Peripheral Artery Disease IV: Nursing Management

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...
Diabetic Foot Ulcer01:31

Diabetic Foot Ulcer

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Diabetic Neuropathy01:22

Diabetic Neuropathy

DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...

科学领域:

  • 医疗信息学 医疗信息学
  • 计算生物学 计算生物学
  • 糖尿病学 糖尿病学

背景情况:

  • 糖尿病足 (DFU) 是一种重要的糖尿病并发症,影响生存和生活质量.
  • 目前的DFU分类系统缺乏个别预测能力.
  • 机器学习 (ML) 模型被提出作为改善DFU特征和预测的解决方案.

研究的目的:

  • 系统地识别和评估ML模型的证据,预测DFU患者的临床结果.
  • 评估现有的基于ML的DFU预测模型的预测准确度和局限性.

主要方法:

  • 在主要数据库 (MEDLINE,Scopus,Web of Science,IEEE Xplore) 进行全面的文献搜索,截至2023年7月.
  • 包括至少80%的成年DFU人口的前级分析研究.
  • 使用既有工具 (QIPS,PROBAST) 进行独立的文献选,数据提取和偏差风险评估.

主要成果:

  • 十一项研究 (13篇论文) 分析了55个ML模型,预测伤口愈合,截肢或死亡率.
  • 模型主要使用临床数据和随机森林,大多数实现接收器操作特征曲线 (AUROC) 下面面积≥0.8.8.
  • 所有纳入的研究都显示出偏差的高风险,原因是定义不一致,样本规模小,数据处理不充分.

结论:

  • 几种ML模型显示了对DFU结果的良好的区分能力.
  • 广泛的临床应用受到专注于模型开发,缺乏外部验证和使用无法解释的技术的阻碍.
  • 未来的研究应该优先考虑对DFU护理的外部验证和可解释的ML模型的开发.
