- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
- 腎臟病學 (nephrology) 是一種醫學專業.
背景情况:
- 固体器官移植 (SOT) 接受者面临肺囊性肺炎 (PCP) 的风险增加.
- 与其他非HIV免疫受损人群相比,在SOT接受者中PCP的临床特征和结果尚不清楚.
- PCP是免疫功能低下个体的重大机会性感染.
研究的目的:
- 在固体器官移植 (SOT) 接受者与其他非艾滋病毒免疫受损患者中比较肺囊炎肺炎 (PCP) 的临床表型和结果.
- 评估90天死亡率,30天死亡率和需要透析的新功能衰竭作为关键结果.
- 为了确定影响PCP结果的因素,在不同的免疫受损群体.
主要方法:
- 一项多中心的回顾性队列研究,涉及2017年至2025年期间已被证明或可能患有PCP的成年人.
- 95名SOT接受者与588名非SOT,非HIV免疫受损患者的比较.
- 使用反向概率加权 (IPW) 和获利量化来调整基线差异并分析结果.
主要成果:
- 在调整后,SOT接受者与非SOT患者相比,90天死亡率 (HR:0.32) 和30天死亡率 (HR:0.35) 显著降低.
- 尽管存活率有所改善,但SOT接受者患新发功能衰竭需要透析的几率更高 (OR: 1.62).
- 未经调整的分析也表明,SOT接受者的死亡率较低,但功能衰竭率更高.
结论:
- 与其他非艾滋病毒免疫受损个体相比,PCP固体器官移植接受者表现出更好的短期和中期存活率.
- 在SOT接受者中需要透析的功能衰竭的更高发病率值得注意.
- 需要进一步的研究来了解影响PCP结果的移植相关因素.

Metallic Solids
20.5K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

Structures of Solids
17.5K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Pneumonia I: Introduction
760
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Network Covalent Solids
16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
