ReviewHospital-based strategies to reduce antibiotic resistance: are they valid in the community setting?
Antimicrobial resistance is an increasing problem worldwide in both the hospital and community settings. Various approaches have been proposed and tested mainly in the hospital environment to reduce this problem; however, few of these have been examined from the perspective of applicability to reversing community-based resistance. ⋯ This inexorable increase is occurring in the face of a dearth of new antibiotics for community use and even fewer for treating resistant nosocomial gram-negative species. The possible strategies and consequences are discussed.

ReviewPrevention of catheter-related bloodstream infections in the neonatal intensive care setting.
Nosocomial infection causes substantial morbidity and mortality among neonates treated in the neonatal intensive care setting. Colonization and subsequent infection of central venous catheters leading to catheter-related bloodstream infection is among the most common causes of nosocomial sepsis in this patient population. Prevention of catheter-related bloodstream infection is a major challenge and numerous strategies have been attempted in this context with varying success. Given the dynamic epidemiology of nosocomial infection among neonates and the emergence of antimicrobial resistance, novel prevention strategies are urgently required.

ReviewCandida infections in the intensive care unit: epidemiology, risk factors and therapeutic strategies.
This article reviews the epidemiology, predisposing risk factors and outcome of systemic Candida spp. infections in the intensive care unit setting. Incidence of systemic Candida infections in patients requiring intensive care has increased substantially in recent years; while diagnosis of serious Candida infection may be difficult, the clinical conditions which predispose patients to these infections are now better understood and effective antifungal therapies are becoming increasingly available. ⋯ Patients at highest risk for Candida infection may be potential candidates for early, presumptive therapy. In this article we review antifungal treatment, including the use of polyenes, azoles and echinocandines, and the role of prophylaxis.

Treatment and prevention of malaria in pregnancy: opportunities and challenges.
Control of malaria in pregnancy through prevention or treatment may save lives of mothers and babies. Selection of drugs for treatment of infected pregnant women, or for prevention in exposed populations is problematic owing to resistance to established drugs and lack of pregnancy-specific safety and pharmacological data for new drugs. ⋯ Our principal challenges are to decide which drugs to develop for use in malaria treatment and prevention in pregnancy and to develop mechanisms to rapidly and comprehensively evaluate their safety. Prevention of pregnancy malaria by vaccination may also become possible, but targets must be closely defined, and strategies developed to test candidates against meaningful end points.

ReviewDrotrecogin alfa (activated) in the treatment of severe sepsis.
Severe sepsis is a common and frequently fatal condition. Evidence showing a link between the coagulation system and the inflammatory response to sepsis led to the development of drotrecogin alfa (activated) as an agent in the treatment of severe sepsis. ⋯ This recombinant form of the natural anticoagulant, activated protein C, has been demonstrated to reduce mortality in a large randomized controlled, Phase III study involving 1690 patients, even though the results of this and subsequent studies and the licensing of drotrecogin alfa (activated) have generated considerable debate. Administration of drotrecogin alfa (activated) is associated with an increased risk of bleeding and its use is contraindicated in patients with a high risk of bleeding or recent hemorrhagic events.
