Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.9K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Drug Therapy

370
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Development of Antibiotic Resistance01:30

Development of Antibiotic Resistance

1.8K
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...

Psychosis: Goals of Pharmacotherapy

651
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Elements Crucial for Effective Psychotherapy01:25

Elements Crucial for Effective Psychotherapy

412
Research has highlighted several critical factors that influence the effectiveness of psychotherapy, such as the therapeutic alliance, the therapist, and the client.
The Therapeutic Alliance
The therapeutic alliance refers to the relationship between the therapist and the client. The alliance strengthens when the therapist and the client engage in a nurturing, supportive, trusting, empathetic, and respectful relationship, improving therapeutic outcomes. Therapists must monitor this relationship...

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Lung adenocarcinoma treatment has been transformed by identifying driver mutations.
  • Testing for epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and ROS1 alterations is standard for lung cancer.
  • Numerous other lung cancer driver mutations have expanded therapeutic strategies.

Purpose of the Study:

  • To review mechanisms of resistance to targeted lung cancer therapies.
  • To discuss emerging treatment options for overcoming resistance.
  • To briefly touch upon chemotherapy resistance and immune checkpoint inhibitors.

Main Methods:

  • Literature review focusing on resistance mechanisms in lung cancer.
  • Analysis of current and emerging therapeutic strategies.
  • Discussion of underlying biological processes of resistance.

Main Results:

  • Targeted treatments yield rapid, durable responses but are eventually overcome by resistance.
  • Understanding resistance mechanisms enables the development of novel therapeutic approaches.
  • Chemotherapy and immune checkpoint inhibitors represent alternative or complementary strategies.

Conclusions:

  • Resistance to targeted lung cancer therapies is inevitable and necessitates continuous research.
  • Advances in understanding resistance mechanisms are crucial for improving patient outcomes.
  • A multi-faceted approach combining targeted therapy, chemotherapy, and immunotherapy is essential.
