Abstract
Obstructive sleep apnea (OSA) is characterized by recurrent episodes of partial (hypopnea) or complete interruption (apnea) in breathing during sleep due to airway collapse in the oral or pharyngeal region. Prospective studies have established the adverse cardiovascular consequences of OSA, including an increased risk for developing hypertension, coronary artery disease, stroke, and heart failure. However, more studies are needed to better assess the impact of OSA, and possible benefit of treatment with continuous positive airway pressure (CPAP) on cardiovascular mortality. The leading pathophysiological mechanisms involved in the changes triggered by OSA include intermittent hypoxemia and re-oxygenation, arousals and changes in intrathoracic pressure. Hypertension is strongly related with activation of the sympathetic nervous system, stimulation of the renin-angiotensin-aldosterone system and endothelial dysfunction. OSA should be suspected in hypertensive individuals, particularly in patients with resistant hypertension. CPAP treatment reduces blood pressure, and its effects are more pronounced in patients with high baseline blood pressure and elevated treatment compliance. At present, no clear evidence supports CPAP treatment for primary or secondary cardiovascular disease prevention.

"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
