New variants of the virus responsible for the coronavirus disease 2019 (COVID-19) pandemic continue to emerge. However, little is known about the effect of these variants on clinical outcomes. This study evaluated the risk factors for poor pulmonary lung function test (PFT). Methods: The study retrospectively analyzed 87 patients in a single hospital and followed up by performing PFTs at an outpatient clinic from January 2020 to December 2021. COVID-19 variants were categorized as either a non-delta variant (November 13, 2020–July 6, 2021) or the delta variant (July 7, 2021–January 29, 2022). Results: The median age of the patients was 62 years, and 56 patients (64.4%) were male. Mechanical ventilation (MV) was provided for 52 patients, and 36 (41.4%) had restrictive lung defects. Forced vital capacity (FVC) and diffusion capacity of the lung for carbon monoxide (DLCO ) were lower in patients on MV. Male sex (odds ratio [OR], 0.228) and MV (OR, 4.663) were significant factors for decreased DLCO . The duration of MV was associated with decreased FVC and DLCO . However, the type of variant did not affect the decrease in FVC (P=0.750) and DLCO (P=0.639). Conclusions: Among critically ill COVID-19 patients, 40% had restrictive patterns with decreased DLCO . The reduction of PFT was associated with MV, type of variants.

Enteral nutrition (EN) supply within 48 hours after intensive care unit (ICU) admission improves clinical outcomes. The “new ICU evaluation & development of nutritional support protocol (NICE-NST)” was introduced in an ICU of tertiary academic hospital. This study showed that early EN through protocolized nutritional support would supply more nutrition to improve clinical outcomes.
This study screened 170 patients and 62 patients were finally enrolled; patients who were supplied nutrition without the protocol were classified as the control group (n=40), while those who were supplied according to the protocol were classified as the test group (n=22).
In the test group, EN started significantly earlier (3.7±0.4 days vs. 2.4±0.5 days, P=0.010). EN calorie (4.0±1.0 kcal/kg vs. 6.7±0.9 kcal/kg, P=0.006) and protein (0.17±0.04 g/kg vs. 0.32±0.04 g/kg, P=0.002) supplied were significantly higher in the test group. Although EN was supplied through continuous feeding in the test group, there was no difference in complications such as feeding hold due to excessive gastric residual volume or vomit, and hyper- or hypo-glycemia between the two groups. Hospital mortality was significantly lower in the group that started EN within 1.5 days (42.9% vs. 11.8%, P=0.018). The proportion of patients who started EN within 1.5 days was higher in the test group (40.9% vs. 17.5%, P=0.044).
The NICE-NST may improve EN supply and mortality of critically ill patients without increasing complications.
