Vasopressors and Inotropes in Sepsis.

Vasopressor and inotropes are beneficial in shock states. Norepinephrine is considered the first-line vasopressor for patients with sepsis-associated hypotension. Dobutamine is considered the first-line inotrope in sepsis, and should be considered for patients with evidence of myocardial dysfunction or ongoing signs of hypoperfusion.

The persistent problem of malaria: addressing the fundamental causes of a global killer.

Despite decades of global eradication and control efforts and explosive global economic development, malaria is the most important vector-borne disease of our day, killing more people today than 40 years ago and affecting millions worldwide, particularly poor residents of tropical regions. Global eradication efforts from the 1950s through the 1980s largely failed, leaving vector and parasite resistance in their wake. The persistence of malaria and the magnitude of its effects call for an action paradigm that links the traditional proximal arenas of intervention with malaria's fundamental causes by addressing the environmental, economic, and political dimensions of risk.
