Article Synopsis
  • * Researchers collected samples from individuals with respiratory infections, their asymptomatic roommates, and previously confirmed cases, testing them using RT-PCR and next-generation sequencing (NGS).
  • * Results showed that saliva had a higher positive test rate (62.0%) than NP (44.5%) and SN (37.7%) swabs, indicating that saliva is a sensitive and reliable option for COVID-19 diagnosis.

Background: This study sheds light on the proficiency of military medical officers who had received between 2 and 3 years of post-graduate training, in the handling of the difficult airway in a trauma manikin simulator using direct and video laryngoscopes.

Method: One hundred thirty-three doctors from the Singapore Armed Forces Medical Officer Cadet Course were assessed using high-fidelity simulator models with standardised difficult airways (simulator with tongue-swelling and cervical collar). They used the Macintosh direct laryngoscope (DL), King Vision channelled-blade laryngoscope (KVC), King Vision non-channelled blade laryngoscope (KVNC), and the McGrath (MG) laryngoscope on the same model in a randomised sequence.

Failure to secure the airway is an important cause of morbidity and mortality during resuscitations. We compared the rate of successful intubation of the King Vision™ aBlade™ channeled and non-channeled video laryngoscopes, and McGRATH™ MAC video laryngoscope when used by junior doctors to intubate a simulated difficult airway in an out-of-hospital setting. 105 junior doctors were recruited in a crossover study to perform tracheal intubation with the three video laryngoscopes on a simulated difficult airway using the SimMan® 3G manikin.

Objectives: Neighborhood socioeconomic status (SES) can be associated with depression. We aimed to assess prevalence of depression amongst community-dwelling elderly in a multiethnic, urban, low-SES, Asian neighborhood, comparing against a higher SES neighborhood.

Method: The study population involved all residents aged ≥60 years in two Singaporean housing estates comprising owner-occupied public housing (higher SES) and public rental housing (low SES) in 2012.
