Abstract
With the current high rates of associated morbidity and mortality, proper management of critical illness is vital in the treatment of severely ill patients. Disruptions of key body systems stemming from these illnesses may be attributed to their severity and limited treatment options. Disruption in circadian rhythms caused by critical illnesses may lead to a decreased patient prognosis, as the biological clocks stemming from circadian rhythms play several key roles in regulating our internal pathways. This review will highlight how the occurrence of hyperoxic injury during the progression of critical illness may severely damage circadian rhymicity, and lead to an increased risk of infection, development of disease, severity of symptoms, morbidity and mortality, and dysregulation of multiple body systems. Overall, there is strong evidence suggesting that the disruption of circadian rhythms may be caused by critical illness. Studies performed on several animal models have shown alterations of key genes associated with circadian clock function may heavily contribute to the increased severity of critical illness linked to circadian disruption. This review will aid in further understanding the link between circadian disruption and critical illness.

"Tuberculosis Prevention, Diagnosis and Drug Discovery"
The Nobel Prize-winning discoveries of Mycobacterium tuberculosis and streptomycin have enabled an appropriate diagnosis and an effective treatment of tuberculosis (TB). Since then, many newer diagnosis methods and drugs have been saving millions of lives. Despite advances in the past, TB is still a leading cause of infectious disease mortality ...read more
Blood-based biomarkers in large-scale screening for neurodegenerative diseases
Disease biomarkers are necessary tools that can be employ in several clinical context of use (COU), ranging from the (early) diagnosis, prognosis, prediction, to monitor of disease state and/or drug efficacy. Regarding neurodegenerative diseases, in particular Alzheimer’s disease (AD), a battery of well-validated biomarkers are available, such as cerebrospinal fluid ...read more
