Prognostic Role of CSF β-amyloid 1-42/1-40 Ratio in Patients Affected by Amyotrophic Lateral Sclerosis.

Brain Sci 2021 Feb 27;11(3). Epub 2021 Feb 27.

Unit of Neurology, Department of Biomedicine, Neurosciences and Advanced Diagnostics, University of Palermo, 90129, Palermo, Italy.

The involvement of β-amyloid (Aβ) in the pathogenesis of amyotrophic lateral sclerosis (ALS) has been widely discussed and its role in the disease is still a matter of debate. Aβ accumulates in the cortex and the anterior horn neurons of ALS patients and seems to affect their survival. To clarify the role of cerebrospinal fluid (CSF) Aβ 1-42 and Aβ 42/40 ratios as a potential prognostic biomarker for ALS, we performed a retrospective observational study on a cohort of ALS patients who underwent a lumbar puncture at the time of the diagnosis.

Paravertebral anaesthesia with or without sedation versus general anaesthesia for women undergoing breast cancer surgery.

Cochrane Database Syst Rev 2021 Feb 25;2:CD012968. Epub 2021 Feb 25.

Department of Biostatistics, All India Institute of Medical Sciences, New Delhi, India.

Background: Breast cancer is one of the most common cancers among women. Surgical removal of the cancer is the mainstay of treatment; however, tumour handling during surgery can cause microscopic dissemination of tumour cells and disease recurrence. The body's hormonal response to surgery (stress response) and general anaesthesia may suppress immunity, promoting tumour dissemination. Read More

J Neurointerv Surg 2021 Feb 8. Epub 2021 Feb 8.

Cooper Neurological Institute, Cooper University Health Care, Camden, New Jersey, USA

Background: Unprecedented workflow shifts during the coronavirus disease 2019 (COVID-19) pandemic have contributed to delays in acute care delivery, but whether it adversely affected endovascular thrombectomy metrics in acute large vessel occlusion (LVO) is unknown.

Decompressive Hemicraniectomy Associated With Ultrasound-Guided Minimally Invasive Puncture and Drainage Has Better Feasibility Than the Traditional Hematoma Evacuation for Deteriorating Spontaneous Intracranial Hemorrhage in the Basal Ganglia Region: A Retrospective Observational Cohort Study.

Front Neurol 2020 12;11:561781. Epub 2021 Jan 12.

Department of Neurosurgery, The Second Affiliated Hospital of Chongqing Medical University, Chongqing, China.

Spontaneous intracerebral hemorrhage (ICH) is a devastating disease with higher mortality and disability rates; however, ideal surgical management is still to be determined for critical ICH. The purpose of this study was to prove the feasibility and unique clinical value of a novel combination, decompressive hemicraniectomy associated with ultrasound-guided minimally invasive puncture and drainage (DH + MIPD), for deteriorating ICH in the basal ganglia region. According to the enrollment criteria, 168 ICH patients were analyzed retrospectively, of which 86 patients received DH + MIPD and 82 patients received DH associated with traditional hematoma evacuation as the control group.

Clinical Value of 3D-Printed Navigation Technology Combined with Neuroendoscopy for Intracerebral Hemorrhage.

Transl Stroke Res 2021 Jan 25. Epub 2021 Jan 25.

Department of Neurosurgery, Dalang Hospital, Dongguan, Guangdong, China.

Intracerebral hemorrhage (ICH) is the most common form of hemorrhagic stroke with high morbidity and mortality. Rapid and massive bleeding may compress the brain tissue, causing space-occupying and pathological effects, such as reduced local cerebral blood flow, acidosis, and inflammatory and immune responses. Although the development of minimally invasive technique provides a new option for the treatment of ICH, their application is limited due to the difficulty in achieving accurate puncture localization under the guidance of the marks on CT.

KIF5A and the contribution of susceptibility genotypes as a predictive biomarker for multiple sclerosis.

J Neurol 2021 Jan 23. Epub 2021 Jan 23.

MS and Stem Cell Group, Institute of Clinical Neurosciences, Bristol Medical School: Translational Health Sciences, University of Bristol, Clinical Neurosciences Office, 1st Floor, Learning and Research Building, Southmead Hospital, Bristol, BS10 5NB, UK.

There is increasing interest in the development of multiple sclerosis (MS) biomarkers that reflect central nervous system tissue injury to determine prognosis. We aimed to assess the prognostic value of kinesin superfamily motor protein KIF5A in MS by measuring levels of KIF5A in cerebrospinal fluid (CSF) combined with analysis of single nucleotide polymorphisms (SNPs; rs12368653 and rs703842) located within a MS susceptibility gene locus at chromosome 12q13-14 region. Enzyme-linked immunosorbent assay was used to measure KIF5A in CSF obtained from two independent biobanks comprising non-inflammatory neurological disease controls (NINDC), clinically isolated syndrome (CIS) and MS cases.

Unilateral percutaneous vertebroplasty for osteoporotic lumbar compression fractures: a comparative study between transverse process root-pedicle approach and conventional transpedicular approach.

J Orthop Surg Res 2021 Jan 21;16(1):73. Epub 2021 Jan 21.

Department of Spine Surgery, The First Affiliated Hospital of Sun Yat-sen University, No. 58, Zhongshan 2nd Road, Yuexiu District, Guangzhou, 510080, Guangdong, China.

Purpose: Percutaneous vertebroplasty (PVP) is a routine operation for the treatment of osteoporotic lumbar compression fractures (OLCFs). As is well known, unilateral puncture is a common method. However, with the conventional transpedicular approach (CTPA), the cement may be asymmetrically dispersed, so some surgeons use the transverse process root-pedicle approach (TPRPA). Read More
