Objective: Prolonged fasting has been reported to have a negative effect on patient outcomes. Although fasting is routinely practiced in the emergency department (ED), there is limited evidence on the current status and appropriateness of fasting in the ED. This study examined the status and appropriateness of fasting in the ED and identified the characteristics of patients who experienced unnecessary fasting. Methods: A retrospective observational study was performed at an urban ED in Seoul, Korea. The fasting status and characteristics of adult patients who visited the ED and were admitted or discharged between April 1 and April 30, 2022, were analyzed. A checklist for discontinuing fasting in the ED was used to screen for unnecessary fasting. Results: Among 2,292 patients who met the study inclusion criteria, all patients were instructed to begin fasting upon ED arrival. Fasting was discontinued by the physician’s order in 300 patients (13.1%). Patients remained fasting for 92.0%±23.2% of their total ED length of stay. Of the 1,577 patients eligible for fasting discontinuation according to the checklist, 249 patients (15.8%) were ordered to discontinue fasting, and 1,328 patients (84.2%) experienced unnecessary fasting. Conclusion ED patients spent significant time fasting during their ED length of stay. A high prevalence of unnecessary fasting was identified in the ED.

BACKGROUND: Enteroviruses are known as major pathogen for aseptic meningitis. Although rapid diagnosis for enteroviruses is very essential to exclude bacterial infections in patients with meningitis, classical diagnostic method based on virus isolation is not practicable for timely treatment of patients due to its laborious and time-consuming procedure. Recently molecular methodologies as alternatives are routinely used for rapid and sensitive diagnosis for enteroviruses infections. METHODS: Reverse transcription (RT)-PCR ELISA kit for targeting 5'non-coding region (NCR) with highly conserved genetic identity among all genotypes of enteroviruses was introduced in this investigation. RT-PCR ELISA was evaluated about sensitivity and specificity through virus isolation using clinical specimens from patients suspected of enteroviral infections and enteroviral isolates comparing with conventional RT-PCR identifying them. RESULTS: The detection limit of the RT-PCR ELISA was up to 10-100 folds higher than virus isolation using cell culture and conventional RT-PCR. On comparison between above two methods, the detection rate of RT-PCR ELISA for clinical specimens from patients with aseptic meningitis was 7% higher than that of conventional RT-PCR targeting 5'NCR (P=0.016). CONCLUSIONS: Our results suggest that RT-PCR ELISA developed in this study could be an alternative diagnostic method for the detection of enteroviral genome with high sensitivity and specificity.

PURPOSE: We identified the causative viruses from patients with aseptic meningitis, acute hemorrhagic conjunctivitis and other enterovirus-related diseases to understand the epidemiological patterns and prevailing strains of enterovirus infections each year. MATERIALS AND METHODS: During 1999-2003, we examined 3,260 specimens from 2,939 patients with aseptic meningitis or other clinical manifestations for the presence of enteroviruses by using both cell culture/ neutralisation test and reverse transcription-polymerse chain reaction-sequencing. To investigate the etiological agents which caused an epidemic of acute haemorrhagic conjunctivitis, conjunctival swab samples from acute haemorrhagic conjunctivitis patients showing cytopathic effects in HEp2 cells were tested by enteroviral specific PCR. RESULTS: We identified 603 isolates of enteroviruses (20.5%) among 2,939 cases and 22 serotypes of human enteroviruses were isolated during this 5 year period. Echovirus 13 and coxsackievirus A24 in 2002 and coxsackievirus A9 in 2003 were the first enterovirus to be indentified in Korea since we began the enterovirus surveillance in 1993. While an epidemic of echovirus 13 infection in Korea began in Gwangju and Jeolla province in 2002 and spread to Seoul, Gyunggi, Busan, Ulsan and other regions, echovirus 6 isolates in 2002 were mainly detected in Busan specimens and some Gwangju samples. From the nucleotide sequencing of enteroviral PCR products of conjunctival swab specimens, we found 85% nucleotide homology to coxsackievirus A24 (D90457). CONCLUSIONS: We isolated 603 enteroviral isolates among 2939 cases during 1999-2003. Echovirus 13 and coxsackievirus A24 were the first enterovirus to be identified in Korea and caused nationwide epidemics in 2002.
