Whether it’s your wife or husband or child, or a relative or close friend you are caring for, it is paramount that you become the best caregiver possible for your loved one. As a caregiver for my wife Jacqui during her brave journey to beat leukemia (acute myelogenous leukemia), here is what I learned and can share as I honor and applaud caregivers everywhere.
Biomarker Bulletin is an occasionally recurring update of news focused on biomarkers aggregated at BiomarkerCommons.org. Biomarkers are physical, functional or biochemical indicators of normal physiological or disease processes. The individualization of disease management — personalized medicine — is dependent on developing biomarkers that promote specific clinical domains, including early detection, risk, diagnosis, prognosis and predicted response to therapy.
Diagnostics used to select patients for treatment with a particular therapeutic or determine what and/or how treatment will be administered have been termed companion diagnostics. Companion diagnostics hold great promise for personalized medicine. A companion diagnostic is a biomarker(s) used in a specific context that provides biological and/or clinical information that enables better decision making about the development and use of a potential therapeutic. Given the significance of companion diagnostics, I’m proud to announce Biomarker Commons’ first media partnership with the 4th World Companion Diagnostics Summit.
Personalized medicine is a term used in science and medicine that holds significant promise of administering medicines specifically tailored to an individual’s genome or metabolism. However, an editorial published yesterday in the Canadian Medical Association Journal (CMAJ) suggests that the term creates an image for the public that is completely opposite of science and technology and sets up unrealistic expectations.
Regulators in the U.S. and Europe have each posted requests for public comment on issues affecting the development of medicines by drug companies.
The U.S. Food and Drug Administration (FDA) has issued new guidelines on biomarkers related to drug or biotechnology product development. The guidance was developed within the Efficacy Working Group of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH).
In response to facial expression of emotional, a similar pattern of brain activity is observed in both people with autism and their unaffected siblings. Researchers from the University of Cambridge recently used functional magnetic resonance imaging (fMRI), a specialized MRI scan used to measure the change in blood flow related to neural activity in the brain, to show that reduced activity in areas of the brain associated with empathy and face processing is a candidate biomarker for familial risk of autism. The findings were published online recently in the journal Translational Psychiatry.
Neurofibromatosis type 1 is a genetic condition that can cause tumors to form on nerves under the skin. Since these tumors can become malignant, it is important to monitor their growth closely and detect signs of malignant transformation as early as possible. However, the only way to currently detect them is with an MRI scan. New research published in BioMed Central’s open access journal BMC Medicine shows that a simple blood test for the protein melanoma-inhibitory activity (MIA) may be used to indicate the presence of neurofibromas even if they cannot be seen [1].
The first high-resolution structural connection map of the human cerebral cortex was published earlier this month in the journal PLoS Biology. The study reveals regions that are highly connected and central, forming a structural core network [1]. Intriguingly, this core network consists of many areas that are more active when we’re at rest than when we’re engaged in a task that requires concentration.
The American Society of Clinical Oncology (ASCO) recently published its third annual Clinical Cancer Advances report, Clinical Cancer Advances 2007: Major Research Advances in Cancer Treatment, Prevention and Screening [1]. It was developed under the guidance of a 21-person editorial board consisting of leading oncologists and cancer specialists, including specialty editors for each of the disease-specific and issue-specific sections. The report highlights 6 major advances in cancer research in 2007 and describes an additional 18 other findings of significant importance, demonstrating the pace of progress being made in cancer prevention, screening, treatment, epidemiology and survivorship.
