Article Abstract
Background: Current treatments for several corneal lesions show limited efficacy. Here we report the clinical evaluation of the efficacy of a novel eye drop preparation produced in a public cord blood (CB) bank.
Materials And Methods: In a multicentre, retrospective, consecutive case study we evaluated 33 patients (46 eyes) unresponsive to conventional treatments who required urgent intervention. The patients were given allogeneic eye drops obtained from cord blood platelet lysate (CBED) to treat severe ocular surface lesions under a compassionate use protocol. The CBED were prepared from CB units donated for haematopoietic stem cell transplantation that did not contain the minimum stem cell dose required for this use. Patients were grouped by acute conditions (neurotrophic ulcers: group I; other corneal ulcers: group II; corneal burns: group III), and chronic conditions (ocular graft-versus-host disease: group IV; severe dry eye syndrome: group V). The patients received one or two drops of the product to the affected eye four to six times per day for 19 days. A further 19-day cycle of treatment could be repeated according to the initial clinical response.
Results: Patients received a median of 19 CBED vials (interquartile range 19-57, range 19-442) to complete the therapy. Group I-II-III patients showed full and partial ulcer recovery in 25 (78%) and six (19%) eyes respectively. One eye (3%) did not respond to treatment. For groups IV-V improvement was reported for 12 (85%) eyes and lesions worsened on treatment in both eyes (15%) of one patient. No severe adverse events were directly attributed to CBED.
Discussion: Promptly available CBED resulted in a well-tolerated allogeneic treatment that showed evidence of efficacy in this cohort of patients. These positive results support further studies on CBED from platelet lysate as a novel product of CB banks. A prospective clinical trial in neurotrophic keratitis (NCT03084861) is ongoing to confirm these preliminary data.

Trident Sign: The Key Magnetic Resonance Imaging Finding Distinguishing Spinal Cord Sarcoidosis From Multiple Sclerosis and Seropositive Neuromyelitis Optica Spectrum Disorder.

Spinal cord sarcoidosis, an uncommon manifestation of neurosarcoidosis, presents diagnostic and therapeutic challenges because the condition is rare and has diverse clinical manifestations that can mimic other conditions such as multiple sclerosis and neuromyelitis optica spectrum disorder. A middle-aged African American female with a history of idiopathic intracranial hypertension and hydrocephalus with ventriculoperitoneal shunt presented with progressive, predominantly left-sided gait instability, weakness, and paresthesia. Cerebrospinal fluid showed lymphocytosis, red blood cells, elevated oligoclonal bands, and elevated kappa free light chains, concerning for multiple sclerosis.

Department of Radiology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong, China.
Objective: Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) is a novel steroid sensitive autoimmune disease, without a diagnostic consensus. The purpose of this study was to improve early GFAP-A diagnosis by increasing awareness of key clinical characteristics and imaging manifestations.
Methods: Medical records of 13 patients with anti-GFAP antibodies in serum or cerebrospinal fluid (CSF) were reviewed for cross-sectional and longitudinal analysis of clinical and magnetic resonance imaging (MRI) findings.

Objective: To compare the mineral levels in umbilical vein and artery serum and to analyze the relationship between newborn birth weight and the mineral levels in umbilical vein and artery serum by measuring the mineral levels in umbilical vein and artery serum.
Methods: A cross-sectional study was conducted to recruit 101 pairs of maternal and newborn who were hospitalized in Danyang People's Hospital, Jiangsu Province from June to September 2021 as the participants. After delivery, umbilical vein and artery blood were collected, and the levels of manganese(Mn), iron(Fe), cobalt(Co), copper(Cu), zinc(Zn), selenium(Se), magnesium(Mg) and calcium(Ca) in umbilical vein and artery serum were detected by inductively coupled plasma mass spectrum(ICP-MS).
COVID-19 Serostatus Does Not Affect the Intrauterine Transfer of Micronutrients and Fatty Acids or Maternal-fetal Lymphocyte Cell Composition: An Observational Study.

Department of Obstetrics and Gynecology, Area Hospital, Nampally, Hyderabad, Telangana, India.
Objective: Studies on the effects of coronavirus disease 2019 (COVID-19) on pregnant mothers and their newborns, specifically in relation to their micronutrient status, fatty acids (FAs), and inflammatory status are sparse. We hypothesized that COVID-19 infection would adversely affect the transfer of nutrients, and FAs from mothers to their fetuses via the umbilical cord and maternal-fetal distribution of inflammatory cells. This study aimed to determine the effect of COVID-19 on micronutrients, inflammatory markers, and FAs profiles in pregnant mothers and their newborns' cord blood.

Background: The purpose of this study was to report on 2-year results of vertebral body tethering (VBT), performed under a Food and Drug Administration protocol, to obtain insight into outcomes and complications.
Methods: Forty prospectively enrolled patients with adolescent idiopathic scoliosis (AIS) who had a Sanders score of ≤4 or a Risser score of ≤2 underwent VBT for curves between 40° and 70°. Surgical, radiographic, and patient-reported outcomes were reviewed at a minimum 2-year follow-up.
