ABSTRACT
@#We have previously isolated a novel avian Orthobunyavirus, Kedah Fatal Kidney Syndrome (KFKS) virus from a broiler farm in Kedah, Malaysia in 2020 with a severe kidney lesion in chickens. The virus was designated as KFKS2_CS virus. Sequence analysis of partial nucleocapsid (N) and nonstructural (NSs) sequence of this virus showed the highest sequence identity with previous KFKS1 from Malaysia (100%) and 97% with a zoonotic Umbre (UMB) virus, which was reported to cause encephalitis in immunocompromised humans in India. Phylogenetic analysis revealed that this virus was clustered together with previous KFKS1 virus from Malaysia, UMB and Cristoli viruses. This study aimed to assess the zoonotic potential of this KFKS2_CS virus in vitro by determining its ability to inhibit the production of interferon (IFN) in human glioblastoma multiforme (GBM) brain cells using reverse-transcriptase polymerase reaction (RT-PCR). This virus blocked the production of interferon-a in this human brain cells. In conclusion, this KFKS2_CS virus may have a zoonotic potential and become a public health concern in the future.
ABSTRACT
Corticosteroids used for chronic obstructive pulmonary disease [COPD] exacerbations can cause hyperglycemia in hospitalized patients, and hyperglycemia may be associated with increased mortality, length of stay [LOS], and re-admissions in these patients. We did three retrospective studies using charts from July 2008 through June 2009, January 2006 through December 2010, and October 2010 through March 2011. We collected demographic and clinical information, laboratory results, radiographic results, and information on LOS, mortality, and re-admission. Glucose levels did not predict outcomes in any of the studied cohorts, after adjustment for covariates in multivariable analysis. The first database included 30 patients admitted to non-intensive care unit [ICU] hospital beds. Six of 20 non-diabetic patients had peak glucoses above 200 mg/dl. Nine of the ten diabetic patients had peak glucoses above 200 mg/dl. The maximum daily corticosteroid dose had no apparent effect on the glucose levels. The second database included 217 patients admitted to ICUs. The initial blood glucose was higher in patients who died than those who survived using bivariate analysis [P= 0.015; odds ratio, OR, 1.01] but not in multivariable analysis. Multivariable logistic regression analysis also demonstrated that glucose levels did not affect LOS. The third database analyzing COPD re-admission rates included 81 patients; the peak glucose levels were not associated with re-admission. Our data demonstrate that COPD patients treated with corticosteroids developed significant hyperglycemia, but the increase in blood glucose levels did not correlate with the maximum dose of corticosteroids. Blood glucose levels were not associated with mortality, LOS, or re-admission rates
