ScienceDaily (Mar. 8, 2012) UT Southwestern Medical Center investigators have identified a genetic manipulation that increases the development of neurons in the brain during aging and enhances the effect of antidepressant drugs.

The research finds that deleting the Nf1 gene in mice results in long-lasting improvements in neurogenesis, which in turn makes those in the test group more sensitive to the effects of antidepressants.

"The significant implication of this work is that enhancing neurogenesis sensitizes mice to antidepressants -- meaning they needed lower doses of the drugs to affect 'mood' -- and also appears to have anti-depressive and anti-anxiety effects of its own that continue over time," said Dr. Luis Parada, director of the Kent Waldrep Center for Basic Research on Nerve Growth and Regeneration and senior author of the study published in The Journal of Neuroscience.

Just as in people, mice produce new neurons throughout adulthood, although the rate declines with age and stress, said Dr. Parada, chairman of developmental biology at UT Southwestern. Studies have shown that learning, exercise, electroconvulsive therapy and some antidepressants can increase neurogenesis. The steps in the process are well known but the cellular mechanisms behind those steps are not.

"In neurogenesis, stem cells in the brain's hippocampus give rise to neuronal precursor cells that eventually become young neurons, which continue on to become full-fledged neurons that integrate into the brain's synapses," said Dr. Parada, an elected member of the National Academy of Sciences, its Institute of Medicine, and the American Academy of Arts and Sciences.

The researchers used a sophisticated process to delete the gene that codes for the Nf1 protein only in the brains of mice, while production in other tissues continued normally. After showing that mice lacking Nf1 protein in the brain had greater neurogenesis than controls, the researchers administered behavioral tests designed to mimic situations that would spark a subdued mood or anxiety, such as observing grooming behavior in response to a small splash of sugar water.

The researchers found that the test group mice formed more neurons over time compared to controls, and that young mice lacking the Nf1 protein required much lower amounts of anti-depressants to counteract the effects of stress. Behavioral differences between the groups persisted at three months, six months and nine months. "Older mice lacking the protein responded as if they had been taking antidepressants all their lives," said Dr. Parada.

"In summary, this work suggests that activating neural precursor cells could directly improve depression- and anxiety-like behaviors, and it provides a proof-of-principle regarding the feasibility of regulating behavior via direct manipulation of adult neurogenesis," Dr. Parada said.

Dr. Parada's laboratory has published a series of studies that link the Nf1 gene -- best known for mutations that cause tumors to grow around nerves -- to wide-ranging effects in several major tissues. For instance, in one study researchers identified ways that the body's immune system promotes the growth of tumors, and in another study, they described how loss of the Nf1 protein in the circulatory system leads to hypertension and congenital heart disease.

The current study's lead author is former graduate student Dr. Yun Li, now a postdoctoral researcher at the Massachusetts Institute of Technology. Other co-authors include Yanjiao Li, a research associate of developmental biology, Dr. Rene McKay, assistant professor of developmental biology, both of UT Southwestern, and Dr. Dieter Riethmacher of the University of Southampton in the United Kingdom.

Genetic manipulation boosts growth of brain cells linked to learning, enhances effects of antidepressants

The New Medicine Service (NMS) offered by Engalnd’s  NHS community pharmacies came into effect since 1st October 2011. NMS is a patient adherene service and focuses on patients with long term conditions that have been prescribed new medicines.

It is hoped that NMS will lead to the following outcomes:

• improve medicines adherence
• increase patient engagement with their condition and medicines, which will support them in making decisions about their treatment and self management
• reduce medicines wastage
• reduce hospital admissions due to adverse events associated with medicines
• increase reporting of medicine adverse reactions by pharmacists and patients
• positive patient assessments
• provide evidence base on the effectiveness of the service
• enable the development of outcome and/or quality measures for community pharmacy

But the Service since launch has seen severe criticism from pharmacists’ over several issues, especially how the pharmacist is re-imbursed for the providing the service which also involved patient counselling.

The answer perhaps can be found by applying predictive analytics to identify patients who are more likely to deviate or other likely to exhibit non-compliance in adhering to the prescription.

Express Scripts has developed a set of proprietary computer models that predict, up to a year in advance, which patients are at risk of not following through on their prescribed drug therapy. details

FICO an analytics service provider also provides medication adherence ranking based on predictive analytics details

Companies on the forward edge are putting a heavy emphasis on digital in their commercial models — but how can mobile technologies assist pharmaceutical and biotech firms in this transition?   Tablets to support the sales force – While sales forces are shrinking, they still play a vital role in educating prescribers on new medications. The pharma industry, taking the lead of companies like GSK, is starting to incent sales reps based on quality of service versus amount of sales (read more here in the WSJ). One of the tools that is helping deliver better service is the tablet. Reps with an iPad can deliver more interactive and engaging product information, capture signatures for compliance and make the most of a few quick minutes with a doctor in the time it would take a laptop to boot up.   Online and mobile drug sampling programs – Companies now have the ability to leverage PDMA-compliant mobile apps and websites that allow physicians to request free product samples that they can distribute to their patients to gauge efficacy and assist with adherence. Because the Internet never sleeps, physicians can do this no matter what shifts they are working, independent of time zone or location, 24 hours a day.   Direct-to-HCP mobile advertising – It used to be that most online and mobile advertisements for drugs were placed only in industry magazines, blogs and online communities geared toward healthcare professionals and general consumer websites. We see this changing, with emergence of mobile networks focused on healthcare such as Tomorrow Networks, which is comprised of more than 50 medical apps. Pharma companies can now buy ad placements in mobile apps made exclusively for physicians and other healthcare professionals. A physician can be looking up treatment information at the point of care and see an ad for a medication that is relevant to their patient’s ailment. That’s incredibly powerful for the physician and advantageous for the advertiser.   mDetails – Physicians want to learn about the best drugs and treatments for their patients. mDetails are multimedia mobile product presentations that provide information about drugs in a way that allows physicians to absorb detailed information at their own pace — and in their own time. Because mDetails are distributed on smartphones – it lets physicians fit pharma product education into ‘found time’ at any point during their day that’s convenient for them.   By employing a multi-channel approach and by helping healthcare professionals do their jobs better instead of just selling to them, pharmaceutical companies can reach their target audiences and develop deeper value-based relationships. The aforementioned examples are just a few of the ways that pharmaceutical companies can leverage the ever-growing mobile channel; there are many more evolving every day.
