Role of Immune Checkpoint Inhibitors in Small Cell Lung Cancer.

Background: Small cell lung cancer (SCLC) accounts for approximately 13% of all lung cancer diagnoses each year. SCLC is characterized by a rapid doubling time, early metastatic spread, and an unfavorable prognosis overall.

New and Emerging Antibiotics for Complicated Intra-Abdominal Infections.

The purpose of this review is to evaluate the efficacy and safety of ceftazidime/avibactam and ceftolozane/tazobactam in patients with complicated intra-abdominal infections (cIAI), and review eravacycline and other agents in the pipeline for management of cIAI. The increasing incidence of multidrug resistant strains of bacteria has led to the need for additional antibiotics with activity against these organisms. There are 2 newly approved antibiotics, ceftazidime/avibactam and ceftolazane/tazobactam for treatment of cIAI.

Single-agent, broad-spectrum fluoroquinolones for the outpatient treatment of low-risk febrile neutropenia.

Objective: To evaluate the use of oral, single-agent, broad-spectrum fluoroquinolones in the treatment of low-risk febrile neutropenia (FN).

Data Sources: MEDLINE via Ovid (1948 to May, week 3, 2011) and EMBASE (1980 to 2011, week 21) were searched using the terms febrile neutropenia, fluoroquinolone, quinolone derivative, levofloxacin, moxifloxacin, and neoplasm. References of selected articles, review articles, and treatment guidelines were reviewed.
