Beliefs and Barriers to COVID-19 Vaccine Acceptance in Three Countries with Different Human Development Index (HDI) Scores: A Comparative Study.

Background: As vaccination is a cornerstone strategy to prevent the spread of COVID-19, this study assessed and compared beliefs about and barriers to COVID-19 vaccination among the population of three countries with different Human Development Index (HDI) scores: Saudi Arabia (very high), India (medium), and Sudan (low).

Methods: A web-based, self-administered structured questionnaire was employed to collect data from the three countries. The questionnaire contained three sections that measured sociodemographic characteristics, participants' beliefs about and attitudes toward COVID-19 vaccines, barriers to receiving COVID-19 vaccines, and scenarios in which there is a possibility to take a COVID-19 vaccine.

Combined Blood Indexes of Systemic Inflammation as a Mirror to Admission to Intensive Care Unit in COVID-19 Patients: A Multicentric Study.

Background: The Coronavirus 2019 is a pandemic that has spread worldwide, threatening human health. The main cause of death in patients with COVID-19 is a systemic pro-inflammatory mechanism that quickly progresses to acute respiratory distress syndrome. Hematological ratios as affordable indicators of inflammatory response were studied in COVID-19 patients.

Can Hematological Ratios Predict Outcome of COVID-19 Patients? A Multicentric Study.

Introduction: Coronaviruses belong to a large family that leads to respiratory infection of various severity. Hematological ratios are indicators of inflammatory response widely used in viral pneumonia with affordability in developing countries.

Purpose: Study the role of the neutrophil lymphocyte ratio (NLR), derived NLR ratio (d-NLR), platelet lymphocyte ratio (PLR), and lymphocyte monocyte ratio (LMR) in predicting the outcome of COVID-19 Egyptian patients.
