CT-Defined Pectoralis Muscle Density Predicts 30-Day Mortality in Hospitalized Patients with COVID-19: A Nationwide Multicenter Study.

Rationale And Objectives: The prognostic role of computed tomography (CT)-defined skeletal muscle features in COVID-19 is still under investigation. The aim of the present study was to evaluate the prognostic role of CT-defined skeletal muscle area and density in patients with COVID-19 in a multicenter setting.

Materials And Methods: This retrospective study is a part of the German multicenter project RACOON (Radiological Cooperative Network of the COVID-19 pandemic).

Minimally Invasive Spine Surgery for Lumbar Decompression or Disc Herniation.

Many people experience low back pain caused by degenerative disease of the lumbar spine; this includes spinal stenosis, spondylolisthesis, disc degeneration, and disc herniation. Conservative management of degenerative disease, which includes physical therapy, lifestyle modifications, and medications, is the initial approach. If this approach fails, a surgical procedure may be the next step.

AI supported detection of cerebral multiple sclerosis lesions decreases radiologic reporting times.

Purpose: Multiple Sclerosis (MS) is a common autoimmune disease of the central nervous system. MRI plays a crucial role in diagnosing as well as in disease and treatment monitoring. Therefore, evaluation of cerebral MRI of MS patients is part of daily clinical routine.

Diversity of unique, nonmycorrhizal endophytic fungi in cultivated orchids: A pilot study.

Orchids comprise one of the largest, most diverse, and most broadly distributed families of flowering plants and contribute significantly to habitat biodiversity. One key aspect of orchid growth and development is the formation of mycorrhizal symbioses with compatible endophytic fungi, which are maintained throughout the life of the plant. Substantial efforts to identify the fungi that form mycorrhizal symbioses across a range of orchid species have often also uncovered numerous nonmycorrhizal, endophytic fungi.

Encephaloduroarteriosynangiosis Procedure: A Treatment Option for Patients With Moyamoya Disease.

Moyamoya disease is a progressive cerebrovascular disorder for which there is no cure. It is characterized by narrowing of and occlusions in the blood vessels that supply the brain, which causes a fine vascular network to develop to serve as collateral pathways. Moyamoya disease can lead to a reduction of blood flow to the brain and increase the risk of stroke.
