Background: OME is an accumulation of serous or mucoid fluid in the middle ear cavity with an intact tympanic membrane and without any sign of acute infection.

Aims: This study aimed to determine the prevalence of otitis media with effusion among preschool and school-age children aged 1-10 years in private and public schools in Calabar municipality and the correlations between otoscopic findings and Jerger's diagnostic criteria among study participants.

Methods: This school-based descriptive cross-sectional study used a multistage sampling technique to recruit participants.

Background: Predisposing factors for otitis media with effusion are multifactorial, ranging from genetic and anatomical abnormalities to environmental factors and inflammation of the nose and adjacent structures.

Aim: The study determined the risk factors for otitis media with effusion (OME) among children in Calabar Municipality.

Methods: This was a descriptive, cross-sectional, community-based study including children aged 1-10 years randomly selected from government and privately owned daycares, nurseries (preschool), and primary schools.

Article Synopsis
  • The study focused on the impact of COVID-19 in Honduras, examining the clinical characteristics and outcomes of hospitalized patients during a significant outbreak from October 2020 to March 2021.
  • A total of 929 cases were analyzed, revealing a high case fatality rate of 50.1%, with patients suffering from comorbidities facing increased mortality risks.
  • Limited ICU capacity meant that only a fraction of patients requiring critical care were admitted, and those who did not receive appropriate care had a much lower chance of survival compared to those who did.

Objectives: Many bacterial species naturally take up DNA from their surroundings and recombine it into their chromosome through homologous gene transfer (HGT) to aid in survival and gain advantageous functions. Herein we present the first characterization of Type IV pili facilitated natural competence in Fusobacterium nucleatum, which is a Gram-negative, anaerobic bacterium that participates in a range of infections and diseases including periodontitis, preterm birth, and cancer.

Methods: Here we used bioinformatics on multiple Fusobacterium species, as well as molecular genetics to characterize natural competence in strain F.

Article Synopsis
  • SARS-CoV-2 can cause mild respiratory illness, but severe cases often involve a harmful immune response that affects coagulation, especially in resource-limited Latin American countries.
  • This study analyzed 210 Honduran COVID-19 patients to identify clinical features and biomarkers that predict poor outcomes, finding higher death rates among males, older individuals, and those with prolonged symptoms or elevated D-dimer levels.
  • The findings highlight the importance of using clinical and laboratory assessments to better predict prognosis and manage COVID-19 patients in low-middle income settings.
