要旨

Objective:

This study aims to identify risk factors and develop a predictive model for restenosis after ultrasound-guided percutaneous transluminal angioplasty (PTA) for arteriovenous fistula (AVF) stenosis.

Methods:

A total of 100 patients undergoing PTA were categorized into restenosis (n = 39) and non-restenosis (n = 61) groups based on 12-month follow-up. Multivariable logistic regression identified independent risk factors, and a nomogram was constructed. Model performance was assessed using ROC analysis, calibration curves, and decision curve analysis (DCA).

Results:

Diabetes (odds ratio [OR] = 1.94), type I stenosis (OR = 3.49), severe AVF stenosis (OR = 2.37), AVF functional time < 6 months (OR = 3.17), vascular calcification (OR = 4.34), and elevated High-Sensitivity C-Reactive Protein (OR = 2.82) were independent risk factors (all p < 0.05). The predictive model demonstrated good discrimination (area under the curve [AUC] = 0.820) and calibration (p = 0.3575). DCA confirmed clinical utility.

Conclusion:

Key risk factors for restenosis were identified, and the predictive model showed strong performance, aiding clinical decision-making.

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 Influencing Heart Rate

Factors Influencing Heart Rate

The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Factors Influencing the Rate of Chemical Reactions

Factors Influencing the Rate of Chemical Reactions

A variety of factors influence the rate of chemical reactions. For a chemical reaction to happen, atoms must collide with enough energy to overcome the repulsion between their electrons. This energy is called activation energy. Factors influencing the rate of reaction either lower the activation energy or increase the likelihood of a successful collision.
Concentration and Pressure:
The more particles present within a given space, the more likely those particles are to bump into one another....

Factors Affecting Drug Distribution: Organ Perfusion Rate

Factors Affecting Drug Distribution: Organ Perfusion Rate

Drug distribution within the body is a complex process influenced by several factors, including perfusion rate, the rate at which the bloodstream transports drugs to tissue. This limitation becomes particularly significant when dealing with highly lipophilic drugs. In such cases, the rate at which the drug can move across membranes is crucial, and if the membrane is highly permeable to the drug, distribution becomes rate-limited by perfusion.
Perfusion rate-limited distribution relies on the...

Relative Risk

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Transcription Factors

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
