来减轻极端高温对弱势群体的影响,并减少PTB差异.

Teratogenicity
2.5K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Regression Toward the Mean
6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Homeostatic Imbalances in Body Temperature
153
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Bias in Epidemiological Studies
343
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Pathophysiology of Diabetes
980
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
