Objectives: To identify differences in the mean vitamin D concentrations in samples obtained from a private laboratory in Quito and to explore their relationship with the pre-pandemic and pandemic periods spanning from 2018 to 2022.

Design: A combination of an interrupted time series design and a retrospective cross-sectional approach.

Setting And Participants: The study involved 9285 participants who had their 25-hydroxyvitamin D (25(OH)D) levels tested at a well-known private laboratory in Quito, Ecuador, from 2018 to 2022.

Article Synopsis
  • * The study analyzed 40 unique isolates from clinical samples between 2018 and 2019, identifying bacteria using the API 20A system and measuring antibiotic effectiveness with Sensititre anaerobe MIC plates.
  • * Findings revealed 11 isolates resistant to metronidazole, with only 2 carrying the significant resistance gene, and 5 imipenem-resistant isolates, suggesting a need for ongoing monitoring and understanding of resistance mechanisms to improve treatment options.

Aims: We described the presence of Helicobacter pylori (HP) and estimated the prevalence of primary and secondary resistance using molecular detection in gastric biopsies of Ecuadorian patients.

Methods And Results: 66.7% (238/357) of the patients demonstrated the presence of HP using CerTest qPCR.

Objectives: To date, reported SARS-CoV-2 reinfection cases are mainly from strains belonging to different clades. As the pandemic advances, a few lineages have become dominant in certain areas leading to reinfections by similar strains. Here, we report a reinfection case within the same clade of the initial infection in a symptomatic 28-year-old-male in Quito-Ecuador.
