概括
2017年EULAR/ACR肌肉炎标准错误分类了超过一半的遗传性肌肉病患者,突出了诊断方面的挑战. 临床表现和活检结果的相似性导致炎症性肌肉病的误诊.
科学领域:
- 神经学 神经学
- 类风湿病学 类风湿病学
- 遗传学 遗传学 是一个
背景情况:
- 遗传性肌肉病变和异常性炎症性肌肉病变 (肌肉炎) 呈现重叠的临床特征,使准确的诊断变得复杂.
- 2017年欧洲风湿病学协会联盟/美国风湿病学学院 (EULAR/ACR) 的分类标准旨在通过概率得分来改善肌炎诊断.
研究的目的:
- 评估2017年EULAR/ACR分类标准的准确性,以区分肌炎与遗传性肌病.
- 识别特定的诊断陷和导致错误分类的误导因素.
主要方法:
- 对105名遗传确认遗传性肌肉病变的患者进行了回顾性分析,包括肌肉性缩症 (DM1,DM2),骨头骨肌肉缩症 (FSHD),四肢腰围肌肉缩症 (LGMD) 和杜氏/贝克尔肌肉缩症 (DMD/BMD).
- 2017年EULAR/ACR标准应用于患者数据,以评估错误分类率和分析促成因素.
主要成果:
- 有相当一部分遗传性肌肉病患者被错误地归类为肌肉炎患者:50% (DM1),47.8% (DM2),25% (FSHD),35.3% (LGMD) 和36.4% (DMD). 贝克尔肌肉发育不良 (BMD) 显示0%的错误分类.
- 该队列的标准的整体特异性为63.8%.
- 包括体肌肉炎是最常见的错误分类亚型. 靠近肌肉的软弱,肌酸激酶 (CK) 的升高,周围肌缩以及活检上的内膜透被确定为误导性特征.
结论:
- 2017年EULAR/ACR标准在区分炎症性肌肉病与遗传性肌肉病方面表现出有限的特异性,原因是临床和诊断发现重叠.
- 在LGMD,DM1和DM2等遗传性肌肉病中,晚期发病的表现会导致诊断挑战和潜在的错误分类.

4.2K
Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.

42.9K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

4.0K
A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.

01:10Documentation of Nursing Diagnosis
1.8K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Thermodynamics of a Redox Reaction
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
