This population-based study examined cobalamin status and incident fractures in elderly men (n = 790) with an average follow-up of 5.9 years. This study aimed to determine whether serum cobalamins or holotranscobalamin (holoTC: the metabolic active cobalamin) predict incident fractures. Men participating in the Gothenburg part of the population-based Osteoporotic Fracturs in Men (MrOS) Sweden cohort and without ongoing vitamin B medication were included in the study (age range 70- 81 years). The results showed that 110 men sustained X-ray verified fractures including 45 men with clinical vertebral fractures. The risk of fracture (adjusted for age, smoking, BMI, BMD, falls, prevalent fracture, tHcy, cystatin C, 25-OH-vitamin D, intake of calcium, and physical activity, increased per each standard deviation decrease in cobalamins (HR 1.38; 95 % CI, 1.11-1.72) and holoTC (HR, 1.26; 95 % CI, 1.03-1.54), respectively. Men in the lowest quartile of cobalamins and holoTC had an increased risk of all fracture (cobalamins, HR = 1.67 (95 % CI, 1.06-2.62); holoTC, HR = 1.74 (95 % CI, 1.12-2.69)). No associations between folate or tHcy and incident fractures were seen. The authors conclude that low levels of holoTC and cobalamins predict incident fracture in elderly men.

Vitamin D may help with Multiple Sclerosis
Multiple Sclerosis (MS) is associated with vitamin D deficiency. This study examined some of the immunological effects of vitamin D on the prevention of MS in a mouse model. Pharmacologic targeting of T helper (TH) cell trafficking poses an attractive opportunity for amelioration of autoimmune diseases. The bioactive form of vitamin D, 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], has been shown to prevent experimental autoimmune encephalomyelitis, a mouse model of MS, via an incompletely understood mechanism. In this study, the authors systematically examined 1,25(OH)2D3 effects on TH cells during their migration from the lymph nodes to the CNS. The results showed that myelin-reactive TH cells are successfully generated in the presence of 1,25(OH)2D3, secrete proinflammatory cytokines, and do not preferentially differentiate into suppressor T cells. These cells are able to leave the lymph node, enter the peripheral circulation, and migrate to the s.c. immunization sites. However, TH cells from 1,25(OH)2D3-treated mice are unable to enter the CNS parenchyma but are instead maintained in the periphery. Upon treatment cessation, mice rapidly develop experimental autoimmune encephalomyelitis, demonstrating that 1,25(OH)2D3 prevents the disease only temporarily likely by halting TH cell migration into the CNS.

Antiviral treatment for Hep C improves renal and cardiovascular outcomes in diabetics
This population-based cohort study aimed to investigate whether antiviral therapy for Hepatitics C Virus (HCV) infection was associated with clinical outcomes in diabetes. From the Taiwan National Health Insurance Research Database, 2,267,270 Taiwanese residents diagnosed with diabetes mellitus were screened for eligibility. After excluding patients with serious comorbidity, they enrolled a total of 1,411 eligible patients who received pegylated interferon plus ribavirin (treated cohort), and matched them 1:1 with 1,411 untreated controls by propensity scores (untreated cohort). Participants were followed up for the occurrence of end-stage renal disease (ESRD), ischemic stroke, and acute coronary syndrome (ACS) after receiving antiviral treatment or the corresponding calendar date. The results showed that from 2003 to 2011, the 8-year cumulative incidences of ESRD in the treated, untreated, and uninfected cohorts were 1.1%, 9.3%, and 3.3% respectively; those of stroke were 3.1%, 5.3%, and 6.1%, respectively; and those for ACS were 4.1%, 6.6%, and 7.4%, respectively. As compared with the untreated cohort, antiviral treatment was associated with multivariate-adjusted hazard ratios of 0.16 for ESRD, 0.53 for ischemic stroke, and 0.64 for ACS, respectively. The authors conclude antiviral therapy for HCV improves clinical outcomes in diabetes. Hepatology, October 2013.
CAMH and Assurex Health launch joint venture to advance personalized medicine
The Centre for Addiction and Mental Health (CAMH), Canada’s leading hospital for mental health, and Assurex Health, a global leader in personalized medicine, have signed an agreement for a joint venture to bring the benefits of this treatment approach to more Canadians. The personalized approach helps to match the right medication at the right dose for each patient, based on their genetic makeup. Using Assurex Health’s GeneSight panel, physicians can easily see which psychiatric medications are likely to be effective for each patient and which ones are not, often avoiding treatment failure and side effects. “This partnership between CAMH and Assurex Health is essential to advance the widespread use of personalized medicine in psychiatry, and improve health care for Canadians who need medications for mental health problems,” said Dr. James Kennedy, head of the Tanenbaum Centre for Pharmacogenetics at CAMH. This approach is a game-changer from the current trial-and-error approach to prescribing, which results in many patients having to try different psychiatric medications, each with potential side-effects, before the best medication for them can be determined. In the U.S., Assurex Health data shows a 70 per cent improvement in depressive symptoms when GeneSight testing is used to predict patient response to antidepressants versus treatment as usual, and a 28 per cent reduction in health care costs.
Health Canada Privacy Blunder Undermines New Medical Cannabis Program
The Canadian Association of Medical Cannabis Dispensaries (CAMCD) is outraged about Health Canada identifying 40,000 medical cannabis patients and producers by sending them correspondence with “Marihuana Medical Access Program” in the return address, contrary to their standard procedure. “This privacy breach violates patient rights and undermines Health Canada’s attempts at reforming their medical cannabis program,” said Adam Greenblatt, CAMCD president. “If Health Canada is trying to instill confidence in a mail-order distribution system for medical cannabis, they are not off to a good start.” The correspondence in question contained informational materials about the reasons behind Health Canada’s regulatory reform, which ironically includes an increased risk of home invasion for patients who grow their own medical cannabis. “Patients are already very concerned that their personal medical information will be turned over to police and realtors when Health Canada revokes their permits next year,” continued Greenblatt. “These patients are accustomed to producing their own supply or accessing a storefront medical cannabis dispensary, yet both options are prohibited under Health Canada’s new regime.” The Deputy Minister of Health issued a bewildered apology, but CAMCD is unimpressed. CAMCD was established to promote a regulated, community-based approach to medical cannabis access, and to support dispensaries in providing the highest quality patient care.

