Background: The use of biological scaffolds in regenerative endodontics has gained much attention in recent years. The search for a new biomimetic scaffold that contains tissue-specific cell homing factors could lead to more predictable tissue regeneration. The aim of this study was to prepare and characterize decellularized bovine dental pulp-derived extracellular matrix (P-ECM) hydrogels for regenerative endodontic applications.

However, the nature of regenerated tissues following REPs remains unpredictable and uncontrollable. Decellularized extracellular matrix scaffolds have gained recent attention as scaffolds for regenerative endodontics.

- Acquired methemoglobinemia occurs when iron in hemoglobin is oxidized, which can lead to symptoms like anemia, cyanosis, and tissue hypoxia, especially after exposure to certain medications.
- A case study highlights a 60-year-old man with multiple health issues who developed methemoglobinemia after taking prescribed supplements during his COVID-19 treatment, presenting with symptoms like difficulty breathing and a chocolate-brown discoloration in his blood.
- The report discusses why elderly patients with COVID-19 are more at risk for methemoglobinemia, the importance of recognizing its clinical and biochemical signs even without specific testing methods, and explores various laboratory methods for assessing oxygen saturation.
Less than 30% of people in Africa received a dose of the COVID-19 vaccine even 18 months after vaccine development. Here, motivated by the observation that residents of remote, rural areas of Sierra Leone faced severe access difficulties, we conducted an intervention with last-mile delivery of doses and health professionals to the most inaccessible areas, along with community mobilization. A cluster randomized controlled trial in 150 communities showed that this intervention with mobile vaccination teams increased the immunization rate by about 26 percentage points within 48-72 h.

Due to social norms, each person's sanitation investment decisions may depend on the decisions of neighbors. We report on a cluster randomized controlled trial conducted with 19,000 households in rural Bangladesh where we grouped neighboring households and introduced (either financial or social recognition) rewards with a joint liability component for the group, or asked each group member to make a private or public pledge to maintain a hygienic latrine.
