Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.7K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Peripheral Artery Disease III: Interprofessional Care

11
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Venous Thrombosis III: Interprofessional Care

10
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Drugs that Stabilize Microtubules01:15

Drugs that Stabilize Microtubules

2.1K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
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...

Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

6.3K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Area of Science:

  • Cardiology
  • Vascular Biology
  • Internal Medicine

Background:

  • Coronary microvascular dysfunction (CMD) is a significant cause of myocardial ischemia without obstructive coronary artery disease.
  • CMD presents diagnostic and therapeutic challenges due to limited mechanistic understanding and targeted treatments.
  • The coronary microcirculation's inability to meet myocardial oxygen demand characterizes CMD.

Purpose of the Study:

  • To review current evidence for managing coronary microvascular dysfunction.
  • To explore the role of invasive assessment in stratifying antianginal therapies.
  • To provide an evidence-based appraisal of CMD management strategies.

Main Methods:

  • Systematic review of existing literature on CMD diagnosis and management.
  • Appraisal of evidence for cardiovascular risk factor modification.
  • Evaluation of antianginal therapies and atherosclerosis treatments in the context of CMD.

Main Results:

  • Invasive assessment of coronary microcirculation aids in stratifying antianginal therapies.
  • Management strategies include addressing cardiovascular risks, optimizing antianginal treatments, and managing atherosclerosis.
  • Personalized therapy based on microvascular assessment shows potential for improved patient outcomes.

Conclusions:

  • Stratified antianginal therapy guided by invasive coronary microcirculation assessment is crucial for managing CMD.
  • Comprehensive management involves treating cardiovascular risk factors, atherosclerosis, and employing targeted antianginal treatments.
  • Further research into CMD mechanisms is needed to develop more effective targeted therapies.
