Dimensionality of the Pittsburgh Sleep Quality Index in the collegiate young adults.

Purpose: To explore and validate the factor structure of the Pittsburgh Sleep Quality Index (PSQI) in the collegiate young adults.

Methods: Six hundred university students were initially contacted and invited to participate in a survey of their sleep experience and history. Of this preliminary sample 418 of the students (age = 20.

Melatonin and Human Cardiovascular Disease.

The possible therapeutic role of melatonin in the pathophysiology of coronary artery disorder (CAD) is increasingly being recognized. In humans, exogenous melatonin has been shown to decrease nocturnal hypertension, improve systolic and diastolic blood pressure, reduce the pulsatility index in the internal carotid artery, decrease platelet aggregation, and reduce serum catecholamine levels. Low circulating levels of melatonin are reported in individuals with CAD, arterial hypertension, and congestive heart failure.

Association of Sleep Duration with Stroke in Diabetic Patients: Analysis of the National Health Interview Survey.

Background: Habitual sleep duration is increasingly being recognized as an important risk factor for stroke. We sought to describe the association between sleep duration and stroke in a cohort of individuals with diabetes.

Methods: Data from the National Health Interview Survey for the years 2004-2013 were used.

Polyaxial Screws in Locked Plating of Tibial Pilon Fractures.

This study examined the axial and torsional stiffness of polyaxial locked plating techniques compared with fixed-angle locked plating techniques in a distal tibia pilon fracture model. The effect of using a polyaxial screw to cross the fracture site was examined to determine its ability to control relative fracture site motion. A laboratory experiment was performed to investigate the biomechanical stiffness of distal tibia fracture models repaired with 3.

A single volar incision fasciotomy will decompress all three forearm compartments: a cadaver study.

Introduction: Although there are three distinct compartments of the forearm, the typical approach for decompression of forearm compartment syndrome is a single incision fasciotomy of the volar compartment. This study had two purposes. The first purpose of this study was to investigate the compartment pressure changes within the forearm compartments following the creation of an acute compartment pressure using fresh-frozen cadaver forearm specimens.

Vascular risk reduction during anterior surgical approach sacroiliac joint plating.

Introduction: Open reduction and internal fixation of sacroiliac (SI) joint is often performed through an anterior approach. However, there were no studies to our knowledge which described the "at risk area" for injury to the nutrient artery as it relates to open reduction and internal fixation of the SI joint. The purpose of this study was to determine the "at risk area" for the nutrient artery during anterior surgical approaches to the SI joint and to define the safe location of the plate for SI joint fixation.

Pelvic compartment syndrome: a systematic review.

Bilateral ureteral obstruction due to traumatic pelvic haematoma and increased pressure in the retroperitoneal space constitute an acute pelvic compartment syndrome. We systematically reviewed the available evidence concerning pelvic compartment syndrome using an online search of the MEDLINE databases OVID and PubMed. There were nine cases of pelvic compartment syndrome.

Venous thromboembolism in shoulder surgery: a systematic review.

Although it is generally believed that venous thromboembolism (VTE) after shoulder surgery is very rare, there are increasing reports of deep venous thrombosis (DVT) and pulmonary embolism (PE) associated with shoulder surgery. To our knowledge only few studies have reviewed the available evidence on the subject. The purpose of this study was to review the available evidence in the published literature regarding incidence, risk factors, diagnosis and management of DVT/PE following shoulder surgery (Level IV evidence).

Anterolateral and medial locking plate stiffness in distal tibial fracture model.

Background: The purpose of this study was to compare the axial and torsional stiffness between anterolateral and medial distal tibial locking plates in a pilon fracture model.

Materials And Methods: The biomechanical stiffness of anterolateral or medial plated pilon fracture models was evaluated. Six Sawbones Composite Tibiae with a simulated pilon fracture representing varus or valgus comminution (OTA 43-A2.

Technique for precise placement of poller screws with intramedullary nailing of metaphyseal fractures of the femur and the tibia.

Intramedullary nailing is the accepted treatment of femoral and tibial shaft fractures. Improvements in surgical techniques and implant designs have extended indications for nailing to metaphyseal fractures of the proximal tibia, distal tibia and the distal femur. Malalignment can still occur with intramedullary nailing of these fractures.

Foot compartment syndrome: a systematic review of the literature.

We systematically reviewed published evidence regarding foot compartment syndrome with regards to causes, methods of diagnosis, number of incisions used for fasciotomy, wound closure techniques, complications, and functional outcomes. Publications were collected using PubMed and OVID databases, and were reviewed as above. All were retrospective case series (evidence-based medicine level IV).

Compartment syndrome of the thigh: a systematic review.

Introduction: Thigh compartment syndrome is a surgical emergency with risk of high morbidity and mortality rates. The purpose of this study was to review the available evidence regarding the causes of thigh compartment syndrome, techniques of fasciotomy (specifically, one versus two incisions), methods of wound closure, and complications.

Methods: This institutional review board-exempt study was performed at a level-one trauma centre.
