The link between type 1 diabetes mellitus (DM1) and osteoporosis, identified decades ago, has gained attention in recent years. While a number of cellular mechanisms have been postulated to mediate this association, it is now established that defects in osteoblast differentiation and activity are the main culprits underlying bone fragility in DM1. Other contributing factors include an accumulation of advanced glycation end products (AGEs) and the development of diabetes complications (such as neuropathy and hypoglycemia), which cause further decline in bone mineral density (BMD), worsening geometric properties within bone, and increased fall risk. As a result, patients with DM1 have a 6.9-fold increased incidence of hip fracture compared to controls. Despite this increased fracture risk, bone fragility remains an underappreciated complication of DM1 and is not addressed in most diabetes guidelines. There is also a lack of data regarding the efficacy of therapeutic strategies to treat osteoporosis in this patient population. Together, our current understanding of bone fragility in DM1 calls for an update of diabetes guidelines, better screening tools, and further research into the use of therapeutic strategies in this patient population.

Study design: Prospective Pilot Study. Objectives: To determine the safety and feasibility of autologous olfactory mucosal transplantation into the spinal cord in chronic spinal cord injured using the technique developed by Carlos Lima et al. Setting: Spinal Injury Center, New Delhi. Methods: Five chronic, motor complete, traumatic spinal cord injury (SCI) patients with neurological level C5-T12 underwent the procedure. Participants were assessed at baseline and at 6 monthly intervals. Safety and tolerability were evaluated through monitoring for any adverse events and tests including magnetic resonance imaging (MRI) evaluation. Efficacy assessment was done through neurological, functional and psychological evaluation, electrophysiological studies and urodynamics. Results: Surgery was tolerated well by all American Spinal Injury Association (ASIA) Impairment Scale (AIS) A participants. The only AIS B participant lost sensory scores significantly after surgery but is gradually regaining it. MRI evaluation revealed a syrinx in one participant and increase in length of myelomalacia in four participants. There were no other adverse findings on MRI evaluation. There was no significant improvement in any of the neurological, electrophysiological or urodynamic efficacy variables. Statistically significant improvement was seen in functional scores as evaluated by Spinal Cord Independence Measure, Beck Depression Inventory scores and life impact scores on International Spinal Cord Injury Scale. Conclusions: The procedure is relatively safe and feasible in AIS A participants with thoracic level injuries at 18 month follow-up. No efficacy could be demonstrated which could be attributed to the procedure.

This is the first Canadian position statement on the topic of Ramadan fasting and diabetes. It was developed by an expert faculty and endorsed by Diabetes Canada, and provides guidance about pharmacotherapy and glucose monitoring for health-care providers so that they can assist Canadian Muslims living with diabetes to observe fasting during Ramadan safely.
