Immunogenicity and Safety According to Immunosuppressive Drugs and Different COVID-19 Vaccine Platforms in Immune-Mediated Disease: Data from SAFER Cohort.
Vaccines (Basel)
December 2024
Background/objectives: The effectiveness of COVID-19 vaccine in patients with immune-mediated inflammatory diseases (IMID) depends on the underlying disease, immunosuppression degree and the vaccine regimens. We evaluate the safety and immunogenicity of different COVID-19 vaccine schedules.
Methods: The SAFER study: "Safety and effectiveness of the COVID-19 Vaccine in Rheumatic Disease", is a Brazilian multicentric prospective observational phase IV study in the real-life.
The growing consumer interest in functional foods and healthy eating can unfortunately lead to the spread of misinformation and the belief in food-related myths. This study analyzed Brazilian consumers' perceptions and beliefs about facts and myths regarding functional foods, focusing on attitudes, reference groups, and sociocultural factors affecting their perception. A theoretical model was developed, incorporating constructs such as attitudes (reward, trust, necessity, safety), beliefs, and reference groups.

- Researchers focused on detecting mercury (Hg) in water using a nanocomposite of carbon dots and LAPONITE as an optical sensor due to Hg's environmental and health risks.
- The study used Stern-Volmer analysis at three temperatures to examine the sensor's performance, finding that it selectively detects Hg compared to other metals, with an effective range of 1-40 μM.
- It revealed that static quenching is the main mechanism for Hg detection, likely due to interactions between the sensor's carboxylate groups and Hg, and some parts of the sensor are not fully accessible to the Hg ions.
Background: Pancreatic ductal adenocarcinoma (PDAC) has a known poor prognosis. For a select group, those with BRCA mutations, frontline platinum-based therapy and poly (ADPribose) polymerase inhibitors are options that can potentially lead to survival benefit.
Patients And Methods: We present 2 cases of patients with BRCAmutated pancreatic cancer with liver metastases that achieved a remarkable long-term complete remission on platinum-based chemotherapy.
Article Synopsis
- The study investigates how environmental and climate factors affect the spread of visceral leishmaniasis (VL) in Brazil's Doce River basin, aiming to enhance future surveillance and control efforts.
- It utilizes ecological niche modeling, analyzing 855 VL cases from 2001-2018 to predict current and future disease distributions based on various climatic and environmental variables.
- Key findings indicate that human activities and climate change could increase VL suitable areas by 7% by 2041 and 12% by 2080, emphasizing the need for improved vector control initiatives in the region.
