Background And Purpose: Occurrence of stroke has been reported among patients with COVID-19. The present study compares clinical features and outcomes of stroke patients with and without COVID-19.
Methods: The COVID-19 Stroke Study Group (CSSG) is a multicentric study in 18 sites across India to observe and compare the clinical characteristics of patients with stroke admitted during the current pandemic period and a similar epoch in 2019. The present study reports patients of stroke with and without COVID-19 (CoVS and non-CoVS, respectively) seen between February 2020 and July 2020. Demographic, clinical, treatment, and outcome details of patients were collected.
Results: The mean age and gender were comparable between the two groups. CoVS patients had higher stroke severity and extent of cerebral involvement on imaging. In-hospital complications and death were higher among CoVS patients (53.06% vs. 17.51%; < 0.001) and (42.31% vs. 7.6%; < 0.001), respectively. At 3 months, higher mortality was observed among CoVS patients (67.65% vs. 13.43%; < 0.001) and good outcome (modified Rankin score [mRS]: 0-2) was seen more often in non-CoVS patients (68.86% vs. 33.33%; < 0.001). The presence of COVID-19 and baseline stroke severity were independent predictors of mortality.
Conclusions: CoVS is associated with higher severity, poor outcome, and increased mortality. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and baseline stroke severity are independent predictors of mortality.

The first generation of Spike-based COVID-19 vaccines has reduced the risk of hospitalization, serious illness, and death caused by SARS-CoV-2 infections. However, waning immunity induced by these vaccines has failed to prevent immune escape, resulting in the emergence of multiple variants of concern (VOCs) and the prolongation of the COVID-19 pandemic. We hypothesize that a next-generation Coronavirus (CoV) vaccine incorporating highly conserved SARS-CoV-2 T cell antigens would confer potent, broad, and long-lasting cross-protective immunity against multiple VOCs.

Background: SARS-CoVs increase susceptibility to bacterial co-infections, with Pseudomonas aeruginosa frequently detected in COVID-19 patients. Factors such as drug resistance, mobile genetic elements, and biofilm formation further complicate these infections. This study compared these characteristics in P.

Purpose: To evaluate the repeatability of OCT angiography (OCTA) vessel density measurements using fractal analysis in the macula and optic nerve head (ONH) regions.
Design: A prospective longitudinal observational cohort study.
Participants: One hundred sixteen eyes from 71 primary open-angle glaucoma patients with valid macula OCTA scans and 91 eyes from 59 primary open-angle glaucoma patients with valid ONH OCTA scans, with 53 patients contributing scans for both regions.

Background: Radiation-induced long-term toxicities, such as vaginal stenosis, severely impact the quality of life for patients undergoing pelvic radiotherapy (RT) for gynecologic (GYN) malignancies. However, current methods for assessing these toxicities rely on subjective physical examinations and patient-reported symptoms, leading to inconsistencies in grading and suboptimal management.
Purpose: This pilot study investigates the potential of ultrasound-based radiomics, specifically gray level co-occurrence matrix (GLCM) texture metrics, as objective and quantitative biomarkers for evaluating long-term radiation-induced vaginal toxicity.

In cardiac MRI, the field of view (FOV) is adapted to the individual patient's size, influencing spatial resolution and myocardial radiomics. This study aimed to investigate the effects of parametric feature maps on radiomics derived from cine images acquired with different FOV sizes on individuals without myocardial pathologies. In the clinical setting, cardiac MRI scans from clinical care were screened retrospectively for patients without pathological findings, neither in the MRI nor the medical history or follow-up, resulting in 61 included patients.
