Comparison of Clinical Outcomes of Two-Level PELD and Foraminoplasty PELD for Highly Migrated Disc Herniations: A Comparative Study.
The aim of this study is to compare the clinical outcomes of two-level percutaneous endoscopic lumbar discectomy (PELD) and foraminoplasty PELD in treating highly migrated lumbar disc herniations. ⋯ Both two-level PELD and foraminoplasty PELD are safe and effective surgical procedures for the patients with highly migrated lumbar disc herniations. Moreover, the two-level PELD technique has merits in reducing the incidence of postoperative nucleus pulposus residue.

Lung cancer is a leading cause of death worldwide. Although computed tomography (CT) examinations are frequently used for lung cancer diagnosis, it can be difficult to distinguish between benign and malignant pulmonary nodules on the basis of CT images alone. Therefore, a bronchoscopic biopsy may be conducted if malignancy is suspected following CT examinations. ⋯ The DCNN is trained using nodule images generated by the GAN and then fine-tuned using the actual nodule images to allow the DCNN to distinguish between benign and malignant nodules. This pretraining and fine-tuning process makes it possible to distinguish 66.7% of benign nodules and 93.9% of malignant nodules. These results indicate that the proposed method improves the classification accuracy by approximately 20% in comparison with training using only the original images.

We present entry and exit screening outcomes on all persons passing through Freetown International Airport (FNA) in Sierra Leone during the period 1st September 2014 to 4th February 2016. A total of 166,242 persons underwent screening for Ebola Virus Disease (EVD) at FNA. ⋯ No cases were identified through entry screening route. The public health value of airport screening for EVD is discussed.

The collagen density is not detected in the patellar tendon (PT), posterior cruciate ligament (PCL), and anterior cruciate ligament (ACL) in clinic. We assess the technical feasibility of three-dimension multiecho fat saturated ultrashort echo time cones (3D FS-UTE-Cones) acquisitions for single- and bicomponent T2⁎ analysis of bound and free water pools in PT, PCL, and ACL in clinic. The knees of five healthy volunteers and six knee joint samples from cadavers were scanned via 3D multiecho FS-UTE-Cones acquisitions on a clinical scanner. ⋯ For knee joint samples, there was no statistical difference among all data in PT, PCL, and ACL. For volunteers, all parameters of bicomponent fitting were statistically different across PT, PCL, and ACL, except for T2⁎S, T2⁎L, and T2⁎M resulting in flawed measurements due to the magic angle effect. 3D multiecho FS-UTE-Cones acquisition allows high resolution T2⁎ mapping in PT, PCL, and ACL of keen joint samples and PT and PCL of volunteers. The T2⁎ values and their fractions can be characterized by bicomponent T2⁎ analysis that is superior to single-component T2⁎ analysis, except for ACL of volunteers.

Staff shortages among nurses have been severely felt in most countries around the world for many years. In Poland, this problem is particularly visible due to the lowest nursing employment rate per 1000 inhabitants among 28 EU states and the high rate of leaving the profession. The average age of Polish nurses has been constantly growing for several years-in 2016 it was 50.79, while in 2008 it was 44.19. These data confirm that young nurses are the first to leave the profession. Diagnosis of the working conditions and psychosocial burden level among nurses should be subject to detailed analysis, so that leaving the profession will not additionally deepen the difficult staffing situation in health care. ⋯ (1) The study results indicate the need to diagnose problems related to work conditions in the context of occupational stress within individual hospital wards. To limit employee turnover, nursing staff managers should approach the issue of improving working conditions individually for each ward, due to differences in the nature of the work and level of stressogenicity. (2) In each hospital ward, employees at different stages of their career are sensitive to the psychosocial burden resulting from different work characteristics. These areas should be thoroughly diagnosed and the burden minimized to prevent departures from the profession-at early stages of the professional career as well as among experienced personnel. (3) Nurses working in managerial positions should receive the necessary substantive support, due to the higher stress burden associated with greater responsibility.
