概括
身体质量指数 (BMI) 的极端值,而不是其他身体组成指标,与心脏移植 (HT) 后更高的再入院和感染率相关. 目前的BMI指南可能有助于识别有风险的HT患者.
科学领域:
- 心脏病学 心脏病学
- 移植医学 移植医学
- 身体组成分析 身体成分分析
背景情况:
- 目前的心脏移植 (HT) 列表指南使用体重指数 (BMI) <35 kg/m2.
- 支持这一BMI值的证据是混合的.
- 对于HT后的结果,特定身体成分测量的预测价值尚未得到充分确立.
研究的目的:
- 评估特定的身体组成指标是否预测心脏移植 (HT) 后的结果.
- 将BMI的预测准确度与HT后结果的其他身体组成措施进行比较.
主要方法:
- 对104名接受HT (2014-2019) 患者进行腹部CT扫描的回顾性研究.
- 使用Slice-O-Matic软件进行组织表征,用于BMI,脂肪质量指数 (FMI),内脏脂肪组织与皮下脂肪组织的比率 (VAT/SAT),无脂肪质量指数 (FFMI) 和骨肌肉指数 (SMI).
- 后勤回归分析评估了体型组合三位体与1年死亡率,再入院,初级移植功能障碍,停留时间,感染和功能衰竭之间的关联.
主要成果:
- 最高和最低的BMI三位数与1年重入院 (p=0.01) 和感染 (p=0.02) 的风险增加显著相关.
- 脂肪质量指数 (FMI),增值税/SAT比率,FFMI和SMI与任何研究结果都没有显著关联.

00:55Composite Bodies
1.4K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

01:29Composition of Body Fluids
2.5K
Water functions as a solvent accommodating various solutes, which can be categorized under electrolytes and non-electrolytes. Non-electrolytes are usually held together by covalent bonds, restricting them from dissociating in solution, thereby leading to a lack of electrically charged components upon dissolving in water. They are predominantly organic molecules, such as glucose, creatinine, and urea. Electrolytes, on the other hand, are compounds that can break down into ions in water.

01:13Equipments Used to Measure Body Temperature
1.8K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

02:18Alternative RNA Splicing
25.1K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

02:24Predicting Reaction Outcomes
10.8K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...
