Risk factors and incidence of long-COVID syndrome in hospitalized patients: does remdesivir have a protective effect?

BACKGROUND: The definition of 'long-COVID syndrome' (LCS) is still debated and describes the persistence of symptoms after viral clearance in hospitalized or non-hospitalized patients affected by coronavirus disease 2019 (COVID-19). AIM: In this study, we examined the prevalence and the risk factors of LCS in a cohort of patients with previous COVID-19 and followed for at least 6 months of follow-up. DESIGN: We conducted a prospective study including all hospitalized patients affected by COVID-19 at our center of Infectious Diseases (Vercelli, Italy) admitted between 10 March 2020 and 15 January 2021 for at least 6 months after discharge. Two follow-up visits were performed: after 1 and 6 months after hospital discharge. Clinical, laboratory and radiological data were recorded at each visit. RESULTS: A total of 449 patients were included in the analysis. The LCS was diagnosed in 322 subjects at Visit 1 (71.7%) and in 206 at Visit 2 (45.9); according to the post-COVID-19 functional status scale we observed 147 patients with values 2-3 and 175 with values >3 at Visit 1; at Visit 2, 133 subjects had the score between 2-3 and 73 > 3. In multivariate analysis, intensive care unit (ICU) admission (OR = 2.551; 95% CI = 1.998-6.819; P = 0.019), time of hospitalization (OR = 2.255; 95% CI = 1.018-6.992; P = 0.016) and treatment with remdesivir (OR = 0.641; 95% CI = 0.413-0.782; P < 0.001) were independent predictors of LCS. CONCLUSIONS: Treatment with remdesivir leads to a 35.9% reduction in LCS rate in follow-up. Severity of illness, need of ICU admission and length of hospital stay were factor associated with the persistence of PCS at 6 months of follow-up

Determination of the Ileal Digestibility of Proteins and Amino Acids from Biscuit Bran and Wheat Gluten in Swine

To determine the apparent (AIDCP) and standardized (SIDCP) ileal digestibility coefficients of the protein and the apparent (AIDAA) and standardized (SIDAA) ileal digestibility coefficients of amino acids from biscuit bran and wheat gluten were used six castrated males swine in growth, on average weight from 22 to 60kg, with a T cannula on the terminal ileum, distributed in a randomized block design with three treatments, two periods and two repetitions per period. Each animal was considered a repeat. Treatments consisted of a protein free diet (PFD) for determination of the endogenous loss, PFD + biscuit bran (BB) and PFD + wheat gluten (WG). Each period lasted for six days, five days of adaptation of animals to the diet and 24 hours of collection of ileal digestion. The AIDCP of BB and WG were 82.33 and 90.07%, respectively and the SIDCP of BB and WG were 89.17% and 95.60%, respectively. The SIDAA were on average 80.84% (lysine), 83.94% (threonine), 90.57% (methionine + cystine) and 87.15% (valine) to BB. The SIDAA for the WG were on average 91.01% (lysine), 90.97% (threonine), 95.82% (methionine + cystine) and 90.04% (valine). The SID of protein and essential amino acids and non-essential elements identified in this study were on average, respectively, 89.17%, 88.54% and 89.20% of biscuit branand 95.60%, 93.71% and 89.20% of wheat gluten
