BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

Shortening of the first ray is a potential complication associated with first metatarsal procedures. Correction of this deformity conventionally has required the use of a tricortical bone graft to lengthen the bone. Graft complications, including donor site morbidity, poor graft stability, and graft resorption, have revealed a need for an alternative procedure. The present report shows that titanium cage scaffolding has lower extremity applications beyond its previous uses in the ankle and spine. Two patients underwent surgical correction for failed first ray procedures using a titanium cage apparatus with a calcaneal autograft and other biologic agents...

The sympathetic nervous system controls and regulates the activities of the heart and other organs. Sympathetic nervous system dysfunction leads to disease. Therefore, intraoperative real-time imaging of thoracic sympathetic nerves (ITSN) would be of great clinical significance for diagnosis and therapy. The aim of this experimental study was to evaluate the feasibility and validity of intraoperative ITSN using indocyanine green (ICG). METHODS: ITSN using ICG was performed on 10 rabbits to determine its feasibility...

Extreme environments, such as subterranean habitats, are suspected to be responsible for morphologically inseparable cryptic or sibling species and can bias biodiversity assessment. A DNA barcode is a short, standardized DNA sequence used for taxonomic purposes and has the potential to lessen the challenges presented by a biotic inventory. Here, we investigate the diversity of the genus Leptonetela Kratochvíl, 1978 that is endemic to karst systems in Eurasia using DNA barcoding. We analyzed 624 specimens using one mitochondrial gene fragment (COI)...

Memories are stored in synapses which consist of axon terminals and dendritic spines. Dendritic spines are postsynaptic structures of synapses and essential for synaptic plasticity and cognition. Therefore, extensive investigations about functions and structures of spines have been performed. Sex steroids and stress steroids have been shown to modulate hippocampal synapses. Although rapid modulatory action of sex steroids on synapses has been studied in hippocampal neurons over several decades, its essential molecular mechanisms have not been fully understood...

Vertebral fusion is performed in order to stabilize the spine in the presence of degenerative, traumatic or oncological pathologies that alter its stability. The autologous bone, harvested from the patient’s iliac crest or from the lamina during surgery, is still considered the “gold standard” for spine fusion due to its osteogenic, osteoinductive and osteoconductive properties. However, several biological and synthetic bone substitutes have been introduced as alternatives for regenerating bone tissue...

The nucleus pulposus (NP) substitution by polymeric gel is one of the promising techniques for the repair of the degenerative intervertebral disc (IVD). Silicone gel is one of the potential candidates for a NP replacement material. Electrospun fiber anchorage to silicone disc, referred as ENAS disc, may not only improve the biomechanical performances of the gel but it can also improve restoration capability of the gel, which is unknown. This study successfully produced a novel process to anchor any size and shape of NP gel with electrospun fiber mesh...

BACKGROUND: Health care spending in the US remains excessively high. Aside from complicated, large-scale efforts at health care cost reduction, there are still relatively simple ways in which individual hospitals can cut unnecessary costs from everyday operations. Inspired by recent publications, our group sought to decrease the costs associated with surgical instrument processing at a large, multihospital academic center. METHODS: This was a single-site observational study conducted at a large academic medical center...

: Consensus statements regarding the evidence-base for lumbar total disc replacement, as it pertains to payer decision-making, were developed through a modified-Delphi technique involving 17 spine surgeons and a former payer medical director. The Delphi process involved one round of anonymous survey and one round with a face-to-face meeting. The survey was a 51-item, electronically administered questionnaire to determine level of agreement with proposed statements on the evidence for lumbar total disc replacement and to provide additional diagnosis and management practice information for further deliberations...

BACKGROUND: In the operative treatment of osteoporotic vertebral body fractures, a dorsal stabilization in combination with a corpectomy of the fractured vertebral body might be necessary with respect to the fracture morphology, whereby the osteoporotic bone quality may possibly increase the risk of implant failure. In order to achieve better stability, it is recommended to use cement-augmented screws for dorsal instrumentation. Beside careful endplate preparation cement augmentation of the adjacent endplates has also been reported to lead to less reduction loss...