The Permira funds’, the Fonds’ and CDPQ’s resources provide us the ability to accelerate our growth with the financial ability to expand globally. We look forward to working with our three partners and taking the Company to a new level to realize its full potential.”
SIMPONI® I.V. (golimumab) becomes first fully human Anti-TNF infusion therapy
Janssen Inc. announced that Health Canada has approved SIMPONI® I.V. (golimumab) for infusion for the treatment of adults with moderately to severely active rheumatoid arthritis (RA) in combination with methotrexate. SIMPONI® I.V. is the first and only fully human anti-tumour necrosis factor (TNF)-alpha infusible therapy approved in Canada to treat moderately to severely active RA. “The approval of golimumab for infusion offers patients living with moderately to severely active RA a new and effective treatment option with an infusion time of 30 minutes. In addition, it is dosed based on weight, which means it can offer patients a more tailored option,” said Dr. Edward Keystone, Mount Sinai Hospital. Approximately 300,000 Canadians are living with RA, a chronic, systemic inflammatory condition. RA is often characterized by symptoms of joint inflammation, stiffness and pain that, over time, spread to more joints. The approval of SIMPONI® I.V. is supported by findings from the Phase 3 Trial of Golimumab, an Anti-TNF-alpha Monoclonal Antibody, Administered Intravenously, in Subjects with Active Rheumatoid Arthritis Despite Methotrexate Therapy (GO-FURTHER).
Making an Impact on the high-risk behaviour of teens
For over 20 years, London Health Sciences Centre’s (LHSC) trauma program has been making an impact on the knowledge, attitudes and behaviours of teenagers to reduce drinking/drugging and driving through its Impact program. Impact aims to heighten teen awareness of the potential consequences of high-risk behaviour. Over the past year, LHSC’s injury prevention team conducted focus groups with over 200 grade 10 and 11 students at 10 London and surrounding area secondary schools. “We wanted a fresh understanding of all the issues affecting teenagers and driving in order to educate them about the consequences of high-risk behaviour in a way that is relevant and meaningful to them,” says Jane Harrington, injury prevention specialist, LHSC. The focus groups at secondary schools revealed that 55 percent of high school students surveyed drank alcohol in the past year, 22 per cent had used cannabis in the last year, 14 per cent had used opioid pain relievers in the last year and 8.7 per cent had smoked cigarettes. Acting upon student feedback, LHSC’s trauma program partnered with Josh Field Support Network, a non-profit, family based organization, with the mission of raising awareness of the dangers of distracted driving.

IRCM researchers discover a protein’s critical role in the brain for anxiety disorders
A team of Montréal researchers at the IRCM led by Dr. Nabil G. Seidah, in collaboration with Dr.William C. Wetsel’s team at Duke University in the United States, discovered that the protein PC7 plays a critical role in the brain by affecting certain types of cognitive performance such as anxiety, learning and emotional memory. Their results, recently published in the scientific journals Proceedings of the National Academy of Sciences (PNAS) and Nature, could have a significant impact on regulating behaviour related to anxiety disorders and trauma. The scientists found that PC7, the seventh member of the proprotein convertase family responsible for converting inactive proteins into their active states, plays a critical role in specific areas of the brain such as the hippocampus and amygdala, which are important for memory and emotional reactions and are involved in anxiety responses. The results of various behavioural tests in mice lacking PC7 revealed that while spatial memory remained intact, episodic and emotional memories were severely impaired. Episodic memory, the recollection of past events or experiences, can trigger a change in behaviour as a result of an event. “Collectively, these findings indicate that deletion of PC7 in mice could have substantial effects on certain types of cognitive performance,” concludes Dr. Seidah. “We believe that a drug targeting PC7 could increase levels of dopamine and BDNF in the brain, thereby normalizing behaviour. This discovery could be very significant for a number of conditions related to anxiety and trauma, such as bipolar disorder and posttraumatic stress disorder.”
