Worsening spasticity due to catheter breakage during intrathecal baclofen therapy: a case report.

Background: Intrathecal baclofen therapy can substantially improve symptoms in patients with severe spasticity owing to traumatic spinal cord injury, multiple sclerosis, cerebral paresis, or tethered cord syndrome. Problems associated with intrathecal catheters include migration, laceration, occlusion, or disconnection. Several case reports have described the management of catheter fragments.

Cardiac-output response to exercise after allogeneic hematopoietic stem cell transplantation: a case report with a 2-year follow-up.

Cardiac-output response to exercise was evaluated over a 2-year period in hematopoietic stem cell transplant recipients treated with cardiotoxic drugs. During the study period, resting cardiac function was normal; however, the cardiac output response to exercise decreased, and an association with exercise tolerance was observed. Regular assessments of cardiopulmonary function and exercise guidance are vital for patients at high risk of cancer therapy-related cardiac dysfunction, in line with the principles of cardiac oncology rehabilitation.

Plasminogen activator inhibitor-1 promotes immune evasion in tumors by facilitating the expression of programmed cell death-ligand 1.

Background: Increased levels of plasminogen activator inhibitor-1 (PAI-1) in tumors have been found to correlate with poor clinical outcomes in patients with cancer. Although abundant data support the involvement of PAI-1 in cancer progression, whether PAI-1 contributes to tumor immune surveillance remains unclear. The purposes of this study are to determine whether PAI-1 regulates the expression of immune checkpoint molecules to suppresses the immune response to cancer and demonstrate the potential of PAI-1 inhibition for cancer therapy.

Variable Photoluminescence Intensity Ratio with the Excitation Wavelength in Eu-Doped Perovskite-Type Alkaline Earth Zirconates─Possibility of a Unique Visualization of Ultraviolet Light.

Photoluminescence (PL) spectra arising from 4f-4f dipole transitions of Eu doped at both the and sites of perovskite-type alkaline earth zirconates obtained at various excitation wavelengths were evaluated. Changes in the excitation wavelength caused obvious differences in the PL intensity ratio of the induced electric dipole (ED) D → F transition to the magnetic dipole (MD) D → F transition for Eu-doped SrZrO and CaZrO, in which only the B site had a center of symmetry. Two charge transfer (CT) bands associated with the excitation of Eu were observed in the spectra of these oxide samples, which arose from the difference in the electronic structure of the Eu-O coordination at the A and B sites.

Conjoined lumbosacral nerve root: a case report.

Background: In patients with conjoined nerve roots, hemilaminectomy with sufficient exposure of the intervertebral foramen or lateral recess is required to prevent destabilization and ensure correct mobility of the lumbosacral spine. To the best of our knowledge, no case reports have detailed the long-term course of conjoined nerve roots after surgery.

Case Presentation: We report the case of a 51-year-old Japanese man with a conjoined nerve root.

Massive Hemorrhage Associated With Upper Cervical Vertebral Fracture Treated Successfully With Transcatheter Arterial Embolization: A Case Report.

Blunt vertebral artery injuries (BVAI) associated with cervical spine fractures are often problematic due to symptoms of occlusion. Denver grade V cases, in which the vertebral artery is transected, are rare but often fatal, and treatment has rarely been reported. We encountered a case of hemorrhagic shock due to an injury to a branch of the vertebral artery associated with an upper cervical spine fracture.

Decompression for lumbar spinal stenosis at the intrathecal catheter insertion site during intrathecal baclofen therapy: a case report.

Background: Intrathecal baclofen therapy can substantially improve symptoms in most patients with severe spasticity due to traumatic spinal cord injury, multiple sclerosis, or cerebral paresis. To the best of our knowledge, decompression surgeries at the intrathecal catheter insertion site in patients with a preexisting intrathecal pump for drug delivery have not been reported.

Case Presentation: We report the case of a 61-year-old Japanese man with lumbar spinal stenosis who underwent intrathecal baclofen therapy.

Case report: Physical findings, physical therapy practice, and characteristics of disability of activities of daily living caused by obturator nerve palsy after neurotmesis.

The obturator nerve originates from the lumbar plexus and innervates sensation in the thigh and movement of the adductor muscle group of the hip. Reports on physical therapy for patients with obturator nerve injuries have been limited due to insufficient injuries, and there have been no reports on rehabilitation after neurotmesis. Furthermore, there are no reports on the status of activities of daily living (ADL) and details of physical therapy in patients with paralysis of the adductor muscle group.

Delivering mRNAs to mouse tissues using the SEND system.

mRNAs produced in a cell are almost always translated within the same cell. Some mRNAs are transported to other cells of the organism through processes involving membrane nanotubes or extracellular vesicles. A recent report describes a surprising new phenomenon of encapsulating mRNAs inside virus-like particles (VLPs) to deliver them to other cells in a process that was named SEND (Selective Endogenous eNcapsidation for cellular Delivery).

Ultraearly Hematoma Evacuation (<12 Hours) Associated with Better Functional Outcome in Patients with Symptomatic Spontaneous Spinal Epidural Hematoma.

Background: Early decompressive surgery within 24 hours improves the functional outcome of patients with traumatic spinal cord injury; however, little is known about the effect of early surgery for spontaneous spinal epidural hematoma (SSEH). In this study, we aimed to investigate the effectiveness of ultraearly hematoma evacuation (<12 hours) for SSEH.

Methods: Patients with SSEH treated with surgical hematoma evacuation at our institution between January 2000 and July 2021 were retrospectively analyzed.

Mitochondrial Electron Transport Chain Complex II Dysfunction Causes Premature Aging of Hematopoietic Stem Cells.

Mitochondria are indispensable in maintaining hematopoietic stem cells (HSCs), and mitochondrial complex II (MCII) has been recognized as a key component of HSCs. However, the physiological role of MCII on long-term hematopoiesis and hematopoietic reconstitution capacity remains unknown. Hence, this study evaluated the impact of MCII dysfunctions on long-term HSC maintenance and hematopoietic homeostasis among conditional transgenic mice with a missense mutation in the succinate dehydrogenase complex subunit C gene (SdhcV69E).

Longitudinal changes in nailfold videocapillaroscopy findings differ by myositis-specific autoantibody in idiopathic inflammatory myopathy.

Background: This study aimed to investigate the effect of anterior cruciate ligament (ACL) reconstruction with an ultrasound-guided femoral nerve block (FNB) on knee extensor strength weakness 3 and 6 months, and graft rupture in the 1 year following ACL reconstruction.

Methods: One hundred and seven patients who underwent ACL reconstruction were included in this retrospective study. The patients were divided into two groups stratified by the method of postoperative pain management.

Pterostilbene downregulates BCR/ABL and induces apoptosis of T315I-mutated BCR/ABL-positive leukemic cells.

In this study, we examined the antileukemic effects of pterostilbene, a natural methylated polyphenol analog of resveratrol that is predominantly found in berries and nuts, using various human and murine leukemic cells, as well as bone marrow samples obtained from patients with leukemia. Pterostilbene administration significantly induced apoptosis of leukemic cells, but not of non-malignant hematopoietic stem/progenitor cells. Interestingly, pterostilbene was highly effective in inducing apoptosis of leukemic cells harboring the BCR/ABL fusion gene, including ABL tyrosine kinase inhibitor (TKI)-resistant cells with the T315I mutation.
