Spinal metastases are the most commonly encountered tumour of the spine, occurring in up to 40% of patients with cancer. Each year, approximately 5% of cancer patients will develop spinal metastases. This number is expected to increase as the life expectancy of cancer patients increases. Patients with spinal metastases experience severe and frequently debilitating pain, which often decreases their remaining quality of life. With a median survival of less than 1 year, the goals of treatment in spinal metastases are reducing pain, improving or maintaining level of function and providing mechanical stability...

This literature search concerning the potential role of spinal orthoses for rehabilitation and treatment of atraumatic vertebral fractures between Th4 and L5 with osteoporosis and without any evidence for a secondary cause, provided no evidence for the benefits of traditional rigid thoracolumbar corsets, which only had a poor compliance. In addition, there are indications that these rigid corsets may even worsen the disease condition especially in the long-term. Wearing these corsets can result in further loss of muscle mass and strength followed by loss of bone and bone mass...

BACKGROUND: Initial declines in bone mineral density (BMD) following antiretroviral therapy (ART) initiation in HIV are well described, but data on long-term changes and risk factors for decline, particularly among women, are limited. METHODS: HIV-infected men and women in the Modena Metabolic Clinic underwent dual-energy X-ray absorptiometry (DXA) scans every 6-12 months for up to 10 years (median 4.6 years). Mixed effect regression model in combined and sex-stratified models determined annual rates of decline and clinical factors associated with BMD...

Schizophrenia (SCZ) is a neuropsychiatric disorder that is linked to social behavioral deficits and other negative symptoms associated with hippocampal synaptic dysfunction. Synaptic mechanism of schizophrenia is characterized by loss of hippocampal N-Methyl-d-Aspartate Receptor (NMDAR) activity (NMDAR hypofunction) and dendritic spines. Previous studies show that genetic deletion of hippocampal synaptic regulatory calcium-calmodulin dependent kinase II alpha (CaMKIIα) cause synaptic and behavioral defects associated with schizophrenia in mice...

The integration of 1.5 T MRI functionality with a radiotherapy linear accelerator (linac) has been pursued since 1999 by the UMC Utrecht in close collaboration with Elekta and Philips. The idea behind this integrated device is to offer unrivalled, online and real-time, soft-tissue visualization of the tumour and the surroundings for more precise radiation delivery. The proof of concept of this device was given in 2009 by demonstrating simultaneous irradiation and MR imaging on phantoms, since then the device has been further developed and commercialized by Elekta...

This matched case-control study compared the computed tomography (CT)-based regional bone density of patients with fragility fractures of the sacrum to a control without fracture. Patients with a sacral fracture demonstrated a significantly lower regional bone density of the sacrum, the sacral bone density not being correlated with the BMD by DXA of the spine. INTRODUCTION: The aim of this study is to compare the computed tomography-based regional bone density measured by Hounsfield units (HUs) in patients with and without fragility fractures of the sacrum...

Functional synapse formation is critical for the wiring of neural circuits in the developing brain. The cell adhesion molecule N-cadherin plays important roles in target recognition and synaptogenesis. However, the molecular mechanisms that regulate the localization of N-cadherin and the subsequent effects remain poorly understood. Here, we show that protein kinase D1 (PKD1) directly binds to N-cadherin at amino acid residues 836-871 and phosphorylates it at Ser 869, 871, 872, thereby increasing the surface localization of N-cadherin and promoting functional synapse formation in primary cultured hippocampal neurons obtained from embryonic day 18 rat embryos of either sex...

REVIEW
George Kovacs, Nicholas Sowers
Airway management in the trauma patient presents numerous unique challenges beyond placement of an endotracheal tube and outcomes are dependent on the provider's ability to anticipate difficulty. Airway management strategies for the care of the polytrauma patient are reviewed, with specific considerations for those presenting with traumatic brain injury, suspected c-spine injury, the contaminated airway, the agitated trauma patient, maxillofacial trauma, and the traumatized airway. An approach to airway management that considers the potential anatomic and physiologic challenges in caring for these complicated trauma patients is presented...

Post-operative epidural fibrosis is a biological response after laminectomy that may lead to clinical symptoms, such as radicular pain. An ideal material for prevention of epidural fibrosis should be able to inhibit fibroblast adhesions and reduce formation of scar tissue. An injectable hydrogel would be the material of choice for this purpose, since it could fill an irregular surgical defect completely, gelate in situ and be delivered in a minimally-invasive manner. The objective of this study was to evaluate, in vitro and in vivo, the cytocompatibility and anti-adhesive effect of an oxidised hyaluronic acid/adipic acid dihydrazide (oxi-HA/ADH) hydrogel...

The spine has been the subject of extensive clinical research since it is the source of many painful complaints. However, there is little scientific evidence concerning the therapeutic proposals. During the course of life, the intervertebral disc degenerates, which over time diminishes its damping capacity and facilitates the expulsion of the nucleus pulposus through the annulus fibrosus. The degeneration of the intervertebral disc (DDI) is the origin of some back pain and various specific treatments have been developed...

INTRODUCTION: Vertebral hemangiomas (VH) represent the most common primary bone tumor of the spine and are rarely symptomatic. Currently, there is no consensus for treatment and many therapeutic options are available, alone or in combination including cementoplasty, sclerotherapy, surgery, embolization and/or radiotherapy. OBJECTIVE: To evaluate the clinical and radiological outcome of a multimodal management for symptomatic VH. METHODS: A consecutive prospective and retrospective multicenter study was conducted to review cases of symptomatic VHs between 2005 and 2015...
