Randomized Controlled Trial Multicenter Study Comparative Study
Pallidal versus subthalamic deep-brain stimulation for Parkinson's disease.
Deep-brain stimulation is the surgical procedure of choice for patients with advanced Parkinson's disease. The globus pallidus interna and the subthalamic nucleus are accepted targets for this procedure. We compared 24-month outcomes for patients who had undergone bilateral stimulation of the globus pallidus interna (pallidal stimulation) or subthalamic nucleus (subthalamic stimulation). ⋯ Patients with Parkinson's disease had similar improvement in motor function after either pallidal or subthalamic stimulation. Nonmotor factors may reasonably be included in the selection of surgical target for deep-brain stimulation. (ClinicalTrials.gov numbers, NCT00056563 and NCT01076452.)

Randomized Controlled Trial Multicenter Study Comparative Study
Longer therapy, iatrogenic amenorrhea, and survival in early breast cancer.
Chemotherapy regimens that combine anthracyclines and taxanes result in improved disease-free and overall survival among women with operable lymph-node-positive breast cancer. The effectiveness of concurrent versus sequential regimens is not known. ⋯ Sequential ACT improved disease-free survival as compared with doxorubicin-docetaxel or concurrent ACT, and it improved overall survival as compared with doxorubicin-docetaxel. Amenorrhea was associated with improved survival regardless of the treatment and estrogen-receptor status. (ClinicalTrials.gov number, NCT00003782.)

The interleukin-2-mediated immune response is critical for host defense against infectious pathogens. Cytokine-inducible SRC homology 2 (SH2) domain protein (CISH), a suppressor of cytokine signaling, controls interleukin-2 signaling. ⋯ Variants of CISH are associated with susceptibility to diseases caused by diverse infectious pathogens, suggesting that negative regulators of cytokine signaling have a role in immunity against various infectious diseases. The overall risk of one of these infectious diseases was increased by at least 18% among persons carrying the variant CISH alleles.
