Prohibitin 1 is essential to preserve mitochondria and myelin integrity in Schwann cells.

Nat Commun 2021 06 2;12(1):3285. Epub 2021 Jun 2.

Hunter James Kelly Research Institute, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, Buffalo, NY, USA.

In peripheral nerves, Schwann cells form myelin and provide trophic support to axons. We previously showed that the mitochondrial protein prohibitin 2 can localize to the axon-Schwann-cell interface and is required for developmental myelination. Whether the homologous protein prohibitin 1 has a similar role, and whether prohibitins also play important roles in Schwann cell mitochondria is unknown. Read More

AAV9-mediated Schwann cell-targeted gene therapy rescues a model of demyelinating neuropathy.

Gene Ther 2021 Mar 10. Epub 2021 Mar 10.

Neuroscience Department, The Cyprus Institute of Neurology and Genetics and Cyprus School of Molecular Medicine, Nicosia, Cyprus.

Mutations in the GJB1 gene, encoding the gap junction (GJ) protein connexin32 (Cx32), cause X-linked Charcot-Marie-Tooth disease (CMT1X), an inherited demyelinating neuropathy. We developed a gene therapy approach for CMT1X using an AAV9 vector to deliver the GJB1/Cx32 gene under the myelin protein zero (Mpz) promoter for targeted expression in Schwann cells. Lumbar intrathecal injection of the AAV9-Mpz. Read More

Association of circulating B-type natriuretic peptide with osteoporosis in a Chinese type 2 diabetic population.

BMC Musculoskelet Disord 2021 Mar 10;22(1):261. Epub 2021 Mar 10.

Department of Endocrinology, The Affiliated Hospital of Southwest Medical University, Luzhou, 646000, Sichuan, China.

Background: Altered circulating levels and genetic variation of B-type natriuretic peptide (BNP), has been associated with lower bone mineral density (BMD) values and incidence of osteoporosis in peritoneal dialysis patients, renal transplant recipients, and postmenopausal women. The potential relationship of circulating BNP with osteoporosis in patients with type 2 diabetes mellitus (T2DM), however, has not yet been studied.

Methods: Circulating BNP levels were measured in 314 patients with T2DM, and participants were divided into normal BMD group (n = 73), osteopenia group (n = 120), and osteoporosis group (n = 121). Read More

Traditional and non-traditional risk factors for peripheral artery disease development/progression in patients with type 2 diabetes: the Rio de Janeiro type 2 diabetes cohort study.

Cardiovasc Diabetol 2021 02 27;20(1):54. Epub 2021 Feb 27.

Department of Internal Medicine, University Hospital Clementino Fraga Filho, School of Medicine, Universidade Federal do Rio de Janeiro, Rua Croton, 72, Jacarepagua, Rio de Janeiro, RJ, CEP: 22750-240, Brazil.

Department of Orthopedics & Traumatology, University of Health Sciences, Derince Training & Research Hospital, Kocaeli, Turkey.

Meralgia paresthetica (MP) is a painful mononeuropathy that causes paresthesia, tingling, stinging or a burning sensation in the thigh's anterolateral part due to the entrapment of the lateral femoral cutaneous nerve under the inguinal ligament. The treatment options for MP include conservative or interventional management and must follow an algorithm. The objective is to eliminate the underlying cause if known. Read More

Post-Surgical Inflammatory Neuropathy: An Underappreciated but Critical and Treatable Cause of Postoperative Neuropathy.

Cureus 2020 Dec 5;12(12):e11927. Epub 2020 Dec 5.

Anesthesiology and Perioperative Medicine, University of Alabama at Birmingham, Birmingham, USA.

The diagnosis and management of postoperative nerve injury can be a challenging and frustrating proposition for the patient, surgeon, and anesthesia provider. Unfortunately, in many cases, the true etiology is never elucidated and the injury is ascribed to positioning or a nerve block with "expectant management" being the order of the day, which can result in persistent disability for the patient. However, there is a rare subset of disorders affecting the nervous system that can masquerade as a peripheral nerve injury that warrants further investigation of risk factors and co-morbidities when other common causes of nerve injury are ruled out.

Novel Reconstruction of Complex Central Venous Occlusion Using Supraclavicular Stent Graft in Hemodialysis Patients.

Ann Vasc Surg 2021 May 26;73:185-196. Epub 2020 Dec 26.

DFW Vascular Group, Dallas, TX; Surgery, Methodist Dallas Medical Center, Dallas, TX; TCU School of Medicine, Ft. Worth, TX. Electronic address:

Background: Subclavian vein and brachiocephalic vein occlusions are challenging problems in dialysis patients with ipsilateral upper extremity (UE) vascular access or in need of one. HeRO grafts (Hemodialysis Reliable Outflow, Merit Medical Systems, Inc, South Jordan, UT) have been used to manage such occlusions but patients with chronic hypotension treated with HeRO graft may have threatened patency. We describe an alternative technique using a supraclavicular stent graft to reconstruct the venous outflow, evaluate outcomes of this procedure, and discuss its role in complex hemodialysis patients.

Automated Gait Analysis to Assess Functional Recovery in Rodents with Peripheral Nerve or Spinal Cord Contusion Injury.

J Vis Exp 2020 10 6(164). Epub 2020 Oct 6.

Ludwig Boltzmann Institute for Experimental and Clinical Traumatology; Austrian Cluster for Tissue Regeneration;

Peripheral and central nerve injuries are mostly studied in rodents, especially rats, given the fact that these animal models are both cost-effective and a lot of comparative data has been published in the literature. This includes a multitude of assessment methods to study functional recovery following nerve injury and repair. Besides evaluation of nerve regeneration by means of histology, electrophysiology, and other in vivo and in vitro assessment techniques, functional recovery is the most important criterion to determine the degree of neural regeneration.
