ReviewEpidemiology and prevention of carbapenem-resistant Enterobacteriaceae in the United States.
Carbapenem-resistant Enterobacteriaceae (CRE) are multidrug-resistant organisms with few treatment options that cause infections associated with substantial morbidity and mortality. CRE outbreaks have been increasingly reported worldwide and are mainly due to the emergence and spread of strains that produce carbapenemases. ⋯ In addition to efforts in individual facilities, effective CRE control requires coordination across all healthcare facilities in a region. This review describes the current epidemiology and surveillance of CRE in the United States and the recommended approach to prevention.

EditorialPolymyxins for the treatment of extensively-drug-resistant Gram-negative bacteria: from pharmacokinetics to bedside.
The initial use of polymyxins, polymyxin B and colistin (administered as a pro-drug colistin methanesulfonate sodium [CMS]), mostly relied on old pharmacokinetic (PK) studies that lacked appropriate methodology. In recent years, many PK studies in both animals and humans have provided more consistent evidence supporting better use of these invaluable antibiotics. ⋯ Although many questions are still unresolved, there are consistent data able to improve clinical practice when prescribing initial and maintenance doses of both polymyxin B and CMS. Considering the importance of optimal use of polymyxins, this editorial discusses recent PK findings and how to take advantage of them at the bedside to improve the treatment of patient with extensively-drug-resistant Gram-negative bacterial infections.

ReviewDolutegravir for the treatment of adult patients with HIV-1 infection.
Dolutegravir, is a second generation integrase inhibitor that had recently received United States Food and Drug Administration and European Commission approval for the treatment of adult patients with HIV-1 infection. Dolutegravir provides distinct advantages compared with first generation integrase inhibitors. Unlike raltegravir, dolutegravir can be given once daily for patients who are antiretroviral treatment naïve. ⋯ In Phase III clinical trials, dolutegravir-containing regimens have demonstrated either non-inferiority or superiority to current first line agents such as raltegravir, darunavir/ritonavir, and efavirenz containing regimens. Moreover, dolutegravir may be effective for patients with a history of raltegravir and/or elvitegravir resistance. Dolutegravir will likely play a major role in the management of patients with HIV-1 infection, and will be aided when coformulation with abacavir/lamivudine as a single pill, once-daily regimen is available.
