Experimental study of laser scattering protection system for low-speed aircraft.

This study introduces a laser scattering system to protect a low-speed aircraft. Scattering was selected to reduce the laser's intensity targeting the sensor of an aircraft and simultaneously maintaining the functionality of aircraft optics. Mie scattering, known for effectively decreasing short-wave infrared light, was employed by utilizing water aerosols having a diameter of 1 to 5 μm.

Pulmonary venous thrombosis in a healthy pregnancy.

We describe an unusual case of bilateral pulmonary venous thrombosis in a pregnant woman in her mid 30s, who presented at 34 weeks of gestation with symptoms of sudden onset chest pain, shortness of breath and near syncope attacks. The patient was treated with enoxaparin and made an excellent clinical and hemodynamic recovery.

Evaluating Single-Surgeon Bias Toward Recommending Corrective Procedures for Cervical Spondylotic Myelopathy Based on Demographic Factors and Comorbidities in a 484-Patient Cohort.

Study Design: Retrospective case series.

Objectives: An increasing focus has been placed on removing implicit (unconscious) bias from the surgical selection process. In spine surgery, there is the potential for implicit bias to affect the decision to either operate on a patient or not, given lack of definitive surgical indications for many elective procedures.

Next-generation sequencing for the diagnosis of MYH9-RD: Predicting pathogenic variants.

The heterogeneous manifestations of MYH9-related disorder (MYH9-RD), characterized by macrothrombocytopenia, Döhle-like inclusion bodies in leukocytes, bleeding of variable severity with, in some cases, ear, eye, kidney, and liver involvement, make the diagnosis for these patients still challenging in clinical practice. We collected phenotypic data and analyzed the genetic variants in more than 3,000 patients with a bleeding or platelet disorder. Patients were enrolled in the BRIDGE-BPD and ThromboGenomics Projects and their samples processed by high throughput sequencing (HTS).

Factors Associated With Return-to-Work Following Cervical Spine Surgery in Non-Worker's Compensation Setting.

Study Design: This study retrospectively analyzes prospectively collected data.

Objective: Here in this study we aim to determine the factors which impact a patient's ability to return to work (RTW) in the setting of cervical spine surgery in patients without worker's compensation status.

Summary Of Background Data: Surgical management of degenerative cervical disease has proven cost-effectiveness and shown significant improvement in quality of life.

Effect of Depression on Patient-Reported Outcomes Following Cervical Epidural Steroid Injection for Degenerative Spine Disease.

Objective: To assess the effect depression has on outcomes after cervical epidural steroid injections (CESIs).

Design: Retrospective review of a prospectively collected database.

Setting: Single institution tertiary care center.

Timing of Operative Intervention in Traumatic Spine Injuries Without Neurological Deficit.

Background: Numerous studies have demonstrated the benefits of early decompression and stabilization in unstable spine injuries with incomplete neurological deficits. However, a clear consensus on timing to operative intervention still does not exist in those with a normal neurological exam and unstable spine.

Objective: To determine the optimal timing of operative intervention in traumatic spine injuries without neurological deficit.

Patient-Reported Outcomes and Costs Associated With Revision Surgery for Degenerative Cervical Spine Diseases.

Study Design: A retrospective review of a prospective database.

Objective: The aim of this study was to determine cost and outcomes of revision cervical spine surgery.

Summary Of Background Data: Revision rates for cervical spine surgery are steadily increasing.

Surgical Management of Cervical Spondylotic Myelopathy.

Cervical spondylotic myelopathy (CSM) is a common cause of neurologic impairment in adults worldwide. Numerous studies have investigated the pathophysiology of CSM, which has provided surgeons with insight on the important factors that lead to the symptoms and deficits observed in patients who have CSM. However, further analysis of many unknown aspects of CSM is required to fully understand the disease and potential alternative treatment modalities.

A retrospective review comparing two-year patient-reported outcomes, costs, and healthcare resource utilization for TLIF vs. PLF for single-level degenerative spondylolisthesis.

Purpose: The purpose of this study was to compare patient-reported outcomes (PROs), morbidity, and costs of TLIF vs PLF to determine whether one treatment was superior in the setting of single-level degenerative spondylolisthesis.

Methods: Patients undergoing TLIF or PLF for single-level spondylolisthesis were included for retrospective analysis. EQ-5D, ODI, SF-12 MCS/PCS, NRS-BP/LP scores were collected at baseline and 24 months after surgery.

Need for Two-Year Patient-Reported Outcomes Score for Lumbar Spine Surgery Is Procedure-Specific: Analysis From a Prospective Longitudinal Spine Registry.

Study Design: Retrospective analysis of prospectively collected data.

Objective: The aim of this study was to determine whether 1-year patient-reported outcomes (PROs) can accurately assess effective care for patients undergoing surgery for degenerative lumbar spine disease.

Summary Of Background Data: Prospective longitudinal PROs registries provide a means to accurately assess outcomes and determine the relative effectiveness of various spine treatments.

Patient-reported outcomes after lumbar epidural steroid injection for degenerative spine disease in depressed versus non-depressed patients.

Background Context: Medical interventional modalities such as lumbar epidural steroid injections (LESIs) are often used in the setting of lumbar spine disorders where other conservative measures have failed. Concomitant depression can lead to worse outcomes in lumbar spine pathology. A number of studies have demonstrated an association between preoperative depression and poor outcomes following surgery, but the effect of depression on outcomes following medical interventional modalities is poorly understood.

Topical Cyclosporine A 1% for the Treatment of Chronic Follicular Conjunctivitis.

Objective: To evaluate the use of topical cyclosporine A (CSA) 1% in the treatment of chronic follicular conjunctivitis (CFC).

Methods: Retrospective chart review from 2001 to 2012 identified 12 patients (22 eyes) with CFC (mean ± standard deviation [SD] age, 50.2 ± 15.

Rigid Intramedullary Nailing of Femoral Shaft Fractures in Skeletally Immature Patients Using a Lateral Trochanteric Entry Portal.

Introduction: We describe rigid intramedullary nailing using a trochanteric entry for internal fixation of femoral shaft fractures in older children and adolescents.

Step 1 Preparation Prior To Incision: Appropriate preparation prior to the operation is key to minimizing intraoperative and postoperative complications.

Step 2 Perform Incision And Exposure: A well-positioned incision will facilitate and reduce difficulty with ideal guidewire placement.

Twenty-Year Experience with Rigid Intramedullary Nailing of Femoral Shaft Fractures in Skeletally Immature Patients.

Background: Debate exists over the safety of rigid intramedullary nailing of femoral shaft fractures in skeletally immature patients. The goal of this study was to describe functional outcomes and complication rates of rigid intramedullary nailing in pediatric patients.

Methods: A retrospective review was performed of femoral shaft fractures in skeletally immature patients treated with trochanteric rigid intramedullary nailing from 1987 to 2009.

Cellular mechanics of germ band retraction in Drosophila.

Germ band retraction involves a dramatic rearrangement of the tissues on the surface of the Drosophila embryo. As germ band retraction commences, one tissue, the germ band, wraps around another, the amnioserosa. Through retraction the two tissues move cohesively as the highly elongated cells of the amnioserosa contract and the germ band moves so it is only on one side of the embryo.
