Neuro-Ophthalmic Complications of COVID-19 Infection and Vaccination.

The COVID-19 pandemic has led to the identification of new disease phenotypes associated with infection by the SARS-CoV-2 virus. This includes multiple neuro-ophthalmological sequelae, which have been associated with COVID-19 infection and administration of COVID-19 vaccines. Some of these associations have a plausible pathophysiological link to the infection or vaccination but true causation has yet to be established.

Therapeutic effect of combination vitamin D3 and siponimod on remyelination and modulate microglia activation in cuprizone mouse model of multiple sclerosis.

Stimulation of remyelination is critical for the treatment of multiple sclerosis (MS) to alleviate symptoms and protect the myelin sheath from further damage. The current study aimed to investigate the possible therapeutic effects of combining vitamin D3 (Vit D3) and siponimod (Sipo) on enhancing remyelination and modulating microglia phenotypes in the cuprizone (CPZ) demyelination mouse model. The study was divided into two stages; demyelination (first 5 weeks) and remyelination (last 4 weeks).

Pregnant and Breastfeeding Women's Attitudes and Fears Regarding COVID-19 Vaccination: A Nationwide Cross-Sectional Study in Saudi Arabia.

Introduction: Contracting coronavirus disease (COVID-19) during pregnancy has been linked to an increased risk of severe maternal and fetal complications. Mass vaccination is considered a promising solution to successfully combat the COVID-19 pandemic. It includes vaccinating of pregnant and breastfeeding women.

Chronic Distal Biceps Tendon Rupture With Allograft Reconstruction.

Rupture of the distal biceps tendon typically occurs after an eccentric extension load is applied to the elbow. Chronic distal biceps ruptures are uncommon and are complicated by tendon, muscle retraction, and tissue atrophy. Here, we present the case of a 26-year-old male soldier.

Exploring the Impact of the COVID-19 Quarantine on the Severity of Headache, Migraine, and Stress in Saudi Arabia.

Purpose: This cross-sectional study aimed to investigate the impact of COVID-19 quarantine on the severity of migraine symptoms and stress among adults in Saudi Arabia.

Patients And Methods: Between December 2020 and February 2021, 1212 participants aged 18-65 years completed an online self-administered questionnaire that covered sociodemographic data, self-administered questions, the ID migraine screener, numeric pain rating scale, and the perceived stress scale. Statistical analyses were performed using SPSS.

Spirometric values and chest pain intensity three days post-operative coronary artery bypass graft surgery.

Aim: Coronary artery bypass graft surgery (CABG) is proved to have ventilatory complications and reduction in spirometric values. This study aimed to examine the hypothesis that reduction of post-operative chest pain intensity would be associated with improvement in the spirometric values for patient underwent CABG.

Materials And Method: 26 cardiac patients recruited for this study.
