概括

在血液感染 (BSI) 中,较短的阳性时间 (TTP) 表明疾病严重程度和死亡风险增加. 这种非线性关联解释了以前的相互矛盾的结果,并突出了TTP.

科学领域:

医学微生物学医学微生物学
传染性疾病传染性疾病
临床病理学临床病理学

背景情况:

时间到阳性 (TTP) 是血液感染 (BSI) 的潜在预后标志物.
之前关于TTP作为预后指标的研究已经产生了相互矛盾的结果.
TTP与疾病严重程度之间的非线性关系需要进一步研究.

研究的目的:

探索TTP与血液感染中的疾病严重程度之间的关联.
利用非线性模型来分析TTP和临床结果之间的关系.
为了澄清在BSI中TTP的预后价值.

主要方法:

在瑞典南部 (2021-2023) 进行了一项基于人口的回顾性研究.
分析了来自12,585个血液感染病例的数据.
使用非线性回归模型来评估TTP,疾病严重程度标志物和患者结果之间的关联.

主要成果:

较短的TTP显著与较高的死亡率和重症监护入院风险增加有关.
死亡率在较短的TTP时呈指数级增长,在3小时内达到30%.
TTP与疾病严重性标志物 (例如乳酸) 之间的关联和结果是非线性的.

结论:

阳性反应的时间是疾病严重程度和血液感染的预后的有价值指标.
确定了TTP与结果的指数关联,为之前的相互矛盾的发现提供了生物学解释.
需要进一步的研究来确定TTP在管理BSI中的临床实用性.

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Factors Affecting Illness

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Bias in Epidemiological Studies

Bias in Epidemiological Studies

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:
