Variations in COVID-19 vaccine hesitancy over time: a serial cross-sectional study in five West African countries.

Objectives: This study aims to identify the factors influencing vaccine hesitancy, willingness and its variation over time in order to inform more responsive strategies for increasing vaccination uptake. The specific objectives are: (1) to describe and compare levels of COVID-19 vaccine hesitancy among the general population in rural and urban settings in West Africa over time and (2) to identify factors associated with COVID-19 vaccination willingness and hesitancy among the general population across five West African countries over time.

Design: Following a baseline survey (Wave I), three serial cross-sectional surveys (Waves II-IV) were implemented.

Potential Impact of Physical Activity on Measures of Well-Being and Quality of Life in People with Rare Diseases: A Nationwide Cross-Sectional Study in Italy.

Background: Rare diseases constitute a heterogeneous group of approximately 7000-8000 conditions, distinguished by their low prevalence. Collectively, they present a significant global health challenge, affecting millions of people worldwide. It is estimated that rare diseases affect approximately 10% of the global population, which places a significant burden on individuals, families, and society.

Aesthetic Asian double eyelid surgery: Exploring a novel indication for microsurgery.

Asian double eyelid blepharoplasty and medial canthoplasty aim to enhance eye appearance in individuals of Asian descent. Traditional methods have limitations and may cause complications. This study introduces a microsurgical approach, offering improved precision and reduced scarring, applied to 37 patients over six years.

Decellularized Extracellular Matrix for Modeling Cardiac Extracellular Microenvironment.

The extracellular matrix (ECM) forms most of the tissue microenvironment and is in a constant and dynamic equilibrium with cells. The decellularization process employs physical or chemical methods, or a combination of them, to remove the cellular components of tissues and organs while preserving the architecture and composition of the ECM. Depending on the methodology used, the decellularized ECM (dECM) is then suitable for research or clinical applications.

Production of Cardiac Extracellular Matrix from Adult Human Fibroblasts for Culture Dish Coating.

The myocardium is composed of cardiomyocytes and an even greater number of fibroblasts, the latter being responsible for extracellular matrix production. From the early stages of heart development throughout the lifetime, in both normal and pathological conditions, the composition of the extracellular matrix changes and influences myocardium structure and function. The purpose of the method described here is to obtain the substrate for the culture of cardiac cells in vitro (termed cardiac ECM), mimicking the myocardial extracellular matrix in vivo.
