Combination Therapies and Personalized Medicine

5.0K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Clinical Trials: Overview

3.1K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Issues And Trends In Healthcare Delivery System

5.8K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Clinical Trials

7.0K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Nursing Ethical Principles II01:27

Nursing Ethical Principles II

1.1K
Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.
Consider the following scenario, which illustrates how these principles are applied in the care of Mr. John, a fifty-year-old teacher diagnosed with metastatic liver cancer.
Initially, Mr. John's...

Area of Science:

  • Health Informatics
  • Cryptography
  • Clinical Decision Support

Background:

  • HIV treatment prescription is complex, with Clinical Decision Support Systems (CDSS) aiding clinicians.
  • Current CDSS for HIV lack insights from past patient treatment data due to privacy constraints.
  • Patient records hold valuable treatment knowledge but are restricted by privacy and confidentiality rules.

Purpose of the Study:

  • To develop a method for extracting treatment effectiveness measures from patient records for HIV CDSS.
  • To enhance HIV treatment decision support by utilizing collective patient treatment knowledge.
  • To ensure patient privacy and data confidentiality during knowledge extraction.

Main Methods:

  • Defined a treatment effectiveness measure, specifically average time-to-treatment-failure.
  • Developed a method using secure Multiparty Computation (MPC) to extract this measure.
  • Employed advanced cryptographic techniques to preserve patient record privacy and decision confidentiality.

Main Results:

  • Successfully computed an HIV treatment effectiveness measure (average time-to-treatment-failure) while maintaining privacy.
  • The developed solution demonstrated good efficiency in experimental results.
  • A query on a realistic dataset was processed within 24 minutes, indicating practical viability.

Conclusions:

  • Presents a novel and efficient approach for HIV clinical decision support systems.
  • Harnesses insights from patient treatment data without compromising privacy or confidentiality.
  • Enhances CDSS capabilities by securely integrating real-world treatment outcomes.
