Patterns of Progression of Nonproliferative Diabetic Retinopathy Using Non-Invasive Imaging.

Purpose: To identify progression of nonproliferative diabetic retinopathy (NPDR) in patients with type 2 diabetes by combining optical coherence tomography angiography (OCTA) metrics and color fundus photography (CFP) images.

Methods: This study was a post hoc analysis of a prospective longitudinal cohort study (CORDIS, NCT03696810) with 2-year duration. This study enrolled 122 eyes.

Mannose-coupled AAV2: A second-generation AAV vector for increased retinal gene therapy efficiency.

Inherited retinal diseases are a leading and untreatable cause of blindness and are therefore candidate diseases for gene therapy. Recombinant vectors derived from adeno-associated virus (rAAV) are currently the most promising vehicles for therapeutic gene delivery to the retina. However, there is a need for novel AAV-based vectors with greater efficacy for ophthalmic applications, as underscored by recent reports of dose-related inflammatory responses in clinical trials of rAAV-based ocular gene therapies.

Clinical Features of COVID-19 on Patients With Neuromyelitis Optica Spectrum Disorders.

Background And Objectives: To describe the clinical features and disease outcomes of coronavirus disease 2019 (COVID-19) in patients with neuromyelitis optica spectrum disorder (NMOSD).

Methods: The Neuroimmunology Brazilian Study Group has set up the report of severe acute respiratory syndrome (SARS-CoV2) cases in patients with NMOSD (pwNMOSD) using a designed web-based case report form. All neuroimmunology outpatient centers and individual neurologists were invited to register their patients across the country.

Association of peripheral blood pressure with gray matter volume in 19- to 40-year-old adults.

Objective: To test whether elevated blood pressure (BP) relates to gray matter (GM) volume (GMV) changes in young adults who had not previously been diagnosed with hypertension (systolic BP [SBP]/diastolic BP [DBP] ≥140/90 mm Hg).

Methods: We associated BP with GMV from structural 3T T1-weighted MRI of 423 healthy adults between 19 and 40 years of age (mean age 27.7 ± 5.

[Hemorrheologic changes in the hypertensive elderly patient].

The aim of this work is to make a review of the papers about hemorheology and hypertension on the aged. The paucity of the works did not allow any conclusions. However, some of the drugs frequently used have tight links with hemorheology, which must be in our minds when dealing with old people.
