Update on the impact of type 2 diabetes mellitus on bone metabolism and material properties

Abstract: The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide, especially as a result of our aging society, high caloric intake and sedentary lifestyle. Besides the well-known complications of T2DM on the cardiovascular system, the eyes, kidneys and nerves, bone strength is also impaired in diabetic patients. Patients with T2DM have a 40-70% increased risk for fractures, despite having a normal to increased bone mineral density, suggesting that other factors besides bone quantity must account for increased bone fragility. This review summarizes the current knowledge on the complex effects of T2DM on bone including effects on bone cells, bone material properties and other endocrine systems that subsequently affect bone, discusses the effects of T2DM medications on bone and concludes with a model identifying factors that may contribute to poor bone quality and increased bone fragility in T2DM.

Minimally invasive versus open surgery for acute Achilles tendon rupture: a systematic review

Abstract: Introduction: This review provides a comprehensive description of clinical, functional outcomes, and complications after open and minimally invasive surgery for Achilles tendon ruptures. Sources of data: We systematically searched Medline (PubMED), EMBASE, CINHAL, Cochrane, Sports Discus and Google scholar databases using the combined keywords ‘open repair’, ‘percutaneous surgery’, ‘minimally invasive surgery ’‘ Achilles tendon rupture’, ‘complications’, ‘infections’, ‘wound disorders’ to identify articles published in English, Spanish, French and Italian. Areas of agreement: Twelve studies fulfilled our inclusion criteria. Six studies were retrospective, five were randomized controlled trials and one was a prospective investigation. Of a total of 781 patients, 375 underwent open repair and 406 percutaneous surgery. Different procedures were performed for open and minimally invasive repair. Areas of controversy: The range of motion was significantly greater after percutaneous repair than open surgery. The number of complications that occurred after open surgery was higher than after minimally invasive surgery.

Stimulation of autophagy by rapamycin protects neurons from remote degeneration after acute focal brain damage

Abstract: Autophagy is the evolutionarily conserved degradation and recycling of cellular constituents. In mammals, autophagy is implicated in the pathogenesis of many neurodegenerative diseases. However, its involvement in acute brain damage is unknown. This study addresses the function of autophagy in neurodegeneration that has been induced by acute focal cerebellar lesions. We provide morphological, ultrastructural, and biochemical evidence that lesions in a cerebellar hemisphere activate autophagy in axotomized precerebellar neurons. Through time course analyses of the apoptotic cascade, we determined mitochondrial dysfunction to be the early trigger of degeneration. Further, the stimulation of autophagy by rapamycin and the employment of mice with impaired autophagic responses allowed us to demonstrate that autophagy protects from damage promoting functional recovery. These findings have therapeutic significance, demonstrating the potential of pro-autophagy treatments for acute brain pathologies, such as stroke and brain trauma.
