Infections caused by resistant gram-negative bacteria are becoming increasingly prevalent and now constitute a serious threat to public health worldwide because they are difficult to treat and are associated with high morbidity and mortality rates. In the United States, there has been a steady increase since 2000 in rates of extended-spectrum β-lactamase-producing Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae, and multidrug-resistant strains of Pseudomonas aeruginosa and Acinetobacter baumannii, particularly among hospitalized patients with intraabdominal infections, urinary tract infections, ventilator-associated pneumonia, and bacteremia. Colonization with resistant gram-negative bacteria is common among residents in long-term care facilities (particularly those residents with an indwelling device), and these facilities are considered important originating sources of such strains for hospitals. ⋯ Although only a few agents are available with activity against resistant gram-negative organisms, two recently released β-lactam/β-lactamase inhibitor combinations - ceftolozane/tazobactam and ceftazidime/avibactam - have promising activity against these organisms. In this article, we review the epidemiology, risk factors, and antibiotic resistance mechanisms of gram-negative organisms. In addition, an overview of treatment options for patients with these infections is provided.

To determine whether acetaminophen or an acetaminophen-codeine combination is associated with an increased risk of acute cerebrovascular and cardiovascular events (ACCEs) in patients with osteoarthritis. ⋯ Our findings indicate that no association can be made between the use of acetaminophen and/or an acetaminophen-codeine combination and the occurrence of ACCEs. This information contributes to support clinicians in the choice of acetaminophen therapy for osteoarthritis-related pain, especially in those patients presenting with cerebrovascular and cardiovascular morbidities or related risk factors.

Severe cardiac effects, including cardiac arrest, are a rare complication of high-dose propafenone intake. Among patients who experience cardiac arrest, the survival rate is low. This report presents the case of a young female patient who developed cardiac arrest linked to propafenone intake. ⋯ However, after the administration of intravenous lipid emulsion (ILE), vital signs and cardiac functions resolved and the patient survived. This case is the second to describe the successful use of ILE for propafenone intoxication. However, as all of the findings of this patient were clearly linked to propafenone, we believe the benefits of ILE were more clearly defined in this case than in the other.

There has been a 10-year hiatus in the approval of a new pharmacotherapy for patients with chronic heart failure with a reduced ejection fraction (HFrEF). Combining an angiotensin receptor blocker, valsartan, with sacubitril, an inhibitor of neprilysin, results in increasing levels of natriuretic peptides that counterbalance high circulating levels of neurohormones in HFrEF. This has resulted in the development of a new agent, LCZ696. A comprehensive overview of LCZ696, its pharmacology, its role in the pathophysiology of HFrEF, completed and future clinical trial information, specific critical issues, and the place of LCZ696 in HFrEF therapy are presented.

Project Re-Engineered Discharge is a discharge nurse education (DNE) and pharmacist follow-up telephone intervention protocol that was shown to decrease rehospitalization significantly. The specific value of the pharmacist intervention was not originally evaluated. The objective of this study was to determine the impact of a pharmacist telephone intervention during the transition of care process on the rate of unplanned hospitalization within 30 days of patient discharge. ⋯ Patients unable to be contacted by a pharmacist after hospital discharge were more likely to be readmitted or visit the emergency department in the 30 days following discharge. A pharmacist telephone intervention as part of a comprehensive discharge protocol can have a positive impact on patients during the transition of care process by reducing incidence of unplanned hospital utilization.
