Tumor Progression

7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Prediction Intervals

3.3K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.7K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

End Point Prediction: Gran Plot01:07

End Point Prediction: Gran Plot

1.2K
A Gran plot is used to predict the equivalence volume or endpoint of a potentiometric or acid-base titration without reaching the endpoint. Typically, titration data is collected as a function of the titrant's volume up to a point less than the equivalence volume and then transformed into a linear format. The straight line is extended to the x-axis, indicating the necessary titrant volume to achieve the equivalence point.
For potentiometric titration, the Gran plot is created by plotting...

Sensitivity, Specificity, and Predicted Value

1.2K
In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.
Sensitivity is the...

Area of Science:

  • Nephrology
  • Public Health
  • Biostatistics

Background:

  • Taiwan faces a high prevalence of chronic kidney disease (CKD) and the world's highest incidence of end-stage renal disease (ESRD).
  • Predicting CKD progression to ESRD is challenging due to numerous risk factors and the lack of highly accurate predictive models.
  • Existing models lack sufficient explanatory power for predicting dialysis risk in Taiwanese CKD patients.

Purpose of the Study:

  • To develop an optimal prediction model for CKD progression to dialysis in Taiwan.
  • To identify key risk factors with high explanatory power for predicting ESRD.
  • To improve risk stratification for CKD patients in Taiwan.

Main Methods:

  • Retrospective cohort study using data from a national health insurance program (2006-2013).
  • Analysis of demographic variables, medical history, and blood biochemical values from CKD patients.
  • Application of the Cox proportional hazard model and likelihood ratios (LR) to identify the most predictive model.

Main Results:

  • The study analyzed 1549 CKD patients, with 1017 progressing to dialysis.
  • The optimal prediction model identified age (HR 0.95), creatinine (HR 1.03), urea nitrogen (HR 1.18), and comorbid systemic diabetes (HR 1.65) as significant predictors.
  • This model demonstrates strong explanatory power using minimal variables.

Conclusions:

  • A validated prediction model for CKD progression to dialysis has been established for the Taiwanese population.
  • The model utilizes readily available clinical data (age, creatinine, urea nitrogen, diabetes) for accurate risk assessment.
  • This tool can aid clinicians in predicting dialysis risk and potentially inform preventive strategies.
